    • Conservative approach
      Prepared by Dr. ManalFarouk
      Umm Al Qura University
      Faculty of Dentistry
    • operative dentistry is the art and science that deals with diagnosis, treatment, and prognosis of defects of teeth that don't require full coverage restorations for correction
    • conservative treatment starts first with the removal of decay and then replacement the missed part with a suitable restorative material
    • caries removal is done through either hand instruments that remove the soft caries or rotary instruments that remove the hard caries
    • after caries removal the cavity is prepared according to certain criteria or specifications that classify the cavity into 6 classes
    • class 1 that includes only the occlusal surface of posterior tooth
    • class 2 includs the proximal surface of posterior teeth
    • class 3 includes the proximal surface of anterior teeth
    • class 4 includes the proximal surface of anterior teeth including incisal angel
    • class 5 includes the gingival third of the tooth
    • class 6 includes the cusp tip of posterior teeth
    • then cements materials are applied to prevent thermal effects, chemical irritations, and electrical stimulations
    • then cements materials are applied to prevent thermal effects, chemical irritations, electrical
    • the selected final restorative material are then applied
    • Endodontic therapy
    • Pulp is the most inner structure of the tooth it is composed of soft tissue consisting of nerves, blood vessels, and cells. It has many functions
    • pulp functions : the pulp performs 5 main functions some formative, and others supportive
      Induction
      Pulp participates in the initiation and development of enamel
       
      Formation
      Odontoblasts form dentin these highly specialized cells participate in dentine formation
       
    • Nutrition
      Pulp supplies nutrients that are essential for dentin formation
       
      Defense:
      Odontoblasts form dentin in response to injury, particularly when the original dentin thickness has been reduced due to caries, attrition, trauma, or restorative procedures
    • Sensation:
      Pulp transmits neural sensation mediated through enamel or dentin to the higher nerve centers. These stimuli are usually expressed clinically as pain
       
    • Indications
      Pulp exposure
      Periapical lesion
      Pulp death ( trauma)
      Intentional endodontic treatment
    • Diagnosis
      Thermal pulp tester: a) cold b) hot
      Electrical pulp tester
      Percussion test
      Radiography
    • Procedures
      Access preparation: differs with the difference of tooth anatomy
      Cleaning and shaping: mechanical or chemical
      Obturation: guttapercha or silver cones
      Follow up: during the first two years
