A presente pesquisa teve como objetivo comparar os valores médios normais das angulações mesiodistais dentárias, propostos por Ursi em 1989, com as angulações mesiodistais de caninos, pré-molares e molares inferiores em indivíduos com e sem a presença dos terceiros molares inferiores. Além disso, foram comparados os valores das angulações mesiodistais de caninos, pré-molares e molares inferiores nestas duas situações. Para a realização deste trabalho, foram utilizadas 40 radiografias ortopantomográficas de indivíduos de ambos os gêneros que não receberam tratamento ortodôntico, divididos em dois grupos: Grupo I, constituído por 20 radiografias que não apresentavam os terceiros molares inferiores e Grupo II, formado por 20 radiografias com os terceiros molares inferiores presentes. Para realização das mensurações, uma folha de papel de acetato Ultraphan foi adaptada sobre cada radiografia, permitindo o traçado do contorno externo da imagem da mandíbula, forames mentonianos, linha intermentoniana, contorno de caninos, pré-molares e molares inferiores e longos eixos dos dentes. Os desenhos anatômicos foram digitalizados e os ângulos formados pela intersecção dos longos eixos dos dentes com a linha intermentoniana foram medidos pelo programa AutoCAD 2000. A análise dos resultados e a análise estatística permitiram concluir que ambos os Grupos exibiram pré-molares e molares inferiores mais angulados em sentido mesial quando comparados à oclusão normal. Por outro lado, a angulação mesiodistal de caninos inferiores mostrou-se semelhante àquela apresentada em casos de oclusão normal. Os dois Grupos, quando comparados entre si, exibiram valores angulares dos caninos, pré-molares e molares inferiores semelhantes, de modo que a presença dos terceiros molares não exerceu influência sobre estas angulações mesiodistais dentárias.
The present research had as objective compare the normal medium values of the mesiodistal axial angulation, proposed by Ursi in 1989, with the mesiodistal axial angulation of canine teeth, premolar and inferior molars in individuals with and without the presence of the third inferior molars. Besides, the values of the mesiodistal axial angulation of canine, premolar and inferior molars were compared in these two situations. For the accomplishment of this work, they were used 40 panoramic x-rays from individuals of both sexes that didn't receive orthodontic treatment, divided in two groups: Group I, constituted by 20 x-rays that didn't present the third inferior molars and Group II, formed by 20 x-rays with the presence of the third inferior molars. For accomplishment of the measurements, a leaf of paper of acetate Ultraphan was adapted on each x-ray, allowing the plan of the mandibles' external outline, mental foramen, reference line passing through the centers of the mental foramens, outline of canine, premolar and inferior molars and long axes of these teeth. The anatomical drawings' digitization allowed the measurement of the angles formed by the encounter of the long axes of the teeth with the reference line through AutoCAD 2000 program. The results analysis and the statistical analysis allowed concluding that both Groups exhibited inferior premolar and molars more angulated in mesial direction when compared to the normal occlusion. On the other hand, the mesiodistal axial angulation of inferior canine teeth was shown similar that presented in cases of normal occlusion. The two Groups, when compared amongst themselves, exhibited similar angular values of the canine teeth, premolar and inferior molars, so that the presence of the third molars didn't exercise influence on these dental angulations.

Повний текст джерелаAccurate determination of working length during endodontic therapy is critical in achieving a predictable and successful outcome. Working length is determined by the use of electronic apex locators, tactile perception, knowledge of average tooth lengths and dental radiography. Due to the increasing use of digital radiography in clinical practice, a comparison with conventional film in working length determination is justified. The purpose of this study is to determine if there is a difference between Schick digital radiography and Kodak Ultra-speed film in the accurate determination of working lengths when vertical angulation of the object is variable. Twelve teeth with #15 K-flex files at varying known lengths from the anatomical apex were mounted in a resin-plaster mix to simulate bone density. A mounting jig for the standardization of projection geometries allowed for exact changes in vertical angulation as it related to the object (tooth) and the film/sensor. Each tooth was imaged using Schick CDR and Kodak Ultra-speed film at varying angles with a consistent source-film distance and exposure time. Four dental professionals examined the images and films independently and measured the distance from the tip of the file to radiographic apex and recorded their results. The error in working length was calculated as the observed value minus the known working length for each tooth type. A mixed-effects, full-factorial analysis of variance (ANOVA) model was used to model the error in working length. Included in the ANOVA model were fixed effects for type of image, vertical angulation, and the interaction of angle and film type. Tooth type and examiner were included in the model as random effects assuming a compound symmetry covariance structure. The repeatability of each examiner, for each film type, was assessed by estimating the intra-class correlation coefficient (ICC). The ICC was determined when 12 randomly selected images and radiographs were reevaluated 10 days after initial measurements. The repeatability of each examiner for Schick CDR was good with ICCs ranging from 0.67 to 1.0. Repeatability for the conventional film was poor with ICCs varying from -0.29 to 0.55. We found the error in the working length was not significantly different between film types (p = 0.402). After adjusting for angle, we found that error in the working length from the digital image was only 0.02 mm greater (95-percent CI: -0.03, 0.06) than the conventional film. Furthermore, there was not a significant difference among the angles (p = 0.246) nor in the interaction of image type with angle (p = 0.149). Based on the results of our study, we conclude that there is not a statistically significant difference in determining working length between Schick CDR and Kodak Ektaspeed film when vertical angulation is modified.

Повний текст джерелаIntroduction: The radiographic evaluation of the presence, position and developmental stage of the third molar can be useful for predicting the need of a germectomy. Objective: The aim of this study is to radiographically analyze the third molar tooth germ, describing its presence/absence and mineralization stage (Nolla’s developmental stages) and classify them according to their orientation (Winter’s classification) and angulation. Methodology: We conducted a cross-sectional observational analytical study by analysing 540 panoramic radiographs of patients with ages between 4 and 21 years old from ICS-Viseu’s University Dental Clinic. Results: In all third molars tooth germ Nolla’s stage 0 is observed in the age group up to 9 years and increases until the age group of 16-21 years. The evolution of upper third molars tooth germ begins earlier than that of the lower third molars tooth germ. The most common orientation in the upper third molars tooth germ was the vertical, then the distal. In the lower third molars tooth germ, the most common orientation were mesial and vertical. When using the angle formed between the occlusal plane of the third molar tooth germ and the long axis of the second molar, the average angle of the tooth 38 was 69º while the one of the tooth 48 was 66º. The average angle by angle formed between the long axis of third molar tooth germ and the long axis of the second molar, was 21º for the tooth 38 and 20º for the tooth 48. Conclusion: The evaluation of the need for germectomy should be considered for each patient with consistent criteria and methodologies for angulation and orientation of the third molar tooth germ.
