Periodontal treatment needs in a native island community in Colombia determined with CPITN

AIMS: To identify the prevalence and different degrees of periodontal disease in an isolated community (Isla Grande, Colombia) with no dental services and low educational level with the use of CPITN, and to establish periodontal treatment needs in different age groups. RESULTS: Of 116 people examined, 0.9% were in periodontal health (CPITN value 0), 18.1% had gingival bleeding (CPITN value 1), 51.7% had supra or subgingival calculus (CPITN value 2), 18.1% presented pockets 3.5-5.0 mm deep (CPITN value 3), and 11.2% had pathological pockets of 5.5mm or deeper (CPITN value 4). No clear differences were observed between sexes. CONCLUSIONS: This study shows that 81% of the sample has some type of periodontal treatment need, with 69.8% of them requiring periodontal treatment that may be supplied by a hygienist and 11.2% requiring specialised treatment. Implementation of oral health education and oral prevention programmes was recommended to the authorities for this community.
