Introduction/Objectives

Common marmoset (Callithrix jacchus) is small new world monkey which is a part of primate families. They have been kept by people as pets for several years. However, they are social wild animals that should never be kept alone because they need the option to mate. They could display a variety of aggressive behaviors such as territorial guarding aggression and sexual aggression. In the estrous period, they could bite even the people they trust. Castration is the option to decrease unwanted behavior which results from hormonal changes as well as restoration and canine teeth cutting could be done also.

Methods

A 3-year-old intact male, common marmoset was presented to the hospital by the problem of sexual aggression. At first castration was performed, but it was not effective in last 3 months. Restoration with composite resin after cutting canine teeth should be a proper option in this case.

Results

The aggressive behaviors were gradually decreased. Although he still attacked, the severity of the wound was not significant. The restorative materials completely retained until last follow up and the color was similar to the enamel surface.

Conclusions

Common marmosets are very social wildlife, so the captivity should provide an environment as similar as the natural habitat to prevent behavioral problems. In addition, castration and dental surgery is just a choice for treatment in this case. Environmental management is recommended.
