Application of topical powdery substances to the wound is an age old practice. Talc containing powdery substances are however commonplace and predominant in our environment. ⋯ We present a case report of a fifty-year-old man with prolonged application of talc containing powdery substances to the left thumb wound and excitation of exuberant granuloma mimicking squamous cell carcinoma. He had complete excision of the mass and satisfactory first dorsal metacarpal artery flap coverage of the soft tissue defect.

Composite resins are among the most popular restorative dental materials because of the strength and esthetic properties. The goal of this study was to assess the effect of commonly consumed beverages on microhardness and color stability of microhybrid (MH) and nanofilled NF) composite resins. ⋯ Both composite materials (I and II) showed a reduction in microhardness and change in color after immersion in a different type of test media.

Residual monomers released from composite resins have cytotoxic, mutagenic, and estrogenic effects. Mode of polymerization and application thickness are important for monomer release. ⋯ This study revealed that the amount of residual monomers released from bulk-fill composites was affected by layer thickness and polymerization time.

Dental caries is one of the most common diseases seen in the oral cavity in all periods of deciduous, mixed, and permanent dentition. A comprehensive study of the oral microbiome is required to understand its polymicrobial etiology. The aim of this study was to reveal the plaque microbiome of caries-active and caries-free adults. ⋯ The present study provides comprehensive knowledge of the microbiological etiology of caries in permanent dentition.

Hydatid cyst is an endemic disease especially in underdeveloped and developing countries, affecting mostly the liver and lungs. However, a wide range of unusual anatomical sites in the abdomen have been reported, including the spleen, pancreas, kidney, and ovaries as well as dissemination within the abdominal and pelvic cavities. ⋯ In this article, we present a case of primary left-sided colon hydatid cyst, resected laparoscopically with the affected intestinal segment. The diagnosis of hydatid cyst was made by macroscopic and microscopic examinations.
