The course of pain intensity and frequency of adolescents treated because of temporomandibular disorders: A long-term follow-up. Clin Exp Dent Res 2020; 6:407-414. [PMID: 32304185 PMCID: PMC7453768 DOI: 10.1002/cre2.289] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 01/31/2020] [Accepted: 03/06/2020] [Indexed: 11/07/2022] Open
Abstract
OBJECTIVES To evaluate the course of pain intensity and frequency related to temporomandibular disorders (TMDs) 15 years (range 5-21 years) after having received TMD treatment as adolescents due to frequent (at least once a week) TMD pain in two controlled trials. MATERIALS AND METHODS In the first trial, subjects (n = 122) were randomly allocated to either information only, received in a control condition (Co), or information and an occlusal appliance (OA) versus relaxation therapy (RT). In the second trial, including 64 subjects, nonresponders to OA or RT were subsequently allocated to the alternate treatment (ST). All study participants having completed the trials (n = 167) were invited to a long-term follow-up evaluations, with a response rate of 69.5% (n = 116). Patient-reported outcomes of TMD-related frequency and intensity were appraised relative to baseline data and short-term outcomes as observed in the two trials by use of general linear mixed model and generalized estimation equation statistics. RESULTS A significantly higher proportion of participants treated with OA and in the combined RT/Co condition than those in the ST group, reported a frequency level of TMD pain less than once week at post-treatment and the long-term follow-up. Adolescents treated with OA showed significantly lower TMD pain intensity levels post-treatment than those in the other two treatment conditions. While no difference between the OA and the RT/Co conditions was found in the long-term follow-up, participants in these two conditions were significantly more improved than those in the ST group. CONCLUSION Adolescents treated with an OA clearly showed better outcome with regard to intensity and frequency in a long-term follow-up of TMD pain than those treated with RT and ST for nonresponders. These latter individuals need special clinical attention and more effective supplementary treatment methods to be developed.

Long-Term Objective Adherence to Mandibular Advancement Device Therapy Versus Continuous Positive Airway Pressure in Patients With Moderate Obstructive Sleep Apnea. J Clin Sleep Med 2019; 15:1655-1663. [PMID: 31739856 PMCID: PMC6853388 DOI: 10.5664/jcsm.8034] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 07/17/2019] [Accepted: 07/17/2019] [Indexed: 02/07/2023]
Abstract
STUDY OBJECTIVES Comparable health effects of mandibular advancement device (MAD) and continuous positive airway pressure (CPAP) therapy have been attributed to higher adherence with MAD compared with CPAP therapy. The objective of this study was to make a direct comparison of the objective adherence between MAD and CPAP in patients with moderate obstructive sleep apnea (OSA). METHODS Adherence was monitored for 12 months in 59 patients with moderate OSA (apnea-hypopnea index 15-30 events/h) as part of a randomized controlled trial. Objective adherence with MAD was assessed using the TheraMon microsensor. Objective adherence with CPAP was assessed using the built-in registration software with readout on SD card. Self-reported adherence with both therapies was assessed using a questionnaire. RESULTS Forty patients (68%) completed the study with the therapy to which they were randomly assigned. Median (interquartile range) objective adherence (h/night) in the 3rd month was 7.4 (5.2-8.2) for MAD and 6.8 (5.7-7.6) for CPAP (P = .41), compared to 6.9 (3.5-7.9) with MAD and 6.8 (5.2-7.6) with CPAP (P = .85) in the 12th month. There were no significant changes between the 3rd and 12th month for both MAD (P = .21) and CPAP (P = .46). Changes in adherence were not significantly different between MAD and CPAP (P = .51). Self-reported adherence was significantly higher with MAD than CPAP at all follow-ups. Self-reported adherence with CPAP was lower than objective CPAP adherence at the 6th and 12th month (P = .02). CONCLUSIONS Objective adherence with MAD and CPAP is comparable and consistent over time. Self-reported adherence is higher with MAD than with CPAP giving rise to interesting discrepancy between objective and self-reported adherence with CPAP.

