Factors affecting the distribution and prevalence of oral mucosal lesions in complete denture wearers.

OBJECTIVE: To determine the frequency of the oral lesions related to gender, age, the length of time of denture usage, education level and economic status. METHODS: The 153 patients with old complete dentures (CD) were asked to participate in the investigation. The subjects (76 male and 77 female) were 37-85 years of age with a mean age of 61.8 ± 9.8 years. Education, economic status and age factors were estimated in subgroups. The data obtained were evaluated by one-way anova, Mann-Whitney U-test, Kruskal-Wallis test, Student's t-test and chi-squared test. The level of statistical significance was set at p<0.05. RESULTS: The patients who had denture stomatitis and traumatic ulcers were statistically significantly older than the ones who did not have these lesions (p<0.05). Based on the length of denture usage, patients who had a flabby ridge, fibrous inflammatory hyperplasia, traumatic ulcers (p<0.01) and denture stomatitis (p<0.05) were using their dentures statistically significantly longer than the ones who had healthy tissues. CONCLUSIONS: The CD wearers should be advised to visit their dentist regularly to prevent oral mucosal lesions due to the changing supporting tissues during the length of denture usage and to improve their quality of life.

Factors triggering the oral mucosal lesions by complete dentures.

Oral mucosal lesions may represent acute or chronic reactions to factors related with dentures. The aim of this study was to determine the frequency of the oral lesions related to gender, age, the length of time of denture usage, the balance of denture and cleaning methods and frequency. The 106 patients who have old complete dentures came to the Dental Faculty of Marmara University, Istanbul (Turkey) to have new complete dentures were asked to participate in the investigation. The subjects (51 men and 55 women) were 37-80 years of age with a mean age of 60.28+/-10.52 years. All main factors were estimated in subgroups: cleaning methods and frequency were divided into 3 subgroups respectively as toothbrush and toothpaste/soap, denture cleansing tablets and sodium carbonate, and 3 times a day, everyday, every 3 day and once a week. The data obtained was evaluated by One-way ANOVA, Mann-Whitney U-test, Kruskal-Wallis-test, Student t-test and chi(2)-test. The level of statistical significance was set at p<0.05. The patients displayed statistically significant differences in the topics of the length of time of denture usage and the balance of denture in terms of retention. The complete denture wearers should be educated in the importance of periodic examination due to the changing of supporting tissues for detection early mucosal lesions to maintain their oral and dentures hygiene in optimum level.

Satisfaction of the complete denture wearers related to various factors.

All dentists who have worked with complete denture wearers know that patient satisfaction is not based only on the technical quality of the dentures. The aim of this study was at assessing the effect of gender, the number of the dentures used before, the length of time of denture usage, education and age on the satisfaction of the complete denture wearers. The students of the Dental Faculty of Marmara University (Turkey) made new dentures for 342 patients who were asked to participate in the investigation. The subjects (137 men and 205 women) were 39-89 years of age with a mean of 61.62 years. The attitude toward dentures in general was measured by means of 11 items of a questionnaire. The 10 main questions of the questionnaire were answered by the participants, and quantified on a 7-point scale, while the 11th issue (general satisfaction) was evaluated on a scale of 1-10. All main factors were also estimated in subgroups. For example, the education was analyzed in 4 subgroups, the time of denture usage was divided into two subgroups (below and above 3 years) and the number of dentures used before was also taken as up to 3 or more than 3 dentures. The age of the subjects was taken in 3 subgroups: 40-55, 56-65 and >65 years. One-way ANOVA, Tukey and Student t-tests were used to evaluate the answers to the questionnaire. Our patients displayed statistically significant differences only in the topics of their ability of cleaning their dentures, due to education and number of previously used dentures.

The study of the age of becoming edentulous in the last 20 years in Turkey.

The aim of this study was to determine the age of becoming edentulous and make a comparison between the patients examined in 1987 and in 2007 at the Dental School, University of Marmara in Istanbul, Turkey. A total of 680 patients (336 in 1987 and 344 in 2007) visiting the Dental School were examined. Some of the patients had just their teeth drawn, or had already became edentulous before, and were sent to the Department of Prosthodontics, for prosthodontic treatment of their edentulous mandible or maxilla. Some of the patients have few teeth and they were extracted at the Department of Oral and Maxillofacial Surgery, they became edentulous. The age of the patients that they first become edentulous and begin to use complete denture was determined. The patients grouped according to their age, sex and being completely edentulous or edentulous in one jaw. Fisher's exact test was performed during the evaluation of quantitative data. Statistical significance level was established at p<0.05. Between 1987 and 2007, a more than 50% decrease was observed in the number of the patients who were completely edentulous or edentulous only in one jaw. This observation is one of the indications of development of patients' care and improvement in the state of mouth health in Turkey during the last 20 years.

Replacement of a maxillary central incisor using a polyethylene fiber-reinforced composite resin fixed partial denture: a clinical report.

Fiber-reinforced composite resin (FRC) restorations generally consist of a composite resin veneer supported by a fiber-reinforced composite resin substructure and prepared chairside to be used when the patient needs a short-term solution. It is an esthetic, conservative treatment alternative and allows for future options. This article describes the use of a polyethylene fiber-reinforced composite resin fixed partial denture (PFRCFPD) with a ceramic pontic for the replacement of a missing central incisor due to trauma.

Posterior maxillary segmental osteotomy for restoring the mandible with dental implants: a clinical report.

Posterior segmental collapse causes narrowing of interarch space and prevents adequate restoration in the posterior quadrant. Posterior maxillary segmental osteotomy (PMSO) is an alternative option that enables prosthodontic restoration with an implant-supported fixed partial denture. The following clinical report describes prosthodontic rehabilitation with fixed prostheses after a posterior maxillary segmental osteotomy for a patient with a partially edentulous mandible.
