초록

The menta1 foramen is located between the first and second premolar regions. The direction of mental cana1 is cornmonly described as being outward, backward, upward from its origin at the mandibular canal‘ The mental nerve is a terrninal branch of the inferior alveolar nerve that passes through the menta1 foramen, supplying sensory innervation to the lower lip, bucca1 vestibule, and gingiva of the mandibular premolar regions. The purpose of this study was to investigate the position of the mentaJ foramen and the length and the direction of the mentaJ canal in Korean. 1n this study, 41 aduJt dry mandibles were investigated independentJy by four observers. The position of the mental foramen and the distance from the mandibular inferior border were measured using conventionaJ nder. The Jength of the menta1 canal was measured directJy using periodontaJ probe. The horizontal and vertical angJes of the mental cana1 were measured by protractor. The student’s T - test was carried out to assess right and Jeft side difference.
The results were as foJJows: 1. The majority of the mental foramen were Jocated below the second premolar' (66.1%), and then between the first and second premoJars(27.4%)‘ 2. The distance between the mental foramen and the inferior border of mandible was 14 .4l:!:1. 47mm(mean 土SD) in right side and 14.36:!:l.42mm in left side(P>O.05) 3. The Jength of the mental canal was 7.8l:!:1.12mm in right side and 7.95:t1.ODmm in Jeft side(P>O.05).
4. The horizonta1 angle of the mentaJ canal was 24.26土5.470 in right side and 24.8l:!:4.7870 in Jeft side(P>O‘ 05) 5‘ The vertical angle of the mental canal was 27.34土4.550 in right side and 28.79:t4.11 0 in left side(P>O.051.
6. The length of anterior Joop of the mental canal was 7.1l:!:1.l5mm in right side and 7.07:tO.99mm in Jeft side(P>O.05) These results suggest that dentist have to consider the mental foramen and menta1 canal when attempting to achieve regiona1 anesthesia, periodontal surgery, and endosseous implants
