Item Anthropometric Evaluation of Facial Dimensions in Population of Western Maharashtra(Association of Medical Dental and Allied Sciences, 2016-06) Singh, Sneha; Phaphe, Sandesh; Ganiger, Chanamallappa; Pawar, Renuka; Ahammed, A.R. Yusuf; Mane, PratapObjective The present study was carried out to evaluate an average ratio between specific soft tissue parameters of the face among the young adult population of Karad, Maharashtra. The soft tissue parameters gauged in the present study are inner canthal distance, outer canthal distance, alar base width and distance between the corners of the mouth. Rationale The average ratio of soft tissue parameters of the face can act as a guideline for effective treatment of teeth and dento facial structures as well as soft tissue outlines. Materials and Methods 1,786 young adults aged between 18 and 20 years from Karad city were initially screened, out of which 1,000 were selected on the basis of the inclusion criteria. The fronto-facial photographs of the selected subjects were captured using a digital camera. The selected facial soft tissue parameters were digitally measured, and the data were subjected to statistical analysis. Result The values of the parameters measured were marginally more in males; however, the ratio among the parameters was similar in both the sexes. The average ratio between the inner canthal distance, alar base width and distance between corners of the mouth was found to be 1:1.3:1.7, and the average ratio between the outer canthal distance, alar base width and distance between the corners of the mouth was found to be 2.3:1:1.3. Conclusion The different parts of the human face exist in certain proportions. Establishing the ratio between these parameters is important to facilitate proper diagnosis and treatment planning for the specific population.Item To Evaluate the Shear Bond Strength of Bondable Molar Tubes by Two Enamel Conditioning Techniques(Akshantala Enterprises Private Limited, 2020-08) Ganiger, Chanamallappa; Agarwal, Nidhi; Pawar, Renuka; Phaphe, Sandesh; Ahammed, Yusuf; Mane, Pratap; Patil, Sahil; Sathe, TanujaShear Bond Strength (SBS) is considered to be the main factor in the evolution of bonding. The bracket bond strength should withstand the forces during the orthodontic tooth movement. The commonly used technique by Orthodontists is to attach the brackets to the enamel surface is the acid-etch bonding technique along with 37 % phosphoric acid as etchant. With time, a new technique emerged in orthodontics which is used before bonding for the primary preparation of teeth as well as for the purpose of increasing bond strength known as Sandblasting. This study was done to compare the shear bond strength of acid etching and air abrasion technique used in orthodontic practice. MethodsA total of 100 extracted human first molar teeth were selected and segregated into 4 groups of 25 teeth. Group I: bonding without enamel preparation, Group II: using acid etching with 37 % phosphoric acid, Group III - sandblasting with 50 μ aluminium oxide, Group IV - sandblasting with 100 μ aluminium oxide. These 100 samples were then subjected to the measurement of the shear bond strength with an Instron machine and was measured in Newtons. ResultsGroup 1 showed a mean shear bond strength of 7.21 ± 0.29; for group II it was 7.77 ± 0.53; for group III it was 8.3 ± 0.3 and for group IV it was 10.04 ± 0.45. Groups 2 and 3 and groups 2 and 4 showed statistically significant difference. Shear bond strengths of both the groups 3 and 4 showed highly statistically significant difference. Conclusions100 µ aluminium oxide group showed the highest Shear Bond Strength. On inter group comparison, sandblasting with aluminium oxide was found to have better shear bond strength compared to conventional acid etching techniques.
