Here we report the draft genomic sequences of two clinical isolates of Lactobacillus rhamnosus from infected dental pulps representing the initial stages of infection of pulp tissue. Based on 454 FLX+ pyrosequencing, the two clinical isolates infecting vital pulp had a genome length of 2.9 Mbp with distinct genomic signatures.

introduction: a desirable characteristic of root canal irrigants is the ability of dissolving soft tissues. sodium hypochlorite, an antibacterial and tissue solvent irrigant used in endodontic treatment is known to be toxic for periapical tissues. chlorhexidine gluconate, an effective antimicrobial agent, is another irrigant with limited tissue dissolving ability. a mixture of a tetracycline is...

The response of the dental pulp to calcium hydroxide or zinc oxide and eugenol cement was investigated histopathologically, using the germ-free and conventional rats. The upper first molar pulp was exposed with a p1/2 round bur through the mesial surface of the teeth and covered with the capping agents. The observation period was 1, 2, 4, 7, 10, 14 and 28 days postoperatively. The results obtai...

Fragments of spleen autotransplanted to subcutaneous tissue of the abdomen In the rat undergo almost complete necrosis and then regenerate into splenic tissue with a microscopic structure Indistinguishable from the structure of the original organ. The regenerative process reminiscent of the spleen’s embryogenesis, originates from a shell of surviving splenic tissue at the surface of the implant...

Calcium hydroxide has been extensively and steadily used for direct pulp capping in modern clinical dentistry. As it was known to have potential to induce hard tissue repair, this chemical has been applied to the exposed dental pulp and the hard tissue is expected to be regenerated above the pulp. During the reparative process of exposed pulp, primary odontoblasts that were lost as a result of ...

INTRODUCTION Recently, it has been shown that it is possible to treat an immature tooth with an infected pulp space and apical periodontitis in such a way as to heal and promote the ingrown of new vital tissue into the pulp space. However, the type of new-grown tissue is unclear. METHODS Based on the samples of a previously reported study, we further investigated histologically the types of t...

OBJECTIVE This study was carried out to determine the reliability of sex determination from teeth pulp tissue. PATIENTS AND METHODS This study was carried on 60 maxillary and mandibular premolars and permanent molars (30 male teeth and 30 female teeth) which were indicated for extraction. The teeth were categorized into three groups of 20 each (10 from males and 10 from females).Group 1-pulp ...

Yan73 is a "teinturier" red wine variety cultivated in China and used in winemaking to strengthen red wine color. Here, the anthocyanin profile in both the skin and pulp of this grape variety was analyzed by HPLC-MS. The results showed that 18 anthocyanins were detected in both the skin and the pulp, and pelargonidin-3-O-glucoside, an anthocyanin compound hardly detected in most other Vitis vin...

introduction: to investigate the ultrastructural changes of dentin irradiated with 980-nm diode laser under different parameters and to observe the morphological alterations of odontoblasts and pulp tissue to determine the safety parameters of 980-nm diode laser in the treatment of dentin hypersensitivity (dh). methods: twenty extracted human third molars were selected to prepare dentin discs. ...
