Rolling or Vertical Is Inefficient Tooth-brushing Method – Video Observation Study
Objectives: The study aimed to measure the plaque removal effect of the rolling or vertical method comparing to other tooth-brushing methods in Korea.
Methods: This study was conducted with the approval of the Institutional Review Board (IRB) of the Seoul National University School of Dentistry (IRB Number 2018-0021). Participants (n=30) between the ages of 19 and 30 without periodontal disease were enrolled this observational study. The same toothbrush and toothpaste were given to participants and they were asked to brush their teeth as usual. During brushing, participants were recoded with a camcorder (Go pro6, GOPRO Inc., California, USA) which attached to the mirror, and they already knew that they were recorded. After tooth-brushing, the dental plaque staining and oral plaque index (PI) examination were performed and the plaque index score was measured by the Turesky modified Quigley Hein Index. Brushing methods were classified as rolling, horizontal, vertical, circling, oblique and skipped surfaces were recorded separately. Statistical analysis was performed at the end of study using SPSS program (SPSS 25.0, IBM Inc., New York, USA).
Results: The most of all surfaces of the mouth were skipped and most common method is the circling method, followed by vertical, horizontal, rolling, and oblique method. The most commonly used method in the vestibular surface was circling and 52.92% of the oral surface was skipped. The mean PI score of the surfaces of brushing with oblique method showed the lowest mean ± SD 1.73±0.82, followed by circling and horizontal method. The mean PI score in the skipped surfaces (mean ± SD 2.52±0.81) were highest of all surfaces.
Conclusions: This study suggested that rolling or vertical brushing method is inefficient tooth-brushing method comparing to other methods.
