Artificial intelligence (AI) is a contemporary, information-driven innovative technology. Prosthetic dentistry, also known as prosthodontics, is the restoration and reconstruction of missing teeth utilizing implants for permanent and removable prostheses. It enhances healthy soft and hard tissues, promoting oral health. This study examined the use of artificial intelligence in prosthodontics to diagnose abnormalities and create patient-specific prostheses. Two researchers searched Google Scholar, Scopus, PubMed/MEDLINE, EBSCO host, Science Direct, and Web of Science (MEDLINE, WOS, and KJD). Articles on AI in English were reviewed. We also collected the following broad article aspects: research and control groups, assessment methodology, outcomes, and quality rankings. This methodological study examined AI use in prosthodontics using the latest scientific findings. The findings were statistically evaluated using ANOVA. Titles and abstracts revealed 172 AI-related dentistry studies, which were analyzed in this research. Thirty-eight papers were eliminated. According to the evaluation, AI was found to have significantly increased in prosthodontics. Despite the vast number of studies documenting AI applications, the description of the data illustrated the latest breakthroughs in AI in prosthodontics, highlighting its use in automatically produced diagnostics, predicting analytics, and classification or verification tools.

Background: The purpose of this study evaluates and compares the effect of surface roughness (Ra) and color stability on computer-aided design/computer-aided manufacturing (CAD/CAM) hybrid resin (Vita Enamic), feldspathic (Vitablocs® Mark II), and lithium disilicate Zirconia (Vita Suprinity) glazed or polished ceramics immersed in hot Arabic Qahwa and cold coffee. Methods: A total of 96 standardized samples were prepared from CAD/CAM restorative materials. Half of the samples were polished as per the manufacturer’s instructions using a porcelain polishing kit, and the other half were glazed. Samples were distributed and immersed in hot Arabian Qahwa and cold coffee followed by thermocycling. Ra measurements and color changes were conducted before and after immersion. SEM images were captured from each type of glazed or polished ceramic. One-way ANOVA paired Student’s t-test, and Bonferroni test were conducted to detect significant difference between the groups. P > 0.05 was a significant level. Results: Of all the tested samples, Ra increased without any significant difference; however, mean color changes (ΔE*) showed significant differences. An increase in Ra was noted for all the glazed and polished samples after immersion and thermocycling. However, differences were significant only in VM II. In addition, ΔE* was significant only in Vita Suprinity (VS) samples. For immersion groups, significant Ra changes were noticed in glazed samples, only in Vita Enamic (VE) with no ΔE*. In polished samples, mean Ra changes were observed in VM II and VS samples. Significant differences were also noticed in polished VE and VS subgroups of ΔE*. Conclusions: Ra affects all the tested samples, providing higher values on the polished specimens. The ΔE* caused by hot Arabic Qahwa and cold coffee on glazed or polished CAD/CAM restorative materials were clinically acceptable.

Background and objectives: Polyvinyl ether siloxane (PVES) possesses ideal characteristics for making precise and accurate dental impressions. PVES dimensional stability owes to its better polymeric properties derived from its parent materials poly ethers and polyvinyl siloxanes. As recommended use of chemical disinfecting agents is getting more popular, there is a growing concern associated with the effect of disinfectants on PVES dimensional stability. This study was aimed to understand the PVES behavior when subjected to chemical disinfectants. Materials and methodology: The data was collected from research studies retrieved from Google Scholar, Scopus, and PubMed using MeSH terms of keywords “vinyl polyether siloxane AND Disinfection” or (Vinyl polyether siloxane OR polyvinyl siloxane ether OR PVES) AND (disinfectant OR disinfection)” without any restriction to publication date. The PRISMA (Preferred Reporting Items for Systemic Review and Meta-Analysis) directions were observed during the data collection, screening of studies, and meta-analysis. The primary data were retrieved, and batch exported from databases using Harzing’s Publish or Perish software; primary analysis was performed in Microsoft Excel, while statistical analysis for effect size, two-tailed p-values, and heterogeneity among studies was performed using Meta Essentials. The effect size was calculated using Hedge’s g values at the 95% confidence level using the random-effects model. Heterogeneity among studies was measured using the Cochrane Q and I². Results and conclusion: Dental impressions made from the PVES elastomeric impression materials showed no significant changes in dimensional stability. Immersion in the chemical disinfectant for 10 min was associated with clinically irrelevant changes in the dimensions of the PVES impressions. Disinfection with sodium hypochlorite was associated with clinically significant changes in dimensions, with a two-tailed p-value of 0.049. Disinfection with 2–2.5% glutaraldehyde solution was not associated with any significant dimensional variability.

