Introduction : Dental caries is one of the most prevalent chronic diseases 1. Unfortunately, there have been numerous failures with the treatment rendered, the materials used and how they are used. One significant cause for dental restoration failure is secondary caries and the need to replace the existing restoration. It has been reported that more than half of the restorations placed have been replaced because of recurrent caries. New materials and techniques have been developed to enhance adhesives in dentistry and improve the bonded interface however that interface still remains the weakest component of composite restorations. Marginal degradation and the …

This study evaluated whether depression with or without the use of antidepressant was associated with changes in inflammatory markers, intraorally and systemically, GCF volume, serum biomarker levels. Cross-sectional data were collected from individuals with moderate periodontitis who were assigned to one of three groups based upon their medical history, medication usage, and answers to a validated survey instrument that assessed their level of clinical depression. Three groups of patients were compared: 1) patients with clinically diagnosed depression taking antidepressant medications [selective serotonin reuptake inhibitors (SSRIs), norepinephrine-dopamine reuptake inhibitor (NDRIs), or serotonin and norepinephrine reuptake inhibitors (SNRIs)]. 2) patients with clinically …

Mesenchymal stem cells have been very attractive treatment modality in regenerative medicine, but not so much in regenerative dentistry. This can be attributed to the difficulty in obtaining dental origin stem cells without extracting a tooth or other invasive procedures. Autogenous gingival graft harvested from palatal tissue is used as the gold standard for treating single tooth recession. The healing of the gingival graft has been shown to be mostly depended on the recipient side more than the graft itself. This study is aiming to find if the palatal tissue has cells with mesenchymal characteristics that are helping in the …

ABSTRACT Introduction: Zirconia is classified by the mole percentage of yttria contained in the zirconia. The most strong and opaque material contains 3 mol % yttria, intermediate strength and opacity contain 4 mol %, and whereas 5 mol % is the weakest but most translucent zirconia. Refined zirconia powder is pressed into a mold to form a disc which is then milled to form a restoration. Post milling of sintered zirconia restorations is necessary to obtain final mechanical and physical properties of the restoration. Traditionally conventional sintering cycles required 6-8 hours to sinter. Whereas, fast sintering cycles have been have …
