Objective: To determine the effectiveness of preventive interventions in children who have undergone caries-related dental extractions., Methods: Rapid review across five databases (CENTRAL, Ovid Medline, Embase, Web of Science and Scopus). Quality was assessed using the Risk of Bias 2 tool., Results: Five studies were included, all randomised controlled trials involving pre-and/or post-extractions activity. Three studies involved oral health education (computer game, motivational interviewing, visual aids), one delivered clinical prevention (fissure sealants), and one an enhanced prevention programme combining additional health education and a clinical intervention (fluoride varnish). Retention was mixed (55%-80% in the intervention groups). Of the three studies measuring caries, all reported less caries development in the test group. However, only a study involving a dental nurse-delivered structured conversation, informed by motivational interviewing, showed an improvement in oral health. Two studies reporting on plaque and gingival bleeding had conflicting results. A study reporting on subsequent dental attendance did not demonstrate a clear improvement., Conclusion: Few published studies have explored prevention-based interventions in high caries-risk children requiring dental extractions. Whilst evidence of clinical benefit of preventive interventions in this population is limited, the potential use of contemporary behaviour change techniques appears promising. There is an urgent need for more high-quality longer-term trials using contemporary methodologies., (Copyright© 2024 Dennis Barber Ltd.)

The purpose of this study was to determine the efficacy of a dental nurse-delivered intervention-the Dental RECUR Brief Negotiated Interview for Oral Health (DR-BNI)-in reducing the recurrence of dental caries in children who have a primary tooth extracted. It was based on a 2-arm multicenter randomized controlled trial with blinded outcome assessment. Participants were 5- to 7-y-old children ( n = 241) scheduled to have primary teeth extracted in 12 UK centers. Test intervention parents ( n = 119) received DR-BNI led by trained dental nurses. DR-BNI is a 30-min structured conversation informed by motivational interviewing with a forward focus to prevent future caries. Preventive goals are agreed, and a review appointment is made with child's general dental practitioner, who is advised to treat the child as being at high caries risk. The control intervention ( n = 122) was a parent-nurse conversation about child's future tooth eruption, with advice given to visit a general dental practitioner as usual. At baseline, the DR-BNI group's mean dmft was 6.8, and the control group's was 6.3. A median of 5 teeth were extracted, mainly under general anesthesia. Final dental assessments were conducted by a single examiner visiting 189 schools 2 y after intervention; 193 (80%) of 241 children were examined. In the control group, 62% developed new caries in teeth that were caries-free or unerupted at baseline, as compared with 44% in the test group, a significant reduction ( P = 0.021). The odds of new caries experience occurring were reduced by 51% in the DR-BNI group as compared with control. There was a 29% decrease in the relative risk of new caries experience in the DR-BNI group as compared with control. This single low-cost, low-intensity intervention was successful in significantly reducing the risk of recurrence of dental caries in children. This trial has implications for changing pediatric dental practice internationally. Training in and implementation of a motivational interviewing-informed brief intervention provides opportunities for dental nurses to facilitate behavior change improving the oral health of children at high caries risk (ISRCTN 24958829).
