Prevalence of non-carious cervical lesions and orthodontic treatment: a retrospective study

Abstract

Background This study aimed to assess the distribution of non-carious cervical lesions (NCCLs) by tooth type, investigate the prevalence of NCCLs in patients undergoing orthodontic treatment, and identify the possible associated factors. Material and methods A total of 160 patients were enrolled in this retrospective study. Data on the following variables were collected from pre-and post-orthodontic treatment records: age, sex, Angle’s malocclusion, facial pattern, number of activation sessions, compensatory treatment, and retreatment. Frontal, right and left lateral intraoral photographs of each patient were evaluated to identify the presence or absence of NCCLs in each tooth and assess the distribution of NCCLs in the 3840 teeth from the enrolled patients. Furthermore, patients were classified as NCCLs present, irrespective of the number of NCCLs on the teeth or NCCL absent. Bivariate and multivariate Poisson regression analyses with robust variance were used to assess the association between the NCCLs and each independent variable. Prevalence ratio and 95% confidence intervals were calculated and p < 0.05 was considered statistically significant. Results The prevalence of NCCLs before and after orthodontic treatment was 22.71% and 30.91%, respectively. Premolars were the most affected teeth, followed by the first molars, canines, and incisors. After statistical analysis, age was found to be the variable factor that influenced the prevalence ratio, with NCCL being the most prevalent when orthodontic treatment was performed in adulthood. Conclusions Premolars were most commonly affected by NCCLs. Furthermore, age seemed to contribute to the increased prevalence of NCCLs in adults undergoing orthodontic treatment.

Effects of occlusal wear on 16‐year progression of non‐carious cervical lesions–Results of the study of health in Pomerania (SHIP‐START)

“…For longitudinal analyses, 226 probands were available (Figure 1). Analysis of OW and NCCLs was performed on premolars and molars only, as substance loss appears mainly in lateral teeth 16 . OW was recognised as flat attritional wear facets due to friction between opposing teeth.…”

“…only, as substance loss appears mainly in lateral teeth. 16 OW was recognised as flat attritional wear facets due to friction between opposing teeth. Pitting and gauge marks of the dentin as signs of abrasion were only considered when surrounding enamel exhibited flat facets.…”

cross-sectional study on the etiological causes of cervical lesions among patients without caries in Lahore, Pakistan

“…The dental structure's weakness is basically caused by malocclusion and occlusal interferences enhancing the stress concentration in the cervical area. This stress concentration is basically increased by numerous factors such as age, orthodontic movement type, root length, surgery time span, and severity of malocclusion, root length and bone loss amount [23]. Another study considered other variables such as gender, craniofacial pattern and the type of malocclusion that influences the NCCLs' prevalence [24].…”

The link between Noncarious Cervical Lesions (NCCL) and gingival recession. Etiology and treatment. A narrative review.

“…It is currently incorrect to label a single mechanism as causing all types of NCCL. Thus, the current state in the field of study mentions a multifactorial etiology of NCCLs [1,[3][4][5][6][7][8]. Once tooth decay is ruled out as the origin of this condition, other factors involved must be recognized.…”
