Prevalence of dental anomalies in orthodontic patients.

The prevalence of dental anomalies including agenesis, crown shape, tooth position, root shape, and invagination were examined in 111 orthodontic patients; 74.77 per cent of the patients exhibited at least one dental anomaly. Invagination was found to be the most prevalent anomaly, whereas supernumerary teeth and root dilaceration were the least frequent anomalies. Dental invagination and short or blunt roots were significantly more prevalent in females than in males. Implications for orthodontic treatment planning are discussed.

[Tooth and face abnormalities associated with pituitary growth hormone insufficiency].

Dental and facial examination has been performed in sixty-two children with idiopathic or congenital growth hormone deficiency. Fourteen (22%) had a malformation of the upper incisors and/or of the naso-frontal bud or of the eyes, associated in five with a malformation of the brain in the prosencephalon-derived areas. Moreover, fourteen patients had some facial abnormality in an area situated near that derived from the naso-frontal bud. These associations are to be considered as a clinical marker able to call for pituitary investigation in short children. They suggest that some cases of so-called idiopathic hypopituitarism relate in fact to congenital and malformative causes.

Clinical significance of tooth morphology correlated with periodontal disease-I.

Anatomical abnormalities of tooth and root morphology may not only adversely influence the course and management of periodontal disease due to inaccessibility of periodontal instrumentation and oral hygiene efforts, but are also more likely to adversely become high risk areas for retention of dental plaque and calculus. This article reviewed the results of data on the root morphology and comparative literature associated with prevalence, anatomical considerations and clinical significance in the predisposing factors to the periodontal disease. The purpose was to emphasize the importance of understanding the knowledge concerning the variations of tooth and/or root anatomy as a high risk factor for periodontal disease and as a necessary tool for the prognosis, diagnosis and treatment of existing or potential periodontal disease.

[A rare dental abnormality: "the phantom tooth" or "odontodysplasia". Apropos of a case].

"Phantom tooth" or "odontodysplasia" is one of the most unusual and rare of dental abnormalities, being characterised: Clinically, by the topography of the lesions, the involvement of both sets of teeth and abnormalities in the size and form of the teeth which remain unrupted or only partially evolved. Radiologically, by transparency of the teeth to X-rays. Histologically, by disorganisation of the dental structures and a highly characteristic appearance of the enamel and, in particular, dentine. On the basis of one case, the authors review in detail each aspect of these characteristics, paying special attention to histology and the information obtained using the sweep electron microscope.

A natural history of cleidocranial dysplasia.

Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia associated with clavicle hypoplasia and dental abnormalities. The condition is caused by mutations in the CBFA1 gene, a transcription factor that activates osteoblast differentiation. Clinical characteristics associated with CCD have previously been described in case reports and small case series. This study was undertaken to gain a more complete delineation of clinical complications associated with CCD. The study population was composed of 90 CCD individuals and 56 relative controls ascertained from genetic and dental practices in the United States, Canada, Europe, and Australia. A number of previously unrecognized complications were significantly increased including: genua valga, scoliosis, pes planus, sinus infections, upper respiratory complications, recurrent otitis media, and hearing loss. Primary Cesarean section rate was significantly increased compared to relative controls and the general population rate. Finally, dental abnormalities, including supernumerary teeth, failure of exfoliation of the primary dentition, and malocclusion, are serious and complex problems that require intervention. Clinical recommendations based on the results of this study are included.

Dental and craniofacial findings in hypohidrotic ectodermal dysplasia during the primary dentition phase.

A more detailed knowledge of dental and craniofacial features in hypohidrotic ectodermal dysplasia (HED) during childhood is needed in order to include these characteristics among diagnostic criteria. The present study comprised 5 HED children, 4 males and 1 female, during the primary dentition phase. Clinical and radiological dental findings consisted of multiple congenitally missing primary teeth, conoid primary incisors, moderate to severe taurodontic second primary molars. Supernumerary cusps and diastema were found as well. A pattern of symmetry was assessed for hypodontia in the primary dentition. The cephalometric study compared the HED sample to a matched non-syndrome sample and revealed abnormally short maxillary depth (p < 0.05), strongly reduced lower facial height (p < 0.01) and a reduction in facial soft tissue thickness (p < 0.05 - p < 0.01) in HED children. The importance of an early diagnosis and treatment of HED dento-facial malformations so as to improve esthetics and function is stressed.
