External root resorption in posttreatment orthodontic patients, if severe, may jeopardize the retention of the tooth or teeth involved. Numerous studies (1-5) have been undertaken to determine the relationship between the frequency and severity of external root resorption and orthodontic movement. Some investigators found the incidence of root resorption to be low (6-9), while others found it t...

This study investigated the impact of interaction and output modality on vocabulary learning and retention of EFL learners. To investigate the impact of Interaction, solitary (n =69) and collaborative (n =62) groups served as experimental and No Interaction No Output (n =26) as control group. To address the effect of modality, spoken (n =39) and written (n =31) modalities served as experimental...

Grammaticalization deals with a diachronic process whereby a lexical word evolves into a grammatical word. The typological study recognized the common directionality of grammaticalization among different languages. Two common directionalities in grammaticalization are recognized in the case of the modal markers of possibility: (1) ability > root possibility > permission 1 and (2) ability> root ...

AIM To examine the clinical and radiographic appearance of teeth with immature apices that were treated by single step procedure using mineral trioxide aggregate (MTA). SUMMARY Creation of a physiological hard tissue barrier with calcium hydroxide in a nonvital tooth although quite predictable has certain limitations, such as the very long duration of the treatment spread over multiple visits...

Gingival recession is defined as “Displacement of soft tissue margin apical to the cemento-enamel junction”. Gingival recessions require treatment for many reasons – impaired aesthetic appearance, root sensitivity, cervical caries or abrasion. Presence of gingival recession and gingival inflammation in areas with a lack or narrow band of attached gingiva is identified as a mucogingival problem....

Introduction: An alternative method for the treatment of non-vital deciduous teeth is Lesion Sterilization and Tissue Repair (LSTR) technique in which instead of instrumentation of the root canals and obturating them with Zinc Oxide Eugenol (ZOE), the root canals are treated with a 3-Mix paste.  Case Report: In the current case report, the therapeutic outcomes of LSTR technique are presen...

A radiographic interpretation is essential to the diagnosis of invasive cervical resorption (ICR) and the difficulty in distinguishing this lesion from internal root resorption has been highlighted in the literature. This paper reports the use of cone beam computed tomography (CBCT) in the diagnosis of ICR. The cases reports describe how CBCT can be used to make a differential diagnosis and als...

Endodontic–periodontal lesions present the challenges to the clinician as far as diagnosis, prognosis and treatment planning is concerned. One treatment modality in such cases involves separation of two roots in the furcation area with selected removal of one root. This decision is based on the extent and pattern of bone loss, root trunk and root length, ability to eliminate the osseous defect,...
