17. OCCURRENCE OF AGGRESSIVE PERIODONTITIS IN SECONDARY SCHOOL STUDENTS

Background: Aggressive periodontitis, characterized by a rapid progression of periodontitis in the absence of a large amount of plaque and / or tartar, affects healthy individuals under 30 years of age. The aim of the study was to determine the frequency of aggressive periodontitis among high school students. Place and Duration: In the Department of Dentistry, Punjab Dental Hospital Lahore for one-year duration from April 2019 to April 2020. Methods: 780 high school students were randomly selected. The probing depth was examined in each of them in 6 places of permanent incisors and first molars. People presenting with pocket depressions> 4.5 mm in more than one tooth were asked to participate in the next phase of the study, in which vane and periapical images were taken. People with radiographic evidence of bone loss received complete clinical and radiographic examinations. The frequency of aggressive periodontitis was determined. Fisher's exact test was used to determine significant 4 differences between the sex groups. Data analysis was performed using SPSS version 18. Results: Of the 780 patients initially examined, 39 had probing depths> 4.5 mm. Thirty-four of these people reported for further tests, which resulted in the diagnosis of local aggressive periodontitis in 6 (0.77%), 4 girls (0.86%) and 2 boys (0.63%). There were no significant differences between boys and girls. We found no cases of generalized aggressive periodontitis. Conclusion: The results of this study showed that in 0.77% of the studied population, localized aggressive periodontitis was diagnosed. This number is similar to the number reported for European and North American populations.
