Dental caries is known as the destruction of dental hard tissues by acidic by-products from bacterial metabolism of dietary carbohydrates (Selwitz et al. 2007). Despite the great efforts in caries prevention, it is still one significant public health problem globally, and dental restorations are the most commonly used approach to restore decayed teeth (Selwitz et al. 2007). Apart from that, restorations also play an essential role in clinical treatment, including tooth wear, dental trauma, and esthetic purposes. Although all kinds of restorative materials emerge in an endless stream, there are generally two common categories of restorative dental materials: direct and indirect materials, both have their specific indications for clinical use (AFFAIRS ACOS 2003). The former category includes most commonly used filling materials like amalgam, resin composites, glass ionomer cement (GIC), etc., which are placed directly into a tooth cavity and shaped intraorally. The indirect restorations are fabricated outside of the mouth via dental impressions of a prepared tooth, such as crowns, inlays and onlays, bridgework, and veneers (Loomans and Özcan 2016).

Tooth wear develops secondary to mechanisms that can be grouped as erosion, attrition, and abrasion occurring independently or in combination. An example of a common exacerbating factor is hyposalivation. The potential consequences of long-standing tooth wear include hypersensitivity secondary to dentine exposure, reduced masticatory function and poor dental aesthetics.
Paleopathology and paleomedicine
Published in Lois N. Magner, Oliver J. Kim, A History of Medicine, 2017
Despite the increasing sophistication and power of the analytical techniques employed in the service of paleopathology, many uncertainties remain, and all results must be interpreted with caution. Since the last decades of the twentieth century, scientists have exploited new methods, such as DNA amplification and sequencing, the analysis of stable isotopes of carbon and nitrogen, and scanning electron microscopy to ask questions about the health, lifestyle, and culture of ancient peoples. Scanning electron microscopy has been used to examine patterns of tooth wear and enamel defects caused by stress and growth disruption and the effect of workload on the structure of bones. Where possible, chemical investigations of trace elements extracted from ancient bones and hair can provide insights into dietary patterns and quality of life. Lead, arsenic, mercury, cadmium, copper, and strontium are among the elements that can be identified in hair.
Deterioration of direct restorative materials under erosive conditions with impact of abrasion and attrition in vitro

Tooth wear is an irreversible, physiological phenomenon that may be classified into several categories: abrasion (tooth wear in the presence of a foreign medium), erosion (acid-induced tooth wear) and attrition (wear as a consequence of tooth-to-tooth contact) [1]. Excessive consumption of acidic foods or regurgitation of the gastric acid in the oral cavity may chemically induce tooth substance loss [2,3]. Moreover, when acid softens the tooth surface, it becomes susceptible to physical impacts, namely abrasion and attrition [4]. The process of wear is more severe in some patients, for example those suffering from parafunctional habits [5]. Excessive wear often causes exposure of dentine canals and tooth pulp. Clinically, this manifests as hypersensitivity and pain, reduced chewing efficiency and discolorations [6,7].
Knowledge about caries and erosive tooth wear is confused among Norwegian high school students

Our results showed that students performed better in determining which beverages that has potential to induce erosive tooth wear than they did in determining which beverages may induce caries. This is an important finding because frequent consumption of acidic beverages is the main extrinsic cause of erosive tooth wear. In line with our findings, Verploegen and Schuller [19] found that young adults (20–25-year olds) in the Netherlands lacked knowledge about erosive tooth wear. However, participants in their study generally scored higher on questions regarding the dental erosion potential of different beverages than the participants in our study. This might be due to the age difference between the two samples surveyed. Another explanation might be that Verploegen and Schuller [19] asked exclusively about erosive tooth wear (i.e. no questions addressed caries). Accordingly, the addition of questions related to caries in the present study might have confused the students, resulting in their lower scores.
Asthma, long-term asthma control medication and tooth wear in American adolescents and young adults
Published in Journal of Asthma, 2021
Udeshman Goswami, Saoirse O’Toole, Eduardo Bernabé
The present findings have implications for practice and future research. Dental professionals should be aware of a possible association between asthma medication and tooth wear and should look for evidence of tooth wear among asthmatic patients under long-term control medications. Further research should advance on the specific medications associated with tooth wear and potential mechanisms. Methylxanthines were not reported by participants in our study sample but are worth exploring. Like long-acting beta-agonists and leukotriene modifiers, they are suggested as a link between asthma and GERD by relaxing smooth muscles tone, including the gastroesophageal sphincter (12–14). Additional information on long-term asthma control medication should include the route of drug delivery (liquid, inhaler, nebulizer), frequency of drug administration and duration of treatment, which are important factors for tissue damages, especially in case of treatment of chronic conditions. Longitudinal studies measuring changes in asthma, medications and outcome as well as with a stringent control for confounders (GERD diagnosis) would be beneficial.
