“…These methods include incorporation of disinfectants into dental casts and disinfection of casts using a microwave oven in controlled settings . Microwave disinfection is an effective, quick, easy, inexpensive and versatile method, which can be done by dentists, assistants, and technicians . Autoclaving of the dental cast damages the surface of the dental cast, and immersion of the cast in chemical disinfectant dissolves gypsum, thereby decreasing the compressive strength.…”

The goal of disinfection in the dental office is to prevent the spread of infection from one patient to another and maintain the safety of the dental care providers. Prevention of cross infection has significant effect on infection control. The standard procedure of rinsing impressions under tap water immediately after removal from the mouth eliminates microorganisms along with saliva and blood. A broad search on published literature was done using the keywords impression materials, disinfection method, and sterilization of dental impression from 1980 to 2016 in Medline, Google Scholar, the internet, and textbooks. This article critically analyzes the various published methods of dental impression disinfection in dentistry.

“…6,8,10 Penggunaan energi microwave lebih dipertimbangkan untuk desinfeksi gigitiruan dibandingkan desinfeksi dengan bahan larutan kimia karena dapat membunuh beberapa mikroorganisme, waktu desinfeksi lebih singkat, dapat mencegah denture stomatitis, tidak memerlukan penyimpanan khusus, tidak mengubah warna atau bau, dan tidak menimbulkan reaksi alergi. 7,8,[11][12][13] Konsep yang penting dalam proses penggunaan microwave adalah bahwa pemanasan microwave merupakan konversi energi, bukan pemanasan seperti pada oven konvensional. 8 Pada penelitian terdahulu dinyatakan bahwa sterilisasi gigitiruan terhadap C.albican dan Streptococcus gordonii dapat dilakukan selama 2, 4, 6, 8 dan 10 menit dengan daya 650 Watt menggunakan microwave rumah tangga yang belum dimodifikasi.…”

“…8 Pada penelitian terdahulu dinyatakan bahwa sterilisasi gigitiruan terhadap C.albican dan Streptococcus gordonii dapat dilakukan selama 2, 4, 6, 8 dan 10 menit dengan daya 650 Watt menggunakan microwave rumah tangga yang belum dimodifikasi. 12 Penelitian yang berbeda mengemukakan bahwa desinfeksi menggunakan microwave selama 3 menit pada 650 Watt dapat mensterilisasikan bahan yang terkontaminasi dengan C.albican, Pseudomonas aeroginosa, Bacillus subtilis dan Staphylococcus aureus, 14 sedangkan sterilisasi gigitiruan akrilik dengan menggunakan microwave disertai dengan perendaman dengan air selama 3 menit pada 650 Watt dapat membersihkan segala jenis Candida. 15 Kekuatan transversal adalah salah satu sifat mekanik penting yang harus dimiliki basis gigitiruan untuk dapat bertahan agar tidak patah disebabkan beban pengunyahan yang besar.…”

Disinfectant by microwave energy is highly recommended as a solution to solve the problem of chemical disinfection on denture bases. One of the denture base materials is heat cured acrylic resin. Aim, to evaluate the effect of disinfectant by microwave energy with different time on the transversal strength of heat cured acrylic resin. 30 plates (n = 6) of heat cured acrylic resin with size 65x10x2,5 mm were divided into 5 groups (control; and microwave energy disinfected for 2, 4 , 6, and 8 minutes with 650 Watts of power). Transversal strength test was carried out using Torsee's Electronic System Universal Testing Machine with a test speed of 0.1 mm / second, and a load cell of 50 kgf. Data analyzed using one-way ANOVA and LSD pos hoc. Results, there were significant differences in the transverse strength among all groups (p <0.05). Mean values of all groups were 103.59 ± 0.66 MPa; 112.02 ± 2.10 MPa; 117.48 ± 1.73 MPa; 125.46 ± 2.25 MPa; and 135.89 ± 1.56 MPa respectively. Conclusion, the longer it is disinfected by microwave energy, the higher the transversal strength of heat cured acrylic resin.

“…Other papers [10][11][12][13][14][15] concluded that virtually every laboratory procedure is an ever present hazard of infection transmission, hence the dental practitioner has a legal and ethical responsibility to prevent and control infections in patients and staff members [16]. Powell et al [12] observed that two thirds of all the materials received in the laboratories, including dentures, were contaminated with pathogenic microorganisms.…”

In this paper we aim to perform a cross section morphological characterization of an acrylic polymer used for dental prostheses subjected to microwave disinfection. The method was largely investigated and the microbiological effectiveness is well established, but there are some issues regarding the in-depth alteration of the material. In our research, the surface roughness is insignificant and the samples were not polished or refined by any means. Two groups of 7 acrylic discs (20 mm diameter, 2 mm thickness) were prepared from a heat-cured powder. Half of the samples embedded a stainless steel reinforcement, in order to observe the changes at the interfaces between the polymer and metallic wire. After the gradual wet microwave treatment, the specimens -including the controls -were frozen in liquid nitrogen and broken into pieces. Fragments were selected for gold metallization to ensure a good contrast for SEM imaging. We examined the samples in cross section employing a high resolution SEM. We have observed the alterations occurred at the surface of the acrylic sample and at the interface with the metallic wire along with the increase of the power and exposure time. The bond configuration of acrylate samples was analysed by FTIR spectrometry.
