树脂用于修复术虽已多年,但直到近年来才被引用于预防口腔医学。用树脂封填点隙、沟裂,虽然只代表了龋病预防的一个方面,但作为一种预防措施,其占据的位置已相当突出。封填点隙、沟裂的基本原理,是基于上述区域有高度的易感性。龋病的进程,尤其在第一、二磨牙,通常是在萌出后不久即发生,且进展快而往往导致失牙。Knudsun等在4,416名初小学生的调查中发现,恒牙(牙合)面龋占所有龋及充填面的43%,是为典型的好发部位。Day等的报告进一步证实,在13岁儿童的恒牙中,有45%的龋累及(牙合)面,上述观察具有特殊意义,因为在该年龄组,(牙合)
Although resin has been used for many years in repair, it has not been cited in the prevention of stomatology until recent years. Filling point gaps with resin, fissures, while representing only one aspect of caries prevention, but as a precautionary approach, its position has been quite prominent. Filling point gap, the basic principle of crack, is based on the above-mentioned area has a high degree of susceptibility. The process of caries, especially in the first and second molars, usually occurs shortly after eruption and progresses rapidly and often leads to tooth loss. In a survey of 4,416 primary school students, Knudsun et al. Found that permanent dental caries accounted for 43% of all caries and filling surfaces and was a typical predilection site. The report by Day et al further confirms that 45% of the permanent teeth in a 13-year-old child have occlusal surfaces and that this observation is of special significance because in this age group,
