Dens invaginatus is a developmental anomaly resulting in an infolding of the enamel organ into the dental papilla prior to calcification of the dental tissues. The invagination predisposes the tooth for the development of dental caries. Conventional radiographs do not provide detailed information concerning the three-dimensional image, which would help the clinician in making a confirmatory diagnosis and planning the treatment before undertaking the actual treatment. This report describes a case where Oehlers type II dens invaginatus was diagnosed with the help of spiral computed tomography...

Linear growth failure can be caused by many different genetic abnormalities. In many cases, the genetic defect affects not only the growth plate, causing short stature, but also other organs/tissues causing additional clinical abnormalities. The proband was evaluated at 10 years of age for impaired postnatal linear growth (height 113.3 cm, -4.6 SDS), a bone age that was delayed by 5 years, dysmorphic facies, cognitive impairment, and central nervous system anomalies. His younger brother, presented only with growth failure at 10 months of age...

Dens invaginatus is a developmental malformation, in which there is an infolding of enamel into dentine. These infolds represent stagnation sites for bacteria and can predispose to dental caries. The carious infection can spread via enamel and dentine to contaminate the pulp and cause soft tissue necrosis. The altered and sometimes complex anatomy of affected teeth can make endodontic management challenging. Early diagnosis is therefore essential as prophylactic treatment of the dens can prevent degeneration and pulpal necrosis...

Children with craniofacial anomalies often demonstrate disorders of speech and/or resonance. Anomalies that affect speech and resonance are most commonly caused by clefts of the primary palate and secondary palate. This article discusses how speech-language pathologists evaluate the effects of dental and occlusal anomalies on speech production and the effects of velopharyngeal insufficiency on speech sound production and resonance. How to estimate the size of a velopharyngeal opening based on speech characteristics is illustrated...

BACKGROUND: Apnoea is a breathing disorder marked by the absence of airflow at the nose or mouth. In children, risk factors include adenotonsillar hypertrophy, obesity, neuromuscular disorders and craniofacial anomalies. The most common treatment for obstructive sleep apnoea syndrome (OSAS) in childhood is adeno-tonsillectomy. This approach is limited by its surgical risks, mostly in children with comorbidities and, in some patients, by recurrence that can be associated with craniofacial problems...

OBJECTIVES: The investigation of the record of growth locked in dental enamel provides a unique opportunity to build a comprehensive picture of growth disruption episodes during childhood. This study presents a new methodological basis for the analysis of enamel growth disruptions (enamel hypoplasia) using incremental microstructures of enamel. METHODS: A three-dimensional technique based upon use of an Alicona 3D Infinite Focus imaging microscope and software is used to record developmental features in the enamel of human permanent mandibular lateral incisors of one individual from the Neolithic site of Çatalhöyük (Turkey)...

The roentgenological methods of research take the lead in the diacrisis of dentofacial anomalies, they are of the utmost importance as for the identification of the jaws' growth character, so too for the generation of the treatment planning and of the expected response to the treatment. The type of the jaw growth is identified by the means of a basal angle on the teleroentgenography (TRG). The objective of the research was to develop a rapid test method of identification of the type of growth by means of a basal angle on the orthopantomogram (OPTG)...

Incontinentia pigmenti is a rare genodermatosis in which the skin involvement occurs in all patients. Additionally, other ectodermal tissues may be affected such as the central nervous system, eyes, hair, nails and teeth. The disease has an X-linked dominant inheritance pattern. But in our case, there was a mutation in the body cells due to incontinentia pigmenti. The dermatological findings occur in four successive phases. We report the case of a 10-year-old female presented cutaneous, dental and ophthalmic characteristic with 3 years follow-up...

Congenitally missing teeth are the most commonly seen dental anomalies. Agenesis of the permanent first molar has the least frequency of all the tooth types, and it usually occurs in association with oligodontia or anodontia. Thus, agenesis of the bilateral maxillary first permanent molar is an extremely rare occurrence, and no such case has been reported in ethnic Saudi Arabian population. We hereby report a case of nonsyndromic bilateral congenitally missing maxillary first permanent molar in an eight-year-old Saudi female patient...
