Objective: The purpose of this work was to evaluate orofacial airway dimensions and the position of the hyoid bone related to changes induced by facemask therapy (combined with rapid palatal expansion) or by chincup therapy as compared to an untreated Class III control group.
Methods: In all, 67 patients with skeletal Class III malocclusion were divided into a facemask group (n = 25; 15 girls and 10 boys), a chincup group (n = 15; 16 girls and 9 boys), and a control group (n=17; 9 girls and 8 boys). Hard- and soft-tissue parameters were analyzed on lateral cephalograms, which were available for all patients and included a baseline radiograph (T1) obtained before treatment and a follow-up radiograph (T2) taken upon completion of active treatment or, in the control group, after a 6-month interval.
The aim of this study was to investigate the effect of preheating on microshear bond strength (MSBS) of silorane and methacrylate-based composite resins to human dentin. The teeth were randomly divided into three main groups: (1) composite resins were heated upto 68 °C; (2) cooled to 4 °C; and (3) control [room temperature (RT)]. Each group was then randomly subdivided into four subgroups according to adhesive system used [Solobond M (Voco), All Bond SE (Bisco), Clearfil SE Bond (CSE) (Kuraray), Silorane adhesive system (SAS) (3M ESPE)].

Background And Objective: Studies about maxillary sinuses of cleft lip-palate patients have increased since sinusitis is commonly observed in these patients. It is evident that maxillary sinus will be morphologically affected in these patients. And anatomic differences may be a cause or at least a contributor of sinusitis.

Introduction: The aims of this study were to quantitatively evaluate the changes in arch widths and buccolingual inclinations of the posterior teeth after asymmetric rapid maxillary expansion (ARME) and to compare the measurements between the crossbite and the noncrossbite sides with cone-beam computed tomography (CBCT).
Methods: From our clinic archives, we selected the CBCT records of 30 patients with unilateral skeletal crossbite (13 boys, 14.2 ± 1.
Objectives: The aim was to investigate mandibular third molar (3M)'s maturation in the crossbite and normal sides by two- and three-dimensional analyses using cone beam computed tomography (CBCT).
Materials And Methods: A retrospective study was performed using CBCT of 25 patients (16 females and 9 males; mean age: 16.8 ± 2.
Purpose: The purpose of this study was to evaluate the prevalence of various congenital dental anomalies in the permanent dentition of Turkish children with Down syndrome.
Methods: The sample consisted of 216 diagnostic records of children diagnosed with Down syndrome. All subjects had a clinical examination as well as radiographs and photographs taken.
Introduction: Patients affected by cleft lip and palate often have complaints of snoring and respiratory difficulties during sleep. The purposes of this study were to evaluate nasopharyngeal, oropharyngeal, and total airway volumes of patients affected by unilateral cleft lip and palate and to compare them with a well-matched control group without unilateral cleft lip and palate using cone-beam computed tomography.
Methods: The study sample consisted of 60 patients (26 girls, 34 boys) divided into 2 groups: unilateral cleft lip and palate (20 boys, 10 girls; 8 right sided, 22 left sided; mean age, 14.
The main purpose of this paper is to evaluate q-Sumudu transforms of a product of q-Bessel functions. Interesting special cases of theorems are also discussed. Further, the results proved in this paper may find certain applications of q-Sumudu transforms to the solutions of the q-integrodifferential equations involving q-Bessel functions.

Introduction: The aims of this study were to evaluate condylar and ramal mandibular vertical asymmetry in a patient group affected by unilateral (UCLP) and bilateral (BCLP) cleft lip and palate, and to compare the findings with a well-matched control group with normal occlusion.
Methods: The study groups included 20 UCLP patients (12 male, 8 female), 21 BCLP patients (12 male, 9 female), and a control group of 21 subjects with normal occlusion (10 male, 11 female). Measurements of condylar, ramal, and condylar plus ramal heights and asymmetry indexes were examined on cone-beam computed tomography images.

A single median maxillary central incisor (SMMCI) is a rare dental anomaly that may occur alone or be associated with growth deficiency or other systemic abnormalities. The best known association is with holoprosencephaly (HPE). HPE is a complex brain malformation that affects both the forebrain and the face.
