Objective: It has been shown that the irrigating solutions and medicament used during root canal treatment may affect the bonding strength. The aim of this study was to evaluate the effect of triple antibiotic paste (TAP), double antibiotic paste (DAP) and calcium hydroxide (CH) on the bond strength to root dentin of self-adhesive resin cement. Materials and methods: Forty-eight single-rooted h...

Pain management after root canal treatment is a very important issue in clinical practice. The purpose of this study was to evaluate the effect of occlusal reduction on postoperative pain in teeth with irreversible pulpitis and tenderness to percussion. This was a prospective, randomized study conducted in Operative Department of dental section of Bahria Dental College and Hospital from June 20...

INTRODUCTION Pain management after root canal treatment is a very important issue in clinical practice. The purpose of this study was to evaluate the effect of occlusal reduction on postoperative pain in teeth with irreversible pulpitis and tenderness to percussion. METHODS Fifty-four posterior vital teeth with sensitivity to percussion requiring endodontic treatment were included in this stu...

objectives: the purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (dec) could accelerate the amount of orthodontic tooth movement (otm) in young adult mixed breed dogs. methods: fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. orthodontic force was applied...

The aim of this study was to compare the accuracy of the Radiovisiography (RVG) with conventional Radiographic in canal length estimation in vitro for root canal treatment. Forty-single-rooted teeth were endodontically assessed and working lengths were determined using both conventional intra-oral dental film and Radiovisiography (RVG) 1R1X 70 intra-oral x-ray system. Measurement assessment was...

Inflammatory external root resorption is one of the major complications after traumatic dental injury. In this case report, we describe treatment of a maxillary central incisor affected by severe, perforating external root resorption. An 18-year-old patient presented with a previously traumatized, root-filled maxillary central incisor associated with pain and sinus tract. Radiographic examinati...

Dental trauma generally requires multidisciplinary planning and treatment for good prognosis. When immature teeth are traumatized to a degree where pulp necrosis ensues, the objective of root canal treatment should be apexogenesis and root maturation. Apexification of the root is the conventional choice, which involves cleaning the canal and filling it with a temporary medication that stimulate...

INTRODUCTION A radicular perforation caused by an inflammatory internal root resorption was present in a maxillary lateral incisor. METHODS The root canal preparation was completed with hand files and thorough irrigation. Calcium hydroxide was placed as a temporary dressing for 10 days. At the second visit, the root canal with resorption lacuna was filled with warm vertical compaction of gutt...

This article presents non-surgical resolution of an extensive periapical lesion of endodontic origin associated with the maxillary left lateral incisor. Clinical examination revealed an asymptomatic bony hard swelling confined to the palate, while radiographic analysis showed a lesion measuring 22 mm in diameter and nearly 389 mm(2) in area. Through apical patency, 4 ml of intracanal exudate wa...

removal of smear layer and disinfection of canals are important objectives of teeth root canal cleaning. in order to achieve this purpose, rinsing substances, intra canal drugs as well as ultrasound are used. today, use of laser to remove smear layer and to disinfect root canals has increasingly attracted the attentions. till now different lasers such as co2, nd:yag, er:yag, er,cr:ysgg have bee...
