- Masseter and temporalis muscle electromyography findings after lower third molar extraction(2018) Buesa Bárez, José María; Martín Ares, María; Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Sanz Alonso, Javier; Cortés-Bretón Brinkman, Jorge; Martínez González, José MaríaBackground: The main clinical application of electromyography is to detect abnormalities in muscle function, to assess muscle activity for purposes of recruitment, and in the biomechanics of movement. Objectives: To analyze electromyography (EMG) findings for masticatory muscles during chewing following surgical extraction of lower third molars, and to determine any correlation between pain, inflammation, trismus, and the EMG data registered. Material and Methods: This prospective study included 31 patients. Surface EMG was used to study masseter and temporalis muscle function before lower third molar extraction and 72 hours and seven days after surgery. Clinical variables, pain, inflammation, and trismus were registered before and after surgery. Results: Studying the area and size of the masticatory muscles, higher values were found for temporalis than masseter muscles, regardless of the surgical side, which points to the greater involvement of the temporalis muscle in mastication. Comparing the side where surgery had been performed with the non-surgical side, a sharp and statistically significant reduction in amplitude and area were noted on the surgical side reflecting major functional affectation. One week after surgery, amplitude and area had almost returned to base-line values, indicating almost complete recovery. While pain decreased progressively after surgery, inflammation peaked at 72 hours, while mouth opening reached a minimum at this time, returning to normality within the week. Conclusions: Surgical extraction of lower third molars produces changes to electromyography activity that are more evident during the first hours after surgery and closely related to the intensity of pain suffered and the patient?s inflammatory responses, although they are not related to mouth opening capacity.
- Evolution of oral neoplasm in an andalusian population (Spain)(2018) Flores Ruiz, Rafael; Castellanos Cosano, Lizett; Serrera Figallo, María Angeles; Gutiérrez Corrales, Aida; Castillo de Oyagüe, Raquel; Gutiérrez Pérez, José Luis; Torres Lagares, DanielHead and neck cancer are one of the most common neoplasm pathologies in humans. The aim of this study was to analyze the type, characteristics, treatment and evolution of oral neoplasm or precancerous lesion in a sample of Andalusian population (Spain) derived from the Oncology Rehabilitation Hospital Unit during a period of 20 years. A retrospective descriptive study was carried out during the years 1991 and 2011 analyzing the type, characteristics, treatment and follow-up of oral neoplasm in the Oral and Maxillofacial Surgery Unit of the Universitary Hospital ?Virgen del Rocío?. The inclusion criteria were patients whose underlying pathology was any type of benign or malignant neoplasm or presence of precancerous lesion that, after treatment, had been referred to the Prosthetic Rehabilitation Unit. Of the initial analyzed sample of 60 patients, only 45 patients met the inclusion criteria. Of the final sample analyzed, 31 subjects were men (68.9%) and 14 women (31.1%) (p = 0.0169). The mean age of the sample was 57 years ± 13.83, been more frequently in older people with more than 50 years (73.3%) (p = 0.0169). The most common type of neoplasm was epidermoid carcinoma (64.4%). The site most frequently found in squamous cell carcinoma was the floor of the mouth (31%). The most frequent treatment modality was surgery with postoperative radiotherapy (42.2%). All patients had a minimum follow-up of 5 years, and a recurrence in this period was identified in 11.1% of the sample. Multivariate logistic regression showed a statistically significant association for the variables age (p = 0.0063) and smoking (p = 0.0434). Epidermoid carcinoma is the most frequent tumor in the oral cavity, where increase age and smoking are confirmed as associated risk factors.
