Determination of frequency distribution of aggressive periodontitis in dental clinic of Rasht dental school in 2016-2017

Introduction: Aggressive periodontitis is a type of periodontal disease that affects systemically healthy individuals usually under the age of 30 years. It is characterized by rapid bone destruction, which is not proportionate to the quantity of bacterial plaque. The purpose of the present study was to determine the frequency of aggressive periodontitis in periodontics clinic of Rasht dental school in one year period. Materials and Methods: In this cross-sectional study, 412 patients were selected among those presenting to the Periodontics clinic of Rasht Dental School during 2016-2017 by convenience sampling. The probing pocket depth (PPD) at 6 areas around the incisors and first molars was recorded for each patient. Those with PPD ≥ 4 mm in more than one tooth were referred for radiographic examination. After extraction of relevant clinical trial parameters, data were analyzed by a descriptive statistical method using IVM SPSS Statistical Software (Version 25). Results: Of examined patients, only 2 fulfilled the diagnostic criteria for localized aggressive periodontitis. No one was diagnosed with generalized aggressive periodontitis. The frequency of aggressive periodontitis among the patients was %0.48. Conclusion: The current results were different from those of previous studies on the same age groups with similar diagnostic criteria conducted in other countries. This difference can be attributed to the difference in sample size and different epidemiological patterns of the disease in our target city, Rasht.
