Your abbreviated orthodontic therapy for Ms Bell is about to conclude. The referring dentist requested that you upright the mandibular left second molar a few more degrees before implant replacement of the absent first molar. The gable bends you placed at last month's appointment induced occlusal trauma with the maxillary arch, so you begin to reduce the relatively new ceramic crown on the mandibular second molar. Suddenly, you notice that you've perforated the second molar crown. Ms Bell has no idea of the problem as she continues to listen to the music from her iPod. You wish you had mentioned this possibility before you...

We appreciate Dr Cao's interest in our article (Wei YJ, Lin YC, Kuang SH, Yang SF, Lee SY, Lai YL. Esthetic periodontal surgery for impacted dilacerated maxillary central incisors. Am J Orthod Dentofacial Orthop 2012;142:546-51). Dr Cao questioned the longevity of a maxillary central incisor in patient 1 after root-end resection. We believe that it is essential to make an effort to save a maxillary anterior tooth for a growing child to achieve esthetics, phonation, and function. More importantly, tooth extrusion instead of tooth extraction facilitates bone growth in the premaxilla; this shall benefit the patient if further...

Treatment of impacted dilacerated maxillary central incisors
We read the article by Dr Wei et al (Wei YJ, Lin YC, Kuang SH, Yang SF, Lee SY, Lai YL. Esthetic periodontal surgery for impacted dilacerated maxillary central incisors. Am J Orthod Dentofacial Orthop 2012;142:546-51) about the treatment of impacted dilacerated maxillary central incisors with great interest. The authors showed that soft-tissue management with periodontal surgical strategies can achieve desirable esthetic results of inverted dilacerated crowns. As we know, the length of the tooth root is associated with the eventual service and life of the tooth. Although the esthetic results are satisfactory, the root of ...

Buccal bone regeneration
The article, “Severe complication of a bonded mandibular lingual retainer,” in the September issue (Pazera P, Fudalej P, Katsaros C. Am J Orthod Dentofacial Orthop 2012;142:406-9) was interesting. The authors carefully documented a complication with a broken lingual flexible spiral wire retainer. Four years after treatment, the root of a canine had moved out of the buccal cortical bone. Cone-beam computed tomography sections of the canine before and after retreatment beautifully demonstrated partial recovery of the labial cortical plate. The authors concluded that buccal bone regeneration and recoverage of parts of a r...

We appreciate Dr Karthickeyan's interest in our article, and we want to clarify some of his concerns with the methodology and conclusions. Although other factors might play roles in the etiology of anterior open bite at an early age, thumb- and dummy-sucking are the primary etiologic agents of anterior open bite at this stage. Anterior tongue thrusting and anterior tongue-rest posture are always present, in varying degrees, with an anterior open bite. A vertical growth pattern is associated with an anterior open bite. Tongue spurs are effective in eliminating the deleterious sucking habits, tongue thrusting, and anterior ...

Do you have an evidence-based practice?
The term “evidence-based” receives considerable usage by both academicians and clinicians in today’s professional dental environment. In some cases it is appropriately used, but often it is inappropriately applied. According to David Sackett, a pioneer of evidence-based decision making, “evidence-based practice” is the conscientious, explicit, and judicious use of current best evidence when making decisions about the care of a patient. Evidence-based practice means integrating individual clinical expertise with the best-available clinical research: ie, systematic reviews and randomized controlled trials. So how d...

Osteonecrosis associated with dental implants in patients undergoing bisphosphonate treatment
ConclusionThese results and those of others suggested that already osseointegrated dental implants can also cause the osteonecrosis around the implant after BP administration. En block sequestration of bone with implant might be one of the characteristics of implant‐related BRONJ, which is different from peri‐implantitis‐induced bone destruction. The possible role of microcracks in this type of bone destruction needs to be examined further.

SEM and Stereomicroscopic Analysis of Cut Marks in Fresh and Burned Bone.
This study documents the prevalence of cut mark characteristics in fresh and burned domestic pig ribs. Stab wounds from single edge serrated and smooth-edged knives were inflicted in the vertebral and sternal regions of each fresh rib. Each rack of ribs was then divided into vertebral and sternal units. Vertebral units were defleshed and their associated cut marks were examined using a stereomicroscope. Sternal units were burned in an outdoor fire pit and examined with the addition of a scanning electron microscope (SEM). Linear cuts, V-shaped cross-sections, mounding, hinge fractures, and wastage were all observed on burn...

Precise technique for simple and accurate pip arthrodesis using a blunt KW technique
Abstract: Proximal interphalangeal joint (PIP) arthrodesis is a very common procedure in the practice of foot and ankle surgeons. The standard technique recommends using a Kirschner wire (KW) with double sharp ends. Using this technique there are some complication that can be eliminated by small modification. The technique of proximal interphalangeal joint arthrodesis using a simple blunt KW on one side with an accurate placement and avoidance of metatarsophalangeal joint (MTPJ) penetration without the need for fluoroscopy is described. This technique is simple, reproducible, very economical and avoiding most of the compli...

