Attitude, Management and Practice of Materials and Techniques for Measuring Posterior Palatal Seal Area with Dentists Working in Salah El-din

Background: The most crucial structure supporting the retention of maxillary complete denture is the posterior palatal seal area PPS. If it isn’t properly recorded, the seal could break. Purpose: To find out the perception for materials techniques that employed for recording PPS and its importance among dental practitioners. Methods: 15 questions in a questionnaire about this area were prepared. 75 participants from different places. The data were analyzed using Excel for Microsoft 2013. Results: Percentages of answers about significance of PPS were showed 85.4%of participant lack the knowledge of how to locate vibrating line.70.6% they said that the anterior vibrating line triangle in shape. 60% answered positively about if soft palate classification affects the prognosis of the case. 41.4% were preferred conventional technique, 54,6% said that fluid wax technique is the least accurate technique and 76% said that between immovable and movable part of the soft palate is the position of posterior vibrating line, 46.6% preferred orb end of (dental T-burnisher), 68.6% said that they can do re-posdaming. 76% used indelible pencil, 48%said that CL I is the most common variation of soft palate. 58.6% said that retention increases with greater post dam, 34.6% selected hamular notch as the most compressible area, 50.6% said that the antero-posterior width of posterior palatal seal is 5-8mm. Finally, hamular notch and post palatal seal tale 65% for the question about the region of the PPS area. Conclusion: Techniques and materials for PPS registration differs between participants. The most favorable was a conventional method.
