Assessment of noncarious cervical lesions in areas of gingival recession specific to the minimally invasive restoration-guided creeping attachment technique: A cross-sectional study.

Background: A noncarious cervical lesion (NCCL) is defined as the loss of tooth structure in the cervical one-third of the tooth due to causes other than dental caries. Descriptive epidemiological studies on NCCLs are justified because of their high frequency and their potential consequences for the periodontium. The present study aimed to analyze the trend of NCCLs in teeth with gingival recession, determine the prevalence and associated risk factors for these combined lesions, and evaluate patient acceptance of various treatment modalities, with emphasis on the minimally invasive restoration-guided creeping attachment (RGCA) technique. Materials and Methods: A total of 150 patients were enrolled in the present study. A total of 1200 teeth were examined clinically using ×3.5 magnification loupes and a UNC-15 probe to evaluate the cementoenamel junction and step-like defects according to the Pini-Prato classification of gingival recession. All patients were interviewed regarding potential etiological factors using a specially designed questionnaire. The questionnaire also included attitudinal factors related to willingness for treatment in general and specifically for the RGCA technique. Results: Among the 1200 teeth with exposed root surfaces, 543 exhibited Class A - defects, 442 Class A+, 149 Class B+, and 66 Class B- defects. The distribution of combined defects across tooth types was incisors 39%, premolars 32%, canines 22%, and molars 6%, with 92% located in the anterior esthetic zone. Conclusions: Combined lesions were predominantly found in incisors, premolars, and canines located within the smile arc.
