[Prevalence and risk factors of aggressive periodontitis in schoolchildren in the eastern district of Syria]

ABSTRACT

Aggressive periodontitis [AgP] is one of the periodontal diseases which affects systemically healthy individuals usually under the age of 30. The disease is characterized by a rapid attachment loss and destruction of alveolar bone. The aim of the present study is to assess the prevalence of [AgP] among schoolchildren in the eastern districts of Syria and to investigate the role of some and risk factors and determinants. In a cross sectional study, a random sample of 1200 students was drawn [568 males and 614 females] aged from 12-20 years [mean=16 years] from Deirezzor and Al-hasakah govrnorates in the eastern districts of Syria. Students completed a written questionnaire for determinants [age, gender, race] and risk factores [oral hygiene, smoking,soci-economic and education level] for [AgP], and have been examined according to [CPITN] by WHO probe, Gingival recession[GR], Probing Pocket Depth[PPD] and simplified oral hygiene[OHI-S] indices. Students who exhibited clinical attachment loss [CAL] >/= 4 mm at one or more tooth surface were scheduled for further periodontal examination. [AgP] was diagnosed according to the AAP classification 1999. chi-square test was used at P students with [AgP] was 69 students, that is 5.8% of the sample [the precentage of localized aggressive periodontitis [LAgP] and generalized aggressive periodontitis [GAgP] were, respectively, 0.4% and 5.4%]. Al-hasakah had the highest precentage of [AgP] 6%, followed by Deir ezzor 5.6%. The first molars were the most affected teeth with precentage [20.8%], followed by second premolars [16.2%] and second molars [15.1%], wherease central incisors were the least affected [10%]. Dental plaque, parental low educational level, and the high number of siblings[more than 8] showed a significant relationship with [AgP]. There is a high prevalence of [AgP] in the eastern district of Syria with special disease pattern. Bacterial plaque, parental low education level and high number of siblings were important risk factors in this district
