[Studies on the occurrence of systemic manifestations during first eruption of teeth in children].

The aim of the study was establishing whether systemic symptoms and signs appearing in children during first eruption of teeth are connected with this process, and what is the correlation between the studied features and eruption of individual milk teeth. The study involved 55 generally healthy infants aged 3-4 months, and the observation was continued up to the age of 36 months. The study on the development of teeth was carried out in two Regional Paediatric Dental Clinics in Warsaw, at 6-week intervals in the first year of life, and at 10-week intervals in the 2nd and 3rd years. The systemic symptoms and signs were recorded by mothers, and the obtained data were stored on computer cards. The results were subjected to statistical analysis considering finally these systemic manifestations which were present in at least 25% of children. The manifestations connected with teeth eruption included: profuse salivation, biting of hard, things, restlessness, appetite loss and sleep disturbances. These symptoms were most pronounced at the time of milk incisors eruption, less evident during eruption of first molars, and were absent during eruption of second molars. Canine teeth eruption was connected particularly with restlessness and sleep disturbances. Such signs as raised body temperature, skin changes, gastrointestinal disturbances were only weakly connected with teeth eruption.

[Introduction of a new technique of partial pulp amputation in permanent teeth in children after mechanical injuries. Preliminary communication].

The study material comprised 56 permanent teeth with traumatic pulp exposure complicated in 15 cases by partial tooth luxation in 52 children aged from 7 to 15 years. In each case routine clinical and radiological examinations were done. The time between trauma and procedure ranged from several hours to 70 days. In all teeth partial pulp amputation was done cutting off by the gentle technique a part of the coronal pulp and covering of the remaining pulp with calcium hydroxide, zinc oxide with eugenol or with Dycal, carboxyl cement and permanent filling. The analysis of the studied material showed that the greatest group comprised children aged 8-11 years (40 cases), and fractures of one-half of the crown prevailed (32 cases), point pulp exposure (32 cases), developmental stage Rc and A 1/2 of root (40 cases). The short-lasting follow-up made possible clinical and radiological control of only 39 teeth after 6 months, and 7 teeth after 12 months. After 6 months good results were obtained in 84.6% of cases.

[Radiological estimation of interradicular space of primary molar teeth].

Radiological estimation of interradicular space of primary molar teeth has been performed. Radiograms taken from the department's archives on which primary molar teeth without dental caries were visible have been used for the purposes of the examinations. Roentgenograms had been made for exposition conditions required for endodontic therapy needs. Periodontium, lamina dura of the alveolus, bone texture of the interradicular space and disposition of permanent tooth buds have been estimated according to the radiograms. From the examination results it followed that proper estimation of interradicular space of primary molar teeth according to radiograms made for endodontic therapy needs is not possible. Radiological image of interradicular space of primary molar teeth in various both with reference to bone structure and disposition of permanent tooth buds. In most cases the interradicular space of primary molar teeth demonstrates thin bone structure on radiograms that should be considered to be physiological state when the continuity of lamina dura of the alveolus is preserved.

Caries increment in primary teeth after application of Duraphat fluoride varnish.

In order to evaluate the possible cariostatic effect of a fluoride varnish in the primary dentition, Duraphat varnish was applied twice yearly for 2 years to the teeth of 195 3 1/2-year-old children of both sexes attending nine preparatory schools in the Warsaw area. A control group of 127 children attending nine other preparatory schools was also examined. For each child a dmfs1 index (including "caries without macroscopic defect") and a dmfs2 index ("caries without macroscopic defect" excluded) were determined as well as a dmft1 and a dmft2 index. After 2 years the difference between the test and the control groups regarding the mean dmfs1 and dmft2 index increments was 9.39% (P greater than 0.1) and 24.09% (P less than 0.05), respectively. No significant differences were found, however, concerning the dmft2 and dmfs2 indices, the percentage children with new gingival caries, the number of teeth extracted on account of caries and the number of remaining teeth. A test group of 46 children treated with fluoride varnish in which a complete radiological examination could be carried out before and after the experimental period and which was treated with fluoride varnish was compared with a similar group of 27 children, which was not treated with fluoride varnish. The differences in caries increments were small, less than 15%, and were not significant. Taking into consideration the great variation between the schools it was concluded that the cariostatic effect of Duraphat application twice yearly in the primary dentition of these children was slight.
