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.
The staff of this nursing home demonstrated positive knowledge of periodontal disease and denture care. However, their knowledge of dental caries revealed substantial room for improvement. This could signal an area for future staff training and development. Such efforts would help establish a team of caregivers who can improve the oral health and quality of life for residents in the nursing home.
Microwaveable acrylic denture resins are believed to provide an effective means of repairing fractured dentures. This in vitro investigation compared the bond strength of a microwaveable acrylic resin as a denture repair material to two established auto-polymerized resins. Fifty-one specimens were made using Lucitone 199 as a simulated denture base, and were then divided into three groups of 17 samples each. Each test group was bonded with the following acrylic resins: Acron Mc, Rapid Repair and Palapress. A shear bond strength test was carried out 24 h after the samples were bonded. Fracture analysis showed that bond failure was adhesive for all groups. Shear bond values showed a statistically significant difference at P < 0.05 level between Acron Mc and Rapid Repair; Palapress and Rapid Repair, and indicated that Acron Mc and Palapress were superior to Rapid Repair as a repair material. However, there was no statistical difference found between Acron Mc and Palapress. Microwaveable acrylic resins produce repaired junctions of adequate strength.
Ab stractChemical cure resin materia.ls are generally used in the repair of dentures. Different repair resins used may yield different results. The bond strength of three autopolymerizing resins were evaluated using a torsional test method. The results showed that Palapress and Caulk resins had a higher repair strength than Rapid Repair resin .Key words: Denture repair resins, bond strength, torsion tests evaluation.(Received for publication March 1995. Revised June 1995. Accepted July 1995 Int roductionAlthough resins for denture repairs are not as extensively studied as adhesives to dentine, porcelain or enamel, the importance of denture repairs cannot be underestimated. Huggett et al. 1 cited that nearly three-quarters of a million dentures were repaired each year in England and Wales at a cost of £4 .7 million (at 1987 price) to the National Health Service (UK) and an estimated similar amount is spent by patients privately. Most of these repairs are due to failure of polymethylmethacrylate (PMMA) denture bases.Smith 2 noted that denture failure depends on the shape, conditions of loading, inherent residual stresses and mechanical properties of the denture base. Farmer 3 listed various clinical factors such as improperly contoured mandibular occlusal plane, high frenal attachment, incorrect occlusal schemes, heavy occlusal forces, poor adaptation of the denture base to the residual alveolar ridge and denture base thickness as primary causes of denture fractures. Vallittu et al. 4 noted that the highest incidence of denture fractures occurred between 16-36 months after being in service.The clinician must often decide whether to repair or replace the broken denture . To minimize inconvenience to the patient and save costs in the reconstruction of the dentures, quick and reliable denture repairs are often necessary. Success depends on correcting the offending clinical cause and a strong repair junction. Confidence in the repair rests on the repair resin. There is, therefore, a need to fully characterize the bond strength of the denture repair resins available in the market.The purpose of the present study was to use the torsional test proposed by Stewart et al. 5 to assess the relative merits of denture repair resins. It seeks to compare the shear bond strength of three commercially available acrylic resin denture repair materials in vitro.A torsional test was chosen as the stress exerted on the specimen has a significant shear component and is, therefore, closer to the clinical situation. The torsion specimen also has a uniform state of stress at any point on the specimen surface and this state of stress is less dependent on parallelism and specimen geometry than for diametral or three-point bending tests.
Dentures are routinely removed from the oral cavity before general anesthetic procedures. They are only reinserted much later when the patient returns to the room. This clinical report describes an edentulous patient who developed acute tongue swelling from venous congestion as a result of tongue recovery from general anesthesia. Her complete dentures were used to separate the residual ridges during the recovery period and relieved the congestion. Denture insertion increased the height and volume of the oral cavity, which reduced pressure on the tongue, preventing a cycle of tongue compression, congestion, and swelling. This unusual complication suggests that it may be prudent for the edentulous patient to be accompanied by their dentures in the perioperative period.
