Several variables can influence the treatment and outcome of orthognathic surgery, one of which is the angle of the mandibular ramus. The objective of this study is to analyze the upper airways (UA) of patients prior to orthognathic surgery, using cone-beam computed tomography (CBCT) and to correlate their volume with the angle of the mandibular ramus. DICOM (Digital Image Communication in Medicine) images of a radiology clinic were used, with a survey of 124 full face CBCT scans, from 2015 to 2018, and the measurement of the total volume in mm² through software. To obtain the values of the angle of the mandibular ramus, images obtained from medical reports were used, through morphological evaluation. The values were tabulated and subsequently statistical analysis was performed using the ANOVA test to assess the differences between the mean airway volumes (mm²) according to gender, age and mandibular ramus angle. However, the angle of the ramus did not influence the volume of the UA, but a greater average of UA volume was observed in male individuals and in individuals over 34 years of age. There is no evidence that it is possible to measure or predict the volume of the UA by evaluating the angle of the mandibular ramus. [ABSTRACT FROM AUTHOR]

Root Canal Obliteration (RCO) is a condition resulting from physical or chemical trauma to the affected tooth, characterized by the position of mineralized tissue in the pulp chamber and/or root canals. It may eventually progress to pulpal necrosis, requiring endodontic treatment. This is always tricky, due to the difficulty of locating, cleaning and shaping the canals. Clinical and imaging exams are mandatory for proper diagnosis. Thus, the use of cone beam computed tomography (CBCT) is essential for planning. In an auxiliary way, the use of the operative microscope (OM), ultrasonic inserts and rotary instruments made of nickel titanium (NiTi) with heat treatment, increase the chances of success. This case report addresses the endodontic treatment of tooth 17 with obliteration of the root canals, using CBCT, OM, ultrasonic inserts and an automated instrumentation system. It is concluded that the association of these technological resources was efficient and predictive of success in this clinical condition. [ABSTRACT FROM AUTHOR]

Teeth with persistent apical periodontitis represent a challenge in clinical practice, because bone repair cannot be promoted in certain situations with endodontic retreatment alone. Thus, periapical surgical approaches are needed, especially when dealing with true cysts, or in cases of extraradicular biofilm. This case report describes a case of endodontic surgery on teeth 11, 21 and 22, by using leukocyte and platelet-rich fibrin (L-PRF), considering previous endodontic retreatment. The planning included cone beam computed tomography images, surgical treatment with periapical lesion curettage, apicoectomy, retrograde preparation, retrograde filling, and grafting with plugs and L-PRF membranes. A 2-year clinical, radiographic and tomographic follow-up showed bone repair and absence of clinical signs of infection. The use of contemporary techniques, combined with modern imaging resources in diagnosis, planning and follow-up favored the success of the treatment. [ABSTRACT FROM AUTHOR]

Periapical cysts or radicular cysts are inflammatory processes formed in the periapex of a tooth that presents pulp necrosis. They start from the proliferation of epithelial remnants of Malassez through the inflammatory process. This study aims to demonstrate a clinical case of inflammatory periapical cyst associated with a treatment of (GTR), in which the diagnostic hypothesis and the determination of the correct treatment plan will be confirmed through images from the Cone Beam Computed Tomography. After local anesthesia with 2% lidocaine, a horizontal intrasulcular incision and a vertical relaxant beyond the mucogingival junction were performed to fold the flap. Osteotomy for widening access to the cyst region, wound curettage, and decontamination of the root surface. Insertion of the biomaterial and covering with an absorbable collagen membrane. The use of the RTG technique associated with the assessment of CBCT, and the trans and postoperative care proved to be effective for a correct prognosis. [ABSTRACT FROM AUTHOR]

