Article Snippet: , Experimental in vitro study. , Stereolithography (SLA). Stereolithographic printer (Formlabs Form 1). Photocurable composite resin (UDMA/GDMA). , Layer thickness: 300 μm in XY plane and 25 μm in Z. Washing in isopropanol and photocuring for 5 h. , Incorporation of 14wt% Quaternary Ammonium Methacrylate (QA_C 12 ) and 25wt% QA- containing polymer (pQA_C 12 ). , QA_C12 was synthesized with DMAEMA and HEMA (pQA). 14 wt% UDMA/GDMA/ QA_C12: mix of 50 mol% UDMA, 36 mol% GDMA and 14 mol% QA_C12. 25 wt% pQA_C12: mix of > 40 wt% of UDMA, 55 wt% of GDMA, 25 wt% of pQA. , Molar teeth, crowns, dental splint, and orthodontic retainers. , Contact-killing against Streptococcus mutans evaluated with and without salivary film. Bacterial suspensions (30, 300, and 3000 bacteria/cm−2) were dropped at the samples in 3M Petrifilm aerobic count plates. Biofilm formed for 6 days on the sample’s surfaces was stained and evaluated by CLSM. , 14 wt% UDMA/GDMA/QA_C12 and 25 wt% UDMA/GDMA/pQA_C12 showed more efficacy against S. mutans than UDMA/GDMA..
