Ciupa, J. 2023. The hard-hitting tooth—Does a scheduled teeth check reduce the number of mice found dead with malocclusion? Animal Technology and Welfare 22(3), 240–241.

Malocclusion is evident around the first 2-5 weeks of age for mice (NC3Rs, 2021). Therefore, it is hypothesised that a regular welfare check, the POST WEAN CHECK (PWC) at 5 weeks would: - significantly increase the health concerns (HC) found as more mice would be diagnosed and caught before being found dead. - Therefore a significant decrease in mice found dead with malocclusion is expected after the PWCs implementation.
