Significant differences in TLR were found between levels 3 and 5 ( p < 0.001) and levels 4 and 5 ( p < 0.001), while the difference between 3 and 4 was of borderline significance ( p = 0.053).
Significant differences in TLR were found between levels 3 and 5 ( p < 0.001) and levels 4 and 5 ( p < 0.001), while the difference between 3 and 4 was of borderline significance ( p = 0.053).
Although the difference did not reach statistical significance (probably due to the limited size of the non-compliers sample and the high data dispersion within the latter), this finding seems to indicate that the lack of adherence with a SPC program based on a 3–4-month interval may further accelerate the rate of tooth loss in patients at high risk.
