PURPOSE. The purpose of this study was to determine accurately the part of the tragus to be used to form the Ala-Tragal line or Camper’ line in orthognathic profile patients. MATERIALS AND METHODS. 150 dentate subjects with age of 18-40 years with orthognathic profile were sampled. Life-size lateral digital photographs of the face with fox plane were taken in natural head position. Different angles between Eye-Ear plane and occlusal plane (OT1-OP), Eye-Ear plane and ala-superior border of tragus (OT1-AT1), Eye-Ear plane and ala-middle border of tragus (OT1-AT2) and Eye-Ear plane and ala-inferior border of tragus (OT1-AT3) were calculated using computer software package, AutoCAD 2004. From the three angles formed by the Eye-ear plane (OT1 or FH plane) and the ala-tragal lines, the one closest to the angle formed between Eye-Ear plane (OT1) and occlusal plane (OP) was used to determine the occlusal plane of orientation. The obtained results were subjected to ANOVA F test, Tukey’ Honestly significant difference test, followed by Karl Pearson coefficient of correlation test. P values of less than 0.05 were taken as statistically significant. RESULTS. The mean of base line angle i.e. OT1-OP angle (11.96 ± 4.36) was found to be close to OT1-AT2 angle (13.67 ± 1.93) and OT1-AT3 angle (10.31 ± 2.03), but OT1-OP angle was found to be more closer to OT1-AT3 angle. Comparison of mean angles showed that OT1-OP angle in both males (11.68) and females (12.51) is close to OT1-AT3 angle (males- 11.01, females- 11.95). CONCLUSION. The line joining from ala to the lower border of the tragus was parallel to the occlusal plane in 53.3% of the subjects. There was no influence of the sex on the level of occlusal plane.

In the recent past decade, layered bismuth metal oxides (Bi2MO6, M = W, Mo and Cr) have establishedsubstantial consideration comparable to bismuth oxyhalides (BiOX, X = Cl, Br, I and F) for its emergingpotential towards its photocatalytic applications in clean energy production and environmentalremediation. Their electronic band structure characterises appropriate band-gap for visible lightphotocatalytic activity. The photocatalytic activities of these materials can be deliberately incrementedusing various strategies including formation of heterojunction, modification of interface, usingsensitizers, metal and non-metal doping, development of composites, and formation of oxygenvacancies. Nevertheless, its visible light applications limit up due to higher recombination ofphotoinduced charge carriers. This review systematically encapsulates electronic spectra, strategiesimplemented for higher separation of charge carriers, and establishing its potential in thefield of cleanenergyproduction as well as degrading manageable and recalcitrant pollutants. Finally, the currentscenario and future aspects of using Bi2MO6 photocatalysts are summarised.
