disease or injury to hard tissue that restores atooth to the original form(Tylman).  \nThe current focus is on conservative tooth preparation thatis noninvasive and that minimally involves dentin.This trend isrational in the light of the reduction of the caries rate by fluorides,nutritional counseling and oral hygiene programs.Black'sprinciples of cavity preparation and Tylman's principles of toothpreparation are both presently being modified to accommodateimaginative approaches i.e.,acid etching with minimumreduction.Dentistry is changing from macro tooth preparation toan environment of molecular chemistry i.e.,esthetic bonding.These techniques are not presently supported by longitudinalstudies,but are exciting and promising.  \nPC.TS  \noEN  \nDespite these advances,traditional crowns are stillindicated for majority of patients.The classic design of thepreparation must be visualized so that modifications if requiredcan be instituted.Diagnosis and disciplined tooth preparation areessential to successful fixed prosthodontics.  \nPC.T  \n# OBJECTIVES OF TOOTH PREPARATION\n\nThe objectives of preparation remain clearly defined,but themethods of securing these goals are constantly being revised.  \n1.Reduction of the tooth in miniature to provide retention.  \n2.Preservation of healthy tooth structure to secure resistanceform.  \n3.Provision for acceptablefinish line.  \n4.Performing pragmatic axial tooth reduction to encouragefavorable tissue responses from artificial crown contour i.e.,fluting of molars.  \n# PRINCIPLES OF TOOTH PREPARATION(According to Rosenstiel)\n\nPC.T  \n# PRINCIPLES OF TOOTH PREPARATION\n\nAccording to Shillingburg,the design of a preparation for acast restorations and the execution of that design are governedby five principles:  \n1.Preservation of tooth structure  \n2.Retention and resistance  \n3.Structural durability  \n4.Marginal integrity  \n5.Preservation of the periodontium.  \n# BIOLOGIC CONSIDERATIONS\n\nPrevention of damage during tooth preparation:  \nAdjacent tooth:Iatrogenic damage to an adjacent tooth is acommon error during tooth preparation.Even if a damagedproximal contact area is carefully reshaped and polished,it will bemore susceptible to dental caries than the original undamagedtooth surface.This is presumably because undamaged surfaceenamel contains higher fluoride concentrations and the interruptedlayer is more prone to plaque retention.The techniques of toothpreparation must avoid and prevent damage to the adjacent toothsurfaces.","cbCaid30ULulWTpx","https://ap.wps.com/l/cbCaid30ULulWTpx","pdf",1754210,87,"English","# Introduction\n## Objectives of tooth preparation\n## Principles of tooth preparation\n##
