This study compared and evaluated the effect of two desensitizing agents on the retention of cast crowns when cemented with various luting agents. Ninety freshly extracted human molars were prepared with flat occlusal surface, 6 degree taper and approximately 4 mm axial length. The prepared specimens were divided into 3 groups and each group is further divided into 3 subgroups. Desensitizing agents used were GC Tooth Mousse and GLUMA® desensitizer. Cementing agents used were zinc phosphate, glass ionomer and resin modified glass ionomer cement. Individual crowns with loop were made from base metal alloy. Desensitizing agents were applied before cementation of crowns except for control group. Under tensional force the crowns were removed using an automated universal testing machine. Statistical analysis included one-way ANOVA followed by Turkey-Kramer post hoc test at a preset alpha of 0.05. Resin modified glass iono...

This study compared and evaluated the effect of two desensitizing agents on the retention of cast crowns when cemented with various luting agents. MATERIALS AND METHODS. Ninety freshly extracted human molars were prepared with flat occlusal surface, 6 degree taper and approximately 4 mm axial length. The prepared specimens were divided into 3 groups and each group is further divided into 3 subgroups. Desensitizing agents used were GC Tooth Mousse and GLUMA � desensitizer. Cementing agents used were zinc phosphate, glass ionomer and resin modified glass ionomer cement. Individual crowns with loop were made from base metal alloy. Desensitizing agents were applied before cementation of crowns except for control group. Under tensional force the crowns were removed using an automated universal testing machine. Statistical analysis included oneway ANOVA followed by Turkey-Kramer post hoc test at a preset alpha of 0.05. RESULTS. Resin modified glass ionomer cement exhibited the highest retentive strength and all dentin treatments resulted in significantly different retentive values (In Kg.): GLUMA (49.02 ± 3.32) > Control (48.61 ± 3.54) > Tooth mousse (48.34 ± 2.94). Retentive strength for glass ionomer cement were GLUMA (41.14 ± 2.42) > Tooth mousse (40.32 ± 3.89) > Control (39.09 ± 2.80). For zinc phosphate cement the retentive strength were lowest GLUMA (27.92 ± 3.20) > Control (27.69 ± 3.39) > Tooth mousse (25.27 ± 4.60). CONCLUSION. The use of GLUMA � desensitizer has no effect on crown retention. GC Tooth Mousse does not affect the retentive ability of glass ionomer and resin modified glass ionomer cement, but it decreases the retentive ability of zinc phosphate cement. [

The success of rehabilitation treatment is closely related to an exact reproduction of occlusal relation in the articulator during all stages of treatment. This article describes a method of making an accurate interocclusal record when the most distal tooth is an abutment of a fixed partial denture. In this method a centric stop or vertical stop is prepared to maintain the vertical dimension of occlusion and to act as third point of reference for a stable occlusal relationship when occluding the definitive casts on articulators.

As a result of external environmental factors, facial prostheses may become discoloured and discolour by changing colour from intrinsic and extrinsic colouring, and this is associated with the intrinsic colour stability of elastomers and colourants. Thus, in this in vitro study, a comparative evaluation of the effect of outdoor weathering on the colour stability of A-103 and A-2000 room-temperature vulcanised silicones used for maxillofacial prosthesis was conducted. To accomplish this study, a total of 80 samples were fabricated, 40 samples of each material were grouped as clear (20) and pigmented (20). These samples were mounted on wooden board and the assembly was placed...

The study included 120 specimens divided into 8 groups of 15 samples each based on the combination of chemical surface treatment with either methyl methacrylate, ethyl acetate, or methylene chloride and chemical surface treatment of rounded joint, 45° bevel, and butt joint. Following surface treatment, dentures were repaired with self-cure resin. After treatment, to assess the transverse strength, they were subjected to a 3-point bending test. Surfaces that were fractured were assessed under the microscope and were analyzed to AutoCAD for assessing cohesive or adhesive failure type and the area was measured. The study results showed that a statistically significant difference was 2939 seen in most of the comparisons done. Specimens with rounded joints and methylene chloride used for 60 seconds showed the gain of strength of 60%-70& in the present study. The present study concludes that to attain better bond strength in a specimen repaired, the fractured segments of the specimens should be etched with methylene chloride for 60 s and should be given the rounded joints.

Displaceable, or ‘flabby ridges’, present a particular difficulty and give rise to complaints of pain or looseness relating to a complete denture that rests on them. If the flabby tissue is compressed during conventional impression making, it will later tend to recoil and dislodge the resulting overlying denture. A careful consideration and application of the principles of complete denture construction for such condition can provide a palliative form of treatment. This article describes reports of three such clinical cases, and demonstrates the use of a suitable impression technique. How to cite this article Sonune SJ, Singh S, Dange S.

Four commercially available alginate powders were selected as A: Tropicalgin, B: Cavex CA 37, C: KROMOPAN, D: United Alginate. Disinfectant solutions also were selected as I: Isopropyl alcohol 70%, II: Hydrogen peroxide- 6%, III: Povidone- Iodine- 10%. The mixing procedure was standardized by choosing a consistent manufacturer recommended powder to liquid ratio for all type of test materials. From the result obtained, it is observed that consistency suitable for impression making was obtained only with 6% hydrogen peroxide and 10 % povidone iodine for all types of alginate powders. A sandy like consistency, which is not suitable for dental impression, was obtained with isopropyl alcohol for all four types of alginates.

It is predominately seen in Indians & other Asians. The pathogenesis of the disease is thought to be multifactorial. A wide range of treatment consisting of drug management, surgical therapy & physiotherapy have been attempted till date with varying degree of benefit, but none of them have proved to be a cure for this disease. In literatures very less information is given about prosthetic treatment of patients with oral submucous fibrosis. In this case report, an edentulous patient with oral submucous fibrosis is presented & a prosthodontic rehabilitation technique that improves retention, stability, and esthetics & comfort aspect with a conservative approach is described.

Surgical and regenerative periodontal procedures can reconstruct the three-dimensional architecture of the hard- and soft-tissue defect. However, at times, these invasive procedures leave the patients with an esthetic problem. In such situations, the defects can be treated by the prosthetic approach. A predictable esthetically pleasing and functional outcome without any surgical procedure is being a choice of treatment for many. This article discusses about the treatment for the defect of excessive hard and soft tissue, using porcelain fused to a metal restoration with gingival-colored porcelain for both tooth-supported and implant-supported fixed prosthesis.
