Dr. Michael O'Sullivan
Associate Professor/Consultant (Professo, Dental Science


Michael O'Sullivan qualified in dentistry from Trinity College Dublin in 1990. After a time in general dental practice he completed a MSc in Conservative Dentistry at the Eastman Dental Institute and University of London and fellowships from the Royal College of Surgeons in Ireland and Edinburgh (FFD RCSI and FDS RCS(Ed)). He then undertook specialist training in Restorative Dentistry at the Dublin Dental School and Hospital, completing training in 1998 and his Intercollegiate Specialist Fellowship Examination from the RCSI.

He also completed a PhD in Biochemistry at Trinity College with Professor Keith Tipton entitled "Semicarbazide-sensitive Amine Oxidase in Human and Porcine Dental Pulp" graduating in 2001. From 1999-2001 he completed a Research Fellowship with Dr Mary McDougall and a Clinical Fellowship with Dr Robert Cronin, both at the University of Texas Health Science Centre at San Antonio, Texas.

He returned to Ireland in 2001 and was appointed a Senior Lecturer /Consultant in Restorative Dentistry (Special Dental Needs) in the Division of Restorative Dentistry and Periodontology at the Dublin Dental School and Hospital, Trinity College Dublin. He was the Clinical Director of the DDUH from 2009-2015.

He is currently The Director of Teaching and Learning (Postgraduate) for the School of Dentistry and The Director of Graduate Prosthodontics. He is also the Chairperson of the Irish Committee for Specialist Training in Dentistry and sits on the Education and Training Committee of the Dental Council.

Research Expertise


(1) Special Dental Needs The Restorative Special Needs Clinic is a tertiary referral centre for the treatment of patients with developmental craniofacial and dental anomalies. These are hereditary /developmental disorders that may affect the number, size or quality of teeth. The most common condition is hypodontia, where a person's teeth fail to develop. There is currently no data available for Ireland, but based on other European figures the number of patients in Ireland missing five or more teeth is likely to be 12,000. The general incidence of hypodontia in European population is 2.3-10.1%. The second most common condition is amelogenesis imperfecta. This term covers a range of conditions where all the enamel is defective. It may present merely as marked pitting of the surface of the tooth to severe cases where the enamel disintegrates upon eruption of the tooth. No data is available on its incidence but studies from other populations put its incidence at 1-2% of the total population. Other dental conditions occur less frequently, such as dentinogenesis imperfecta (the layer under the enamel is poorly formed leading to tooth fracture) and conditions that also affect hair, skin and nails such as ectodermal dysplasia. Research interest in this area includes the clinical management of this population, establishment of a National Database of developmental dental disorders and investigation of the Quality of Life issues associated with these disorders (2) Food Science & Nutrition (with Dr Michael Crowe, Division of Restorative Dentistry and Periodontology) This group, with external collaborators, was established in 2014 with one doctoral student in order to promote teaching and research in the area of Food Science & Nutrition. The Undergraduate Dental Science Programme did not provide teaching in the area until 2019 when this group introduced a module into the curriculum. Our research plan will add to the evidence-based knowledge on improving population oral health and healthcare and translate it into teaching to improve the information delivered in everyday practice. Research to date has focussed on: . Data analysis of National cohorts to investigate dental aspects of child health. . Using data science techniques such as predictive modelling and decision tree techniques to illustrate the importance of these determinants. . Investigating the links between dietary intake and both dental and weight problems in children. . Using association analysis to determine the consumption pattern of cariogenic food and drink in 3 year-old children. . Developing algorithms and data mapping techniques to determine the dietary intake of free sugar in preschool children Outputs achieved to date: 1. Four peer reviewed papers in international dental and nutrition journals, 8 oral and 3 poster presentations (2 international and 9 national conferences), PhD completed, 5th paper at submission stage. 2. Novel aspects of research- using data science techniques (classification trees) to highlight the links between dietary intake and oral health of children and advanced mapping techniques to link different national cohort datasets. 3. Promoted the profile of DDUH in the area of food-related research, including "sugar tax", within a number of institutions including the ESRI, The Food and Health Institute UCD, The Nutrition Society of Ireland, The International Association of Dental Research, The Society of Longitudinal and Lifecourse Studies and The Irish Dental Association. 4. Invited to and participated in the stakeholders consultation workshops (2015) regarding the development of an Obesity Policy and Action Plan 2015-2025. 5. Highlighted the importance of adopting the common risk factor approach to deal with overweight/obesity and dental caries. This approach can generate interdisciplinary research interest and policy options for the DDUH to pursue.

