“…The prevalence of NCCLs was 22.7% in the present study. This value is slightly higher than the range of 15-20% reported in previous studies (22)(23)(24). The higher prevalence in our study may be due to the fact that the participants included children at special needs schools, who may lack manual dexterity and have inadequate knowledge of oral hygiene practices.…”

“…Sognnaes et al 15 observed extracted teeth that exhibited wedgeshaped NCCLs within silicate and amalgam restorations. This phenomenon could result from abrasion, but is unlikely to be explained by abfraction because the properties of amalgam and silicate restorations are notably different to those of dental hard tissues.…”

Non-carious cervical lesions involve loss of hard tissue and, in some instances, restorative material at the cervical third of the crown and subjacent root surface, through processes unrelated to caries. These non-carious processes may include abrasion, corrosion and possibly abfraction, acting alone or in combination. Abfraction is thought to take place when excessive cyclic, non-axial tooth loading leads to cusp flexure and stress concentration in the vulnerable cervical region of teeth. Such stress is then believed to directly or indirectly contribute to the loss of cervical tooth substance. This article critically reviews the literature for and against the concept of abfraction.Although there is theoretical evidence in support of abfraction, predominantly from finite element analysis studies, caution is advised when interpreting results of these studies because of their limitations. In fact, there is only a small amount of experimental evidence for abfraction. Clinical studies have shown associations between abfraction lesions, bruxism and occlusal factors, such as premature contacts and wear facets, but these investigations do not confirm causal relationships. Importantly, abfraction lesions have not been reported in pre-contemporary populations.It is important that oral health professionals understand that abfraction is still a theoretical concept, as it is not backed up by appropriate clinical evidence. It is recommended that destructive, irreversible treatments aimed at treating so-called abfraction lesions, such as occlusal adjustment, be avoided.

“…Striking changes both the pattern and distribution of oral diseases causes tooth wear, it has been estimated that 25% of tooth destruction does not originate from caries process. 1,4,[9][10][11][12][13] Most common problems associated are non-carious destruction of teeth. Tooth wear or tooth surface loss refers to the pathological loss by a process other than dental caries.…”

Objectives: To attain alliance between the oral hygiene practices with prevalence of tooth abrasion among urban and rural adult population of Central India. To plan dental care services in inaccessible areas and to suggest appropriate remedial measures to prevent this avertable and self-inflicted injury of teeth in this cross-sectional study. Materials and methods:A sum of 1045 adult residents both from Urban (529) and rural (516) parts of Bhopal district (Central India) was selected on a random basis. The multistage sampling technique was adopted to ascertain the sample size. In urban area the study population consisted of 240 males, 289 females and 201 males and 315 females in rural area respectively. All residents above 18 years of age from the Bhopal district were included in cross-sectional study. Assessment form comprises of questionnaire and general information on oral hygiene practices, dietary habits and medical history. Abrasion was assessed using diagnostic criteria recommended by Smith and Knight (modified). Chi-square test was used to test associations between categorical variables at 5% level of significance. Regression analysis attempted to define for risk factors causing abrasion. Literature on the prevalence of abrasion is very sparse, so attempt is made to correlate the etiological factors and recommend to prevent tooth wear.Results: Investigation of this cross-sectional study was aggregate of 1045 residences. Result shows high prevalence of abrasion 70.2%. Higher prevalence concomitant with diffident habits related to oral hygiene maintenance was recorded more among rural (76.9%) when compared to urban dwellers (63.7%). Presence of abrasion verifies statistical significance in relation to age, ruralurban difference and variations in habit of oral hygiene care. Stated in the present study, avertable and self-inflicted is toothabrasion, recurrently resulted by the reprehensible brushing method and common use of indigenous material for the maintenance of oral hygiene.Conclusion: Shows significant liaisons with the presence of abrasions in relation to Urban and rural dwelling, age, material used and mode of brushing and duration of brushing. Indigenous and course material causes high amount of enamel wear and with the advancement in age abrasion tend to increase. Prevalence of abrasion does not show any gender predilection.Cultural believes, lifestyle and transition reflects in deviating presence of abrasion in populations.
