Abstract

BACKGROUND AND AIM: Perception of the need for oral healthcare plays a key role in creating motivation and demand for utilization of oral healthcare services. Furthermore, while the lack of resources, people with perceived needs to oral healthcare, due to the higher profit potential of services, will be on higher priority for services. The aim of this study was to undertake a systematic review of the existing literature about questionnaires used for assessing the perceived oral healthcare needs.METHODS: The search was conducted in PubMed, ISI and Scopus databases in March 2016. Questionnaire-based and the papers which aimed to determine the perceived need for any type of oral healthcare and dental treatment were included to this study. After determining the appropriate papers, related data were extracted and reviewed.RESULTS: Out of 7069 records found, 190 questionnaire-based papers were included in the review. Ninety-four papers were related to the overall evaluation of oral healthcare need, which did not ask the need for types of oral healthcare service. Sixty-six papers studied the need for a specified dental service, and thirty papers recorded the types of oral healthcare service via asking the open or multiple choices questions. There were not comprehensive and standard questionnaires covering all the common types of oral healthcare services.CONCLUSION: Despite the importance of considering the perception of needs for oral healthcare, there is a lack of the comprehensive and standard questionnaires. Studies aimed to assess perceived oral healthcare needs should use questionnaires which include appropriate items on common types of oral healthcare services based on the characteristics of the target group. Concordance with perceived and normative need is an issue that should be addressed in future researches.
