The Author measured the position of the mandibular foramen with oblique cephalography in 43 5-aged, and 44 7-aged Korean children. The results of the studies were as follows; 1) The distance from the post. occlusal plane to the mandibular foramen was $3.16{\pm}1.22mm$. in age 5 and $1.86{\pm}1.50mm$. in age7 to the below. 2) The meeting point of the occlusal plane and anterior of the ramus to the mandibular foramen was $16.56{\pm}2.18mm$. in age5 and $16.88{\pm}2.69mm$. in age7. 3) The angulation between the occlusal plane and the line connecting the mandibular foramen and the meeting point of anterior border of the ramus with occlusal plane was $12.70{\pm}4.31^{\circ}$ in age5 and $8.27{\pm}5.36^{\circ}$ in age7 to the below. 4) % depth was $56.93{\pm}5.65%$ in age 5 and $53.20{\pm}7.12%$ in age 7. 5) The price of distance and angulation showed significant results at 0.01 level in KOLMOGOROV-SMIRNOV (TWO-SAMPLE) TEST.

Inferior alveolar nerve block anesthesia is one of the most common procedures in dental clinic. Although it is well known as safe procedure, complications always can be occurred. Ocular complications such as diplopia, loss of vision, opthalmoplegia are very rare, but once it happens, dentist and patient can be embarrassed and rapport will be decreased between them. We experienced one diplopia case after inferior alveolar nerve block anesthesia and treated without any further complication. We report this case and describe the cause, diagnosis, and treatment objectives of diplopia caused by inferior alveolar nerve block anesthesia.

Neurofibromatosis is an autosomal dominant disorder caused by a mutation of a tumor supressor gene on the long arm of chromosome 17. There are two types of neurofibromatosis, and development of neurofibroma is one of clinical diagnostic criteria for neurofibromatosis. The clinical signs of neurofibromatosis include as skin lesions, bone deformities, and tumors involving central nervous system. About 25% of neurofibromatosis involves oral neurofibroma. Radiographically, oral neurofibroma is well-defined unilocular radiolucency, which involves mandibular canal, mandibular foramen and mental foramen. When a lesion is small and approachable, complete resection, including 1cm of marginal connective tissue, is feasible. However, there are studies reporting that the recurrence rate after surgical resection is high and frequent recurrence may even increase the risk of malignant transformation. This case reports a patient with neurofibromatosis type I, accompanying oral neurofibroma, who shows a favorable result after surgical resection of the oral lesion.

The purposes of this study were to evaluate and compare the pulpal anesthesia induced by an inferior alveolar nerve block and that by Gow-Gates technique, and to investigate the relationship between pulpal anesthesia and intraoral soft tissue responses. After one side of mandibule was anesthetized with inferior alveolar nerve block or Gow-Gates technique using 2 % lidocaine with 1 : 100,000 epinephrine in 19 volunteers of ages between 24 and 29 (16 males and 3 females, average age 25.9 yrs.), electric pulp tests were done on the canine teeth of the anesthetized side and contralateral one before, at 1 min, continued at every 5 minutes until 60 min, and every 10 minutes until 100 min after completion of local anesthetic injection. Degree of pulpal anesthesia was classified as anesthetic failure, possible anesthesia and complete anesthesia by the criteria based on the thresholds to electric pulp test of contralateral canine and the currents of the electric pulp tester. Subjective signs on the lower lip and tongue were checked and prick-pin tests were done on the buccal gingiva of the first molar, buccal and lingual gingiva of the canine tooth at 5, 10 and 20 min after the completion of anesthetic injection. Thresholds to electric pulp test, degree of pulpal anesthesia and relationship between the pulpal anesthesia and soft tissue responses were analyzed with SPSS, paired t-test, Wilcoxon matched-pairs signed-ranks test and correlation analysis. The results were as follows : No significant differences were found in the peak thresholds to electric pulp test, in the induction time to it and in the depth of pulpal anesthesia between inferior alveolar nerve block and Gow-Gates technique (p>0.05). There was no significant relationship between pulpal anesthesia and soft tissue responses in both inferior nerve block and Gow-Gates technique.
