1. Propylene glycol is preferred to be used than distilled water as a vehicle for calcium hydroxide paste used as intracanal medication. (This thesis)
2. Sodium hypochlorite is more effective against Enterococcus faecalis inside dentine tubules than Chlorhexidine, Silver Nanoparticles and RISA. (This thesis)
3. Biofilm can remain and regrow inside dentine tubules after irrigation, even without any extra source of nutrition. (This thesis)
4. Higher flow rates are related with higher irrigant velocities inside the root canal models, which are related with biofilm removal. (This thesis)
5. The mechanical effect of irrigation exerted by an extra final flow and ultrasonic activation, even with a non-chemical active solution, has a significant effect on biofilm removal. (This thesis)
6. Sodium hypochlorite and a higher flow rate can influence biofilm removal from the isthmus-like structures, whereas for the lateral canal the flow rate has no influence. (This thesis) 7. The number of irrigant refreshments have no influence on biofilm removal, whereas in the
same biofilm the sequential refreshments presents a cumulative effect. (This thesis) 8. Vulnerability is the birthplace of innovation, creativity and change. (Brené Brown). 9. Time is the true great alchemist, the one who really transforms everything. (Gilberto Gil). 10. The only trust required is to know that when there is one ending there will be another
beginning. (Clarissa Pinkola Estés)