Abstract
A treatment regime combining acupuncture, occlusal splint and point injection therapy for temporomandibular disorders (TMD) is presented. There were 89 consecutive patients treated by the regime in this case series but four patients dropped out after two to three visits. Data and treatment results of the remaining 85 patients who had treatment completed were analysed. It was found that 73 (85%) of patients with TMD had symptoms relieved within six visits under this regime. Complications were rare and minor. Acupuncture treatment, in combination with splint therapy and point injection therapy, appears to be effective for managing TMD. However, further research, using randomised controlled trials should be conducted to ascertain its effectiveness over other treatment modalities.

Abstract
Context • Patients with fibromyalgia syndrome (FMS) report frequent and severe symptoms from temporomandibular disorders (TMDs). The appropriate treatment of TMDs remains controversial. No studies have occurred on the efficacy of therapy with a laser or an occlusal stabilization splint in the treatment of TMDs in patients with FMS. Objective • The study intended to investigate the therapeutic effects of laser therapy and of an occlusal stabilization splint for reducing pain and dysfunction and improving the quality of sleep in patients with TMDs and FMS. Design • The research team designed a single-blinded, randomized clinical trial. Setting • The study took place in the research laboratory at the University of Granada (Granada, Spain). Participants • Participants were 58 women and men who had been diagnosed with FMS and TMDs and who were referred from the clinical setting. Intervention • Participants were randomly assigned to the occlusal-splint or the laser group. The laser group received a treatment protocol in which laser therapy was applied to the participant's tender points, and the occlusal-splint group underwent a treatment protocol in which an occlusal stabilization splint was used. Both groups underwent treatment for 12 wk. Outcomes Measures • Pain intensity, widespread pain, quality of sleep, severity of symptoms, active and passive mouth opening, and joint sounds were assessed in both groups at baseline and after the last intervention. The measurements used were (1) a visual analogue scale (VAS), (2) the Widespread Pain Index (WPI), (3) the Symptom Severity Scale (SSS), (4) the Patient's Global Impression of Change (PGIC), (5) the Pittsburgh Quality of Sleep Questionnaire Index (PSQI), (6) an assessment of the number of tender points, (7) a measurement of the active mouth opening, (8) a measurement of the vertical overlap of the incisors, and (9) the measurement of joint sounds during mouth opening and closing. Results • The group X time interaction for the 2 × 2 mixed analysis of variance found no statistically significant differences between the 2 treatment groups: (1) VAS, P = .591; (2) WPI, P = .112; (3) SSS, P = .227; (4) PGIC, P = .329; (5) number of tender points, P = .107; (6) right and left clicking sounds in the jaw joint during palpation at mouth opening, P = .723 and P = .121, respectively; and (7) right and left clicking sounds in the jaw joint during palpation at mouth closing, P = .743 and P = .698, respectively. Compared with baseline, the laser treatment showed significant improvements on several outcomes, including the VAS, P < .001; WPI, P = .003; and SSS, P = .001. Overall, the study found an average improvement in symptoms from baseline of 21% , P < .001, based on the PGIC. Conclusions • Laser therapy or an occlusal stabilization splint can be an alternative therapeutic treatment for reducing pain symptoms and the clicking sound for TMDs in patients with FMS.

