Root amputation and retrograde filling of pulp canals is a useful technique in the treatment of periapical dental infections in horses, thus allowing tooth preservation. The limitations of the technique are the need for careful case selection and the difficulty in creating a hermetic apical seal. Authors’ addresses: Royal Veterinary College, Hawkshead Lane, North Mymms, Hatfield, Hertfordshire,...

Adhesive techniques are now used for many dental restorative materials, including amalgam. Several generations of dentine bonding agents have been developed, mainly for bonding composite resins. When bonding is used with amalgam restorations, the need for retention and resistance form is reduced, the seal is improved, and some procedures, such as amalgam sealants, which were not previously poss...

Infection is the primary failure modality for transcutaneous implants because the skin breach provides a route for pathogens to enter the body. Intraosseous transcutaneous amputation prostheses (ITAP) are being developed to overcome this problem by creating a seal at the skin-implant interface. Oral gingival epithelial cell attachment creates an infection-free seal around dental implants. Howev...

Soft tissue integration in the transmucosal zone of dental abutments supports the peri-implant tissues, improves esthetics, ensures soft tissue seal against microorganisms, and preserves crestal bone level. The aim of this literature review was to define the most favorable surface topography and macrodesign of the transmucosal zone of abutments to achieve optimal soft tissue seal. An electronic...

Mineral trioxide aggregate is a recently introduced dental material. It may be used to seal perforations, make retrograde fillings in root-end resections, seal open apices, or cap vital pulps. In this review of the literature, physical, chemical, and biologic properties of MTA are discussed. Studies have suggested that MTA provides a better seal than formerly used materials such as IRM, amalgam...

adhesive (green). _Besides the physical and mechanical properties of dental amalgam, one of the main reasons for its success is its clinical simplicity and forgiving technique. The derisory “drill and fill” slogan associated with dental treatment pertinently describes the provision of an amalgam restoration. The usual protocol for amalgam restorations is a single-stage procedure. Following deca...

Pulp vitality is extremely important for the tooth viability, since it provides nutrition and acts as biosensor to detect pathogenic stimuli. In the dental clinic, most dental pulp infections are irreversible due to its anatomical position and organization. It is difficult for the body to eliminate the infection, which subsequently persists and worsens. The widely used strategy currently in the...

Prosthetic rehabilitation of an edentulous cleft lip and palate patient with a combined hard soft defect is great challenge, due to the lack retention obturator prosthesis as result its weight inability obtain border seal. Dental implants improve retention, stability, occlusal function prostheses when used in carefully selected cases. This clinical report presents unilateral who has defects atr...

Within the limitations of this study, our results indicate that microtomography, with proposed semi-automatic algorithm, is a useful tools for three-dimensional quantitative evaluation of dental root canal fillings. In canals filled with thermoplastic gutta-percha and Tubli-Seal, voids at the interface between the filling and canal dentine deserve special attention due to of their periapical lo...
