[Studies on tooth migration in animal experiments].

The migration of the germ of the 2nd lower molars after the extraction of all adjacent teeth in comparison to the health side was investigated in Vietnamese hanging belly pigs. The animals were killed in seven age groups so that the results could be evaluated in dependence upon the time. The biometric results reveal migratory phenomena similar to those described for humans after tooth extraction.

Tooth migration subsequent to surgical treatment of mandibular protrusion.

Changes of the dental arch dimensions after surgical correction of mandibular prognathism are very limited. Except for a decrease of the mandibular intercanine width, an increase of the mandibular intermolar width, and a decrease of the maxillary dental arch length, the dentition remains remarkably stable. It thus seems that the changed function postoperatively does not result in great changes in the position of the teeth within the jaws.

Gingival overgrowth and dental alveolar alterations: possible mechanisms of cyclosporin-induced tooth migration. An experimental study in the rat.

The inter-incisal distance and dimension of the interdental papilla between the mandibular incisors were examined in cyclosporin A (CSA) fed rats over 6 weeks. Rats in the test group received CSA daily in mineral oil by gastric feeding (30 mg/kg body weight); the control group received mineral oil only. The inter-incisal distance and gingival dimensions, including bucco-lingual width and vertical height, were assessed biweekly from alginate impressed stone models. Animals were sacrificed at the end of the study and tissue sections were obtained from the anterior region of the mandible for histopathological evaluation. Both the inter-incisal distance and the dimension of the interdental papilla were significantly greater in CSA-exposed animals compared to control. The significant alteration appeared earlier in the papillary dimensions than that in the interdental distance. Particular histopathological alterations of the soft and hard tissues of the periodontium were observed in CSA-exposed animals. Within limitations of the study, we suggest that the CSA-induced gingival overgrowth may offer an active force contributing to observed tooth movement, however, remarkable alveolar remodeling should be considered as an undetermined factor for the movement.

Biometric analysis of tooth migration after approximal contact removal in the rat.

Nineteen 8-week-old female Sprague-Dawley rats were used to observe macroscopically the direction of tooth movements following removal of approximal contacts. In 10 rats, under anaesthesia, approximal contact between the second and third right maxillary molars (M2-M3) was removed by grinding. These animals and a control group of nine rats were housed with normal diet and water ad libitum for 7 weeks. After killing, the skulls of all animals were removed, dried, and fixed in a standardized position on a Horsley-Clarke type stereotaxic frame. Using a micromanipulator graduated to 1/100 mm and mobile in three orthogonal directions, distances between the teeth (M1 or M3) and some bone structures that served as landmarks were measured. These measurements showed the direction of tooth movements in the experimental approximal space. After statistical analysis of the data, the results showed that the approximal space between M2 and M3 was closed by both a distal drift of M1-M2 and a mesial migration of M3. It was concluded that, in the rat, a mesial drift exists that can be induced by the loss of approximal contact. This movement is distinct from the distal physiological dental migration classically described in histological studies.

[Relationship between age and clinical symptoms of periodontal disease].

The purpose of this study was to evaluate the relationship between age and clinical symptoms of periodontal disease as they were evaluated by themselves when they were presented for periodontal treatment in the private clinics of the authors during a period of ten years. A questionnaire was designed for this reason which included questions related to gingival bleeding, gingival enlargement, tooth migration and tooth mobility. 230 questionnaires were evaluated from a total of 1175 consisting a representative sample. The answers were evaluated in relation to the age of the patient. The results showed that a positive and significant relationship exists between the age and gingival bleeding, gingival enlargement, tooth migration and tooth mobility. The patients are becoming aware of two, three or four symptoms of periodontal disease during the fifth decade of life (40-49 years old). The symptoms that are mainly appearing in the groups of patients below forty are the gingival bleeding and the gingival enlargement. After the age of forty the main symptoms are tooth mobility and tooth migration. In conclusion, the results of this study indicate: a) that age could be a parameter that can influence the symptoms of periodontal disease, and b) that the bigest percentage of patients are becoming aware of the presence of symptoms of periodontal disease in a later age and when the disease has progress remarkably.
