Oral Myiasis is a rare disease that is mostly reported in developing countries. It is primarily caused by the invasion of the human body by fly larvae. The phenomenon is well-documented in the skin, especially among animals. This case report describes the presentation of Oral Myiasis caused by Musca Nebulo (common house fly), in a 28-year-old patient, with recent maxillofacial trauma. The patient was treated by manual removal of the larvae, after topical application of turpentine oil, followed by surgical debridement and oral therapy with Ivermectin.

Context:Walking bleach technique uses 30% hydrogen peroxide and sodium perborate, and this paste mixture causes loosening of the coronal temporary restorative materials and thus decreasing its clinical effectiveness and causing irritation to the patients oral tissues. In the present study, sealing ability of hygroscopic coronal temporary restorative materials were compared with the other commonly used temporary restorative materials.Aim:To evaluate the effects of walking bleach material on the marginal sealing ability and coronal microleakage of the hydrophilic temporary restorative materials with that of the other commonly used temporary restorative materials in endodontic practice.Materials and Methods:Seventy-five extracted human maxillary central incisor teeth were prepared chemo-mechanically and obturated with gutta-percha in lateral condensation technique. Surface of each tooth was double coated with cyanoacrylate glue. All the teeth were randomly divided in to five groups. Out of 15 teeth in each group, 10 teeth served as experimental specimens, in which bleaching agent was placed in the pulp chamber and 5 teeth served as control, in which no bleaching agent was placed. The access cavities were restored with temporary restorative materials being tested per each group respectively. The specimens were then immersed in 1% India ink dye and subjected to thermo cycling for 7 days. All the teeth were longitudinally sectioned and observed with stereomicroscope and were graded according to the depth of linear dye penetration.Statistical Analysis Used:Mann-Whitney U test and Kruskal-Wallis test.Results:Hydrophilic temporary restorative materials Cavit G and Coltosol F have shown minimal coronal dye leakage with better sealing ability when exposed to walking bleach paste mixture in the dye penetration tests compared to other commonly used temporary restorative materials.Conclusion:Marginal sealing ability of Cavit G and Coltosol F were not influenced by the effects of bleaching agent compared to other temporary restorative materials used in the study.

MTAD is biocompatible with superior antimicrobial efficiency compared to other commonly used root canal irrigants.
