title: Effect of benign familial neutropenia on the periodontium of Yemenite Jews.
abstract: The purpose of this study was to compare the periodontal status of Yemenite Jews with and without benign familial neutropenia (BFN). Thirty-four volunteers were examined at baseline and after 3 years. Plaque index (PlI), bleeding index (BI) probing depth (PD), and attachment levels (AL) were recorded. Differential blood counts were done on at least three occasions during the study. Volunteers with at least one count of less than 2000 neutrophils were considered neutropenic. The majority of patients received oral hygiene instructions and scaling at the initial visit. During the study there was a significant drop in PlI (P less than 0.01) and BI (P less than 0.05). At baseline the BFN and non-BFN volunteers had similar PlI, but the BI was significantly greater in the BFN group. At follow-up, there was a significantly greater number of teeth with pockets greater than or equal to 6 mm in the BFN group (P less than 0.05). These results indicate that volunteers with BFN, a phenomenon that has not previously been associated with any pathology, are more susceptible to gingival inflammation and attachment loss than unaffected volunteers and that they respond more favorably to an improvement in oral hygiene.
