About this study

Official title: Relationship Between Periodontal Morphology, Oral Habits, and Non-Carious Cervical Lesions: A Cross-Sectional Observational Study

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?

Read more

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

Read the detailed description

Periodontal morphology and oral hygiene behaviors may play an important role in the development of non-carious cervical lesions (NCCLs), which are characterized by the loss of dental hard tissue at the cervical region of the tooth without the presence of dental caries. NCCLs are considered multifactorial conditions associated with mechanical stress, toothbrushing habits, parafunctional behaviors, and periodontal soft tissue characteristics.

This cross-sectional observational study is designed to investigate the relationship between periodontal morphology, oral hygiene habits, and the presence of NCCLs in adults aged 18-65 years attending the Faculty of Dentistry of Necmettin Erbakan University. A total of 180 participants are planned to be included.

Clinical periodontal examination will be performed on the maxillary first premolar tooth. The evaluated parameters will include probing depth, gingival recession, clinical attachment level, keratinized tissue width, gingival phenotype, plaque index, gingival index, dentin hypersensitivity, and the presence of NCCLs. Tooth position and parafunctional habits associated with occlusal stress will also be recorded.

Participants will complete a structured questionnaire regarding demographic characteristics, oral hygiene practices, toothbrushing frequency and technique, toothbrush type, brushing force, and oral habits.

The primary objective of the study is to determine whether periodontal soft tissue characteristics and oral hygiene-related behaviors are associated with the presence of NCCLs. Statistical analyses will include descriptive statistics, group comparisons, and multivariable logistic regression analyses to identify factors independently associated with NCCLs.

  • Periodontal Examination and Oral Habit AssessmentDiagnostic 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: At baseline / single clinical examination

Secondary outcomes (3)
  1. Keratinized Tissue Width

    Keratinized tissue width will be measured in millimeters from the free gingival margin to the mucogingival junction at the mid-buccal aspect of the maxillary first premolar tooth.

    Measured: At baseline / single clinical examination

  2. Gingival Phenotype

    Gingival phenotype will be evaluated using periodontal probe transparency and classified as thin or thick phenotype.

    Measured: At baseline / single clinical examination

  3. Oral Hygiene Habits

    Oral hygiene habits including toothbrushing frequency, toothbrush type, brushing technique, and brushing force will be assessed using a structured questionnaire.

    Measured: At baseline / single assessment

Questions about this trial

What is this clinical trial studying?

An observational study of Non Carious Cervical Lesion and Gingival Recessions, run by Bilecik Seyh Edebali Universitesi at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Presence of Non-Carious Cervical Lesions (time frame: At baseline / single clinical examination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2026.
