Brief summary
The purpose of this cross-sectional study is to evaluate the morphometric properties of trabecular bone quality using Cone-beam computed tomography in periodontal disease at different stages, comparing smokers and non-smokers.
Detailed description
This cross-sectional study aimed to analyze changes in trabecular bone quality associated with smoking inindividuals with periodontal disease using morphometric analysis of Cone Beam Computed Tomography (CBCT)images. Materials-Methods: The study involved 90 systemically healthy patients who were smokers (\>=10cigarettes/day) or non-smokers, and were indicated for CBCT.Clinical periodontal parameters (plaque index, gingival index, probing pocket depth, bleeding on probing, clinicalattachment loss (CAL)) were recorded. Participants were divided into two main groups based on smoking statusand three subgroups based on periodontal diagnosis: gingivitis, Stage I-II periodontitis, and Stage III-IVperiodontitis (n=15). Mandibular first molars and central incisors without prosthetic restorations, endodonticlesions, or root canal treatments were included. Two volumetric regions of interest (ROIs) with dimensions of5x5x10 mm were selected around the apices of these teeth: posterior ROI and anterior ROI. Trabecular bonemicro-architecture was analyzed using the BoneJ plugin for morphometric parameters: anisotropy (DA), bonevolume fraction (BV/TV), trabecular thickness (Tb.Th), and trabecular separation (Tb.Sp). Statistical analysis wasperformed using Student's t-test, one-way ANOVA, and Kruskal-Wallis tests.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bone morphometric parameters | Baseline | The microarchitecture of trabecular bone was analyzed by measuring bone morphometric parameters (BMPs) using the BoneJ plugin of the software. Degree of Anisotropy (DA): This parameter assesses the directional characteristics of trabecular bone. A DA value of 1 indicates an isotropic structure, while values above 1 indicate anisotropy. DA is calculated as the ratio of the longest mean intercept length vector to the shortest. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical periodontal parameters | Baseline | A single calibrated operator (I.C.) performed the periodontal assessment utilizing an intraoral mirror and William's periodontal probe. Plaque Index (PI): The PI assesses the thickness of plaque along the gingival margin. After drying the teeth, the examiner visually inspects the surfaces of the teeth. Scores are assigned based on the presence and thickness of plaque on the gingival third of the tooth surface, usually on a scale from 0 (no plaque) to 3 (abundant plaque accumulation). |
