“…Shelburne et al ( 2003 ) reported a greater than 6 log reduction in adherent Streptococcus mutans bacteria with steam sterilisation of pre-veneered PMCs. Darshan et al ( 2019 ) demonstrated that contamination on stainless steel PMC that had been tried into the mouth was reduced effectively by steam sterilisation. The effectiveness of decontamination methods on PMCs was assessed via colony counts of Streptococcus mutans , Staphylococcus aureus , and Escherichia coli on selective media plates.…”

“…The benefits of reducing bacterial populations by steam autoclaving cannot be overstated. An in vivo study comparing decontamination methods on tried-in PMCs found autoclaving at 121 °C, 15 psi for 15 min significantly reduced the colony counts, compared with 5% sodium hypochlorite (5 min), 5% glutaraldehyde (5 min), 70% isopropyl (1 min), or glass bead groups (Darshan et al 2019 ). The insufficient reduction in bacterial counts for rapid chairside sterilisation (i.e., sodium hypochlorite, glutaraldehyde, etc.)…”

“…A recent paper concluded that steam sterilisation was the optimal protocol for sterilising preformed metal crowns (PMCs), compared with chemical disinfectants. 5 Chairside decontamination protocols were deemed ineffective and not safe for clinical practice. Steam sterilisation (autoclaving) can initiate crazing and cracking of PCs, thus exposing sites for pitting corrosion.…”

“…Relatively little past work has been done into the effects of sterilisation practices on paediatric PC. A recent paper concluded that steam sterilisation was the optimal protocol for sterilising preformed metal crowns (PMCs), compared with chemical disinfectants 5 . Chairside decontamination protocols were deemed ineffective and not safe for clinical practice.…”
