 Steps LA RD/ Isolation Order of restorations Steps of restorations – Caries excavation – Restoring the tooth Types of restorations Interim Permanent  Caries excavation “complete removal” of carious tissue, nonselective removal We use selective caries removal partial incomplete ultraconservative carious tissue removal No caries removal  International Caries Consensus Collaboration (ICCC) “Selective” removal of carious tissue implies different degrees of carious tissue removal in the “peripheral” and “pulpal” areas depending on the dep – sufficient depth to allow a stable restoration to be placed of the lesion – No pulp exposure  Soft Firm Hard – tactile parameter – Subjective Hermetically sealed restoration  Caries excavation Hand instruments Rotary  The low-speed handpiece (500 to 15,000 rpm) is most frequently used for caries removal and for polishing and finishing procedures. light pressure and brushing strokes should be used when using the low-speed handpiece  high-speed handpiece (100,000 to 300,000 rpm, either electric or air turbine) combined with coolant. intermittent cutting at intervals of a few seconds with light, brushing strokes should be done to prevent excessive heat generation  Spoon Excavators Function – To remove carious dentin Secondary functions: – To remove temporary crowns – To remove temporary cement in temporary restoration – To remove permanent crown during try-in Characteristics – Concave design, spoon-shaped with cutting edge Range of sizes: – Large— – Small—Round blade – Single or double ended Practice Notes – Spoon Excavator is used on restorative tray setups.  Bur To be used in a high- or low-speed handpiece Parts: – Head: Part of bur that cuts, polishes, or finishes Available in a variety of shapes and sizes – Neck: Part of bur that tapers to connect shank to head – Shank: Part of bur that is inserted into the handpiece Length and style of shank vary depending on handpiece used. – Bur with straight, long shank fits into straight slow-speed handpiece. – Bur with latch-type shank fits into contra-angle slow-speed handpiece (friction grip bur shown). – Friction grip bur fits into high-speed handpiece; chuck, lever, or push button tightens bur into the handpiece. – Bur with long shank used for surgical procedures Image source:Pre-Clinical Dental Skills at a Glance, First Edition.

Proper application of resin-based composites in posterior teeth requires knowledge of adhesives, composites, polymerization kinetics, and the ability to apply those principles to the patient being treated.
