Abstract
PURPOSE: This randomized clinical trial investigated the influence of the utilization time of brush heads from different types of power toothbrushes [oscillating rotating (OR) and sonic action (SA)93; on oral hygiene (plaque accumulation and gingival inflammation) over a 6-month observation period. METHODS:49 participants were randomly allocated into two groups: use of the same brush head over 6 months (NR: non-replacement) or replacement of brush head every 4 weeks over 6 months (R: replacement). Each group was subdivided into two subgroups according to kind of toothbrush (TB) used (OR and SA). Modified Quigley-Hein plaque index (QHI), papilla bleeding index (PBI), and gingival index (GI) were recorded at baseline and 2, 8, 12, 16, and 24 weeks after baseline. After 24 weeks, participants of both groups (R and NR) received a new brush head. At week 26, final QHI, PBI, and GI were recorded. RESULTS:QHI decreased between baseline and follow-up visits in R groups (P< 0.05), with the exception of week 12 (P= 0.26). In NR groups, no significant decrease was detected (P> 0.05). There was no significant effect of time on PBI or GI in any of R subgroups (P> 0.05). In NR oscillating/rotating TB: significant increase in PBI and GI was detected 24 weeks after baseline (PBI: P= 0.02, GI: P= 0.03); sonic action TBs showed significant decrease in PBI at every follow-up visit (P< 0.05), except at 24 weeks after baseline (P= 0.73). GI was significantly decreased at 2 weeks after baseline only (P< 0.01). CLINICAL SIGNIFICANCE: Six-month use of the same brush head reduced effectiveness in removing plaque, and gingival inflammation appeared to increase after a utilization time of over 4 months. Replacing brush heads is advised after 4 months.
