The impact of different dental restorations on detection of proximal caries by cone beam computed tomography.

Objectives: To evaluate the effects of different types of restorations on observer ability to detect proximal caries in CBCT images.

Materials And Methods: Forty human premolars and molars with artificial proximal caries were placed proximal and distal to 5 molars having different restorations (amalgam, composite, resin-modified glass ionomer cement (RMGIC) fillings, zirconia, and lithium disilicate crowns) and a non-restored molar. CBCT scans were obtained using i-CATNext Generation.

Tooth Agenesis in Patients with Complete Bilateral Cleft Lip and Palate.

Aim: The aim of this study was to compare the number of teeth in the premaxilla (cleft area) and to assess the presence of tooth agenesis with the ultimate goal of finding whether differences existed in the two suggested subtypes of nonsyndromic bilateral cleft lip and palate (BCLP) patients.

Settings And Design: A retrospective comparative study was conducted, where cone- beam computed tomography (CBCT) images of 22 BCLP patients (10 males and 12 females, with age range 8 to 14, mean age 9.6 years) obtained from archive of Cleft Clinic, affiliated to the Oral and Maxillofacial Surgery department, Ain-Shams University, Cairo, Egypt were assessed.

Cone Beam Computed Tomography Analysis of Oropharyngeal Airway in Preadolescent Nonsyndromic Bilateral and Unilateral Cleft Lip and Palate Patients.

Objective: The objective of this study was to assess the volume, area, and dimensions of the oropharyngeal airway (OPA) in a previously repaired nonsyndromic unilateral cleft lip and palate (UCLP) versus bilateral cleft lip and palate (BCLP) patients when compared with noncleft controls using cone beam computed tomography (CBCT).

Design: This was a retrospective case-control study.

Setting: The Cleft Care Center and outpatient clinic that are affiliated to our faculty were the settings for the study.

Cone-Beam Computed Tomography Analysis of the Nasopharyngeal Airway in Nonsyndromic Cleft Lip and Palate Subjects.

Objective: To assess the nasopharyngeal airway volume, cross-sectional area, and depth in previously repaired nonsyndromic unilateral cleft lip and palate versus bilateral cleft lip and palate patients compared with noncleft controls using cone-beam computed tomography with the ultimate goal of finding whether cleft lip and palate patients are more liable to nasopharyngeal airway obstruction.

Design: A retrospective analysis comparing bilateral cleft lip and palate, unilateral cleft lip and palate, and control subjects. Significance at P ≤ .
