Behavioural and socioeconomic factors associated with the simultaneous occurrence of periodontal disease and dental caries.

The aim was to evaluate the association of behavioural and socioeconomic factors with the occurrence of periodontal disease and dental caries, paying special attention to the simultaneous occurrence of these diseases. The study population consisted of 5255 dentate persons aged ≥30 years from a nationally representative survey. Caries and probing pocket depth were recorded by tooth and calculated in relation to the number of existing teeth.

The influence of a mandibular advancement plate on polysomnography in different grades of obstructive sleep apnea.

Objectives: The purpose of this study was to investigate the effect of a mandibular advancement device on different grades of obstructive sleep apnea using a relatively simple test for the apnea-hypopnea index to determine if a mandibular device will be effective.

Material And Methods: A total of 68 patients with obstructive sleep apnea syndrome (OSAS) including, 31 with mild, 23 with moderate and 14 with severe OSAS were treated with a mandibular advancement device (MAD) and monitored with polysomnography.

Results: 25 of the 31 mild, 15 of the 23 moderate and 2 of the 14 severe OSAS patients were cured of their OSAS if a post treatment apnea-hypopnea index of less than 5 is regarded as cured.

Prevalence and simultaneous occurrence of periodontitis and dental caries.

Aim: The aim of the study was to evaluate the prevalence and simultaneous occurrence of periodontal disease and dental caries in Finnish adults.

Material And Methods: The study was performed as part of the nationally representative Health 2000 Survey. The study population was 5255 subjects aged 30 years and older.

Dietary xylitol protects against the imbalance in bone metabolism during the early phase of collagen type II-induced arthritis in dark agouti rats.

The aim of the present study was to evaluate the changes in bone metabolism during the early phase of type II collagen-induced arthritis in rats and to evaluate whether a 10% dietary xylitol supplementation is able to protect against these changes. Arthritis was induced in female dark agouti rats by injections of type II homologous rat collagen emulsified with an equal volume of incomplete Freund adjuvant. In one group, the diet was supplemented with 10% xylitol.

Xylitol-supplemented nutrition enhances bacterial killing and prolongs survival of rats in experimental pneumococcal sepsis.

Background: Xylitol has antiadhesive effects on Streptococcus pneumoniae and inhibits its growth, and has also been found to be effective in preventing acute otitis media and has been used in intensive care as a valuable source of energy.

Results: We evaluated the oxidative burst of neutrophils in rats fed with and without xylitol. The mean increase in the percentage of activated neutrophils from the baseline was higher in the xylitol-exposed group than in the control group (58.

Effects of a long-term dietary xylitol supplementation on collagen content and fluorescence of the skin in aged rats.

Background: Dietary xylitol has been shown to increase the amounts of newly synthesized collagen, and to decrease fluorescence of the collagenase-soluble fraction in the skin of both healthy and diabetic rats. As in diabetic rats, a decreased rate of collagen synthesis and increased collagen fluorescence has also been detected in the skin of aged rats. We hypothesize that dietary xylitol supplementation may protect against these changes during aging.

The effect of a simultaneous dietary administration of xylitol and ethanol on bone resorption.

Our previous studies have shown that dietary xylitol supplementation diminishes bone resorption in rats, as well as protects against ovariectomy-induced increase of bone resorption during experimental osteoporosis. Interestingly, ethanol, when given simultaneously with xylitol, is known to increase blood concentration of xylitol. On the other hand, ethanol, when given alone, has been shown to increase bone resorption.