Abstract
OBJECTIVE The aim of this study was to analyze dentist's clinical decision-making related to treatment need for temporomandibular disorders (TMD) in an adult population. MATERIALS AND METHODS The study population comprised 779 randomly selected 35, 50, 65 and 75 year old individuals living in the county of Västerbotten, Sweden. The participants filled out a questionnaire and were examined clinically according to a structured protocol. The four examiners (two men, two women) were experienced dentists and were calibrated before the start of the study. After examination they individually assessed the need of treatment owing to TMD. RESULTS In total, 15% of the study population was considered to have a treatment need owing to TMD. The highest estimate was noted for 35 and 50 years old women and the lowest for 65 and 75 years old men. Overall, 21% of the women and 8% of the men were considered to have a treatment need owing to TMD, with statistically significant differences between men and women for the 35 and 50 years old groups. Inter-individual variations in dentists' decisions were observed. In a multivariate analysis, female gender, signs and symptoms of TMD pain, signs and symptoms of TMD dysfunction and smoking were associated with estimated treatment need. CONCLUSIONS The prevalence of estimated treatment need owing to TMD was fairly high, but the dentists' clinical decision-making process showed large inter-individual variability. The observation calls for further research on the factors affecting the decision-making process in care providers.

Abstract
Stabilization splint is the treatment of choice for pain control in temporomandibular disorder (TMD) patients, even though its mechanism of action is still unknown. The aim of this systematic review is to provide a critical overview of the effectiveness of stabilization splint therapy on the basis of currently available literature data. The available Medline database was searched and 24 studies published since the 1995s have been consequently included in this review. The selection criteria were randomized controlled trials and clinical trials comparing splint therapy to either no treatment or another active treatment (physiotherapy, relaxation and drugs). Studies were grouped according to treatment type. Based on the currently best evidence available, it appears that stabilization splint has similar efficacy in controlling TMD symptoms as other active treatments (physiotherapy, relaxation and drugs). Stabilization splint therapy may be beneficial in reducing pain at rest and on palpation when compared with non-occluding splint. During a short period, education was slightly more effective than occlusal splint in treating spontaneous muscle pain. These two treatments did not have significantly different effects on pain-free mouth opening and pain during chewing. This review has shown evidence that most TMD patients are helped by incorporation of a stabilization splint. There is not enough data on the long-term efficacy and effectiveness of this widely used therapeutic tool. In the future, there is a need for well-conducted randomized controlled trials paying attention to adequate sample size, blind outcome assessment, duration of follow up, and using standardized methods for measuring treatment outcomes.

Abstract
BACKGROUND The authors conducted a survey to characterize the strategies used by general dentists to manage pain related to temporomandibular muscle and joint disorders (TMJDs) and to assess the feasibility of conducting a randomized controlled trial (RCT) to determine the effectiveness of these strategies. METHODS Dentists from three dental practice-based research networks (PBRNs) (The Dental Practice-Based Research Network, Practitioners Engaged in Applied Research and Learning Network and Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry) agreed to participate in this survey. RESULTS Of 862 dentists surveyed, 654 were general dentists who treated TMJDs; among these, 80.3 percent stated they would participate in a future RCT. Dentists treated an average of three patients with TMJD-related pain per month. Splints or mouthguards (97.6 percent), self-care (85.9 percent) and over-the-counter or prescribed medications (84.6 percent) were the treatments most frequently used. The treatments dentists preferred to compare in an RCT were splint or mouthguard therapy (35.8 percent), self-care (27.4 percent) and medication (17.0 percent). CONCLUSIONS Most general dentists treat TMJD-related pain, and initial reversible care typically is provided. It is feasible to conduct an RCT in a dental PBRN to assess the effectiveness of splint or mouthguard therapy, self-care or medication for the initial management of painful TMJD. CLINICAL IMPLICATIONS There is an opportunity to do an RCT in a dental PBRN, which could lead to the development of evidence-based treatment guidelines for the initial treatment of TMJD-related pain by primary care dentists.

Long-term reliable change of pain scores in individual myogenous TMD patients. Eur J Pain 2012; 11:635-43.

