Comparison of the clinical effectiveness of a single and a triple-headed toothbrushes in a population of mentally retarded patients.

Tooth brushing is a very simple and effective method for removing daily dental deposits and for preventing dental and periodontal diseases. However, it can cause considerable manipulative difficulties among some populations, e.g.

[Bacteriological aspects of periodontal disease].

Periodontal diseases are caused by specific bacteria in the periodontal pocket. Despite the vast complexity of the flora on the teeth and the more than 300 types of bacteria that may be found in the mouth, studies have been able to narrow the list of pathogens to a small group of suspected bacteria. It is not clear, however, how much of the destruction of periodontal tissue is caused by the direct effects of the bacteria and how much by indirect effects mediated by the host's reaction to the bacteria.

[Microbiological tests in the diagnosis of periodontal disease].

Today our knowledges concerning microbial aetiology and periodontal pathogeny allow us to use some tests in our private practice, that are different from those of yesterday. This article will attempt to review them.

The effect of clindamycin gel insert in periodontal pockets, as observed on smears and cultures.

This study is aimed at the evaluation of a 1% clindamycin hydrochloride containing gel on the microbial flora of periodontal pockets deeper than 5 mm. In order to achieve that purpose, 20 patients with pocketing in the premolar-molar regions were selected. Active and placebo gel were inserted once during the first 2 weeks of this experimental study.
