This study evaluated the preferences of general dentists regarding vital and nonvital tooth bleaching therapies and investigated whether the time of clinical practice and post-graduate training influence these options. A cross-sectional study was conducted using a questionnaire with closed questions applied to dentists (n=276) of a mid-sized city of the southern Brazil (Pelotas, RS). Informatio...

PURPOSE The aim of this study was to compare all ceramic inlay/onlay survival rates in vital and nonvital teeth having the same cavity design. Filling the pulp chamber with ceramic materials or not was also discussed. MATERIALS AND METHODS Ceramic class II inlays/onlays were made on 11 premolars and 30 molars: 14 vital, 27 endodontically treated. The same tooth preparation design was performe...

Attachment of certain bacteria to living arbuscular mycorrhizal fungal extraradical hyphae may be an important prerequisite for interactions between these microorganisms, with implications for nutrient supply and plant health. The attachment of five different strains of gfp-tagged soil bacteria (Paenibacillus brasilensis PB177 (pnf8), Bacillus cereus VA1 (pnf8), Pseudomonas fluorescens SBW25<gf...

This report presents the case of a 10-year-old patient with a nonvital young permanent tooth which was managed by pulp revascularization. Following disinfection of the canal by irrigation with NaOCl and use of a triantibiotic paste, a scaffold was created by inducing the formation of a blood clot within the canal. At the subsequent follow-up visits, the patient was asymptomatic, with normal res...

Traumatized teeth can bleed internally, causing discoloration over time. When this occurs in the smile zone, masking the dark colorations can present challenges when attempting to practice conservative cosmetic dentistry. Implementing nonvital bleaching can significantly improve the dark colorations of the traumatized teeth and support very conservative cosmetic dentistry. Effective communicati...

The aim of this study was to compare the morbidity of permanent teeth associated with mandibular fractures treated with plates with those treated with interdental wiring. Fractures involving third molars were excluded. Sixty-three teeth in the line of fractures in 40 patients were investigated clinically (tooth vitality; periodontal status) and with periapical radiographs. Of these, 34 teeth we...

The aim of this study is to report a case of a nonvital, discolored, maxillary central incisor bleached by 35% hydrogen peroxide gel with the use of glass ionomer cement as a mechanical barrier in an attempt to minimize the undesirable side effects of intracoronal bleaching. The patient was a 13-year-old boy complaining of a discolored nonvital upper-right central incisor and was selected for t...

To perform advanced periodontal therapy to save a natural tooth or to extract it and place an implant-which is best? Several considerations need to be made to make the proper decision. Endodontic conditions, proper reconstruction of a devitalized tooth, and the possibility of correct prosthetic treatment are all factors to be considered. From a strictly periodontal point of view, in the presenc...

This study compares the incidence, degree, and length of postoperative pain in 300 endodontically treated teeth, with and without apical patency, in relation to some diagnostic factors (vitality, presence of preoperative pain, group, and mandible of treated tooth). Of the questionnaires received back, apical patency was maintained during shaping procedures with a #10 K-file in one group (n = 11...

Relatively few long-term studies have been performed to evaluate the clinical success of one-appointment pulpectomies in primary molar teeth. The purpose of this retrospective study was to evaluate the radiographic appearance of nonvital primary molars before and after treatment with a one-appointment formocresol pulpectomy technique. The mean length of time since pulpectomy treatment for the 6...
