BACKGROUND: Interdental papilla occupies the space between two adjacent teeth. Its contour and health are regarded with utmost importance in esthetic dental therapy. The loss of papillary height can result in open gingival embrasures, phonetic problems, food impaction, and esthetic concerns: therefore in order to prevent its loss and to better understand the challenges of regenerating the lost gingival papillae, it is crucial to recognize the factors that influence papilla form. AIM: The purpose of this study is to evaluate various factors associated with the fill of interdental spaces by gingival papillae MATERIAL AND METHODS: 150 interdental papillae in 30 patients were assessed with clinical and study models...

STATEMENT OF PROBLEM: Monitoring performance of glass-ceramic based indirect restorations using radiographic imaging might be difficult due to their low radiopacity. Therefore, materials used for their cementation must possess adequate radiopacity. PURPOSE: This study determined radiopacity of a group of resin-cements used for adhesive-cementation of glass-ceramic-based restorations using digital radiography. METHODS: Two specimens were prepared from a group of resin cements (VariolinkII-opaque, VariolinkII-opaque (base), VariolinkII-Transparent, VariolinkII-Transparent (base), Nexus, RelyX Unicem, RelyX ultimate, Duolink, Monocem and Resinomer) and longitudinal sections of same thickness were obtained from molar and premolar...

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...

OBJECTIVE: Extraction-socket resorption is considered a major problem that can limit implantological rehabilitation options and compromise the esthetic outcome. Surgical techniques to reduce remodeling are of restricted predictability and commonly require several surgical interventions and grafting. This increases the treatment cost and places a physical and psychological strain on the patient. This clinical case report presents a replacement of an upper canine using the socket-shield technique (SST) with a CAD/CAM surgical guide, resulting in a predictable, high esthetic, and functional result...
