1. INTRODUCTION OF DENTAL INSTRUMENTS USED IN AMALGAM FILLING

2. Dental Mirror:- • Used for indirect vision. • To hold retract your tongue, lips or cheeks. • Tendor to perkashan (TTP). • From the back portion of the mirror we check tht tooth is realy fractured or not. • We wil strike the back portion of the mirror to the patient’s tooth if patient wil blink his/her eye it means tht it is painful and it is fractured.

3. Tweezer:- •To hold cotton roll. • To hold different material. • To transfer any material in and out of cavity. Probe:- (Explorer) • It is sickle shaped. • Used to detect the tooth decay. • To check bifurcation & furcation. Furcation mean branches. • To check the carious region. If we apply probe on tooth and if it move smoothly on surface so it means there is no carious region, there is only stain so we wil not cavity prep and filling.

4. Mortar & Pistile:- Mortar is thick like a bowl and pistele is thin like a pencil. • Used to mix the alloy powder and mercury to make a homogenous mixture. Amalgam Gun:- (carier) Gun shaped. • Used to carry amalgam and dispense the amalgam in cavity. OR

5. Cement Spatula:- • Used for mixing. Tofflemire matrix band retainer:- • Used to hold the matrix band. • To maintain stability of matrix • band during condensation of • restorations Parts Of Tofflemire Matrix Band Retainer:-  Adjusting Nut  Locking Nut used for tight.  Retaining screw  Two slots  Head (u-shaped)  Vise (box shaped) Locking Nut Adjusting Nut Slots Head Vise Retaining Screw

6. Matrix Band:- It has a concave surface (upward) & one convex (downward). The conxity of matrix band should put up on the occlusal surface. • Used to support the wall of class II. • To replace missing proximal walls of • cavity preparation for condensation • of restorative material Wooden Wedge:- Pointed sharp part should be apply b/w the teeth. • Used to tight the matrix band. • Used to comress the gingiva. • used to separate the very tight band. • To hold matrix band in place • along gingival margin of class II. Wooden wedge absorb saliva then they expand and fill the space b/w tooth, and it has low strength as compared to plastic wedge. Matrix bands

7. Condenser:- • Used to condense the amalgam. • Used for packing the amalgam into cavity. Burnisher:- One end of burnisher is egg type shaped & other end is T-shaped. • Used for burnishing.

8. Excavator:- Spoon shaped. • To remove temporary fillings. • To remove soft caries or dentine. • Scoope out/excavate soft dentine. Dycal Applicator:- Small ball shaped at the tip of it. • Used for application of lining. Carver:- 1-Fraham’s Carver: kite shaped.

9. 2-Ward’s Carver:- Pointed, sharp edges. • Both carver is used to remove the excessive material. • To produce the normal tooth anatomy. Plastic Instrument:- Hockey shaped. • Used for application of composites. • To carry composite material for • cavity preparation, and shape • composite,

10. Micro Brush:- Small plastic instrument with small fiber bristled head. • Use to apply primer, dentine bond, enamel bond, sealants. Mylar strips:- Straight strips same as matrix band. • Thin clear strip used to isolate cavity prep. • Able to use cure light b/c it is plastic strip.

11. Curing Light:- Material must be cured in increments of 2 mm or less, need to be above 300 wavelength. • To harden light-cure materials, bonding, composites, sealants, cements, build up. Bonding Agents:- Differs in generation, all in one unit, 3 step, 2 step, brands require different techniques • Acts as an adhesive between the tooth and the composite material.

12. Etch:- White syringe in which blue gel type material is filled. • To remove smear layer and prepare tooth for bonding. Dycal (Calcium Hydroxide Composition):- A base and catalyst paste, mixes together to form a tan paste, self sets. 1:1 ratio mix . • Used for indirect pulp cap, protective liner for deep cavities .

13. Packable Composite:- Different grits: coarse to extra- fine; various sizes; snap-on (with metal center) or screw-on To contour (coarse grit) or polish and smooth
