- Prevalence of carotid artery calcifications among 2,500 digital panoramic radiographs of an adult Brazilian population(2018) Santos, Juliana-Mara-Oliveira; Soares, Guilherme-Costa; Negreiros Nunes Alves, Ana Paula; Kurita, Lúcio Mitsuo; Silva, Paulo-Goberlânio-de Barros; Costa, Fabio Wildson GurgelThe aim of the present study was to analyze the epidemiological data of digital panoramic radiographs revealing suggestive images of carotid artery calcifications (CAC) from a Northeast Brazilian population. A cross-sectional retrospective study was conducted with 2,500 digital panoramic radiographs obtained from a single imaging reference center in Northeast Brazil. Images from individuals of both sexes and older than 18 years were included and those that did not cover the region of cervical vertebrae or presented low radiographic quality were excluded. Data were analyzed regarding prevalence, location (bilateral, right or left), sex, and age using the Chi-square test at the significance level of 5%. An amount of 96 (4%) patients presented suggestive images of CAC. The female sex (p=0.003) and individuals aged up to 70 years (p=0.002) were statically significant. 40.4% were found bilaterally, 37.6% on the right side (p<0.001) and 22% on the left side. In conclusion, this study showed a low prevalence of suggestive images of CAC in digital panoramic radiographs from a Northeast Brazilian population. It was observed a higher prevalence of CAC associated with female sex, older patients, and right side location.
- Evaluation of the osteoclastogenic process associated with RANK / RANK-L / OPG in odontogenic myxomas(2018) Gonzalez Galvan, Maria del Carmen; Mosqueda Taylor, Adalberto; Bologna Molina, Ronell; Setién Olarra, Amaia; Marichalar Mendia, Xabier; Aguirre Urízar, José ManuelOdontogenic myxoma (OM) is a benign intraosseous neoplasm that exhibits local aggressiveness and high recurrence rates. Osteoclastogenesis is an important phenomenon in the tumor growth of maxillary neoplasms. RANK (Receptor Activator of Nuclear Factor ?appa B) is the signaling receptor of RANK-L (Receptor activator of nuclear factor kappa-? ligand) that activates the osteoclasts. OPG (osteoprotegerin) is a decoy receptor for RANK-L that inhibits pro-osteoclastogenesis. The RANK / RANKL / OPG system participates in the regulation of osteolytic activity under normal conditions, and its alteration has been associated with greater bone destruction, and also with tumor growth. To analyze the immunohistochemical expression of OPG, RANK and RANK-L proteins in odontogenic myxomas (OMs) and their relationship with the tumor size. Eighteen OMs, 4 small (<3 cm) and 14 large (> 3cm) and 18 dental follicles (DF) that were included as control were studied by means of standard immunohistochemical procedure with RANK, RANKL and OPG antibodies. For the evaluation, 5 fields (40x) of representative areas of OM and DF were selected where the expression of each antibody was determined. Descriptive and comparative statistical analyses were performed with the obtained data. There are significant differences in the expression of RANK in OM samples as compared to DF (p = 0.022) and among the OMSs and OMLs (p = 0.032). Also a strong association is recognized in the expression of RANK-L and OPG in OM samples. Activation of the RANK / RANK-L / OPG triad seems to be involved in the mechanisms of bone balance and destruction, as well as associated with tumor growth in odontogenic myxomas.