- Prospective study of the 532 nm laser (KTP) versus diode laser 980 nm in the resection of hyperplastic lesions of the oral cavity(2018) Bargiela Pérez, Patricia; González-Merchán, Jorge; Diaz Sanchez, Rosa Maria; Serrera Figallo, María Angeles; Volland, Gerd; Jörgens, Martin; Gutiérrez Pérez, José Luis; Torres Lagares, DanielThe aim of this study is to evaluate the resection of hyperplastic lesions on the buccal mucosa comparing the 532nm laser (KTP), versus diode 980nm laser, considering pain, scarring, inflammation and drug consumption that occurred postoperatively with each lasers. A prospective study of consecutive series of 20 patients in two groups that presents hyperplastic lesions on the buccal mucosa. The choice of the KTP laser or diode 980nm laser for the surgery was made randomly. The power used was 1.5W in both groups in a continuous wave mode with a 320 ?m optical fiber. Parameters of pain, scarring, inflammation and consumption of drugs were recorded by a Numerical Rating Scale and evaluated postoperatively. These recordings were made the day of the surgery, 24 hours after, 14 and 28 days after. Pain and inflammation was light - moderate. The consumption of paracetamol was somewhat higher in the diode 980nm laser versus the KTP laser after 24 hours, although data was not statistically significant; significant differences were found after 28 days in regards to pain (p = 0.023) and inflammation (p = 0.023), but always in the absence parameter so we find no pain in both lasers. Scarring in the two types of laser showed no differences along the visits, with not detected scar retractable. Although there is a slight histological difference regarding the KTP laser in the oral soft tissues for clinical use, both wavelengths are very suitable for excision of oral fibroma.
- Preliminary evaluation of near-infrared vein visualization technology in the screening of palatal blood vessels(2018) Yaprak, Emre; Kayaalti-Yuksek, SibelAvoidance from palatal blood vessel rupture is a major concern during the palatal soft tissue graft surgery. There is no defined chair-side and case-specific palatal blood vessel detection approach to facilitate the harvesting process. The objective of this pilot study is to assess the feasibility of a near-infrared vein visualization system in the screening process of palatal blood vessels. An extraoral vein visualization device (AccuVein AV400) was applied to a total of 304 hemi-maxilla of 152 individuals by two blind examiners. The study groups were classified according to their maximum inter-incisal measurements. The distances between the coronal border of the vessel image and the mid-palatal gingival margins of the adjacent teeth were measured and in each group. The correlations among the measurements were evaluated within groups. The blood vessel to the adjacent teeth measurements exhibited no statistical difference between both examiners in all subjects (p<0.001). Correlations between the examiners gradually increased in all groups as the mouth opening rates of the subjects were increased (p<0.001). In the current state, screening of the palatal blood vessels via near-infrared vein visualization technology seems to be not suitable for every individual due to the restrictive effect of mouth opening. However, the promising results of this preliminary study demonstrated increasing consistency between the measurements of the examiners as the inter-incisal distance increase which emphasized the need an intraoral version of the device. Considering the lack of local decision-making technology for the detection of palatal blood vessels, further studies are required for development and optimization of these systems.
- A clinical diagnosis of oral leukoplakia : a guide for dentists(2018) Carrard, Vinicius C.; Waal, Isaäc Van derIn view of the many white or predominantly white lesions of the oral mucosa it is a challenge for dentists to clinically identify a leukoplakia, being a potentially (pre)malignant lesion. Based on the available literature and experience of the authors the parameters of a clinical diagnosis of oral leukoplakia have been studied. A guide has been presented that should help dentists to establish a clinical diagnosis of leukoplakia as accurate as possible. Probably in most parts of the world dentists will need the help of a specialist for confirmation or exclusion of the clinical diagnosis of oral leukoplakia and for further management of the patient, including patient information.
- Low-level laser therapy and anesthetic infiltration for orofacial pain in patients with fibromyalgia : a randomized clinical trial(2018) de Souza, Rebeca-Cecília-Vieira; Tavares-de-Sousa, Emerson; Scudine, Kelly-Guedes-de Oliveira; Meira, Ussânio-Mororó; Silva, Emanuel Dias de Oliveira; Gomes, Ana Claudia Amorim; Limeira-Junior, Francisco-de AssisTo compare the analgesic effect of anesthetic infiltration of lidocaine 2% and low-level laser therapy (LLLT) by GaAlAs into tender points of patients with orofacial pain and fibromyalgia (FM). A randomized clinical trial was performed with adults (N=66) that were allocated into two groups (1:1): Group A received LLLT irradiation by Diode Laser GaAlAs (780nm) with expositions twice a week during six weeks and Group B was treated with anesthetic infiltration of lidocaine 2% without vasoconstrictor once a week for four weeks. The pain assessment included the Visual Analogic Scale (VAS) and tenderness to palpation. No dropout and adverse effect was observed during the study. The pain decreased significantly in each group after the treatment (p=0.0001, ?=1.0), even though no statistical difference was found between both treatments (p=0.46, ?= 0.82). The presence of tender points decreased after both treatments, with responsively in some types of masticatory muscles (p<0.05) except posterior temporalis muscle. The patients? perception showed that both treatments were effective and a few patients reported that the treatment did not improve welfare. The LLLT by GaAlAs and anesthetic infiltration of lidocaine 2% were equally effective to control orofacial pain in FM individuals.
