The aim of this retrospective study was to assess the outcomes of non-surgical and surgical mechanical root debridement for the treatment of infrabony defects and explore potential prognostic factors. Treated infrabony defects followed for at least 1 year were selected. All data pertaining to the clinical outcomes were recorded. Multi-level regression analysis and Cox Proportional-Hazards Models were used to assess the immediate (3–6 months) clinical outcomes, survival of the treated teeth, and factors influencing these results. 132 patients were included in the analysis. The analysis showed 1.42 ± 1.71 and 2.23 ± 1.64 mm in pocket depth (PD) reduction, 0.13 ± 1.83 and 0.08 ± 1.76 mm in clinical attachment level (CAL) gain, and 1.29 ± 1.56 and 2.15 ± 1.33 mm increase in gingival recession (REC) for the non-surgical and surgical groups, respectively. The 5-year survival rates were 93% for the non-surgically and 90% for the surgically treated teeth. Several factors affected clinical outcomes and tooth survival. Within its limitations, the treatment of infrabony defects with non-surgical and surgical mechanical root debridement was found to result in moderate but significant PD reduction, nevertheless, this may also be attributable to the resultant REC.
