Dentist:  Richard Rubinstein Practice location:  Farmington, Hills, MI Type of practice:  Endodontic This patient was referred for apical microsurgery on a premolar (Figure 1): Figure 1: Pre-operative radiograph showing a radiolucency on the premolar and the sinus tract. After anesthesia was established, I brought the surgical operating microscope into the field and made a full-thickness freegingival margin flap to create […]...

Dentist: Ryan Walsh Practice location: Keller, TX Type of practice: Endodontic A patient sought treatment for a chief complaint of a gingiva/tooth abscess in a previously endodontically treated tooth (Figure 1): Figure 1: Pre-operative periodical radiograph of tooth being retreated. After accessing the mesiobuccal canal, I detected a prior furcation strip perforation. I removed the remaining gutta percha, cleaned and shaped all canals, and placed a calcium hydroxide […]...

Dentist: Franklin Tay Practice location: Augusta, GA Type of practice: Endodontic This patient was referred to me after a tooth that was previously treated endodontically was failing to resolve the periapical lesion. (Figure 1): Figure 1: Pre-op periapical radiograph of tooth for retreatment. After anesthesia was administered, a full thickness free-gingival margin flap was created […]...

ABSTRACT INTRODUCTION: Mineral trioxide aggregate (MTA), white and gray, has many uses in endodontic therapy but is limited by its difficult handling characteristics. This study compared the physical and chemical properties of white MTA (WMTA) with three experimental root-end filling materials: Capasio (Primus Consulting, Bradenton, FL), Ceramicrete-D (Tulsa Dental Specialties/Argonne National Laboratory, Argonne, IL), and […]...

ABSTRACT INTRODUCTION: Generex A and Generex B (calcium silicate based), Capasio (calcium-phospho-alumino silicate based) along with Ceramicrete-D (magnesium phosphate based) are being introduced as a new generation of endodontic materials with the potential to facilitate bone healing. The aim of this study was to evaluate the biocompatibility and osteogenic potential of these new materials by […]...

ABSTRACT Fluoride-releasing restorative materials are available for remineralization of enamel and root caries. However, remineralization of dentin is more difficult than remineralization of enamel due to the paucity of apatite seed crystallites along the lesion surface for heterogeneous crystal growth. Extracellular matrix proteins play critical roles in controlling apatite nucleation/growth in collagenous tissues. This study […]...
