| 内容記述 | Using 585 X-ray films taken for the treatment in the hospital of Matsumoto Dental College during one year between May, 1978 and April, 1979, caries regions of mandibular second and third molars were investigated with the relation to the plantations of the third molars. 1) The plantation of mandibular third molars against the second molars can be classified six types, disto-angular type, vertical type, slightly mesio-angular type, intense mesio-angular type, horizontal type and impacted type. 2) As the result of this investigation, vertical type was most common, 37%, horizontal type 21%, intense mesio-angular type 16%, slightly mesio-angular type 8%. Impacted type was relatively common, 11%, conversely disto-angular type was rare, 7%. 3) Intense mesio-angular type was more common in the male than in the female and horizontal type was similarly, conversely vertical type was more common in the female. 4) The frequency of the caries from distal contact point on mandibular second molars was 40% in the C type, i. e. mandibular third molars erupted completely and slightly mesio-angular. And in the D type, i. e. mandibular third molars erupted incompletely and intense mesio-angular, 50%. These showed very high rate. 5) Frequency of the caries from mesial contact point on mandibular third molars was 48% in the C type, and 38% in the D type. These showed very high rate. 6) No relations of caries region of mandibular second and third molar were observed in the A type and B type. In the C type, distal surface caries on mandibular second molars and mesial surface caries, mesio-occlusal surface caries, mesio-disto-occlusal surface caries on third molars were often seen. The D type showed distal surface caries on mandibular second molars and occlusal surface caries on third molars. In the E type occulusal surface caries and disto-occlusal surface caries on mandibular third molars were also observed. | |||||||
