Dento-skeletal Sequel of Hyrax in Nonsyndromic Cleft Lip and Palate: A Systematic Review and Meta-analysis.

Aim: To critically evaluate and review the dento-skeletal outcomes of hyrax with or without nonsurgical protraction therapy in nonsyndromic cleft lip and palate (CLP) patients. Materials and methods: Electronic databases were searched from PubMed, Cochrane, Scopus, SciELO, Lilacs, and Google Scholar from January 2005 to April 2022 to identify studies reporting on the dento-skeletal effect of hyrax with or without nonsurgical protraction therapy among children aged 7-15 years with CLP before the secondary alveolar bone grafting (SABG) procedure. Abstracts and subsequently eligible full-text articles were screened. The risk of bias in the included randomized and nonrandomized studies was assessed using Cochrane collaboration's risk of bias tool. The random-effects meta-analyses of the mean difference were carried out. Results: A total of 423 studies were identified. After a thorough screening, 19 studies met the inclusion criteria. Of these 19 studies, 13 studies were conducted with only hyrax appliances, six studies had hyrax with nonsurgical protraction therapy. Conclusion: Hyrax had increased intermolar width, anterior nasal cavity width, and posterior maxillary width compared to inverted mini hyrax with p-values = 0.027, 0.004, and 0.03, respectively. Inverted mini hyrax had more canine inclination on noncleft than hyrax. Hyrax and fan-type expanders had an equivalent effect on the dento-skeletal structures indicating that hyrax can be used as an alternative to fan-type expanders. Hyrax with protraction therapy had a remarkable change in ANB angle compared to noncleft patients. How to cite this article: Deepika U, Ray P, Nayak A, et al.

Clinical evaluation of bioactive resin-modified glass ionomer and giomer in restoring primary molars: A randomized, parallel-group, and split-mouth controlled clinical study.

Aim: This study aims to evaluate and compare the clinical performance of two restorative materials - bioactive resin-modified glass ionomer (ACTIVA BioACTIVE restorative) and giomer hybrid composite (Beautifil Flow Plus) in restoring class I carious primary molars. Materials and Methods: The split-mouth randomized controlled study was conducted on 100 primary molars from 50 children (28 - males, 22 - females) from 50 children in age range of 5-9 years (Mean-7.29±1.34) with at least two occlusal carious lesions on either maxillary or mandibular primary molars. Each child had both the control and the experimental teeth restored with respective restorative materials, Group I (Control, n = 50) → Giomer, Group II (Experimental, n = 50) → Bioactive resin-modified glass ionomer. The restorations were evaluated by two independent investigators using modified United State Public Health Service criteria at immediate postoperative, 6 months, and 12 months. The Chi-square test was used for the statistical analysis after collecting the data. Results: At the 12-month follow-up, 33 children (66 teeth) reported with an attrition rate of 33%. The color match between the groups was not statistically significant at all intervals. The marginal discoloration, marginal integrity, anatomic form, and retention had no significant difference at 6 months. But at 12 months, there was a statistically significant difference between the groups with p value of 0.04,<0.001,<0.02 and <0.001 respectively. respectively. At 12 months, there was no postoperative sensitivity in both groups. Conclusion: Bioactive resin-modified glass ionomer with enhanced properties can be used as an effective restorative material, especially in children with excessive salivation.
