Prevalence of selected developmental dental anomalies in children, in Sri Lanka.

Dental anomalies of school children in Kandy, Sri Lanka are described in this report. The sample studied consisted of 683 children, between 13-16 years old, living in a low-fluoride area. In this sample, 42 percent had at least one anomaly, the most prevalent being enamel defects. Anomalies related to hypodontia and tooth form were to a large extent similar to the reports from the Western Hemisphere. Tetracycline staining of teeth found in 13 percent of the sample, however, raises concern. Hypoplasias, perhaps due to local infections or systemic disturbances during childhood illnesses, were expected to be higher than other published reports.

[Cleidocranial dysplasia--histological findings in the dental cementum].

Up to now only very few reports on histological studies of teeth in cleidocranial dysplasia have been published. We are presenting a 12-year old boy with this syndrome. Seven of his teeth were studied microscopically. The most relevant results are as follows: acellular cementum in all teeth, almost complete missing of cellular cementum, normal intermediate cementum. The pathogenesis of the retarded eruption of teeth in this disorder is explained as a result of eburnation of the alveolar bone as well as fibrosis of the gingiva. The therapy of choice in order to stimulate eruption is a rigid orthodontic treatment of the impacted teeth using fixed appliances.

Space control in the primary and mixed dentitions.

Space control has been distinguished from space maintenance. The difference is not a semantic one. Space control calls upon the dentist to apply his knowledge of occlusal development to the patient's condition. It infers assessment and re-evaluation. Space maintenance, unfortunately, sometimes becomes a routine or mechanical placement of appliances. This article has reviewed some of the variables to be considered when effecting space control: the factors that dictate appliance selection and some of the more common appliances used for space control today. No formula has been recommended for the application of appliances. Rather, the dentist has been urged to review the variables and re-evaluate his decisions according to the dynamic development of the patient's dentition.

Dens evaginatus involving a supernumerary (mesiodens) tooth.

The presence of dens evaginatus has not been reported previously in the Indian race. The condition affects the premolars most commonly, and is rarely reported in molars, canines, or incisors. The involvement of a supernumerary (mesiodens) tooth with a traumatic aetiology is a rare finding. The treatment included the extraction of the involved tooth for functional and aesthetic reasons.

[Interferences with the development of the jaws and teeth in mixed dentition].

On the basis of results from animal experiments, the authors emphasize a series of factors interfering considerably with tooth eruption. It is dealt with tooth eruption disorders and dental malformations due to premature loss of teeth, fused deciduous teeth, certain dystrophies, submersion of deciduous teeth, dysembryoplasias, and rickets.
