POLYMER BUR or SMART BUR
The SMARTPREP Instrument is a medical grade polymer that safely and effectively remove decayed dentin, leaving healthy dentin intact.
The hardness of instrument is less than that of healthy dentin and enamel but harder than carious dentin
SELFLIMITING
The polymer instrument is self-limiting and will not cut sound dentin unless applied with great force, and then it will only wear away, rather than cut, the healthy dentin
Smartprep instrument in a range of sizes (equivalent to round burs nos. 2, 4 and 6)
The Smartprep Instrument is used in a slow speed handpiece (500-800 rpm) to complete caries removal
They are single-patient-use rotary instruments
Carious tissue is removed with circular movements starting from the centre to the periphery.
ADVANTAGE
They are being used for deep caries removal in anticipation of an indirect pulp capping procedure
Use the Smart-Prep burs in the beginning of their clinic experience and hopefully a
void iatrogenic pulp exposures
DISADVANTAGE
Polymer bur left large amount of decayed tissue unexcavated (underprepation)
Technique sensitive (the Smart Prep can be readily defeated by the dumb operator)
the burs disintegrate when they touch enamel or even sound dentin
potentially expensive
hello sir,
ReplyDeleteI am a post graduate student from India in department of conservative and endodontics. i have decides to take some conservative topic for my research work. i am a regular visitor to your blog so i decided to take some suggestion from you in this regard that what would be an appropriate subject to work on. like wise i have some in my mind and they are
1. dentinal chip as the alternative means for direct pulp capping.
2. polymer burs (their efficacy and comparison with conventional tc burs )
3. comparative study in between the total etch and self etch.
so, sir i am looking foreword for your response.
you can mail me at sarannikhil@gmail.com.
regards,
Dr.NIkhil saran
