Ultrastructural Changes of Synapses in the Hippocampus of Sprague Dawley Rat Brain following Exposure to Naphthalene Balls.

Introduction: The synaptic contacts play an important role in central nervous system (CNS) functioning. Ultrastructural features of synapses in CNS are not studied in naphthalene neurotoxicity model.

Materials And Methodology: In the present work, transmission electron microscopy was used for studying the ultrastructural features of synapses in the hippocampus of Sprague Dawley rat brain, on subsequent exposure to naphthalene balls.

To Restrain or Refrain: Determination of Parental Attitude towards the Child's Experience with Protective Stabilization.

Background: To overcome disruptive behavior of children, pediatric dentists rely on various behavior management techniques. When dental therapy is pertinent and nonaversive techniques like tell-show-do, voice control, and positive reinforcement are ineffective; the role of advanced behavior guidance techniques like physical restraints and protective stabilization is of paramount importance.

Aim: The study was carried out to elicit parents' opinion and record their response to their children's experience who underwent dental treatment with an extra assistant for protective stabilization.

Nicotina Stomatitis - A Report of Two Cases.

Nicotina stomatitis is the inflammation of the minor salivary glands present in the hard palate due to chronic smoking habit. The patients are mostly symptomless and present with multiple red discrete papules in the hard palate surrounded by grayish white areas. The histopathology of the lesion is discussed and cessation of the smoking habit treats the condition within 2-4 weeks.

Survival Function of Clinical and Radiographic Success of Three Obturating Materials in Primary Teeth at 3, 6 and 9 Months Periodic Intervals - A Randomized Controlled Clinical Trial.

The study aims to assess clinically and radiographically the success of zinc oxide eugenol, metapex, and endoflas as root canal obturating materials in primary teeth over 3, 6, and 9 months of time intervals. The randomized controlled trial was performed in 60 primary molars of 36 children aged between 4 and 9 years. Permanent restorations were given and stainless steel crowns were placed for the treated tooth.
