Investigating the Prevalence of Dental Caries and its Relationship with Oral and Dental Quality of Life in Thalassemia Patients According to the ICDASII Index

Abstract

Introduction and Aim: Several factors affect the oral and dental-related quality of life. The present study investigates the effect of the prevalence of dental caries and its relationship with oral and dental quality of life in thalassemia patients according to the ICDASII index.

Methods: The present study was a cross-sectional analysis. The statistical population of the study consisted of 132 thalassemia patients who were selected and included in the study through convenience sampling in Kermanshah. Data collection tools included a demographic information form, ICADS index, and oral and dental health-related quality of life questionnaire. Data were analyzed in SPSS 25 software using descriptive statistics, correlation tests, and linear regression at a significance level of 0.05.

Results: According to the results, the mean quality of life score was 38.9 ± 8.8. The results of Pearson's correlation test revealed a direct and significant correlation between the total score of oral and dental quality of life and the ICADSⅡ index (P<0.05, r=0.564). There was no significant correlation between the gender and age of patients and the ICADSⅡ index (P<0.05).

Discussion and Conclusion: Dental caries evaluation using the ICDASII system provides accurate recommendations for prevention and correct treatment. The severity and degree of caries in thalassemia patients were relatively high. A low quality of life score indicates an unfavorable oral and dental quality of life. Thalassemia patients have more severe problems than healthy people. Hence, the provision of services, care, and periodical examinations should be improved in these patients.
