Purpose:
To investigate the category and prevalence rate of denture-related oral mucosal lesions (DML) in 185 patients with removable denture and analyze the influencing factors.
Methods:
A total of 185 patients with removable denture who visited the department of stomatology of our hospital from October 2015 to June 2018 were investigated by questionnaire. DML types and locations were recorded in detail, and patients were followed up after treatment. Based on the data of this study, the differences of DML reports in other regions of China were analyzed by comparing the results searched from databases. SPSS 17.0 software package was used for statistical analysis.
Results:
In this study, the DML prevalence rate was 42.7%, significantly higher in male patients than in female patients (54.17% vs 35.40%, P<0.05). DML was more common in complete denture wearers than that in partial denture wearers (66.67% vs 31.20%, P<0.05). The categories of DML were as followed (prevalence rate from high to low): denture stomatitis (54.43%), traumatic ulcer (34.18%), inflammatory hyperplasia (6.33%), and angular cheilitis (5.06%).
Conclusions:
DML is affected by multiple factors. Among them, denture related factors include denture type, denture wearing time, denture lasting time and cleaning method. DML is more influenced by the type of denture than the wearing time. Gender, ethnicity and systemic diseases may affect the prevalence of DML, but further studies are needed. The results of domestic studies in various regions cannot objectively reflect the current prevalence rate of DML, thus a multi-center epidemiological investigation is needed.
