Objective This article is aimed at providing an overview of the topic of erosive tooth wear (ETW), highlighting the clinical signs, diagnosis, and management of dental erosion. Overview With the increased prevalence of ETW, it is important that oral health professionals are able to recognize the early signs. Early clinical signs of dental erosion are characterized by loss of enamel texture, a silky glossy appearance, and sometimes a dulling of the surface gloss, referred to as the “whipped clay effect, cupping, and restorations ‘standing proud’.” The progression of ETW should be monitored by means of diagnostic models or clinical photographs. ETW can be as a result of acid attack of extrinsic or intrinsic origin. Conclusion There is an increase of ETW that is being recognized by the profession. The first step in diagnosing and management is to recognize as early as possible that the process is occurring. At that point a determination of whether the primary etiology is either intrinsic or extrinsic should be made. If these findings are confirmed, appropriate prevention, and management strategies can be adopted followed by appropriate restorative therapy. Clinical Significance The prevalence of ETW continues to increase. It is therefore important that oral health care providers have a better understanding of the etiology, pathophysiology, and management of this condition. This review aims to provide the guidelines for diagnosis and management of dental erosion.

Objective: In this article, the potential oral health consequences of vaping are described. While most dentists are likely aware of the potential serious health effects involved with vaping, the aim of this article was to raise awareness on identified oral health consequences. Clinical considerations:Three patients presented to one dental practice with unusual patterns of dental caries, and all three admitted to regular vaping. Vaping components include propylene glycol, glycerin, nicotine, and flavors, which contain sucrose, sucralose, and ethyl maltol. The vapor produced by vaping devices is thick and viscous and much of it is retained on oral tissues. There are over 10 000 different vaping liquids, including some that contain tetrahydrocannabinol (THC) and vitamin E acetate. Vaping clearly has the potential to negatively affect general health, periodontal health, and accelerate the development of caries. There is also evidence that teenagers are being attracted to vaping in astonishing numbers. Conclusions:The general health consequences of vaping have received considerable attention in the national media. There is much to be learned about the consequences of this behavior. There are also potential serious oral health consequences to vaping.It is likely that the composition of certain vaping solutions may make them more harmful than others Clinical significance: It is important that dental professionals are made aware of the potential problems related to vaping. Initial reports show that the effect of ecigarettes on periodontal tissues is similar to that of conventional cigarettes. Some vaping formulations may be highly cariogenic, especially those with sweet flavors, which are used to attract young people. Patients should be routinely questioned about their vaping habits in the medical-dental history. K E Y W O R D Scarrier, dental caries, nicotine, THC, vaping, vaping solution, viscous aerosol

Purpose: This study was done to compare the survival rates of cast gold and ceramic onlays placed in a dental school setting. Material and Methods: An electronic search was conducted in the patient records at Adams School of Dentistry, University of North Carolina at Chapel Hill for onlay codes that were in the database (From 1998 until 2018). Progress notes and radiographs were scrutinized to establish the survival time of the restorations. Any complications that occurred during the life time of the restorations were noted. The survival was summarized by categorization based on ranges of survival time in years; group 1: 1 to 5 years, group 2: 6 to 22 years. The mean survival time and standard deviation were calculated. One-way ANOVA was used to determine whether there was a statistically significant difference in the survival times between gold and ceramic onlays. Results: The mean survival rate of cast gold onlays (86.6%) was comparable to that of ceramic onlays (81.1%). The gold onlays in Group 1 had a higher mean survival time (2.43 years) than the ceramic onlays (2.03 years). This difference was statistically significant (p = 0.002). The ceramic onlays in Group 2 had a mean survival time of 19.75 years while gold onlays had a mean survival time of 17.63 years. This difference was not statistically significant (p = 0.91). Conclusion: It was concluded that while the survival rate of ceramic onlays (81.1%) was inferior to that of cast gold onlays (86.6%), it was comparable
