Diagnóstico radiográfico diferencial das reabsorções radiculares internas e externas entre especialistas em endodontia e clínicos gerais

Objectives: The objective of this study was to evaluate the ability of endodontists and general practioners to perform the differential radiographic diagnosis between internal and external root resorptions, using digitized periapical radiographs. Methods: Thirty periapical radiographic images of external and internal resorption were selected. The evaluators were comprised of 15 endodontists and 29 general practitioners who answered a questionnaire with the following question: “What type of resorption in the following radiographics do you diagnose?” (1) Inflammatory external root resorption. (2) Internal root resorption. Statistical analysis was performed based on the Mann-Whitney test, with significance level of 5%. Results: There was no statistically significant difference in the percentage of correct answers from specialists in endodontics and general practitioners. Conclusions: Both groups demonstrated satisfactory skill in the radiographic interpretation of internal and external resorption and there was a higher percentage of correct diagnosis of internal resorption than the external.

Definição e abordagem de currículo: exame de um curso de formação de professores para a educação não formal em ONGs

This article presents a research aimed to analyze the approach and the definition of guiding curriculum of teacher training for work in the non-formal education in non-governmental organizations (NGOs). We opted for a qualitative approach and case study of Te- acher Training Course for NGOs, developed by Ong São Paulo-SP. The research instruments were: analysis of documents of the cou- rse, interviews with trainers and coordinator and literature review. In this course, curriculum is defined as a path to be followed by students and instructors and the coordinator of the subjects studied. We adopted the so-called Integrated Curriculum, in which teaching occurs by the study of problem situations and integrators of learning projects. At the end, we suggest improving the course and following that information, it is hoped, one will support the production of fur- ther comparative research.

Estudo da erupção dos dentes caninos, primeiros e segundos premolares dos lados direito e esquerdo, pelo método radiográfico

The tooth eruption have been studied for many years about the knowledge of its variations. From these variations the difference between the eruption of the superior and inferior archs, and also the right and left sides have been poorly analysed. The author compared the alveolar eruption of the permanents canines, first and second premolars between the right and left sides of the superior and inferior archs, from 7 and 11 years of age, in males and females, by radiographic method. By the Discipline of Radiology of the Diagnosis and surgery Departament of the School of Dentistry of São José dos Campos - UNESP, observed that: there is early eruption in female; the alveolar eruption sequence in maxillar and mandibular was: first premolar, second premolar e canino. There wasn't statiscally significant difference of the alveolar eruption between the right and left sides of maxillar and mandibular archs

Avaliação da perda óssea alveolar em pacientes encaminhados à especialista em periodontia: estudo radiográfico

The aim of this study was to evaluate the mean of alveolar bone loss (%) in radiographies of patients referred to specialist for periodontal treatment. Full mouth series of periapical radiographies (paralelism technique) were used. A total of 9808 proximal surfaces in 4804 teeth of 213 patients (90 males and 123 females), mean age, 44.3 years, were assessed. The alveolar bone loss was measured in relation to root lenght expressed as an average similar to Schei 's technique (1959) without the use of ruler. The references used were the distances cement-enamel juntion (CEJ) - alveolar crest (AC) and CEJ- dental apex taken with a digimatic caliper. The results showed that the mean values of alveolar bone loss (%ABL) was 22.39%. Men showed higher mean values of %ABL than women; the %ABL increased with the age, but the difference among age groups was no statistical significant (p>0.05); the mean values of %ABL of distal surfaces was higher than mesial surfaces (p<0.01), ríght quadrants exhibited higher %ABL values than left quadrants (p<0.01); maxillary sites showed mean values of %ABL higher than mandibular sites; the highest mean values of %ABL was found in molar group, followed by incisor groups, and premolar group; the canine group exhibited lower mean values of %ABL; the differences among the groups was considered statitistically significant (p<0.01). lt was suggested the usage of this technique in the dentistry offices and radiological services for the patient 's documentation and assortment and for later comparison about alveolar bone level

Estudo da assimetria da fossa mandibular, em crânios secos de crianças pelo método radiográfico

The Temporomandibular Joint is a noble structure of the complex mandibular, a lot of research was conducted on the to signs and symptoms of the alterations that attack those structures. ln spite of the high incidence of the DTM in children, there's little knowledge about it, wich makes difficult the treatment Desorders Craniomandibulares (DCM) or Desorders Temporomandibulars (DTM). The Temporomandibular Joint is composed basically by three elements: bones, muscles and disk, in relation to bony part, we have the fossae mandibular that is part of the temporary bone and wich houses the condyle mandibular, accomplishing the articulation among the cranium and the jaw (it leaves piece of furniture of the articulation). Our intention in that work was of verifying a possible asymmetry of the fossae mandibular on the left side and of the right side in relation to two straight line: a straight line that coincided with the plane medium sagittal and another perpendicular straight line to the plan medium sagittal. Analyzing, the fossae mandibular in 91 dry craniums of children, with age varying between four months of life intrauterina and five years, in x-rays in that the incidence was cranium-flow, we could end that: in spite of we find statistical significance in relation to that asymmetry, clinic cannot affirm that interferences on occlusion exists for that asymmetry

Estudo radiográfico de terceiros molares inferiores retidos e parcialmente irrompidos e revisão de literatuda

