Prior to this study, almost all the research on dental development in chimpanzees came from captive individuals or from a small sample of skeletons collected in the wild and it is unclear how representative these data are of living wild animals.

relatively small canine and incisor teeth similar to Ardipithecus except for a. Since chimpanzees are our closest living relative, it is important to make sure that we document their development before we can fully interpret the fossil evidence. This species was probably similar in size to modern chimpanzees. in height or around a 4-year-old kids height, but weigh almost as much as a 14-year-old boy or between 90 and 120.

Understanding the timing of these developmental milestones in wild chimpanzees is particularly important because evolutionary anthropologists have been debating for years whether early humans followed ape-like or human-like patterns of growth. A common endodontic treatment for severely decayed teeth in a 26-year-old female chimpanzee is reported. The gestation period lasts seven months, a juvenile is sexually mature at eight to ten years and can live up to 60 years old. Azania, one of our female infants, showing that both of her lower first molars (M1s) have erupted before this photo was taken at age 3.1 years. Chimpanzees ( Pan troglodytes ) with teeth severely damaged by dental caries and/or periodontal disease are often managed with medication and/or tooth extraction.
