Raquel Rico

LEARNING OUTCOMESAfter completion of this module the

learner will be able to: Describe the purpose of stain removal. Understand the term “selective

polishing.” Recognize the effects polishing may

have on the teeth and present restorations.

Recognize the effects polishing may have on the gingiva.

PURPOSE OF STAIN REMOVAL Esthetics

“Selective Polishing”- indicated only if there is a need for pt tx.

Effects of cleaning and polishing

PURPOSE CONT: Precautions1. Bacteremia potential due to use of

power-driven instruments 2. Manipulation of the gingival tissues

Environmental Factors1. Aerosol Production2. Spatter

EFFECTS ON TEETH Removal of Tooth Structure **polishing for 30 seconds with a pumice paste may

remove as much as 4 um of the outer enamel.

Demineralized Areas Areas of Thin Enamel, Cementum, or

Dentin Care of Restorations and Implants Heat Production (pain and discomfort

for the patient)

EFFECTS ON GINGIVA Trauma to gingival tissues Removal of epithelium Patient Discomfort Pumice = irritation source Foreign body reactions to abrasives

(delayed healing following tissue trauma)

“SELECTIVE” STAIN REMOVAL The decision to polish is based on

consideration for the individual patient.

Patient education and instruction for stain prevention is important .

SUMMARY OF CONTRAINDICATIONS FOR POLISHING

No unsightly stain Characteristics of patients at

risk for (risk for dental caries) Patients with respiratory problems Tooth sensitivity (abrasive agent

may uncover dentinal tubules) Restorations Newly erupted teeth

(mineralization is incomplete) Conditions that require

postponement for later evaluation
