Oral health–related quality of life (OHRQOL) of preschool children’s anterior teeth restored with zirconia crowns versus resin-bonded composite strip crowns: a 12-month prospective clinical trial

Abstract

Objectives To compare oral health–related quality of Life (OHRQOL) of preschool children’s anterior teeth restored with prefabricated zirconia crowns (ZC) versus resin-bonded composite strip crown (RCSC). Materials and methods A prospective clinical trial included 136 children with early childhood caries aged 36–71 months who were assigned into prefabricated ZC and RCSC groups. A total of 344 teeth were restored either with 170 ZCs (49.4%) and 174 RCSCs (50.6%). Wilson and Cleary’s conceptual model was to associate the study predictors to the OHRQOL. Early Childhood Oral Health Impact Scale (ECOHIS) was used to assess the OHRQOL at 6 and 12 months. Mann–Whitney U test was used in comparing OHRQOL mean scores in the two groups and Wilcoxon signed-rank test with the effect size (r) to measure the intragroup OHRQOL change. A Poisson regression model was used to study potential risk factors associated with the overall OHRQOL. Results After 12 months, the USPHS parameters of the ZC were significantly superior compared to the RCSC. Overall ECOHIS mean scores in the ZC group were significantly lower than that of the RCSC group at T1 and T2 (p < 0.001). Remarkable enhancement of the OHRQOL at the follow-ups with a large effect size (r < 0.8) was observed. Restoration type, retention, baseline OHRQOL, and color had a significant impact on the overall OHRQOL at 12 months. Conclusions Preschool children OHRQOL treated with ZC were significantly better than those who received RCSC. Clinical relevance One of the optimum treatment standards in pediatric dentistry is the esthetic demand which has significance on the child’s OHRQOL and subsequently child’s general health quality of life. It is beneficial to the dentist to identify the influence of esthetic restorations on the OHRQOL of preschool children which aids in future decision-making. The longitudinal nature of the study enables the dentist to identify the changes of children’s OHRQOL.

The effects of safinamide on dysphagia in Parkinson’s disease

“…For another exploratory outcome, the differences of motor function scores and those of VFSS were analyzed by Spearman correlation coefficient, without p-value adjustment; hence statistically significant levels were not set in this study. The non-parametric effect size (r) was calculated by dividing the absolute standardized statistic (z) of the Wilcoxon signed-rank test by the square root of the pair number (z/√N) [ 24 ]. Interpreting the “r” values was as follows: small effect size (r < 0.3), moderate effect size (r = 0.3–0.8), and large effect size (r > 0.8) [ 24 ].…”

Because nonparametric statistics were applied in this study, the Spearman correlation coefficient was used to assess the intra- and inter-rater reliability of the three evaluators for total scores, scores during the oral and pharyngeal phases, and DOSS scores [ 25 ].…”

Microleakage of luting cements in CAD/CAM pediatric zirconia crowns: An in vitro study

“…PZCs showed signi cantly less plaque accumulation and gingival in ammation when compared to conventional stainless-steel crowns [4,7,8]. Moreover, the oral health-related quality of life of preschool children that were restored with PZCs was signi cantly better than that of those who received resinbonded composite strip crowns [9,10]. However, concerns about the retention of PZCs have arisen due to their limitations.…”

Infraocclusion level and root resorption of the primary molar in second premolar agenesis: A retrospective cross-sectional study in the Portuguese population

“…76 The OHRQoL of preschool children treated with zirconia crowns was described as significantly better as compared to those who received resin-bonded composite strip crowns. An adapted and validated Early Childhood Oral Health Impact Scale (ECOHIS) questionnaire could be an excellent tool to distinguish children without agenesis from those with a moderate to high percentage of missing teeth, like it has been made for caries experience, 77 or to determine the impact of dental treatment on OHRQoL. 78 There is still no evidence of a longterm survival of mandibular 2pm, and to accurately answer the typical questions from the patient: "For how long can my primary tooth survive if we decide to leave it in situ?"…”
