Background: The position of the mental foramen is critical for surgery and local anesthesia. Objectives: This study was conducted to assess the position of the mental foramen and its relationship to age in a selected Iranian population. Materials and Methods: This was a cross-sectional descriptive study. Three hundred panoramic radiographs were assessed. Three variables were assessed for each r...

Increased deposition of cementum is observed in a wide number of both benign and malignant conditions. Many cases are often diagnosed during routine examination as an incidental finding. Diagnosing correctly without confusing it with other similarly appearing lesions, thus avoiding subjecting the patient to unnecessary investigations and stress, is of prime importance. We report one such case, ...

To perform successful endodontic therapy, it is important to know the anatomy and morphology of the root canal system. Peculiarities with possible anatomic variations may lead to failure due to insufficient instrumentation and inadequate three-dimensional obturation of the root canal system.[1,2] Accurate radiographic examination using different horizontal angles is crucial for the endodontist ...

Background: To evaluate different irrigation systems for removal of intracanal medicaments.Materials & Methods: A total 40 freshly extracted mandibular premolars were enrolled. The teeth longitudinally split into two halves and debris removed. then reassembled filled with Ca (OH)2 divided four groups. amount residual was calculated. results analysed using SPSS software. Results: mean remaining ...

Congenitally missing teeth is a common feature for the third molars. However, missing teeth, macrodontia and radiculomegaly occurring in a single patient is very rare. This article describes a case of agenesis of mandibular second premolars, radiculomegaly with dilacerations of a canine tooth together with elongated roots of other canines. All these features had been discerned through diagnosti...

Mandibular premolars are known to have numerous anatomic variations of their roots and root canals, which are a challenge to treat endodontically. The paper reviews literature to detail the various clinically relevant anatomic considerations with detailed techniques and methods to successfully manage these anomalies. An emphasis and detailed description of every step of treatment including preo...

AIM To describe unusual variations in the root morphology and root canal systems of mandibular first and second premolar teeth extracted for orthodontic reasons. SUMMARY Normally mandibular first and second premolar teeth have single roots with single canals. A 15-year-old patient presented for orthodontic treatment and two mandibular premolar teeth were examined post-extraction. The mandibul...

OBJECTIVE Evaluate axial mesiodistal inclinations of the mandibular molars in orthodontically treated cases, analyzing whether inclusion of second mandibular molars in treatment mechanics has any influence on final and postretention molars angulations. METHODS The sample comprised 150 panoramic radiographs of 50 patients. Patients were treated with extraction of four first premolars and divid...

Method: Bilateral mandibular premolars of 6 dogs were extracted, and after 12 weeks each dog received 8 Morse-cone connection implants immediately loaded. Four experimental groups were constituted: subcrestal with interimplant distance of 2mm and 3mm; and equicrestal with interimplant distance of 2 mm and 3 mm. After eight weeks, the animals were euthanized, the retrieved specimens were prepare...

The purpose of this article is to review the principles of case management of impacted mandibular premolars and to illustrate their potential to respond well to treatment. Although the scope of treatment may be influenced by the patient"s age, past dental history, severity of impaction, dentoalveolar development and root form, the 2 case reports demonstrate the inherent potential for good treat...
