Association between occlusal anomalies and dental caries in 3- to 5 year-old Brazilian children.

Objective: To investigate the association between certain occlusal anomalies and the occurrence and severity of dental caries in Brazilian preschool children.

Design: Cross-sectional study.

Setting: Twenty-eight public nursery schools in Canoas, southern Brazil.

Bibliometric study of articles published in a Brazilian journal of pediatric dentistry.

This cross-sectional study aimed at evaluating the abstracts of all articles published in the 'Jornal Brasileiro de Odontopediatria e Odontologia do Bebê' in order to collect data on the study design used, the most researched topics and the Brazilian states with the highest scientific production. Copies were made of the abstracts of each article, totaling 572 abstracts. Data categorization was done by two trained and independent reviewers.

Evaluation of the methodologies used in clinical trials and effectiveness of chemo-mechanical caries removal with Carisolv.

This investigation aims to discuss the methodologies applied in clinical trials published about Carisolv, in order to assess the best scientific evidence concerning chemo-mechanical caries removal. Papers concerning the use of Carisolv were sought using a search strategy. The titles and abstracts of all the reports identified through the search were analyzed by a single reviewer.

Histomorphological response of dogs' dental pulp capped with white mineral trioxide aggregate.

This study was conducted to observe the response of dogs' dental pulp to white mineral trioxide aggregate (MTA) when used as pulp capping material. The pulp of 15 dogs' teeth was experimentally exposed and capped with white MTA. The animals were sacrificed two months later and the specimens were prepared for histomorphological study.

A SEM investigation of accessory foramina in the furcation areas of primary molars.

The purpose of this study was to determine the prevalence and anatomic characteristics of accessory foramina in the external and internal furcation areas of primary molars. Sixty human primary molars were divided into two equal groups. The teeth of the experimental group showed in previous radiographic examination the presence of a radiolucency area confined to the inter-radicular region, while the teeth of the control group had no sign of pulpal inflammation in the clinical and/or radiographic examination.

Reaction of rat connective tissue to implanted dentin tubes filled with a white mineral trioxide aggregate.

The purpose of this paper was to study the reaction of rat subcutaneous connective tissue to the implantation of dentin tubes filled with white mineral trioxide aggregate (MTA), a material that will be marketed. The tubes were implanted into rat subcutaneous tissue and the animals were sacrificed after 7 and 30 days. The undecalcified pieces were prepared for histological analysis with polarized light and von Kossa technique for mineralized tissues.
