Impression making is an important step in fabricating complete dentures. A survey to know the materials used and techniques practiced while recording complete denture impressions was conducted. It is disheartening to know that 33 % practitioners still use base plate custom trays to record final impressions. 8 % still use alginate for making final impressions. An acceptable technique for recording CD impressions is suggested.

Aim: This study aimed to determine the clinical effectiveness of android mobile digital application shade matching on tooth shade reproduction. Setting and Design: This was a double-blind randomized controlled clinical trial (REF/2021/03/042258). Materials and Methods: Thirty participants were selected from the two dental centers. The participant who required full-coverage restorations in one of the central incisors with adjacent central incisor untouched was the main inclusion criteria. Three metal–ceramic or all-ceramic crowns were fabricated with reference shades from Vita Three-Dimensional (3D) Master shade guide, Vita Easyshade spectrophotometer, and mobile application for each participant. ΔE values between reference maxillary central incisor and metal–ceramic and all-ceramic crowns were measured for each participant. In addition, two operators and participants observed the clinical agreement between for each crown on a visual analog scale. Statistical Analysis Used: ANOVA statistics and Turkey’s post hoc test were used for ΔE value. Kappa statistics was used for clinical agreement. Results: Mean ΔE value of fabricated metal–ceramic and all-ceramic crowns and reference maxillary central incisor of Vita 3D Master shade guide was significantly higher than Vita Easyshade spectrophotometer and mobile digital application ( P = 0.004). However, ΔE values of Vita Easyshade and mobile digital application were contiguous. However, ΔE value of Vita 3D Master was lower than clinically acceptable value of intraoral color difference. Kappa value figured moderate agreement for Vita Easyshade and mobile digital application and slight to no agreement for Vita 3D Master. Conclusion: Within the limitations of the study, the Android mobile digital application can turn up as a reliable method for shade selection.

A BSTRACT Objectives: The purpose of the systematic review was to provide a summary and evaluation of oral sensory challenges in children and adolescents with autism spectrum disorder (ASD). Materials and Methods: The review evaluated 19 studies that met the inclusion and search criteria. The review is registered in Prospero Database (CRD42020179852). The 14 studies (8 case–control, 4 cohort, 1 observational, and 1 randomized clinical trial) were related to speech disorders and five studies (case–control studies) were associated with feeding and eating behavior in ASD. The meta-analysis of speech and feeding behavior was analyzed by using risk ratios (RRs) and standardized mean difference (SMD), with 95% confidence interval (CI). Results: The meta-analysis found a statistically significant difference of speech disorder between children and adolescents of ASD when compared with typically developed or other neurotypical children of similar age [0.4891 (95% CI = −2.4580; 1.4799), fixed effect; −0.1726 (95% CI = −14.2925; 7.5697), random effect]. Feeding and eating behavior reported a statistically significant difference between ASD children and adolescents with similar age group of typically developed controls [0.0433 (95% CI = −0.3531; 0.4398), fixed-effect; 0.3711 (95% CI = −3.0751; 3.8172), random effect]. Conclusion: The speech errors and feeding behavior were more consistent in ASD than in typically developed controls. The oral sensory challenges such as speech disorder and feeding behavior were more prevalent in ASD children and adolescents than in typically developed children and adolescents of the same age group. There was a significant lack in oral sensory-motor synchronization, incomplete motor planning, and poor oral neuromuscular coordination.

To determine the clinical performance of zirconia abutment (ZA) by comparing with a titanium abutment (TA) and sub-mucosal-modified zirconia abutment. A systematic search was conducted to retrieve eligible randomised controlled trials (RCTs) from Medline, Cochrane Library, SCOPUS, Embase, Web of Science, and Google Scholar. A search was further divided in two parts. Part I comprises eligible RCTs between zirconia abutment and titanium abutment, and part II included RCTs of zirconia abutment with sub-mucosal modified, pink-veneered glass ceramic versus non-veneered zirconia abutment. Esthetic, biological, and abutment survival was a primary outcome, and technical complications were included as an additional outcome. Fifteen eligible RCTs (Part I: N = 9 and Part II: N = 6) were evaluated, and a total of 362 abutments in 364 subjects were analysed for outcome variables. A sub-group meta-analysis reported no significant difference for Esthetic outcome. However, the overall mean (p =0.03) was higher for zirconia group in those of thin gingival phenotype. Spectrophotometric evaluation of peri-implant mucosal Esthetic does not show any significant difference. Similarly, pink-veneered versus non-veneered group reported no significant difference for thin (<2 mm) and thick (>2 mm) mucosal attachment. Biological outcome does not show any significant difference for comparable groups in both parts. There is marginally lower abutment survival for internally connected zirconia abutment (ZA: 95.4% TA: 100%). Zirconia abutment exhibited excellent Esthetic compared to titanium abutment in those of thin gingival phenotype. Sub-mucosa veneering of zirconia abutment with pink glass ceramic does not show any favourable Esthetic outcome compared to the non-veneered surface.
