- Abstract: Introduction: As the important part of tooth, enamel must be treated well in order to keep its function. The purpose of study is provide tooth composition for various condition and at different ages. Methods: Children (1-2 years), adults (13-40 years), and parents (41-70 years) tooth, aquabidest, abrasive paper, tooth bor, caliper, trimmer, Machines for Hardness test, compressive test and XRD. Each test sample will be cut, mashed, washed and soaked in aquabidest in refrigerator and then to be examined. Results: Micro test results were showed that the main components of the teeth are Hydroxy apatite, Fluorine apatite, and Calcium phosphate hydrate. Transition glass occurs in the age range 1-12 years old at 340o C and in the age range 13-40 years old at a temperature of 400o C , however at the age of 41-70 years old at temperatures of 360o C based on the thermal test results, melting point and boiling point. Mechanical test was showed the level of violence has increased from the age of 1-40 years old then later has decreased, as well as for compressive strength. Hydroxy apatite, Fluorine apatite increase, and Calcium phosphate hydrate decreases in line with age. Tooth enamel also tends to be able to withstand heat in line with age. Conclusion: The level of hardness and tooth strength tends to increase temporarily in older people’s teeth as the calcium content decreases, thus its mechanical strength decreases.
