Objectives: To investigate treatment outcomes of different restorative techniques undertaken by dental therapists for primary molar carious lesions in a sample of children in New Zealand primary care. Methods: This was a randomized controlled trial with children aged 3 to 8 y in New Zealand’s Whanganui region. Children meeting inclusion criteria were randomly allocated to treatment with either the Hall technique (HT), in which a stainless-steel crown (SSC) is placed without any carious tissue removal or tooth preparation, or a non-Hall conventional restorative approach (NHT), including tooth preparation with selective carious tissue removal; this included SSC, amalgam, composite, or glass ionomer cement (GIC) restorations. Restorative outcomes after 12 and 24 mo were categorized as success, minor failure, or major failure. Results: Of the 295 eligible children, 149 and 146 were allocated to the HT and NHT groups, respectively, with a total of 570 carious primary molars treated by 13 dental therapists. The participant follow-up rates at 12 and 24 mo were 95% and 91%. SSCs were the most commonly used restoration in the NHT group (60%), followed by GIC (28%). SSCs were the most successful restorations regardless of whether they were placed with the HT or NHT, with success rates of 89% and 92% at 12 mo and 85% and 86% at 24 mo. In the NHT group, the treatment material was a predictor of minor failure at 12 and 24 mo, with significantly more failures with GICs. Conclusions: SSCs placed by dental therapists are a highly successful restoration for the primary dentition, regardless of whether they are placed with the HT or conventionally. The high failure rate of glass ionomer restorations means that they cannot be recommended for widespread use in New Zealand primary care (Australian New Zealand Clinical Trials Registry, ACTRN12614000844640). Knowledge Transfer Statement: The findings of this study can be used by policy makers and clinicians when deciding on which materials and which approach to use to maximize success and to minimize retreatment rates when providing restorative treatment for carious primary molars in children’s primary oral health care. Results also suggest that undertaking research in the primary care setting may enhance translation of new knowledge and techniques into clinicians’ hands.

Abstract Background: Dental caries is a multifactorial disease which starts with microbiological shift within the complex biofilm and is affected by salivary flow and its composition, exposure to fluoride, consumption of dietary sugars, and by preventive behaviors (cleaning teeth). Topical application of fluoride varnish on the tooth surface prevent the dissolution rates of tooth materials and increase the re-precipitation of lost minerals. The objective of the present study was to assess the effectiveness of fluoride varnish application in primary dentition among preschool children at high risk of dental caries. Methods: A randomized controlled trial was conducted with two parallel group, comprising 3-5 year old children, 100 in each group (Fluoride varnish/FV or Placebo varnish/PV). Oral examination of children was performed using mouth mirror and WHO probe. Dental caries was recorded at baseline, three and six months using Caries Assessment and Treatment Instrument (CAST) scoring system. Analysis was done using chi-square test for categorical data, Mann-Whitney U test, independent t test and Wilcoxon Signed Ranks test for quantitative data. The level of significance was set at p<0.05. Results: Overall, dental caries progression from baseline to 3 month and 6 month was more in PV group children than FV (38.98% and 31.3% respectively). At the end of the study, the overall caries incidence was 28.24%. The proportion of children with new caries lesions was more in PV group than that in the FV group at every three months interval. The difference between the groups were statistically significant (p<0.05). FV treatment once in six months had better treatment effect with preventive fraction of 62.1% in comparison to three months (59.0%). Conclusion: Dental caries can be prevented effectively by use of 5% sodium fluoride varnish. It is efficacious when applied twice a year in children at high risk of dental caries.
