Current update on portable dental equipment.

The dental care needs of the elderly are increasing as their population grows. For some of the elderly (eg, the nonambulatory, homebound, institutionalized), accessing dental care is a problem because they are unable to visit a traditional dental clinic. In the past, dental care has been taken to the homebound or institutionalized elderly by dentists using portable dental equipment. However, the perception that such equipment is difficult or impossible to obtain has limited the availability of on-site care. The purpose of this article is to describe various types of portable dental equipment and their features so that dentists interested in providing care to this group of patients are aware of them.

Physical self-regulation training for the management of temporomandibular disorders.

AIMS: To evaluate the long-term effectiveness of a brief skills training program for the management of chronic facial muscle pain. This program of physical self-regulation (PSR) involved primarily training in breathing, postural relaxation, and proprioceptive re-education. METHODS: Physical self-regulation training was presented by a dentist during two 50-minute sessions spaced at 3-week intervals and was compared to a standard dental care (SDC) program that included a flat-plane intraoral appliance and self-care instructions provided by a dentist. Participants (n = 44) were initially evaluated by a dentist experienced in the diagnosis and management of orofacial pain and were determined to have myofascial pain (Type 1a and 1b diagnoses per the Research Diagnostic Criteria) prior to random assignment to either the PSR or SDC conditions. Posttreatment evaluations 6 weeks and 26 weeks after treatment had begun were conducted by a dentist who was not aware of which treatment the participants received. RESULTS: Initial results indicated that pain severity and life interference from pain were reduced in both groups (P < 0.001), while perception of control was increased (P < 0.001), as was incisal opening without pain (P < 0.05). At the 26-week follow-up, the PSR group reported less pain (P < 0.04) and greater incisal opening, both with (P < 0.04) and without (P < 0.01) pain, than the SDC group. There were also significant decreases (P < 0.05) in affective distress, somatization, obsessive-compulsive symptoms, tender point sensitivity, awareness of tooth contact, and sleep dysfunction for both groups over time. CONCLUSION: The findings support the use of PSR for the short- and long-term management of muscle pain in the facial region. These results are discussed in terms of the potential mechanisms by which self-regulation treatment strategies are effective for the management of these pain disorders.

Effects of sonic instrumentation on the apical preparation of curved canals.

This study compared apical transportation produced in curved (45- to 60-degree) molar canals instrumented with two MM-3000 Sonic Air test files (Rispi-Sonic and Trio-Sonic) with apical transportation from instrumentation with conventional K-type files. Seventy-five extracted human permanent mandibular molars were equally divided into three groups. Results showed that 92 (61%) of 150 measurements demonstrated no transportation, and only 7 (5%) had transportation between 0.25 and 0.5 mm. Most of the transportation was 0.25 mm or less, and no file produced transportation greater than 0.5 mm in a buccolingual or mesiodistal direction. Statistical analysis (chi-square test and analysis of variance) showed no significant difference (p greater than 0.05) in the amount of apical transportation in canals prepared with the Kerr K-type, Rispi-Sonic, or Trio-Sonic files.
