Research Interests

The longevity of resin composite (RC) tooth restorative materials requires, among other factors, the attainment of optimum mechanical properties on curing. Such properties are dependent on adequate polymerisation which ensures that the residual monomer content in the restoration is minimised. Inadequate polymerisation has been associated with loss of biocompatibility, colour shifts, loss of retention or breakage and excessive wear and softness.  Monomer conversion in light activated materials is governed by exposure to light of adequate intensity and of suitable spectral distribution. Over the last 5 years, the principal aims & objectives in research have been to quantify the effects of different visible light exposure (curing) techniques on the likely durability of commercial dental resin composite (RC) tooth restorative materials. The main parameters investigated have included:•exposure intensity (irradiance)
•exposure time
•exposure wavelength specificity (ie using various light curing units LCUs)
•elapsed time after exposure
•exposure protocol
•exposure distance
•exposure depth
 The following general trends are evident from the work undertaken (within the parameters investigated), relating to VHN (and, by implication, the durability of RC materials as tooth restoratives):(a) lamp irradiance of commercial dental LCUs is not an issue relating to the top surface (adjacent surface) VHN, given sufficient exposure time & elapsed time (b)  lamp irradiance of commercial dental LCUs is an issue with respect to depth of cure (bottom/top VHN ratio) for a given exposure time (c) exposure time is an issue with LCUs up to a limiting exposure time(d) short exposure times are not appropriate (< 10 s) irrespective of lamp irradiance(e) elapsed times of 1-hour and 24-hours yield significantly different VHN(f) soft-start exposure techniques may result in reduced VHN(g) increased LCU distance yields a progressive and significant decrease in VHN I believe that these observations are of considerable importance to the dentist in the handling and placement of visible light-activated resin composite (& related) tooth restorative materials.

Teaching Interests

Dental Materials Science is addressed within the following undergraduate modules (Programme BDS, CK702):
BDS #1: DS1002 Fundamentals of Dental Practice
BDS #2: RD2007 Introduction to Clinical Dentistry
BDS #3: RD3005 Introduction to Dental Practice
BDS #4: RD4001 Theoretical Adult Oral Health
and within the postgraduate (DClinDent) module:
DClinDent #2: OH8000 Clinical Orthodontic Subjects.
At the end of the undergraduate programme in dentistry (BDS), the dental graduate should be able to (in order of importance):
1.identify the scientific basis of generic materials and related procedures
2.select materials appropriate to function and therapy
3.correctly manipulate and apply generic materials
4.appreciate health & safety factors impacting on the use of materials
