This oral health education program was effective in establishing good oral health habits among preschool children and in increasing oral health knowledge of their parents, in conjunction with supervised daily tooth brushing with fluoridated toothpaste, which could reduce the development of new dental caries in preschool children in China.

A massive campaign on "Love Teeth Day" (LTD) has been celebrated nationwide each year in China since 1989. As announced in an official document, nine government and non-government organizations have jointly issued a circular designating that the 20th of September of each year be kept for the Love Teeth Festival in this country. The main activities were planned and conducted by the National Committee for Oral Health, which was set up in 1988. It aims to motivate the people's awareness of dental self-care, participation, and to promote community involvement in oral health education programs. For feedback, two types of questionnaires were designed and sent to the public and the organizers, respectively, after each campaign, and then returned to the office for data processing. The findings from a four-year study indicated that: (1) The activities started from three municipalities, 29 capitals of provinces, and some large cities (1989), and spread to most cities in the urban area, and about 300 counties in the rural area (1992); (2) 14,000 dental professionals and health workers participated in 1989 as information providers, and increased to 40,000 in 1992; (3) oral health knowledge has increased to 76.2% (1992) from 37% (1989); and (4) the people's will in dental prevention was strengthened.

The consumption of fluoridated milk by the kindergarten children in Beijing was an effective measure in preventing caries in the primary teeth.

The aim of the study is to investigate the feasibility of milk fluoridation as a vehicle for caries prevention, based on the current epidemiological status and its trends of dental caries in preschool children in the area of the Haidian District of Beijing, where the indications exist: Fluoride level in drinking water is low (0.2-0.3 ppm), and water fluoridation and other systemic uses of fluorides are unlikely. From 75.9 to 79.7% of 3-6-year-old children were identified as having high caries experience (dmft 4.29-4.35). It was found that 60% of the preschool children who attended kindergarten were 3-6 years old, and 40% of the 1-2-year-olds were living with their families. There is a local dairy to produce milk for the population living in this district. The amount of fresh milk produced daily is about 50,000-60,000 kg. A special kind of milk with vitamins A and D is also available for the preschool children. Data available from the Community MCH Centre indicated that the percentage of breast-feeding is 12% only. The first choice by parents for artificial feeding to the babies is fresh or powdered milk. Therefore, the breast-feeding project started in 1992. It is recommended that mothers' milk should be provided to the babies for at least four months after birth, when a specially prescribed milk for the babies, produced by the dairy, will be provided on a daily basis. The cost of milk is cheaper than others. In this connection, a five-year project on milk fluoridation as a pilot study at the community level for caries prevention of preschool children is now planned. The project is supported by BDMF, WHO, and Chinese MOPH.

It is widely acknowledged that the development of new media has imposed a significant influence on the traditional-media-based society, but how? This paper focuses on the multi-dimensional impact of the rise of new media on the modern society which is based on traditional media. This work is investigated from four different directions: reduced public's trust in the media, acceleration of the spread of fake news, increase in political polarization and anti-government attributes of media responses, and the replacement of traditional media in commercial promotion. The research supports each viewpoint with specific social examples and comes to the conclusion that people's opinions are more easily controlled by the media. Finally, this paper calls for more research on how people could maintain their independence of thought in the face of new media and use new media to benefit mankind.
