The oral health of subjects over 75 yr and living independently in the southwest of Britain was assessed. The majority (80%) of the sample were edentulous, and a large proportion of both edentate and dentate subjects were using dentures. More than half of the denture wearers were using loose, very unhygienic, or structurally defective dentures. Mucosal pathoses were quite common, although most of the lesions were denture-induced stomatitis found in association with unhygienic dentures. The dentate subjects had, on average, 11 natural teeth, frequently with evidence of root caries and deep periodontal pockets or extreme bone loss. The oral health problems suggest that there is a significant need to develop effective methods of improving oral hygiene in this age group. The prosthetic treatment is related principally to denture repairs while there is a need to control root caries among the growing population of elderly dentate people.

Quantitative cultural studies of yeasts and bacteria were made from 7-day-old denture plaque accumulate on pieces of self-adhesive tape stuck on the fitting surface of the maxillary denture in 17 edentulous subjects with healthy oral mucosa and in 27 patients affected with denture-induced stomatitis. Significantly higher numbers of yeasts and bacteria were cultured in the stomatitis patients than in the controls. This indicates that the rate of plaque formation is increased in patients with denture-induced stomatitis. Yeasts usually constituted less than 1% of the anaerobic bacterial counts, but the percentage of yeasts was significantly higher in the stomatitis patients than in the controls. There was a significant correlation between initially higher yeast counts and improvement of the clinical condition of the palatal mucosa following antimycotic treatment. In some patients only bacteria were grown and antimycotic treatment had no effect. The study supported the contention that yeast antigens and toxins of denture plaque are significant factors in initiation and maintenance of denture-induced stomatitis. However, bacteria may also be involved as pathogens.

This study was designed to gain information on the composition and ultrastructure of bacterial plaque on the fitting surface of maxillary dentures in edentulous patients (with or without denture stomatitis of the palatal mucosa). Denture plaque was examined from 12 patients with complete dentures of unknown age. Clinical inspection of the palatal mucosa revealed that 5 suffered from denture stomatitis, while 7 exhibited a clinically normal palatal mucosa. Smears taken from the palatal mucosa and the fitting surface of the denture revealed the presence of bacteria in 11 of the 12 patients, while yeast cells were present in only 5, all of whom suffered from denture stomatitis. After the dentures were stained with a plaque disclosing solution, a 3 x 3 mm piece of the denture plate exhibiting plaque was cut out and processed for electron microscopy. Examination of sections in the light and electron microscope revealed no systematic differences between those from patients with denture stomatitis as compared with those with a clinically healthy palatal mucosa. In 2 specimens the denture was covered only by a very thin layer of condensed material which resembled the pellicle forming on teeth. In 10 the denture was covered with a deposit of microorganisms in an intermicrobial matrix. In 9 of these cocci or short rods predominated, and most of them were Gram-positive. In one specimen the plaque consisted of yeast cells only. The surface of the dentures was relatively smooth although minor irregularities were encountered. The denture material was in no instance invaded by microorganisms.

Denture stomatitis is a common oral disease in denture wearers. Multiple aetiological and predisposing factors are believed to be responsible for its initiation and progression. The aim of this study was to assess the relationship between denture age, denture hygiene habits, denture wearing and denture cleanliness in an elderly edentulous Asian population. Seventy-five edentulous patients, all wearing maxillary complete dentures were divided into two groups. The test group comprised 36 patients (14 male and 22 female) with Type II denture stomatitis. The control group comprised 39 subjects (14 male and 25 female) with clinically healthy palatal mucosa. A standardized interview and clinical appraisal were carried out. The dye disclosing method was used to assess denture cleanliness and the resultant staining pattern scored. Statistical appraisal between the two groups revealed significant differences in denture hygiene habits (P < 0.05), denture wearing behaviour (P < 0.01) and denture cleanliness (P < 0.01). No significant difference was observed in the age of dentures between the test group and controls (P > 0.05). In the studied Asian edentulous population, a relationship between denture hygiene habits, denture wearing behaviour and denture cleanliness to the presence of denture stomatitis was observed.

A 71-year-old edentulous man developed a severely painful red mouth at sites of contact with a new denture. Patch testing showed allergy to samples of the denture material and to 2-hydroxyethyl methacrylate. Patch testing to methyl methacrylate was negative. Prolonged boiling of the denture resulted in reversal of his symptoms and samples of this fully cured denture material produced negative patch tests. While allergy to acrylates is a rare cause of stomatitis, this possibility must be considered in patients presenting with oral symptoms. Material safety data sheets are unreliable in providing information regarding the type of acrylate present in the material. Hence, patch testing should be performed with a battery of acrylate allergens as well as with small samples of the denture material.