Ponticulus posticus (PP) é uma variação anatômica caracterizada por ser uma ponte óssea entre a parte posterior do processo articular superior e a parte posterolateral do arco posterior da vértebra Atlas (C1). Essa variação pode estar associada à sintomatologia dolorosa. Este estudo visa a contribuir com mais dados a respeito do PP, investigando sua prevalência e utilizando tomografias computadorizadas de feixe cônico (TCFC) realizadas em população brasileira, correlacionando sexo, idade e, principalmente, manifestações clínicas. Foram analisados 673 TCFC de pacientes brasileiros, em que 167 (24,81%) exames analisados apresentaram o PP. A presença e o tipo de PP foram avaliados e categorizados como parciais ou completos, unilateral ou bilateral. A relação da presença do PP com a sintomatologia foi feita por meio de um questionário. No total 39 (23,35%) indivíduos participaram da pesquisa quanto à etapa de coleta de informações a respeito da presença ou da ausência de sintomatologia que pudesse ser relacionada à presença do PP, sendo 23 (58,98%) do sexo feminino e 16 (41,02%) do sexo masculino. Em 11 (28.20%) pacientes, verificou-se estrutura anatômica parcialmente no lado esquerdo, enquanto oito (20,51%) apresentaram a estrutura anatômica parcialmente no lado direito. No que diz respeito à presença bilateral, nove (23,07%) pacientes a apresentaram. Não houve associação de nenhuma sintomatologia com os tipos de classificação dos PP (valor-p > 0,05) e nem relação estatística entre sexo e idade. Assim, foi possível concluir que inexiste correlação comprovada entre a presença do PP e a presença de manifestações clínicas.

Objetivo: investigar a literatura relacionada à aplicação e desempenho da Inteligência Artificial (IA) em exames de imagem odontológicos. Revisão de literatura: foram incluídos 70 trabalhos experimentais e revisões sistemáticas da literatura, publicados em inglês, no período entre 2018 e 2021, que analisaram a aplicabilidade da IA na detecção automática de: pontos cefalométricos, lesões de cárie, lesões apicais, perda óssea periodontal, sistemas de implantes, cistos e tumores odontogênicos, osteoporose, sinusite maxilar, terceiros molares e canal mandibular, ateromas em carótida, fratura radicular vertical, osteoartrite em articulação temporomandibular, avaliação de morfologia radicular e numeração dentária. Resultados: 58,73% dos trabalhos analisados mostrou acurácia diagnóstica acima de 80% com a utilização de IA. Discussão: A maior limitação encontrada foi em relação à aquisição de amostras em quantidade suficiente para treinamento e teste dos modelos, já que imagens radiográficas têm sua disponibilidade limitada por questões éticas e legais relativas aos pacientes e Instituições. A falta de padronização na segmentação e processamento das imagens foi outro fator a influenciar os resultados obtidos, dificultando comparação e generalização. Apesar disso, diversos estudos apresentaram sugestões ou possíveis aperfeiçoamentos para pesquisas futuras, de forma a reduzir estas limitações. Conclusão: A aplicação da IA no diagnóstico por imagens mostrou-se promissora nas diversas áreas pesquisadas, com desempenhos muito semelhantes ou mesmo superiores, muitas vezes, ao desempenho dos profissionais humanos. Contudo, para a legitimação de sua utilização como parte do fluxo de trabalho na clínica, limitações ainda presentes devem ser superadas, especialmente no treinamento dos algoritmos para obtenção de melhores valores de acurácia.

