In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear between the monolithic zirconia restoration and the base metal alloy restoration. This phenomenon was confirmed by surface roughness measurement and electron probe micro-analysis.

The conventional approach for replacing missing maxillary lateral incisors dictates the placement of either a conventional porcelain-fused-to-metal (PFM)bridge, resin-bonded fixed partial denture, or single implant prosthesis. However, several appearance-related disadvantages have been reported in the use of a prosthesis which incorporates a metal substructure. To address these limitations, metal -free restorative alternatives have been recently developed to expand the clinical options when fabrication of these prostheses is indicated. This clinical report describes the treatment of patients with a missing maxillary lateral incisor where the dentition was non-invasively restored with resin-bonded fixed partial denture(RBFPD) using In-Ceram and Targis-Vectris system.

Dental clinicians commonly encounter extrusion of the anterior teeth due to localized alveolar bone loss in adult patients with chronic periodontitis. This pathologic migration of the anterior not only may cause loss of functional anterior guidance and continuous periodontal destruction, but also can lead to esthetic disaster. In fact, most frequently reported chief complaint of the patients with extruded anterior teeth is the 'loss of esthetics', not the periodontal problem itself. The utilization of the expertise and skills in the various dental disciplines is thought to be the best treatment modality for the ultimate functional and esthetic attainment. Interdisciplinary therapy, involving periodontics, orthodontics, and restorative dentistry, was performed for the highest levels of patient and provider satisfaction in this case.

To improve esthetics and gain beautiful smile, the maxillary anterior dentition is crucial. Through alteration of height, arrangement or color of the maxillary incisor, we can rehabilitate the esthetic smile. The perception of dental esthetics is highly subjective. Personal perceptions or judgement of dental esthetics is highly related with each individual's experience and social and cultural environment. However, there have been many efforts to establish the criteria for generally accepted esthetic norm, in order to increase the predictability of restorative treatment. For maxillary anterior restoration, not only a single tooth, but also the compositions around tooth such as facial form, lips and gum and their relationships have to be considered to create harmonious smile. It can be determined as esthetic restorations when in consonance with facial form and structures that frame the restorations. In this review article, several guidelines that are generally accepted and useful to assess the esthetics and communicate with patients and technicians will be discussed.

The purpose of this study was to evaluate the changes in the degree of conversion on a composite resin surface following heat treatment and mylar strip finishing. The effects of the time interval between the light-curing and heat-curing process were also evaluated. The composite resin surface which had been covered with a coverglass showed a lower conversion rate than the surface from which a layer of $500{\mu}m$ was ground away. The composite resin surface was definitely affected by oxygen during the heat curing process when it had not been insulated. When the composite resins were heat cured after 3 days of storage following the light curing process, the increased in the degree of conversion through heatcuring was limited.

The final preparation (MAF) size in infected root canals is still controversial. Nonetheless, recent studies demonstrated that larger apical preparation sizes produces a greater reduction in remaining bacteria and dentinal debris as compared to smaller apical preparation sizes. Therefore, clinicians should be practiced with treatment strategies guided by evidence-based information, especially in infected/failed root canals.

The use of resin-bonded fixed partial dentures described in the early 1980s caused an conservative way to preserve tooth structure in the restorative dental community. The treatment of patients with requires long term analysis of clinical application and basic research. Failure rates of these prosthesis ranged from 3% to 55%. These varieties were orginated by different techniques, materials, tooth preparation methods and diverse clinical situations. This article review was focused on the standard long term results and in vitro studies on bond strength between metal and teeth. From this, many useful clinical guidelines to RBFPD could be adopted to clinical dentistry. For successful results, careful case selection and good clinical skills are needed. And appropriate techniques for each situations should be adopted. Also, RBFPD using new materials like all-ceramics, FRC/Ceromer was introduced.

Pain control by means of local anesthesia is an intrinsic part of clinical practice in dentistry. Several studies evaluated intraligamental anesthesia using a computer-controlled anesthetic device in children. There is a need to provide a clinical guide for the use of computerized intraligamental anesthesia in children. Intraligamental anesthesia using a computer-controlled anesthetic device was found to cause significantly lower pain perception scores and lower pain-related behavior than traditional techniques. This device proven to be effective in restorative and pulp treatment in children; however, its effectiveness in primary teeth extraction is controversial. It is important to withdraw recommendations necessity of future studies concerning the side effects of computerized intraligamental anesthesia in children. The present study aims to review different clinical aspects of computerized intraligamental anesthesia in children along with the side-effects, type of local anesthesia and postoperative pain of this technique. This study provides dentists with a clinical guide for the use of computerized intraligamental anesthesia.

The purpose of this study was to evaluate the effect of smear layer management on the interfacial morphology between dentin bonding system and dentin. Clearfil New Bond, Scotchbond Multipurpose, Prisma Universal Bond 3 and X-R Bond were used on the cervical dentinal surfaces of bovine incisor teeth. All of the dentin bonding systems were labeled with fluorescene in primer and rhodamine B in adhesive. Specimens of 2~3mm thichness were prepared by longitudinal and labiolingual sectioning. The interface between dentin bonding system and dentin was observed by flouresence imaging with a confocal laser scanning microscope. Following results were obtained. 1. In the specimen of Clearfil New Bond, dentinal tubules were widened by destruction of peritubular dentin in the course of treatment with phosphoric acid of high concentration. 2. Hybrid layer was observed in the specimen of Scotchbond Multipurpose and X-R Bond. 3. In the specimen of Prisma Universal Bond 3, the penetraton of adhesive was not observed clearly.

Invasive cervical resorption is a relatively uncommon form of external root resorption. It is characterized by invasion of cervical region of the root by fibrovascular tissue derived from the periodontal ligament. This case presents an invasive cervical resorption occurring in maxillary lateral incisor, following damage in cervical cementum from avulsion and intracoronal bleaching procedure. Flap reflection, debridement and restoration with glass ionomer cement were performed in an attempt to repair the defect. But after 2 mon, more resorption extended apically. Considering root stability and recurrence potential, we decided to extract the tooth. Invasive cervical resorption in advanced stages may present great challenges for clinicians. Therefore, prevention and early detection must be stressed when dealing with patients presenting history of potential predisposing factors.
