Objectives: The objective of this review was to assess clinical trials that have examined the materials, design, and bonding of ceramic cantilevered resin‐bonded fixed dental prostheses (RBFDPs) as a potential option for replacing missing anterior teeth. The evaluation primarily focuses on the rate of restoration failure and clinical complications. Materials and Methods: A thorough search of databases including PubMed/MEDLINE, Scopus, and the Cochrane Library, was conducted. The most recent search was performed in October 2023. Clinical studies that compared ceramic cantilevered RBFDPs with double retainers or cantilevered RBFDPs using different ceramic materials or bonding systems were included. The outcome measures considered were restoration failure and complication rates. Results: Twelve studies met the eligibility criteria. The pooled data showed a statistically significant decrease in complication events when using cantilever designs compared with double retainer designs (p < 0.05); however, there were no differences found between the two designs in terms of restoration failure. The complication and failure rate of cantilever RBFDPs did not show a statistically significant difference with or without ceramic primer application before luting with phosphate monomer‐containing luting resin (p > 0.05). Conclusions: Ceramic cantilevered RBFDPs have lower complication rates compared with those with double retainers. The use of a ceramic primer prior to luting composite resin for ceramic cantilevered RBFDPs decreases the occurrence of complications and failures, although this effect was not statistically significant. Additional research is required to confirm these findings. Glass ceramic cantilever RBFDPs showed a decrease in success after 6 years, requiring ongoing monitoring, but both zirconia and glass‐infiltrated alumina cantilever RBFDPs have demonstrated durability with excellent long‐term success and survival rates for up to 10 and 15 years. Clinical Significance: Cantilever ceramic RBFDPs in the anterior region are a less invasive and valuable treatment option, providing good esthetic results. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study is to investigate the type of ridge (degree of angulation of the lingual concavity) and the buccolingual dimensions in the area of the first and second molars in both genders of different ages and how this will affect implant placement in the posterior mandible. Materials and Methods: This retrospective cross‐sectional study comprised cone beam computed tomography images of 150 dental patients (75 males and 71 aged ≥30). The following were measured/reported: type (morphology) of the ridge (convex [C], parallel [P], or undercut [U]), buccolingual width at the base and the crest of the ridge, and ridge height. The concavity angle, depth, and length of the U‐shaped ridge were measured too. Results: The prevalence of type U ridge ranged from 32.7% in the first molar region to 62.7% in the second molar region. Almost all measurements and ridge type distributions were comparable amongst the age groups (p >.05). Very few significant differences were found when comparing #36 versus #37 and #46 versus #47 teeth, with no differences in the distribution of the ridge types (p >.05). Quite the inverse, all measurements were statistically different when comparing #36 versus #37 and #46 versus #47 teeth, and type U ridge was more frequent in second molar compared to the first molar regions, respectively (p <.05). Many measurements were statistically higher in females; the inverse was true for a few measurements (p <.05). Type U ridge in #36 and #37 was found more frequently among males (p <.001). In contrast, the ridge types in #37 and #47 were not statistically different gender‐wise. Conclusions: The U type of ridge was more prevalent in the investigated population, encountered more frequently in the second molars generally and in the first molars of males than females. Most posterior mandibular measurements are similar age‐ and side‐wise but seem different gender‐ and tooth‐wise. [ABSTRACT FROM AUTHOR]

