study of the effect of wearing complete dentures overnight on the muscular activity

The activity of the masseter and temporalis muscles was studied by direct electromyograph in 10 patients, who had worn conventional complete dentures for at least one year. Five of the patients had worn their dentures overnight, and the other five had removed their dentures at night. Results showed that the muscle activities were higher in patients who had removed their dentures at night than those who had worn the dentures overnight

Connective tissue response to tetracycline-incorporated resins

This experimental study was undertaken to determine the response of connective tissue to both self-cured and visible light cured resin containing 10% [w: w] tetracycline hydrochloride. The visible light cured resin considered the most compatible material. Marked reduction in the degree of inflammatory cell infiltration in both capsular and pericapsular tissues and increased degree of fibrous elements maturity of the fibrous capsule were noted when tetracycline was added to the test materials, during the whole observable periods

effect of metronidazole on surcutaneous tissues in rats

An attention was paid to evaluate the effect of implants visible light cured resin, and self-cured acrylic resin containing 10% metronidazole, upon the rat connective tissue. The best connective tissue response was obtained when metronidazole was added to self-cured acrylic resin, compared with other tested materials. It can be concluded that some antimicrobial agents can be added beneficially to acrylic resins used in dentistry as means of inflammation reduction, as well as to promote healing

effect of incorporating metronidazole and teracyline on the surface roughness and water sorption of visible light cure resin and acrylic resins

The usage of drugs for the topical treatment of diseases of teeth, periodontium and oral mucosa, has been attempted by many methods. The aim of this study was to discuss the surface roughness and water sorption of some acrylic resins and visible light cure resins, incorporated by metronidazole and tetracycline. From this study, it was concluded that incorporation of drugs to temporary restorations as partial denture or acrylic crowns or bridges may be useful for treatment of oral diseases, for certain periods of time
