Clinical Performance of Newly Developed Android Mobile Digital Application on Tooth Shade Reproduction: A Multicenter Randomized Controlled Clinical Trial.

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.

The Systematic Review and Meta-analysis of Oral Sensory Challenges in Children and Adolescents with Autism Spectrum Disorder.

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.

The rehabilitation of posterior atrophic maxilla by using the graftless option of short implant versus conventional long implant with sinus graft: A systematic review and meta-analysis of randomized controlled clinical trial.

Aim: The purpose of systematic review and meta-analysis was to compare the efficacy of short implant versus conventional long implant with sinus graft in patients rehabilitated for posterior atrophic maxilla. Setting and Design: Systematic review and meta analysis. Materials and Methods: Electronic searches were conducted in Pub Med, Embase, and Medline with supplemented by manual search up to December 2019. The randomized controlled trial (RCTs) comparing short implant (<8.5 mm) and long implant (>8.5 mm) with sinus graft were included. (Prospero CRD42020186972). Statistical Analysis Used: Random-effect model, fixed-effect model, A funnel plot and the Egger's test. Results: Twenty-two Randomized controlled trials (RCTs) were assessed with 667 patients and 1595 implants (short implant:767, Long implant:835). No significant difference of implant survival rate was recorded for short and long implant (at patient level: RR: 1.01, 95% CI = 0.52-2.0, P = 0.87, I2 = 0%, at implant level RR = 1.09, 95% CI = 0.6-2.0, P = 0.7, I2 = 0%). Similarly marginal bone resorption was reported no difference for short and long implant (MD = 0.16. 95% CI: -0.23 = -0.08, P = 0.00, I2 = 74.83%). Biological complications were marginally higher for long implant (RR = 0.48, 95% CI = 0.23-0.8, P = 0.13, I2 = 29.11%). and prosthetic complications were marginally higher for short implants (RR=1.56, 95% CI=0.85-3.15, P = 0.43, I2 = 0%). Conclusion: There was no significance difference in implant survival rate and marginal bone resorption recorded for both the short implant and long implant with sinus graft, in the patients rehabilitated with posterior atrophic maxilla. Hence, short implant is a suitable alternative to long implant with sinus graft, for the rehabilitation posterior atrophic maxilla.

A systematic review and meta-analysis of the attachments used in implant-supported overdentures.

AIM: To evaluate the survival rate, tissue response, and patient satisfaction of different attachments used in implant overdenture. SETTINGS AND DESIGN: Systematic Review and Meta-analysis. MATERIALS AND METHODS: Electronic search of peer-review articles published between 2001 and 2019 assessing the attachments used for implant-supported overdentures was done according to PRISMA Guidelies. The review evaluated sixteen articles related to survival of the attachments, the reaction of the soft and hard tissues along with repair and maintenance of the attachments, and overall performance of the overdenture attachments. STATISTICAL ANALYSIS USED: There is statistically significant heterogeneity (Q =374.7403, df = 15, and P < 0.0001). The statistics of fixed-effect model reported an MD of - 0.0880 (95% CI = -0.1536; 0.0225). RESULT: The review evaluated the 16 articles that met with the inclusion and search criteria. The studies were the combination of bar and ball attachments and their subtypes, magnetic and bar attachments, and locator in combination with other attachments. The meta-analysis of combined 16 studies reported acceptable heterogeneity among 16 studies (I 2 = 96%) and reported to be statistically significant (P < 0.01). CONCLUSION: The survival rate of attachments was in the range of 95.8%-97.5% for bar, 96.2%-100% for ball, 90%-92% for magnet and locator attachments were in the range of 97% after a mean follow-up period of 3 years. The bar attachments reported moderate tissue reaction in the form of mucosal changes, gingival inflammation, and bone resorption. The locator attachments require higher maintenance and repair. The magnetic attachments produce higher bone resorption and readily displace under functional force. Patient satisfaction and compliance was higher for ball, locator, and bar attachments as well as low for magnetic attachment. Thus, the ball and locator attachments excellently perform in terms of survival rate, tissue response, and patient satisfaction.

Tooth shade analysis and selection in prosthodontics: A systematic review and meta-analysis.

AIM: To evaluate the methods of the dental shade selection and provide a summary of different factors affecting the shade selection. DESIGN AND SETTING: The systematic review and meta-analysis. MATERIALS AND METHODS: The electronic search of the peer-review articles between 2002 and 2018 was carried out the by using the PRISMA guidelines. A total twenty-one studies related to the visual shade methods, instrumental shade methods, and the factors affecting the shade selections was evaluated. The search strategy was based on the PICOS framework. STATISTICAL ANALYSIS: There was statistically significant heterogeneity (Q = 1038.1518, df = 20, and P < 0.0001). The statistics of fixed-effect model reported an MD of - 0.0970 (95% CI = -0.1391, -0.0549). The random-effect model reported an MD of - 0.0862 (95% CI = -0.5866, 0.4142). RESULT: The review evaluated the 21 studies of tooth colour science that met with the inclusion criteria and search criteria. The meta-analysis of the 21 combined studies reported acceptable homogeneity (i2 = 98%) which indicates a statistically significant difference between the treatment and control groups. CONCLUSION: The VES spectrophotometer reported the highest accuracy, reliability, and repeatability in shade selection followed by photo colorimetric method. The Vita 3D master shows more consistent results in repetitive shade selection. Knowledge and training of the shade selection protocol are necessary for proper shade matching.
