Aim: This study aimed at determining the prevalence of non-carious cervical lesions (NCCLs) among patients with gingival recession and identifying the risk factors associated with NCCLs in adult Egyptian patients.
Materials and methods: The present study was conducted on 362 subjects with gingival recession. In 30 patients having NCCLs, full questionnaire and OHIP-14 questionnaires were filled and conventional oral examination was held. Clinical parameters as type of NCCLs, cervical dentine hypersensitivity (CDH), occlusal wear grade, keratinized tissue width, gingival biotype, gingival index (GI) and plaque index (PI) were evaluated.
Results: Prevalence of NCCLs in patients with gingival recession was 5.7% among teeth with gingival recession and 8.3% among patients with 86.7% of lesions class A+ and 60% males. Patients with NCCLs class A+ showed statistically significantly higher occlusal wear grade than patients with NCCL class B+ (P-value <0.001, Effect size = 0.635) and showed statistically significantly higher PI score (P-value < 0.001, Effect size = 0.692).
Conclusion: Prevalence of patients with NCCLs among gingival recession patients is 8.3%. Mandibular left first premolar was the most affected tooth with NCCLs and CDH. Class A+ is significantly associated with higher occlusal wear grade and PI scores than class B+.