Purpose: The aim of this study was to compare the preclinical and clinical undergraduate dental students’ perceptions of their educational climate (EC). In addition it will be compared with other local and international studies. Materials and Methods: Students enrolled in their third and fourth years (preclinical phase) and students in their fifth and sixth years (clinical phase) of the Bachelor of Dental Science at the University of Jazan, Saudi Arabia, were invited to complete a WhatsApp media survey, which included demographics and the Dundee Ready Education Environment Measure (DREEM). This scale measured students’ overall perceptions of the EC in five domains: learning, teaching, academic self-perception, atmosphere, and social self-perception. Data were analyzed with Student’s t-tests and ANOVA to compare between and within groups. Results: A total of 272 participants, 140 (51.5%) preclinical and 132 (48.5%) clinical students,took part in the study. Students were generally positive about their learning climate, with overall DREEM scores of 125.19 and 126.21 (preclinical) to 124.10 (clinical) out of a possible score of 200 phases. Student’s perceptions of teaching (26.18± 3.24/72.72%) and atmosphere (28.08± 5.29/63.82%) were the highest and lowest scores, respectively, and both scores were positive. Conclusion: No differences between the preclinical and clinical phases of the curriculum point to the structure of learning, teaching, academic, social self-perception in health professional degrees. Further research should investigate the weak points in the social and atmospheric climate.

Intrabony defects can be treated by various approaches. Use of GTR along with bone grafts is said to enhance the outcome. The periosteum has been claimed to increase the regeneration. The egg-shell-derived nano hydroxyapatite (EnHA) has shown a scope as alloplastic graft. Thus, the following study was undertaken to combine the periosteal pedicle along with EnHA for the treatment of intrabony defects under magnification to achieve optimal bone regeneration. A total of 21 patients, having intrabony defects with ≥6 mm probing depth (PD) and two or three wall defects as detected on CBCT, satisfying inclusion criteria were enrolled. The sites were randomly allocated as Group A, B and C (n = 7). The following parameters, defect density and defect fill in CBCT (at baseline and 6 months), PPD, RAL, Plaque index (PI), Gingival index (GI) and Gingival Bleeding Index (GBI) were recorded at baseline, 1, 3 and 6 months. p < 0.05 is considered as statistically significant. Bone density and bone fill values were found to be much higher in pedicle with EnHA and EnHA alone group and the values showed statistically significant results. The current clinical research showed that periosteal pedicle along with EnHA and EnHA as stand-alone therapy gave superior results compared to OFD alone, which is an innovative and feasible treatment option.

Retention and support are needed for removable partial denture stability. The stability can be achieved by clasps, occlusal and cingulum rests on healthy abutment teeth. However, implants or crowns can be used to support the removable partial denture instated on unhealthy abutment teeth. This study was conducted to investigate the fracture strength of two types of all-ceramic restorations used as abutments for the removable partial denture framework. The crowns were manufactured with two types of ceramic materials: zirconia and IPS e.max Press ceramics. The metal alloy (cobalt-chrome) was cast to form the removable partial denture framework. A universal testing machine was used to evaluate the fracture strength of both ceramic crown materials. The results presented no fractures in all-ceramic crowns, but deformation of the partial denture frameworks occurred. With the limitation of this study, it can be concluded that zirconia and IPS e.max Press ceramic can be used as abutments to provide adequate support to the removable partial denture.