The oral health of 219 residents with mental retardation living in a long-term-care institution near Milan was assessed. The dental and periodontal status, daily habits, oral hygiene, and oral mucosal status were evaluated. Of the sample, 179 (81.7%) were males. The mean age of the residents was 61.3 years, and the degree of cooperation was evaluated as good for 131 subjects (59.8%), fair for 79 (36.1%), and poor for nine (4.1%). The percentage of residents who were edentulous was 21.5% (47 subjects), of whom 28 subjects (59.6%) were without dentures. Evaluation showed an overall DMFT of 23.1, and the average number of missing teeth was 20.5. All subjects had periodontal disease: Forty-five subjects had calculus and/or shallow pockets (4-5 mm); 61 had deep pockets (> or = 6 mm). The most common mucosal lesion was oral stomatitis (49.3%). These findings underline the need for special programs aimed at institutionalized subjects with mental retardation.

The reduction of the saliva volume leads to a number of difficulties in wearing the total dentures and favours the appearance of the denture stomatitis. For this reason, the treatment of edentulous patients with xerostomia must begin with a complete clinical examination, in order to evaluate the conditions for prosthetic replacement and the amount of the saliva volume. One can appreciate the aetiology and the degree of the saliva volume's alteration trough subjective methods (questionnaires) and objective methods (a few clinical tests, i.e. the mirror test, the pH evaluation, the examination of the saliva). During the treatment, we must pay attention to the preprosthetic measures (the oral rehabilitation), to the treatment stages (special types of impressions, the correct determination of the occlusal and intermaxillary relationships, the aspect of the internal denture's surface), and to the after-treatment phase (the patient's instructions regarding denture's wearing and hygiene, the patient's monitoring). Respecting this rules we may increase the quality of total dentures for patients with xerostomia.

The etiology of denture stomatitis remains controversial. Trauma due to unstable dentures has been suggested as an etiological factor. Therefore, we tested the hypothesis that the prevalence of denture stomatitis is reduced when mandibular dentures are stabilized by implants. Data were collected at a one-year follow-up from 173 edentulous elders who had randomly received mandibular implant overdentures or conventional dentures. The diagnosis of denture stomatitis was determined according to the Newton classification. Elders wearing conventional dentures were almost 5 times more likely to have denture stomatitis than those wearing mandibular two-implant overdentures (P < 0.0001, Fisher's exact test). Adjusted odds ratios showed that only the type of the prosthesis (AOR = 4.54, 95% CI 2.20 to 9.40) and nocturnal wear (AOR = 3.03, 95% CI 1.24 to 7.40) predict the frequency of denture stomatitis. Thus, implant overdentures may reduce oral mucosal trauma and control denture stomatitis.

Although in vitro studies on the release of antifungal agents from tissue conditioners have been done, no in vivo research on the topic could be found. The purpose of this study was to determine the in vivo effect of an antifungal agent released from a tissue conditioner on the salivary yeast count. Forty edentulous patients with denture stomatitis caused by Candida albicans were divided in two groups. Group 1 (control) was treated with a tissue conditioner only. Group 2 was treated with a tissue conditioner incorporating 500,000 U nystatin. Oral rinses were performed by both groups before treatment and every second day during treatment for a period of 14 days. Total yeast counts of the oral rinses were performed and the averages and standard deviations for both groups calculated and logarithm-transformed data of the counts over time were statistically analysed using the Wilcoxon signed-rank test. The average oral rinse yeast count of the control group decreased up to day 4. Thereafter, the count increased till the end of the test period. At day 14, the oral rinse yeast level was higher than the pre-treatment level. The average yeast count of the test group decreased up to day 7. Thereafter, the count increased but remained significantly lower (P=0.01) than the control group and did not return to its pre-treatment level. A nystatin-containing short-term denture liner significantly decreases the salivary yeast count of patients with denture stomatitis compared with a liner without nystatin.

The microbiota of the denture plaque biofilm colonizing the fitting surface of dentures in edentulous subjects with healthy palates (n = 20) and in edentulous subjects with denture stomatitis (n = 20) was studied. The numbers of bacteria colonizing the dentures of healthy subjects was significantly less than the numbers colonizing the dentures of stomatitis subjects. The proportions and frequency of isolation of mutans streptococci, lactobacilli, bifidobacteria and yeasts were significantly (P < 0.05) greater in the subjects with denture stomatitis. The proportions of these organisms in the denture plaque biofilm of the subjects with denture stomatitis were similar to those found in carious lesions, indicating that the site is a low pH environment. The predominant bifidobacterial species in the mouths of dentate subjects is Bifidobacterium dentium but in the edentulous subjects wearing dentures B. dentium was isolated from only one of the 20 subjects with denture stomatitis and from none of the 20 subjects with healthy palates. Instead, Bifidobacterium breve, Bifidobacterium scardovii and Bifidobacterium longum subsp. longum were isolated. Only a single non-oral bifidobacterial species was isolated from each individual and repetitive extragenic palindromic- and BOX-polymerase chain reaction typing methods indicated that the same genotypes were shared between subjects. Using deferred antagonism spot plate assays, interspecies inhibition was demonstrated between oral isolates of B. dentium, B. breve, B. scardovii and B. longum subsp. longum. Here we have shown that bifidobacteria and caries-associated microbiota are present in denture plaque at levels similar to those of carious lesions and B. dentium cannot be maintained in an edentulous mouth.
