The aim of this study was to measure and compare the dimensions of the dental arches on three-dimensional digital study models in children with and without cleft lip and palate before the primary surgery. The sample consisted of 223 digital models of children aged 3-9 months, divided into 5 groups: without craniofacial deformities, unilateral and bilateral incomplete cleft lip and alveolus, uni...

Cleft palate is one of the most common congenital malformations of the oral and maxillofacial region, with an incidence rate of around 0.1%. Early surgical repair is the only method for treatment of a cleft lip and palate. However, because of the use of inhalation anesthesia in children and the physiological characteristics of the cleft palate itself combined with the particularities of cleft p...

Cleft lip and palate are birth defects. Children with cleft lip and palate may have problems with quality of voice. The present study compared the perturbation measures of voice (pre and post surgery) in children with cleft lip and palate. Each group included 15 children age ranged 3 to 12 years. They were asked to phonate vowels /a/, /i/, and /u/. Voice samples were recorded and analyzed by us...

The force for directing palate shelf reorientation appears to be associated with elements of the presumptive hard palate (Brinkley & Vickerman, 1979; Bulleit & Zimmerman, 1985). The palatal elements that mediate this process do not require palate cells to be metabolically active for expression of the force. This contention was demonstrated using an in vitro system that allows substantial reorie...

Cleft lip and cleft palate are one of the most frequent congenital anomalies worldwide. This study was conducted in order to measure the frequency of cleft lip and palate among live births in Akbar Abadi Hospital. This is a descriptive study, dealing with 57526 cases of live birth out of 59477 medical files in Akbar Abadi Hospital from 2004 to 2008. All the collected data were recorded in speci...

AIM To determine the prevalence of type of soft palate in targeted population. MATERIALS AND METHODS Using computer technology in dentistry, intraoral digital scanner, and 3D analysis software tool, study was conducted. 100 patients selected from the outpatient clinics were divided into two groups based on the ages of 20-40 years and 41-60 years with equal ratio of males and females. Each sel...

The aim of the present was to evaluate the effects of DNA methylation and histone acetylation on 2,3,7,8‑tetrachlorodibenzo‑p‑dioxin (TCDD)‑induced cleft palate in fetal mice. Pregnant mice (n=10) were randomly divided into two groups: i) TCDD group, mice were treated with 28 µg/kg TCDD on gestation day (GD) 10 by oral gavage; ii) control group, mice were treated with an equal volume of corn oi...

Compliance with primary surgical treatment in people with cleft lip and palate is a well-known problem, especially in developing countries fraught with poverty and ignorance. Different protocols of treatment exist. In this paper, we retrospectively review a cohort from two centres, with a discussion on the outcome and its implications. The records of all patients with cleft lip and palate seen ...

OBJECTIVE To determine the interrater reliability of drug-induced sleep endoscopy (DISE). DESIGN Prospective cohort; blinded comparison. SETTING Academic referral center. PARTICIPANTS Subjects with obstructive sleep apnea unable to tolerate positive airway pressure therapy. INTERVENTIONS Drug-induced sleep endoscopy was performed with intravenous propofol infusion to achieve sedation, a...

Cleft palate is one of the most common congenital birth defects worldwide. The homeobox (Hox) family of genes are key regulators of embryogenesis, with Hoxa2 having a direct role in secondary palate development. Hoxa2-/- mice exhibit cleft palate; however, the cellular and molecular mechanisms leading to cleft palate in Hoxa2-/- mice is largely unknown. Addressing this issue, we found that Hoxa...
