Study Notes

Dental Polishing

  • Dental polishing is a procedure for removing plaque and stains from teeth.
  • It's a common method for stain removal.
  • Polishing utilizes a handpiece, rubber cup, and abrasive agent.
  • The process involves patient preparation including medical history check, contraindications, draping, appliance removal, and protective eyewear.
  • The patient should be educated on the procedure, and questions answered.
  • The equipment used in conventional polishing includes polishing handpiece, rubber cup, polishing paste, gauze, and floss.
  • Different types of abrasives are available, from extra-coarse to extra-fine.
  • The greater the amount of agent used, the more abrasive the result will be.
  • The lighter the pressure and slower the rotation speed, the less abrasion.
  • The fulcrum must be positioned for wrist and forearm movement, and may be intraoral or extraoral.
  • Stains can be extrinsic (surface) or intrinsic (within the tooth).
  • Extrinsic stains can be removed by polishing.
  • Proper polishing strokes involve starting from the gingival third towards the incisal third, using light pressure and a patting/wiping motion.
  • An important tool is establishing a finger rest and placing the cup almost in contact with the tooth.
  • Dental polishing uses slow speed; the cup must be lightly applied for 1-2 seconds.

Intended Learning Outcomes

  • Students should define the polishing procedure.
  • They should describe the benefits of any polishing modality.
  • Discuss conventional polishing equipment.
  • Demonstrate proper patient preparation strategies.
  • Demonstrate safe clinical practice when polishing.
  • Show proficiency in assessing the polish quality and offering advice to prevent future stains.

GDC Learning Outcomes 2013

  • Describe oral diseases and their relevance to prevention, diagnosis, and treatment.
  • Recognize oral cavity and patient abnormalities, raising concerns where necessary.
  • Understand and manage risks in the clinical environment safely and efficiently.
  • Advise on and apply preventive materials and treatments as appropriate.
  • Undertake non-surgical treatments (under prescription) to remove stains using relevant methods.

Assessment

  • Formative assessment includes quizzes, practical demonstrations, and class discussions.
  • Summative assessment is based on the FCSP handbook.

Recall Dental Stains Lecture

  • Stains adhere to teeth directly, within hard or soft deposits, or within the tooth structure.
  • Stains are classified as extrinsic (surface) or intrinsic (within the tooth).
  • Extrinsic stains are removable by the operator.

Benefits of Polishing

  • Polishing creates a smoother tooth surface for easier cleaning.
  • Patients are more likely to cooperate and maintain oral hygiene themselves once teeth are polished.
  • Polishing slows down the formation of new dental deposits.
  • Fluoride is better absorbed by enamel after polishing.

Main ways of polishing

  • Conventional polishing uses handpieces and abrasive agents.
  • Air-flow polishing utilizes a different, specialized equipment.

Safety in Polishing

  • It's crucial to check the patient's medical history for contraindications before starting the process.
  • Use appropriate protection (e.g., bib, eyewear) for both patient and operator.