- Oral appliance therapy in obstructive sleep apnea : long-term adherence and patients? experiences(2018) Saglam-Aydinatay, Banu; Taner, TülinDespite the advances in the treatment of obstructive sleep apnea (OSA) with mandibular advancement appliances (MAA), their effectiveness is dependent on the patients? compliance. Our aims were to evaluate the long-term adherence to MAA therapy and patients? experiences of the treatment in OSA. Sixty-nine patients (52 males, 17 females; Mean age: 54.4±10.8 years) were included in the study. The subjects were mild (56%) and moderate (44%) OSA patients who had been treated using MAA at least 4 years prior to the study. A phone survey was used to determine the demographic characteristics of the patients, as well as to assess self-reported adherence to therapy, subjective long-term effectiveness, and patient experiences with the appliance. Descriptive statistics, Pearson Chi-square test, and independent samples t-test were used for data analysis. Only 22 (32%) patients reported using the appliance regularly. Most of the non-adherent patients had stopped using their appliances in the first year (55%). The mean duration of appliance use was 33.5 months (Median: 12 months). No significant differences in appliance type, OSA severity, educational level, gender, marital status, income status, employment status or place of residence existed between adherent and non-adherent subjects. Adherent subjects were significantly younger than non-adherent subjects (Age: 50.6 ± 11.9 versus 56.1 ± 9.9, p<0.05). The most common reasons reported by patients were inability to adapt to the appliance (62%) and pain in the temporomandibular joint (38%). The most common factors associated with continued usage were effectiveness (100%) and ease of use (64%). The overall long-term nonadherence to MAA therapy in mild-to moderate OSA patients was high suggesting that barriers to MAA therapy adherence should be prevented to increase the efficiency of oral appliance treatment in OSA and achieve better outcomes for this disease.
- Lower lip squamous cell carcinoma in patients with photosensitive disorders : analysis of cases treated at the Brazilian National Cancer Institute (INCA) from 1999 to 2012(2018) Borges, Jorena-Fraga-Pimenta; Lanaro, Nattália-Di; Bernardo, Vagner-Gonçalves; Albano, Rodolpho M.; Dias, Fernando; Faria, Paulo Antonio Silvestre de; Pinto, Luis-Felipe-Ribeiro; Lourenço, Simone de Queiroz ChavesLower lip squamous cell carcinoma (LLSCC) is a common malignancy of the head and neck, being mainly a consequence of a chronic exposure to ultraviolet (UV) light solar radiation. Here, we evaluated the clinicopathological profile of patients with photosensitive disorders (xeroderma pigmentosum, lupus erythematosus and albinism) that developed LLSCC. Data from patients who had a diagnosed LLSCC with a prior xeroderma pigmentosum, lupus erythematosus or albinism diagnosis that were treated at INCA from 1999 to 2012 were collected from patients? medical records (n=16). The control group was composed of 68 patients with LLSCC without a medical history of photosensitivity. The clinicopathological data of this study population were collected and the association between these variables was analyzed by Fisher?s exact test. Survival curves were constructed using the Kaplan?Meier method and compared by log-rank test. All statistical analyses were performed using SPSS statistics package. The mean age of patients in the photosensitive and non-photosensitive groups was 42 years and 67 years, respectively (p<0.0001). A previous history of malignant diseases was more common in the photosensitive group (p=0.001). In both groups, most tumors showed a pathological stage I/II disease. Overall and cancer-specific survival were not statistically different. However, disease-free interval showed a significant difference (p=0.01) between the photosensitive and non-photosensitive patients. Photosensitive patients presented LLSCC at earlier age but it usually was not the primary tumor in these patients. Furthermore, a more aggressive pathological behavior was not seen when compared with tumors from non-photosensitive patients. The disease-free interval was lower in photosensitive patients, as expected.