Background: Sleep bruxism (SB) is an oromandibular activity with teeth grinding and clenching and a masticatory muscle activity. It generates temporomandibular dysfunction (TMD), tooth wear and mobility, as well as other clinical findings. It is important to analyze occlusion and TMJ to determine how it is affected by the biomechanical load generated by bruxism. Purpose: To establish the relationship between the condylar position of the temporomandibular joint (TMJ) using cone beam computed tomography (CBCT) with the dental wear patterns determined with the BruxChecker®, in subjects with a clinical diagnosis of sleep bruxism. Methods: Observational, descriptive, cross-sectional study in 45 patients with clinical diagnosis of sleep bruxism, according to the bruxism diagnostic criteria of the AASM (American Academy of Sleep Medicine), with an average age of 34.9 ± 8.6. The CBCT were analyzed, measuring the spaces of the TMJ in the sagittal plane: anterior, superior and posterior (SA, SS, SP) and in the coronal plane: lateral, superior and medial (Cl, CS, CM). The pattern of dental wear was classified with the BruxChecker® by dividing the subjects into: Group 1, canine pattern (CP) with 19 subjects and Group 2, molar pattern (MP) with 26 subjects. Results: No significant differences were observed between the measurements of the joint spaces of each group nor in the comparison between the PC vs PM patterns. The sagittal position of the condyle posterior/anterior(P/A) was posterior and the coronal medial/lateral (M/L) was medial for the two groups, when evaluating the ratios. Significant difference (P <0.00) was found in right pattern CP and MP, when estimating the difference between averages of medial and lateral spaces. Conclusions: The position of the condyle was found posterior and medial in the articular fossa, in the right CP and in the left MP. A significant right lateral condyle position was evidenced in PC and PM. These findings indicate an altered condylar position in subjects with bruxism, which can be associated with joint distraction, possibly generated by constant eccentric mandibular movements during bruxism.

Background: A wide range of functional devices allow stimulating mandibular growth in class II patients, through mandibular advancement; managing to correct this type of skeletal and occlusal disharmony. Fixed repositioning appliances apply constant forces to the TMJ and may cause remodeling of the articular condyle and glenoid fossa. Computed tomography (CT) has been the gold standard for imaging the bone and hard tissues of the TMJ, but today cone beam computed tomography (HCCT) and Nuclear Magnetic Resonance (MRI) are used, because of their low and zero levels, respectively, of radiation. Objective: to measure morphological changes through TMJ imaging evaluation after correction of class II malocclusion with functional treatment with appliances in growing patients Methods: a comprehensive systematic literature search was conducted from January 2015 to May 2023 in the following bibliographic databases PubMed, EBSCO, Embase, and the Cochrane Library. Results: 10 studies were selected. The total sample size was 210 patients, and the age range was 10.3 to 14 years. The main imaging method used was HCCT with n = 9. Conclusions: The main change described is condylar remodeling, followed by morphological adaptation of the fossa. Although no significant differences have been reported in morphological changes in the TMJ between fixed versus removable functional appliances, fixed appliances cause a higher incidence of morphological changes.

Aim: To evaluate, tomographically, in two clinical cases, the effect of the new MTA formulation of the Angelus, the MTA Repair HP, in the contribution to remission of periapical lesions in paraendodontic surgery, as well its physical properties and manipulation. Case report: Patient R.C.R, 57, attended at the Faculty of Dentistry of the Federal University of Juiz de Fora for evaluation of periapical lesion in the element 11. It was observed, at the clinical and radiographic exams, endodontic treatment and a circumscribed, unilocular and radiolucid area at the apex of the tooth. It was requested a CBCT exam (I-Cat®, Imaging Sciences International, Hatfield, Pennsylvania, USA), which confirmed the presence of the lesion and rupture of the buccal cortical plate. Thus, it was performed curettage, apicectomy, retropreparation and retrofilling with the described cement. It was solicited two additional CBCT exams at the period of three and five months post-operative. Patient R.J.G.M, 46, with mean complain of pain, increased intraoral volume and purulent discharged in the upper left arch. The clinical and radiographic exams revealed fistula and refractory lesion, despite the endodontic treatment of the tooth 25. A CBCT exam was done and it was observed a circumscribed hypodense area, around the apex of the 25, with rupture of the buccal cortical plate. It was suggested the same surgical treatment described in the case above. It was performed two more CBCT exam, at three and five months after the procedure. Discussion: The MTA Repair HP was developed from the necessity of a more biocompatible material with the dental structures in the retrograde filling process. This product helps in the remission of periapicals lesions and in the new formation of the periodontum components; also it has the advantages of longer setting time, not causing the darkening of the coronary portion and easier manipulation. Conclusion: Regarding the remission of the lesions, it was noticed the generation of calcified tissue across the periods of three and five months. Regarding the manipulation and application, it was not observed any improvement related to the addition of the plasticizer. However, it was noticed a shorter setting time, making it difficult to insert the material.

