Cleft lip and palate is the most common malformation in the craniofacial region. The patients with cleft lip and palate have functional problem such as, speech, feeding and respiratory as well as esthetic problem. So, treatment should be done by multidiciplinary team approach. The role of pediatric dentist in the team is advicement for feeding method, guidance of normal growth, caries control and preventive orthodontics. In cleft lip and palate patients, maxillary arch after cheiloplasty is usually collapsed by excessive tension of the scar. This collapse increase the difficulty of later orthodontic treatment. Therefore, the maxillary arch segments should be moved and retaind to normal position as soon as cheiloplasty is done to reduce the need and difficulty of orthodontic treatment. This concept is called by the early orthopedic treatment in cleft lip and palate. Also, this orthopedic appliance works as feeding applince to normal feeding and weight gain We reported two cases of early orthopedic treatment with favorable result in complete bilateral cleft lip and palate patients after cheiloplasty. Patients showed normal weight and their maxillary arch widths were increased.

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.

The purpose of this study was comparision of conventional tomography with reformatted computed tomography for dental implant in locating the mandibular canal. Five dogs were used and after conventional tomographs and reformatted computed tomographs were taken, four dentist traced all films. Mandibles were sectioned with 2mm slice thickness and the sections were then radiographed(contact radiography). Each radiographic image was traced and linear measurements were made from mandibular canal to alveolar crest, buccal cortex, lingual cortex, and inferior border. Following results were acquired : 1. Reformatted computed tomographs were exacter than conventional tomography by alveolar crest to canal length of -0.6mm difference between real values and radiographs. 2. The average measurements of buccal cortex to mandibular canal width and lingual cortex to mandibular canal width of conventional tomographs were exacter than reformatted computed tomographs, but standard deviations were higher than reformatted computed tomographs. 3. Standard deviations of reformatted computed tomographs were lower than conventional tomographs at all comparing sites 4. At reformatted computed tomography 62.5％ of the measurements performed were within. : filmm of the true value, and at conventional tomography 24.1％ were. 5. Mandibular canal invisibiity was 0.8％ at reformatted computed tomography and 9.2％ at conventional tomography. Reformatted computed tomography has been shown to be more useful radiographic technique for assessment of the mandibular canal than conventional tomography.

The purpose of this study is to inquire about the effects of individual tray design and impression method on the border extension and contour of denture. 10 students at the dentistry college who have normal occlusion and symmetric facial form and normal facial muscle activity were selected. The tray was designed three types (large, medium, small tray). After border molding was done by dentist and operator, final impression was taken. The length of impression body and width of border were measured by a vernier caliper on the cast. The obtained results were as follows : 1. As the tray border was shortened, the length of impression body and width of border was short (P<0.01). 2. When the impression was taken with the small tray, the length of impression body was short in passive border molding than active border molding. 3. When the medium tray was used, the width of impression body was short in passive border molding than active border molding.
