AIM
The aim of the present study is to evaluate the reduction of the distal teeth towards the medial ones in one functional dental group in southern Bulgarian population.
MATERIALS AND METHODS
The study included 232 Bulgarians aged 20-40 years. Mesiodistal dimensions of the teeth were measured by Dentistry Sliding Vernier Caliper and analyzed with SPSS 23.0. Four interdental indices were calculated: inter-incisive, premolar, upper, and lower molar indices.
RESULTS
We found a decrease in the percentage ratio of the lateral to the central incisors of people from the Bulgarian population compared to those dating from the Eneolithic period on the territory of Bulgaria. Furthermore, we found a reduction in the percentage ratio of the upper and lower second molars compared to the first ones. The biggest reduction in the percentage ratio (more than 6%) was found in the lower second premolars compared to the first ones, which is characteristic for southern Bulgarians.
CONCLUSION
There was a dental reduction in all the distal members compared to the medial ones participating in one morphological dental group. As a result, we think that interdental indices can be used for explaining historical, cultural, and biological macro and microevolutionary processes and thus for understanding the origin, formation, contacts, and migration pathways of the different populations leading to ethnic variation of humanity. Therefore, they can be a reliable source of information in physiological anthropology.
目的
本研究旨在评估保加利亚南部人群一个功能性牙组中近中向远中牙齿的减少情况。
材料和方法
本研究纳入了 232 名 20-40 岁的保加利亚人。通过牙科滑动游标卡尺测量牙齿的近远中尺寸，并使用 SPSS 23.0 进行分析。计算了四个牙间指数：切牙间指数、前磨牙间指数、上颌磨牙间指数和下颌磨牙间指数。
结果
与保加利亚新石器时代的人群相比，我们发现保加利亚人群的侧门齿与中门齿的比例有所下降。此外，我们发现上颌和下颌第二磨牙与第一磨牙的比例也有所减少。与第一前磨牙相比，第二前磨牙的比例减少最大（超过 6%），这是南部保加利亚人的特征。
结论
在参与一个形态牙组的所有远中成员中，与近中成员相比，牙齿数量有所减少。因此，我们认为牙间指数可用于解释历史、文化和生物的宏观和微观进化过程，从而有助于理解不同人群的起源、形成、接触和迁徙途径，以及导致人类种族变异的原因。因此，它们可以成为生理人类学中可靠的信息来源。