Aim: To investigate the prevalence and location of bifid mandibular canals (CMB) using cone beam computed tomography (CBCT). Materials and methods: Three trained and calibrated dental radiologists individually evaluated 1254 CT scans using the I-Cat Vision software (Imaging Sciences International®) and classified them into four distinct types (Retromolar, Dental, Forward and Bucolingual). Frequency data, collected from an Access form (Microsoft® Office), were analyzed using the Fischer and Friedman test. The level of statistical significance was set at 5%. Results: CMBs were found in 276 cases (22%), with no gender predilection (P = 0.186). There was a statistically significant difference between the types (P = 0.001). Discussion: The recognition of a CMB is of great relevance when associated with anesthetic and surgical procedures in the posterior region of the mandible. Although many studies have shown that CMB is not commonly seen, a failure to identify it can result in damage to the lower alveolar nerve (NAI) or difficulty in obtaining anesthetic block. Conclusion: The most frequent type of CMB in both genders was retromolar (P = 0.001), representing 18.5%, and visualized with rates of 47.1% in women and 52.9% in men. The frequency of CMBs analyzed using the CBCT was significant in the population evaluated and presented in different configurations. Thus, its investigation should not be neglected in the face of surgical procedures that involve the posterior region of the mandible.

Introdução: A reabsorção inflamatória interna é uma condição rara, caracterizada por uma inflamação crônica da polpa, apresentando a formação de tecido de granulação com exposição de dentina mineralizada. Quando uma perfuração é detectada, o tratamento conservador ou cirúrgico pode ser indicado. Objetivo: O presente relato de caso descreve uma reabsorção interna perfurante de rápida evolução em molar inferior, que foi tratada com Agregado de Trióxido Mineral (MTA) como material obturador. Relato de caso: Paciente do sexo feminino, 23 anos de idade, apresentou dor à mastigação no dente #36. Foi estabelecido o diagnóstico de periodontite apical aguda causada por contato prematuro, e o tratamento foi ajuste oclusal associado à prescrição de anti-inflamatório. Seis meses depois, nenhum sintoma foi relatado. Porém, a radiografia periapical mostrou uma reabsorção interna de grande dimensão na raiz mesial, associada à lesão de furca. Ao exame tomográfico, foi possível observar a presença de reabsorção interna do tipo perfurante. O tratamento endodôntico foi realizado e o canal foi obturado com MTA. Resultados: No acompanhamento de dois anos, as imagens tomográficas do dente mostraram cicatrização total do tecido ósseo e o dente estava clinicamente em função e sem sintomas. Conclusões: O tratamento de uma reabsorção interna perfurante pode ser conduzido com sucesso sem intervenção cirúrgica, quando um material bioativo apropriado é utilizado para preencher o canal. No entanto, um efetivo preparo biomecânico do sistema de canais radiculares deve ser realizado para se alcançar esse resultado. [ABSTRACT FROM AUTHOR]