- Nonsyndromic cleft lip and palate, gastric cancer and tooth agenesis(2018) Cardoso, Eudes-Freire; Martelli, Daniella Reis; Machado, Renato Assis; Della Coletta, Ricardo; de Souza, Júlia-Duarte; Barbosa, Fernanda-Tófani; de Figueiredo, Maria-Fernanda-Leite; Coelho, Luiz-Gonzaga-Vaz; Martelli Júnior, HercílioTo determine the frequency of nonsyndromic cleft lip and/or palate (NSCL/P) in first-degree relatives and to analyze the prevalence of tooth agenesis in patients with gastric cancer. This cross-sectional, observational, case-control study included 798 patients attended at hospital Santa Casa in Montes Claros, Minas Gerais and Alfa Institute of Gastroenterology of the Federal University of the Minas Gerais. Information on basic demographic data and tooth agenesis of both groups and their family history of NSCL/P in first-degree relatives were evaluated. The collected information was stored in a database and analyzed using statistical program SPSS® version 21.0 and the values with p<0.05 were considered statistically significant. Of the 798 patients, 113 (14.16%) consisted of the case group and 685 of the control group (85.84%). Non-Caucasian males were the most affected, although no differences among the groups were detected. Of all participants (n=798), 66 (8.27%) presented tooth agenesis and 25 (3.13%) presented oral cleft in first degree relative. Our results no found increase in the frequency of tooth agenesis in patients with gastric cancer and in the frequency of NSCL/P in the first-degree relatives of patients with gastric cancer.
- Oral cancer : a multicenter study(2018) Dhanuthai, Kittipong; Rojanawatsirivej, Somsri; Thosaporn, Watcharaporn; Kintarak, Sompid; Subarnbhesaj, Ajiravudh; Darling, Mark; Kryshtalskyj, Eugene; Chiang, Chun-Pin; Shin, Hong-In; Choi, So-Young; Lee, Sang-shin; Shakib, Pouyan-AminiTo determine the prevalence and clinicopathologic features of the oral cancer patients. Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as between Asian and non-Asian oral cancer patients.
- Effect of implant placement depth on the peri-implant bone defect configurations in ligature-induced peri-implantitis : an experimental study in dogs(2018) Huang, Baoxin; Zhang, Li; Xu, Li; Zhu, Weidong; Witek, Lukasz; Tovar, Nick; Coelho, Paulo G.; Meng, HuanxinThe subcrestal placement of implant platform has been considered a key factor in the preservation of crestal bone, but the influence of implant placement depth on bone remodeling combined with peri-implantitis is not fully understood. The aim of this study was to assess the effect of the crestal or subcrestal placement of implants on peri-implant bone defects of ligature-induced peri-implantitis in dogs. Eight weeks after tooth extraction in six beagle dogs, two different types of implants (A: OsseoSpeed?, Astra, Mölndal, Sweden; B: Integra-CP?, Bicon, Boston, USA) were placed at either crestal or subcrestal (-1.5 mm) positions on one side of the mandible. Ligature-induced peri-implantitis was initiated four weeks after the installation of the healing abutment connections. After 12 weeks, tissue biopsies were processed for histological analyses. Supra-alveolar bone loss combined with a shallow infrabony defect was observed in crestal level implants while deep and wide infrabony defects were present in subcrestal level groups. Subcrestal groups showed significantly greater ridge loss, depths and widths of infrabony defects when compared to crestal groups (P<0.001). Within the limitations of the animal study, it can be stated that the implants at subcrestal position displayed greater infra-osseous defect than implants at crestal position under an experimental ligature-induced peri-implantitis.
- Panoramic and skull imaging may aid in the identification of multiple myeloma lesions(2018) Morais-Faria, Karina; Brandao, Thais-Bianca; Silva, Wagner-Gomes; Pereira, Juliana; Neves, Frederico-Sampaio; Alves, Marcelo-Corrêa; Shintaku, Werner-Harumiti; Lopes, Márcio Ajudarte; Ribeiro, Ana-Carolina-Prado; Migliorati, Cesar A.; Santos Silva, Alan RogerThe purpose of this study was to investigate the presence of punched-out lesions in craniofacial bones using three different radiographic protocols in a large cohort of patients. One hundred fifty-five MM patients were evaluated using panoramic and skull (frontal and lateral) radiographs, which were performed in all patients at the time of MM diagnosis. The diagnostic potential for detecting punched-out lesions was compared among the radiographic techniques. MM punched-out lesions were identified in 135 (87%) panoramic radiographs, 141 (91%) frontal and 144 (93%) lateral skull radiographs. Punched out-lesions were synchronously present in skull and jawbones in 129 (83.23 %) cases. The lesions were detected exclusively in skull in 18 (11.61%) cases and exclusively in jawbones in 6 (3.87%) cases. Punched out-lesion mainly affected the skull and the jawbones in a synchronous way (p<0.001) rather than separately. All investigated radiographic techniques (panoramic, frontal and lateral skull approaches) demonstrated high detection rates for MM punched-out lesions in craniofacial bones. Panoramic radiography may aid to the radiographic protocols to identify multiple myeloma bone lesions.
