Introduction: An alternative method for the treatment of non-vital deciduous teeth is Lesion Sterilization and Tissue Repair (LSTR) technique in which instead of instrumentation of the root canals and obturating them with Zinc Oxide Eugenol (ZOE), the root canals are treated with a 3-Mix paste.  Case Report: In the current case report, the therapeutic outcomes of LSTR technique are presen...

Objective To evaluate the degree of postoperative pain in patients with necrotic teeth symptomatic apical periodontitis after applying ultrasonic irrigation or manual dynamic agitation.
 Methods Seventy-eight diagnosed mandibular first molar were randomly allocated into 1 3 separate groups (n=26); Manual Dynamic Agitation group, Ultra X NaviTip group (control). After a single-visit root ca...

the term riga-fede disease has been used to describe chronic traumatic ulceration that occurs on the ventral surface of the tongue by natal and neonatal teeth in infants. it is important to diagnose the lesion and treat it by eliminating the source of trauma. in this case report, the neonatal tooth was extracted and after 2 weeks the lesion was resolved and the baby was feeding well.in addition...

Two fused cyclopentadithiophenebis(dicyanovinylene) derivatives (FCPDT-16 and FCPDT-C24) with a low-lying LUMO energy level (3.88 eV) and a rigid core structurewere successfully synthesized.They have good thermal stability and form highly ordered packing structures both in the bulk solid state and in thin films. The field effect transistors fabricated from a solution of these two compounds show...

A pyrene-fused phenazinothiadiazole that shows electron mobilities (μe = 0.016 cm(2) V(-1) s(-1)) two orders of magnitude higher than those reported for pyrene-fused pyrazaacenes is described.

Dental pulp is a soft connective tissue that surrounded by highly mineralized tissues such as enamel, dentin, cementum and provides homeostasis of the tooth. Pulp specialized with limited regeneration ability due to anatomical arrangement postmitotic structure odontoblastic cells. Classical endodontic treatment based on removing infected root dentin filling disinfected canal cavity bioinert mat...

This report describes an outbreak of purulent mandibular and/or maxillary osteomyelitis caused by Pseudomonas aeruginosa in a sheep flock located in the Khuzestan province, Iran. Jaw bones of almost 100 out of 500 mature sheep in a flock became severely deformed with a variably sized firm swelling, without any signs of inflammation in the surrounding soft tissues. The affected animals showed an...
