Perception of Complete Visually Impaired Children to Three Different Oral Health Education Methods: A Preliminary Study.

AIM: To evaluate the perception of visually impaired children to three different methods of oral health education. STUDY DESIGN: Sixty total visually impaired children were divided into three groups of 20 children each. Children in group-I received oral health education through a lecture. Children in group II received Demonstration on a Model by Tell and Touch method (DMTT) and children in group III were self trained on oral hygiene skills. All children received written instructions in Braille. Their knowledge and practice of oral hygiene methods were recorded by a questionnaire and their method of brushing and rinsing was assessed during a personal interview. Data obtained was subjected to statistical analysis. RESULTS: Children in group II were able to brush and rinse significantly better (p <0.05) as compared to the other groups. Demonstration on a Model by Tell and Touch method was found to be the most preferred method of oral health education. CONCLUSION: Oral health education given through DMTT method was perceived well by the visually impaired children.

Synthesis and biological activity of isoamoenylin, a metabolite of Dendrobium amoenum.

Isoamoenylin (6), a dihydrostilbene from Dendrobium amoenum, was synthesised from 3,4,5-trimethoxybenzaldehyde (1) in four steps with an overall yield of 60%. The spectral data for synthetic 6 are in good agreement with those of the natural product. Isoamoenylin showed moderate antioxidative and weak antibacterial activities.
