RESUMO

OBJECTIVES: To evaluate the prevalence of missed canals in endodontically treated maxillary molars through cone-beam computed tomography (CBCT) images and to verify their association with the presence of periapical lesions. MATERIAL AND METHODS: Three oral radiologists evaluated 633 maxillary molars in CBCT exams regarding number of roots, number of root canals, number of missed canals, anatomic identification of missed canals, presence of periapical lesions, and root location of the periapical lesions. Data were statistically analyzed at a 5% significance level. RESULTS: Descriptive statistical analysis showed that among 395 first molars, 218 had at least one missed canal, and 186 (46.5%) had a missed canal and periapical lesion simultaneously. Of these, 72.4% (134) of the missed canals were only mesiobuccal 2 (MB2). Among 238 s molars evaluated, 121 presented at least one missed canal, and 104 (43.6%) had a missed canal and periapical lesion simultaneously. Of these, 81.7% (85) of the missed canals were only MB2. The chi-squared test showed an association between the presence of missed canals and periapical lesions for 1st and 2nd maxillary molars. Teeth that presented a missed canal showed an odds ratio (OR) of 2.57 (p < 0.0001) of being associated with a periapical lesion. Missed canal occurrence was positively related to the number of root canals (z = 13.06, p < 0.0001), meaning when the number of root canals is higher, there is a higher probability of missed canal occurrence. According to the model calculated prediction, for a one-unit increase in the number of canals, the probability of missed canals increases by 4.22%. CONCLUSIONS: It was concluded that MB2 was the most frequently missed canal, associated with the presence of periapical lesions in endodontically treated maxillary molars. CLINICAL RELEVANCE: Professionals' negligence of anatomical root variations has been contributed to the high prevalence of missed canals, leading to failures in endodontic treatment. Their association with periapical lesion occurrence emphasizes the importance of correct detection and instrumentation of these canals.

RESUMO

O presente estudo, um relato de experiência moldado à técnica qualitativa-descritiva e estruturado sob estratégia narrativa, traz em seu objetivo a descrição de um relato de experiência vivenciado pelo Projeto de Extensão Sala de Espera (UFJF/GV) na UAPS Esperança do município de Governador Valadares, MG. Norteada pela demanda do serviço local, coube à equipe extensionista o desenvolvimento de uma atividade, de cunho educativo-preventivo, abarcando o tema O controle do Aedes aegypti. A dinâmica das ações foi sistematizada em três tempos sequenciados: "O pensar", "O fazer" e "O refletir". Da experiência foram levantados pontos positivos (ambientalização; quantidade de usuários; receptividade e/ou participação da equipe profissional da UAPS; presença do corpo docente como observadores; interpessoalidade e valorização do conhecimento da população) e negativos (dificuldade em lidar com os ruídos do ambiente; falta da construção de um instrumento de avaliação; necessidade de se criar uma identificação do grupo). Em conclusão, além de reconhecer nesse espaço a sensibilização dos usuários em espera frente ao assunto abordado, enfoca-se o papel da extensão universitária em prol de uma formação acadêmica mais contextualizada e humanizada. Afinal, extensão é isso, inserir vida no ensino superior, é dinamizar espaços em prol da almejada coletividade.


This study of an experience report molded by qualitative descriptive technique and structured in narrative strategy brings in its goal the description of an experience report in a Waiting Room Extension Project (UFJF/GV) on UAPS-Esperança municipality Governador Valadares, MG. Guided by local service demand, the team extension performs the development of an activity of educational and preventive nature, covering the topic "control of Aedes Aegypti". The dynamics of the actions was systematized in three sequenced times: "Thinking", "What to do" and "The Reflection". There were positive points raised from the experience (environmentalization; number of users; receptivity and/or participation of the professional team of UAPS; presence of the faculty as observers; interpersonal and enhancement of people's knowledge) and negative points raised (difficulty in giving you the ambient noise; lack of building an assessment tool; need to create a group identification). In conclusion, besides recognizing this space, the awareness of users' waiting in the subject matter, the role of the university extension focuses on the support of a more contextualized and humanized academic training. After all, this extension is to insert life in higher education as a more dynamic space for the community.
