In order to collect some necessary data to promote correcting the toothbrushing technic on the Korean public, the author had examined the number of present teeth on which had cervical abrasion and the most basic home dental care in 2,000 Korean male and female adults from 19 to 52 years in the age. Then, the cervical abrasion experience rate and the cervical abrasion experience teeth rate were calculated and evaluated.
The obtained results were as follows:
1. Cervical abrasion experience rate was 32.45%
2. Cervical abrasion experience rate was gradually increased by ageing.
3. Cervical abrasion experience rate in male adults was higher than that in female adults.
4. Cervical abrasion experience rate in the lower jaw was higher than that in the upper jaw.
5. Cervical abrasion experience rate of the teeth at the right side was higher than that of the teeth at the left side.
6. Cervical abrasion experience teeth rate was 3.82%.
7. Cervical abrasion experience rate was highest on the first bicuspid, and followed in the sequence of the second bicuspid, canine, first molar, incisors, and 2nd and 3rd molars. |
