BACKGROUND Survival and success rates of tooth transplantations even after long follow-up periods have been shown to be very high. Nevertheless, it is important to analyse factors potentially influencing these rates. The aim of this study was to assess the influence on success of potential factors. METHODS The research was based on a retrospective analysis of clinical and radiological data fr...

Purpose. To evaluate the histopathological condition of the pulp in teeth with different levels of chronic periodontitis in humans. Methods. Twenty-five single-root nondecayed teeth were divided into three groups as follows: group 1, clinical attachment level (CAL) 3 to 4 mm and alveolar bone loss (BL) from 4 to 6 mm without reaching the tooth apex; group 2, CAL ≥ 5 mm and BL > 6 mm without rea...

Introduction: Knowledge of the internal anatomy of the tooth, apical foramen (AF) and mental foramen (MF) is considered a basic prerequisite before root canal surgical and non-surgical treatments. The aim this study is evaluation the distance and situation of AF & MF to anatomic apex of mandibular  premolar. Materials & Methods: In this cross-sectional study, CBCT images of mandibular p...

Fifty-four extracted primary maxillary central incisors with some incisal edge intact as a reference point and no more than 25% of root resorption, signs of canal obstructions, or root anomalies were included. 3 The sample was equally and randomly distributed to pressure syringe, lentulo spiral, or incremental groups. Immediately following extraction, each tooth was placed in 10% formalin then ...

Intrusions occur frequently in the primary dentition. It has been reported that conservative treatment of the intruded primary tooth is preferred if the apex is away from the permanent tooth germ. Conservative treatments include waiting for spontaneous re-eruption, and surgical re-positioning and fixation. Few papers have been published in Japan comparing the prognoses of intruded primary teeth...

Tooth fusion consists of the union of crowns by the enamel and/or dentin. We describe a case of a patient who presented with a fistula in the apical portion of teeth 32 and 33. Clinically, tooth 32 showed increased crown width in relation to other teeth in the same arch. Radiographic examination evidenced fusion of tooth 32 with a possible supernumerary tooth. Cone-beam computed tomography was ...

BACKGROUND Accurate determination of the apical terminus plays a significant role in the success of root canal therapy, but accuracy may be affected by the presence of accessory canals. OBJECTIVE To evaluate the accuracy of a ratio-based electronic apex locator for roots with simulated lateral canals. METHODS Forty-two single-rooted human teeth were randomly divided into 2 groups. For each ...

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open a...
