The aim is to evaluate and compare the flexural strength of different provisional restorative materials reinforced with glass and polyethylene fibers. A total of 90 samples were prepared and divided into three groups based on the type of fiber reinforcement, unidirectional S-glass (Splint-It) and ultra-molecular weight polyethylene (Ribbond). Unreinforced samples served as control group. Again each group was subdivided into three subgroups based on type of provisional restorative resins, heats cure polymethyl methacrylate, self-cure poly methyl methacrylate and self-cure bis-acryl composite. Samples were loaded in a universal testing machine until fracture occurs. The mean flexural strengths (MPa) were subjected to the one-way ANOVA, followed by the Tukey-HSD test at a significance level of 0.001. The result shows all the fiber reinforced samples possessed greater strength than the control samples. In control samples, the heat cure poly methyl methacrylate resin (72.74 ± 2.28 MPa) had the greatest flexural strength, followed by self-cure bis-acryl composite (67.05 ± 2.35 MPa) and self-cure poly methyl methacrylate resin (52.88 ± 1.90 MPa). In both heat and self-cure poly methyl methacrylate resin, the polyethylene fiber reinforcement (96.00 ± 2.63 MPa, 86.17 ± 1.92 MPa) provides the greatest strength than glass fiber reinforcement (92.68 ± 1.58 MPa, 76.40 ± 2.11 MPa). In self-cure bis-acryl composite, the glass fiber (105.95 ± 3.07 MPa) shows better reinforcement than polyethylene fiber (99.41 ± 1.74 MPa).The fibers reinforcement increases the flexural strength of provisional restorative resins.

Purpose Different socio-demographic variables, such as age, gender, and systemic disease, may affect satisfaction with complete dentures. Several studies have failed to show strong correlations either between patient satisfaction with their dentures and their quality or between denture satisfaction and the quality of the denture-supporting tissues. Hence, this study utilized a standardized questionnaire that included questions from domains such as mastication, appearance, speech, comfort, health, denture care, and social status. These questionnaires were used to determine the level of complete denture satisfaction along with socio-demographic variables such as age, gender, and systemic condition. Materials and method A total number of 128 completely edentulous patients aged between 40 and 50 years were selected. A standardized questionnaire, with 19 questions based on denture satisfaction level and masticatory capacity in the domains of functional limitation (FL), psychological discomfort (D1), psychological disability (D2), and social disability (D3), was administered. All the questions were recorded on a scale of 2, 1, 0 based on satisfied, moderately satisfied, and not satisfied, whereas hardly ever, occasionally, and very often were used for masticatory capacity. Questions on denture satisfaction were asked based on the post-treatment satisfaction with the new maxillary/mandibular complete dentures of the patients. Results Based on gender, the distribution of samples was 46.09% for male patients and 53.91% for female patients among the 128 patients selected. Similarly, based on systemic diseases, 66.41% had the presence of systemic disease while 28.13% did not have any systemic disease. Around 5.47% of the sample did not have any medical records. The predominance of psychological satisfaction was more for female patients. Based on systemic disease, it was observed that patients with the presence of systemic disease (Pn) were more psychologically comfortable than those who did not have systemic disease. The predominance of functional satisfaction was not marked in both genders. Based on systemic disease, it was observed that patients with the presence of systemic disease (Pn) had less functional comfort on mastication than those who did not have a systemic disease. Conclusion The acceptance of and satisfaction with complete denture treatment were comparatively higher in patients who had a systemic disease than in those with a non-systemic disease in terms of psychological and social comfort, whereas, in functionality, patients with a non-systemic disease had a higher satisfaction level.

Carbon dioxide gas was used a s a physical blowing agent to produce medium density polypropylene foam sheets using a single screw extruder. The mechanical properties of the foam were similar in the machine direction and in the transverse direction. A better surface finish and a lower density foam was produced by using a commercial wrapping film a s a cap layer. The process conditions and die design data are presented in an attempt to relate to product characteristics.-I 1 J -I J

Angiolipoma is one of the rare variant of lipoma. This benign tumour consists of both fatty and vascular elements. It mostly occur in the trunk and extremities and is uncommon in head and neck region. Angiolipoma is classified as infiltrating and non- infiltrating types. Among all neoplasms of the oral cavity, lipomas account for 1 to 5% and the incidence of angiolipoma is 5 to 17% in it. There is no sex predilection for this tumour. It is classified as infiltrative and non-infiltrative type. Surgical excision is the method to be considered for both the types of angiolipoma, however the infiltrating type recurs post-surgery. We report a rare case report of 55-year-old female with non-infiltrating angiolipoma of the hard palate mimicking a mucocele treated by surgical excision with no signs of recurrence and good wound healing after three months follow up with minimal scar formation.

Objectives:To evaluate the in vitro growth inhibition of Candida albicans, in the soft-liner material and Shore A hardness from resin-based denture soft lining materials modified by neem or garlic incorporation.Materials and Methods:Resin discs were prepared with poly methyl methacrylate (PMMA) and soft liners incorporated with varying concentrations of neem or garlic. For antifungal activity, resin discs were placed on agar plates inoculated with C. albicans and were evaluated after 2, 4, and 7 days using the streaking method. The hardness of the PMMA was evaluated with the use of Shore A at 2, 4, and 7 days. Data were statistically processed by SPSS software (IBM Company, Chicago, USA) using Kruskal–Wallis test, and post hoc comparisons were done using Dunn's test. P <0.05 was considered statistically significant.Results:Neem and garlic added to PMMA soft liner had an inhibitory effect on C. albicans. Both the neem and garlic when added showed positive results against C. albicans when compared to the control group. The soft liner hardness increased statistically by time but not for the different plant extract concentrations.Conclusions:Within the limitations of this in vitro study, it was found that neem and garlic can be used as an additive to tissue conditioner to reduce the adherence of C. albicans without significantly affecting the hardness of the heat-polymerized acrylic resin.
