Objectives: This study analyzes the demands of dental hygiene college students for English courses and proposes ways to improve English courses for college students majoring in dental hygiene that would take advantage of English for specific purposes (ESP) in the future. Methods: Using a structured questionnaire, four universities by region with departments of dental hygiene were selected at random, and out of a total of 260 college students majoring in dental hygiene, data of 258 students, excluding data with missing values, were considered for investigating the needs of English curriculum development using the SPSS program. Results: Total 82.1% of the students expected English programs, and they said that English was important, The proposal for English curriculum development indicated that although the number of English programs was sufficient, diversification of English programs or changes in methods of managing classes were required. As for the need for English programs (66.4%), they required more ESP, such as practical English for dental or dental terminology, which can be used clinically and more than English for general purposes (EGP). Conclusions: Students in dental hygiene showed a higher demand for more professional ESP that can use clinically as dental hygienists in the future. It is necessary to consider the reorganization of the curriculum or changes in the method of managing English classes by reflecting one demands of dental hygiene students.

Objectives : The purpose of this study was to make a comparative analysis of the websites of dental office from different countries to provide some information for the quality evaluation of the websites of dental office. Methods : Two hundred twenty-four dental websites were selected by using Yahoo, one of the international portal sites, which included 59 from the United States, 50 from the United Kingdom, 54 from Canada, and 61 from Korea. Results : 1. As results of the credibility of the websites, the Canadian websites were most reliable, followed by the American websites, the English websites and the Korean ones(p<0.005). 2. As results of the complementarity of the websites, the Korean websites were most interactive, followed by the American websites, the English websites, and the Canadian ones(p<0.001). 3. As results of the accessibility of use of the websites, the Korean websites were easiest to use, followed by the American websites, the Canadian websites, and the English ones(p<0.001). 4. As results of the update of the websites from the nations, the Korean websites were most sustainable, followed by the English websites, the Canadian websites and the American ones(p<0.05). 5. When the overall quality of the dental office websites was assessed, the Korean websites were the best, followed by the Canadian websites, the American websites and the English ones(p<0.001). Conclusions : In order to make accurate oral health information more accessible to people in general, prolonged research efforts should be continued for the evaluation of the quality of dental office websites, and the development of standard international evaluation criteria is required as well.

Using EPG, the stop and fricative portions of the Korean and English afficates were examined to find out whether the stop and fricative portions of Korean affricates are the same as those of English ones in articulation, as generally assumed in the literature. The English affricate in the word 'choose' is classified as alveopalatal just like the Korean affricate in the word 'cam'. The results of the EPG data showed that Korean affricates were not articulated the same as those in English, especially in the stop portion. In English, the stop portion of 'choose' was quite similar to /t/ as 'tooth', but in Korean, the stop portion of 'cam' was somewhat different from /t/ in 'tam'. More specifically, the stop portion of /t/ in 'tam' was articulated with the contact at the upper teeth and the alveolar ridge, but the stop portion of /t/ in 'cam' was articulated with the contact in the alveopalatal region. This shifting in the place of articulation of the stop portions of the Korean affricate (from dental and alveolar to alveopalatal) can be explained. Unlike English affricates, the stop portions of Korean affricates and the fricative portions of Korean affricates are co-articulated at the same place of articulation.

The objective of this review was to investigate the efficacy of dental local anesthetics, as it is well known among clinicians that local anesthesia may be challenging in some circumstances. Therefore, the focus of this review was on the efficacy of the products used in dental local anesthesia. In a Pubmed database literature search conducted, a total of 8646 articles were found to be related to dental local anesthetics. After having applied the inclusion criteria (human research, performed in the last 10 years, written in English language, and focus on dental local anesthetics) and having assessed the quality of the papers, 30 were deemed eligible for inclusion in this review. The conclusion of this review is that none of the dental local anesthetic amides provide 100% anesthesia. The problem appears to be more pronounced when mandibular teeth are attempted to be anaesthetized and especially if there is irreversible pulpitis involved. The authors conclude that this finding suggest exploration of more efficient techniques to administer dental local anesthesia, especially in the mandible, to establish a 100% efficacy, is needed.

Purpose: With the popularity of implant therapy, clinicians need to know about treating the dental implant in patients with gingival involvement of oral lichen planus (OLP). The aim of this study is to evaluate the survival and success rates of dental implant and propose of clinical guidelines for implant treatment in OLP patient with gingival involvement. Methods: A literature search was performed in PubMed/Medline, and Cochrane database. Papers in English language published between 1990 and 2019 were evaluated. The focused questions were following; 1) Dose gingival OLP affect the survival and success rates of dental implants? 2) The management of OLP patients with gingival involvement receiving dental implant. Results: There was no study about the evaluation of dental implant only in gingival OLP patient. Five studies evaluating dental implants in OLP patients were included in this review. Implant survival rate was 100.0% in well-controlled OLP patients in all included studies. The use of topical/systemic corticosteroid in OLP patients was performed before and/or after implant placement in all included studies. Conclusions: The implant survival and success rates in well-controlled OLP patients did not different from that of non-OLP healthy subjects. The gingival OLP is associated with higher rate of peri-implant mucositis. Adequate management of gingival OLP lesions before and after implant insertion is required to reduce inflammation and associated bone loss.