Abstract
A within-patient change in pain score after treatment is statistically 'reliable' when it exceeds the smallest detectable difference (SDD). The aims of the present study were to: (i) determine SDDs for VAS-scores of pain intensity, for sufficiently long test-retest intervals to include most biological fluctuations, (ii) examine whether SDD is invariant to baseline score, and (iii) discuss the value of reliable change (RC) for detecting clinically important difference (CID) or as a possible indicator of successful treatment. SDDs were determined using duplicate data from 118 patients with myogenous Temporomandibular disorders: (1) VAS-scores of pain intensity from the masticatory system in a pre-treatment diary, and (2) VAS-scores of pain intensity from the hand (cold-pressor test). RC was determined in VAS-scores from a pre- and post-treatment questionnaire. The long-term SDD was 49mm. A regression analysis on duplicate VAS-scores showed that SDD was largely invariant to the baseline level. Because RC (change>SDD) exceeded CID, it might serve as an indicator of successful treatment. However, only 17% of the patients showed RC after treatment, mainly because the baseline was smaller than SDD in 67% of the patients thus making detection of any treatment effect impossible. For patients with possible detection (33%), the frequency of RC was 51%. If the detection threshold would be avoided by provoking pain in patients with a low baseline, a long-term RC in VAS-scores might occur in about half of all myogenous TMD patients and might then serve as an indicator of cases of treatment success.

Routines for interocclusal appliance therapy among general dental practitioners in a Swedish county. SWEDISH DENTAL JOURNAL 2012; 36:125-132.

Abstract
The aims of this study were to investigate what kind of interocclusal appliances that were chosen among Swedish dentists when treating temporomandibular disorders (TMD), the clinical rationale for the treatment, the diagnoses that warranted the appliance treatment, the use of adjunct TMD treatments and prognostic considerations, and possible differences in these respects between children/adolescents and adults with TMD, and, finally, possible differences between private practitioners and general practitioners in the public dental service. During the 12-months-period April 2009-March 2010 all general dental practitioners in the county of Jönköping, Sweden, were asked to fill in a questionnaire when performing a TMD treatment with an interocclusal appliance. A total of 394 questionnaires were filled in and returned, 216 (55%) from dentists in public dental service and 178 (45%) from private practitioners. It was found that in 40% of the cases, no pre-treatment recording of the functional status in the masticatory system had been made. The commonest reasons for the treatment were bruxism, headache, and replacement of a previous appliance. Less than half of the appliances made were hard acrylic appliances. Some kind of adjunct therapy had been made in 22% of the cases treated in public dental service. The corresponding figure for those treated by private practitioners was 25%. Therapeutic jaw exercises was the commonest adjunct therapy followed by selective occlusal adjustment. In the vast majority of cases, the dentists judged the prognosis of the treatment to be good. It is concluded that a large number of appliances made to treat TMD were soft appliances, especially in public dental service. This reflects a possible overuse of soft appliances at the expense of hard acrylic appliances. Furthermore, in a large number of cases, the treatment was performed without any pre-treatment registrations, and adjunct therapies were rarely used. In all these respects,there is an improvement potential for the treatment of TMD in general dental practice.

Abstract
The purpose of the present investigation was to identify the most frequent therapies and, in particular, the prescription patterns for occlusal splints for the management of craniomandibular disorders (CMDs) used by German general dentists and specialists. Additionally, the knowledge and opinion of the practising dentists were examined. All active members of the statutory dental insurance providers of the German North Rhine (n = 5,500) and the Westphalia-Lippe area (n = 4,984) were surveyed with a questionnaire by mail. Results indicated that occlusal splints were the first-choice therapy followed by physiotherapy and occlusal equilibration. In the preceding year, both general dentists and specialists made 30 occlusal splints on average. With regard to high-quality evidence-based recommendations, some statistically significant discrepancies between general dentists and specialists were detected. On the basis of the present data, it seems useful to consider intensifying the topic of CMDs and orofacial pain in future undergraduate dental curricula and in postgraduate training.

