Effects of SRP Plus Oral Hygiene in Stage I/II Periodontitis
Objectives: To compare the effects of scaling and root planing followed by powered or manual toothbrushing, on periodontitis symptoms and plaque levels, up to 6 months.
Methods: This was an IRB-approved, randomized, single-blind parallel-design study. Eligible subjects were aged 18-75 years with Stage I or II periodontitis. Eligible subjects received in-office scaling and root planing (SRP) and were then randomized to twice daily home use of either a manual toothbrush (MTB) or Philips Sonicare power toothbrush (PTB), for maintenance care. Randomization was balanced for gender and periodontitis stage. All other oral hygiene aids were prohibited. Subjects returned to clinic for monthly assessment of Probing Pocket Depth (PPD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP) and Modified Plaque Index (MPI), until Month 6.
Results: There were 328 subjects enrolled and randomized. Of these, 299 subjects completed the study, 149 in the PTB group, and 150 in the MTB group. The Mean(SD) age of subjects was 44.1(13.2) years. At Month 6, statistically significant differences were observed between groups, for all measures. In particular, for PPD, LS Mean(SE) percent reduction from baseline outcomes were 11.16%(0.39) for PTB, and -3.00%(0.38) for MTB, p-value <0.0001. For BOP, percent reduction outcomes were 54.55%(2.53) for PTB, and -1.06%(2.52) for MTB, p-value <0.0001.
Conclusions: Following scaling and root planing, daily home oral hygiene maintenance with a powered toothbrush significantly improved periodontitis symptom status (PPD, CAL, BOP) and plaque levels, compared to daily use of a manual toothbrush, in a Stage I/II periodontitis population. Both products were safe for use.
