Periodontitis in a 13-year old: an illustration of a new periodontal classification.

This report describes a periodontal abscess and bone loss in a 13-year-old boy being treated as a patient in the Dental Benefit Scheme, a year after his entry to the Scheme. His condition illustrates well the rationale of a new classification for periodontitis. We suggest that periodontal screening is important so that instances such as this can be identified earlier; a small number of young patients require conventional, conservative periodontal treatment and ongoing monitoring of periodontal disease.
