- Software applied to oral implantology : update(2008) Rubio Serrano, Minerva; Albalat Estela, Salvador; Peñarrocha Diago, María; Peñarrocha Diago, MiguelSoftware in combination with imaging techniques is used increasingly for diagnosis, planning and treatment in oral implantology. Computer-aided surgery allows a great accuracy in implant positioning to be obtained, taking advantage of the amount of bone available and facilitating minimally invasive surgery. It is a significant aid in determining implant number, location, angle and characteristics. A CT with a radiographic template positioned in the mouth is made for the patient. Data are stored on a CD in DICOM 3 format and then introduced in the computer where implant treatment will be planned, using the chosen software. Navigation improves surgical accuracy through the aid of software based on the images captured from CT or MRI and a surgical instrument tracking system. Infrared light-emitting diodes are connected to rotatory instruments and to the patient?s template. Information is collected by special-purpose cameras, allowing the procedure to be viewed in real time on a monitor. It is useful in situations where an exact implantation is demanded, such as anatomical limitations, little space, atrophic maxillae, sinus lifts or zygomatic implants. Articles reviewed agree in emphasizing the reliability and accuracy of the planning and computer-assisted navigation systems available in the market. Nevertheless, many applications are still in the development phase.
- Benign fibro-osseous lesions of the maxillas : analysis of 11 cases(2008) Vegas Bustamante, Erika; Gargallo Albiol, Jordi; Berini Aytés, Leonardo; Gay Escoda, CosmeIntroduction: A study is made of the principal characteristics of the oral lesions biopsied in our Service of Oral Surgery and histologically diagnosed as corresponding to fibro-osseous lesions of the maxillas. Patients and methods: A retrospective review was made of all the biopsies made in a Service of Oral Surgery between 1996 and 2003. The reason for consultation was analyzed, along with patient age, sex, clinical and radiological characteristics, tentative diagnosis, histological diagnosis and treatment provided. Results: A total of 1238 biopsies were performed during the study period. Of these, only 11 corresponded to benign fibro-osseous lesions (7 women and 4 men). The mean patient age was 44 years (range 19-72 years). The most frequent location was the mandible (8 of the cases). In 7 patients the lesions constituted casual radiological findings; 4 presented bulging of the vestibular cortical bone, though only one of them reported pain. The histological diagnoses comprised 7 cemento-ossifying fibromas and 4 fibrous dysplasias. In 9 cases surgical resection was carried out, while in one case an incisional biopsy was performed, and in the remaining case curettage was decided. Discussion: These lesions are more frequent in women than in men, and the age at presentation is variable. In terms of lesion location, fibrous dysplasia is more common in the upper maxilla, while cemento-ossifying fibroma is more frequently found in the mandible. The diagnosis of such lesions is established upon contrasting the data obtained from the anamnesis, physical examination, the radiological characteristics, the intraoperative findings and the histological study, since both disorders have similar clinical and histological features ? despite the fact that they constitute distinct disease conditions.
- Local flap reconstruction of large scalp defects(2008) García del Campo, José Antonio; García de Marcos, J.A.; Castillo Pardo de Vera, José Luis del; García de Marcos, M.J.Scalp defects can have a number of origins, and their repair is dependent upon their location, size and depth. In the case of the scalp, the repair of even small defects is complicated. Local flaps are the reference for the reconstruction of such defects. Knowledge of scalp anatomy is essential for preparing these flaps, which must be based on one or two vascular pedicles to afford a large rotation angle ? thereby facilitating closure of the defect. The parietal zone is the location offering the greatest flap mobilization possibilities. We present a case involving the repair of a major pericranial frontoparietal scalp defect. A local transverse posterior transpositioning scalp flap was raised with the posterior auricular and occipital arteries as vascular pedicle. Following repositioning of the flap, a free partial-thickness skin graft from the thigh was used to cover the donor zone. A review is provided of the different techniques for the reconstruction of large scalp defects.
