ABSTRACT
INTRODUCTION: The aim of this study was to report a patient's clinical case who was diagnosed with severe apical abscess and with autoimmune hepatitis (AIH) using immunosuppressive drugs and bisphosphonate. METHODS: A 32-year-old man of black African descent urgently sought dental surgery because of an increase in volume in the right genic region and a nuisance in the region of the lower right second premolar when chewing. After intraoral and radiographic clinical examination, the patient was diagnosed with pulp necrosis and an acute apical abscess. Because he had AIH and was taking corticosteroids and bisphosphonate (alendronate), he was submitted to endodontic therapy as a minimally invasive treatment, considering his systemic state. RESULTS: After 3 years of follow-up treatment with periapical and tomographic radiographic control, bone repair of the periapical region of the tooth was observed. CONCLUSIONS: Through this report, we can infer that it is possible to reverse the condition of a periapical lesion in a tooth with an acute apical abscess and necrotic pulp in an AIH patient who is using alendronate without the need for more invasive procedures and that would put at risk the patient's general and oral condition in the postoperative period.

BACKGROUND: Teeth with severe crown destruction and endodontically treated may or may not present a circular strip of dental tissue located in the cervical region called ferrule. AIMS: The aims of this study were to evaluate ferrule thickness influence on endodontically treated teeth (ETT) resistance to fracture. MATERIALS AND METHODS: A total of 30 bovine incisor teeth were selected, endodontically treated and randomly distributed, according to the ferrule thickness: G1- no ferrule, G2 - 1 mm, and G3 - 2 mm. All the teeth were restored with prefabricated posts and composite resin. Resistance to fracture was established as the compression strength at 45° tilt at the lingual surface of the crown. STATISTICAL ANALYSIS USED: Data were analyzed using ANOVA and Tukey's test. RESULTS: Resistance to fracture of G1 and G2 were significantly higher than that of G3 (P < 0.001). The pattern of fracture, common to all groups, occurred at the composite resin on the coronary portions. CONCLUSION: Ferrule thickness can influence the resistance to fracture of ETT.