Abstract
OBJECTIVES To assess the prevalence of treatment and diagnosis of snoring and sleep apnea in the population of New South Wales Australia. METHODS Postal survey of 10,000 people randomly selected from the electoral roll, half aged 18 to 24 and half aged 25 to 64, with telephone follow-up for some nonresponders. Weighted prevalences are reported. RESULTS The overall response rate was 35.6% (18-24 n = 1421 and 25-64 n = 1879). One hundred and fifty-nine respondents reported seeking medical help for snoring or sleep apnea (6.3%, 95% confidence interval 5.46-7.12%), with 133 of these being aged 25 to 64. Fifty-one respondents reported subsequent treatment (2.0%; 95% CI 1.49-2.43), with some reporting more than 1 treatment. Continuous positive airway pressure was received in 17 cases, mandibular advancement splints in 9 cases, and upper airway or nasal surgery in 31 cases. Eighty-six reported receiving an overnight sleep study (polysomnography). Most surgical patients did not report having their sleep measured with a sleep study (22/31). CONCLUSIONS The population of New South Wales has had the longest potential exposure to continuous positive airway pressure. However, few of those in even the middle-aged group reported ever being recommended continuous positive airway pressure treatment. It is more common to have a surgical intervention for snoring or sleep apnea. Surprisingly, most surgical patients do not report any associated sleep study to quantify their snoring or sleep apnea or measure the efficacy of surgery. Since a substantial proportion of patients who experience snoring and sleep apnea are not assessed via a sleep study, it is necessary to increase awareness of undergoing such clinical procedures.

Abstract
OBJECTIVE Evaluation of the characteristics and dental treatments in a Brazilian series of idiopathic trigeminal neuralgia (ITN) patients. STUDY DESIGN Forty-eight subjects with ITN were interviewed and evaluated according to a systematized approach. RESULTS FINDINGS (a) location of the trigger zone, intraoral in 64.58%; (b) comorbidities, 18 patients (hypertension in 9); (c) treatment with dental procedures for ITN according to duration of pain (31), 44.44% (during the first year), 50.00% (1-5 years), 80.00% (5-10 years), and 100.00% (>10 years). There was no correlation between trigger zone location and the frequency of previous dental procedures (P=.667). There was significant statistical correlation between the number of patients who underwent dental treatments and the duration of ITN (P=.004). CONCLUSION (a) Demographic characteristics of this sample are similar to those described in the literature, (b) the dental procedures were not correlated with location of trigger zone, and (c) patients with long-lasting ITN had more number of previous dental procedures.

Abstract
An epidemiological sample of 114 subjects was followed longitudinally from the age of 15 to 35 years with regard to treatment received, treatment demand, and treatment need for temporomandibular disorders (TMD). Some kind of TMD treatment had been provided to 18% of the subjects during the 20-year follow-up period. Eighty-five percent of those who had received previous TMD treatment reported that the treatment had had a positive effect on their symptoms. The estimated present need for treatment was 11%, but, in line with several other investigations, the active demand for such treatment was much less (3%). From age 15 to 25 years, a small but gradual increase of clinical signs of dysfunction was found. From the age of 25 to 35 years, however, a significant reduction of such signs was noted. One explanation for this reduction of clinical signs and symptoms of TMD might be the stomatognathic treatment received. It was concluded that 18% of the subjects had received some TMD treatment during the 20-year follow-up period. Only 3% still had a demand for such treatment at age 35.

