Enamel of Premolars whose Predecessors Presented Rupture of the Follicle Bone Crypt from Periapical Infections.

Objective: To observe if dental alterations in premolars are associated with the rupture of the follicle bone crypt caused by a periapical lesion in the predecessor molars.

Study Design: This is a cross-sectional study. Data collection consisted of the analysis of medical records, a socioeconomic questionnaire, and dental clinical examination.

Prevalence of Enamel Defects in Premolars Whose Predecessors Were Treated with Extractions or Antibiotic Paste.

Purpose: To determine the prevalence of developmental defects of the enamel (DDE) in premolars whose infected predecessors were submitted to pulp therapy with antibiotic paste or extractions due to pulp necrosis.

Materials And Methods: A cross-sectional study with a consecutive sample consisting of children and adolescents who presented with fully erupted premolars, was evaluated. Data were collected by dental examinations, in which the modified DDE index was applied.

Cellular profile of primary molars with pulp necrosis after treatment with antibiotic paste.

The interradicular region of primary molars is permeated by many foramina, channels and accessories that connect the pulp cavity with the periapical tissues anatomically. Thus, pulp decomposition products or drugs used in endodontic treatment can trigger inflammatory reactions. The aim of this study was to evaluate the blood cell profile of the alveolar region after extraction of primary molars treated with CTZ paste.
