RESUMEN
STUDY DESIGN: A randomised parallel controlled clinical trial was conducted between 2013 and 2015 at the University of Sao Paulo, Brazil, to assess the impact of pulpectomy or extraction on the oral health-related quality of life (OHRQoL) of children with pulp necrosis in primary molars. STUDY SELECTION: Children between the ages of 3 and 5 who were in good health but had extensive caries in at least one primary molar with signs of pulpal necrosis (also as seen radiographically, caries reaching the pulp with no signs of internal or external resorption) were considered for inclusion. Additionally, teeth with sufficient structure for rubber dam placement were also included. Children with any systemic, neurological, or other conditions that negatively impacted their growth were excluded. CLINICAL PROCEDURES AND SUCCESS CRITERIA: After computer-generated randomisation, 100 children were assigned randomly into two groups: 50 in the pulpectomy group and 50 in the dental extraction group. A paediatric dentist performed all procedures under local anaesthesia without sedation or general anaesthesia, and a rubber dam was used for pulpectomy with composite restoration in a single session. The OHRQoL scores were evaluated at baseline, 4, 8, and 12 months using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) via face-to-face interviews with parents conducted by a researcher trained in a single-blinded fashion. Additionally, the child's self-reported dental anxiety was measured using the Facial Image Scale (FIS), and dental pain was assessed using the Wong-Baker Faces Pain Scale (WBFPS) immediately after the treatment as secondary outcomes. RESULTS: The mean difference (SD) in the total B-ECOHIS score between baseline and after 12 months was 12.66 (6.79) for the pulpectomy group and 10.94 (9.28) for the extraction group, with effect sizes of 3.2 (95% CI: 2.42-4.20) and 1.4 (95% CI: 0.84-2.11), respectively. While both treatments significantly improved the children's OHRQoL after 12 months, the pulpectomy group showed greater long-term improvement compared to the extraction group, with mean differences (SD) of 4.86 (6.13) and effect sizes of 0.8 (0.46-1.13; p < 0.001). Moreover, children in the extraction group showed higher levels of anxiety compared with those in the pulpectomy group at 12-month follow-up (OR = 2.52; 95% CI = 1.30-4.89), and they reported 93% more odds of 'dental pain with high level' immediately after treatment than those in the pulpectomy group (OR = 1.93; 95% CI = 0.83-4.49). CONCLUSION: Children treated with pulpectomy in their necrotic primary molars were found to have better OHRQoL than those who had their primary molars extracted.

OBJECTIVES: To understand the environmental impact of providing a nationwide supervised toothbrushing programme (Childsmile) for 5-year-old children in Scotland. METHODS: A life cycle assessment was conducted to assess the annual environmental effects of the supervised toothbrushing programme in early years childcare, as well as each dental procedure (dental restoration under local anaesthesia (LA), single tooth extraction under LA, and multiple teeth extraction under general anaesthesia) spanning from 2001/02 to 2009/10. The expected savings in annual carbon dioxide equivalent (CO2e) emissions for all combined dental treatments in subsequent years were calculated compared to those in 2001/02. RESULTS: An overall decrease in CO2e emissions was evident in the Childsmile programme and across all dental procedures. The estimated reduction in emissions across all procedures varied from 102.5 tonnes in 2002/03 to 461.1 tonnes in 2009/10 when compared to 2001/02. Within three years, the expected emissions savings from all combined dental procedures surpassed the emissions generated by implementing the Childsmile programme. CONCLUSIONS: Over time, there was a significant reduction in annual CO2e emissions for all combined dental treatments in children. In the eighth year of the Childsmile, emissions savings were more than 4.5 times greater than the emissions generated during its implementation. CLINICAL SIGNIFICANCE: The study highlights the importance of educating public by individual dentists about the environmental impact of caries prevention programmes and paediatric dental treatments as this may influence patient choice. It also encourages commissioners of community dental programmes to support the implementation of supervised toothbrushing programmes in early years childcare.
