RESUMO
Introduction The debonding of acrylic teeth from the denture base, particularly in cases of prominent ridges, is a common problem faced by clinicians and patients. The present study was conducted to assess the effects of various chemical treatments on the shear bond strength (SBS) of acrylic teeth bonded to different high-impact denture base materials. Materials and methods The present in vitro study was conducted on 80 wax specimens with acrylic teeth bonded to two high-impact denture base materials (DPI Tuff (DPI Dental Products of India Ltd, Mumbai) and Trevalon HI (Trevalon HI, Dentsply, Karnataka)). The two main groups were further divided into four subgroups of 10 specimens each, depending on the chemical treatment at the ridge lap area of the tooth: control group without any chemical treatment, chemical surface treatment (CST) with dichloromethane and monomer mix, CST with ethyl acetate, and CST with acrylic adhesive cyanoacrylate. The SBS was tested using a universal testing machine (UTM). Analysis of variance (ANOVA) and post-hoc Tukey tests were used for statistical analyses. Results The mean SBS of Group A (DPI Tuff) was 111.75 N as compared to 118 N in Group B (Trevalon HI). The differences were statistically significant (p<0.05). ANOVA and post-hoc Tukey's tests revealed significant differences between subgroups. The highest mean SBS was noted with a dichloromethane and monomer mix (1:1 volume), followed by the ethyl acetate, control, and cyanoacrylate subgroups. Conclusion The cross-linked acrylic teeth treated with a dichloromethane and monomer mixture (1:1 by volume), processed with Trevalon HI high-impact denture base resin had the highest SBS and thus were indicated for bonding teeth with the suggested denture base.
RESUMO
Currently, all of us are experiencing emotions, thoughts, and situations we have never experienced before. It is not that there were no pandemics earlier. In light of the COVID-19 pandemic, health issues are growing. It has shaken the entire world and created global panic. In a way, it is affecting oral health also. Taking care of oral health is as important as looking after physical health. There is a need for a range of treatments to anticipate oral health issues. Strategies to combat these oral health issues should use options like teledentistry to develop effective methods of support. How to cite this article: Kshirsagar MM, Dodamani AS, Dodamani GA, et al.

RESUMO
BACKGROUND: The COVID-19 (2019-nCoV) pandemic is a major threat to public health worldwide; it has been identified as originating in Wuhan, Hubei province, China. It has spread across the globe, causing an outbreak of acute infectious pneumonia. Such a global outbreak is associated with adverse effects on mental health. Fear, stress and anxiety seem more definitely an outcome of mass quarantine. METHODS: Keeping this pandemic situation in mind, existing literature on the COVID-19 crisis relevant to mental health was redeemed via a literature search from the PubMed database. Collected published articles were summarized according to their overall themes. RESULTS: Preliminary evidence suggests that symptoms of self-reported stress, anxiety and depression have a common psychological impact due to the pandemic, and may be associated with disrupted sleep. Regional, state and National-international borders have almost been shut down, economies crashed, and billions of people quarantined or isolated at their own homes and quarantine centers. In this situational frame of covid-19, patients, frontline health-care professionals anf geriatric population with existing psychiatric conditions may be encountering further suffering. CONCLUSION: COVID-19 will continue to affect mental health, which plays an important role in battling the epidemic. With the scare of the COVID-19 pandemic on the rise, it is time that psychiatrists should try to integrate the health-care services keeping mental health at prime.