Introduction: Pathology associated with retained or partially erupted teeth are common in the general population. Objective: the aim was to evaluate the measurement of pericoronal space of retained third molars and partially erupted teeth in panoramic radiographs. Method: a retrospective study was carried on on the frequency of tooth retention and the problems it can cause in 107 radiographs of patients where the width was measured to verify the presence or absence of diseases associated with the involved teeth. Results: in the 107 panoramic radiographs analyzed the most frequent measurement was of 1.0 mm with 32.71% of cases followed by 2.0 mm with 29.91% of cases. Conclusion: The measurement of the pericoronal sapce of retained third molars and partially retained through its greatest width is in a practical and effective technique for application in routine clinical practice, which suggests the presence or absence of eraly odontogenic pathology

A proporção de plasma rico em plaquetas/enxerto ósseo autógeno pode influenciar o reparo ósseo de defeito de tamanho crítico: estudo radiográfico em calvária de ratos

Introduction: It has been suggested that bone grafts combined with platelet rich plasma (PRP) present greater density than bone grafts without PRP after healing process. However, this result may depend on proportion PRP/autogenous bone (AB) graft used. Objective: The purpose of this study was to analyze radiographically the influence of the proportion PRP/particulate autogenous bone (AB) graft on bone healing in surgically created criticalsize defects (CSD) in rat calvaria. Material and method: 50 rats were divided into 5 groups: C, AB, AB/PRP-50, AB/PRP-100 and AB/PRP-150. A 5 mm diameter CSD was created in the calvarium of each animal. In Group C the defect was filled by blood clot only. In Group AB the defect was filled with 0.01 mL of AB graft. In groups AB/ RP-50, AB/PRP-100 and AB/PRP-150 the defects were filled with 0.01 mL of AB graft combined with 50, 100 and 150 µL of PRP, respectively. All animals were euthanized at 30 days post-operative. Standardized radiographic images of the rat calvaria were obtained using Digora System (Soredex, Finland). The images were evaluated by three examiners using scores that indicated the percentage of radiopacity of the defect. The obtained data were subjected to statistical analysis (Kruskal-Wallis test, p < 0.05). Result: Group C presented radiopacity significantly lower than groups AB, AB/PRP-50, AB/PRP-100 and AB/PRP-150. Group AB/PRP-50 showed radiopacity significantly greater than groups AB/PRP-100 and AB. Conclusion: It can be concluded that the proportion PRP/AB graft influences bone healing in CSD in rat calvaria.

Protocolo radiográfico para a instalação de mini-implantes: descrição da técnica

In the last decade mini-screws have gained popularity in orthodontics field and a correct placement of mini-screws is a critical point to the success of the skeletal anchorage. A careful clinical and radiographic diagnostic before insertion mini-screw is an essential requirement to achieve the central point of the radicular septum. The correct application of these pre-surgical procedures should avoid possible iatrogenic damages in periodontal ligament, dental roots, nasomaxillary cavities, or even important vascular tissues. As of today, periapical radiographs is a regular pre surgical procedure during mini-screw insertion technique. Nevertheless, accurate execution of the radiographic parallax technique can offer to us useful and precise radiographic images, to decide the right local insertion of mini-screws in to the septum bone. The purpose of this paper is to describe the ¬application of new positioning circular guides in conjunction with a ¬parallax radiographic protocol before placement of orthodontic mini-screws.

Diastemas: reestablishment of an attractive smile

A healthy and attractive smile is very valued in today s society. Yet this requires better aesthetic and cosmetic solutions from dental surgeons.The present paper presents a case report of diastema closure using an association of tooth movement induced by orthodontic elastics,dental cosmetics and resin-bonded prosthesis. The female patient L.B.A.J., aged 19 years, visited the Integrated Clinic of Araçatuba DentalSchool UNESP mainly complaining of missing teeth and poor esthetics. After anamnesis, clinical and radiographic examination revealedhypodontia of the maxillary right and left first premolars, abnormal maxillary right lateral incisor shape and diastema between the maxillaryright lateral incisor and canine and between the maxillary left lateral incisor and canine. Planning was done which included indication ofdiastema closure with composite resin restoration and metal-free resin-bonded prosthesis, with a structure made of Vectris (Ivoclar VivadentInc., Amherst, NT, USA). The option for dental cosmetics associated with resin-bonded prosthesis after movement with orthodontic elasticsresulted in an excellent aesthetic outcome of low cost and short treatment duration.Indexing terms: composite resins; diastema; fixed resin bonded partial denture.

Odontoma composto: relato de caso clínico

Os odontomas são os tipos mais comuns de tumores odontogênicos, sendo sua constituição principalmente de esmalte e dentina, com quantidade variável de cemento e polpa. Apresenta relação com dentes inclusos e sua etiopatogenia é desconhecida. Radiograficamente pode ser classificado como composto ou complexo. Acomete com mais frequência pacientes entre a primeira e segunda década de vida, e não há predileção por sexo. Localiza-se principalmente em região anterior de maxila, assintomático e tem associação com dentes inclusos e supranumerários. Neste trabalho relatamos um caso clínico, cuja paciente foi encaminhada para avaliação devido a ausência do dente 33. O diagnóstico clinico-radiográfico inicial foi de odontoma composto. Realizou-se a remoção cirúrgica da lesão e do dente incluso tendo o exame histopatológico confirmado o diagnóstico de odontoma composto.
