OBJECTIVE The purpose of this study was to perform a radiographic follow-up evaluation after a 12-month healing period, following crown lengthening surgery. MATERIAL AND METHODS Twenty-three periodontally healthy subjects (mean age 32.5 years) that required crown lengthening surgery in premolars were recruited. In a total of 30 premolars, full thickness flaps, osseous resection, and flap sutu...

Introduction: Biological Width is needed to maintain the health of gingiva around teeth that need restoration. Crown Lengthening (CL) surgery can be used to prevent  invading the BW by sub-gingival restoration. The aim of this study was to evaluate gingival indices before and after CL surgery. Materials and Methods: In this analytical-longitudinal study, 23 teeth of 18  patients referred to ...

The use of resin cements in combination with dentin bonding agents can result in superior attachment of prostheses to tooth structure. This paper describes four clinical cases in which dentin-bonded resin cements were used to overcome retention problems. In the first case, a detached fixed partial denture, which was in good condition when separated, was recemented to abutment teeth prepared wit...

Background: Periodontitis is a multifactorial chronic inflammatory disease characterized by destruction of tooth-supporting tissues. Environmental and genetic factors as well as the immune system participate in this process. Recent studies have attempted to elucidate the role of cytokine networks involved in periodontal diseases. Objective: To assess and compare the levels of IL-4, IL-6 and IL-...

Innovations in material science and clinical techniques have expanded the number of treatment options available for nonvital anterior teeth. These options include the use of composite to fill the access opening with no additional treatment, crown placement, orthodontic extrusion, crown lengthening with or without orthodontic extrusion, dowel restorations with crown placement, and fixed bridge o...

This case report demonstrates sequential periodontic, orthodontic and prosthodontic treatment modalities to save and restore deep horizontally fractured maxillary central incisor. The location of fracture was deep in the mucosa which reveals less than 2 mm of tooth structure to receive the crown. The procedures like surgical crown lengthening, endodontic post placement, orthodontic forced erupt...

Aesthetic crown lengthening is one important chapter in contemporary periodontology. Traditionally, this procedure is performed using a flap elevation to a full exposure of the underling bone to allow for osteotomy/osteoplasty. However, in well-indicated cases, it is possible to meet that purpose using a flapless approach; i.e. without a flap elevation, in which the osteotomy is performed throu...
