Occurrence of periodontitis in an urban adolescent population.
The presence of periodontitis in 307 black, Hispanic, and Asian students age 12 to 15 years was evaluated by calibrated examiners in a Los Angeles inner city junior high school. The periodontal status of maxillary and mandibular incisors and permanent first molars was evaluated using the Plaque Index, probing depth, attachment loss, bleeding on probing, tooth mobility, presence of calculus, and caries. Thirty-nine (12.7%) of 307 students had 5 mm or deeper probing depths and associated attachment loss of at least 2 mm and were considered to have periodontitis (PD). The PD group had significantly more bleeding, calculus, and missing teeth than the non-PD group, but both groups had moderate to severe plaque accumulation. The distribution and severity of disease increased with age. Deeper probing depths were associated with the molar teeth and six (15.4%) of the 39 subjects in the PD group had furcation involvement. Clinical screening alone was not sufficient to determine if the periodontitis seen was localized juvenile periodontitis; however, the program detected a high occurrence of periodontitis in this population group.
