Within the limits of this study, we concluded that the in Brazilian patients studied, the GPF location was more closely related to third molar. Therefore, whenever the third molar is erupted, it could be used as landmark for successful GPN block anesthesia. Moreover, harvesting palatal mucosa graft around the third molar should be done cautiously to prevent damage to the GPF vascular-nerve complex.

Objective: To determine how the diagnosis may or may not be influenced by cone-beam computed tomography (CBCT), comparing the diagnostic hypotheses obtained using images of panoramic radiographs and CBCT in cases of ameloblastoma, odontogenic keratocyst, and dentigerous cyst. Study Design: Five cases were selected for each lesion. Panoramic radiographs and CBCT scans were analyzed by 15 dentists for the formulation of the diagnostic hypotheses. Two observers performed the analyses and measurement of qualitative and quantitative features of the lesions evaluated in the CBCT. Results: There was no statistically significant difference in correct diagnostic average between panoramic radiography and CBCT, but there was a significant difference in correct diagnostic average in the diagnosis of ameloblastoma using CBCT compared to panoramic radiography. Master's and PhD-level observers had greater correct diagnostic average in the diagnosis of odontogenic keratocyst using panoramic radiograph compared to specialists, with a significant difference. Conclusion: Cone-beam computed tomography images revealed that the ameloblastomas were greater in size and expansion compared to the odontogenic keratocyst and the dentigerous cysts. Ameloblastomas showed a higher incidence of multiloculated aspects compared to odontogenic keratocyst and dentigerous cysts. There were no differences between quantitative and qualitative features of odontogenic keratocyst and dentigerous cysts.

Canalis sinuosus (CS) is a neurovascular canal that corresponds to a small branch of the infraorbital canal. It contains the anterior superior alveolar nerve and vessels, supplying the anterior maxilla. Despite having been described 81 years ago, CS is not recognized by many dental practitioners and may be the cause of unintended injuries during dental procedures. The aims of this study are to report a case of a patient who suffered pain due to exposure of the CS, to provide a comprehensive review of other CS cases that were challenging to diagnose, and to propose guidelines for preoperative examination of patients undergoing surgical procedures in the anterior maxilla. The review of the literature revealed six cases, in addition to the one presented here, of unintended or potential damage to CS. Five out of seven cases were related to dental implant placement and resulted in postoperative pain and/or paresthesia. The dental implant was removed in 4 out of the 5 cases. This study reinforces the importance of awareness of CS by dental practitioners and provides a protocol for the preoperative examination of the patient to prevent avoidable injuries to CS.

Introduction Canalis sinuosus (CS) is a neurovascular canal that corresponds to a small branch of the infraorbital canal. This study aimed at assessing the knowledge and detection performance of CS amongst dentists and dental students. Materials and Methods Four‐hundred and five dentists and dental students answered a questionnaire with three parts: 1. Socio‐demographical; 2. Clinical cases with cone‐ beam computed tomography (CBCT) sections showing CS and 3. Previous knowledge about CS. The chi‐squared test and Spearman's correlation test were used to compare results as appropriate. p‐values below .05 were considered statistically significant. Results Most participants did not identify CS in any CBCT. There was an association between the number of correct answers and dental specialties. Most individuals had not learned about CS previously. There was an association between past knowledge of CS and gender, highest academic degree, working environment, dental specialty and number of correct answers but not with age or experience in Dentistry. Conclusion This study suggests that most dentists are not aware about CS and do not know how to diagnose it. Previous knowledge about CS positively influenced its identification in CBCT.

BackgroundThe use of monoethanolamine oleate 5% is effective for the treatment of vascular malformations with low blood flow.ObjectivesTo report a case series of vascular malformations in the mouth and oral cavity treated with monoethanolamine oleate 5%.MethodsA retrospective descriptive study was performed in electronic patient charts covering seven years. Patient demographics, diagnostic resources, lesion site, size, and number of applications of monoethanolamine oleate 5% were collected.ResultsA total of 21 vascular malformations were recorded, located mostly on the lower lip (52.3%) and resolved in a single application in 14 patients. The authors found 19 patients treated with sclerotherapy. Thirteen were women and six were men, with a mean age of 61 years.Study limitationSmall sample size.ConclusionsSclerotherapy is an effective treatment for vascular malformations of the lips and oral cavity, with resolution after only one or two applications (n = 16).

ResumoIntrodução: O avanço da tecnologia permitiu que a Radiologia Odontológica evoluísse para o sistema digital, eliminando o processamento químico das radiografias e otimizando o tempo clínico. Todavia, o clínico necessita manipular cada sistema digital, considerando as similaridades e diferenças para o melhor uso em clínica. Objetivo: Discutir as técnicas dos dois tipos de sensores digitais disponíveis no Setor de Radiologia da FOA-UNESP. Material e Método: Os dois sistemas de imagem digital, placa de fósforo fotoestimulável (PSP) e sensor sólido (CMOS), foram comparados para observação de suas similaridades desde o momento do posicionamento no paciente, processamento da imagem até o armazenamento, e também considerando o custo da implantação de cada sistema. Resultados: Os posicionadores para o sistema CMOS são diferentes dos utilizados nas radiografias convencionais. O processamento da imagem das placas de fósforo necessita de um aparelho de escaneamento adicional de alto custo, e é passível de erro durante a manipulação. Já o sistema CMOS, tem a imagem adquirida imediata e concomitantemente ao disparo do aparelho de raios X, mas necessita de maior cuidado para a inserção do conjunto posicionador-sensor no paciente. Conclusão: A placa de fósforo representa o sistema de implantação de maior custo, mas é o sistema mais confortável para o paciente e mais semelhante, em relação ao posicionamento, às radiografias com filme. O sistema CMOS é mais barato e a visualização da imagem é imediata. Ambos permitem que a imagem seja editada e armazenada em computadores. Descritores: Radiografia; Radiografia Dentária Digital; Radiografia Dentária. AbstractIntroduction: The technology allowed Dental Radiology to evolve into the digital system, eliminating the chemical processing of radiographs and optimizing clinical time. However, the clinician needs to manipulate each digital system, in order to consider the similarities and the differences for the best clinical use. Objective: To discuss the techniques of the two types of digital sensors available in the Radiology Department of FOA-UNESP. Material and Method: The two systems of digital image, photosensitive phosphor plate (PSP) and solid sensor (CMOS), were compared to observe their similarities from the time of patient positionin unitl the image processing to storage, and also considering the cost of deploying each system. Results: The positioners for the CMOS system are different from those used in conventional radiographs. The image processing of the phosphor plates requires an additional expensive scanning device and is susceptible to error during manipulation. On the other hand, the CMOS system has the image acquired immediately and concomitantly with the X-ray device firing, but more care is needed to insert the positioner-sensor assembly into the patient. Conclusion: The phosphor plate represents the costliest implantation system, but it is the most comfortable system for the patient and more similar, in relation to the positioning, to the film X-rays. The CMOS sy...

ABSTRACT:Tuberous sclerosis is an autosomal dominant neurocutaneous syndrome, which may involve multiple organ systems and shows highly variable clinical manifestations. Oral manifestations, including lesions on hard tissues, enamel hypoplasia and gingival hyperplasia have been previously described. We report a case of 25-year-old woman with this syndrome presenting multiple fibrous nodules on the buccal mucosa and lips. Awareness of the different oral manifestations of tuberous sclerosis is important to ensure appropriate diagnosis and treatment.
