다국어 초록 (Multilingual Abstract)

Along with toothbrushes, toothpaste has been used for a long time to improve the personal oral hygiene. Toothpaste was firstly introduced to Korea through as a form of powder by the Japanese company Lion Corporation in 1889 and in 1954, the LakHee Chemistry company released Korea’ s first ever tube type cream toothpaste called lucky toothpaste, and afterwards we got to where we are today in terms of toothpaste. As a variety of products are released and customer choices become more diverse, there needs to be a development of toothpaste that can fulfill customers’ needs and requests. Therefore, this study analyzes toothpastes and related patents submitted to the Patent Office from 1962 to June 2015, thereby examining the changes in toothpaste development trends up to the present day. This study was searched using the keyword ‘toothpaste’ in the patent, utility model search engine at Kipris(www.kipris.or.kr), a patent search site, and categorized a total of 2,465 patents, which excluded those rejected by the Patent Office and those unrelated to toothpaste, using titles, full texts of publications and announcements. Research results showed that in the past, from 1960 to 1989, patents related to toothpaste containers took up the highest ratio of 35%. However, after 1990, patents pertaining to toothpaste composites and functionality made up the highest percentage of 54%, and from 2010 to 2015, it occupied 72% of the whole; therefore, we analyzed in detail the patents related to composites and functionality. Taking a look at the objectives and effects of patents having to do with composites and functionality, we found out that from 1964 to June 2015, patents related to Base, a basic component of toothpaste, and those having to do with periodontal disease took up the highest percentages of 25% each, and from 2010~2015 in particular, patents concerning periodontal diseases were submitted 3% more than those about Base. Composites aiming to prevent and treat periodontal diseases can be divided into four different categories, based on components; among those, there were a total of 171 (57%) patents related to living organism and herbal medicine extracts, 107 (36%) patents using compounds, 16 (5%) patents using bamboo salt as well as salt, and 5 (2%) patents using mineral components such as gold, silver. Looking at these investigation results, it can be thought that with the increasing development of toothpaste related to periodontal diseases, there’ s a great amount of interest about toothpaste of effective periodontal disease prevention and treatment purposes. Along with this, we thought that research about how effective periodontal disease toothpastes actually are is also necessary.