- The Epidemiology, treatment, and complication of ameloblastoma in East-Indonesia : 6 years retrospective study(2018) Ruslin, Muhammad; Hendra, Faqi N.; Vojdani, Arian; Hardjosantoso, David; Gazali, Mohammad; Tajrin, Andi; Wolff, Jan; Forouzanfar, TymourAmeloblastoma is a neoplasm classified as a benign epithelial odontogenic tumor of the jaws, grow slowly and are locally invasive. The aim of the present study was to investigate the incidence, treatment, and complication of patients with ameloblastoma in East-Indonesia during six years retrospective study. This retrospective study included 84 patients who were diagnosed with ameloblastoma from 2011 to 2016. There were 56 patients with treatment data available. Data from each patient, including gender, age, histologic type, the size of the tumor, radiologic form, tumor location, type of treatment, and complication were reviewed and analyzed retrospectively. Fourteen patients were diagnosed with unicystic ameloblastoma (25%), thirty two patients with multicystic follicular ameloblastoma (57%) and ten patients with an unspecified multicystic ameloblastoma (18%). A total of about 35 patients were treated conservatively (62.5%) and 21 patients were treated radically (37.5%). Swelling was present as a pre-operative complication in all 56 cases (100%). There were no complaints concerning speech. The majority findings of the histologic type were multicystic ameloblastoma and their location were in the mandible. Most ameloblastoma were treated conservatively and reconstructions were made with only titanium plates and not bone graft.
- Epidemiologic study of odontogenic and non-odontogenic cysts in children and adolescents of a Brazilian population(2018) Silva, Leorik-Pereira da; Gonzaga, Amanda-Katarinny-Goes; Severo, Mara-Luana-Batista; Barros, Caio-César-da Silva; de Medeiros, Ana-Miryam-Costa; Souza, Lélia Batista de; Dantas da Silveira, Ericka JanineThe objective of this study was to describe the frequency of cystic lesions in a Brazilian population of patients histopathologically diagnosed in the first and second decade of life. Retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1980 and 2016. A total of 2.114 biopsy records of pediatric patients were analyzed with oral and maxillofacial lesions. Data such as gender, age, anatomical location, and histopathological diagnosis were collected and categorized. Among all oral and maxillofacial lesions (n=2.114), were diagnosed 294 cases of odontogenic cysts (13.9%) and 16 cases of non-odontogenic cysts (0.8%). The most frequent lesions in each group were, respectively: radicular cyst (n=145) and epidermoid cyst (n=4). These lesions were most common in female (n=158), with a mean age of 14 years. For intraosseous lesions, the mandible (n=148) was the most affected anatomic site; moreover, the floor of the mouth (n=6) was most affected by cysts in soft tissues. Odontogenic cysts were relatively common in population studied, but non-odontogenic cysts were rare in these patients.
- Occupational group, educational level, marital status and deleterious habits among individuals with maxillofacial fractures : retrospective study(2018) Silveira Esses, Diego Felipe; Costa, Fabio Wildson Gurgel; Sá, Carlos-Diego-Lopes; Silva, Paulo-Goberlânio-de Barros; Bezerra, Thâmara-Manoela-Marinho; Carvalho, Francisco-Samuel-Rodrigues; de Medeiros, José-Rômulo; Soares, Eduardo Costa StudartTo investigate the occupational profile, educational level, marital status and deleterious habits to the health of patients with maxillofacial fractures of a population of northeastern Brazil. A retrospective study of patients records admitted to the Division of Oral and Maxillofacial Surgery at the Walter Cantídio University Hospital (Fortaleza, Brazil) who sustained maxillofacial fractures was conducted in the period between 2006 and 2015. A total of 338 patients rendered 355 fractures. Males were the most affected (p<0.001), with prevalence in the third decade of life (p<0.001). There was a predominance of motorcycle accidents (p<0.001), home workers (p<0.001), low educational status (p = 0.032), and no cigarette use (p<0.001) or alcohol (p = 0.023). Fractures of the zygomatic-orbital complex were the most prevalent in the sample (p<0.001). The sociodemographic profile exerted a significant influence on the epidemiological profile of maxillofacial fractures in a Brazilian population during the study period.
