Higher OHIP scores indicate lower OHRQoL. The range of T10 is 1-3 years. A correlation was found between the duration of surgery and the OHIP score on the first 7 days after surgery (r = 0.3 - 0.4, P < .05). The longer the surgery, the higher the OHIP score in the first week. No significant correlation was found between age, gender, blood loss, or OHIP score. The Friedman test was used to assess the mean OHIP scores over baseline (T0) and the first 7 days after surgery (T1-T7). The overall P-value < .00 indicates a significant overall difference in mean OHIP scores between the first 7 days. The mean OHIP score increased from T0 to T1 but tended to decrease from T1-T7. A post hoc pairwise comparison indicated that the OHIP score from T1-T6 was significantly higher than at T0, but there was no significant difference between T0 and T7 (Table 3).
