In the Dentistry’s Prosthodontics clinic<br>manual, dental students should perform disinfection but no specific method was<br>recommended. This study utilized the True experimental research design to evaluate the<br>effectiveness of two ethyl alcohol disinfection methods (spray and immersion) in the<br>reduction of the bacterial colony count on dental casts and when running tap water is used to<br>rinse the dental casts. Informed consent from the 34 participants was first secured from each<br>of them. They were purposively selected based on their age and if they were partially<br>edentulous with at least ten teeth present in each arch. Sixty eight dental casts were produced<br>after the impression taking of both their maxillary and mandibular arches, 34 of which were<br>for the experimental group and 34 were for the control group. The Streaking Plate Technique<br>was used in determining the bacterial colony count on each dental cast before and after the<br>disinfection. The results were analyzed statistically using one-way ANOVA. Results revealed<br>that both the immersion and spray methods in which 70% ethyl alcohol was used as a<br>disinfectant, were found to be independently effective as compared with tap water rinsing<br>only in reducing the bacterial colony count of each dental cast. However, when the two ethyl<br>alcohol disinfection techniques were compared to each other, results showed that there were<br>no significant statistical differences between them when the ability to reduce the bacterial<br>colony count on dental casts was observed. From the conclusions, it is recommended that the<br>Dentistry students consider using either the immersion or spray method with 70% ethyl<br>alcohol as a disinfectant on dental casts. Further studies may also be done to test different<br>kinds of alcohols with various concentrations.</p>}, number={1}, journal={Abstract Proceedings International Scholars Conference}, author={Mendoza, Diane Sumagpang and Palad, Catherine Jill Dequito and Likot, Mae Louise Romero and Rodrigo, Jason Anthony Bernabe and Gatchalian, Deborah Cynthia Teodoro}, year={2019}, month={Dec.}, pages={288-296} }