- Use of mineral trioxide aggregrate in the non-surgical repair of perforating invasive cervical resorption(2008) Park, Jun-Beom; Lee, Jeong HeonMineral trioxide aggregate (MTA) has shown potential as a repair material for perforations. This clinical case demonstrates that when MTA was used as a repair material for root perforation due to invasive cervical resorption, the tooth was well in function for 27 months. Both clinical and radiographic follow-up showed a stable condition without any probing defect, ongoing root resorption, or apical pathosis.
- Intraosseous foreign-body granuloma in the mandible subsequent to a 20-year-old work-related accident(2008) Silveira, Vanessa Ávila Sarmento; Carmo, Elaine Dias do; Colombo, Carlos Eduardo Dias; Cavalcante, Ana Sueli Rodrigues; Carvalho, Yasmin RodarteThe purpose of this article was to describe the clinical and microscopic features of an intraosseous foreign-body granuloma in the mandible that developed after the traumatic implantation of metal fragments during a work-related accident. A 65-year-old male patient had a severe pain in the body of mandible. Clinical examination showed facial asymmetry and a scar, extending to the left mental region. Intraoral examination revealed a soft mass involving the left alveolar bone with normal appearance of the mucosa surface. Panoramic radiographs showed a radiolucent lesion along the mandible extending from the central incisive to the first molar. Computed tomography revealed an osteolytic mass in the same area. His medical history included a work-related accident twenty years prior to evaluation. During the biopsy an important amount of bright metal-like pieces surrounded by soft tissue were found. A microscopic examination showed a foreign body associated with an aggregation of multinucleated giant cells. The final diagnosis was a foreign body granuloma. Even though foreign-body granulomas in the mandible are rare lesions, dentists should be familiar with their features and include them in the differential diagnosis of tissue masses.
- Prevalence of smoking among dentists in Catalonia - Spain (2006) : literature review of smoking cessation practices in the dental office(2008) Casals Peidró, Elías; Otero Romero, Susana; Cuenca, EmiliObjective: The objective of this study was to collect data on the prevalence of smokers among Catalonian dentists (by age and sex) and compare them with existing data on the general population, doctors, registered nurses and pharmacists. The overall prevalence of smokers in Catalonia (2006) was 34.5% of men and 24.3% of women. Data available on the prevalence of smoking among doctors (26.3% men and 22.1% women), pharmacists (19.8% men and 20.6% women) and registered nurses (34.1% men and 35.3% women) relates to the year 2002. Study design: In September 2006, Catalonian dentists (n=3,799) were asked about their habits in relation to tobacco in a self-administered questionnaire, on use and opinions with respect to dental amalgam. Five hundred and seventynine questionnaires were received, of which 538 answered the question on smoking (14.2% of the sample universe). Results: The prevalence of smokers among dentists is lower (24.9% of men and 18.4% of women) than in the general population and other healthcare professionals. In dentists in the age group between 25 and 34 years, the prevalence was 26.1% in men and 14.9% in women, while the prevalence in this age group in the general population was 43.6% and 37.1%, respectively. Conclusion: Catalonian dentists have a much lower prevalence of tobacco use than the general population and lower even than other healthcare professionals. Given that non-smoking healthcare professionals have better awareness for providing recommendations for smoking prevention and cessation, Catalonian dentists may be a valid group for performing this task for which there is scientific evidence.
- Analysis of the histopathological artifacts in punch biopsies of the normal oral mucosa(2008) Camacho Alonso, Fabio; López Jornet, María Pía; Jiménez Torres, María José; Orduña Domingo, AlbinaObjectives: To study the most frequent artifacts of punch biopsies of the healthy oral mucosa, distinguishing between those attributable to the surgical technique and those resulting from sample processing in the laboratory. Study design: A total of 186 samples of oral mucosa (dorsal lingual mucosa) were obtained from 186 adult albino rats by the experienced oral surgeons, evaluating the presence of artifacts attributable to the surgical technique (crush, splits, fragmentation, pseudocysts and haemorrhage) and those attributable to sample processing in the laboratory (orientation). Results: The distribution of artifacts attributable to the surgical procedure was as follows: crush 16.67%, splits 0%, fragmentation 0%, pseudocysts 1.08% and hemorrhage 0%. The artifacts corresponding to sample processing in the laboratory (orientation) represented 37.63%. Conclusions: The present study shows use of the punch for obtaining biopsies of the healthy oral mucosa to produce few artifacts. In addition, good or poor orientation of the samples is not attributable to the surgical technique but to processing of the samples in the laboratory.
