ABSTRACT
Percutaneous transvenous mitral commissurotomy (PTMC) using Inoue/Accura balloon is an effective procedure for management of patients with rheumatic mitral stenosis.1 Inability to cross the mitral valve is one of the pertinent reasons for procedural failure. We describe a series of three patients who were tackled with successful PTMC using a novel technique of veno-arterial looping and in the fourth patient we used double loop entry into left ventricle with veno-arterial rail and peripheral balloon dilatation for completing the PTMC. This is first such reported case series in literature to our knowledge.

UNLABELLED: Fluorosis is one of the factors that may bring about mineralization changes in teeth. Routine treatment of root biomodification is commonly followed during Periodontal therapy. BACKGROUND: The Purpose of the present study was to compare and evaluate the morphological changes in fluorosed and nonfluorosed root dentin subsequent to the application of Tetracycline, EDTA and Citric acid. Both fluorosed and nonfluorosed teeth comprising of periodontally healthy and diseased were included in this study. METHOD: Each of them was grouped into Tetracycline Hydrochloride, EDTA and Citric acid treatment groupes. Using scanning electron microscope (SEM), the photomicrographs of dentin specimens were obtained. RESULTS: Showed that there was no significant difference in exposure of number of tubules in different groups, while significant increase in the tubular width and tubular surface area was seen in fluorosed healthy, followed by fluorosed diseased groups, nonfluorosed healthy and nonfluorosed diseased groups after root biomodification procedure using various root conditioning agents. The root biomodification procedure brings in definite difference between fluorosed and nonfluorosed dentin specimens.
ABSTRACT
Natal and Neonatal teeth although not unique anomalies, are observed in infants at birth or during the first 30 days of life. Here, the report of our four cases, in which the bilateral mandibular posterior natal teeth, which stands out to be a rare condition is presented. Etiological, clinical, histological features, complications and treatment modalities are discussed.
