Aims:The aim of this study was to assess oral health-related quality of life (OHRQoL) using short form (SF) of child oral health impact profile (COHIP) in children aged 11–15 years who sought orthodontic treatment. A comparison was done between these children and age-matched peers who never had or sought orthodontic treatment.Methodology:This cross-sectional study included 227 children aged 11–15 years. A total of 110 participants had sought orthodontic treatment at KSR Institute of Dental Science and Research (orthodontic group) and 117 participants from a nearby school who had never undergone or sought orthodontic treatment (comparison group). OHRQoL was assessed with the SF of the COHIP, and malocclusion severity was assessed with the index of orthodontic treatment needs. Data presentation and statistical analysis were performed with the Statistical Package for the Social Sciences Software (Version 19, SPSS, Chicago, IL, USA). The Chi-square test and Fischer exact tests were used to analyze the qualitative data.Results:Children with little to borderline treatment needs have a better quality of life when compared to children with definitive treatment needs (P = 0.049). No statistically significant difference in COHIP-SF scores was found between boys and girls (P > 1.000). In the orthodontic group, children with little to borderline treatment needs were 4.8 times (P = 0.037) more likely to report better OHRQoL when compared to children with definitive treatment needs.Conclusion:Children who sought orthodontic treatment had lower quality of life scores than those who never had or never sought treatment.
Background: Successful obturation in the primary teeth demands complete dryness of the root canal system.Aim: The purpose of this study was to determine the effect of 95% ethanol as the final irrigant before root canal obturation in primary teeth.Materials and methods: A total of 20 extracted primary mandibular canines were biomechanically prepared and pre-obturated volume of each tooth was assessed using spiral computed tomography (CT). The specimens were divided into two groups (n = 10): group 1, Metapex group; group 2, zinc oxide eugenol group. Each group was further divided randomly into two subgroups (n = 5): subgroup 1, canals were dried with 95% ethanol; subgroup 2, canals were blot dried with paper points with the last one appearing dry. All canals were obturated and the postobturated volume of each tooth was measured. The percentage of obturated volume (POV) was calculated using the formula: (postobturated volume/preobturated volume) × 100. The POV between the groups was statistically analyzed using Mann-Whitney test and Wilcoxon Signed rank test appropriately.Results: Root canals that were dried with ethanol showed better obturation than using paper points alone and the difference was statistically significant in both group 1 (p < 0.001) and group 2 (p < 0.002).Conclusion: Drying of the root canal system with 95% ethanol can result in better obturation in the primary teeth.How to cite this article: Thiruvenkadam G, Asokan S, John B, Geetha Priya PR.

The primary outcome was incidence of intradialytic hypertension (IDH) during standard and cooler isothermic dialysate temperatures. Two pair of haemodialysis sessions were done at 37°C (SHD) and at isothermic temperature (IHD). All the four dialysis were done on the same time of the day to negate the changes due to circadian variation in body temperature. Axillary and tympanic temperatures were measured before start of the dialysis and dialysis temperature was adjusted as per axillary temperature. Sixty patients were enrolled and completed the study. The mean delivered dialysate temperature in the intervention group was 36.5 ± 0.2 achieving a 0.5 ± 0.2°C between-group separation. The incidence of IDH and intradialytic hypotension while on SHD and IHD were 79/120 (66%) vs 44/120 (37%), odds ratio (OR) 3.3, 95% confidence interval (CI) (1.96–5.65) and 45/120 (38%) vs 14/120 (12%), OR 4.5, 95% CI (2.3–8.7), respectively. The 4 h time averaged mean systolic blood pressure (SBP) at IHD and SHD were 154 ± 1.7 and 157.2 ± 1.1 mmHg, respectively, the mean difference in SBP being −3.4 mmHg to −3.1 mmHg, 95% CI, P < 0.001. The standard deviation, a measure of BP variability was lower at IHD than at SHD (P < 0.001). In a subgroup analysis during IHD there was a significant reduction of both SBP and diastolic BP during the entire duration of dialysis in 35 out of 60 patients (systolic 4 h mean 154.96 ± 2.22 vs 164.32 ± 1.99 mmHg), (diastolic 4 h mean 79.24 ± 0.82 vs 82.54 ± 0.68 mmHg) – (rANOVA for systolic and diastolic <0.001). This phenomenon of cooler dialysis causing reduction of BP was reproduced in the same group of patients when the IHD was repeated another time (systolic 4 h mean 157.95 ± 1.88 vs 160.65 ± 1.47), (diastolic 4 h mean 79.27 ± 0.74 vs 82.03 ± 1.07) rANOVA for systolic and diastolic <0.001. The incidence of IDH can be reduced significantly by reducing the dialysate temperature to patients' body temperature. Hypertension during dialysis is related to heat gain during dialysis.
Among the psychosocial outcomes assessed, inferiority and friendliness had significant association with oral health of the children and hence, can be used as a proxy measures oral health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