Abstract
UNLABELLED Occlusal splints (Michigan splints, night/bite guards or bite-raising appliances) can be an effective, inexpensive and reversible treatment for a wide range of dental problems. OBJECTIVE The aim of this study was to analyse retrospectively the provision of occlusal splint ('Michigan' type) in general dental practice, following a prescription by a restorative dental consultant. METHOD One hundred patients were recruited from consultant clinics in a department of conservative dentistry during 1995 and 1996. All patients were prescribed a maxillary, full-coverage, heat-cured, acrylic-resin splint (Michigan splint) as part of a treatment plan. An explanatory letter and questionnaire were sent to all patients and to their referring general dental practitioner in 1997 and 1998. RESULTS A response rate of 79% was achieved in obtaining completed questionnaires from both patients and general dental practitioners. Of respondents 43% (34/79) received an occlusal splint of some form. A small proportion of the respondents (16.5% [13/79]) received a Michigan splint as prescribed. Irrespective of the type of appliance provided, most patients (82% [28/34]) found them helpful. Of those who did not receive an occlusal splint, 38% (17/45) of patients felt financial implications deterred them from obtaining an appliance. Other common reasons for non-provision included: patients felt that symptoms had improved (18% [8/45]) and patients did not agree with treatment (18% [8/45]). The general dental practitioners had similar opinions to their patients. DISCUSSION These findings raise some serious doubts on the efficacy of consultant clinic advice in the prescription of occlusal splints in general dental practice. The financial and educational issues raised by this study will need to be addressed to improve service provision. CONCLUSION The results of this study indicate that 16.5% of patient respondents prescribed a Michigan splint at a consultant clinic received such an appliance in general dental practice.

Abstract
The purpose of this study was to evaluate the effect of stabilization splint therapy on occlusal force in patients with masticatory muscle disorders (MD). Six female patients with myalgia or myofascial pain participated in this study. The occlusal points and load on the dental arch in maximum clenching was measured using the computerized system with Dental Prescale(R) before and after the use of the splint. There were no significant changes in the number of occlusal points, mean occlusal pressure, and asymmetry in occlusal balance between before and after the use of the splint. However, there were significant differences in the extent of the area of occlusion and in the integrated occlusal loads. The integrated occlusal load converged to the normal level with the use of the splint. From the results of this study, it is suggested that the use of the stabilization splint has the effect of normalizing the occlusal force.

Abstract
In a prospective study, 95 patients with mild to moderate obstructive sleep apnoea (OSA) were randomised to receive either surgical treatment, uvulopalatopharyngoplasty, (4-6 patients) or treatment with a nocturnal dental appliance for mandibular advancement (49 patients). Of the 49 dental appliance patients, 37 completed the 12-month follow-up. The aim of this study was to evaluate the effects and adverse events of dental appliance treatment from a one-year perspective. Somnography was employed to measure treatment effects before and 12 months post-treatment. At the 12-month control, somnography was performed twice: the first time with the dental appliance and the second time without it. Adverse events were recorded 2 weeks and 3, 6, and 12 months after treatment was initiated. The patients used the dental appliance on average 6 nights/week. After 12 months of treatment, the apnoea, apnoea/hypopnoea, oxygen desaturation, and snoring indices decreased significantly. Ninety-five per cent of the patients reduced their apnoea index by > or = 50% and 78% of the patients were normalised following treatment. At the somnographic registration without the dental appliance, the values were found comparable to what they were before treatment. Mandibular mobility and occlusion were constant throughout the study. The adverse events resulting from using the dental appliance were relatively minor and infrequent, and no serious complications were observed except for two patients who reported pain from the temporomandibular joint. In conclusion, the dental appliance has been shown to be a valuable treatment method for mild to moderate OSA with few adverse events in the stomatognathic system or other complications.

Abstract
Occlusal treatments (occlusal splints and occlusal adjustment) are controversial but widely used treatment methods for temporomandibular disorders (TMD). To investigate whether studies are in agreement with current clinical practices, a systematic review of randomized controlled trials (RCTs) of occlusal treatment studies from the period 1966 to March 1999 was undertaken. Eighteen studies met the inclusion criteria, 14 on splint therapy, and 4 on occlusal adjustment. The trials were scored using the quality scale presented by Antczak et al., 1986a (A.A. Antczak, J. Tang, T.C. Chalmers, Quality assessment of randomized control trials in dental research. I. Methods, J. Periodontal Res. 1986a;21:305-314). The overall quality of the trials was fairly low, the mean quality score was 0.43/1.00 (range 0.12-0.78). The most obvious methodological shortcomings were inadequate blinding, small sample sizes, short follow-up times, great diversity of outcome measures and numerous control treatments, some of unknown effectiveness. Splint therapy was found superior to 3, and comparable to 12 control treatments, and superior or comparable to 4 passive controls, respectively. Occlusal adjustment was found comparable to 2 and inferior to one control treatment and comparable to passive control in one study. Because of the methodological problems, only suggestive conclusions can be drawn. The use of occlusal splints may be of some benefit in the treatment of TMD. Evidence for the use of occlusal adjustment is lacking. There is an obvious need for well designed controlled studies to analyse the current clinical practices.