- Localized gingival enlargements. A clinicopathological study of 1187 cases(2018) Tamiolakis, Paris; Chatzopoulou, Eirini; Frakouli, Fiorina; Tosios, Konstantinos I.; Sklavounou-Andrikopoulou, AlexandraTo describe the incidence, demographic and clinical features of 1187 localized gingival enlargements. 1187 cases of localized gingival enlargements diagnosed during a 20-year period were retrospectively collected. The patients? gender and age, as well as the main clinical features of the tumors were retrieved from the biopsy report forms. The 1187 localized gingival enlargements represented 6.23% of 19.044 biopsies performed during the study period. 756 females and 427 males were affected with a mean age of 41.92±19.68 years. The lesions appeared as smooth (52.4%), granular (17.9%) or rough (13.16%) tumors, elastic (50.73%) or soft (29.56%) in consistency and red (60.8%), normal (28.58%) or white (8.17%) in color. The majority of the lesions (85.17%) were reactive in origin with pyogenic granuloma being the most common. In 1.1% of the cases a diagnosis of malignant lesion was rendered. All localized gingival enlargements should be submitted for microscopic examination because in approximately 1% of cases they are malignant.
- Possible association between obesity and periodontitis in patients with Down syndrome(2018) Culebras Atienza, Elena; Silvestre Donat, Francisco Javier; Silvestre Rangil, JavierThe present study was carried out to evaluate the possible association between obesity and periodontitis in patients with DS, and to explore which measure of obesity is most closely correlated to periodontitis. A prospective observational study was made to determine whether obesity is related to periodontal disease in patients with DS. The anthropometric variables were body height and weight, which were used to calculate BMI and stratify the patients into three categories: < 25(normal weight), 25-29.9 (overweight) and ? 30.0 kg/m2 (obese). Waist circumference and hip circumference in turn was recorded as the greatest circumference at the level of the buttocks, while the waist/hip ratio (WHR) was calculated. Periodontal evaluation was made of all teeth recording the plaque index (PI), pocket depth (PD), clinical attachment level (CAL) and the gingival index. We generated a multivariate linear regression model to examine the relationship between PD and the frequency of tooth brushing, gender, BMI, WHI, WHR, age and PI. Significant positive correlations were observed among the anthropometric parameters BMI, WHR, WHI and among the periodontal parameters PI, PD, CAL and GI. The only positive correlation between the anthropometric and periodontal parameters corresponded to WHR. Upon closer examination, the distribution of WHR was seen to differ according to gender. Among the women, the correlation between WHR and the periodontal variables decreased to nonsignificant levels. In contrast, among the males the correlation remained significant and even increased. In a multivariate linear regression model, the coefficients relating PD to PI, WHR and age were positive and significant in all cases. Our results suggest that there may indeed be an association between obesity and periodontitis in male patients with DS. Also, we found a clear correlation with WHR, which was considered to be the ideal adiposity indicator in this context.
- Differential metallothionein expression in oral lichen planus and amalgam-associated oral lichenoid lesions(2018) Mendes, Gabriela-Geraldo; Servato, João-Paulo-Silva; Borges, Fabiana-Custódio; Rosa, Roberta-Rezende; Siqueira, Carla-Silva; Faria, Paulo Rogério de; Loyola, Adriano-Mota; Vitorino Cardoso, SérgioOral lichen planus (OLP) is a chronic inflammatory disease mediated by T cells, which manifests as reticular (white) or erosive (red) lesions, that are eventually painful. Oral lichenoid lesion (OLL) are distinguished from OLP by the presence of precipitating factors. The aim of this study was to evaluate whether the presence of metallothionein, which is involved in anti-apoptotic pathways and the anti-oxidative response, could serve as a differential diagnostic for OLP and OLL. We evaluated the expression of metallothionein in 40 cases of OLP and 20 cases of OLL using immunohistochemistry. White OLP has higher concentrations of metallothionein than red OLP in basal and parabasal layers. Moreover, metallothionein was more frequently observed in the cytoplasm and nuclei of basal cells in OLP patients compared to the same regions of OLL cases. Metallothionein levels are related to OLP severity and may contribute to a differential diagnosis between OLP and OLL.
