Patient preference regarding 4 types of periodontal therapy following 3 years of maintenance follow-up.

It has been shown that certain types of periodontal therapy result in greater post-therapy gingival recession. It has been suggested that this recession may lead to maintenance complications for patients. This study evaluated patient perceptions 3 years following the completion of 4 types of periodontal therapy (coronal scaling (CS), root planing (RP), modified Widman surgery (MW), and flap with osseous resectional surgery (FO)). 75 individuals completed split-mouth therapy and 3 years of maintenance follow-up. An interview survey of all patients categorized their perception for each treatment of their mouth concerning difficulty in cleaning, sensitivity to temperature, general "feeling" of the region, prevalence of localized symptoms, food retention, comfort of oral examination, and attitude toward repeating therapy. Responses to questions showed no statistically significant differences between treatment regions. Patterns demonstrated that FO-treated regions were perceived to have less food retention, but were more difficult to clean. It was generally found that at the end of 3 years of maintenance, patients felt their mouths were "normal", they experienced few localized symptoms, and were very willing to repeat any of the treatment regimens if necessary.
