Prevalence of Non-Carious Tooth Wear in Patients

Abstract

Non-carious lesions caused by tooth wear include hypersensitivity, bad oral cleanness (plaque formation), cosmetic complications and tooth fractures. It is associated with a number of dental problems if present. Objective: To determine the frequency of non-carious lesions in tooth wear among patients attending the dental OPD. Methods: A descriptive and cross-sectional study which was carried out in the Dental department of Army Medical and Dental College Rawalpindi for one-year duration from January 2021 to December 2021. After formal approval by the Ethics Review Committee; regardless of the gender, 180 subjects of age 20-60 years were studied by means of the Tooth Wear Index of Knight and Smith. Five surfaces of each tooth were examined in the maxillary and mandibular arches: buccal (B), cervical (C), lingual (L) and occlusal /incisal (O and I). Results: It was instituted that non-carious tooth wear prevalence was probable in premolars trailed by molars and less pronounced in incisors. The surfaces of O&I were most susceptible to injury, trailed by the surfaces of cervical. The carious tooth wear was less likely in lingual surfaces. Descriptive statistical analysis was used to obtain results on the incidence of non-carious tooth wear by giving the median, standard deviation and mean. Conclusions: Premolars and molars are the teeth mostly affected by non-carious tooth wear, and the incisors are the minimum teeth which are affected. The surfaces most affected were O&I, trailed by the cervical surface with a lower incidence of lingual surface lesions.

“…On the other hand, the results are inconsistent with those of Ali et al [ 11 ], who reported that non-carious tooth wear mainly affects premolars and molars, whereas incisors are the least affected teeth. Occlusal and incisal were the most affected areas, followed by the cervical surface, and the least frequency of lesions was on the lingual surface [ 1 ]. The study of Ali et al [ 11 ] is another study that found contradicting results; they found that the most affected tooth wear was recorded in mandibular molars (15.8%), followed by maxillary incisors (8.8%), then mandibular incisors (5.3%), and maxillary molars (2.6%).…”

“…Attrition is the loss of tooth substance or a restoration caused by mastication or contact between occluding surfaces, while erosion is the progressive loss of hard dental tissues by chemical processes not involving bacterial action. Abrasion, by contrast, is the pathological loss of tooth substance caused by abnormal and repetitive mechanical wearing other than tooth-to-tooth contact [ 1 ].…”

The Severity of Tooth Surface Loss in Adult Patients Presenting to a Private Dental Hospital

“…In a Pakistani study, it was reported that tooth wear impacts the occlusal surface of molar teeth more as compared to the cervical surfaces followed by the incisors (8). Another study indicated that non carious cervical lesions mainly affects molars and premolars (9). The causes mainly include age, diet, medications, chemical insults, pathologies, poor oral hygiene, consumption of carbonated drinks, and cultural practices like beetle nut chewing and dental habits including attrition, abrasion, erosion and abfraction (8,9).…”

The study referenced employed the TWI by smith and Knight to assess and quantify tooth patterns and leisions.…”
