About the Project

The oscillation of the current range of endosonics instrumentation will be measured. Work would then progress to evaluate how cavitation and streaming enhances the activity of the irrigating solution. There is renewed interest in this form of endodontic instrumentation and how it may provide success in root canal treatment

There is an active research group looking at the use of ultrasound in dentistry. We have specialist technical knowledge using scanning laser vibrometry to assess the oscillation characteristics of vibrating objects. However, our work has also investigated the vibrations of endosonic files, retrograde tips and powered toothbrushes.

Funding Notes

We have a thriving international Researcher community and encourage applications from students of any nationality able to fund their own studies (Government scholarship), or who wish to apply for their own funding (e.g. Commonwealth Scholarships, Islamic Development Bank International PhD Scholarships, China Scholarship Council).

At present, we could only consider applications from prospective students with:
- a good biomedical degree, with interests in any of the areas outlined above,
- good command of the English language as outlined in the postgraduate prospectus, prospectus,
- a source of funding to cover tuition fees and bench fees.
