Pathology of the Jaw: The Importance of Radiographs
Although uncommon pathology of the jaw is often referred to a specialist, dentists can contribute to an accurate diagnosis and prevent inadequate or excessive treatment by acquiring and transmitting appropriate, good-quality radiographs. Read more
Infection Control in Digital Intraoral Radiography: Evaluation of Microbiological Contamination of Photostimulable Phosphor Plates in Barrier Envelopes
Potential sources of contamination of the plates used for digital intraoral radiography were investigated. Recommendations to reduce cross-contamination include rigorous disinfection between uses and placement under aseptic conditions. Read more
Orthodontics-Related Foreign Body Causing Trismus
An orthodontic archwire penetrating the pterygoid musculature caused otalgia, pharyngitis and trismus in an otherwise healthy adolescent patient. Read more
Osseous (Cemento-osseous) Dysplasia of the Jaws: Clinical and Radiographic Analysis
Among 118 patients with osseous (cemento-osseous) dysplasia of the jaw, the condition was usually asymptomatic. Most cases presented as solitary lesions or in association with simple bone cysts or osteomyelitis. Read more
NY Times Article on CBCT in Dentistry
An article examining the use of cone-beam computed tomography (CBCT) appeared on the front page of the New York Times on November 23. Read more
Bilateral Neurogenic Masses: A Diagnostic Challenge
Recurrent mild pain in the premolar region of the mandible was traced to bilateral swellings near the mental foramina. Radiographic and laboratory investigations, accompanied by follow-up observation, were used in making the diagnosis. Read more
Dental Procedures and Stroke: A Case of Vertebral Artery Dissection
Seemingly trivial trauma caused by prolonged extension of the neck can lead to tearing of an artery. Headache, pain and vomiting following dental procedures should be investigated promptly to ensure rapid treatment of ischemia and prevent further injury. Read more
Sinus Complications with the Use of Temporary Anchorage Devices
I read with interest the article on temporary anchorage devices.1 Unfortunately, the discussion of the potential complications of treatment made no mention of thickening of the sinus membrane or possible sinus infection. Given the type of anchor used, the depth at which it is screwed and the amount of bone on the buccal aspect of the maxillary molars, one could argue that the anchor will pierce the membrane and cause sinus complications.

Developmental Disturbance of an Unerupted Permanent Incisor Due to Trauma to Its Predecessor
Intrusive injury to a primary tooth in young children often affects the underlying germ of the permanent tooth. This case study illustrates that careful and regular monitoring following treatment of such injuries can allow early detection and treatment of malformation in the permanent dentition. Read more
Is there a “safety zone” in the mandibular premolar region where damage to the mental nerve can be avoided if periapical extrusion occurs?
The mandibular premolars are located close to the mental foramina (Fig. 1). As such, various events affecting these teeth, such as odontogenic infection1 and orthodontic, endodontic, periodontal or surgical misadventure, may result in neurosensory disturbance of the mental nerves.2-4 Read more
Is routine radiography for a new patient considered overtreatment?
Radiography should never be “routine.” Like any medical test, radiography should be ordered only after clinical examination of a patient and when the history, a clinical sign or a symptom reveals a potential abnormality that cannot be investigated in any other manner. The results of the radiographic examination must be expected to influence diagnosis and treatment and, thus, the patient can be expected to receive a benefit from the exposure, which although minimal, is considered to carry some risk.

If my patient has undergone radiation treatment of the jaw, does he/she need hyperbaric oxygen therapy before I extract teeth or perform other minor oral surgery?
Osteoradionecrosis (ORN) is a feared condition recognized by all dental practitioners (Figs. 1 and 2). Some of us have witnessed this disease among our patients, and we learned in dental school how devastating it can be. The biologic effects of high-dose radiation therapy on the jaws have been well described by Marx.1,2 Although there is no threshold radiation dose beyond which ORN becomes a higher risk, it usually occurs among patients who have had radiation therapy, surgery or both for oral cancer, usually squamous cell carcinoma.
