RESEARCH PROJECTS UNDERTAKEN

RESEARCH SCIENTIST

Japanese Society for Promotion of Science (Aug 1995-Feb 1997)

The effect of fluoride, sodium, potassium and chlorhexidine on proton excretion (proton-ATPase) and intracellular pH in glycolysing oral bacterial cells grown as continuous cultures under strictly anaerobic conditions was examined.  Proton excretion was measured using a pH stat and meter; pHi by BCECF dye method and fluorescent spectrophotometer; carboxylic acids by the CA ionalyser; glycolytic intermediates by spectrophotometric methods; intracellular polysaccharides by iodine assay; ATPase activity was measured in permeabilised cells; inorganic phosphate and glucose measurements were also made.

RESEARCH SCIENTIST

Health Research Council of New Zealand (May 1994 to July 1995)

The effect of fluoride, phosphate and magnesium ions on the kinetics of the enzyme enolase extracted from caries causing oral bacterial cells was investigated.  Bacterial cells were sonicated and the crude cell extract purified by passing it through an Anion-exchange column followed by a Gel Filtration column. Chromatofocussing techniques were also tried. The purity of the enzyme preparation was checked by SDS-PAGE. The effect of fluoride and phosphate on the kinetics of the purified enzyme was studied. Enzyme activity, and kinetic constants Km, Vmax, and Ki were measured. Nuclear Magnetic Resonance (NMR) techniques were also used to determine the effects of fluoride on enolase by measuring intracellular levels of glycolytic intermediates in fermenting bacterial cells in vivo.

RESEARCH FELLOW/VISITING SCHOLAR

University of Iowa, USA (Nov 1993 - April 1994)

Consultant for an ongoing 3 year longitudinal study designed to determine and measure fluoride intake in 2000 infants and children from all sources in the state of Iowa.  Longitudinal information on daily dietary intake and exposure to fluoride from water, milk, infant formulas and beverages was collected.  This large study provided a number of challenges in terms of the ongoing collection, entry and management of the data by computer programs.  Advise was provided in refining the questionnaire, statistical handling of the data and presentation and writing of reports.

RESEARCH SCIENTIST

Health Research Council of New Zealand and

Tohoku University School of Dentistry, Sendai, Japan  (Nov 1992 - Oct 1993)

The effect of fluorhydroxyapatite-derived fluoride on streptococcal acid production was investigated.  Calcium-phosphate minerals with different concentrations of fluoride were synthesised and chemically analysed for Ca by atomic absorption spectrophotometry (AAS), for phosphate by absorption spectrophotometry, and for fluoride by the ion-specific electrode. The apatites were also characterised by X-ray diffraction, TEM, and by Infra-red spectroscopy. The stoichiometry of release of F, Ca and P ions from the different apatites during progressive dissolution in vitro by three different acid mixtures was studied. In addition, the effect of aerobic and strictly anaerobic conditions on the spectrum of organic acids produced by oral streptococci during the fermentation of glucose was examined.  This part of the study was conducted in Japan.  The ability of the acids produced, under the two conditions, to dissolve the various fluoride-containing apatites was examined. Experience was gained in microbiological techniques, anaerobic methods, the measurement of carboxylic acids by HPLC methods, the measurement of intracellular glycolytic intermediates and pH, and some techniques of enzyme assay.

Ph.D. Degree (1989 to 1992)

An investigation on the factors affecting caries activity in children was conducted as a longitudinal study.  A total of 160 children were examined for caries clinically and radiographically for a period of 12 months.  A sensitive method of monitoring caries activity was developed and computerised.  Information on 99 variables including dietary factors, nutritional factors, levels of fluoride intake from diet, toothpaste, and tablets, salivary factors. socio-economic factors, oral hygiene, general health and medications and demographic factors were collected simultaneously during the study period. Statistical methods including bivariate tests and multivariate logistic regression analysis were used to determine which factors affected the development and progression of caries and caries risk models were developed.

Experience was gained in collecting 24 hour duplicate diets and parotid and mixed saliva; analysis of fluoride in diet, saliva and toothpastes; analysis of diet records for essential nutrients such as Ca, P, Mg, Carbohydrate, Protein, Fat, Vitamins etc using computer programs; taking standardised posterior bite-wing radiographs using individual bite-blocks; recording clinical and radiographic examination data and transferring data to computers; designing and administering questionnaires and the statistical analysis of data.  Developing an Image Analysis system to monitor caries activity was also a major part of the study.

M.D.S. Degree (1987 to 1988)

The Masters degree was undertaken by clinical course work and research on “Levels of Fluoride Intake of Infants in New Zealand”.  The design of the study involved the analysis of 24-hour duplicate diets for fluoride, calculation of amount of fluoride ingested from diet and estimation of fluoride intake from breast-milk, fluoride-tablets, and toothpaste. This study provided information for the first time on the background levels of fluoride intake of infants in NZ. The program also provided a general basis for a scientific approach to research, evaluation of literature, designing research protocols, data collection and the statistical evaluation of results.
