摘要:

Cementum surface alterations induced by 1-hydroxyethylidene-1,1-bisphosphonate (HEBP) in the maxillary first molars in rats were studied by means of scanning electron microscopy. Single or triple injections of HEBP inhibit the formation of acellular extrinsic fiber cementum and delay the formation of cellular mixed-fiber cementum. The results indicate the importance of acellular extrinsic fiber cementum as a protection barrier against root resorption and the different mechanisms underlying the formation of the two cementum varieties.

摘要:

The aim of the present study was to investigate the impact of general health and life-style factors on the number of remaining teeth in 68-year-old men living in the city of Malmö, Sweden. The study included 483 men (participation rate, 78%). Poor self-assessed health, frequent medical attendance, diabetes, and oral dryness were related to fewer remaining teeth. Number of teeth was negatively correlated to concentrations of triglycerides and alkaline phosphatases in serum and to glucose in blood but positively correlated to serum urea. Various dietary variables including consumption of sucrose-containing products and nutritional quality were not related either to number of teeth or to prevalence of edentulousness. Smoking and high consumption of coffee or alcohol were associated with fewer remaining teeth. Multiple logistic regression analyses showed that social class, frequency of dental attendance, smoking, and serum concentrations of triglycerides and urea had an independent effect on number of teeth.

摘要:

Contrary to what is observed in many Western societies, the caries prevalence among children and adolescents in the Baltic States remains high. The aims of the present study were to describe the caries prevalence and oral hygiene among 7-, 12-, and 15-year-old Lithuanians and to correlate the caries prevalence with fluoride content in the drinking water, oral hygiene, gender, ethnicity, and pattern of sugar consumption. The investigation was based on cluster samples, and the clinical investigation was performed in accordance with criteria denned by WHO. High DMFT values were registered (mean DMFT = 1.3 among 7-year-olds; DMFT = 4.9 among 12-year-olds and 7.0 among 15-year-olds) and were associated with low fluoride content in the drinking water and poor oral hygiene. Girls showed higher DMFT values than boys. No correlation between pattern of sugar consumption and caries prevalence could be disclosed.
