Evaluation of the Frequency and Clinical Features of Aggressive Periodontitis

The objective of our study was to determine the frequency of aggressive periodontitis in our patients and to evaluate the correlation between local etiological factors (bacterial plaque) and the severity of the disease through the study of the clinical aspects of this periodontal involvement in our population. A total of 300 patients aged 12 to 35 years, who consulted at our periodontology department, were examined between September 2016 and December 2017. A descriptive study based on a clinical examination using PI and GI indices, periodontal pocket probing, and radiographic examination was conducted. The periodontal disease classification used was that of Armitage (1999). The results showed that aggressive periodontitis was diagnosed in 51 patients, representing a frequency of 17%, and was significantly more frequent in women (82.35%). The association between the PI and GI indices was 60%, representing a positive linear correlation (95% CI: [0.39–0.75]). Periodontal pockets ≥ 4 mm, ≥ 6 mm, and ≥ 8 mm were significantly more common on proximal surfaces than on buccal, palatal, or lingual surfaces. The frequency of aggressive periodontitis in our patients is relatively high, which is significantly related to poor oral hygiene and moderate inflammation.
