The purpose of this study was to evaluate the risk of caries in orthodontic patients before and after active treatment. One hundred and three patients (17 males, 86 females), who were treated in the Obihiro Art orthodontic clinic between 2000 and 2007, participated in the study. The mean age at the first examination was 19.4 years old (range : 8-51 years old). A caries risk test was carried out on all subjects at the first examination and at the end of active treatment. The test consisted of eight items, including volume of saliva secreted over 5 minutes, salivary buffering capacity, number of colonies of Streptococcus mutans, number of colonies of Lactobacillus, eating frequency per day, amount of plaque attached to teeth, daily usage of fluoride toothpaste and/or fluoride gargles and DMFT. From the results of a Wilcoxon signed-rank test, four items (number of colonies of Streptococcus mutans, eating frequency per day, amount of plaque attached to teeth, and daily usage of fluoride toothpaste and/or gargles) at the end of active treatment significantly lowered the risk of caries (P<.01). The other four items showed no difference in caries risk before or after active treatment. From the results of Spearman's rank correlation, three pairs (volume of saliva and salivary buffering capacity, number of Streptococcus mutans and of Lactobacillus, number of Streptococcus mutans and amount of attached plaque) were significantly correlated at both periods. The results of this study strongly suggest that orthodontic treatment simultaneously reduces the caries risk of the patient. This is thought to be due to the morphological and functional improvement of malocclusion, as well as encouragement of the patient's motivation for oral hygiene.

Recently, nosocomial infections of HBV, HCV, and HIV have become a concern, and the prevention of such infections for medical staff and patients based on standard precautions is important. Here the dimensional changes in alginate impressions after immersion in disinfectants and rinsing with water after disinfection was investigated. Experimental condition is as follows : Immersion in disinfectant test 1) Group D: in phtharal for 20 minutes. 2) Group SH: in 0.1% sodium hypochloride solution for 60 minutes. 3) Group W: in distilled water for 60 minutes. Disinfections-rinsing with water test 1) Group D-W : in distilled water for 30 minutes, after immersion in phtharal for 5 minutes. 2) Group SH-W: in distilled water for 30 minutes, after immersion in 0.1% sodium hypochloride solution for 60 minutes. There were 15 test pieces in each condition, and the test pieces were measured with a projector, and dimension change rates were calculated. The data were analyzed by one-way ANOVA and post hoc tests. The results may be summarized as follows. 1. The dimensional changes of Group D and Group SH were smaller than the changes of Group W. 2. The test pieces immersed in distilled water after immersion in disinfectants expanded immediately. 3. Therefore, impressions should be rinsed with water quickly after immersion in disinfectant, then next inject plaster into the impressions soonest possible.

Achondroplasia is an inherited disorder with the characteristic appearance of disproportionate short stature. We examined constitutional symptoms and dental findings in a girl patient, who had diagnosed as achondroplasia. The following results were obtained: 1) The occlusion condition showed an Angle Class III malocclusion and anterior openbite. 2) The abnormality of tooth form, tooth number and development of the tooth could not be observed. 3) Cephalometric analysis showed that short of posterior cranial base and skeletal Class III with severe protrusion of the mandible.
