Development and evaluation of the “Toothbrushing Timer with Information on Toothbrushes” application: A prospective cohort pilot study

Abstract

ObjectivesFor people, it is challenging to be conscious of the appropriate toothbrushing time to maintain good oral health in daily life. The aim of this study was to preliminarily examine the utility of an application (app) that combines a toothbrushing timer and information on toothbrushes.Materials and MethodsWe developed the “Toothbrushing Timer with Information on Toothbrushes” app to help users ensure appropriate toothbrushing time and learn about the beneficial characteristics of toothbrushes. A total of 18 participants were registered for the study. At baseline (T0) and after 1 month (T1) of app usage, study participants answered a digital questionnaire that comprised three questions on oral health practice, self‐efficacy in oral hygiene, and quality of life related to oral health (Oral Health Impact Profile‐14 [OHIP‐14]).ResultsFive participants were excluded from the analysis as they did not answer the digital questionnaire. Finally, 13 participants completed the survey with a follow‐up of 1 month. The 13 participants were grouped into health professionals (n = 8) and non‐health professionals (n = 5). The total scores for oral health practice and self‐efficacy related to oral hygiene increased after a month of app usage in health professional and non‐health professional groups. However, there were no significant differences between T0 and T1 in either group. The total score of OHIP‐14 was lower at T1 than at T0 in both groups. Therefore, participants showed better oral health practice, self‐efficacy in oral hygiene, and quality of life related to oral health at T1 compared with that at T0.ConclusionsOur app showed positive results for the users and is useful in maintaining and promoting oral health awareness and practice. However, our pilot study lacks sufficient power and did not yield significant differences. Therefore, high‐quality clinical trials with larger sample sizes are warranted for further improvement and evaluation.

Relationship of oral bacterial number with medical hospitalization costs in analysis of Diagnosis Procedure Combination database from single institution in Japan

“…Reducing the number of oral bacteria in patients affected by those conditions may result in decreased hospitalization costs. Dental plaque removal by daily toothbrushing and oral health awareness are important factors for maintaining good oral hygiene 44,45 . Oral care has also been shown to prevent the incidence of perioperative complications in patients undergoing various cancer treatments and surgery under general anesthesia 46,47 , and can reduce the risk of onset of ventilator-associated pneumonia in patients in an intensive care unit 48 .…”

Wisdom Tooth Autotransplantation for the Missing Maxillary Central Incisors Using a 3D-Printed Replica: A Case Report

“…Then, as the patient had the deep curve of Spee, flattening the lower dental arch was performed by orthodontic treatment to distribute masticatory forces. Moreover, the patient received professional tooth brushing instructions for dental plaque removal to maintain good oral hygiene including the autotransplanted tooth [ 9 , 10 ].…”

The prevalence of oral herpes simplex virus type 1 and its association with oral hygiene and periodontal condition

“…Oral hygiene practice (i.e., regular toothbrushing with a correct brushing technique, appropriate toothbrush, and adequate brushing time) is required to maintain good oral hygiene [8,9]. It is speculated that inadequate oral hygiene practice causes inflammation in periodontal tissues.…”
