Titanium dioxide (TiO2), the golden standard among the photocatalysts, exhibits a varying level of photocatalytic activities (PCA) amongst the synthetically prepared and commercially available products. For commercial applications, superior photoactivity and cost-effectiveness are the two main factors to be reckoned with. This study presents the development of simple, cost-effective post-treatment processes for a less costly TiO2 to significantly enhance the PCA to the level of expensive commercial TiO2 having demonstrated superior photoactivities. We have utilized sequential calcination and ball milling (BM) post-treatment processes on a less-costlier KA100 TiO2 and demonstrated multi-fold (nearly 90 times) enhancement in PCA. The post-treated KA100 samples along with reference commercial samples (P25, NP400, and ST01) were well-characterized by appropriate instrumentation and evaluated for the PCA considering acetaldehyde photodegradation as the model reaction. Lattice parameters, phase composition, crystallite size, surface functionalities, titanium, and oxygen electronic environments were evaluated. Among post-treated KA100, the sample that is subjected to sequential 700 °C calcination and BM (KA7-BM) processes exhibited 90-fold PCA enhancement over pristine KA100 and the PCA-like commercial NP400 (pure anatase-based TiO2). Based on our results, we attribute the superior PCA for KA7-BM due to the smaller crystallite size, the co-existence of mixed anatase-srilankite-rutile phases, and the consequent multiphase heterojunction formation, higher surface area, lattice disorder/strain generation, and surface oxygen environment. The present work demonstrates a feasible potential for the developed post-treatment strategy towards commercial prospects.

Bacterial Disease

Actinomycosis is a rare invasive bacterial disease that is characterised by granulomatous inflammation often mistaken as malignancy. Traditionally, this has been managed with prolonged courses of antibiotics with durations up to 6–12 months. Surgical intervention as an adjuvant treatment has been shown to reduce the length of antibiotic treatment significantly to 4 weeks. We report a case of cervicofacial actinomycosis in a 12-year-old girl who was adequately treated with an 11-day course of antibiotics without surgical intervention and shows no signs of recurrence at 6 months post-treatment.

In recent months, the dental treatment scenario has changed due to the outbreak of the Covid 19 pandemic. Most of the aerosol generating procedures have been avoided. This case report, describes a conservative, less aerosol generating and cost-effective treatment modality, for the immediate aesthetic management of moderate fluorosis using enamel microabrasion technique.
