BACKGROUND AND OBJECTIVE: Tissue engineering by using recombinant human (rh) growth factor technology may offer a promising therapeutic approach for treatment of gingival recession. Fibroblast growth factor-2 (FGF-2) has shown the ability to promote periodontal regeneration. Gelatin/beta-tricalcium phosphate (gelatin/β-TCP) sponges have been developed to control the release of growth factors. The present study evaluated the periodontal regenerative efficacy of rhFGF-2 by comparing gelatin/β-TCP sponges incorporated with rhFGF-2 to the scaffolds alone in artificially created recession-type defects in dogs...

INTRODUCTION: Calcifying odontogenic cysts (COC) represent 0.3-0.8% of all odontogenic cysts. We describe the finding and the treatment of a COC in a 67-year-old female. OBSERVATION: An asymptomatic well-limited radioluscent mandibular lesion was fortuitously discovered on the panoramic X-ray in the periapical region of teeth No. 33 and 34. Treatment consisted in enucleation and curettage. Histologic examination was in favour of a COC. At 6 years follow-up, X-ray control showed new bone formation and the patient was free of symptoms...

INTRODUCTION: Reciprocating instruments were developed to improve and simplify the preparation of the root canal system by allowing greater centralization of the canal and requiring a shorter learning curve. Despite the risk of instrument separation, using a reciprocating instrument in more than 1 case is a relatively common clinical practice. The aim of this study was to evaluate the fracture resistance of Reciproc (R25; VDW, Munich, Germany) and WaveOne (Primary; Dentsply Maillefer, Ballaigues, Switzerland) instruments according to the number of uses during the preparation of root canals in up to 3 posterior teeth...

OBJECTIVES: Dentists can choose between metal and fiber post systems to provide post-retained restorations. The risk of tooth loss and other complications differs between different post systems, as do the initial treatment costs. We aimed to assess the cost-effectiveness of (1) cast metal (MC), (2) preformed metal (MP), (3) glass fiber (GF), and (4) carbon fiber (CF) post-retained restorations. METHODS: A mixed public-private payer's perspective within German healthcare was taken...

INTRODUCTION: Teeth with a palatal radicular groove are challenging to diagnose, treat, and save. We classified this condition using cone-beam computed tomographic (CBCT) cross-sectional configurations combined with radiographic and morphologic observations during an intentional replantation procedure to identify and analyze the characteristics of palatal radicular grooves comprehensively as a reference for diagnosis, treatment planning, and prognosis evaluation of this condition. METHODS: Eight cases with palatal radicular grooves present in permanent maxillary incisors were investigated by radiography and CBCT imaging before intentional replantation...

INTRODUCTION: In order to understand the mechanical behavior of a weakened incisor, this study aimed to evaluate the stress distribution caused by different alveolar bone heights and cement layer thickness. METHODS: A finite element analysis was conducted for this investigation. An intact maxillary central incisor was initially modeled, and the bone of the models was modified in order to simulate 4 levels of bone height: BL0 (no bone loss), BL1 (1/3 bone loss), BL2 (1/2 bone loss), and BL3 (2/3 bone loss)...

STATEMENT OF PROBLEM: Glass fiber post cementation procedures have undergone significant development. Relining the post with composite resin is a technique that aims to reduce resin cement thickness and consequently problems inherent to polymerization. Evidence is sparse regarding the efficacy of bonding procedures at increasing depths (from cervical to apical) using different adhesive cementation techniques. PURPOSE: The purpose of this in vitro study was to evaluate the push-out bond strength (PBS) of composite resin relined glass fiber posts cemented to bovine root dentin using different adhesive cementation protocols...

STATEMENT OF PROBLEM: As the cosmetic demands of patients increase, determining the appropriate dimensions of the maxillary anterior teeth has become increasingly relevant. The relationship between facial measurements and tooth size provide guidance for maxillary anterior tooth size selection. However, most publications on this topic have focused on the white population, and more data for tooth sizes and their proportions in other ethnicities are needed. PURPOSE: The purpose of this observational study was to investigate the relationship between the mesiodistal dimensions of the 6 maxillary anterior teeth and the bizygomatic width, interpupillary distance, intercanthal distance, interalar width, and intercommissural width of individuals of Asian, African-American, and white ethnicities...

STATEMENT OF PROBLEM: The number of partially dentate adults is increasing, and many patients will require replacement of missing teeth. Although current treatment options also include fixed partial dentures and implants, removable partial dentures (RPDs) can have advantages and are widely used in clinical practice. However, a significant need exists to advance materials and fabrication technologies because of the unwanted health consequences associated with current RPDs. PURPOSE: The purpose of this review was to assess the current state of and future need for prosthetics such as RPDs for patients with partial edentulism, highlight areas of weakness, and outline possible solutions to issues that affect patient satisfaction and the use of RPDs...

Robert D Walter, Charles J Goodacre
OBJECTIVE: When multiple visible teeth are prepared, the prolonged treatment time may lead to patients needing a break that requires them to leave the operatory. Such a situation allows the patient to view their prepared teeth, a process that can be disconcerting to some patients. CLINICAL CONSIDERATIONS: An intraoperative provisional restoration can be made by using a thermoplastic vacuum-formed matrix of the patient's teeth that is filled with white-colored impression material and then placed over the prepared teeth to form a provisional restoration...