- Analgesic action of laser therapy (LLLT) in an animal model(2008) Pozza, Daniel Humberto; Fregapani, Patrícia Wehmeyer; Weber, João Batista Blessmann; Oliveira, Marilia Gerhardt de; de Oliveira, Marcos André Matos; Ribeiro-Neto, Nelson; de Macedo Sobrinho, João BatistaObjectives: To evaluate the analgesic effect of laser therapy on healthy tissue of mice. Study design: Forty-five animals were divided in three groups of 15: A ? infrared laser irradiation (830 nm, Kondortech®, São Carlos, SP, Brazil); B ? red laser irradiation (660 nm, Kondortech®, São Carlos, SP, Brazil); C ? sham irradiation with laser unit off. After laser application, the mice remained immobilized for the injection of 30 µl of 2% formalin in the plantar pad of the irradiated hind paw. The time that the mouse kept the hind paw lifted was measured at 5 min intervals for 30 minutes. Results: Results showed statistically significant differences comparing the control group with the infrared laser group at 5, 20, 25 and 30 accumulated minutes, and with the red laser group at all time points. The analysis of partial times, at each 5 minutes, showed statistically significant differences between the control and the laser groups up to 20 minutes. Conclusions: Laser therapy had an analgesic effect and red laser had the best results.
- Beckwith Wiedemann Syndrome : presentation of a case report(2008) Narea Matamala, Gonzalo; Fernández Toro, María de los Ángeles; Villalabeitía Ugarte, Elías; Landaeta Mendoza, MirthaBeckwith Wiedemann Syndrome (BWS) is a rare congenital disease of low prevalence. However, it presents a high prevalence within the genetic pathologies of overgrowth. This syndrome presents typical manifestations such as macroglossia, macrosomy at birth, omphalocele and defects of the anterior abdominal wall. Its origin is known to be genetic, but its mechanism of generation is not clear. This syndrome has been the object of wide studies since investigators have established a relationship between the methods of assisted fertilization (assisted reproduction treatment, ART) and its appearance. Currently, research is oriented towards the improvement of the prenatal diagnostic techniques, which would allow a preparation of the multidisciplinary medical team to treat the pathologies with which these patients are born. Next we present the case of a 1 year-old child who consults this service with a diagnosis of macroglossia associated with BWS.
- Dental management of oral self-mutilation in neurological patients : a case of congenital insensitivity to pain with anhidrosis(2008) Romero Maroto, Martín; Simón de las Heras, Rogelio; García Recuero, Ignacio Ismael; Romance García, AnaHereditary sensory and autonomic neuropathy type IV is a rare disease characterized by fever episodes, mental retardation of different intensity, recurrent episodes of fever secondary to anhidrosis, little or no perspiration and congenital insensitivity to pain. Oral self-mutilation is also a characteristic sign. In this article, we present the case of an infant, aged 22 months, who showed these clinical characteristics and was treated with a dental device to prevent the patient from injuring her tongue. This device consisted of two acrylic splints joined at the back in the posterior sector, it provided an anterior open bite and allowed the infant to breathe through her mouth. The lesions of the patient had improved after using the device but the patient died due to the medical problem. Neuropathies treatment is a great challenge for medical teams.Dentists should form part ot these teams because of the bucal implications that may appear. Different appliances can be designed in order to solve the special problems each case may present.
