Profile of chronic and aggressive periodontitis among Senegalese.

Purpose: To describe the profile of chronic and aggressive periodontitis among Senegalese (West Africans) attending the In¬stitute of Dentistry of Dakar. Methods: A retrospective study was conducted with an inclusion period running from 2001 to 2008. The sample included 413 chronic periodontitis and 151 aggressive periodontitis cases, among them 299 males and 265 females selected from 2,274 re¬cords. A Student’s independent t-test or Pearson chi-squared test was used for data analysis. Results: The proportion of females with aggressive periodontitis was significantly higher than those with chronic periodon¬titis (64.9% vs. 40.4%, P<0.001). The aggressive periodontitis patients had an average age of 28.1±8.9 years, and had lost less than 3 teeth. Less than a third of them reported using a toothbrush. Attachment loss was as high as 8 mm and severe lesions had spread to an average of 12 teeth with maximum alveolar bone loss up to 80%. The chronic periodontitis patients had an average age of 44.9±14.0 and had lost on average less than 3 teeth. Nearly 75% used a toothbrush. Attachment loss was signifi¬cantly higher and lesions were more extensive in the aggressive periodontitis. Chronic periodontitis is associated with risk factors such as smoking or diabetes mellitus in 12.8% versus 0.7% in aggressive periodontitis (P<0.001). Differences between the two groups for most clinical and radiographic parameters were statistically significant. Conclusions: The profile of aggressive periodontist is characterized by more severe lesions than chronic periodontitis, where¬as tooth loss experience is similar in both forms. Keywords: Aggressive periodontitis, Chronic periodontitis, Epidemiology, Periodontal diseases, Risk factors.
