Introduction: Caries prevention through diet control can be achieved clinically by use of the cariogenic potentiality for a range of food commonly eaten by Koreans. Material & methods: The cariogenic potentiality index of each food can be calculated with the sugar contents and the viscosity of each food applying the regression analysis on the variables. 278 favorite foods for Korean were examined. Result 1. The formula of CPI is as below Cariogenic potentiality index (CPI) = 2.581343*sugar contents+0.598324*viscosity 2. The average CPI of the fruits, vegetable are 9.07~9.62 minutes. But the average CPI of the carbohydrate food is 15.21~19.60 minutes. Conclusion: Using the cariogenic potentiality indices, we will be able to determine an individual patients' average oral status for caries experience in the future. In addition, diet control by use of the cariogenic potentiality index and the analysis for each nutrient is considered as useful clinically for diet control in preventive dentistry .
Purpose: Antral pseudocyst is a common benign lesion that exists in the maxillary sinus. Because of this possible complication, controversy remains with respect to sinus floor elevation operations. The purpose of this study was to analyze the antral pseudocyst related to maxillary sinus augmentation. Patients and Methods: The radiographs of 268 patients who visited Chosun University Dental Hospital from 2008 to 2010 and underwent the maxillary bone grafting procedure were examined. Results: Of the 268 patients who underwent the maxillary bone grafting procedure, 5 patients (1.86%) were diagnosed with antral pseudocysts. In all cases, maxillary sinus floor elevation was performed without aspiration, biopsy or extraction of the antral pseudocyst. Conclusion: Antral pseudocysts are not considered a contraindication for maxillary sinus bone grafting procedure.
Dentin bonding systems are unique dental materials which are rapidly evolute and essential materials for bonding of restorative materials to dentin. Now, 4th generation, 5th generation, 6th generation and 7th generation of dentin bonding systems are used in clinic. We investigated the frequency, motivation of choosing dentin bonding systems and satisfaction of them by survey in 2014. 5th generation of dentin bonding systems are mostly used in Korea and young dentist have tendency to choose newly developed dentin bonding systems.
The maxillofacial soft tissue trauma is one of the major causes to visit the emergency room. For the past few decades, however, the basic concept of the repairing the soft tissue wound have not been changed. Therefore, it could be worthwhile to remind the fundamental concepts and practical information belong to the soft tissue injury management. Among the many types of soft tissue trauma, laceration wound which is most frequently met in the clinic will be discussed in this review.
Orbital fractures have a significant portion in facial bone trauma. The important thing in treatment of orbital fractures is variable depending on the patient. Reconstruction of orbital wall demands an understanding of the anatomy and function of the orbit, including the orbital tissues, and the approacheds, materials, and methods available.
Panfacial fracture is extremely difficult to manage facial injuries but concomitant injuries and severe complications including facial esthetic and functional problems can make it harder. Thorough evaluation and closed co-work with other specialists is needed when reduction and fixation cannot be achieved quickly. Emergency bony support and soft tissue key suture provide the patients with airway integrity, hard and soft tissue vitality. A systemic treatment plan must be made by 3D CT image. This plan include airway management for surgery, sequence of reduction and fixation, approach method, soft tissue resuspension and reconstruction of lost tissue like inferior orbital wall, zygomaic buttress and soft tissue. From known to unknown structures, accurate reduction and fixation will provide proper occlusion, facial projection, width, hight and function. Consideration about facial retaining ligaments must be given to prevent soft tissue sagging.