- Pycnodysostosis : a report of 3 clinical cases(2008) Alves Pereira, Daniela; Berini Aytés, Leonardo; Gay Escoda, CosmePycnodysostosis is a rare clinical entity, first described in 1962 by Maroteaux and Lamy. It is a genetic disorder, usually diagnosed at an early age. However, the diagnosis is sometimes late, made as a result of bone fracture, given the severe bone fragility resulting from increased bone density. Oral and maxillofacial manifestations of this disease are very clear. The head is usually large, the nose beaked, the mandibular angle obtuse, and both maxilla and mandible hypoplastic. Dental abnormalities and impaction are observed, as well as alterations in eruption and frequent dental crowding. The differential diagnosis is established with osteopetrosis, cleidocranial dysplasia and idiopathic acro-osteolysis. This article reviews the clinical and radiographic characteristics of pycnodysostosis based on three clinical cases of patients with this disease.
- Infected lingual osseous choristoma : report of a case and review of the literature(2008) Andressakis, Dionysios D.; Pavlakis, Athanasios G.; Chrysomali, Evanthia; Rapidis, AlexanderOsseous choristoma is a rare, benign lesion of the oral cavity occurring usually in the tongue. It appears as a tumorous mass of normal bony structure with mature cells in an ectopic position. The case of a 72 years Caucasian male is presented and analyzed along with 52 similar cases reported in the English literature between 1967 and 2007. Lingual choristoma shows a female predilection, whereas the commonest anatomic location is the posterior third of the tongue, occurring at or close to the foramen caecum and the circumvallate papillae. Histologically the lesions show signs of a well-circumscribed mass of vital bone located under the surface oral epithelium. Some lesions represent developmental malformations, whereas others may be reactive lesions after trauma or chronic irritation. Treatment of lingual osseous choristoma consists of simple excision.
- Pemphigus vulgaris in oral cavity : clinical analysis of 71 cases(2008) Shamim, Thorakkal; Varghese, Vengal Ipe; Shameena, Pallikandi Maliyekkal; Sudha, SivasankarObjective: The purpose of the study was to evaluate the clinical presentation of pemphigus vulgaris in the oral cavity. Study design: A retrospective study of 71 cases of pemphigus vulgaris obtained over a period of 7 years from 1st January 2001 to 31st December 2007 in the Department of Oral Pathology, Government Dental College and Department of Dermatology, Government Medical College, Calicut was designed. Clinical details such as age, sex, intraoral distribution, extent of oral lesions, oral presentation, duration, oral involvement (whether primary or secondary) and mode of onset were noted from the files of corresponding Departments. Results: In about 53.52% of cases, the oral cavity was the primary site of involvement. The mean age was 42.73 years and male: female ratio was 1:1.73. The most commonly affected sites were the buccal mucosa and the palate. The disease began with generalized lesions rather than localized lesions. All cases presented as ulcers or erosions. Conclusion: Although minor differences were noted, the results of this study are in relatively good agreement with the literature with regard to the age, gender, and initial presentation of pemphigus vulgaris.
- Malignant mental nerve neuropathy : systematic review(2008) Galán Gil, Sonica; Peñarrocha Diago, María; Peñarrocha Diago, MiguelMalignant mental neuropathy (MMN) is a neurological manifestation of cancer, characterized by the presence of hypoesthesia or anesthesia restricted to the territory of the mental branch of the mandibular nerve. A systematic review of the literature has been made on MMN, analyzing the etiology, pathogeny, clinical characteristics, complementary tests and the prognosis. Sixteen studies, providing 136 cases were selected. Breast cancer and lymphomas were the most frequently associated malignant diseases. The most frequent pathogenic mechanisms producing neurological involvement were: peripherally, mandibular lesions; and centrally, tumors at the base of the cranium. Regarding clinical characteristics, manifestation of MMN was the primary symptom of malignant disease in 27.7% of cases, and a first symptom of recurrence in 37.7%. The group of selected studies included 50 orthopantomographs, 9 mandibular computed tomographies and 50 radiographic examinations of the cranial region. The most affected region was the mandible. The appearance of MMN is an ominous prognosis for the progression of the disease, with a mortality of 78.5% within a mean of 6.9 months.
