Orthodontics at postgraduate and undergraduate levels


Dr Firth's research activities interests lie in the biology of tooth movement and craniofacial biology. She has a particular interest in the use of tissue culture models to investigate orthodontic movement.

Dr Firth was heavily involved with the development of a mechanical strain model for the assessment of periodontal ligament cell endoplasmic reticulum stress in three-dimensional culture. Her ongoing research is continuing to develop and expand tissue culture models for orthodontic tooth movement research.

Dr Firth is interested in a wide variety of other research areas, including clinical research, craniofacial growth and development and clinical genetics.
