Denture cleansing: a comparison of two methods.

A paste brushing method (Complete) and soaking in either of two denture cleanser tablet solutions (Efferdent or Polident) were compared for denture cleansing effectiveness as measured by plaque level. The 12-week product use period with weekly evaluations allowed an assessment of plaque reaccumulation on the denture surface as well as the effect of a single cleansing event and the contribution of bleaching to the total plaque-cleansing activity. The paste/brushing method was consistently the more effective procedure for removal of denture plaque. However, the bleaching effects of the effervescent tablets could be useful in an overall denture hygiene program.

Effect of a denture adhesive on complete denture dislodgement during mastication.

A method of evaluating the denture stabilizing effects of a denture adhesive by means of counting denture dislodgements during the eating of a standardized portion of a test food is described. A reduction in the number of such dislodgements after application of a denture adhesive, as compared to eating the same food without adhesive applied to the denture, was used as a measure of adhesive effectiveness. Subject responses to a number of denture-performance satisfaction parameters were also obtained. With a test adhesive, significant reductions in dislodgement were found using steak, taffy-apple, a hard-roll sandwich, and celery as test foods among 16 subjects with dentures that fit well. Analysis of subjective evaluations indicated that the test adhesive was perceived as having effected: (1) improved chewing ability, (2) reduced denture wobble, (3) improved confidence, (4) increased comfort, and (5) reduced amount of food particles collecting under the denture, all to a significant degree (p < .01). It is suggested that additional data from controlled clinical studies are needed to allow proper assessment of the usefulness and possible abuse effects of denture adhesive products. This method, and the resulting data, are offered as a stimulus to the end.

Observations of denture-supporting tissue during six months of denture adhesive wearing.

The regular use by denture wearers of an appropriate denture adhesive is not associated with any increased incidence in mucosal irritation. The use of such an adhesive can, in fact, reduce the likelihood of the occurrence of tissue irritation and, at the same time, provide the denture wearer with specific benefits--both physical and psychological. The use by 111 denture wearers of a natural gum or a synthetic polymer adhesive for six months was not accompanied by any increase in mucosal irritation of denture bearing tissues. Mucosal irritation present in certain of the subjects at the start of the study was eliminated in almost all cases with the continuing use of the assigned adhesive during the six-month observation period.

Clinical evaluation of a new treatment for dentinal hypersensitivity.

The effectiveness of potassium nitrate (5%, delivered in a low abrasive toothpaste vehicle) as a daily home treatment of dentinal hypersensitivity was evaluated in a 4-week, double-blind, parallel, comparative study of 27 subjects with the condition. Hypersensitivity levels in affected teeth were assessed by two quantifying methods--electrical stimulus and cold air stimulus--and by a subjective recall procedure. The results from these three methods of assessment indicate that potassium nitrate desensitizes hypersensitive teeth to a significant degree. The therapeutic response (decline in dentinal hypersensitivity) to potassium nitrate was evident within 1 week and increased continuously for the length of the study period. Sensitivity threshold of teeth adjudged to be normally sensitive were not altered by treatment with potassium nitrate, nor did the agent exert any discernable effects on oral tissues.

Physical-chemical aspects of denture retention and stability: a review of the literature.

The physical-chemical mechanism of retention of dentures is a highly complex one. A review of the literature suggests in addition that retention also is a personal phenomenon under the control of numerous factors. Chief among the factors involved in the retention of a well-adapted denture are the forces related to the wetting of the denture and of the mucosal surfaces and the cohesive or intermolecular characteristics of the saliva. The ill-fitting denture most often results from an increase of variation in the denture-mucosa interspace, probably due to bone resorption rather than to any major changes in the physical-chemical factors.

An evaluation of two methods for the quantitation of dentinal hypersensitivity.

In a well-controlled, double-blind, parallel study design using burnishing with 33% sodium fluoride paste and "sham" burnishing with a placebo paste, both a cold air stimulus method and an electrical stimulus method can discriminate between levels of dentinal hypersensitivity. Correlation between the scores obtained by the methods was significant. The electrical stimulus method discriminated between the sodium fluoride and placebo effects to a greater degree than did the cold air method. Use of these methods should broaden the scientific foundation and rationale for evaluating the condition of dentinal hypersensitivity and the agents designed for treatment of persons with this condition.

The correlation between organoleptic mouth-odor ratings and levels of volatile sulfur compounds.

An organoleptic rating (OR) technique and gas-liquid chromatography were employed to study the relationship between oral-malodor ratings and the corresponding concentrations of oral volatile sulfur compounds (VSC) in a total of 102 subjects in two separate studies. Both studies demonstrated a statistically significant positive correlation between the intensity of perceived oral malodor and the concentration of VSC (H2S + CH3SH) emitted by individual subjects.
