  • The accuracy of three impression transfer techniques for implant supported prostheses 
    Dullabh, Hemant D.; Sykes, Leanne M. (South African Dental Association, 2008-09)
    Cast framework for osseointegrated implant retained prostheses need to be passively fitting so as not to place undue forces and stress concentrations around the fixtures. Impression materials and techniques play a key role ...
  • Biaxial flexural strength of three ceramic oxide core materials 
    Dullabh, Hemant D.; Herbst, Dirk; Sykes, Leanne M.; Biseswar, Nadir (South African Dental Association, 2017-03)
    INTRODUCTION : Brittleness and low strength render conventional ceramic systems unsuitable for routine restorative use in molars. Modern, high-strength ceramic core materials such as high purity aluminum oxide (Al2O3) ...
  • Comparison of alveolar osteitis with post implant removal osteitis (can a “dry socket” occur after implant removal?) 
    Sykes, Leanne M.; Herbst, Dirk; Dullabh, Hemant D.; Fernandes, N.A. (Nelson Alexander) (South African Dental Association, 2017-07)
    The introduction of dental implants spawned an exponential growth in the number of fixtures being placed to meet the increasing functional and aesthetic demands of patients. In response, manufacturers have flooded the ...
  • A comparison of preload values in gold and titanium dental implant retaining screws 
    Doolabh, Rajesh; Dullabh, Hemant D.; Sykes, Leanne M. (South African Dental Association, 2014-08)
    This in vitro investigation compared the effect of using either gold or titanium retaining screws on preload in the dental implant- abutment complex. Inadequate preload can result in screw loosening, whilst fracture may ...
  • The effects of hydrochloric acid on all-ceramic restorative materials : an in-vitro study 
    Harryparsad, Ashana; Dullabh, Hemant D.; Sykes, Leanne M.; Herbst, Dirk (South African Dental Association, 2014-04)
    OBJECTIVES: The aim of this in-vitro study was to assess the long-term effects of hydrochloric acid on the surface roughness of three all-ceramic restorative materials CEREC VITABLOC® Mark II CAD, IPS Empress CAD® and IPS ...
  • Evaluation of surface characteristics of titanium and cobalt chromium implant abutment materials 
    Herbst, Dirk; Dullabh, Hemant D.; Sykes, Leanne M.; Vorster, C. (South African Dental Association, 2013-09)
    INTRODUCTION: Micro-organism adhesion and plaque formation is affected by surface free energy (SFE), surface roughness, hydrophilicity, surface chemistry, surface charge and the presence of proteins. AIMS: The aim of ...
  • Part 15 : Secondary use of unethically obtained data : fifty shades of grey/ aye/nay 
    Sykes, Leanne M.; Evans, William G.; Gani, Fatima; Vally, Zunaid Ismail; Dullabh, Hemant D. (South African Dental Association, 2017-11)
    On a regular basis, dental practitioners have to make decisions regarding their care of their patients. Previously, dentists did this almost instinctively, drawing upon personal resources such as clinical experience, ...

    A health-care practitioner is an individual who provides preventive, curative, promotional or rehabilitative health care services in a systematic manner to people, families or communities. Sadly, many clinicians could ...
  • Statistical terms Part 2 : Principles of research study design : understanding the options, indications and limitations 
    Sykes, Leanne M.; Gani, Fatima; Dullabh, Hemant D. (South African Dental Association, 2016-08)
    Consider this proposed study. AIM: This cohort case study will use a causal, cross sectional design, based on historical records, to explore and describe the long-term, sequential effects of eating. HO: This study will ...
  • Students’ vulnerability in educational research 
    Sykes, Leanne M.; Dullabh, Hemant D. (South African Dental Association, 2012-06)
    Dental teaching institutions in South Africa recently implemented “learner-centred” curricula and expected educators to alter their teaching styles accordingly, but perhaps without providing adequate training in this ...
  • Treatment versus research : Part 5 : Bridging the boundaries 
    Sykes, Leanne M.; Dullabh, Hemant D.; Brandt, Paul Dieter; Evans, Paul (South African Dental Association, 2016-11)
    For clinicians wishing to embark on research, the obvious choice may be to use their large patient pool, already at their disposal. Gathering information from old files and records is relatively easy and harmless, as ...
