This study was performed to reveal the anatomy of the cervical canal in Angora goats. For this purpose, sixty genital tracts of adult Angora goats in estrus, weighing from 40 to 50 kg, obtained from Konya slaughterhouses, were used. The materials were examined by dissection and latex cast techniques. In dissections, the vaginal protrusions were star, duckbill, crescent, spiral, cluster and bump...

A new SWEEPS (Shock Wave Enhanced Emission Photoacoustic Streaming) modality for Er:YAG laser is presented, developed especially to improve the cleaning and disinfecting efficacy of laser-assisted endodontic procedures. Typically, shock waves are not emitted during laser-assisted irrigation of spatially confined root canals. However, by using the new SWEEPS modality, an acceleration of the coll...

The purpose of this study was to carry out a scanning electron microscopic (SEM) analysis of the cleaning qualities and smear layer removal from root canal walls, instrumented and irrigated with 2.5% NaOCl, 2.0% chlorhexidine and saline solutions. Fifty extracted teeth were used in this study. All teeth were radiographed to determine the existence of a single canal. The crowns were cut at the c...

BACKGROUND Endodontic procedures such as root canal treatment would be at the risk of failure like other medical interventions due to any unsuitable conditions. This has a causative effect in making the procedure more complicated to resulting in weak prognosis finally. Technical errors such as ledge, perforation, obstruction, broken instrument, etc. make infection control too hard or impossible...

BACKGROUND CONTEXT Acute cervical spinal cord injury (SCI) has been observed in some patients after a minor trauma to the cervical spine. The discrepancy between the severity of the trauma and the clinical symptoms has been attributed to spinal canal stenosis. However, to date, there is no universally established radiological parameter for identifying critical spinal stenosis in these patients....

Cervical pregnancy is the rarest form of ectopic pregnancy. According to different sources, its incidence varies between 1/1,000 and 1/50,000 [1]. Risk factors for the implantation in the area of the cervical canal can include structural uterine abnormalities, intrauterine adhesions, myomas, as well as a post-traumatic injury to the mucous membrane of the cervical canal. The risk accompanied by...

Irrigation has an important role during endodontic treatment. We are proposing a sequence for the different irrigating agents in order to achieve the best chemical preparation possible. During the last several years endodontics has progressed to the point for treatment to be less traumatic for the patient and less stressful for the dentist. However, if the use of nickel titanium rotary instrume...

adequate cleaning, shaping and filling of the root canal system are mandatory for successful root canal treatment. thorough knowledge of root canal morphology and unusual anatomy of the tooth is critical for the practitioner. the occurrence and location of the third mesial canal (middle mesial canal) in mandibular first and second molars in relation to other two mesial canals that were treated ...

Successes of endodontic treatment depend on cleaning and shaping of root canal and adequately obturate the prepared root canal space. 1-3 Obturation has historically been achieved with gutta percha and a sealer. The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, anastomoses between canals and a variety of fins. All this leads to...

Accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. This report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). The case report underlines the importance of complete knowledge about root canal morph...
