Abstract

Background: Irreversible hydrocolloid materials are widely used for both diagnostic and definitive impression procedures. Impressions can be disinfected by immersion or spraying in any compatible disinfectant. Disinfectants should not adversely affect the dimensional stability of the impression and physical properties of impression material and subsequent dental cast.

Objective: The study aims to evaluate the efficacy of a hypochlorous disinfectant solution mixed with irreversible hydrocolloid on setting time, antibacterial efficacy, and dimensional stability.

Methodology: Three groups were made with one control group and three alginate impression was made for each participants in the maxillary arch with 24-hours intervals between one another using the same brand of commercially available chromatic alginate. The working and setting time were noted. Bacterial swabs were collected using a dry sterile cotton swab in the mid palatal region. Dental casts were made using type III gypsum.

Result: The working and setting time had significant differences whereas the dimension among the cast has no significant difference. Microbial growth analysis had distinct differences among the groups.

Conclusion: The self disinfection method using a pioneer solution of hypochlorous HOCl (100 ppm) to mix the alginate impression material rather than the water with the same powder-liquid ratio prescribed by the manufacturer had the same dimensional stability with improved antimicrobial action.

新型自消毒液在不可逆水胶体印模材料中的功效评估--一项实验研究。
背景:不可逆水胶体材料广泛用于诊断性和确定性印模程序。可通过浸泡或喷洒任何兼容的消毒剂对印模进行消毒。消毒剂不应对印模的尺寸稳定性、印模材料的物理性质以及随后的牙科铸模造成不利影响:本研究旨在评估次氯酸消毒剂溶液与不可逆水胶体混合后对凝固时间、抗菌效果和尺寸稳定性的影响:使用同一品牌的市售色素藻酸盐,为上颌牙弓的每位参与者制作三个藻酸盐印模,每个印模之间间隔 24 小时。记录工作时间和凝固时间。用干的无菌棉签在腭中部区域采集细菌拭子。使用 III 型石膏制作牙模:结果:石膏的工作时间和凝固时间有显著差异,而石膏的尺寸没有显著差异。微生物生长分析在各组之间存在明显差异:结论:使用次氯酸 HOCl 先驱溶液(100 ppm)混合海藻酸盐印模材料,而不是制造商规定的相同粉液比例的水进行自我消毒的方法,具有相同的尺寸稳定性和更好的抗菌作用。
