For the purpose of evaluating the appropriateness of AP-PCR as a facile, rapid and reproducible method for genotyping Streptococcus mutans, and selecting the discriminant primer for it, a DNA fingerprinting was performed on the microorganisms isolated from caries-free children and children with rampant caries, respectively. In the course of selecting appropriate primer for S. mutans genotyping, we chose S2 primer from 6 different primers which shows highest resolution on the agarose gel as well. Nineteen kinds of fingerprint patterns were observed in caries-free children and children with rampant caries which were produced by combination of 7 different fragments. Interestingly, the number of types observed in caries-free children was greater than that in children with rampant caries. And we observed Type 2 was predominant in children with rampant caries (about 80%) and relatively even distribution of each types in caries-free children. Furthermore, it was appeared that the major types in normal control were not or rarely found in children with rampant caries. In conclusion, we could establish simple, rapid and highly reproducible AP-PCR method for genotyping S. mutans. We also found differences in distribution of S. mutans between normal and patient, which suggested that cariogenicity is also dependent on qualitative aspects which is caused by the difference in genotypes of S. mutans in oral cavity.

As a part of host factors of dental caries, saliva has been well known for its important role in relation to dental caries. The studies on its physical and chemical characteristics on development and progress of dental caries has been conducted. Recently, various comparisons between saliva of caries-susceptable individuals and caries-free individuals has been done and the efforts to understand the mechanisms of salivary intervention of development and progress of dental caries is actively in progress. In this study, 15 children with rampant dental caries and 15 caries free children without any systemic diseases from the ages of 2 to 5 were chosen for the experiment and the whole saliva and parotid saliva from each individuals were collected and protein compositions were compared using polyacrylamide gel electrophoresis (PAGE). As results of this study, in parotid saliva, there was no difference in protein compositions between the rampant dental caries and the caries free children. While electrophoresis was done with the whole saliva, protein with 120 KDa was found in children with rampant dental caries. However, this protein was not found or unclear, if any for the caries free group. (Exceptionally, clear protein band was present for one person.) Protein compositions of whole saliva of rampant dental caries group was compared before and after the caries control and thick and clear protein bands of about 120 KDa were found in both cases. Protein compostions of caries free children and adults were identical. Quantitative analysis of protein was done for the rampant dental caries group and the control group and no significant difference was found. Taken all together, protein with molecular weight of 120 KDa, found in rampant dental caries group, was still present when the treatment for the dental caries was done so it can be assumed that this protein has no interrelation with the presence of active carious lesions during saliva collecting. It can also be presumed that this specific salivary protein with the molecular weight of 120 KDa found in rampant dental caries group has effect on development and progress of dental caries. Identification on this protein with the molecular-weight of 120 KDa and the role of this protein against dental caries remain to be solved.

Two cases of rampant dental caries patients, 5 year old and 3 year old male, were treated; and got following results: 1) Early treatment of rampant dentral caries is emphasized to obtain favorable treatment results. 2) Premedication prior to treatment is an important factor due to the long operative procedures which may elicit the child's phychological trauma. 3) The full cast gold crown restoration for rampant dental caries in primary dentition indicated because of its precise work for maintaining normal occlusion and gingiva.

The purpose of study was to test the hypothesis that preschool children who experienced nursing caries have high dft index and caries activity in primary dentition. One thousand and seventy-five preschool children from 4 to 6 years old were examined for their caries experience and salivary invertase activity by Resazurin Disc Test. Nursing caries group was identified by the criteria of having more decayed and filled teeth among the upper incisors than among the upper molars. The prevalence of nursing caries was 15.8%. The dft index of nursing caries group was significantly higher than that of the other groups except the rampant caries group(P<0.01). The Resazurin Disc Test score of nursing caries group was significantly higher than that of the other groups(P<0.01) and there was no difference between nursing caries group and rampant caries group. Therefore, it is recommended that children who experienced nursing caries should be incorporated in the caries prevention program through the primary and mixed dentition.

A 12 years old patient having rampant dental caries on permanent dentition has been treated under operative procedures. In addition to this operative treatment the nutritional survey and the caries activity was checked, and performed the oral hygiene instruction to the patient. As the consequences of above procedures the following results were obtained: 1. The familial history and eating habits checkings were helpful for better dental health guide and caries control. 2. The restriction of mono & disaccharide intake and topical application of 8% stannous fluoride at least two times revealed excellent control effect for recurrent dental caries.

The purpose of this study was to investigate the prevalence rate of the nursing caries in preschool children by retrospective epidemiological survey. 500 preschool children in Iksan city were examined for their dental caries experience (dt, mt, ft). Subjects were divided stepwise by the pattern of caries experience: Group 1-no caries, Group 2-no caries in the upper arch, Group 3-no caries among the upper incisors, Group 4-dmft in the lower arch $\geq$ mft in the upper arch, Group 5-dmft among the upper molars > dmft among the upper incisors, Group 6-dmft among the upper molars < dmft among the upper incisors+caries among the lower incisors, and Group 7-the rest. Groups 6 was regarded as the group which had experienced rampant caries, and the Group 7 was regarded as the group which had the typical pattern of nursing caries. The prevalence rate of nursing caries (Group 7) was 16.0%.

Children who have severely destructive anterior primary dentition, as in nursing-bottle caries, in trauma, in rampant caries and in developmental defects, present the dentist with one of the most perplexing situations in dentistry. Especially, children with managed behavor difficultly is very severly situations. This paper reported a new technique for the utilization of resin post and strip crown to indirect methods on severely destructive primary anterior teeth. We name it "indirect short resin post crown" in this paper. Indirect technique be considered to be a simple, a retentive, intensive, color-stable and esthetic restoration.
