The purpose of this study is to investigate fluoride release in the oral cavity from polymer adhesive tape which is NaF coated PVA. 45 healthy adults were divided into 3 groups by the type of topical fluoride applied: 60seconds taste
APF gel (group 1), FluoroDose
varnish (group 2) and NaF-PVA (group 3). Topical fluoride was applied to the facial surface of maxillary 12 teeth and unstimulated whole saliva was collected to measure fluoride release after 1, 3, 6, 12, 24, and 48 hours. Fluoride-sensitive electrode was used for measuring the fluoride concentration in the saliva samples. All three groups showed significantly higher value for fluoride concentration than the baseline after 1 and 3 hours (p < 0.05). After 6 hours, group 3 showed significantly higher fluoride concentration than the baseline (p < 0.05) and also showed significantly higher value for fluoride concentration than group 1 and group 2. Between group 1 and group 2, however, there was no significant difference statistically with respect to fluoride concentration value (p > 0.05).

The purpose of this study was to investigate the mesiodistal widths at the cervical level of primary second molars in Korean children, and to compare them with commercial rubber dam clamps commonly used in pediatric dentistry. Dental casts of 115 primary and mixed dentition children were studied. Cervical mesiodistal width (C-MD) was measured at the clinical cervical level of each primary second molar from buccal and lingual sides using a digital caliper (Absolute, Mitutoyo, Kawasaki, Japan). The data were compared with mesiodistal widths of rubber dam clamps #203/204, #10/11, and #205 (Dentech, Japan). C-MDs of primary mandibular second molars were larger than those of primary maxillary second molars, and C-MDs at buccal sides were larger than those of lingual sides. All C-MDs showed statistically significant discrepancies to corresponding widths on clamps (p < 0.05). However the amount of discrepancy was mild in maxillary teeth, while up to 1 mm of discrepancy was shown in mandibular teeth. In conclusion, C-MDs measured in this study imply a relatively fair fit of #10/#11 or #203/#204 clamps on primary maxillary second molars, while suggesting our need for a better clamp with proper size for primary mandibular second molars.
THREE-DIMENSIONAL EVALUATION OF IMPACTED MAXILLARY CANINES USING CONE BEAM COMPUTED TOMOGRAPHY AND PANORAMIC RADIOGRAPHS

Normal eruption of the canine is important for the transition to the permanent dentition. Etiologies, including premature loss or delayed retention of deciduous teeth, neoplasm and abnormality of lateral incisor can cause impaction of the maxillary canine. Untreated canine impaction can result in malocclusion, cyst formation and obstacles in orthodontic treatment. The aim of this study is to evaluate location of the impacted maxillary canine and to identify correlation between location and management of the impaction including complications. Using panoramic radiographs and CBCT scan, images of 89 children diagnosed with impaction of the maxillary canine, location of impacted canines was evaluated. The choice of treatment and complications were investigated to identify correlation. Results show that the most commonly impacted location of the maxillary canine was in the mid-alveolar area, followed by buccal side and palatal side. Orthodontic traction was selected more frequently than the other treatments. As complications, displacement of adjacent tooth was occurred most frequently. Buccally impacted canines showed increased tendency towards displacement. The more buccally the canine was impacted, the less orthodontic traction was chosen as the treatment. The canine impacted mesially to the central incisor showed increased tendency to occur root resorption. Therefore, early diagnosis by periodic examination, appropriate treatment and intervention is required.
VITAL PULP THERAPY USING PLATELET-RICH FIBRIN IN AN IMMATURE PERMANENT TOOTH : CASE REPORTS
Lee, Ka-Young ; Lee, Sang-Ho ; Lee, Nan-Young ;

Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. Pulpotomy is a vital pulp therapy in which a portion of the coronal pulp tissue is surgically removed, and the remaining radicular tissue is covered with suitable material that protects the pulp from further injury and permits and promotes healing. It is important to develop biocompatible treatment directed at maintaining pulp vitality and increasing tooth longevity. Platelet-rich fibrin (PRF) has been referred to as a second-generation platelet concentrate. Two clinical cases in which PRF was applied as a medicament after pulpotomy of an immature permanent tooth are presented. After isolation, caries removal and pulpotomy with PRF was performed. A layer of mineral trioxide aggregate (MTA) was placed over the PRF, and the final restoration was performed. Postoperatively, the patient had no pain or discomfort, and follow-up radiographs revealed normal periodontal ligament space and trabecular bone pattern.
CONTINUED ROOT DEVELOPMENT AFTER AVULSION OF IMMATURE TEETH

Traumatic injuries to immature permanent teeth are common and the results can be destructive. Although Hertwig's epithelial root sheath is usually sensitive to trauma, it may resist damage from trauma thereby retaining its vitality and continuing to calcify a root under favorable conditions. This case report describes two cases of trauma to immature permanent incisors. The first case presents an avulsed maxillary central incisor which has been replanted. The other case shows completely avulsed mandibular central incisors which have not been replanted. However, both cases subsequently show continued growing roots separated from the main roots. This report highlights the ability of the immature pulp tissue to continue to form dentin and the robustness of Hertwig's epithelial root sheath to initiate root development despite a traumatic injury.
ORAL FINDINGS AND TREATMENT OF A PATIENT WITH CYCLIC NEUTROPENIA

Cyclic neutropenia is a hematologic disorder characterized by a marked decrease in the number of circulating neutrophils occurring at regular intervals and after this period, the level of neutrophils usually recovers to a normal range. The clinical symptoms of cyclic neutropenia include fever, malaise, headaches and oral findings associated with painful soft tissue ulceration where lips, tongue and gingiva are typically involved. A 4 year 1 month old boy was presented to the hospital. His chief complaint was mobility of his teeth and swollen gums. The patient had suffered from cyclic neutropenia. Clinical examination revealed evident decay on all primary teeth except for the mandibular anterior teeth and localized alveolar bone loss around mandibullar right and left first primary molars which have mobility was notable. The patient was diagnosed with multiple dental caries, gingivitis and localized periodontitis associated with cyclic neutropenia and treated based on it. The dental treatment, including regular tooth care and appropriate treatment of dental caries or gingivitis, is essential for patients suffering cyclic neutropenia. Especially, proper care at an early stage is needed for young patients to minimize the unwanted consequences for permanent teeth development.
