Self-reported denture hygiene habits and oral tissue conditions of complete denture wearers

The aim of the study was to examine the influence of denture hygiene on the development and intensity of denture stomatitis and traumatic ulcers and their relationship to age, gender, educational level, smoking status, age of the denture, denture hygiene habits and denture-wearing behavior. The study population comprised 310 complete denture (CD) wearers (159 males and 151 females) aged 60-85 living in Kirikkale, Turkey. Denture hygiene habits were assessed and recorded, and any relationships between denture hygiene habits and the condition of oral tissue were assessed. The majority (48.4%) of participants reported cleaning their dentures with a toothbrush and toothpaste and 45.2% with a toothbrush only. Less than half (44.8%) removed their dentures overnight. Stomatitis was observed in 35.8% and traumatic ulcers in 29% of patients. A positive relationship was observed between poor denture hygiene habits and the presence of denture-related stomatitis and traumatic ulcers. The degree of denture hygiene was significantly associated with age, sex, education, general health status, smoking status, self-perception of halitosis, overnight denture removal and denture immersion habits.

KRON-KÖPRÜ RESTORASYONLARINDA SEKONDER ÇÜRÜĞÜN RADYOLOJİK VE KLİNİK OLARAK DEĞERLENDİRİLMESİ

The aim of this study was to evaluate the results of visual assessment of teeth restored with crowns or fixed partial dentures with the outcome of the radiographic evaluation and evaluate the inter observer agreement. Ninety three randomly selected patients who underwent restorations with fixed prostheses were included in the study. A total of 372 restorations (228 interproximal surfaces of 114 single crowns and 516 interproximal surfaces of 258 fixed partial denture retainer crowns) were investigated by two observers clinically, with the use of the criteria modified by Zoellner et al, and radiographically for interproximal carious lesions. The extension of the lesions was rated to be initial (with no cavitation), early (with cavitation limited to orthodentin), or deep (with cavitation). Statistically significant differences were determined by use of the Pearson’s chi square test (P<.05). The diagnostic accuracy of the radiographic surveys and clinical examination for secondary caries was assessed by means of ROC (Receiver Operating Characteristics) curve analysis. Kappa analysis was used to determine the inter observer agreement. In this study there were statistically significant differences between secondary caries and age, DMFT, DMFS, longevity of restorations and type of the material used were statistically significant (p<0.01). The areas under the ROC curve for panoramic survey, bitewing survey and clinical examination regarding secondary caries was respectively 0.932, 0.991, 0.988 for Observer A and 0.916, 0.984, 0.979 respectively for Observer B. The interobserver agreement was substantial for clinical evaluation (κ= 0.680) and panoramic survey (κ= 0.720) and almost perfect for bitewing survey
