Statement of problem: With the aging population, an increasing number of patients will require removable dental prostheses. Despite the recent public efforts to improve oral healthcare, knowledge of hygiene procedures for removable dental prostheses is sparse. Purpose: The purpose of this cross-sectional study was to determine, through questionnaires, the level of awareness and education of home hygiene procedures among elderly Italian individuals wearing removable dental prostheses and to correlate self-reported hygiene habits and prosthesis cleanliness, as determined by a clinical examination. Material and methods: A cross-sectional study was performed by questionnaires administered by a dental hygienist to patients attending the dental clinics (prosthodontic and periodontology clinical units) at San Paolo Hospital of Milan from January 2014 to October 2015 and who volunteered to participate. The questionnaire included demographic data and oral hygiene habits. Each participant received an intraoral and prosthesis examination performed by the same dental hygienist. The cleanliness of the removable dental prosthesis was classified according to a 3-point scoring system. Categorical variables were expressed as a percentage of study participants and compared by using the χ2 test, while, for the statistical correlations between continuous and categorical variables, the point-biserial correlation calculator was used (α=.05). Results: Questionnaires were collected from 161 study participants: 92 women (mean ±standard deviation age: 76 ±7.59 years; range: 65-93 years) and 69 men (mean ±standard deviation age: 74 ±6.31 years; range: 65-86 years). A total of 239 prostheses were considered. A significant correlation was found between older participants, older removable dental prostheses, and reduced prosthesis cleanliness, correlating age ranges of participants as well as of removable dental prostheses with the degrees of prosthesis cleanliness (P=.001 and P=.004, respectively). Half the study participants (n=81; 50.3%) reported prosthesis removal during the night, while the others reported sleeping with the prosthesis in place. Some study participants (n=32; 19.9%) reported that they had never received instructions about how to clean the prosthesis. Mechanical brushing with toothbrush and toothpaste was the most common cleaning method (n=47; 29.2%), while the recommended combined cleaning method based on both mechanical brushing and immersion in dental cleanser was applied by 34 (21.1%) study participants. A similar number (n=25; 15.5%) reported at least 1 episode of denture-related stomatitis. Conclusions: In the analyzed cohort, patient attitude and habits toward home procedures for denture hygiene resulted in poor prosthesis cleanliness. Most individuals used a toothbrush and toothpaste to clean their device, although combining mechanical and chemical cleaning is typically reported to be the optimal method.

Abstract

Statement of problem: With the aging population, an increasing number of patients will require removable dental prostheses. Despite the recent public efforts to improve oral healthcare, knowledge of hygiene procedures for removable dental prostheses is sparse. Purpose: The purpose of this cross-sectional study was to determine, through questionnaires, the level of awareness and education of home hygiene procedures among elderly Italian individuals wearing removable dental prostheses and to correlate self-reported hygiene habits and prosthesis cleanliness, as determined by a clinical examination. Material and methods: A cross-sectional study was performed by questionnaires administered by a dental hygienist to patients attending the dental clinics (prosthodontic and periodontology clinical units) at San Paolo Hospital of Milan from January 2014 to October 2015 and who volunteered to participate. The questionnaire included demographic data and oral hygiene habits. Each participant received an intraoral and prosthesis examination performed by the same dental hygienist. The cleanliness of the removable dental prosthesis was classified according to a 3-point scoring system. Categorical variables were expressed as a percentage of study participants and compared by using the χ2 test, while, for the statistical correlations between continuous and categorical variables, the point-biserial correlation calculator was used (α=.05). Results: Questionnaires were collected from 161 study participants: 92 women (mean ±standard deviation age: 76 ±7.59 years; range: 65-93 years) and 69 men (mean ±standard deviation age: 74 ±6.31 years; range: 65-86 years). A total of 239 prostheses were considered. A significant correlation was found between older participants, older removable dental prostheses, and reduced prosthesis cleanliness, correlating age ranges of participants as well as of removable dental prostheses with the degrees of prosthesis cleanliness (P=.001 and P=.004, respectively). Half the study participants (n=81; 50.3%) reported prosthesis removal during the night, while the others reported sleeping with the prosthesis in place. Some study participants (n=32; 19.9%) reported that they had never received instructions about how to clean the prosthesis.
