Evaluation of an Oral Health Management Project in Connection to a Non-Communicable Disease Prevention and Management Project: A Case Study in South Korea.

This study aimed to develop, pilot, and evaluate a three-year integrated preventive management project focused on chronic diseases and oral health prevalence. A total of 1148 users of the health care office of the G Public Health Center with dental risk factors were selected for this study and connected to the dental counseling department. Respondents were classified into a group that would receive counseling-type self-education on oral care and a second group that needed dental care.

Did Expanded Dental Insurance Reduce Out-of-Pocket Expenditures on Dental Care among Older Adults in Korea? Interrupted Time-Series Analysis.

The Korean National Health Insurance extended its coverage to reduce the economic burden of receiving dentures and implants for older adults in 2012 and 2014, respectively. We examined whether the new policy resulted in reduced out-of-pocket dental care expenditure in the eligible population, specifically focusing on low-income adults. We used interrupted time-series analysis (ITSA), a quasi-experimental design, to identify the effects of the policy among persons aged 65 or older.

The Impact of Expanded National Health Insurance Coverage of Dentures and Dental Implants on Dental Care Utilization among Older Adults in South Korea: A Study Based on the Korean Health Panel Survey.

(2) Methods: The data were applied from the first national survey for homeless people in South Korea, 2016.

Did the extended coverage policy contribute to alleviating socioeconomic inequality in untreated dental caries of both children and adolescents in South Korea?

Background: Dental sealants have been covered by the National Health Insurance Service (NHIS) since December 2009 in South Korea. This study aims to determine whether the socioeconomic inequality in untreated dental caries decreased after implementing the extended coverage policy for dental sealant.

Methods: The data were derived from the fourth (2007-2009) and sixth (2013-2015) waves of the Korean National Health and Nutrition Examination Survey (KNHANES) conducted by the Korea Centers for Disease Control and Prevention (KCDC).

Inequalities in oral health among adolescents in Gangneung, South Korea.

Background: This study aims to evaluate inequality in oral health among adolescents and to explain the mechanisms of such inequalities in Gangneung, South Korea.

Methods: One thousand two hundred sixty-seven students in their first year from four vocational and three general schools participated in the baseline survey of 2011, and 84.7% of them were surveyed again in 2013.

Which life course model better explains the association between socioeconomic position and periodontal health?

Aim: To assess whether the relationship between socioeconomic position (SEP) and periodontal health fitted the Critical Period or the Social Mobility life course models.

Methods: A nationally representative sample of 5570 Korean adults from KNHANES IV study. Log-binomial regression models adjusting for adulthood or childhood socioeconomic (SES) variables was used to assess independent effects of socioeconomic differences for childhood, adulthood and period of transition from child to adult in periodontal health.

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.

Functional analysis of the extended N-terminal region in PLC-δ1 (MlPLC-δ1) from the mud loach, Misgurnus mizolepis.

Mud loach phospholipase C-δ1 (MlPLC-δ1) contains all the characteristic domains found in mammalian PLC-δ isozymes (pleckstrin homology domain, EF-hands, X–Y catalytic region, and C2 domain) as well as an extended 26-amino acid (aa)-long N-terminal region that is an alternative splice form of PLC-δ1 and is novel to vertebrate PLC-δ. In the present structure-function analysis, deletion of the extended N-terminal region caused complete loss of phosphatidylinositol (PI)- and phosphatidylinositol 4,5-bisphosphate (PIP2)-hydrolyzing activity in MlPLC-δ1. Additionally, recombinant full-length MlPLC-δ1 PLC activity was reduced in a dose-dependent manner by coincubation with the 26-aa protein fragment.

Intraocular lens power calculations for cataract surgery after phototherapeutic keratectomy in granular corneal dystrophy type 2.

Purpose: To investigate the predictability of various intraocular lens (IOL) power calculation methods in granular corneal dystrophy type 2 (GCD2) with prior phototherapeutic keratectomy (PTK) and to suggest the more predictable IOL power calculation method.

Methods: Medical records of 20 eyes from 16 patients with GCD2, all having undergone cataract surgery after PTK, were retrospectively evaluated. Postoperative cataract refractive errors were compared with target diopters (D) using IOL power calculation methods as follows: 1) myopic and 2) hyperopic Haigis-L formula in IOLMaster (Carl Zeiss Meditec); 3) SRK/T formula using 4.

Extremely varied phenotypes in granular corneal dystrophy type 2 heterozygotes.

Purpose: To investigate the phenotypic variability of patients bearing the heterozygous R124H mutation in the TGFBI (transforming growth factor-beta-induced) gene that causes granular corneal dystrophy type 2 (GCD2).

Methods: We describe the phenotypic range of GCD2 heterozygotes for the common R124H mutation in TGFBI; seven with an extremely mild phenotype and six with an extremely severe phenotype. Detailed slit-lamp photographs of these patients were generated.

Phototherapeutic keratectomy in diffuse stromal haze in granular corneal dystrophy type 2.

Purpose: To determine the minimum depth of phototherapeutic keratectomy (PTK) required for diffuse haze removal in granular corneal dystrophy type 2 and to determine whether Fourier domain optical coherence tomography (FD-OCT) can be an effective technique for predicting the exact required depth of ablation.

Methods: The depth of ablation used for diffuse stromal haze removal was evaluated with the slit lamp and serially taken photographs during the PTK procedure. The depth of diffuse haze was measured preoperatively using FD-OCT.
