Microbiological study of localized juvenile periodontitis in Panama.
The occurrence of subgingival Actinobacillus actinomycetemcomitans and Capnocytophaga in 12 localized juvenile periodontitis and 10 gingivitis patients from Panama was determined using selective culture techniques. A actinomycetemcomitans was present in all localized juvenile periodontitis lesions studied and was, on average, recovered in hundred-fold-higher numbers from localized juvenile periodontitis lesions than from gingivitis lesions. Capnocytophaga was only recovered in approximately threefold-higher numbers from localized juvenile periodontitis than from gingivitis. The study confirms and extends previous data indicating a close relationship between A actinomycetemcomitans and localized juvenile periodontitis. It is proposed that identification of A actinomycetemcomitans may be a valuable adjunct in the diagnosis of localized juvenile periodontitis.
