Abstract

Objectives: Comparison of maxillary, mandibular, dental crown and root mineral density in human skeletons identified in historical excavations with today's human maxillary, mandibular dental crown and root.

Methods: After the skull images were obtained, four groups were created: maxilla 1, mandible 1 from the old period, maxilla 2 from the images taken from today's patients, and mandible 2 from the images taken from today's patients. Seventeen skeletons were previously classified as young age, middle age, and older age. Among the archive tomography images, 17 images from young (15-35), middle (36-56) and older (57 and over) age images were included in the study. HU value of the desired region was calculated automatically by the device using Region of interest (ROI).

Results: In this study, 34 jaws and 68 teeth were evaluated, including 7 mandibles and 10 maxillae from the late Roman period, and 8 mandibles and 9 maxillae from today's people. The average HU value of the crowns of mandibular anterior teeth from the late Roman period was measured as 2406.0. The average HU value of the crowns of maxillary anterior teeth was found to be 3383.8. In the posterior aspect, the average crown HU value measured in the maxilla was found to be higher than that in the mandible.

Conclusions: The finding showed that the density of dental tissues of ancient people, such as enamel and dentin forming the crown, and cementum and dentin forming the root, was significantly higher than today's people.

罗马时期古人类骨骼牙齿结构的矿物质密度与现代人类牙齿结构的比较

目的：将历史发掘出的人类骨骼中的上颌骨、下颌骨、牙冠和牙根矿物质密度与当今人类的上颌骨、下颌骨、牙冠和牙根进行比较：比较历史发掘中发现的人类骨骼中上颌骨、下颌骨、牙冠和牙根的矿物质密度与当今人类上颌骨、下颌骨牙冠和牙根的矿物质密度：在获得头骨图像后，创建了四组：上颌骨 1、旧时期的下颌骨 1、从当今患者图像中提取的上颌骨 2 和从当今患者图像中提取的下颌骨 2。17 具骨骼先前被分为年轻、中年和老年。在这些档案断层扫描图像中，有 17 幅分别来自年轻（15-35 岁）、中年（36-56 岁）和老年（57 岁及以上）的图像被纳入研究。设备通过感兴趣区（ROI）自动计算所需区域的 HU 值：本研究共评估了 34 个颌骨和 68 颗牙齿，包括罗马晚期的 7 个下颌骨和 10 个上颌骨，以及现代人的 8 个下颌骨和 9 个上颌骨。经测量，罗马晚期下颌前牙牙冠的平均 HU 值为 2406.0。上颌前牙牙冠的平均 HU 值为 3383.8。在后部，上颌测得的牙冠平均 HU 值高于下颌：研究结果表明，古人牙齿组织的密度，如构成牙冠的牙釉质和牙本质，以及构成牙根的牙胶和牙本质，明显高于今人。

期刊介绍： The Journal is committed to serving ISCD''s mission - the education of heterogenous physician specialties and technologists who are involved in the clinical assessment of skeletal health. The focus of JCD is bone mass measurement, including epidemiology of bone mass, how drugs and diseases alter bone mass, new techniques and quality assurance in bone mass imaging technologies, and bone mass health/economics. Combining high quality research and review articles with sound, practice-oriented advice, JCD meets the diverse diagnostic and management needs of radiologists, endocrinologists, nephrologists, rheumatologists, gynecologists, family physicians, internists, and technologists whose patients require diagnostic clinical densitometry for therapeutic management.