- Changes in dimension of neurovascular canals in the mandible and maxilla : a radiographic finding in patients diagnosed with MRONJ(2018) Goller Bulut, Duygu; Özcan, Gözde; Avci, FatmaThe aim of this retrospective study was to compare the morphological features of neurovascular canals and foramina of patients with medication-related osteonecrosis of the jaws (MRONJ) and healthy individuals by using cone beam computed tomography (CBCT). The CBCT images of 58 patients under bisphosphonate therapy diagnosed with MRONJ and age gender- matched controls were retrospectively evaluated. The diameter of mandibular and nasopalatine canal and mandibular, mental and lingual foramina were measured on several sections of CBCT. The value of mental index (MI) and panoramic mandibular index (PMI) were also assessed. The mean value of diametric measurements for all neurovascular canals and foramina in MRONJ patients were narrower than controls. Left mandibular foramen was the most affected area (p<0.001). There were significantly difference in all measurements of mental foramen, lingual foramen and mandibular incisive canal between two groups (p<0.05). PMI of MRONJ subjects were also significantly differences in both sides (p<0.05). In MRONJ patient, neurovascular canals and foramina are affected due to the alterations in bone remodeling. Therefore, the diametric measurement of neurovascular canals and assessment of MI and PMI on CBCT, is a potentially useful method for detection of early changes associated with bisphosphonate therapy and for predict areas where new necrosis may occur.
- miR-1226 detection in GCF as potential biomarker of chronic periodontitis: a pilot study(2018) Micó Martínez, Pablo; García Giménez, José Luis; Seco Cervera, Marta; López Roldán, Andrés; Almiñana Pastor, Pedro J.; Alpiste Illueca, Francisco M.; Pallardó, Federico V.The study and identification of new biomarkers for periodontal disease, such as microRNAs (miRNAs), may give us more information about the location and severity of the disease and will serve as a basis for treatment planning and disease-monitoring. miRNAs are a group of small RNAs which are involved in gene regulation by binding to their messenger RNA target (mRNA). In this pilot study, the procedure for purifying miRNAs from gingival crevicular fluid (GCF) was, for the first time, described. In addition, the concentration of miRNAs in GCF was analyzed and compared between patients with moderate or severe chronic periodontitis (CP) and healthy controls. GCF samples were collected from single-rooted teeth of patients with moderate or severe CP (n=9) and of healthy individuals (n=9). miRNAs were isolated from GCF using miRNeasy Serum/Plasma kit (Qiagen, CA. USA). Reverse transcription polymerase chain reaction (qRT-PCR) was used to determine the expression of a series of miRNAs candidates that are related to bone metabolism. The significance of differences in miRNA levels between both groups was determined using Mann-Whitney U test. The results from this pilot study indicate that miRNAs can be isolated from GCF. Six different miRNAs were analyzed (miR-671, miR-122, miR-1306, miR-27a, miR-223, miR-1226), but only miR-1226 showed statically significant differences between the CP group and healthy controls (p<0.05). This miRNA was downregulated in patients with CP. Within the limitations of the present study, it may be concluded that miR-1226 can be a promising biomarker for periodontal disease, adding relevant information to common clinical parameters used for diagnosis and prognosis of periodontitis.
- Temporal headache and jaw claudication may be the key for the diagnosis of giant cell arteritis(2018) Peral Cagigal, B.; Pérez Villar, Álvaro; Redondo González, Luis Miguel; García-Sierra, Claudia; Morante Silva, Marina; Madrigal Rubiales, Beatriz; Verrier Hernández, AlbertoTemporal artery biopsy (TAB) is a surgical procedure with a low positive yield. The purpose of this study is to determine which variables are the most important in the giant cell arteritis (GCA) diagnosis. The objective of this evaluation is to improve the percentage of positive temporal artery biopsy and if possible, avoid the biopsy in some cases. A retrospective clinical study consisted of 90 patients who had undergone TAB at the Río Hortega Hospital (Spain) from January 2009 to December 2016. Clinical findings, erythrocyte sedimentation rates (ESR) and other laboratory parameters, American College of Rheumatology (ACR) criteria for GCA score and biopsy results were recorded. Nineteen (21.1%) biopsies were positive for GCA. The mean age in positive TAB was 78.6 years old (SD 7.93), and 73.7% were female. Presence of temporal headache (p = 0.003), jaw claudication (p = 0.001), abnormal artery exploration (p = 0.023), elevated erythrocyte sedimentation rate (p = 0.035), CRP (p = 0.018) and platelets (p = 0.042), were significantly associated with GCA. Multivariate logistic regression revealed that the best predictors for the diagnosis of GCA are headache and jaw claudication, adjusted by sex, age, and temporal exploration. TAB has benefit only for patients who score a 2 or 3 on the ACR criteria for GCA without biopsy. These findings highlight the need for a better diagnostic strategy for patients with suspected temporal arteritis.