Purpose: This systematic review and meta‐analysis aimed to summarize available evidence regarding the effect of horizontal glass fiber posts (HGFPs) on fracture strength and fracture pattern of endodontically treated teeth (ETT) compared to controls without HGFP. The review protocol was registered on the OSF registries. Methods: Literature searches were conducted in MEDLINE/PubMed, Scopus, Web of Science, Embase, Google Scholar, and ProQuest for all relevant studies published up to February 2022. All in vitro studies that assessed the influence of HGFPs on fracture strength and fracture pattern of ETT whether mesio‐occluso‐distal or mesio‐occlusal or DO cavities were considered eligible. Review Manager (RevMan) was used for the meta‐analysis. Subgroup and funnel plot analyses were also performed. Quality assessment was conducted by two independent reviewers. Results: A total of 12 articles met the inclusion criteria, and 10 studies underwent quantitative evaluation. The pooled effect showed that fracture resistance of molar teeth restored with HGFP was significantly higher than teeth without HGFP (standardized mean difference [SMD]: 1.61, 95% confidence interval [CI]: 0.14, 3.09, p = 0.03), whereas marginally significant for premolars (SMD: 1.36, 95% CI: −0.00, 2.73, p = 0.05). Regarding fracture patterns, the presence of an HGFP significantly increased the occurrence of restorable fracture patterns for premolars (odds ratios [OR]: 4.15, 95% CI: 1.60, 10.82, p = 0.004) compared to controls, whereas the difference was not significant for molars (OR: 1.09, 95% CI: 0.43, 2.77, p = 0.85). Moderate risk of bias was identified in 9/12 studies; one study showed a high risk of bias and two studies showed a low risk of bias. Conclusions: Within the limitations of this study, there is evidence from in vitro studies that the use of HGFP increases the fracture resistance of the ETT when compared to teeth without HGFP and also reduces the occurrence of non‐restorable fractures for premolars. However, well‐conducted in vitro and prospective clinical studies are warranted to validate this finding. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effect of calcium hydroxide intracanal medicament on the push‐out bond strength of resin‐based and calcium silicate‐based endodontic sealers. Methods: A comprehensive search of was conducted for all relevant in‐vitro studies. All randomized controlled in‐vitro studies that evaluated the effect of calcium hydroxide on the push‐out bond strength of resin‐based or calcium silicate‐based endodontic sealers were assessed. The variables of interest were extracted, and the risk of the included studies was evaluated. The standardized mean difference was calculated and the significance level was set at p value <0.05. Results: A total of 26 studies were eligible for analysis. There were 45 independent comparison groups and 1009 recruited teeth. The pooled data showed no significant difference in push‐out bond strength between calcium hydroxide and control group in the resin‐based group (SMD = 0.03; 95% CI = −0.55, 0.60; p = 0.93), and calcium silicate‐based group (SMD = 0.02; 95% CI = −0.31, 0.35; p = 0.90). Most of the studies (21 out of 26) were at medium risk of bias and five studies showed a low risk of bias. Conclusion: The available evidence suggests that calcium hydroxide used as intracanal medication does not influence the push‐out bond strength of the resin‐ and calcium silicate‐based endodontic sealers. Clinical significance: The results of this meta‐analysis suggest that calcium hydroxide used as intracanal medication does not influence the push‐out bond strength of resin‐based and calcium silicate‐based endodontic sealers.

Purpose: The fracture resistance of dental post systems is influenced by the material of the post. The purpose of this systematic review and meta‐analysis was to assess if there is a difference in fracture resistance between prefabricated dental titanium posts and fiber posts. Methods: An online electronic search was performed using the PubMed, Scopus, and Web of Science databases for in vitro studies published from 2010 to 2020 in English. The retrieved eligible studies that compared the fracture resistance of titanium and fiber posts on human teeth were selected. The pooled standardized mean difference (SMD) with a 95% confidence interval was calculated. In addition, the trial sequential analysis (TSA) was performed to test if the available studies are sufficient to make conclusive evidence. Results: Of the 1165 retrieved studies, 17 studies were included in the qualitative analysis, while 16 studies were included in the quantitative analysis. Because of the high heterogeneity among studies, data from 10 studies were pooled and submitted to TSA. A total of 852 teeth were evaluated for fracture of the posts in 27 independent comparison groups. The pooled effect of the residual studies revealed no significant difference between titanium and fiber posts (SMD = –0.12; 95% CI = –0.30, 0.06; p = 0.20). Results of the TSA revealed no conclusive evidence. Conclusions: The results of the current evidence revealed no significant difference between fiber and titanium posts. The evidence is insufficient, and more standardized in vitro studies are required. [ABSTRACT FROM AUTHOR]

Objectives: The purpose of the present systematic review and meta‐analysis was to assess the available evidence regarding the efficacy of curcumin mouthwashes on plaque and gingivitis. Methods: A comprehensive online search of multiple databases (PubMed, Scopus, Web of Science, and Google Scholar) was performed to identify all relevant studies published up to August 2020, using the following keywords: curcumin, turmeric, gingivitis, periodontal health, and plaque control. All clinical trials that compared the efficacy of curcumin mouthwash with chlorhexidine in controlling dental plaque and gingivitis were included. Data were analysed using Review Manager (RevMan) 5.3 software. The risk of bias was evaluated by two independent reviewers using the Cochrane assessment tool. Results: Six randomized clinical trials (comprising 320 subjects) fulfilled the eligibility criteria. Five studies showed a high risk of bias and only one study showed a low risk of bias. The pooled data of the six included studies revealed comparable efficacy of curcumin and chlorhexidine in reducing dental plaque (I2 = 91%; standardized mean difference [SMD]: 0.27, 95% CI: −0.53, 1.07, p = 0. 51) and gingival inflammation (I2 = 40%; SMD: −0.13, 95% CI: −0.35, 0.09, p = 0.24), with no statistically significant differences between the two groups. Conclusion: The results suggest that curcumin mouthwashes have promising anti‐plaque and anti‐gingivitis properties. Further clinical trials with adequate sample sizes and standardized methodologies are required to discern the efficacy of curcumin mouthwash in reducing plaque and gingivitis. [ABSTRACT FROM AUTHOR]
