Introduction: Since literature provides various schools of thought to achieve Posterior Palatal Seal (PPS) in a maxillary denture, it becomes essential to know the techniques dominating in our curriculum presently. Aim: To determine the prevalence of concepts and also the need for standardisation in establishing PPS among dental colleges of Karnataka. Materials and Methods: A descriptive survey was conducted among teaching faculty of Department of Prosthodontics with varied teaching experience across the dental colleges of Karnataka. A pre-tested questionnaire containing ten close ended questions was distributed to 230 faculty members with MDS qualification in Prosthodontics via e-mail. The faculty responses were divided into three groups based on teaching experience: Group 1 (2-7 years), Group 2 (7-12 years) and Group 3 with more than 12 years of teaching experience. The Chi-Square Goodness of Fit test was used to compare the overall differences in the responses by the study participants; and Independent Chi-Square test to compare the differences in the responses based on teaching experience of the study participants. A value of p<0.05 was considered as statistically significant. Results: The most common method taught for locating vibrating line was Phonation-Nose Blowing-Fovea Palatini (46.0%). Two-line concept of vibrating line was taught (77%) more commonly, where the termination of maxillary denture is on posterior vibrating line (58%). Currently, Boucher’s conventional method without master cast scoring (63%) was the most favoured method to record the seal. This was true mainly with Group 1 (81.9%) and Group 2 (66.7%). In contrast, Group 3 faculty largely advocated Boucher’s conventional technique along with master cast scoring (70%). Overall most of the faculty members (66.5%) did not make the students score the postpalatal area. This was mainly seen in faculty belonging to Group 1 (81.9%) and Group 2 (69.7%). Bulk of Group 3 faculty (75%) taught scoring of the master cast. A large portion of the faculty (60.0%) recommended standardisation in the methods of teaching PPS which was mainly backed by Group 2 (77.3%) and Group 1 (61.7%). Conclusion: This survey indicates that among dental colleges of Karnataka, a majority of faculty of Prosthodontics prefer Boucher’s conventional method without master cast scoring (63%) to achieve maxillary PPS. Nevertheless, teaching concepts differed based on faculty experience. It is emphasised that teaching methods should be standardised and include unambiguous techniques.

Discovery of new polymeric materials suitable for prolonging the drug release, and the improvement in therapeutic efficiency and safety achieved by these delivery systems. Now-a-days the technology of controlled release is also being applied to veterinary products. The aim and objective of our current research is to formulate floating and bio adhesive formulations of ciprofloxacin for its controlled delivery to the duodenum which is its best absorption site, thus the oral bioavailability of ciprofloxacin could be improved by using direct compression technique. The experimental results was revealed that the all formulated tablets were of good quality with regard to hardness (3.7-4 kg/cm2), thickness (0.3-0.35 cm), density (~ 1 g/cm3), weight variation (1.3-4.2) and drug content (> 90%). As the result of floating capability study increasing the effervescent base of tablets from 5% to 10% significantly lower the lag time of floating (From about 6 min to 1.5 min) as well as floating duration (From about 21 hrs to 10 hrs). Invitro drug release showed (Fig. 1) that all formulation released 80% of the ciprofloxacin hydrochloride in 12 hrs study period. It was found that all the formulations were statistically significant (p ≤ 0.05).
