Meta-analysis of the effectiveness of educational interventions on dental and oral health promotion in Iran

Evaluation of peer role models as oral health education providers among school children in Mysuru, Karnataka, India

BACKGROUND

India lacks organized school oral health programs, resulting in limited access to oral health care among children. The peer role models, or teachers, may help in bridging the gap to enhance knowledge on self-care preventive practices. The aim of the study was to evaluate and compare the effectiveness of dental health education (DHE) offered by qualified dental professional, trained teachers, and peer role models in promoting oral hygiene status and behavior among school-going children in Mysuru, Karnataka.

MATERIALS AND METHODS

This was an interventional study conducted over a period of 3 months in an academic year in three selected schools in Mysuru City, India. A total of 120 students were divided into three groups - group 1 were given DHE (dental health education) by a dental professional, group 2 were given DHE by a trained teacher, and group 3 were given DHE by peer role models. Oral health knowledge was assessed using a close-ended questionnaire, plaque levels were assessed using Turesky Gilmore Glickman modification of Quigley Hein plaque index, and gingival status was assessed using Loe and Sillness gingival index. After 3 months, the same index and questionnaire were used post intervention.

RESULTS

The mean scores for knowledge on dental caries at baseline in groups 1, 2, and 3 were 3.75 ± 1.25, 3.65 ± 1.07, and 3.40 ± 1.17, respectively, with no significant difference between the groups, which changed to 4.43 ± 1.27, 3.37 ± 1.14, and 4.93 ± 0.99, respectively, following intervention. Similar results were observed with regard to knowledge on gingival and periodontal diseases. The mean plaque scores at baseline for groups 1, 2, and 3 were 4.17 ± 0.30, 3.24 ± 0.70, and 4.10 ± 0.31, respectively, which changed to 3.85 ± 0.32, 3.90 ± 0.39, and 3.69 ± 0.34, respectively, in three groups following intervention. Post intervention, plaque scores and gingival scores significantly improved in groups 1 and 3 but worsened in group 2. Overall, knowledge scores improved in groups 1 and 3 for some questions, but improvement was not noted in some questions.

CONCLUSION

Under the limitations of the study, it was found that peer role models were as effective as dental professionals in providing DHE in schools.

Unleashing the most effective oral health education intervention technique for improving the oral hygiene status and oral health knowledge in visually impaired young individuals: A systematic review and meta-analysis

Appropriate oral health education (OHE) plays a vital role in prevention of oral diseases and would bridge the gap between dentists and visually impaired individuals. Hence, this systematic review was planned with an aim to evaluate effectiveness of various OHE techniques on the oral hygiene status and oral health knowledge of visually impaired young individuals. An electronic search extended to September 30, 2020 was conducted on PubMed, Wiley, ProQuest, ScienceDirect, Cochrane library, EBSCO, and Google Scholar. Two independent reviewers assessed the studies using a two-stage process; data were extracted according to PRISMA statement. Risk of bias assessment of selected studies was executed according to the study designs. Meta-analysis using the random-effects model was conducted for the outcomes for all oral health education techniques using STATASE 16.1 software. Hand and electronic search identified 3829 articles. After screening for titles and duplicates, 37 articles were retrieved, which were screened through abstract and full text. Of the 37 articles, 17 articles were included for qualitative synthesis, and out of that, 13 were for meta-analysis. Ten variations in oral health education (OHE) techniques were used in the included 17 studies to impart oral health education to visually impaired young individuals. Overall, all OHE techniques demonstrated a positive impact on oral hygiene status. The pooled overall cumulative mean difference of the oral hygiene status after imparting education in ATP, Audio, and Braille was 1.33 [1.06, 1.59], 1.76 [1.11, 2.42], and 1.96 [1.40, 2.55], respectively. An appropriate OHE technique boosts confidence in visually impaired young individuals, making the learning process an enjoyable experience. Use of either Braille or the ATP OHE technique was found to be a reliable and useful method to improve oral hygiene of visually impaired young individuals.
