Helen Liversidge qualified in dentistry from Stellenbosch, South Africa. She worked in NHS and private general dental practice whilst at the same time completing an MSc (Mineralised Tissue Biology) and PhD (Human Tooth development in an archaeological population of known age) at University College London studying with Professors Alan Boyde and Christopher Dean (respectively). She joined Child Oral Health in the Dental Institute, Barts and The London, Queen Mary’s School of Medicine and Dentistry in 1985. Helen teaches undergraduate and postgraduate dental students in clinical paediatric dentistry and has supervised fifteen postgraduate research projects including four PhD’s (students from England, Ireland, Greece, Libya, Italy, Thailand, Sudan, Saudi Arabia and United Arab Emirates). All these have presented at national/international meetings and published their results. She organises the London Oral Biology Group which meet several times a year for research meeting and attracts scientists with interests in dental anatomy, physiology, zoology and palaeontology.

Research

Research Interests:

Research areas include quantifying the developing dentition, radiographic assessment of developing teeth, accuracy of age assessment using developing teeth and global population differences in tooth formation. Regular international and national presentations at research meetings in the fields of Dental Research, Dental Morphology, Paediatric Dentistry, Physical Anthropology, Forensic Odontology and Human Biology.

Recent research include the London Atlas of tooth development and eruption, in 14 languages, image and software with PhD student Dr Sakher AlQahtani and Prof Mark Hector (Dean , Dundee Dental School). This has become the accepted method to estimate age from the developing dentition. This project was prompted by a question from a forensic odontologist after the tsunami December 2004. Other recent work compared the accuracy of published age estimation methods using developing teeth including the third molar. Another large longterm research project is documenting tooth formation in worldwide population groups. This is a collaborating with paediatric dentists, anatomists, anthropologists, archaelogist colleagues around the world using dental radiographs.  Data have been collected from London UK (Bangladeshi and White), Australian Aborigine, Maori and Pacific Islanders in New Zealand, Japanese,  three groups from Malaysia, South African Blacks and Cape Coloureds, Nigerians, Inuits in Canada and Hispanics and Native Americans in New Mexico.  Other collaborations include West and East Africa.  Research projects with clinical application include predicting third molar and second premolar agenesis from adjacent developing teeth.
