The aim of this study was the quantification of alveolar bone resorption as well as the number and percentage of teeth with dental caries.
Four samples of jaws and single teeth were studied from four time periods, i.e. from the Krapina Neanderthals (KN) who reportedly lived over 130,000 years ago, and groups of humans from the 1(st), 10(th) and 20(th) centuries. Resorption of the alveolar bone of the jaws was quantified by the tooth-cervical-height (TCH) index. Diagnosis of dental caries was made by inspection and with a dental probe. TCH-index was calculated for a total of 1097 teeth from 135 jaws. Decay was calculated for a total of 3579 teeth.
Resorptive changes of the alveolar bone in KN and 1(st) century man were more pronounced on the vestibular surface than interdentally (p<0.05), while no significant difference could be confirmed for 10(th) and 20(th) century man (p=0.1). The number (percentage) of decayed teeth was 0 (0%, n=281 teeth) in KN, 15 (1.7%; n=860 teeth) in 1(st) century, 24 (3.4%; n=697 teeth) in 10(th) century, and 207 (11.9%, n=1741 teeth) in 20(th) century.
On the basis of our results it may be postulated that in contemporary man in relation to KN, the accumulation of plaque pathogens in the interdental space is substantially greater than on the vestibular side. These findings have practical, educational and preventive value for oral hygiene improvement, especially of the interdental space, which should help decrease the prevalence of periodontal disease and dental caries, and improve oral as well as general health.
本研究旨在量化牙槽骨吸收情况以及患龋牙齿的数量和百分比。
研究了来自四个时间段的四个颌骨和单颗牙齿样本,即据报道生活在13万多年前的克拉皮纳尼安德特人(KN),以及来自1世纪、10世纪和20世纪的人类群体。通过牙颈高度(TCH)指数对颌骨牙槽骨的吸收情况进行量化。通过检查和使用牙科探针进行龋齿诊断。计算了来自135个颌骨的总共1097颗牙齿的TCH指数。计算了总共3579颗牙齿的龋齿发生率。
KN和1世纪人类牙槽骨的吸收变化在前庭表面比牙间隙处更明显(p<0.05),而10世纪和20世纪人类未证实有显著差异(p=0.1)。患龋牙齿的数量(百分比)在KN中为0(0%,n=281颗牙齿),在1世纪为15(1.7%;n=860颗牙齿),在10世纪为24(3.4%;n=697颗牙齿),在20世纪为207(11.9%,n=1741颗牙齿)。
根据我们的研究结果,可以推测与KN相比,当代人类牙间隙中菌斑病原体的积累比前庭侧要多得多。这些发现对改善口腔卫生具有实际、教育和预防价值,尤其是对牙间隙的卫生改善,这应有助于降低牙周病和龋齿的患病率,并改善口腔及全身健康。
