Summary: This study investigated the association between congenitally missing teeth and temporomandibular disorders (TMD). A cross-sectional analysis of 586 control participants and 583 participants with congenitally missing teeth revealed a higher prevalence of TMD in the group with congenitally missing teeth. Therefore, TMJ evaluation and multidisciplinary strategies are necessary when treating patients with congenitally missing teeth.

Summary: Hypodontia has a significant impact on dentofacial features, including retruded lips, tooth position, and facial convexity. The severity of the impact is related to the number of missing teeth, with 5 or more congenitally missing teeth having a greater effect on facial aesthetics.

Summary: This study investigated the effects of EGCG and ethanol wet-bonding on the adhesive-dentin interface stability of primary teeth. The results showed that the dentin bond strength was preserved and nanoleakage reduced in the 0.5% and 1% EGCG groups. Furthermore, the activity of endogenous proteases and the growth of Streptococcus mutans biofilm were inhibited after treatment with 0.5% and 1% EGCG/ethanol solutions.

Summary: Bone augmentation is a common procedure for enhancing and repairing deficient alveolar ridges, and the alveolar ridge splitting procedure is a less invasive option with low morbidity. It allows for widening of narrow ridges to facilitate implant reconstruction in sufficient bone volume. Clinical application of the alveolar ridge splitting procedure requires a learning curve, in-depth knowledge of oral anatomy, and recognition and management of complications.

Summary: Advancements in technology and biomaterials have led to increased use of dental ceramics for aesthetic restorations, with newer materials like zirconia being introduced. Zirconia crowns offer better aesthetics and are more conservative compared to traditional porcelain fused to metal crowns.

Summary: This review examines the epidemiological characteristics of congenitally missing second permanent molars (CMSPMs). A total of 79 studies were analyzed, with a population of 281,968 people. The prevalence of CMSPMs is relatively low, but significant differences were found between continents. Lower CMSPMs were more commonly found in orthodontic samples.

Summary: This study investigated the prevalence of missing and unerupted teeth in OI patients, finding that these abnormalities are related to clinical phenotype, genetic variant type, and treatment methods. The findings suggest that the occurrence of missing and unerupted teeth is associated with the nature of collagen variants and the type of OI.

Summary: Significant advances in adhesive dentistry have been made in recent decades, focusing on improving the mechanical and bonding properties of resin-based dental adhesive materials. The incorporation of functional monomers and silanes has enabled chemical reactions with tooth structure and restorative materials. Simplifying clinical use while ensuring reliability and long-lasting bonds with different substrates is a challenge. Novel monomers, bioactive molecules, and alternative techniques are being developed to address these issues and improve the performance of adhesive materials. The ultimate goal is to achieve simple and reliable bonding without compromising material properties.

Summary: The study demonstrated that ridge preservation was more effective in reducing dimensional loss and bone formation compared to spontaneous healing in extraction sockets of periodontally compromised teeth. The ridge preservation group showed significantly less ridge resorption, less loss in socket height and volume, and lower bone proportion in biopsies compared to the spontaneous healing group.

Summary: This study compared the craniofacial pattern between individuals with or without congenitally missing mandibular incisors. The results showed that the lower incisors of the missing group were more retroclined, resulting in retrusive lower lips. Facial balance also differed between the missing and control groups, and congenitally missing mandibular incisors affected chin morphology, making the chin button prominent.

Summary: A 24-year-old patient presented with complete inability to chew food on the left side of the mouth. Clinical investigation showed a complex malformation of the maxilla with inclined masticatory surface, tooth dysplasia, and eruption failure, resulting in an open bite on the left side. The diagnosis of primary failure of eruption was established. This article presents the clinical picture, surgical management, and further clinical course.

Summary: This systematic review aimed to collect and interpret the randomized clinical trials comparing self-adhesive luting resins with other adhesive protocols. The results showed that postoperative sensitivity might not be affected by the adhesive protocol. Overall, selective etch and self-etch adhesives demonstrated better clinical outcomes compared to self-adhesive resins. Rating: 8 out of 10.

Summary: This article presents an update on the concept of cantilevered single-retainer all-ceramic resin-bonded fixed dental prostheses (RBFDPs) and its clinical application. Through clinical case observations, it is found that restorations made from veneered 3Y-TZP zirconia ceramic can effectively replace single incisors and maintain excellent esthetic outcomes and healthy soft tissues in the pontic area in the long term. Bonding nonretentive oxide ceramics with phosphate monomer-containing luting resins proves to be durable when adequate methods are used.

Summary: This review investigates the clinical observational findings and in-vitro outcomes of thin and ultrathin occlusal veneers using different materials and approaches. It concludes that clinically used 1 mm lithium disilicate overlays and ultrathin one-step no-prep polymer infiltrated ceramic network (PICN) occlusal veneers exhibit high success and survival rates. The analysis of in-vitro studies shows variable survival rates and fracture load values based on materials, thickness, and restorative approaches used.

Summary: The study aimed to investigate the survival, debonding resistance, and failure modes of different occlusal veneer designs used as retainers for posterior cantilever RBFDPs at two tooth wear levels. The results showed that all specimens survived the thermomechanical fatigue loading, and the debonding resistance varied among the different groups. Conservative designs with lingual and proximal bevels were recommended, regardless of the level of tooth wear.

Summary: This study presents a minimally invasive treatment approach for replacing two missing adjacent teeth with two single-retainer resin-bonded fixed dental prostheses (RBFDPs). The RBFDPs were digitally designed and milled from monolithic 3Y-TZP zirconia ceramic using CAD/CAM. The innovative design of the proximal section allowed for different paths of insertion without compromising hygiene.

Summary: The concept of a single midline implant in the edentulous mandible has been a topic of controversial discussion. Initial clinical results showed high implant survival rates and significant improvements in oral comfort, function, patient satisfaction, and oral health-related quality of life for edentulous patients. However, these trials had limitations in terms of sample size and follow-up period. Recent clinical investigations with longer-term observation periods have provided more insights. This overview aims to present the current literature and highlight clinical issues.

Summary: The aim of this study was to measure the wear progress of three high performance polymers (HPP) materials as well as that of zirconia after artificial aging and compare it with the well-documented wear of lithium disilicate. Monolithic zirconia ceramic demonstrated lower wear than that reported for enamel after simulated 5-year of clinical service, whereas all other test materials showed higher volume loss after artificial aging.

Summary: This study evaluated the accuracy of 3D-printed surgical guides before and after sterilization in a steam sterilizer. Forty guides were printed from five resins, and a control group was used. The fit and vertical discrepancies were measured, and the guides were sterilized and repositioned for further measurements. The accuracy was affected by material and sterilization, but clinically acceptable when an increased load was applied during repositioning.
