A survey on the disposal of blood-contaminated tampon after dental extraction

This paper was to assess the risk for cross infection caused by blood-contaminated tampon after dental extraction and whether this risk was reduced after relevant education towards both dentists and patients.

From December 2014 to April 2015, a survey was conducted in dentists and patients randomly before and after relevant education. The questionnaire is being revised for this survey based on learning from Chatzoudi and Franklin' survey. This survey was approved by the institutional review board, and all participants were voluntary and all responses were anonymous.

Only 2.82 % of dentists provided patients with the postoperative-advices regarding how to dispose of blood-contaminated tampon at the first time and 47.10 % at the second time (P < 0.01). Only 1.41 % of dentists given special postoperative-advices regarding disposal of tampon to patients with blood-transmitted diseases at the first time and 24.64 % at the second time (P < 0.01). Before education, most patients were lack of nosocomial infection knowledge. After education, 22.4 % of patients threw the blood-contaminated tampon away in a proper way (P < 0.01). 66.67 % of them washed hands immediately and thoroughly after they touched the tampon (P < 0.05), 92.71 % knew the blood-contaminated tampon can cause cross-infection (P < 0.01), and 80.21 % knew how to dispose of the blood-contaminated tampon correctly (P < 0.01).

The high risk of cross infection caused by blood-contaminated tampon is evident, and a series of measures is proposed to control it. There is a need to improve both dentists' and patients' awareness, enhance the education of doctors and perfect the policies and guidelines.
