statement of the problem the incidence of infectious diseases is considerably high among dentists and the team of dental care providers because of frequent exposure to blood and saliva. therefore, infection control regulations must be taken seriously in order to prevent cross-contamination purpose the aim of the present study was to investigate infection control measures in dental offices in ha...

INTRODUCTION Information on the origin of dental fear and uncooperative behavior in a child patient is important for behavior management strategy. The effects of environmental factors have been comparatively less studied, especially in an Indian scenario. OBJECTIVES To find the association of (1) age, gender, family characteristics, previous medical, and dental experiences with dental fear an...

soils bacteria are frequently faced with various adverse environmental conditions and have developed a complex regulatory network to respond rapidly to environmental changes. in this study usefulness and applicability of stress proteins of bacteria which are produced after stress conditions were examined. the adaptation of soil bacteria involves the induction of stress proteins provide a nonspe...

the role of zinc (zn) in enhancing defense capacity of several plants against salinity has been demonstrated but there is limited information on the impact of zn nutrition on alleviating salinity-induced oxidative damage in olive. one-year-old seedlings of two varieties of olive (olea europaea l. cvs. frontoio and conservolea) supplied with three zn levels (0, 1 and 5 mm in the form of znso4.7h...

The interruption of odontogenesis by any etiological factor may result in dental anomalies. Apart from the environmental factors, the impact of genetics in dental anomalies was found to be a factor in different levels. Many authors had questioned a common genetic defect resulting in different phenotypic conditions such as absent, malformed, malposed or ectopic teeth. Because the multidisciplina...

OBJECTIVE This paper focused on optimal stress distribution in the mandibular bone surrounding a dental implant and is devoted to the development of a modified Osteoplant® implant type in order to minimize stress concentration in the bone-implant interface. MATERIAL AND METHODS This study investigated 0.4 mm thick layers of two elastomeric stress barriers incorporated into the dental implant ...

Using finite element method (FEM), this study sought to investigate how the thickness and Young's modulus of cortical bone influenced stress distribution in bone surrounding a dental implant. The finite element implant-bone model consisted of a titanium abutment, a titanium fixture, a gold alloy retaining screw, cancellous bone, and cortical bone. The results showed that von Mises equivalent st...
