The incidence of unfilled second mesiobuccal canals and periapical lesions in maxillary molars by cone-beam computed tomography E-VOL DX software

This study evaluated the incidence of unfilled second mesiobuccal (MB2) canals and periapical lesions in first maxillary molars using CBCT e-Vol DX software. Hence, 326 CBCT images of first maxillary molars of patients undergoing endodontic treatment were selected. The e-Vol DX software performed a retrospective review of these images, recording the presence or absence of MB2 canals, filling, and periapical lesions in first maxillary molars. Specific statistical analysis was performed at a 5% significance level. Unfilled MB2 canals were highly frequent in first maxillary molars and significantly associated with periapical lesions in the mesiobuccal root of these teeth (p<0.05). The CBCT e-Vol DX software effectively detected MB2 canals, and unfilled canals may be associated with periapical lesions.

Generalized Periodontal Disease Treated with Conservative Periodontal Therapy ­ Case Report and Literature Review / Doença Periodontal Generalizada Tratada com Terapia Periodontal Conservadora ­ Relato de Caso e Revisão da Literatura

Periodontal disease is an infectious-inflammatory disease caused by the presence of bacteria in the dental biofilm, leading in many cases to tooth loss. The objective of this work is to report a clinical case of generalized periodontal disease. Female patient, sought the Dental Clinic of the University of Passo Fundo, complaining that her upper dental arch was increasingly "crooked" and felt a little "mobility". , being diagnosed with stage II periodontitis, due to the pandemic, the patient was only able to return to the Dental Clinic after 5 months, when new exams were carried out, with an increase in the probing depth reaching 7mm in some sites, having a new diagnosis periodontal disease, periodontitis stage III of the disease. The patient's treatment plan consisted of adapting the oral environment, through oral hygiene guidance, prophylaxis, supragingival and subgingival scaling. After 6 months of follow-up, it can be noted that the proposed treatment it was not satisfactory, because, after doing a new periogram, there was no regression of the disease. as for oral hygiene, the patient did not cooperate with the treatment and the installation of orthodontic appliances was not recommended. Periodontal maintenance along with the patient's cooperation is essential to achieve successful periodontal treatment, but in the following case report there was no success in periodontal therapy, and the patient's lack of cooperation could be one of the reasons.

A doença periodontal é uma doença infecto-inflamatória, causada pela presença de bactérias do biofilme dentário, levando em muitos casos a perda dentária. O objetivo do trabalho é relatar um caso clínico de doença periodontal generalizada. Paciente do sexo feminino, procurou a Clínica Odontológica da Universidade de Passo Fundo, reclamando que sua arcada dentária superior estava cada vez mais "torta" e sentia uma pequena "mobilidade". No exame clínico, a sondagem periodontal foi superior de 3mm chegando até 5mm, sendo diagnosticada com periodontite estágio II, por motivos da pandemia a paciente só conseguiu retornar a Clínica Odontológica depois de 5 meses, quando novos exames foram realizados, sendo verificado um aumento da profundidade de sondagem chegando até 7mm em alguns sítios, tendo um novo diagnostico periodontal, periodontite estágio III da doença. O plano de tratamento da paciente consistia em adequação do meio bucal, por meio de orientação de higiene oral, profilaxia, raspagem supragengival e subgengival. Após 6 meses de acompanhamento, pode-se destacar que o tratamento proposto não foi satisfatório, pois, após fazer um novo periograma, não houve regressão da doença. Com intuito de motivar a paciente com hábitos de higiene bucal, a paciente não colaborou com o tratamento e não sendo indicado a realização a instalação de aparelho ortodôntico. A manutenção periodontal junto com a cooperação do paciente é essencial para alcançar o êxito do tratamento periodontal, mas no seguinte relato de caso não houve sucesso da terapia periodontal, podendo ser um dos motivos a falta de colaboração da paciente.
