To elucidate compositional changes of the articular disk (AD) of the temporomandibular joint (TMJ) by aging, elements of the ADs resected from 18 cadavers were determined by inductively coupled plasma atomic-emission spectrometry. It was found that calcium contents of ADs in TMJs increased progressively with aging, whereas the sulfur contents of the ADs decreased slightly with aging. Regarding the content of phosphorus, the contents increased progressively with aging. The study revealed that age-related changes of calcium contents in the ADs of TMJs were similar to those in women's pubic symphyses, but not those in intervertebral disks and menisci.
为了阐明颞下颌关节(TMJ)的关节盘(AD)随年龄增长的成分变化,通过电感耦合等离子体原子发射光谱法测定了从18具尸体切除的AD的元素。结果发现,TMJ中AD的钙含量随年龄增长而逐渐增加,而AD的硫含量随年龄增长略有下降。关于磷的含量,其含量随年龄增长而逐渐增加。该研究表明,TMJ的AD中钙含量与年龄相关的变化与女性耻骨联合中的变化相似,但与椎间盘和半月板中的变化不同。
