research about indirect pulp cap
partial caries removal have EQUAL SUCCESS copatred to restored teeth with COMPLETE CAREIS REMOVAL
direct pulp cap success determined by
asymptomatic vs symptomatic
– teeth asymptoamtic and no clinical or radiographic signs of patholgy at time of pulp capping tend to fare better than those teeth with such factors present
indications for INDIRECT PULP CAPPING
on permanent teeth with IMMATURE APICES if all the following conditions exist
- tooth has large carious lesion that is considered likely to resul in pulp exposure during excavation
- NO HISTORY of subjective pretreatment symptoms
- radiographs exclude peri-radicular pathosis
- patient has been fully informed that endodontic treatment may be indicated in the future
indications for direct pulp capping
indicated when all of these conditions exist
- mechanical exposure of a clinically VITAL AND ASYMPTOMATIC PULP occurs
- bleeding is controlled at the exposure site
- exposure permits the capping material to make DIRECT CONTACT with the vital pulp tissue
- exposure occurs when the tooth is under a DENTAL DAM ISOLATION
- adequate seal of the coronal restoration can be maintained
use of cavit? describe
old material
endo and inlay applications
but no occlusal load or compressive sstrength
- LACKS MECHANICAL PROPERTIES – SO NOT ADVISED TO USE IT IN THIN LAYERS OR IN
COMPLEX ENDODONTIC ACCESS CAVITITES
IT EXPANDS TOO MUCH
cavit is made of?
zinc oxide / calcium sulfate material
IRM vs cavit
IRM – zinc oxide eugonal WORSE than cavit - zinc oxide / calcium sulfate
all temporary materials _____ to some extent
LEAK
which is more anti microbial? zinc oxide eugonal (IRM) or cavit
zinc oxide eugonal
describe the resin based temporary materials
must be BONDED to provide an effective seal because they undergo polymerization shrinkage but somewhat offset because
they absorb water and may swell
but lack some of the anti-microbial properties
bonded resins are recommended for temporization?
yes – likely to last more than 2-3 weeks
good choice for long term temporization?
resin modified glass ionomer materials
provide a bond to dentin and enamel and many have antimicrobial properties
composites as material in capping?
etch and primer components are vasodilators and can increase bleeding that contaminates adjacent dentin and degrades adhesin
can also result in INFERIOR PULP healin and can result in INFLAMMATION – poor environment for pulp healing
MPa of resin modified glass ionomer
155 MPa
3X cavit
two examples of good long -term temp materials
GIC
- glass ionmer celments – chemcially bond to hard tooth structure
or resin based materials including composite resin modified glass ionomer cements (RMGIC) – like Fuji
disadvantages to glass ionomer
less polishability than resin
- less esthetic compared to composite
advantages of glass ionomer
clinical studies are there
adheres to dentin and enamel with minimal prep
tooth colored , easy to manipulate
can be used as interim or definitive restorative material
can be used as a base sometimes
good material for caries control?
glass ionomer
the disease control phase as three important components ..
like describe caries control
- caries RISK ASSESSMENT
- evaluation and reevaluation throughout treatment (identify the individual patient risk) - CARIES REMOVAL and placement of TRANSITIONAL RESTORATIONS using FLUORIDE RELEASE restorative materials (glass ionomers)
- chemotherapeutic agents and preventive treatment
pulpotomy’s general associated with
primary teeth – removal of coronal ulp tissue
emergency procedure in permanent teeth until root canal tx can be accomplished and an interim procedure for permanent teeth with IMMATURE root formation to allow continual root development (apexogenesis)
pulpectomy
expiration of normal or diseased pulp to or near the apical foreman
emergency tx for irreversible pulpitits
pulpECTOMY and palce CAOH in the canals and restore the proximal contact wi
th ketac Molar
future endo therapy after the emergency pulpectomy includes
ENDO – core build up with FluoroCore – foundational restoration and place a e.Max all ceramic crown
FluoroCore is what type of material
foundational restoration – core build up often used in endo
