To facilitate the transformation of a patientbased study to a case presentation that can bepresented at Clinic and Research Day
Parameters
How were treatment plans or outcomes for yourpatient affected by: Treatment procedure Patient health concerns Therapeutic problems concerning patient Unusual medications Treatment consideration for medically
compromised or patients with disabilitiesExample: Blood pressure medication that
causes xerostomiaWhatare causes, how do you evaluate, how do you treat?
Where do I find cases?
1.Portfolio

Direct Pulp Capping: Mineral Trioxide Aggregate (MTA) orCalcium Hydroxide (Dycal)?
Student: Andrea VenizelosAdvisors:Satish Alapati, BDS,MS,PhD; BradfordJohnson, DDS, MHPE, UIC Department of Endodontics
CRITICAL QUESTIONDuring caries excavation on a mature adult tooth a pinpoint pulp exposure (<1mm) is noticed, forincreased survival of the tooth, which material should be used for pulp capping: MTA (MineralTrioxide Aggregate) or Calcium Hydroxide (Dycal)?
CAT 1Olsson et al. “Formation of a Hard TissueBarrier After Pulp Capping in Humans. ASystematic Review.” International EndodonticJournal 36pp429-442.2006.Methods: A PubMed and Central literaturesearch with specific terms were made. Level ofevidenceof the publications was assessed.Results/Conclusion: 21 publications remainedafter interpretation. None had a high level ofevidence, one had moderate level of evidence,and 20 had a low level of evidence. Evidencegrade was determined to be insufficient. Doesnot imply that there is no effect of a pulpcapping procedure, but rather a need for high-quality studies. Capping material includedcalcium hydroxide, bonding materials,Vitrebond, synthetic hydroxyapatite, isobutylcyanoacrylate, andMTA.Validity: Had valid inclusion criteria, andevaluated LOE.LOE: 1(Systematic Review)
CAT 2Aeinehchi et al. “Mineral Trioxide Aggregate(MTA) and Calcium Hydroxide as Pulp-CappingAgents in Human Teeth: A Preliminary Report.”International Endodontic Journal 36 pp 225-231.2003.Methods: 22 maxillary third molars weresubjected to mechanical pulp exposure. Pulpcapping material was either MTA or calciumhydroxide, covered with ZOE and restored withamalgam. Extractions were after periods of 1week, 2 months,and 6 months.Results/Conclusion: Less inflammation,hyperemia and necrosis plus thicker dentinalbridge and more common odontoblast layerformation with MTA was found than withcalcium hydroxide.Validity: Direct pulp capping material wasrandomly assigned. Small sample size, largedrop-outof patients.LOE: 2(RandomizedControlledTrial)
CAT 3Nair et al. “Histological, Ultrastructural andQuantitative Investigations on the Response ofHealthy Human Pulps to experimental Cappingwith Mineral Trioxide Aggregate: ARandomized Controlled Trial.” InternationalEndodonticJournal 42pp422-444.2009.Methods: A pulpal exposure was made in 35healthy maxillary third molars from 23patients. Pulp capping material was either MTAor Dycal. 33 of these teeth were histo-morphologically processed. Cavities wererestored with IRM. Extractions were afterperiodsof 1 week, 1 month,and 3 months.Results/Conclusion: Pulp exposures treatedwith MTA were essentially free frominflammation and covered with hard tissuebridges. Teeth treated with Dycal had less hardtissue formation, more pulpal inflammation,and seepageof material into thepulp.Validity: Direct pulp capping material wasrandomlyassigned.Follow upwas 100%
LOE: 2(RandomizedControlledTrial)
CASE SIGNIFICANCEStudent SummaryFew in vivo studies are available on this topic.However, from the available evidence the
following conclusionscan bedrawn:
1. Calcium hydroxide does not adhere to thedentin and lacks the ability to seal. Seepage ofmaterial into the pulp is probable. Hard tissuebridges that form are incomplete and presentwith tunnel defects that act as a pathway formicroleakage.
2. Pulp defects treated with MTA have lessinflammation, less hyperemia, more stable hardtissue bridges with increased thickness, and arefree from tunnel defects. MTA shows greaterability to providea fluid-tight seal.
3. MTA has a much greater cost than calciumhydroxide.
4. There is a need for more high-quality studiesfor MTA to definitively be the material of choicefor direct pulpcapping.

Methods:Part 1 – Retrospectiveevaluationof130patientsw/ 185STIrestorations w/ ZrO2abutments.Part 2 – Clinical examof 25 patientsw/ 40restorationsplaced >3 yrs ago.93cementedw/ zinc phosphate,1 w/ resin cement,1 w/ TempBond
Results/Conclusion: ZrO2abutmentshad lowrate of technical andbiological complications,soft tissue respondedwell.
Validity/Applicability: Multiple focusparametersw/ short follow up butvast datacollection. Protocolfor surgeryandrestorationstandardizedand positive3-5year success.
Levelof Evidence:Low Level 3 – Retrospecitveanalysis and clinical follow upstudy
Many studies have been conducted on ZrO2plates/discs and the vast majority of searchresults were in vitro studies. Systematic reviewswere not available as the material in question isstill fairly newin thescopeof dental practice.
The topic has helped me realize the importanceof material science and its place in dentistry.Bonding concepts, biocompatibility, andphysical/chemical properties are factors thatcontribute a great deal to success within theoral cavity.
Based on my research resin based luting agentsare the best candidates for cementation onto aZrO2substrate such as an implant abutment. Airabrasion, priming, and trebochemicaltreatments are all areas for future research todetermine the best alternative to increase bondstrengths in the zirconia material withoutcompromisingits physical/chemical integrity.
