RÉSUMÉ
PURPOSE: The aim of this study was to compare dental-treatment outcomes, oral-hygiene improvement, and patient co-operation during follow-up visits between children treated under general anaesthesia (GA) and non-pharmacological behaviour management (NP). METHODS: This retrospective study reviewed the dental chart records of healthy patients less than 71-month-old with severe early childhood caries (S-ECC) from 2008 to 2020 with at least a 6-month follow-up. The demographical data, dental-treatment outcomes, oral-hygiene status, and patient behaviour at the follow-up visits were analysed by the Mann-Whitney U test, Pearson's Chi-square, Fisher's exact test, Friedman test, and Wilcoxon test with a significance level of 0.05. RESULTS: This study included 210 GA cases and 210 age-matched control NP cases. The GA group had a significantly higher caries experience, lower patient co-operation, poorer oral hygiene, and higher number of complex dental treatment than the NP group at baseline (p < 0.001). The number of children who had incomplete dental treatment under non-pharmacological behaviour management was higher than the GA group. After treatment, the number of new carious teeth in the NP group was significantly higher than in the GA group only at the 6-month follow-up. However, there was no significant difference in treatment failure, oral-hygiene improvement, and patient behaviour between groups. CONCLUSION: Although patients in the GA group had higher dental and behaviour problems than the NP group, the overall dental-treatment outcomes, including oral hygiene and behaviour improvement, were not significantly different between groups Therefore, regular follow-up and preventive treatment in the maintenance phase are essential for children with severe early-childhood caries.

AIM: This was to compare the effectiveness of different preparations and delivery techniques of calcium hydroxide paste as an intracanal medicament in primary molar root canals. METHODS: Extracted lower primary second molars roots (72) were randomly assigned to the four experimental groups. After complete root canal preparation with TF rotary nickel titanium up to .06/30 file, a mix of calcium hydroxide/ distilled water was delivered by lentulo spiral (group 1) or a syringe (group 2). UltraCal(®) XS was placed by lentulo spiral (group 3) and a syringe (group 4). Digital radiographs were taken in both buccal and proximal directions before and after calcium hydroxide placement to evaluate the quality of filling. The mean percentages of filled calcium hydroxide area by subtracted digital radiograph, and the quality assessments between four experimental groups, were compared by using Two-way ANOVA and Fisher's exact test respectively. A p value of less than 0.05 was considered statistical significance. RESULTS: There was no statistically significant difference in the mean percentages of the filled calcium hydroxide area among different preparations and delivery techniques (p ≥ 0.05). The syringe technique had statistically significant fewer of air inclusions than when using the lentulo spiral with the mix of calcium hydroxide group (p < 0.05). The completeness of obturation and the quality of filling at apical part were not different among groups (p ≥ 0.05). CONCLUSION: Syringe technique was a simpler handling method that presented similar filling quality but fewer porosities than lentulo spiral technique in primary molar root canals.