Abstract
The aim of this study was to compare the effects of hard and soft splints on the activity of the anterior temporalis and masseter muscles. Surface EMG recordings were made from these muscles during clenching at 10% of maximum, 50% of maximum and at maximum clench, both before and after insertion of a hard splint. This sequence was then repeated with a soft splint. The relative level of activity in the anterior temporalis and masseter muscles at all three activity levels was quantified by means of an Activity Index, which provides a measure of the balance of activity in the masseter relative to the activity in the anterior temporalis muscle. It was found that hard splints led to a decrease in EMG activity in relation to activity with no splint in both muscles at maximum clench and particularly the anterior temporalis. Soft splints produced a slight increase in activity of both muscles, but particularly the masseter muscle. The Activity Index indicated a shift in the balance of activity away from the anterior temporalis muscles with both splints, particularly at 10% of the maximum clenching level. It is possible that the decrease in activity of the temporalis muscles relative to the masseter muscles may be a factor in the therapeutic effect of both a hard and a soft splint, although the decrease is clearly greater with the hard splint.

Abstract
STATEMENT OF PROBLEM Patients are often treated for signs and symptoms in the masticatory musculature, which may be manifested as pain and/or conditions that cause difficulty in recording jaw relation records. A quick, easy method to alleviate these signs and symptoms would be helpful. PURPOSE This study measured the effect of a prefabricated anterior bite stop on the electromyographic activity of the anterior temporalis, posterior temporalis, masseter and anterior digastric during clenching, and grinding tasks. MATERIAL AND METHODS A prefabricated anterior bite stop was fabricated for 30 randomly selected subjects. Electromyographic surface electrodes were placed on the right and left sides of these muscles. Electromyographic activity was measured during clenching and grinding both with and without the anterior bite stop. RESULTS The anterior bite stop had a significant effect in decreasing electromyographic activity for both clenching and grinding for all the tested muscles, except the anterior digastric. CONCLUSIONS For this patient population, the ready-made anterior bite stop reduced electromyographic muscle activity for the anterior and posterior temporalis and the masseter muscles during both clenching and grinding.

Abstract
The study evaluated 646 patients treated in a full time TMD practice with a new survey tool based on a patient self-report questionnaire. It would appear that this new approach to practice evaluation has not been previously reported in the literature. The results indicate that the average patient has a significant time delay of 24 to 120 months from onset of symptoms to the beginning therapy and that the majority of patients see three or more practitioners before reaching the TMD therapist. Most significantly, there are strong indications that early intervention and persistent compliance with prescribed therapy produces the highest level of success. Valuable practice statistics regarding patient treatments, patient outcomes and modalities of therapy have proven intensely useful in managing the patients, educating the public, communicating with the referral base, as well as in negotiating participation agreements with managed care institutions.

Use and abuse of bite splints. COMPENDIUM OF CONTINUING EDUCATION IN DENTISTRY (JAMESBURG, N.J. : 1995) 1999; 20:249-54, 256, 258-9; quiz 260.

