The oral cavity provides an ideal and unique environment for study of biological processes involving metallic dental aids. Dental materials within the mouth interact continually with physiological fluids. Oral tissues are exposed to a veritable bombardment of both chemical and physical stimuli as well as the metabolism of many species of bacteria; yet, for the most part, oral tissues remain hea...

The purpose of this study was to examine narrowing of the dental pulp cavity in patients undergoing long-term administration of steroids, by means of intraoral radiographs. The subjects were 20 patients under long-term steroid treatment (the steroid group), and 15 patients who were not receiving steroids (the non-steroid group), who visited the Clinic for Persons with Disabilities, University H...

While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dent...

The clinical examination reveal a patient in good shape . Examination of the nasal cavities found some blood clots in the left nasal cavity , the suction...

Background. Several studies were reported on the prevalence, and relationship between the existence of Helicobacter pylori (H. pylori) in oral cavity and in stomach of patients. The purpose of this study was to systematically review the existing literature on the presence of H. pylori in the oral cavity and its link to gastric infection, the existence of coinfection, and the impact of anti-H. p...

Lasers were introduced into the field of clinical dentistry with the hope of overcoming some of the drawbacks posed by the conventional methods of dental procedures. Since its first experiment for dental application in the 1960s, the use of laser has increased rapidly in the last couple of decades. At present, wide varieties of procedures are carried out using lasers. The aim of this review is ...

Probiotics have been extensively researched for their beneficial health promoting effects. Previously, the mainstream of research was limited to the gastrointestinal flora, but in the past few years it has been more focused towards the oral and dental health perspectives. Few randomized controlled trials have been conducted in this area, though the investigations on probiotics versus oral and d...

As the emphasis shifts from damage mitigation to disease prevention or reversal of early disease in the oral cavity, the need for sensitive and accurate detection and diagnostic tools become more important. Many novel and emergent optical diagnostic modalities for the oral cavity are becoming available to clinicians with a variety of desirable attributes including: (i) non-invasiveness, (ii) ab...
