BackgroundWeaknesses in toothbrushing performance can be seen when young adults are instructed to perform habitual toothbrushing. Nothing is known about toothbrushing behavior when instructed to perform to the best abilities. The present study analyzes such behavior and compares it to habitual behavior.MethodsA random sample of N = 98 young adults born in 1995 was examined in 2014/2015.They were asked to perform oral hygiene to the best of their abilities in front of a camera. Videos were analyzed regarding details of brushing behavior. A quality index was developed which describes the extent of the neglect of brushing on palatinal and vestibular surfaces. Data were compared to those of an earlier study of young adults (born in 1992, examined in 2011, N = 101) who were asked to perform oral hygiene as they habitually do.ResultsThe 1995 cohort (best abilities) brushed their teeth significantly longer than the 1992 cohort (habitual brushing). This was due to significant longer brushing at vestibular and occlusal surfaces. Neglect of palatinal surfaces was similar in both cohorts. Groups did not differ regarding brushing movements. 40% of the brushing time on lateral surfaces was spent with scrubbing movements despite opposing advice in common oral hygiene instructions.ConclusionsToothbrushing to the best of one’s abilities might still not be good enough. Young adults apparently lack a reasonable concept of what is meant by high quality toothbrushing. More efforts should thus be undertaken to explain them (and adults) this concept.Electronic supplementary materialThe online version of this article (10.1186/s12903-018-0633-0) contains supplementary material, which is available to authorized users.
Background Research indicates that adolescents may have difficulties to adopt the tooth brushing recommendations delivered in prophylaxis programs. However, it is not clear whether these difficulties are seen amongst the entire age range of adolescence (10–19 years) or only occur at certain developmental stages of the adolescence. The present study analyzes the tooth brushing performance of adolescents and compares it to the best-practice of tooth brushing demonstrated during prophylaxis programs. Methods A random sample of N = 66 adolescents, comprising 10-year-olds (n = 42) and 15-year-olds (n = 24), were asked to perform oral hygiene to the best of their abilities in front of a tablet camera. Videos were analyzed for tooth brushing duration, location, and brushing movements, and the difference between the actual and expected behaviour was tested for consistency using repeated measures ANOVAs and Student’s t-tests. For the direct comparison across different age groups, already available data from 12- and 18-year-olds were reanalysed. Results The average brushing time (mean ± SD) of the 10-year-olds and 15-year-olds was 195.8 s (74.6 s) and 196.1 s (75.8 s), respectively. Regardless of age, the adolescents distributed their brushing time unevenly across the inner, outer and occlusal surfaces. The inner surfaces in particular were neglected to a considerable extent, as no age group spent more than 15.8% of the total brushing time on them. Furthermore, all age groups showed a high proportion of horizontal movements on the inner and outer surfaces, regardless of the movements instructed for the respective surfaces. Conclusion Even if adolescents brush to the best of their abilities, they neglect or skip one or many of the tooth surfaces. The reasons for the lack of compliance to tooth brushing instructions are discussed in light of the methods used in prophylaxis programs and the influence of parents.
Objectives: Previous studies have shown high levels of dental plaque after toothbrushing and poor toothbrushing performance. There is a lack of evidence about what oral hygiene behavior predicts persistent plaque. The present cross-sectional study thus relates toothbrushing behavior to oral cleanliness after brushing and to gingivitis. Methods: All young adults from a central town in Germany who turned 18 y old in the year prior to the examination were invited to participate in the study. They were asked to clean their teeth to their best abilities while being filmed. Videos were analyzed regarding brushing movements (vertical, circular, horizontal, modified Bass technique) and evenness of distribution of brushing time across vestibular (labial/buccal) and palatinal (lingual/ palatinal) surfaces. Dental status, gingival bleeding, and oral cleanliness after oral hygiene were assessed. Results: Ninety-eight young adults participated in the study. Gingival margins showed persistent plaque at 69.48% ± 12.31% sites (mean ± SD) after participants brushed to their best abilities. Regression analyses with the brushing movements and evenness of distribution of brushing time as predictors explained 15.2% (adjusted R 2 = 0.152, P = 0.001) of the variance in marginal plaque and 19.4% (adjusted R 2 = 0.194, P < 0.001) of the variance in bleeding. Evenness of distribution of brushing time was the most important behavioral predictor. Conclusion: Even when asked to perform optimal oral hygiene, young German adults distributed their brushing time across surfaces unevenly. Compared with brushing movements, this factor turned out to be of more significance when explaining the variance of plaque and bleeding. Knowledge Transfer Statement: Results of this study can help clinicians and patients understand the meaning of specific behavioral aspects of toothbrushing for oral cleanliness and oral health.
Background Research in adolescents reveals that they are not capable to remove dental plaque effectively. Inconsistent application of brushing techniques and neglect of certain areas while brushing are very common. As parents play a major role in the oral health education, the present study aimed to examine and describe the tooth brushing performance of the parents of adolescents. Methods Parents of adolescents (N = 66) were asked to perform oral hygiene to the best of their capabilities in front of a video camera and dental plaque was recorded before and afterwards. Papillary bleeding was also assessed. Results The tooth contact time (i.e. net brushing duration) averaged 155 s ± 58 s. Gingival margins showed persistent plaque at 68% ± 14% of the sections assessed. Papillary bleeding was found at 52% ± 18% of the papillae. Parents brushed inner surfaces lesser than the outer surfaces (41 s ± 24 s vs. 73 s ± 33 s) and 29% of the parents completely missed the inner surfaces of at least one sextant. On the outer surfaces parents predominantly applied circular movements (66% ± 25% of brushing time). Vertical brushing prevailed on the inner surfaces (52% ± 30%). However, horizontal scrubbing was also very common (46% ± 31%). Conclusions Parents’ tooth brushing performance was neither effective in terms of plaque removal nor did they fully comply with tooth brushing recommendations such as considering all inner surfaces when brushing or application of other than horizontal movements to lateral surfaces. Regarding oral hygiene, parents should not only be a good role model in terms of timing, frequency and duration of tooth brushing but should also be able to demonstrate how to brush teeth completely and effectively. The current research indicates that they might lack the latter skill.
BACKGROUND Analyzing recommendations on websites is a method that is often applied to understand what advice is given to patients. An important health behavior which is carried out by most people on a regular basis is toothbrushing. OBJECTIVE Our objective was to assess toothbrushing recommendations on German websites. METHODS It was planned to include websites related to oral hygiene in German language and to analyze their recommendations quantitatively by counting them regarding frequency, duration and toothbrushing technique. RESULTS Several obstacles emerged during the study which finally rendered a quantitative analysis impossible. Among them are an unreasonable amount of websites fulfilling the inclusion criterion, multiple and contradictory advice within one and the same internet presence and cross-linking between websites. Further, it was impossible to clearly define what should be considered a recommendation and if it would be found by patients as some potential recommendations were mentioned just by the way or at unusual parts of the website. CONCLUSIONS Lessons learned during this analysis are discussed with respect to the present research question but also to other research on health recommendations on the internet. Problems that might occur during quantitative and qualitative analyses are shown and potential solutions are presented along with the biases they might cause. Thereby a checklist is provided which should be considered when planning, reporting and evaluating studies analyzing web contents.
