人进入老年后,机体的各种器官都在发生着变化。口腔组织也会随年龄的增长而变化。除机械性损伤,如牙齿磨耗之外,更重要的是会产生退行性改变,如脱钙、血管硬化、牙槽骨吸收、牙龈萎缩、唾液腺分泌减弱等等。正是由于老年人的这种不可抗拒的变化,使得老年人的牙齿保健更具有重要意义。 When people enter old age, various organs of the body are undergoing changes. Oral tissue also changes with age. In addition to mechanical damage, such as tooth wear, more importantly, degenerative changes such as decalcification, hardening of the arteries, alveolar bone absorption, gingival recession, diminished secretion of salivary glands, and the like are all the more important. It is precisely because of this irresistible change in the elderly, making older people's dental care more important.
