“…This proven correlation is directly attributed to the potential of water absorption and the porous nature of the 3D-printed resin material. This became a major concern, as learned, in the present study due to the prolonged immersion in each respective disinfectant for 20 minutes, leading to the high possibility of absorption into the surgical guide material (3)(4)(5). Subsequently, the high viscosity of VCO could explain why it displayed minimal morphological changes, in comparison to GA and EA trials, which absorbed more easily into the surface area of the guides.…”

“…As it will surely be exposed to blood, bone, and oral tissues during invasive implant procedures, it is categorized as a semi-critical product, which can be contaminated with various microorganisms during production, or in transition from/to, the dental laboratory (3). Owing to the nature of the resin material, from which stereolithographic surgical guides are usually made, they are known to be porous, water absorbable, and heat-sensitive, that being so, they may undergo deformation during steam sterilization (3)(4)(5). The application guide suggested the use of Ethyl Alcohol(EA), or nonchemical products for the disinfecting process (1,6).…”

INTRODUCTION:Disinfection of surgical guides is mandatory for intraoperative use. Virgin Coconut Oil may be a potent alternative disinfectant; however, its effect has not been fully discussed in dentistry. OBJECTIVES: To evaluate the dimensional accuracy of surgical guides after immersion in three disinfectants: 100% Virgin Coconut Oil (VCO), 2% Glutaraldehyde (GA), and 70% Ethyl Alcohol (EA) and estimate the antimicrobial potential of these three disinfectants. MATERIALS AND METHODS: Thirty identical surgical guides were printed and cut into two halves. The first half was scanned before and after disinfection-disinfection scanned files were compared to post-disinfection ones for the evaluation of the dimensional accuracy. The second half was immersed in sterile distilled water as the control groups for the estimation of the antimicrobial potential of the tested disinfectants. The comparisons between the three study groups were done using the One-Way ANOVA test. RESULTS: At the morphological assessment of the dimensional accuracy, group VCO was the most accurate with the lowest mean deviation value of 0.12 ± 0.02mm and root mean square value of 0.12 mm, group GA and group EA were less accurate with mean deviation value of = 0.22 ± 0.05mm and = 0.19 ± 0.03mm and root mean square value of 0.22 and 0.20 respectively (P < .001). For the antimicrobial potential, the tested disinfectants showed 100% of reduction in the mean microbial counts. CONCLUSIONS: Virgin Coconut Oil showed higher dimensional accuracy of the guides than Glutaraldehyde and Ethyl Alcohol. The antimicrobial potential was the same between the three disinfectants.

Background/objectives Disinfection of surgical guides is mandatory for intraoperative use. Virgin Coconut Oil may be a potent alternative disinfectant; however, its effect has not been fully discussed in dentistry. The objectives of this study were to compare the morphological and the volumetric dimensional changes of 3D printed surgical guides after immersion in three disinfectants: 100%Virgin Coconut Oil, 2% Glutaraldehyde, and 70% Ethyl Alcohol and to assess the antimicrobial effectiveness of the tested disinfectants. Materials and methods A surgical guide was designed using open platform software to print thirty guides and then cut them into two halves (N = 60). Pre-disinfection scans of the first half of the three study groups (n = 30) were performed using Cone-beam Computed Tomography, then immersed for 20 min in three disinfectants as follows: group VCO was immersed in 100% Virgin Coconut Oil, group GA was immersed in 2% Glutaraldehyde, and group EA was immersed in 70% Ethyl Alcohol. Post-disinfection scans of the first half of the three study groups (n = 30) were performed and then compared morphologically and volumetrically using an analyzing software program The second half of the three control groups (n* = 30) were soaked for 20 min in sterile distilled water as follows: group VCO*, group GA*, and group EA* for the assessment of the antimicrobial effectiveness of the three tested disinfectants. Results At the morphological assessment of the dimensional changes, group VCO were the most accurate with the lowest mean deviation value of 0.12 ± 0.02 mm and root mean square value of 0.12 mm, group GA and group EA were less accurate with mean deviation value of = 0.22 ± 0.05 mm and = 0.19 ± 0.03 mm and root mean square value of 0.22 and 0.20 respectively (p < 0.001). At the volumetric assessment, group VCO showed lower volumetric changes with a mean deviation value of 0.17 ± 0.10 mm, root mean square value of 0.19 mm, than group GA with mean deviation value of 0.23 ± 0.10 mm, root mean square value of 0.25 mm and group EA with mean deviation value of 0.27 ± 0.11 mm, root mean square value of 0.29 mm, however, no statistically significant differences were found between the three study groups (p = 0.10). The antimicrobial effectiveness of the three tested disinfectants showed a hundred percent (100%) reduction in the total microbial count in the first half of the three study groups treated with the three disinfectants revealing no bacterial growth, however, statistically significant differences were found between the second half of the three control and the first half of the three study groups. (p < 0.001). Conclusions Virgin Coconut Oil showed higher morphological dimensional accuracy of the tested surgical guides than Glutaraldehyde and Ethyl Alcohol without causing any volumetric dimensional changes in the 3D printed surgical guides after disinfection for 20 min and the antimicrobial effectiveness was the same between the three tested disinfectants without showing any microbial growth.