- Association of time under immunosuppression and different immunosuppressive medication on periodontal parameters and selected bacteria of patients after solid organ transplantation(2018) Schmalz, Gerhard; Berisha, Lisa; Wendorff, Horst; Widmer, Florian; Marcinkowski, Anna; Teschler, Helmut; Sommerwerck, Urte; Haak, Rainer; Kollmar, Otto; Ziebold, DirkAim of this study was to investigate the association of the time under immunosuppression and different immunosuppressive medication on periodontal parameters and selected periodontal pathogenic bacteria of immunosuppressed patients after solid organ transplantation (SOT). 169 Patients after SOT (lung, liver or kidney) were included and divided into subgroups according their time under (0-1, 1-3, 3-6, 6-10 and >10 years) and form of immunosuppression (Tacrolimus, Cyclosporine, Mycophenolate, Glucocorticoids, Sirolimus and monotherapy vs. combination). Periodontal probing depth (PPD) and clinical attachment loss (CAL) were assessed. Periodontal disease severity was classified as healthy/mild, moderate or severe periodontitis. Subgingival biofilm samples were investigated for eleven selected potentially periodontal pathogenic bacteria using polymerasechainreaction. The mean PPD and CAL as well as prevalence of Treponema denticola and Capnocytophaga species was shown to be different but heterogeneous depending on time under immunosuppression (p<0.05). Furthermore, only the medication with Cyclosporine was found to show worse periodontal condition compared to patients without Cyclosporine (p<0.05). Prevalence of Porphyromonas gingivalis, Tannerella forsythia and Fusobacterium nucleatum was reduced and prevalence of Parvimonas micra and Capnocytophaga species was increased in patients under immunosuppression with Glucocorticoids, Mycophenolate as well as combination therapy. Time under and form of immunosuppression might have an impact on the clinical periodontal and microbiological parameters of patients after SOT. Patients under Cyclosporine medication should receive increased attention. Differences in subgingival biofilm, but not in clinical parameters were found for Glucocorticoids, Mycophenolate and combination therapy, making the clinical relevance of this finding unclear.
- One or two ligatures inducing periodontitis are sufficient to cause fatty liver(2018) Pessoa, Larissa-dos Santos; da Silva, Felipe Rodolfo Pereira; Alves, Even-Herlany-Pereira; de Carvalho França, Luiz Felipe; di Lenardo, David; Carvalho, Joaquina-dos Santos; Martins, Victor-Brito-Dantas; Sousa, Francisca-Beatriz-de Melo; Drumond, Karina-Oliveira; Medeiros, Jand-Venes-Rolim; de Oliveira, Jefferson-Soares; Vasconcelos, Daniel Fernando PereiraPeriodontitis is a chronic disease that due to an intense inflammatory response triggers systemic changes such as hepatic alterations. This study aimed to compare hepatic damage in rats that received experimental periodontitis at one or two periodontal sites with ligatures. Eighteen rats were separated into three groups: control, without ligature; periodontitis 1, with one ligature; and periodontitis 2, with two ligatures. The following parameters were assessed: gingival bleeding index, probing pocket depth, tooth mobility, alveolar bone loss, malondialdehyde (MDA) and myeloperoxidase (MPO) activity in periodontal tissue; histopathological evaluation of hepatic tissue (steatosis score); glutathione levels (GSH), MDA, MPO, cholesterol and triglycerides in the liver; and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Periodontal evaluation data showed that the periodontitis model worked well. The groups with periodontitis did not differ significantly in relation to MPO activity and MDA levels in the gingival samples, but they were significantly different when compared with the control group. Steatosis was observed in the histological analysis of the groups with periodontitis, but between the periodontitis groups, two ligatures did not cause increase in steatosis score. The levels of GSH, MDA, total cholesterol and triglycerides in the hepatic tissue were not altered between groups with periodontitis, but they showed significant differences in comparison with the control group. The activity of MPO in hepatic tissue and serum levels of AST and ALT did not present significant difference among the three groups. In conclusion, our results demonstrated that one or two ligatures inducing periodontitis were both sufficient to cause fatty liver. Steatosis caused by two ligatures did not present larger extension and severity than steatosis caused by one ligature.
