Protease activity was measured in dental plaque collected from patients with or without supragingival calculus. Plaque specimens from the calculus group showed significantly greater protease activity in the presence of 0.05% sodium thioglycollate than did those from the non-calculus group. No significant difference between the two groups was observed in the protease activity without sodium thio...

Pathogenic bacteria located in the subgingival area can cause periodontal diseases, gingivitis, and periodontitis. These bacterial species stick to the root surfaces and are found in a complex structure called dental plaque, which is a form of biofilm. Dental plaque, where appropriate oral hygiene is lacking, may become calcified, thereby creating calculus mainly formed from crystalline. The po...

Calculus consists of mineralised dental biofilm on the surfaces of teeth and dental prosthesis, the location of which can be detected by using a periodontal or an electronic probe. Detection of subgingival calculus is critical for successful treatment outcome in the management of periodontal patients. The aim of this study was to detect subgingival calculus using manual and electronic probe and...

BACKGROUND The present paper describes the oral manifestations in a 16-year-old boy previously diagnosed with Apert syndrome. PATIENT AND METHODS The extraoral and intraoral pathological findings were recorded. The following intraoral parameters were recorded: plaque and calculus deposits, dental caries, periodontal status, malpositions, and occlusion. For the upper anterior teeth, dental sha...

Current recommendations for periodontal health maintenance emphasize toothbrushing, flossing and periodic dental checkups. The purposes of this study were to examine (1) the effects of these practices on periodontal health and (2) the relationships of demographic and socioeconomic variables with these behaviors and with periodontal health. Adults (n = 319) in the Detroit, Michigan tri-county ar...

OBJECTIVE The aim of this study is to determine the prevalence of dental caries, periodontal disease and the condition of and need for dental prosthesis in individuals over the age of 64. DESIGN A cross-sectional, descriptive and observational study was carried out among all the residents in 3 Centres for the Aged in Vigo-Spain. The standardized criteria of the DMFT (Decayed, Missing and Fill...

Dental diseases, including periodontal disease, at times become vexacious health problems on submarine patrols. Dental calculus is thought to play a role in periodontal disease. Little is known about the oral factor on patrol which may influence the calculus formation rate. Past studies indicate that the salivary pH may have a role in this formation. The saliva from the anterior sublingual pool...

Dietary reconstructions based on plant microfossils, such as starch grains and phytoliths, have been useful in increasing our understanding of past human populations. Microfossils have been recovered from sediments, stone tools, and, more recently, dental calculus. Methods for recovering microfossils from dental calculus have yet to be firmly established and there is some question about potenti...

Oral disorders of the dog represent for veterinarians a medical challenge and an important field of interest from the economical point of view. Although many epidemiological studies on dental diseases in beagles bred under controlled conditions have been realized, information on frequency of these alterations in populations of pet dogs, especially in Central Europe, is far from complete. The ai...
