Brief Summary

This observational study aims to investigate the relationship between periodontal morphology, oral hygiene habits, and non-carious cervical lesions (NCCLs) in adults aged 18-65 years. The main questions it aims to answer are: Is there an association between periodontal soft tissue characteristics and the presence of NCCLs? Are oral hygiene habits and parafunctional behaviors associated with NCCLs? Participants will: Complete a structured questionnaire about oral hygiene habits and oral behaviors Undergo a clinical periodontal examination including assessment of plaque index, gingival index, probing depth, gingival recession, keratinized tissue width, gingival phenotype, and NCCL presence on the maxillary first premolar tooth

Conditions

Gingival Recessions; Non Carious Cervical Lesion

Keywords

non carious cervical lesion; periodontal morphology; oral hygiene habits

Outcome Measures

Primary Outcomes (1)

• Presence of Non-Carious Cervical Lesions

  The presence or absence of non-carious cervical lesions on the maxillary first premolar tooth will be assessed by clinical examination. NCCL will be recorded as a binary outcome: present or absent.

  At baseline / single clinical examination

Secondary Outcomes (3)

• Keratinized Tissue Width

  At baseline / single clinical examination

• Gingival Phenotype

  At baseline / single clinical examination

• Oral Hygiene Habits

  At baseline / single assessment

Study Arms (2)

NCCL Present

Participants presenting with non-carious cervical lesions on the maxillary first premolar tooth during clinical examination.

Diagnostic Test: Periodontal Examination and Oral Habit Assessment

NCCL Absent

Participants without non-carious cervical lesions on the maxillary first premolar tooth during clinical examination.

Diagnostic Test: Periodontal Examination and Oral Habit Assessment

Interventions

Periodontal Examination and Oral Habit Assessment DIAGNOSTIC_TEST

Clinical periodontal examination and questionnaire-based assessment will be performed to evaluate periodontal morphology, oral hygiene habits, and the presence of non-carious cervical lesions (NCCLs). Clinical parameters including probing depth, gingival recession, clinical attachment level, keratinized tissue width, gingival phenotype, plaque index, gingival index, dentin hypersensitivity, and tooth position will be recorded on the maxillary first premolar tooth. Participants will also complete a structured questionnaire regarding oral hygiene behaviors, toothbrushing habits, and parafunctional activities.

NCCL Absent; NCCL Present

Eligibility Criteria

• Age: 18 Years - 65 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Adult patients attending the Faculties of Dentistry at Necmettin Erbakan University and Bilecik Seyh Edebali University for routine dental examination or periodontal evaluation will be recruited for this observational study. Participants will be selected from individuals presenting to the university dental clinics during the study period. The study population consists of community-based dental patients undergoing routine clinical periodontal assessment and questionnaire-based oral health evaluation.

You may qualify if:

• Presence of at least 20 natural teeth
• Periodontally stable individuals without generalized active periodontal destruction
• Systemically healthy individuals or individuals with controlled systemic diseases
• Individuals who voluntarily agree to participate and provide informed consent

You may not qualify if:

• Presence of extensive restoration, caries, endodontic treatment, cervical restoration, crown/bridge restoration, orthodontic brackets, or retainers on the maxillary first premolar tooth
• Missing posterior teeth or edentulous posterior segments
• Ongoing orthodontic treatment
• Severe bruxism or use of occlusal splints/night guards
• Gastroesophageal reflux disease or bulimia nervosa
• Frequent acidic beverage consumption
• Smoking ≥5 cigarettes per day
