Introduction: Lateral throat form plays an important role in the success of lower complete denture as it affects its retention and stability. The length and thickness of lower dentures should be properly established in this region. Aim of this study is to evaluate the difference in the extension of lateral throat form between the patient's mouth and lower dentures. Materials and Methods: The lateral throat form was classified according to Neil's classification into Class I, Class II and Class III. The length of the lateral throat form was measured in the patient's mouth and in lower dentures with the help of UNC periodontal probe, and a comparison was made between them. Results: Among all the patients in this study, Neil's Class I lateral throat form was 53%, Class II was 37% and Class III was 10%. The average variation between the extent of lateral throat form intraorally and in lower denture at the anterior edge of the retromolar pad was 1.7 ± 1.75 mm in the right side and 2.5 ± 2.00 mm in the left side, whereas at the posterior edge of retromolar pad, it was 2.23 ± 1.92 mm in the right side and 3.06 ± 2.25 mm in the left side. Conclusions: The proportion of Neil's Class I was the highest followed by Class II and Class III was the lowest. The difference between the length of lateral throat form in the patient's mouth and in lower denture was statistically significant (P < 0.05).

Introduction: - Long term soft liners (acrylic and silicone based) are used to prevent damage to the abused mucosa, but they have the disadvantage of becoming porous with time leading to a suitable environment for opportunistic infections. This study was aimed to examine the inhibitory effect of incorporation of antifungal drug clotrimazole into long term denture soft liners on the growth of Candida albicans in vitro and evaluate the change in the surface hardness of soft liners.Materials and Method: The present study was done for two different long term soft liners, acrylic based (Permasoft) and silicone-based (Mollosil), by addition of clotrimazole drug in their minimum inhibitory concentration. The properties –zone of inhibition and surface hardness(Shore A) were evaluated at time intervals of 1,7,14,21,35 and 42days. A total of 224 samples were prepared. The properties were analyzed and inter group and intra group data was analyzed statistically by using One way ANOVA, Tukey post hoc-test and Paired t test.Result: The results showed significant creation of zone of inhibition for samples containing clotrimazole with the zone of inhibition decreasing with time. The surface hardness of all the samples increases with time.