    • Investigating the effect of skeletal pattern in determining articulator settings for prosthodontic rehabilitation: An In-vivo study.
  • Summary
    • Abstract Aims. During extensive prosthodontic treatment the use of an accurately adjusted articulator is recommended to simulate some mandibular movements. This clinical study was undertaken to assess any possible effect of underlying skeletal pattern on programming articulator settings. Materials and Methods. Subjects were recruited (N=73) from a dental school and two regional specialist orthodontic units. Subjects were allocated into groups based on underlying sagittal and vertical skeletal patterns by a group consisting of three orthodontists and three prosthodontists who examined profile photographs. Electronic pantographic recordings were made of each subject with the Cadiax® Compact system to record the sagittal condylar inclination (SCI), progressive mandibular lateral translation (PMLT) and immediate mandibular lateral translation (IMLT). Results. Agreement between assessors for sagittal skeletal pattern classification was excellent (97% for total or good agreement). Agreement between individuals for vertical skeletal pattern was high, but at a lower level than for sagittal relationships (70% for total or good agreement). SCI settings for sagittal II subjects were significantly higher than those for sagittal I (p<0.05) and sagittal III (p<0.001) subjects. No statistical difference could be observed between the SCI values of the sagittal I and sagittal III groups. Subjects with an average vertical skeletal pattern had SCI values lower than those with a reduced vertical skeletal pattern (p=0.058) and significantly lower than subjects with an increased (p<0.01) vertical skeletal pattern. No patterns could be determined for PMLT or IMLT between the study groups. The PMLT measurements for all study groups clustered at the minimum value (5°) and to a lesser extent the maximum (15°). The majority of the sample population had IMLT settings of 0mm, with the remaining values ranging from 0.1 mm to 1mm. Conclusion. During prosthodontic treatment of patients with a noticeable skeletal discrepancy consideration should be given to customising SCI values.

    • Disinfection procedures: Their efficacy and effect on dimensional accuracy and surface quality of an irreversible hydrocolloid impression material
  • Summary
    • Abstract Objectives: This study investigated the antibacterial efficacy and effect of 0.55% orthophthalaldehyde (Cidex OPA1) and 0.5% sodium hypochlorite (NaOCl) on the dimensional accuracy and surface quality of gypsum casts retrieved from an irreversible hydrocolloid impression material. Methods: A simulated clinical cast and technique was developed to compare the dimensional accuracy and surface quality changes of the test gypsum casts with controls. Dimensional accuracy measurements were completed between fixed points using a travelling microscope under low angle illumination at a magnification of X3. Surface quality changes of ''smooth'' and ''rough'' areas on the cast were evaluated by means of optical profilometry. The efficacy of the disinfection procedures against Pseudomonas aeruginosa was evaluated by determining the number of colony forming units (cfu) recovered after disinfection of alginate discs inoculated with 1 X 106 cfu for defined intervals. Results: The dimensional accuracy of the gypsum casts was not significantly affected by the disinfection protocols. Neither disinfectant solution nor immersion time had an effect on the surface roughness of the ''smooth'' area on the cast, however, a significant increase in surface roughness was observed with increasing immersion time for the ''rough'' surface. Complete elimination of viable Pseudomonas aeruginosa cells from alginate discs was obtained after 30 and 120 s immersion in Cidex OPA1 and NaOCl, respectively. Conclusions: Immersion of irreversible hydrocolloid impressions in Cidex OPA1 for 30 s was proved to be the most effective disinfection procedure.

    • Maxillary anterior tooth dimensions and proportions in an Irish young adult population
  • Summary
    • SUMMARY This study was undertaken in a young Irish population to determine the dimensions and ratios of the six maxillary anterior teeth. One hundred and nine Irish subjects (age 18-25 inclusive) had irreversible hydrocolloid impressions made of their maxillary dentition poured in type V stone. Clinical crown dimensions were measured with a digital calliper. The stone casts were digitally photographed in a standardised manner enabling calculation of various ratios between the maxillary anterior teeth. Sexual dimorphism existed for various tooth dimensions; most notably canine teeth were in the region of 0.8 mm longer and 0.6 mm wider in males. Central and lateral incisors were found to be 0.5 mm wider in males. It is, therefore, recommended that dimensional tooth guidelines should be given for each of the sexes and not on a population basis. With regard to tooth proportion ratios, no significant differences were found between genders or the left and right sides for any of the measurements or ratios measured. The digitally recorded tooth proportions were similar for both sexes, and the Golden Proportion guidelines could only be applied to the lateral incisor ⁄ central incisor widths (0.618). Identified width proportions for the canine ⁄ central incisor were 0.58 and for canine ⁄ lateral incisor 0.89.
