Aims: To assess the effect of titanium dioxide nanoparticles (NPs) on flexural strength and cytotoxicity of heat-cured polymethyl methacrylate (PMMA) resins.
Methodology: Sixty-four rectangular and 12 circular specimens were fabricated from metal dies to test flexural strength and cytotoxicity, respectively. The rectangular specimens were grouped into four (16 specimens each)-control group (Group 1), Group 2 with 3% TiO, Group 3 with 5% TiO, and Group 4 with 7% TiO.
Background: The "All-on-four" concept for treatment of edentulous arches incorporates four implants that are placed in between mental foramina in the mandible. The prosthetic framework is an important parameter in stress/strain concentration at the implants, prosthesis, and the underlying bone. Materials such as titanium, zirconia, and carbon fibers have been used for fabrication of framework in the past.

Due to variability in the natural tooth colour, shade selection becomes an intricate procedure. The aim of this study is to determine which of the three named methods is more accurate for shade selection in aesthetic dentistry.

Patients reporting with an improper prosthesis that has a black triangle pose a challenge for soft-tissue esthetic rehabilitation. Re-restoration of such cases with conventional fixed prosthesis would be undesirable due to imbalance in pink and white esthetics.

Radiographic techniques have been found to be inadequate in providing this valuable information, unlike clinical techniques. The purpose of the present study was to determine the accuracy of various clinical techniques of ridge mapping before implant fixture placement.

Existing antifungal agents are ineffective since the Candida species become resistant and also, they become toxic. Origanum vulgare is a herbal plant with high anti-fungal activity against Candida of blood and urine origin.

Materials And Methods: Assessment of various classification systems presented for errors in artificial tooth arrangement and identifying the lacunae in each system.
Results: A comprehensive review and a classification system on the various errors that occur during the ideal arrangement of artificial teeth for complete denture prosthesis have been presented.
The Prosthetic rehabilitation of microstomia patients presents difficulties at all the stages. The difficulty starts with the preliminary impression making. This is due to the tongue rigidity and the decreased oral opening.

Microstomia has been defined as an abnormally small oral orifice associated with various etiopathologic factors. Management of these patients poses extreme difficulties in every procedure during prosthesis fabrication. Restricted mouth opening of the patient makes the insertion and the removal of the tray extremely difficult.

Shade selection procedure depends on various factors including translucency, contour and surface texture. Tooth shade selection using a conventional means involves a high degree of subjectivity. Traditional shade guides are available that use several methods for quantifying shade.

Hence, this study was carried out with the objectives of determining if these parameters are applicable to our population also.
Materials And Methods: Three hundred south Indian subjects between 18 and 26 years of age, free from facial and dental deformities were examined.
Purpose: To evaluate and compare the changes in crestal bone height around implants placed with flapless surgery and with-flap surgery.
Materials And Methods: Ten implants were placed in six patients--five using flapless and five using with-flap techniques. Single-piece root-form implants and a one-stage approach with immediate nonfunctional loading protocol were used.