Practical experience of telehealth between an Antarctic station and Japan
The Japanese Antarctic Research Expedition (JARE) has had a presence in Antarctica since 1956. The Syowa station is 15,000 km from Japan and evacuation of patients is impossible during the winter months. From 1956 to 2003, a total of 4932 telemedical consultations were undertaken, i.e. every member of the station needed an average of 4 medical consultations each winter. Forty five percent of the consultations were surgical or orthopaedic cases, 23% were for internal medicine and 12% were for dental problems. In the early 1980s, satellite radio-telephony was found to be useful for consultations, but did not have the ability...

An analysis of an ongoing trial of rural videoconference fracture clinics
Since January 2011, videoconference fracture clinics have been held between the rural Mt Isa Hospital (MIH) and the tertiary referral centre, the Princess Alexandra Hospital in Brisbane, approximately 900 km away. We have examined the activity and costs of the videoconferencing clinics over a 17-month period. During the study period, 27 clinics were held and 21 patient transfers (four of whom were children) were saved. The cost of a transfer was estimated to be $1269 for an adult and $2134 for a child with an accompanying adult. The cost of holding a videoconference fracture clinic was estimated to be $1285 per clinic. Dur...

Identification and management of osteoporosis in older adults
Abstract: Fractures resulting from osteoporosis are a major public health problem. Physicians should be aware of the major risk factors for osteoporosis and refer appropriately for bone densitometry. Risk factors include prior fracture, a family history of fracture, slender habitus, early menopause, treatment with drugs known to affect bone (glucocorticoids) and diseases known to affect bone (rheumatoid arthritis). The diagnosis of osteoporosis can be made if the bone density T-score is −2.5 or below. This information can be used with other risk factors to estimate the 10-year risk of fractures. Patients at the highest r...

Commentary: A Good Question
These are remarkable data. It is not easy to obtain magnetic resonance images (MRIs) of 300 wrists prospectively in patients who present to an emergency department with radial-sided wrist pain after injury. It is essentially impossible in the United States. To be able to add a computed tomography (CT) scan for a subset of patients with scaphoid fractures is even more impressive. My disappointment with the study is that it does not address the most meaningful clinical dilemmas, and it therefore requires careful interpretation.

Measurement Characteristics and Clinical Utility of the Berg Balance Scale Among Individuals With Stroke
Balance impairments that result from stroke have been associated with fall risk and limited independence in activities of daily living and walking ability. Approximately 50% to 70% of individuals fall within the first year after having a stroke, which frequently results in a hip fracture. Because balance has a substantial impact on function for individuals poststroke, it is frequently assessed and treated during stroke rehabilitation. The Berg Balance Scale (BBS) is one of the most commonly used instruments to assess balance deficits during stroke rehabilitation; it assists in identifying individuals who are at risk for fa...

In Vivo Kinematics of the Scaphoid, Lunate, Capitate, and Third Metacarpal in Extreme Wrist Flexion and Extension
Conclusions: The contributions of the scaphoid and lunate to capitate rotation were approximately 25% less in extreme extension compared with wrist motion through an active range of motion. More than half the motion of the carpus when the wrist was loaded in extension occurred at the midcarpal joint. Clinical relevance: These findings highlight the difference in kinematics of the carpus at the extremes of wrist motion, which occur during activities and injuries, and give insight into the possible etiologies of the scaphoid fractures, interosseous ligament injuries, and carpometacarpal bossing.

European registers for total ankle replacement
Registers for hip and knee replacements have been used for nearly 30 years, starting in Sweden 1975 with the knee arthroplasty register. Many other countries have followed this trend, and the results from the registers give valuable information about survival rates for different devices, detailed information of which patients groups that are at risk of failure, regarding the best technique (for example whether prostheses should be fixed with or without bone cement), and can even differentiate outcomes between centers and surgeons. The value of registries depends on compliance, as many are voluntary, although the UK Departm...

Bone Marrow Mesenchymal Stem Cells: Fat On and Blast Off by FGF21.
Abstract Bone marrow mesenchymal stem cells (BMMSCs) are multipotent marrow stromal cells with the ability to differentiate into a variety of cell types required for tissue regeneration including osteoblasts and chondrocytes. Thus, they hold tremendous potential as powerful therapeutic strategies for the prevention and treatment of degenerative disorders including osteoporosis and osteoarthritis. The differentiation of BMMSCs into competing lineages such as osteoblasts and marrow adipocytes is regulated by various environmental cues and intrinsic signaling pathways. Here I highlight recent advances in the understan...

Intermittent Administration of Human Parathyroid Hormone before Osteosynthesis Stimulates Cancellous Bone Union in Ovariectomized Rats.
Abstract It has been reported that intermittent administration of human parathyroid hormone (h-PTH) promotes bone healing after surgery for osteoporotic fractures. If bone healing is promoted by the administration of h-PTH during pre-operative waiting period, we can prevent prolonged bed rest. Therefore, we evaluated the effects of pre-operative h-PTH treatment on cancellous bone union and its mechanism for fracture healing in ovariectomized rats as a model for osteoporosis. Ovariectomized 7-month-old female Sprague-Dawley rats underwent an osteotomy of the proximal tibia as a fracture model, and h-PTH (30 μg/kg b...

Abstract With specialist knowledge ophthalmologists can make a valuable contribution to the interdisciplinary work-up of patients with vertigo as the leading symptom. The neuro-ophthalmological examination of eye movements by an ophthalmologist and/or orthoptist is an important contribution because the various vertigo syndromes can only be correctly evaluated by a combined examination of the vestibular and ocular motor systems.