A tomografia computadorizada de feixe cônico (TCFC) é um aprimoramento da tomografia convencional, desenvolvida especialmente para a avaliação da região maxilofacial. A TCFC produz imagens tridimensionais que permitem sua utilização em diversas áreas da odontologia. O objetivo desta revisão de literatura é mostrar, com base na literatura, a diversidade de aplicações no âmbito odontológico que tal exame imagenológico apresenta, ressaltando os seus benefícios e limitações nas distintas especialidades odontológicas. O presente estudo consiste em uma pesquisa de caráter exploratório, realizada por meio de uma revisão da literatura narrativa. O levantamento bibliográfico foi realizado por meio de fichamentos de artigos de periódicos nacionais e internacionais, teses, dissertações e outras publicações, encontradas nas bases de dados da biblioteca digital (Google Acadêmico, BVS, Sciencedirect, Researchgate, Scielo, Wiley Online Library, Pubmed), nos anos de 2000 a 2020. Os artigos que antecedem essa data foram selecionados por apresentarem caráter histórico sobre o tema proposto. Conclui-se que o cirurgião-dentista deve estar ciente dos avanços tecnológicos que ocorrem na área de imagenologia odontológica para gerir com mais eficiência os diagnósticos e tratamentos, evitando, assim, possíveis erros. A TCFC demonstra possuir múltiplas indicações nas diversas especialidades odontológicas, cada caso deve ser avaliado individualmente, analisando a real necessidade do seu uso. Nos casos em que há a necessidade de sua utilização, o seu custo-benefício é melhor que qualquer desvantagem que ela possa apresentar.

Three-dimensionally evaluation of the treatment changes of a Herbst appliance using a lower anchorage unit not touching the lingual surface of the lower incisors. The sample consisted of 23 Class II:1 patients (12 males, 11 females) with a mean age of 15.7±1.7 years treated with a Flip-Lock Herbst® appliance (TP Orthodontics, Inc., La Porte, IN, USA). The lower anchorage unit for the Herbst appliance consisted of two anchor bands connected by a lingual arch with 3mm distance from the incisor's lingual surface. Treatment changes in mandibular incisor inclination, overjet and overbite were evaluated by means of cone beam computed tomography images (i-CAT® Classic unit, Imaging Sciences International, Hatfield, PA, USA) obtained before and after treatment with the Herbst appliance. On average, there was a statistically significant increase in mandibular incisor inclination (2.6+1.8°) and a reduction in overjet (3.2+2.2mm) and overbite (1.3+0.9mm). Genders did not differ significantly. Incisor proclination was however only seen in 74% of the patients. The changes in mandibular incisor inclination were associated with the changes in overjet (/r/= 0.1 to 0.5) and overbite (/r/= 0.3 to 0.7). A Herbst appliance with a mandibular anchorage unit distant from the incisor's lingual surface results in smaller amounts of mandibular incisor proclination compared to literature. However, as it induces canine anchorage loss, the decreased amount of proclination may not prevail after multibracket treatment. [ABSTRACT FROM AUTHOR]

Introdução: A probabilidade de melhoria do espaço aéreo superior (EAS) com cirurgia ortognática deve ser considerada durante a decisão do tratamento ortodôntico-cirúrgico, proporcionando não somente um benefício estético, mas também funcional, para o paciente. Objetivo: O objetivo do presente estudo foi avaliar as alterações 3D no espaço das vias aéreas superiores após a cirurgia de avanço maxilomandibular (AMM). Métodos: Foi realizada uma análise retrospectiva de 56 pacientes, 21 homens e 35 mulheres, com média de idade de 35,8 ± 10,7 anos, submetidos a AMM. Foram obtidas tomografias computadorizadas de feixe cônico (TCFC) pré- e pós-operatórias para cada paciente, e as alterações no EAS foram comparadas usando o software Dolphin Imaging v. 11.7. Foram medidos dois parâmetros do espaço aéreo faríngeo (EAF): volume das vias aéreas (VVA) e área axial mínima (AAM). Foi utilizado o teste t pareado para comparar os dados entre T0 e T1, com nível de significância de 5%. Resultados: Houve um aumento estatisticamente significativo no EAS. A cirurgia de avanço bimaxilar aumentou o volume das vias aéreas (VVA) e a área axial mínima (AAM) em média 73,6 ± 74,75% e 113,5 ± 123,87%, respectivamente. Conclusão: A cirurgia de AMM tende a causar o aumento significativo do EAS; no entanto, esse aumento é altamente variável. [ABSTRACT FROM AUTHOR]
