background and aims. current chemical methods may not efficiently disinfect dental stone casts. the aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. materials and methods. in this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...

This trial was designed to compare both corn and citrus pulp with added UIP as potential supplements for growing cattle fed low quality bahiagrass hay. Citrus pulp supplements produced gains similar to corn and performance was enhanced as level of UIP increased. Maximum ADG was achieved at 0.48 lb of added UIP. It is unclear if 0.48 lb of added UIP is the optimal level of supplementation becaus...

BACKGROUND Prosthodontic procedures involving dental impressions, stone casts, record bases and prostheses may cause transmission of microorganisms between the patient, the dentist, auxiliary staff and laboratory personnel. In recent times, microwave radiation has gained wider acceptance in the field of applied science and has been used to reduce concentrations of bacteria and fungi, to dry den...

UNLABELLED The type IV dental stone is widely used for the fabrication of dyes and master casts for fixed and removable partial prostheses. It is typically normal to wait at least 24 hours for the casts to dry prior to beginning the laboratory procedures. The waiting time has been shown to be greatly reduced by using microwave drying. OBJECTIVE This study evaluated the influence of drying tec...

Two new species of cheilostome Bryozoa are described from continental-slope habitats off Mauritania, including canyon and cold-water coral (mound) habitats. Internal structures of both species were visualised and quantified using microcomputed tomographic (micro-CT) methods. Cellaria bafouri n. sp. is characterised by the arrangement of zooids in alternating longitudinal rows, a smooth cryptocy...

BACKGROUND. Accurate determination of the pulp status is the most important part of conservative pulp therapy. AIM. The aim of this study was to assess the ability of thermal and electrical pulp tests to assess the pulp status in primary teeth. DESIGN. Seventy-eight primary molar teeth in 36 children were investigated. Fifty-six teeth had unknown pulp status in need of endodontic treatment, and...

Dental trauma creates serious functional, aesthetic and psychological problems for the patient. The known developments in recent years in the area of materials and techniques related to direct composite resin restorations provide for the dentists direct conservative solutions that allow both morphology and aesthetic restoration and preservation of pulp vitality in many of the clinical situation...

Introduction: Many epidemiological studies have been conducted to determine the prevalence of the various types of the dental anomalies. The aim of the present study was determination of developmental and acquired dental anomalies in patients attending the faculty of dentistry in Rasht, Iran. Materials and Methods: In this retrospective cross-sectional study, 1224 digital panoramic ra-diographs...

BACKGROUND Occupational injuries cause major health problems, which the developed, developing, and underdeveloped nations worldwide are facing today. The present study aimed to assess dental caries, periodontal health of stone mine workers, and the relationship between wasting diseases and the years of working experience. METHODS The study population comprised 510 men, selected based on the s...
