Abstract：Objective To analyze the differences of interfurca alveolar bone width detected by digital camber layer and spiral CT. Methods The clinical data about 6 subjects who received the detection in our hospital from January 2014 to January 2017 were analyzed,with the interval distance of dental alveolus top being 2. 5mm, 5. 0mm,7. 5mm and 10. 0 mm, which was measured by digital camber layer and spiral CT, respectively. Results There were no significant differences in the data values at 2. 5mm interval distance of dental alveolus top in maxillary first molar and second molar (U6-7), mandibular second premolar and the first molar (L5-6), mandibular first premolar and the second molar (L6-7) between digital camber layer and spiral CT (P>0. 05). There were no significant differences in the data values at 5. 0mm interval distance of dental alveolus top in U6-7,L5-6,L6-7 between digital camber layer and spiral CT (P>0. 05). Moreover there were no significant differences in the data values at 7. 5mm interval distance of dental alveolus top in U5-6,U6-7,L5-6,L6-7 between digital camber layer and spiral CT (P >0. 05). In addition there were no significant differences in the data values at 10. 0mm interval distance of dental alveolus top in U5-6,L5-6 between digital camber layer and spiral CT (P>0. 05). Conclusion Digital camber layer and spiral CT play the same role in measuring the interfurca alveolar bone width between mandibular second premolar and the first molar, as well as between first molar and second molar. But there are some difference in measuring the interfurca alveolar bone width between canine teeth and the first premolar and between the first premolar and the second premolar, therfor, it is necessary to select a reasonable measuring method.
