Background: Facial esthetics was primarily the subject of study for artists and philosophers. Facial appearance is an essential diagnostic criterion for a complete comprehensive orthodontic treatment planning. The aim of this study was to establish the perception of facial esthetics by different professionals, namely orthodontists, artists, and photographers, and to investigate the most influential facial characteristics involved in rating the overall attractiveness. Materials and Methods: Twenty-two subjects of age 18–24 years fulfilling the inclusion criteria were selected as the study samples. The subjects were asked to relax, gently touch the lips together, and then start smiling. This dynamic range of smile was video recorded using a digital camera. This video was then converted into 300 frames. The frame that best represented the subjects' natural/posed unstrained social smile was selected and cropped to create three types of images: the face with the smile, the face without the smile, and the smile image. The evaluators (orthodontists, artists, and photographers) were instructed to answer the questions from 1 to 8 looking at image 1 (face with smile), question 9 by looking at image 2 (face without the smile), and questions 10 and 11 by looking at image 3 (smile only). Results: According to orthodontists and artists, the feature most strongly associated with overall attractiveness was symmetry of face, whereas the photographers showed the highest score for cheekbones. The highest correlation was found between the orthodontist and artist groups. Conclusion: The perception by the three professionals confirms that the overall facial attractiveness is more important than dental attractiveness.

Background Knowledge of bone density in maxilla and mandible will allow the clinician to plan the anchorage strategies and placement of implants with necessary precautions. The study aims to evaluate the deflection changes of titanium alloy self-drilling mini implants from the intended path that occurs during placement in varying bone densities. Material and Methods 63 titanium alloy self-drilling mini implants of the lengths 6mm, 8mm, and 10mm with diameter of 1.3mm were placed in three homogenous solid rigid polyurethane foam (saw bone) with bone densities of 20pcf, 30pcf, and 40pcf simulating anatomic sites in maxilla and mandible. 7mini implants of each length in all bone densities were tested for study. The implants were inserted perpendicularly into artificial bone block held in a custom made stand. The bone blocks were then radiographically exposed and the deviation of the long axis of the implantfrom a true vertical line was measured. Results There was a decrease in deflection of the mini implant with increase in density. On the other hand, increase in length resulted in increase in the amount of deflection. Conclusions Longer mini implants can be used in less dense bone as in maxilla, whereas shorter mini implants can be used in high dense bone as in mandible to increase the stability and success rate of implants. Bone density and implant length play a role in deflection of mini implant from its intended path of insertion. Key words: Orthodontic Mini implants, deflection, bone density, anchorage.