- Correlation between the visibility of submandibular fossa and mandibular canal cortication on panoramic radiographs and submandibular fossa depth on CBCT(2018) Bayrak, Seval; Demirturk-Kocasarac, Husniye; Yaprak, Emre; Ustaoglu, Gulbahar; Noujeim, Marcel E.To identify a correlation between the submandibular fossa (SF) visibility and mandibular canal (MC) cortication on panoramic image and the depth of SF measured on CBCT and also correlation between the depth of SF and vertical and horizontal location of MC on CBCT. 500 CBCT scans and panoramic radiographs were evaluated. SF depth types were classified as type I (< 2mm); type II (2-3mm) and type III (> 3mm) on CBCT. Visibility of SF and the cortication of MC on panoramic radiographs were compared with the depth of SF on CBCT. Distances between MC and mandibular inferior, buccal and lingual cortices were measured. No statistically significant correlation was found between radiolucent appearances of SF, cortication of MC, and depth of SF. The deepest part of the fossa was in the second molar area followed by third and first molars. Negative weak correlations were found between B-MC, L-MC distances and depth of SF. Visibility of SF and cortication of MC on panoramic radiographs did not correlate with the depth of SF. A marked radiolucent submandibular fossa on panoramic image does not undoubtedly indicate a deep fossa, which emphasizes the importance of 3-D imaging in implant planning.
- Autogenous teeth used for bone grafting : a systematic review(2018) Gual Vaqués, Patricia; Polis Yanes, Carlos; Estrugo Devesa, ALbert; Ayuso Montero, Raúl; Marí Roig, Antonio; López López, JoséRecently, bone graft materials using permanent teeth have come to light, and clinical and histological outcomes of this material have been confirmed by some studies. The aim of this systematic review was to evaluate the reliability of the autogenous tooth bone graft material applied to alveolar ridge augmentation procedures. A systematic review of literature was conducted analyzing articles published between 2007 and 2017. The following four outcome variables were defined: a) implant stability b) post-operative complication c) evaluation of implant survival and failure rates, and d) histological analysis. A total of 108 articles were identified; 6 were selected for review. Based on the PICO (problem, intervention, comparison, outcome) model, the chief question of this study was: Can patients with alveolar ridge deficiency be successfully treated with the autogenous teeth used as bone graft? The mean primary stability of the placed implants was 67.3 ISQ and the mean secondary stability was 75.5 ISQ. The dehiscence of the wound was the most frequent complication with a rate of 29.1%. Of the 182 analyzed implants, the survival rate was 97.7% and the failure rate was 2.3%. In the histological analysis, most of studies reported bone formation. There is insufficient evidence regarding the effects of autogenous teeth used for bone grafting to support any definitive conclusions, although it has been shown clinically safe and good bone forming capacity, and good results are shown about implant stability.
- Oral findings in Williams-Beuren syndrome(2018) Ferreira, Shirlene-Barbosa-Pimentel; Viana, Melissa-Machado; Maia, Naiara-Gonçalves-Fonseca; Leão, Letícia Lima; Machado, Renato Assis; Della Coletta, Ricardo; Burle Aguiar, Marcos José; Martelli Júnior, HercílioWilliams-Beuren syndrome (WBS; OMIM #194050) is a developmental disorder characterized by congenital heart disease, intellectual disability, dysmorphic facial features and ophthalmologic abnormalities. Oral abnormalities are also described in clinical manifestations of the disease. This paper describes orofacial features in patients with WBS. Seventeen patients with a confirmed molecular diagnosis of WBS were examined for oral abnormalities through clinical oral evaluations and panoramic radiography. Malocclusion, specifically with dental midline deviation, and high-arched palate were the most common findings. The present results contribute to knowledge on the orofacial manifestations of WBS. Since such patients with WBS may develop severe oral abnormalities, early detection and treatment can help improve their quality of life.
