[Comparative analysis of conventional dental floss and alternative materials].

The interproximal plaque-removing effect of three different materials (classic dental floss, rafia floss and indian floss) was tested in a group of 80 males (18 years-old). After two weeks all the materials had the same efficacy in removing the bacterial plaque, with significant reduction in interproximal plaque index. According to an opinion inquiry the rafia floss was the most comfortable material to use and has the lowest cost as well.

Occurrence of primary incisor traumatism in Brazilian children: a house-by-house survey.

This paper presents the results of a house-by-house survey to learn the occurrence of dental injury to the primary teeth in Brazilian children from ten to seventy-two months of age. The study sample comprised 576 children, 295 boys and 281 girls living on sixty-six streets selected in an urban area (Bauru) in the state of Sao Paul, Brazil. There were 174 children (30.2 percent) with positive reports of injuries to the primary teeth. The results show the need of an educational program in order to prevent the occurrence of dental trauma.

[Photoelasticity in dentistry. 2. Influence of the supporting apical base].

Thirty photoelastic dental-periodontal patterns were prepared according to the following criteria: ten with cilindrical shaped roots (series I), ten with conical shaped roots from apical do cervical (series II), ten with conical shaped roots from cervical to apical (series III), all of them having the same superficial area and apical basis. The photoelastic analysis showed that the main factor in determining the force distribution is the apical basis and that the conical roots from cervical to apical (series III) elicit a lateral compression on the periodontal support, which influences the magnitude of the force that is necessary to the formation of the some photoelastic deformations produced in the other series. The spectral distribution of the internal stress in the patterns of the series III showed the formations of incomplete fringes along with the lateral aspects of the roots. It was concluded that to make a comparison of the periodontal distribution of occlusal forces, it is of paramount importance the standardization of all steps concerning the construction of the patterns, the measurement of the photoelastic blocks and mainly the apical area of the root, which is the main determinant factor of the qualitative and quantitative results produced by the photoelastic analysis.