- Virtual Planning and 3D printing modeling for mandibular reconstruction with fibula free flap(2018) Rena, Wenhao; Gaoa, Ling; Li, Shaoming; Chen, Cheng; Li, Fan; Wang, Qibo; Zhi, Yuan; Song, Jianzhong; Dou, Zhichao; Xue, Lingfa; Zhia, KeqianThis study was to evaluate the use of virtual planning and 3D printing modeling in mandibular reconstruction and compare the operation time and surgical outcome of this technique with conventional method. Between 2014 and 2017, 15 patients underwent vascularized fibula flap mandibular reconstruction using virtual planning and 3D printing modeling. Titanium plates were pre-bent using the models and cutting guides were used for osteotomies. 15 patients who underwent mandibular reconstruction using fibula flap without aid of virtual planning and 3D printing models were selected as control group. The operation time was recorded and compared in two groups. Accuracy of reconstruction was measured by superimposing the preoperative image onto the postoperative image of mandible. The selected bony landmark, distance and angle were measured. The mean total operation time and reconstruction time were 1.60±0.37 and 5.54±0.50 hours in computer-assisted group, respectively; These were 2.58±0.45 and 6.54±0.70 hours in conventional group, respectively. Both operation time and reconstruction time were shorter in computer-assisted group. The difference between the preoperative and postoperative intercondylar distances, intergonial angle distances, anteroposterior distances and gonial angles were 2.92±1.15 and 4.48±1.41mm, 2.93±1.19 and 4.79±1.48mm, 4.31±1.24 and 5.61±1.41mm, 3.85±1.68° and 5.88±2.12° in the computer-assisted and conventional group, respectively. The differences between the preoperative and postoperative mandible is smaller in the computer-assisted group. Virtual planning and 3D printing modeling have the potential to increase mandibular reconstruction accuracy and reduce operation time. we believe that this technology for mandibular reconstruction in selected patients will become a used method and improve the quality of reconstruction.
- Utilizing the nanosecond pulse technique to improve antigen intracellular delivery and presentation to treat tongue squamous cell carcinoma(2018) Gao, Cen; Zhang, Xingxing; Chen, Jian; Zhao, Jiayuan; Liu, Yanmei; Zhang, Jue; Wang, JingTongue squamous cell carcinoma is the most common squamous cell carcinoma of the head and neck. Immunotherapy has great potential in the treatment of tongue squamous cell carcinoma because of its unique advantages. However, the efficacy of immunotherapy is limited by the efficiency of antigen phagocytosis by immune cells. We extracted dendritic cells (DCs) from human peripheral blood. Utilizing a nanosecond pulsed electric field (nsPEF), we deliver the tumour lysate protein into DCs and then incubate the DCs with PBMCs to obtain specific T cells to kill tumour cells. The biosafety of nsPEF was evaluated by the ANNEXIN V-FITC/PI kit. The efficacy of lysate protein delivery was evaluated by flow cytometry. The antitumour efficacy was tested by CCK-8 assay. The nsPEF of the appropriate field strength can significantly improve the phagocytic ability of DCs to tumour lysing proteins and have good biosafety. The tumour cell killing rate of the nsPEF group was higher than the other group (p< 0.05). Utilizing nsPEF to improve the phagocytic and presenting ability of DCs could greatly activate the adaptive immune cells to enhance the immunotherapeutic effect on tongue squamous cell carcinoma.
