The Effect of Tooth Mobility on Response of Periodontal Pockets following Non-surgical Periodontal Therapy

Abstract

Kyusyu Dental College ， Kitakyusyu ， JapanThe 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 ． AU teeth were divided into two groups of slight mobihty group ( Miller ' s Index ： 0 ， 1) and severe mobility group ( Mnler ' 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 ．
