The Association between Dental Implant Treatment Experience and Socioeconomic Factors in Korean Adults: A Cross-Sectional Survey Data Analysis.

Background: We examined the Korean adults' experience with dental implants and analyzed its association with various socioeconomic factors.

Methods: This study was based on the participants enrolled in the 2013-2015 KNHANES. Using the variables associated with dental implant treatment experience and other socioeconomic factors, we evaluated the statistical significance and potential associations between the dental implant treatment experience and its related factors.

The impact of national health insurance coverage on pit and fissure sealing experience.

Introduction: The purpose of this study was to review the change of supplied amount of oral pit and fissure sealing (PFS) in urban and rural areas of South Korea after including PFS into the list of treatments covered by the National Health Insurance (NHI), and to check whether there is a difference in supplied amount in areas where the dental treatment accessibility is different based on the data of the Korean National Health and Nutritional Examination Survey (KNHANES).

Methods: The KNHANES data year used for 'before coverage' was 2007, and that of 'after coverage' was 2012. Data analysis was done using STATA software.

Oral healthcare systems for an ageing population: concepts and challenges.

Oral healthcare systems (OHCS) are designed to maintain the health and function through Communication (Health promotion and education), Prevention, Assessment and Diagnosis, and Treatment. The complexity of these OHCS functions for the ageing are described utilizing the spectrum of dependency of the Seattle Care Pathway framework. Barriers and disparities which challenge the development of OHCS for the ageing can be universal but often vary between developed and developing countries.

Systemic effect of water fluoridation on dental caries prevalence.

Objectives: The aim of this study was to evaluate the systemic effect of water fluoridation on dental caries prevalence and experience in Cheongju, South Korea, where water fluoridation ceased 7 years previously.

Methods: A cross-sectional survey was employed at two schools where water fluoridation had ceased (WF-ceased area) and at two schools where the water had never been fluoridated (non-WF area). The schools in the non-WF area were of a similar population size to the schools in the WF-ceased area.

Global self-rating of oral health, concerns about oral health, and history of jaw injury related to temporomandibular joint symptoms in Korean adults.

Aims: To examine the association between temporomandibular joint (TMJ) symptoms and the global self-rating of oral health, concerns about oral health, and a history of jaw injury or third molar extraction in a representative Korean population.

Methods: From the Korean National Oral Health Survey 2006, 4,546 adults aged 18 years and older were included in the analysis. The dependent variable was TMJ symptoms.

The decline in dental caries among children of different ages in Korea, 2000-2006.

Aim: To determine the prevalence of dental caries in Korean children with time after the introduction of the nationwide public oral health programme.

Design: Cross sectional oral health surveys of children aged from 6-16 years carried out in 2000 and 2006.

Participants: After stratified cluster sampling, 11,947 (2000) and 9,740 (2006) children aged 6-16 years of age were examined at school.

Validation of the Korean version of the oral health impact profile among the Korean elderly.

Objectives: This study aimed to validate a Korean version of the oral health impact profile (OHIP) and to develop a short-form of OHIP for the Korean elderly.

Methods: The original English version of OHIP was translated into Korean using a forward-backward method. Internal consistency was measured by Cronbach's alpha among 1098 subjects aged 56 or more.

Effects of two preparation designs and pontic distance on bending and fracture strength of fiber-reinforced composite inlay fixed partial dentures.

Statement Of Problem: Joint fractures observed in Targis/Vectris inlay adhesive fixed restorations may be related to the preparation design.

Purpose: This in vitro study investigated the effects of the proximal tooth preparation design and the pontic distance on the fracture strength and the amount of bending of fiber-reinforced inlay adhesive fixed partial dentures.

Materials And Methods: Forty extracted premolars and 40 molars were embedded in a PMMA resin to represent a premolar and molar mesiodistal separation distance of 7 mm and 11 mm, respectively.