- Impact of the anatomical location, alcoholism and smoking on the prevalence of advanced oral cancer in Brazil(2018) Bezerra, Natanael-Victor-Furtunato; Leite, Karla-Lorene-de França; de Medeiros, Mariana-Marinho-Davino; Martins, Mariana-Leonel; Cardoso, Andrea-Medeiros-Rodrigues; Alves, Pollianna-Muniz; Padilha, Wilton-Wilney-Nascimento; Cavalcanti, Yuri-WanderleyTo evaluate the prevalence of oral cancer in Brazil according to the clinical stage, anatomical location, alcoholism and smoking. Data referring to 31,217 cases of oral cancer, from 2000 to 2010, were obtained from the Integrator Module of the Hospital Registry of Cancer. Inconsistent data (?non-classified? cases) was eliminated and 21,160 cases were analyzed. The frequency distribution according to clinical stage, anatomical location, alcoholism and smoking was analyzed descriptively and through a binary logistic regression model (?<0.05). The clinical stage (dependent variable) was dichotomized in early stage (I and II) or advanced stage (III and IV). The year of diagnosis, anatomical location and deleterious habits (alcoholism and smoking) were considered independent variables. The most frequent characteristics were: oropharynx location (n=3856, 18.41%), clinical stage IV (n=11924, 56.09%) and combined use of alcohol and tobacco (n=19226; 61.59%). The year 2009 (p<0.01, PR = 1.162, CI-95%=1.053-1.283) and location at the base of tongue (p<0.01, PR = 2.485, CI-95% = 2.182-2.807) presented a higher prevalence ratio for advanced stage oral cancer. The combined use of alcohol and tobacco showed a higher prevalence rate for the advanced clinical stage of cancer (p<0.01, PR =1.449, CI-95%=1.382-1.520) if compared to individuals without habits, or just alcoholics. Higher prevalence of advanced stage of oral cancer is related to the localization at the base of the tongue and to the concomitant use of alcohol and tobacco. Therefore, it can be suggested that all these characteristics lead to a worse prognosis of oral cancer.
- Oral peripheral ameloblastoma : a retrospective series study of 25 cases(2018) Zhang, Xinyu; Tian, Xuerui; Hu, Yongjie; Zhang, Chenping; Wei, Cao; Yang, XiPeripheral ameloblastoma (PA) is a rare and unusual variant of odontogenic tumor, which was described only in isolated case reports in literature. The objective of this study was to investigate the clinical profile, treatment and outcome of PA in a consecutive case series. A total of 25 patients with histologically confirmed PA from 2001 to 2015 were retrospectively reviewed in our institution. Of the 25 patients, 22 males and 3 females were identified (male: female = 7.3:1). The average age was 48.3 years (range 11-81 years) with lingual or palate gingival region being the most common site (76%). The course of disease was less than 6 months in 92.0% (23/25) of all patients (mean, 3.3 months; range, 1-12 months). All patients underwent complete surgical removal of the lesions, and one lesion recurrence occurred during the follow-up period. The clinical profile and outcome of PA from Eastern China were elucidated in this retrospective analysis based on a case series. Our experience may provide some insights into the differential diagnosis and clinical management of PA. The first choice of treatment is surgical excision, which can result in a good prognosis.
