The purpose of the study was to investigate whether tooth mobility affected on response of periodontal pockets following non-surgical periodontal therapy. Twenty patients with moderate to advanced periodontitis were selected. The following clinical parameters were recorded by five examiners ; probing pocket depth (PPD), probing attachment level (PAL), tooth mobility and bleeding on probing (BOP). Non-surgical treatment consisted of plaque control, scaling and root planing was performed. All teeth were divided into two groups of slight mobility group (Miller's Index : 0, 1) and severe mobility group (Miller's Index : 2, 3). Furthermore, for each groups, all sites were classified into three severity categories according with initial PPD : PPD≦3mm, 3mm<PPD≦6mm, 6mm<PPD The amount of change of PPD and PAL for each pockets were compared between two groups. The results showed that the slight mobility group, compared with severe mobility group exhibited significantly greater amount of reduction of PPD and gain of PAL. It was suggested that tooth mobility affected on healing response of periodontal pockets following non-surgical treatment.
