[Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis in aggressive periodontitis in Morocco -- preliminary study].

Abstract

Objective: The microbial eatiology of aggressive perodontitis is different worldwidly. The purpose of this study was to determine the presence or absence of two anaerobic, highly pathogenic bacteria, Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis (P.g) in aggressive periodontitis in a Moroccan population.

Material and methods: Our study involved a sample of 32 subjects, 20 with aggressive periodontitis and 12 with a healthy periodontium. A pool of bacterial samples was performed in each patient looking for Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis by the method of bacterial culture.

Results and conclusion: Microbiological analysis showed an association of the presence of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis with aggressive periodontitis in Morocco. Porphyromonas gingivalis would be less present than Aggregatibacter actinomycetemcomitans in aggressive periodontitis in Morocco (30% vs 83%)(p < or = 0.05%). However, given the small sample size other studies are necessary.
