Model for Predicting Temporomandibular Dysfunction: Use of Classification Tree Analysis.

The aim of this study was to construct a predictive model that uses classification tree statistical analysis to predict the occurrence of temporomandibular disorder, by dividing the sample into groups of high and low risk for the development of the disease. The use of predictive statistical approaches that facilitate the process of recognizing and/or predicting the occurrence of temporomandibular disorder is of interest to the scientific community, for the purpose of providing patients with more adequate solutions in each case. This was a cross-sectional analytical population-based study that involved a sample of 776 individuals who had sought medical or dental attendance at the Family Health Units in Recife, PE, Brazil.

Dentifrice Containing Extract of Rosmarinus officinalis Linn.: An Antimicrobial Evaluation.

This study aimed to evaluate the antimicrobial activity of a dentifrice containing an alcoholic extract of rosemary on oral bacteria, compared to a commercially available herbal dentifrice. Standard strains of Streptococcus mutans (ATCC 25175), Streptococcus oralis (ATCC 9811) and Lactobacillus rhamnosus (ATCC 7469) were used, as well as different toothpastes based on rosemary (TR), on propolis (TH), triclosan (positive control) (TPC) and non-fluoridated dentifrice (negative control) (TNC). Bacteria were seeded in Petri dishes and paper discs soaked with dilutions of dentifrice placed on the plates.

Job satisfaction among dental assistants in Brazil.

The aim of the present study was to investigate the expressed levels of job satisfaction of dental assistants working in Brazil and whether there are relationships among professional formation standards, workplace relations and job satisfaction.

[Impact of the existing tooth number on daily performance: pilot study].

To establish the relation between the aspects associated to the number of the teeth and the impact on daily performance it was realized a pilot study with 75 voluntary patients that had been divided in three groups: short arch, complete and toothless. To evaluate the impact the IODD was used (Index of the Oral Impacts on Daily Performance). The results had evidenced that 16% of the participants had at least one daily activity affected.
