Patients' perceptions of recovery after exposure of impacted teeth with a closed-eruption technique.

This prospective study evaluated patients' perceptions of recovery after surgical exposure of impacted teeth treated with a closed-eruption surgical-orthodontic technique. Twenty-nine patients (16 female, 13 male; mean age, 16 +/- 2.8 years) were given a health-related quality of life questionnaire to be completed each postoperative day (POD) for 7 days. The questionnaire was designed to assess the patient's perception of recovery: pain, oral function, general activity, and other parameters. The impact of possible predictor variables, such as age, sex, length of surgical procedure, tooth location, height of impaction, and need for bone removal were assessed. Severe pain (27.6%, 13.8%, 3.4%) and consumption of analgesics (76%, 41%, 17%) declined gradually over the first 3 PODs. Improvement in oral function and other symptoms was evident by PODs 3 and 4. Absence from school outweighed interference in daily activity by 3 days (POD 6 vs POD 3). Buccolingual tooth location was the most significant predictor variable, with results showing a delayed recovery for patients with buccally impacted teeth. The most striking difference was reported with regard to swelling (P <.0001), followed by mouth opening (P =.008) and speech (P =.05). When the surgical procedure lasted 30 minutes or longer, there was prolonged recovery from pain (P =.01). This study provides information to patients and clinicians on postoperative recovery after surgical exposure of impacted teeth by the closed-eruption surgical-orthodontic technique.

TMJ lubrication system: its effect on the joint function, dysfunction, and treatment approach.

Normal temporomandibular joint (TMJ) movements primarily depend on free sliding of the disc down the slope of the eminence. Therefore, understanding the lubrication system and how aberrations in this system contribute to TMJ is important. Its effect on dysfunctions, such as disc displacement, anchored disc phenomenon, open lock, and osteoarthritis, are discussed in this article.

The use of lasers in dentistry: principles of operation and clinical applications.

This article describes the principles of laser operation and the clinical application of laser technology in the different fields of dentistry. It discusses the use of the Er:YAG laser in restorative dentistry, pediatric dentistry, and periodontics, as well as the introduction of a new side-firing spiral tip for efficient cleaning of the root canal system by means of lateral laser irradiation. Although the Er:YAG laser is used mostly on enamel and dentin, the gingival depigmentation procedure using this laser also is described. Clinical applications of the CO2 and diode lasers on soft tissues, particularly in the fields of oral and maxillofacial surgery and perodontics, are explained. Because teeth whitening for esthetic reasons has gained increasing popularity in dentistry, the application of diode lasers for this purpose is discussed. All the dental laser procedures described in this article are conducted at the Hebrew University-Hadassah School of Dental Medicine and are further investigated in various clinical research projects.

The implications of a broken needle in the pterygomandibular space: clinical guidelines for prevention and retrieval.

The implication of a broken anesthetic injection needle in the posterior part of the oral cavity is described. Needle breakage is preventable if proper preventive measures are used during local anesthesia administration. A broken needle should be removed immediately after a thorough localization and not left in the tissue, as previously believed. Computerized tomography (CT) scan is the proper diagnostic device to locate a broken needle. A careful surgical approach under general anesthesia is recommended to retrieve the needle. Clinical preventive guidelines are described and presented to the pediatric dentist.

Eruption of a severely displaced second permanent molar following surgical removal of an odontoma.

The process of tooth eruption is very complex, and many of its factors remain unknown. Although radiographic features can provide clues into the eruptive potential of a tooth, underlying factors that affect tooth development and eruption are not as well defined, ranging from local disturbances to systemic disease. In addition, it is difficult to predict which teeth will require treatment and when the optimal time is to intervene. The purpose of this report is to illustrate the eruption potential of an impacted molar following the removal of a developing odontoma, despite its unfavorable position in the bone, complete root development, and orthodontic attachment loss.
