ABSTRACT
BACKGROUND: Post preparation is an integral part of restoring endodontically treated teeth in indicated cases. Iatrogenic perforation of the root can result from preparing post space and can severely compromise the prognosis of the tooth. CASE DESCRIPTION: Two years after a patient's maxillary lateral incisor was restored with a post-retained composite resin, he went to a dental school emergency clinic with a chief complaint of soft-tissue swelling adjacent to the tooth. The authors took a periapical radiograph that revealed evidence of a circumscribed radiolucent lesion associated with the distal midroot area and a periapical radiolucency. Based on the radiograph, the authors suspected that the canal preparation for the post and the post placement had perforated the root at the base of the post. CLINICAL IMPLICATIONS: The authors used a combined surgical and orthograde approach with a biocompatible restorative material and a clear, plastic light-transmitting post to repair the iatrogenic perforation.

There are many techniques for stabilizing and splinting teeth. No matter which restorative technique is chosen, the technical elements of marginal fit, psychologic contour, cleansibility, and occlusion must be met. When the restoration is in the esthetic zone of the oral cavity, there is an additional element of achieving an acceptable cosmetic result. This article presents an overview of concepts to achieve acceptable esthetic results when teeth are joined together.

The patient, a 58-year-old woman, had started orthodontic treatment to correct spacing between the maxillary anterior teeth 6 year prior to presentation with a chief complaint of tooth discoloration and spacing. The treatment had consisted of the use of a removable appliance to retract the maxillary anterior teeth. The patient continued to wear the appliance sporadically. When she presented, the maxillary incisors were in primary occlusal trauma with Grade 2 mobility. The patient discontinued wearing the appliance. The periodontal condition was addressed with initial therapy. As part of the treatment plan to stabilize the maxillary anterior teeth and provide the patient with an esthetic result, it was decided to do a limited occlusal adjustment of the maxillary anterior teeth to control fremitus, and to place a fixed, composite resin, polyethylene ribbon-reinforced splint, using a facial approach. The esthetic restoration of these teeth was accomplished with bonded porcelain veneers.

The practice of dentistry involves viewing and evaluating small details of teeth, soft tissues, restorations, casts, and instruments. Although normal vision often is adequate to view details to make treatment decisions, the use of magnification loupes provides the clinician with an increased image size for improved visual acuity and improved posture while practicing. There are many choices when selecting a magnifying system. This article recommends the use of a binocular surgical telescope, either a flip-up type or a fixed-lens system, because it affords the clinician more choices in power of magnification, working distance, field of view, depth of field, and working angulation for improved posture.

The purpose of this study was to determine the antimicrobial activity of eight commercially available etchant materials and positive and negative controls as they came into contact with bacteria commonly found within the oral cavity. The following bacteria were used in this study: Streptococcus mutans, Streptococcus salivarius, and Actinobacillis actinomycetocomitants. The study was conducted in two parts: Part I--Etchants and controls placed within wells in agar plates; Part II--Enamel-dentin disks saturated with the etchants for 20 seconds and placed on the agar plates with the controls. Zones of microbial inhibition were measured in millimeters after 48 hours. The results of the study indicate that all of the etchants demonstrated antimicrobial activity against the bacteria tested.

The purpose of this paper is to discuss the rationale for, practice benefits of, and criteria for selecting a magnification system in dental hygiene practice. Since dental hygiene procedures require seeing the finest of detail, visual acuity is essential to providing quality patient care. Magnifying loupes are a viable solution; the physical benefits include visual assistance for presbyopic dental hygienists and enhanced musculoskeletal health for all clinicians. Clinical benefits may include improved hard- and-soft tissue evaluation, calculus and periodontal pocket detection, and radiographic interpretation without compromising infection control. Head-band or protective-glass mounted, binocular surgical loupes with flip-up capability and 2 to 2.6x magnification are recommended. Although the initial investment for them is somewhat costly, the long-term returns are enhanced quality and comfort. Dental hygienists are encouraged to use magnification systems to enhance their musculoskeletal health, improve visual acuity, and continue providing quality patient care.
