Bone dimensions relationship with gingival phenotype in smokers and nonsmokers using cone-beam computed tomography.

Background: This study aimed to assess the relationship of maxillary alveolar bone thickness (BT) and height (BH) with gingival phenotype (GP) in smokers and nonsmokers using cone-beam computed tomography (CBCT).

Methods: This cross-sectional study was conducted on 60 participants. The participants underwent periodontal examination, and their GP was determined by placing a periodontal probe in the gingival sulcus at the midline and observing the transparency.

Assessing Olfactory Fossa Depth and Its Relationship with the Variations in Adjacent Anatomical Structures by Using Cone Beam Computed Tomography (CBCT).

Unlabelled: This study aimed to investigate the olfactory fossa anatomy (Keros types) and its relationship with changes in adjacent anatomical structures using cone-beam computed tomography (CBCT). In this descriptive-analytical study, the paranasal CBCT of 120 healthy adults over 18 years of age were evaluated. The olfactory fossa depth on both sides and the degree of asymmetry on both sides were reported.

Study of Cytotoxic and Antibacterial Activity of Ag- and Mg-Dual-Doped ZnO Nanoparticles.

A non-laborious process for the fabrication of silver and magnesium dual doped zinc oxide nanoparticles (Ag/Mg-ZnO NP) is described. The wurtzite ZnO nano-structures and the dual doped NP were analyzed by PXRD. SEM data showed the hexagonal morphology of our product, while the gathered anti-bacterial outcomes towards Streptococcus mutans bacteria through micro-dilution technic affirmed the enhanced performance of doped NP compared to the native ones.

Sphenoid Sinus Pneumatization Types and Correlation with Adjacent Neurovascular Structures Using Cone-Beam Computed Tomography.

Unlabelled: This study aimed to assess the sphenoid sinus pneumatization types and their correlation with adjacent neurovascular structures using cone-beam computed tomography (CBCT). This cross-sectional study was conducted on 97 CBCT scans of patients over 18 years of age that were retrieved from the archives of the Oral & Maxillofacial Radiology Department of School of Dentistry. Type of sphenoid sinus pneumatization based on its relationship with sella turcica (conchal, presellar, sellar, and postsellar), the correlation of internal carotid artery (ICA) and optic nerve (ON) with the sinus cavity in the axial and coronal planes (smooth or prolonged type), and presence of Onodi cells and their correlation with the sphenoid sinus (lateral, superior, and superolateral) were all evaluated on CBCT sections.

Comparing dimensions of upper airway in patients with nasal septal deviation and healthy people in CBCT.

Nasal septal deviation causes the obstruction of the nasal lateral wall and sinus cavities as well as bringing some respiratory problems. Furthermore, the obstruction of the upper airway tract can cause changes in normal breathing process, which itself has an important effect on the normal development of both the mandibular and facial areas. This study aimed to assess the dimensions of airway in patients suffering from nasal septal deviation as well as comparing them with healthy individuals through CBCT images.
