Periodontitis is a prevalent destructive gum disease, characterized by loss of tissues supporting the teeth. The two main forms, chronic and aggressive have not been assessed in Kinshasa, DR Congo. Aim: The aim of this study was to investigate the Prevalence and the pattern of chronic periodontitis (CP) and aggressive periodontitis (AP) in order to improve its management. Materials and Methods: A cross sectional study of 404 subjects attending the dental services of the four hospitals of Kinshasa city, from October 2013 to April 2014 was carried out. The plaque index (PlI), bleeding on probing (BOP), probing pocket depth (PPD) and frequency of tooth brushing (FTB) were the parameters assessed. The SPSS software version 20.0 was used. Results: Out of 404 patients examined, 322 (79.7%) had chronic periodontitis versus to 44 (10.9%) of aggressive periodontitis. The female was higher than males with a sex ratio of 1.49:1 and the age group between 20 and 29 was the most represented. PPP of ≥6 mm was found in 24.6%, 5 or 5.5 mm in 27.3% and PPP of 3.5 to 4.5 mm in 48.1% of patients with periodontitis. Significant difference was found between CP and AP according to age variable, p-value < 0.001. PlI for CP was 0.97 (SD ± 0.38) while that for AP was 0.90 (SD ± 0.43). No significant differences were found between PlI, p-value = 0.47; FTB (p = 0.055) and BOP of subjects with AP and those with CP (p = 0.105). Conclusion: The two main forms of periodontitis diseases are more prevalent in patients attending dental services in Kinshasa and affect male as well as female. Age remains an essential variable to distinguish between CP and AP.
