Background: Fluorosis is an endemic disease prevalent in 22 states in India affecting 70 million individuals. The process of removal of fluoride ions from water is known as defluoridation. Even though several defluondation techniques have been developed and implemented in India, most of these techniques have many disadvantages. Development of a newer defluoridation technique starts With laboratory experimentation of materials. Objectives: To identify recent advances in laboratory studies in India with regard to the materials used for defluoridation (published from 2010-2017). Methodology: The review was carned out according to the Joanna Briggs Institute (J81) critical appraisal guideline. A three-step search strategy was utilized which yielded twenty articles after the final step. These articles were evaluated to describe, compare and contrast the materials (Chemical, indigenous and herbal) in terms of effectiveness of fluonde removal, critical pH, cost and other factors. Results: Fluoride removal capacity varied around to 100% and optimum pH between 2 to 10 in different studies. Indigenous and herbal materials are cost effective compared to chemicals. But chemicals have better defluoridation capacity. The defluondating properties can be enhanced using certain combinations or pretreatment of these materials (eg-Heat activation). Conclusions: Indigenous and herbal products are suitable for Indian conditions because of the ease of availability and cost-effectiveness. The future research should focus on enhancing the defluoridating properties of locally available materials and field studies regarding the feasibility in real life scenarios.
