The aim of this study was to determine how the removal non-impacted third molars (N-M3s) affects periodontal status neighboring second (M2s).The condition M2s for which N-M3s were removed (more than 6 months previously) and those with intact analyzed in a cross-sectional observation study. In an additional case series, changes response adjacent N-M3 observed during 6-month follow-up period.A total 457 patients 1,301 enrolled observational Compared N-M3s, without (teeth more exhibited 0.27-mm reduction average pocket depth (PD) (p < .001) 0.38-fold reduced risk at least one probing site PD ≥5 mm (PD5+) .001). Subsequently, 41-case showed that after extraction, decreased by 0.31 .001), while incidence PD5+ 21.9% when compared parameters detected before tooth extraction = .004).Removing associated improved M2s.
