Muco-gingival and periodontal health recovery following reimplantation of teeth

Reimplantation of avulsed permanent teeth following traumatic injuries is a widely accepted therapeutic measure; however, though periodontal healing i s considered to be the major determinant of long-term survival of reimplant ed teeth, the mucogingival reaction to reimplantation has never been assess ed. In the present study, hygiene level and gingival inflammation of 13 rei mplanted teeth were assessed according to the plaque index (PI) and the gin gival index (GI) around both reimplanted and control teeth. The periodontal condition was evaluated by measuring probing depth and probing attachment level at the same location. The clinical parameters of the reimplanted teet h were compared with those of contralateral teeth with the help of the non- parametric Wilcoxon signed ranks test. There were no statistically signific ant differences in PI and GI scores at any points of measurements around bo th reimplanted and control teeth; neither did probing depths and probing at tachment levels differ between reimplanted and contralateral teeth. The res ults of the present study indicated that the muco-gingival reaction followi ng traumatic avulsion did not affect the long-term prognosis of the reimpla nted teeth.
