Many endodontically treated teeth require a post to improve the retention of the coronal restoration, which necessitates removal of the coronal part of the gutta-percha from the canal by thermal method, among other techniques. However, this technique carries the risk of heat conduction to the
OBJECTIVE
There are no data comparing coronal leakage of teeth prepared to different apical sizes and obturated with gutta-percha and sealer. The aim of this study was to investigate the effect of apical preparation size on the leakage of obturated root canals. Large apical openings are encountered
For many years, gutta-percha has been the root canal filling material of choice. Chloroform is one of the most efficient solvents widely used for gutta-percha removal in retreatment cases, despite being toxic and carcinogenic. The present case report discusses a chloroform extrusion through an
OBJECTIVE
This prospective study evaluated the frequency and intensity of postobturation pain and associated factors in adolescents undergoing one- and two-visit root canal treatment.
METHODS
121 patients aged 11-18 years presenting with molars with pulp necrosis were assigned randomly into two
The aim of this study was to evaluate the incidence of postoperative pain and the type of periapical repair, after one-appointment endodontic treatment in asymptomatic patients who presented with pulpal necrosis and radiographically visible chronic periapical lesions. For that, after biomechanical
Calcium hydroxide is currently used in dentistry for endodontic treatments where its main advantage is its antibacterial and anti-inflammatory activity. However, it also has some drawbacks such as pulp necrosis, slight solubility, slow and insufficient hardening, and retraction on drying. In
Although numerous studies have been conducted on apexification using mineral trioxide aggregate (MTA), direct observation of extracted human teeth after the procedure has been rarely reported. This case report describes a mandibular premolar treated 2.5 years ago and extracted recently for
The present report presents a case of dens invaginatus (DI) in a patient with 4 maxillary incisors. A 24-year-old female complained of swelling of the maxillary left anterior region and discoloration of the maxillary left anterior tooth. The maxillary left lateral incisor (tooth #22) showed pulp
Many of the proinflammatory effects of interleukin (IL)-1beta and tumor necrosis factor-alpha (TNF-alpha) are mediated through cyclooxygenase-2 (COX-2)-dependent prostaglandin E2 (PGE2). The purpose of this study was to examine the expression of IL-1beta and TNF-alpha in COX-2-deficient osteoblasts
BACKGROUND
Orthodontic forces produce a series of changes in dental pulp. However, no one has attempted to investigate the incidence of pulp necrosis after orthodontic therapy in the clinic. In this study, we aimed to investigate pulp vitality and histologic changes after the application of moderate
Dens invaginatus is one of the most common anomalies of tooth structure. It is caused by the invagination of the crown surface during odontogenesis that enters the pulp chamber of the affected tooth. Depending on the complexity of invagination, the tooth might present with pulp necrosis, open apex
Dens invaginatus is a developmental anomaly, caused by deepening of the enamel organ into the dental papilla before calcification of the dental tissues. Teeth with dens invagination are susceptible to early caries and pulp necrosis within a few years of eruption or even before root end closure. This
This paper describes and discusses the multidisciplinary treatment involving a permanent maxillary lateral incisor fused to a supernumerary tooth, both presenting pulp necrosis and periapical lesion. A 15-year-old male patient sought treatment complaining of pain, swelling and mobility on the
OBJECTIVE
To report the induction of apical root development by calcium hydroxide in teeth with pulp necrosis and periapical radiolucency.
CONCLUSIONS
A 10-year-old male patient was admitted to the clinic complaining of an intense pain and oedema on the anterior facial region, compatible with an
The method of immediate root canal filling following vital pulp extirpation involves many problems to be solved clinically. Therefore, the present study was performed to increase the clinical usefulness by applying formalin medicine in the root canal before immediate root canal filling after vital