- A comparison of the effects of Methylprednisolone Acetate, Sodium Hyaluronate and Tenoxicam in the treatment of non-reducing disc displacement of the temporomandibular joint(2018) Yapici, Günay; Kaya, Göksel ?im?ek; O?ul, HayriThis clinical study aimed to radiologically and clinically compare the effect of intra-articular injection of methylprednisolone, sodium hyaluronate or tenoxicam following arthrocentesis with that of arthrocentesis alone in patients with non-reducing disc displacement. A total of 44 patients radiographically diagnosed with non-reducing disc displacement of the temporomandibular joint (TMJ) were randomly divided into four treatment groups, as follows: Group 1, arthrocentesis alone; Group 2, arthrocentesis plus methylprednisolone acetate; Group 3, arthrocentesis plus sodium hyaluronate; Group 4, arthrocentesis plus tenoxicam. Maximum mouth opening (MMO), lateral movement, pain severity and tenderness of TMJ and muscles of mastication on palpation were measured before treatment and at 1 week and 1, 3 and 6 months after treatment. Disc position, presence or absence of disc reduction, level of effusion, joint movement and joint space were also evaluated using magnetic resonance imaging (MRI) before treatment and 6 months after treatment. No significant differences in treatment success were found among the four groups. MRI findings did not vary significantly among the groups, but pre- and post-operative MRI findings varied significantly within all four groups (p<0.001). According to the data from this study, it may be concluded that either arthrocentesis alone or arthrocentesis with methylprednisolone acetate or sodium hyaluronate or tenoxicam intra-articular injections are similarly effective and promising methods in the treatment of TMJ with non-reducing disc displacement.
- Lichenoid lesions of the upper lip : a retrospective study of 24 cases(2018) Katsoulas, Nikolaos; Tosios, Konstantinos I.; Sklavounou-Andrikopoulou, AlexandraLichenoid lesions of the upper labial mucosa, without other oral or extraoral manifestations seem to be rare. The clinicopathologic features of 24 such cases are presented and the pertinent literature is reviewed. 24 Caucasian patients that clinically presented lichenoid features on the upper labial mucosa, with or without lichenoid lesions on the adjacent gingiva, were included in the study. Clinical features were extracted from the patients? records, while dental plaque/calculus accumulation and composite resin restorations of the adjacent teeth were recorded. Four cases where an incisional biopsy was performed were further evaluated. There were 8 males and 16 females, with a mean age of 62.7 years. 64.2% were under hypertensive therapy. In 13 cases gingival involvement was noticed, 16 cases exhibited calculus deposition, while 6 cases presented with composite resin fillings of the adjacent teeth. In 4 cases an incisional biopsy was performed showing features of lichenoid reaction. In 37.5% significant improvement was observed after topical treatment with corticosteroids and antimicrobial agents. Lichenoid lesions of the upper lip may represent a distinct variety of oral lichenoid lesions, but as the number of cases reported so far is too small for definite conclusions on pathogenesis and management to be made, a long-term follow-up is mandatory.
- Is arthrocentesis of temporomandibular joint with corticosteroids beneficial? A systematic review(2018) Davoudi, Amin; Khaki, Hossein; Mohammadi, Iman; Daneshmand, Mehran; Tamizifar, Alireza; Bigdelou, Meysam; Ansaripoor, FarzinTemporomandibular disorders (TMDs) are musculoskeletal conditions that can inhibit the normal function of temporomandibular joints (TMJs) and affect the patient?s quality of life, negatively. Arthrocentesis (AC) is a minimally invasive surgical procedure used for treating TMDs. The aim of present paper is to evaluate the advantages of administrating corticosteroid (CS) during AC by reviewing high quality released articles. After initial search, a total of 2067 articles were included into the study. Finally, 7 studies were reliable enough in methodology and randomization to be included into the study. All of the observed studies showed improvements in jaw functions and pain relief with no statistical differences in both AC and control groups. One study reported painless maximum incisal opening in CS group than the control group. Based on available RCTs, the AC of TMJ with CS seems to result in similar findings to other therapeutic drugs, with no significant differences.
