This research discusses human diet 2000 years ago at the archaeological site of Leang Codong, Soppeng Regency. The research focusses on the analysis 25 of the 27 of loose teeth human teeth found during excavations in 2017. Methods included the recording of tooth wear, and measurements using ImageJ software area for attrition and caries. The research showed that there were traces of attrition on all the teeth with wear scores from 2 to 8. Some caries were also recorded. Following CBCT-scans of the teeth by the dentist faculty at the Hasanuddin University, Makassar, and based on the correlation relationship, there are observed differences in the attrition and caries related to variations in eating patterns based on gender. The level of caries that is not directly proportional to attrition in humans illustrates that the consumption of carbohydrates and glucose was influential in the diet. Meanwhile, in male individuals, the correlation analysis did not show any significance between caries data and tooth attrition. Levels of dental attrition in the teeth from Leang Codong does not show any preference that would indicate a specific centre of gravity ora significant effect on the side of the tooth used in mastication. Based on observations of differences in diet on tooth attrition it can be surmised based on the recorded wear scores and degree of slope remaining on the loose teeth, the inhabitants of Leang Codong belonged to a Palaeometallic farming culture.
