Apical Surgery: Therapeutic Option for Endodontic Failure
Bibliographic record
Abstract
AbstractThe aim of this study is present a surgical solution of the case of endodontic root canal failure caused by overfilling, with a history of endodontic retreatment and aesthetic rehabilitation with porcelain veneers. Patient C.F.P.L, 50 years old, female, was looking for treatment complaining of pain. Previous endodontic treatment was reported on tooth 11, and root canal retreatment after 6 months due to the persistence of painful symptomatology. Later, the patient carried out aesthetic rehabilitation with porcelain veneers, and approximately 6 months later the vitro pain related to the tooth 11 occurred again. Radiographic and tomographic images showed obturation of the root canal of the tooth 11 associated with diffuse hypodense area in the periapical region, with overextended endodontic material. The probable clinical diagnosis was symptomatic traumatic apical periodontitis, and apical surgery was proposed as treatment plan. After infiltrative anesthesia, a Newmann incision and split flap were performed, followed by osteotomy with micro-chisel and curettage of the lesion. An apicectomy was performed with Zecrya drill, followed by retro cavity with diamond ultrasonic tip and retrograde obturation with white MTA. After 2 years of follow-up bone neoformation and absence of symptomatology were observed, tooth in function and preservation of aesthetic rehabilitation harmony. Apical surgery is a therapeutic alternative with favorable prognosis for the treatment of endodontic failure, provided that it is correctly indicated and with a wellexecuted surgical protocol.Keywords: Apicectomy.

ResumoO objetivo deste estudo é apresentar a resolução cirúrgica de um caso de insucesso endodôntico ocasionado pela sobre obturação do canal radicular, com histórico de retratamento endodôntico e reabilitação estética com facetas cerâmicas. Paciente C.F.P.L, 50 anos, gênero feminino, procurou atendimento odontológico queixando-se de dor. Foi relatado tratamento endodôntico prévio no dente 11, e retratamento do canal radicular após 6 meses devido à persistência de sintomatologia dolorosa. Posteriormente, a paciente passou por reabilitação estética com facetas cerâmicas e, aproximadamente 6 meses após, houve o reaparecimento de dor espontânea relacionada ao dente 11. As imagens radiográficas e tomográficas revelaram obturação do canal radicular do dente 11 associado à área hipodensa difusa na região periapical, com extravasamento de material obturador. O diagnóstico clínico provável foi de periodontite apical sintomática traumática, e plano de tratamento proposto uma cirurgia parendodôntica. Posterior a anestesia infiltrativa, realizou-se incisão do tipo Newmann e retalho dividido, seguido de osteotomia com micro cinzel e curetagen da lesão. A apicectomia foi realizada com broca Zecrya, seguida da confecção da retrocavidade com ponta ultrassônica diamantada e obturação retrógrada com MTA branco. Após 2 anos de proservação foi observada neoformação óssea e ausência de sintomatologia, dente em função e preservação da harmonia da reabilitação estética. A cirurgia parendodôntica é uma alternativa terapêutica com prognóstico favorável para o tratamento do insucesso endodôntico, desde que corretamente indicada e com protocolo cirúrgico bem executado.Palavras-chave: Apicectomia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
