The purposes of this study were to compare the sensitivities of two tests, QST(quantitative sensory test)and PPG(photoplethysmography) in normal adults. We evaluated the sensory thresholds of QST and PPG and diabetes mellitus test in 17 normal adults. The finding of this study can be summarized as follow :The diagnostic sensitivities of QST was similar to PPG. There is a direct correlation between the amount of Blood sugar and parasympathetic nerve in ANS. Concluded that the QST might be complement to NCS for early of diabetic polyneuropathy. A new diagnostic approach, QST was introduced and exploited for diagnosis. This study provides support for PPG performed a ANS analysis.

This study was designed to investigate the difference of teeth and craniofacial complex between normal occlusion and Angle's Class II, div. 1 malocclusion in Korean children. The sample was divided into 2 groups, the 66 subjects with normal occlusion and 96 subjects with Angle's Class II, div. 1 malocclusion in both sexes. The results obtained were as follows: 1. No significant differences were observed in ant. cranial base length & cranial flexure (saddle) angle) between normal occlusion & Angle's Class II, div. 1 malocclusion group, but posterior cranial base length of Class II, div. 1 malocclusion group was larger than that of normal occlusion group. 2. No significant difference was observed in the anteroposterior position of Maxilla to cranial base between two groups, but mandibular position in Class II, Div. 1 malocclusion was posterior and interior to that of normal occlusion. 3. The length of maxilla (ANS-PSN) was larger in Class II, div. 1 malocclusion than normal occlusion. The length of mandibular body (Go-Me) was nor different between Class II, div. 1 malocclusion and normal occlusion. 4. Maxillary incisor position of Class II, div. 1 malocclusion to cranial base was more protrusive than that of normal occlusion, but there was no difference in mandibular incisor position between two groups.
