BACKGROUND To evaluate the incidence of flare-ups and identify the risk factors including age, gender, tooth type, number of root canals, initial diagnosis, the type of irrigation regimen, treatment modality and the number of visits, in patients who received root canal treatment from January 2002 to January 2008. METHODS Records of 1819 teeth belonging to 1410 patients treated by 1 endodontic...

The diagnostic value of dark-gray discoloration of the crown of primary incisors following traumatic injury as a predictor of pulp vitality is controversial. This retrospective study attempted to examine the condition of the pulp of primary incisors with dark-gray discoloration following traumatic injuries. Forty-eight gray caries-free, traumatized primary incisors were examined clinically and ...

Objective: The objective of this report was to present a case of apexification in traumatized teeth treated with two different therapies for immature teeth. Methods: An 11-year-old male patient was referred to the Dental Trauma Service of the College of Dentistry — Piracicaba (UNICAMP), with enamel dentin fracture in the maxillary central incisors associated with subluxation caused by a bicycle...

The purpose of the investigation was to assess the depth of inf lammatory reactions in the exposed pulps of crown-fractured and ground teeth. Thirty-six incisors in 11 adult monkeys were used for the experiments. In 24 teeth, the pu lp was exposed by grinding or by crown fracture, and the pulpal reactions were examined after 3, 48, and 168 hours. In three-hour specimens, the depth of early chan...

INTRODUCTION Intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. Residual sealer left in pulp chamber after obturation can cause discoloration. The objective of this in vitro study was to evaluate coronal discoloration created by AH26 a...

dens invaginatus is a rare developmental anomaly of teeth with complex root canal system morphology. the present case describes a peg shape maxillary lateral incisor with dens invaginatus (oehlers type ii), necrotic pulp, and an associated large periradicular lesion. nonsurgical endodontic treatment was performed with the aim of removing the blind sac with diamond bur under the use of operating...
