RESUMO
INTRODUCTION: Proper tooth brushing is a complicated process for children. Therefore, the aim of this study was to investigate the effect of differential learning to improve tooth brushing in children. METHODS: In this prospective, controlled, single-blinded, randomized clinical trial, 58 children between 3 to 8 years of age (mean: 5.7±1.5 years; 29 female) were randomly assigned to test or control group through the child's self-drawing of an unlabeled envelope from a box. All children received oral hygiene instructions and information in these sealed envelopes and were asked to follow the corresponding instructions at home for 28 days. Children in the test group received instructions with exercises using the differential learning method, whereas the children in the control group received the usual tooth brushing instructions. RESULTS: At baseline and planned follow-ups after 4 and 12 weeks, plaque and gingival indices (QHI, PBI) were recorded in both groups by 2 calibrated and blinded investigators. At baseline, there were no significant differences between the test and control groups regarding plaque and gingival indices (QHI: 4.1±0.5 vs. 4.1±0.4; p=0.7; PBI: 0.6±0.3 vs. 0.6±0.3; p=0.7). At the 1st and 2nd follow-up, both groups showed improved oral health indices, but there was an overall better improvement in the test group. While the difference in gingival indices was statistically significant in the 1st recall (PBI/test: 0.1±0.2 vs. control: 0.3±0.2; p<0.001), the difference in plaque indices was not (QHI/test: 2.1±0.9; control: 2.6±0.9; p=0.07). At the 2nd recall (mean week=19.5 weeks), the test group showed statistically significant and clinically relevant better oral health indices than the control group (2nd recall, QHI/test: 2.1±0.9 vs. control: 3.2±1; p<0.001; PBI/test: 0.1±0.2 vs. control: 0.5±0.2; p<0.001). CONCLUSION: In conclusion, differential learning leads to oral hygiene improvement in children with high caries risk and initially poor oral hygiene, which was superior to the conventional learning method through repetition in the medium term.
RESUMO
BACKGROUND: Early childhood caries (ECC) remains a major global health problem. Various measures to prevent it have been implemented in the past, including those using digital applications. AIM: To evaluate the acceptance and efficacy of a digital application (FU-APP) based on evidence-based caries control recommendations for parents of children aged 6-72 months. METHODS: Part 1, prospective questionnaire-based survey to test FU-APP (usage, acceptance, content information, usefulness, and satisfaction) filled out by parents (n = 22); Part 2, two-armed (test n = 20; control n = 23) care-based, randomized controlled trial, where the test arm received instructions verbally and via FU-APP, and the control arm received them only verbally. At baseline and follow-up (4 weeks), intraoral clinical indices (plaque index-API and caries-dmft) were recorded. RESULTS: FU-APP was considered by parents to be a suitable tool for gaining knowledge about oral health practices for their children (all criteria >86%). No differences in the dmft levels were expected. However, API was significantly better at the follow-up in the test-arm (p = 0.01), with no differences in the control-arm (p = 0.72). CONCLUSION: A digital application can serve as an innovative tool to promote evidence-based oral hygiene recommendations among parents of children to control ECC. Its long-term usability and functionality should be tested.
RESUMO
Background and Objectives: Silver diamine fluoride (SDF) has been incorporated into the treatment of dental caries in children, mainly in countries with high caries prevalence. In Europe, however, SDF started to gain popularity during the COVID-19 pandemic. This study aimed to investigate the efficacy of SDF and to evaluate dentists'/parents' acceptance of SDF use in paediatric patients treated in a German university setting. Materials and Methods: A retrospective analysis of all patients treated with SDF between 2017 and 2020 was carried out. Only teeth with no reported clinical/radiographic evidence of irreversible pulpal inflammation were included. The outcome measures were success, minor failures (caries progression, reversible pulpitis) and major failures (irreversible pulpitis, abscess). The treatment acceptance by dentists and the parents of SDF-treated children was cross-sectionally evaluated using questionnaires. Descriptive statistics and Kaplan-Meier survival analysis were performed. Results: A total of 93 patients (mean age 5.3 ± 2.9 years) with 455 treated teeth (418 primary/91.9%; 37 permanent/8.1%) were included and followed up for up to 24 months (19.9 ± 10.5 months). SDF was used for dental caries (98.2%) and hypersensitivity relief on MIH teeth (1.8%). Most teeth did not show any failure (total success 84.2%). A total of 5 teeth (1.1%) showed minor failures, and 67 teeth (14.7%) showed major failures (p = 0.001). Success/failure rates were not affected by patient compliance, gender, dentition, or operator (p > 0.05). In total, 30 questionnaires were collected from parents (mean age 36.8 ± 6.4 years). SDF was applied on anterior (n = 2/6.7%), posterior (n = 15/50%) and anterior/posterior teeth (n = 13/43.3%). At the 1-week follow-up, 80% of parents noticed black teeth discoloration. Treatment satisfaction was higher for posterior (95.2%) than for anterior teeth (36.4%; p < 0.001). In the 27 responses from clinicians, SDF was generally considered a viable option in paediatric dentistry (n = 23; 85%). Conclusions: SDF was found to be effective and well-accepted by parents and dentists for caries inactivation in a paediatric dentistry German university setting.
