Objective: To establish the chronology and sequence of eruption of the permanent teeth in subjects with complete unilateral cleft lip and palate.
Design: Cross-sectional. Data on children presenting complete cleft lip and palate were evaluated.
Setting: The study was carried out at the Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, São Paulo, Brazil.
Sample: The sample comprised 477 patients with complete unilateral cleft lip and palate, aged 5 to 14 years. Of these patients, 166 were girls and 311 were boys.
Results: The girls presented, for all maxillary and mandibular teeth, a smaller mean age of eruption than the boys. The maxillary lateral incisor and cuspid adjacent to the cleft presented significantly higher mean ages of eruption than their homologous teeth on the noncleft side.

Aims And Background: The study of the morphology of soft tissues as well as hard tissues of the orofacial region holds prime importance. A very less information is known about the lips (soft tissues) and maxillo-mandibular arches (hard tissue structures) in primary dentition. Henceforth, there is a need to classify, find the prevalence and correlation of various lip shapes, and arch forms in primary dentition.

Introduction Unilateral cleft lip and palate (UCLP) often leads to maxillary hypoplasia and skeletal Class III malocclusion, with conflicting evidence on mandibular asymmetry. This study evaluated vertical mandibular asymmetry in UCLP patients, comparing them with non-cleft individuals having skeletal Class III and Class I malocclusions. Methods Mandibular asymmetry was evaluated using orthopantomograms (OPGs) from 90 subjects divided into three groups of 30 each: UCLP group, non-cleft skeletal Class III, and non-cleft skeletal Class I.

Aim: To compare three-dimensional (3D) facial morphology of various unilateral cleft subphenotypes at 9-years of age to normative data using a general face template and automatic landmarking. The secondary objective is to compare facial morphology of 9-year-old children with unilateral fusion to differentiation defects.
Methods: 3D facial stereophotogrammetric images of 9-year-old unilateral cleft patients were imported into 3DMedX® for processing.

Cleft lip and palate (CLP) are a usually inherited anomaly described as a gap in the oral cavity's upper lip and/or roof. The etiology of CLP involves both genetic and environmental factors. The current study aimed to examine the genetic basis of nonsyndromic (NS) CLP (NSCL/P) and its association with specific genetic polymorphisms.

Edentulous patients with history of cleft palate and severe maxillary atrophy are challenging patients to rehabilitate through an oral approach. The difficulty of rehabilitating these patients lies in the unusual anatomy they present and the alteration of the vascular supply of local tissues caused by the previous performed surgeries, along with other causes. This report describes the successful dental rehabilitation with zygomatic implants of a patient with complete bilateral cleft palate who was edentulous and had severe maxillary atrophy.
