Abstract

Human teeth are unique since one population’s dental pattern might differ from another. Such specific dental characteristics, such as the incisor, are observable in each dentition. Objective: his study analyzed the population differences in Javanese and Chinese-Indonesian populations through observations of the incisal traits, namely winging, shoveling, and double shoveling. Methods: 50 dental casts (76 Javanese samples and 74 Chinese- Indonesian samples) were obtained from Dr. Myrtati Dyah Artaria’s private collection, stored in the Faculty of Medicine, Universitas Airlangga. The traits were observed and scored using the Arizona State University Dental Anthropology System (ASUDAS) and analyzed statistically using crosstab and chi-square methods. Results: Only three out of 13 test results exhibit significant differences (p < 0.05). Conclusion: The dentitions observed in the Chinese-Indonesian samples mirror the immense Chinese acculturation into Javanese cultures through interbreeding that happened generations ago. The gene flow between these two populations appears phenotypically in the dentitions, leading the Chinese-Indonesian samples in this study to express Sundadont traits despite their noticeable facial traits and heritage.

Abstract

 The pattern of facial aging helps put the perception of age into face approximation from the skull, making the facemore recognizable to the next of kin. The objective of this study is to determine the facial aging pattern of Javanesepeople in Indonesia. This study utilized the descriptive quantitative method to identify the highest frequency of thefacial aging pattern variables according to its prominence (0 = Not visible; 1 = Slightly visible; and 2 = Clearlyvisible). This study involved 50 male and 50 female samples of the Javanese population. Each sexed samples weredivided into two age-based groups: 40-44 and 45-49. The wrinkles on males and females aged 40-44 are mostlyslightly or not visible. In the 45-49 age group, the wrinkles are visible on the forehead, eyes, and cheeks. Sexdifferences are found in the forehead and cheek grooves, with males having deeper wrinkles. Premature aging of themale samples might be caused by longer working hours and heavier smoking habits. Aside from sex and gender,ancestry also contributes to a unique aging pattern of the Javanese, differentiating them from other populations. Thecomplex interaction between both sociocultural and biological factors is significant in forming a certain pattern offacial skin aging in different populations and sexes. Aside from its theoretical contribution to studies on humanbiological variations, this study can be referenced to depict more accurate and appropriate facial features in forensiccases that require facial approximations, especially those involving the Javanese people and the general Indonesianpopulation.

Abstract

Background: Human behavior can significantly alter dental conditions. One such behavior is the habit of chewing betel nuts. Known as nginang, this tradition holds social significance in many cultures across Indonesia. Societal beliefs include the idea that chewing betel nuts offers a sensation similar to smoking cigarettes, provides a pastime, reduces bad breath, and even enhances dental health. However, evidence shows that it can cause severe damage to teeth. Purpose: This research aims to analyze the literature regarding the impact of chewing betel nuts on dental conditions and to recommend actions to address the problems caused by it. Reviews: While this habit can have positive aspects, it may also cause tooth damage when practiced with a certain frequency and intensity and using specific compositions. Issues such as calculus, periodontitis, attrition, and antemortem tooth loss may occur due to this habit. However, inconsistencies have been found concerning this habit's relation to caries. Conclusion: A pathological chain reaction triggered by betel nut chewing confirms its detrimental effect on dental health. Further investigations are required to explain the inconsistencies found in this review. The researchers recommend promoting tooth brushing to enable society to maintain its tradition without risking further teeth damage.
