[The clinico-radiological assessment of dental anomalies with real and apparent numerical defects].

Dental anomalies involving real shortfall in the number of teeth (agenesis) or apparent deficiency (impaction) have been studied in a population sample including 700 national servicemen aged between 19 and 26, in the period April-August 1989. The study was carried out by means of careful objective examination and the systematic performance of orthopantomography showed that 5.14% of the population examined is affected by dental agenesis. The tooth most often involved in agenesis is the lateral maxillary incisor followed by the third mandibular molar, the second mandibular premolar and the second maxillary premolar. As regards apparent agenesis, the upper and lower wisdom teeth were the most frequently involved in physiological or pathological bone impaction (this event occurs in almost 50% of third molars). The maxillary cuspid is also impacted with some frequency. The data obtained were compared with those in the world literature.

[The rate of the eruption of human teeth. A review].

The speed that a tooth bud or growing tooth attains on its way to the level of occlusion merits biological and clinical interest. In this work, all data available in the literature related to the eruptive movement of the various permanent teeth in man, both prior and after their clinical emergence in the oral cavity, have been gathered and recalculated in rates of movement per day. For comparative purposes, the rates of migration of nonerupted teeth, of bone resorption and bone apposition, as well as the rate of elongation of growing tooth roots were also collected from the literature. The standardized data (rates in micron/day) revealed the intraosseous movements of tooth buds and growing teeth are dependent and limited in speed by the rates of bone resorption and bone apposition. The extra-alveolar movement of clinically visible tooth crowns on their course of prefunctional eruption occurs at a much higher speed which probably results from a combination of the rate of bone apposition in the apical region and the rate of root elongation. These findings are discussed in connection with our present knowledge on the mechanisms of tooth eruption.

Occlusal disturbances resulting from neglected submerged primary molars.

Several studies indicated that submerged teeth have no long-term effect on occlusal development. Individual cases, however, may present extreme complications. Lack of close supervision, in such instances, may lead to serious consequences. Two cases of negligence (one on the parents' part and the other a consequence of the dentist's carelessness) are presented. The need for a close follow-up of submerged teeth is emphasized, and a rigid periodical recall schedule is suggested.

[Surgical disimpaction and orthodontic repositioning of a retained upper central incisor in the maxilla].

Surgical disinclusion and orthodontic repositioning of superior central incisor retained in the maxillary. A clinical case of inclusion of a permanent central incisor in a nine-year-old patient subjected to combined surgical/orthodontic treatment is reported, the purpose being to demonstrate and confirm the relative simplicity and indisputed advisability of conservative treatment in the case of young patients suffering from dental retention.

[Classification and etiopathogenesis of upper canine impaction].

Classification and aetiopathogenesis of upper canine inclusion. The possible causes of upper canine inclusions are reviewed. After a detailed description of the factors that generally contribute to determining inclusions, it is stressed that correct aetiopathogenetic classification of this pathology can contribute to making the complex protocol for its treatment easier.

[Localization of retained teeth in radiogram].

The purpose of the study was evaluation of various possibilities of localization of retained teeth. The study was carried out on 86 patients referred to the Department of Conservative Stomatology, Institute of Stomatology Medical Academy in Lublin. Retained teeth were discovered in them accidentally or in examinations for various symptoms. On the basis of history data, clinical examination and radiological findings the following localization of retained teeth was recognized: 1) lateral or anterior part of the mandible, 2) lateral or anterior part of the maxilla, 3) maxillary sinus or its vicinity, 4) ascending ramus or condular process, 5) vicinity of the lower orbital margin and piriform fossa.

[Study on the content of certain elements in retained teeth].

The content of calcium, phosphorus.potassium and zinc was determined in 21 retained canine teeth and in a control group of canine teeth erupted completely. In the measurement the method of X-ray fluorescence was used. The obtained results were subjected to statistical analysis. In relation to control canines the retained teeth contained significantly more calcium and phosphorus and significantly less potassium. No significant differences were found in zinc content.

[Tooth retention in the anterior region].

Bibliography was researched in pursuit of an improved classification of retained canine teeth that may, ideally, prove to be simpler, easy to apply in any individual case, and uncomplicated to remember. Desirably, such classification would allow establishing the location of each retention in the maxilla, mandible, or both, and its relationship with adjacent structures. Additionally, a proposal was put forth for a retained canine teeth classification that may clearly and simply outline the retention, be easily understood and remembered, and may also apply to retained dentary organs with some similarity to canines as to their shape and root number.

[A case of supernumerary teeth in the fissure of bilateral complete cleft of the lip, alveolar process and palate].

A case is described of 2 supernumerary teeth in a male patient aged 18 years with complete bilateral cleft of the lip, alveolar process and palate. These supernumerary teeth were situated symmetrically in the vicinity of the lateral incisors. They were well developed, atypical, one was partly retained, with indentations in the crown, the other was completely retained and showed enamel hypoplasia.
