An Introduction to Basic Dental Students

GENERAL FEATURES OF DENTAL INSTRUMENTS
Working end(s) of instruments
•Are the functional parts of the instrument
• Can have a variety of functions including: cutting, packing, carving, placing and condensing
•Are adapted to the function of the particular instrument
•May be bevelled (i.e. the working end is cut at an angle)
• An instrument can be single-ended (one working end) or double-ended (two working ends)



Shank of an instrument
• The part between the working end and the handle
• Can be straight or angled
• The function of the instrument determines the angle and flexibility of the shank 
Handle of an instrument
• Is the part of the instrument that the operator grasps
•Provides stability and leverage
• Design is related to the function of the instrument
• Examples:
   The handle of an upper extraction forceps may be curved to facilitate a palm grasp for the operator
 The handle of a rubber dam clamp forceps is rounded to fit in the palm of the operator’s hand
 A serrated handle allows a better grip
 A large handle allows a palm grasp

THE BASIC DENTAL INSTRUMENTS
Mouth mirror and handle


Functions
•To provide indirect vision
•To reflect light
• For retraction and protection of oral tissues
• For magnification (the number of the mirror represents size of mirror head)
Varieties
• Single-sided or double-sided
• Can be disposable
• Plain or magnifying

Sickle/contra-angled probe
Functions
• Detection of:
 defective pits and fissures
 calculus
 deficient margins of restorations, crowns and bridges
 caries
• Examination (pointed tip allows good tactile sensitivity)
Varieties
• Can be single-ended or double-ended
• Many different styles available
•Working ends may vary (straight, curved)

Periodontal probe


Function and features
• Measure the depth of periodontal pockets
•Tip is calibrated in millimetres
•Blunt end reduces the possibility of tissue trauma
Varieties
• Single-ended or double-ended
• Can be straight, curved or at right angles
• Plastic types available

Briault probe


Function and feature
• Detection of caries on mesial and distal surfaces
• The angled working ends facilitate adaptation to interproximal surfaces

College tweezers and Locking college tweezers


      locking

Functions
• Placing small objects in the mouth and retrieving small objects from the mouth
• Locking type ‘lock’ to prevent dropping materials
Varieties
• Locking and non-locking types
•Working ends can be straight, curved, serrated or smooth

Metal ruler


Function
Measurement of length, e.g. endodontic K files
Varieties
• Can be calibrated in different units of measure
• Plastic type available

  3. Dental students on completion of a conventional didactic course and two succeeding cohorts of second year dental students on a recently presented problem-based learning (PBL) course at The University of Liverpool School of Dentistry. A 40 part true/false questionnaire tested recall of actual knowledge in anatomy, biochemistry, oral biology and physiology. The results revealed no factor in the complete ratings when adversely noticeable between the traditional and PBL course categories but higher complete ratings in the PBL groups when positively marked.Dental Instruments
