PERIO - Periodontal Practice Today 3 (2006), Nr. 4 28. Nov. 2006
Aggressive periodontitis (AP) is a distinct type of periodontitis previously termed early-onset periodontitis (EOP). Risk factors of AP are numerous but have not been studied in Jordanian adults. The aims of this study were to investigate the relationship between a number of risk indicators and AP, and to compare risk indicators of aggressive and chronic periodontitis (CP). The sample consisted of 195 patients (109 AP and 86 CP patients) attending Jordan University of Science and Technology (JUST) Dental Teaching Centre. Approximately 75% of subjects with AP were females and 25% were males. The majority of AP patients were >=35 years of age, not working, had a family income <625 Euro/month (<500 JD/month), lived in rural areas, and had completed secondary education only. There was a statistically significant difference (p <0.05) between AP and CP patients with regard to age, frequency and duration of brushing, and to type, quantity and duration of smoking. Approximately 61% of AP patients reported presence of periodontal problems among other family members and approximately 41% of them had consanguineous parents, but these were not statistically significant when compared with the CP group. The percentages of mean clinical attachment level (CAL) >3mm, mean CAL >5mm, and mean pocket probing depth were statistically different between AP and CP groups. We conclude that young age, not smoking, reduced oral hygiene measures, income <625 Euro/month, urban residency and regular attendance to dental/periodontal clinics are associated with increasing risk of AP. However, it appears that the impact of these environmental risk factors is less in AP than in CP.
