Long-term outcome assessment of closed treatment of mandibular fractures.

Mandibular fractures are among the most common trauma injuries of the craniomaxillofacial region. This study evaluated the late results of mandibles fractures treated with arch bar. Forty-nine patients were examined clinically and by questionnaires for late results of arch bar treatment.

Rapid endodontic management of type II dens invaginatus using an MTA plug: a case report.

Dens invaginatus is an anomaly characterized by an infolding of enamel and dentin that can lead to caries and pulpal death while the tooth is still immature, and present difficulties with diagnosis and treatment. Generally such open apices are managed by long term apexifaction procedures. This article demonstrated rapid management of a maxillary lateral incisor having a type 2 dens invaginatus, necrotic pulp, open apex and very large periradicular lesion using calcium hydroxide for one week prior to placement of a mineral trioxide aggregate (MTA) plug.

Calcium-enriched mixture cement as artificial apical barrier: A case series.

In comparison to the conventional apexification using calcium hydroxide, artificial apical barrier technique is more valuable and less time consuming. This article describes successful use of calcium-enriched mixture (CEM) cement as an artificial apical barrier in open apices. In this study, 13 single-rooted teeth with necrotic pulps and open apices were treated non-surgically.

Comparative stress distribution of implant-retained mandibular ball-supported and bar-supported overlay dentures: a finite element analysis.

Implant-retained mandibular ball-supported and bar-supported overlay dentures are the two most common treatment options for the edentulous mandible. The superior option in terms of strain distribution should be determined. The three-dimensional model of mandible (based on computerized tomography scan) and its overlying implant-retained bar-supported and ball-supported overlay dentures were simulated using SolidWorks, NURBS, and ANSYS Workbench.

Effects of Qigong exercises on 3 different parameters of human saliva.

Objective: To analyze the effects of a Qigong program on various parameters of unstimulated saliva, including volume, pH and secretory immunoglobulin A (S-IgA) level.

Methods: Twice a day from the beginning of Fall 2005, twenty-three healthy volunteers aged 22-24 did special Qigong exercises and massage of acupuncture points which stimulated the energy cycle and increased body water energy. The unstimulated saliva volume and pH were recorded every week in Spring (April, May, June) 2005 before the volunteers started to learn and exercise Qigong, and after Qigong intervention in Spring (April, May, June) 2006.

Periodontal health in mothers of preterm and term infants.

Objective: Recent studies have suggested that chronic periodontitis may induce an inflammatory response which can cause premature delivery. This study was designed to assess the association between periodontal health and preterm labor in Iranian female population.

Materials And Methods: In this case-control study, 201 pregnant women without systemic disease or other risk factors for preterm labor were chosen.
