Passarelli PC, et al. - Researchers estimated 89 individuals to study the healing and periodontal status of mandibular second molars (M2) after the surgical extraction of third molar (M3). They observed improvement in 6-month M2 probing pocket depth (PPD) at disto-vestibular [basline (T0)-5.2/6-months (T1)-3.0 mm] and disto-lingual (T0-5.4/T1-3.2 mm) sites. Significant clinical improvements were noticed in bleeding on probing (BOP), plaque index (PI), and gingival index (GI) after extractions. They observed a correlation of older age (mean 55 years) and mean distal PPD at baseline of 7 mm with PPD ≥ 4 mm 6 months postextraction. They also suggested the history of periodontitis, preoperative deep pockets, and older age as the independent risk factors for poorer healing and residual pockets after M3 surgical extraction.
