RESUMO
AIM: This study aimed to compare the outcome of SCR and Pulpotomy in teeth with deep caries extending at least 75% into dentine. METHODOLOGY: This two-armed, parallel-group, randomized, superiority trial included vital mature permanent teeth with deep primary or secondary caries diagnosed radiographically as being at least 75% into the thickness of dentine, without clinical signs of symptomatic irreversible pulpitis or radiographic evidence of a periapical lesion. Carious teeth were blindly allocated to receive either SCR or Pulpotomy using computer-generated randomized patient codes concealed in opaque envelopes. All teeth were reviewed clinically and radiographically at 6 months and 1 year post-treatment. Using a significance level of p < .05, the log rank test and Cox proportional hazards regression were used to compare the outcome of SCR and Pulpotomy and to identify potential prognostic factors, respectively. RESULTS: In all, 58 teeth in the SCR group and 55 teeth in the pulpotomy group completed treatment, after excluding 6 teeth because they did not complete the allocated treatment and another due to severe periodontal disease. At one year, 57/58 (98.3%) teeth from the SCR group and 48/55 (87.3%) teeth from the Pulpotomy group were available for analysis. One tooth in the Pulpotomy group (2.1%) and eight teeth in the SCR group (14.0%) required the further intervention of root canal treatment (p < .05). There were no other significant prognostic factors for survival. Overall, 91.4% of teeth treated with either SCR or Pulpotomy survived without requiring further intervention over a period of one year. No other adverse events occurred over the review period. CONCLUSION: Within the limitations of this study, Pulpotomy fares better than SCR in preserving the remaining pulp and periapical health. As a treatment modality, Pulpotomy carries greater cost outlay to patient and takes a longer time to complete treatment than SCR. Long-term follow-up is needed to study the pulpal and restorative outcomes of Pulpotomy and SCR.

PURPOSE: To examine the relationship between parenting styles and parental attitudes towards oral health practices in children. METHODS: Parents of children aged 4-6 years presenting to four public dental clinics completed the Parenting Styles Dimensions Questionnaire (PSDQ) and a questionnaire on parental attitudes, child diet and oral hygiene practices. Child oral health was evaluated using Plaque Index (PI) and dmft-Index. RESULTS: Three hundred and eighty-nine children (mean age: 62.3 ± 9.8 months) were recruited. The median dmft was 4 (IQR = 9) and median PI was 1.5 (IQR = 0.8). An authoritative parenting style was observed in 95.1% of parents. Authoritative parents were more likely to monitor sweets/snacks intake (P = 0.004) and less inclined to offer sweets/snacks in exchange for good behaviour (P = 0.04) than permissive parents. However, actual between-meal snacking frequency did not differ between styles (P = 0.43). Permissive parents were less likely to ensure bedtime toothbrushing (P = 0.001) or brush thoroughly when busy or tired (P = 0.03) compared to authoritative parents; these attitudes were associated with higher frequencies of actual omission of bedtime toothbrushing (P = 0.006) in their children. A higher frequency of omitting bedtime toothbrushing significantly predicted a permissive parenting style (OR = 12.1, P = 0.009). Parenting styles were not associated with dmft (P = 0.72) and/or PI (P = 0.34). CONCLUSIONS: Authoritative parenting was associated with positive attitudes regarding both preventive dietary and oral hygiene practices. Actual oral hygiene practices were more ideal in children with authoritative parents, but parenting styles had no impact on actual dietary habits.

PURPOSE: MTA apical plug approach is considered the gold standard in managing immature teeth with necrotic pulp tissues but does not increase root dimensions. Regenerative Endodontic Therapy (RET) has been advocated as an alternative technique for management of these teeth. This study aimed to assess the knowledge, experience and the opinions of dentists treating paediatric patients in the European and Arabian regions on RET. METHODS: A cross-sectional, pre-piloted 23-item self-administered questionnaire survey was distributed electronically using the Bristol Online Survey tool through the mailing list of the European Academy of Paediatric Dentistry, the Arabian Academy of Paediatric Dentistry's and the Egyptian Society of Paediatric Dentistry. RESULTS: 308 respondents completed the survey. Approximately half practised RET (N = 158; 51.3%), which was most frequently used to manage non-vital traumatized teeth. Majority of RET practitioners worked in university or dental institute practices. Protocol differences with deviation from the current published RET guidelines were observed. Half of the respondents reported discolouration as an undesirable outcome. Lack of training, materials, evidence and suitable cases were reasons for not using RET. CONCLUSIONS: Although RET is being practised by European and Arabian paediatric dentists, different protocols are being used with clear deviations from the current evidence-based guidelines.

PURPOSE: Parents find it challenging to follow recommendations to brush young children after feeds at night despite the increase caries risk. This study compared three clinical recommendations (dilution, rinsing and wiping) on plaque pH after formula consumption. METHODS: Eighteen subjects were recruited. The five interventions with 2-week washout between visits included: Rinse with undiluted formula for 30 s (UF); rinse with 50% diluted formula for 30 s (DF); rinse with undiluted formula for 30 s, followed by rinsing with water for 1 minute (UF/R); rinse with undiluted formula for 30 s, followed by wiping (UF/W); rinse with 10% sucrose for 30 s as control (C). Plaque samples were collected at baseline, 2, 5, 10, 20 and 30 min after the intervention and pH measured using the plaque sampling method. RESULTS: UF/R resulted in significantly smaller pH drops at 5, 10 and 20 min compared to UF. It also resulted in higher minimum pH (UF/R: 6.34 ± 0.36 Vs UF: 6.06 ± 0.40, p = 0.02), smaller maximum pH drop (UF/R: 0.63 ± 0.35 Vs UF: 0.90 ± 0.49, p = 0.03), smaller sum of change of hydrogen ion concentration (UF/R: 9.22 × 10-7 ± 7.8 × 10-7 Vs UF: 2.30 × 10-6 ± 2.6 × 10-6, p = 0.04), and smaller area under the curve (UF/R: 7.70 ± 5.44 Vs UF: 13.44 ± 9.44, p = 0.02). DF and UF/W did not result in any significant pH change compared to UF. CONCLUSIONS: Of the three clinical recommendations, only rinsing with water for 1 min after undiluted formula reduced plaque acidogenicity. Teeth wiping with a moist cloth and 50% dilution of infant formula did not have an effect on plaque acidity.
