  Five different commercial toothpaste formulations were labeled as A, B, C, D and E and evaluated for toxicity in vitro using reconstituted human oral and gingival mucosa cultures. Toothpastes A, D and E contained sodium lauryl sulphate (SLS) while toothpastes B and C did not. All toothpastes contained fluoride in different quantities. Tissue viability (MTT), tissue morphology (LM and TEM) and release of pro-inflammatory mediator IL-1α were evaluated. For gingival mucosa, topical exposure of toothpastes did not affect MTT values. Examination of oral mucosa however, showed that toothpastes B, E and D induced a significant loss of viability after 1 h (49.2%, 55.5% and 78.4% respectively) (p<0.05). After 3 hours toothpaste B demonstrated a 51.4% loss of viability whereas tissue viability for toothpastes D and E dropped to 11.1% and 4.5% respectiv.. View More»
