Introduction to Operative Dentistry Operative Dentistry is the art and science of dentistry which deals with diagnosis, treatment and prognosis of defects of the teeth which do not require full coverage restorations for correction.  To restore Form Function Esthetics INDICTIONS OF OPERATIVE DENTISTRY  Caries  Loss of the Tooth Structure due to Attrition, Abrasion, Abfraction and Erosion (Non carious lesions)  Malformed, Traumatized, or Fractured Teeth  Aesthetic Improvement  Dental caries Host (teeth) Dental caries is a multifactorial infectious microbiologic disease of Micro- organisms Caries Time the teeth that results in localized dissolution and destruction of the calcified tissue Substrate (CHx) Dental caries Sites  Dental caries types: Pit and fissure Smooth surface Root  Dental caries One surface  Dental caries Two surfaces  Dental caries More Attrition Mechanical wear between opposing teeth as a result of functional and para-functional (Bruxism) movements of the mandible (Physiologic process) Abrasion Abnormal tooth surface loss resulting from direct frictional forces between the teeth and external objects.  Erosion Loss of dental hard tissue as a result of a chemical process not involving bacteria. Exogenous source: Lemon sucking, and Battery factors Endogenous source: Gastric fluid regorge ‘Gastro-osephogeal reflux’’  Abfraction An abfraction is an angular notch at the gumline caused by bending forces applied to the tooth Due to: Chronic heavy forces on teeth, (bruxism). Normal forces on teeth which are improperly aligned (malocclusion). Malformed, Traumatized, or Fractured Teeth Malformed, Traumatized, or Fractured Teeth Teeth discoloration Enamel hypoplasia o Is a defect of the teeth in which the enamel is hard but thin and deficient in amount, caused by defective enamel matrix formation. o Usually the condition involves part of the tooth having a pit in it. Enamel hypoplasia Enamel Hypo- calcification Is a defect of tooth enamel in which normal amounts of enamel are produced but are hypomineralized. In this defect the enamel is softer than normal. Aesthetic Improvement Restoration Replacement or Repair  Scope of Operative Dentistry  Diagnosis  Prevention  Interception  Preservation  Restoration  Maintenance  OBJECTIVE OF OPERATIVE DENTISTRY  Restore the tooth into normal function.  Restoration of normal occlusion.  Enhance the general health, oral hygiene and motivate the patient for regular checkup.  Post-operative instruction. THANK YOU
