“…While the main advantage of SSCs is the functional durability, the main challenge of SSCs is esthetic concern, especially when used in the anterior esthetic zone [ 8 ]. In addition, SSCs have been shown to exhibit corrosion, allow growth of bacterial biofilm, and possibly harbor certain pathological bacteria [ 13 ]. More recently, there has been an increase in the use of prefabricated zirconia crowns which offer an esthetically superior alternative to SSCs.…”

This study compared the laser and rotary removals of prefabricated zirconia crowns in primary anterior and permanent posterior teeth. Sixty-two extracted teeth were prepared for prefabricated zirconia crowns cemented with resin-modified glass-ionomer cement. Specimens underwent crown removals by a rotary handpiece, or erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser. Pulpal temperatures, removal times, and scanning electron microscopy (SEM) examinations were compared. The average crown removal time for rotary and laser methods was 80.9 ± 19.36 s and 353.3 ± 110.6 s, respectively, for anterior primary teeth; and 114.2 ± 32.1 s and 288.5 ± 76.1 s, respectively, for posterior teeth (p < 0.001). The maximum temperature for the rotary and laser groups was 22.2 ± 8.5 °C and 27.7 ± 1.6 °C for anterior teeth, respectively (p < 0.001); and 21.8 ± 0.77 °C and 25.8 ± 0.85 °C for the posterior teeth, respectively (p < 0.001). More open dentinal tubules appeared in the rotary than the laser group. The rotary handpiece removal method may be more efficient than the laser with lower pulpal temperature changes. However, the laser method does not create noticeable tooth or crown structural damage compared to the rotary method.

Plasma treatment effects on destruction and recovery of Porphyromonas gingivalis biofilms

et al. 2022

The objective of this study was to investigate the treatment effects of non-thermal atmospheric gas plasmas (NTAP) on destruction and the recovery (or re-colonization) of Porphyromonas gingivalis (P. gingivalis) in biofilms. P. gingivalis is a well-known keystone periodontal pathogen strongly associated with periodontal diseases, especially periodontitis. P. gingivalis biofilms were formed on stainless steel coupons and treated for 1, 2, and 5 minutes by NTAP of pure argon gas and argon+oxygen gas mixture. MTT assay, colony forming unit (CFU) counting assay and confocal laser scanning microscopy (CLSM) were used to assess the destruction efficiency. In addition, the plasma treated biofilms were re-cultured in the medium supplemented with antibiotics and oxidative stress sources to determine the synergy of the NTAP with other antimicrobial agents. The results showed the plasma treatment could result in 2.7 log unit reduction in bacterial load. The recovered biofilm CFU with NTAP treatment combined with sub minimal inhibition concentration of amoxicillin was 0.33 log units less than the biofilm treated with amoxicillin alone. The recovered biofilm CFU in NTAP groups was about 2.0 log units less than that in the untreated controls under H2O2 treatment. There was approximately 1.0 log unit reduction of biofilm CFU in plasma treated biofilm compared with untreated control under paraquat treatment. The plasma treated biofilms exhibited less resistance to amoxicillin and greater susceptibility to hydrogen peroxide (H2O2) and paraquat, suggesting that NTAP may enhance biofilm susceptibility to host defense. These in vitro findings suggested that NTAP could be a novel and effective treatment method of oral biofilms that cause periodontal diseases.

The biocorrosion of pure zinc by sulfate reducing bacterium (SRB) Desulfovibrio vulgaris was found to be very severe (2.3 ± 0.1 mm/y) after 7 d incubation in 100 mL of ATCC 1249 medium at 37 °C in 125 mL anaerobic vials. D-tyrosine was evaluated as a biocide enhancer for the 2,2-dibromo-3-nitrilopropionamide (DBNPA) biocide mitigation of microbiologically influenced corrosion (MIC). The 100 ppm (w/w) DBNPA alone treatment was found to reduce the SRB sessile cell count by 2-log, zinc weight loss by 48%, and corrosion pit depth by 86%. This biocide treatment was enhanced by its combination with 1 ppm Dtyrosine, which achieved 4-log sessile cell reduction, 70% zinc weight loss reduction, and 92% pit depth reduction compared with the untreated control. Headspace H 2 S concentrations confirmed that better biocide treatment led to less biogenic H 2 S. Electrochemical corrosion data supported weight loss and pit depth data.