Abstract
Bite splints are often used in the treatment of patients with oral parafunctions, temporomandibular joint (TMJ) dysfunction, or temporomandibular disorders. The most common reasons for prescribing a bite splint are to protect the teeth in patients with bruxism, to improve jaw-muscle and TMJ function, and to relieve related pain. The risk for negative side effects is small in conservative bite splint treatment. Complications from long-term use of splints, however, can be severe and irreversible. The risks are especially high when mandibular advancement splints, or splints that make contact only with parts of the opposing dentition, are used for more than 4 to 6 weeks without appropriate supervision. As a general rule, a dentist should not encourage a patient to use any type of splint for more than a few months except for cases in which the teeth need to be protected because of persistent oral parafunctions. Appropriate record keeping, including signed consent forms, is necessary; when neglected, it becomes difficult for the dentist to defend himself from false accusations of malpractice.

Abstract
Because of a lack of substantial scientific data, the efficacy of occlusal therapy for the management of temporomandibular disorders (TMD) is still controversial. Of a total of 1405 consecutive TMD patients examined over the last 10 years, 369 (26.3%) were determined to have completed treatment at least 1 year before the present survey. A sample questionnaire was mailed to each patient in this sample population. The questionnaire failed to reach 46 patients; of the 323 patients who received the questionnaire, 260 (80.5%) responded. The mean duration of time between their last visit and this survey was 3.7 years. The questionnaire elicited information on treatment outcomes, present treatment needs, and current signs and symptoms. Participants were divided into two treatment groups: (a) those who underwent some occlusal therapies (Phase II) following successful reversible therapies (Phase I) (20 men and 114 women); and (b) those who underwent reversible therapy only (33 men and 93 women). Participants were further differentially diagnosed into five diagnostic subgroups of TMD, based on the clinical examination at the initial visit, tomography, and, for some patients, magnetic resonance imaging. The subgroups included myalgia, arthralgia, anterior disc displacement with an without reduction, and osteoarthritis/osteoarthrosis. Only 12.3% of the total population surveyed reported lack of improvement to an acceptable level and further need for treatment. The remaining patients reported satisfactory results in the reduction of TMD symptomatology and no further need for treatment, because their symptoms had either disappeared or improved to an acceptable level. Regardless of treatment groups and diagnostic subgroups, the current subjective signs and symptoms were negligible in most patients, and mean mouth openings were in the normal range. No particular diagnostic subgroups seemed to have significantly better outcome following Phase II occlusal therapy. These results suggest that the majority of TMD signs and symptoms improve to an acceptable level with only reversible therapy, and the long-term value of additional occlusal therapy following reversible therapy is minimal. Therefore, permanent occlusion-changing therapies apparently are not generally needed to maintain TMD symptom reduction over time.

Abstract
OBJECTIVE To assess the long-term follow-up of patients successfully treated for disc displacement with anterior repositioning splint therapy and patients successfully treated for pain dysfunction syndrome with stabilisation therapy. DESIGN Retrospective analysis. SETTING Dental school clinic unit. METHODS Maintenance of improvement was assessed by a postal questionnaire or by direct telephone contact 3 years after cessation of splint treatment. RESULTS 90% of patients successfully treated for disc displacement with reduction and 88% of patients successfully treated for pain dysfunction reported maintenance of improvement after 3 years. In both groups the reported improvement was independent of the pattern of splint usage. CONCLUSIONS The short-term use of an appropriate occlusal splint for a specific temporomandibular disorder leads to a long-term resolution of the problem.

Abstract
Fifty-eight consecutive patients in a referral based practice seeking treatment for complex chronic painful temporomandibular joint (TMJ) disease were enrolled in a prospective study to assess the recapture of displaced disks by anterior repositioning appliances (ARA) and the improvement in disk position in those disks that did not fully recapture. After standard clinical workup, including assessment of pain, maxillary and mandibular ARAs were constructed which repositioned condyles to the Gelb 4/7 position as determined by cephalometrically-corrected linear tomograms. Multi-planar magnetic resonance imaging (MRI) was performed immediately before and after insertion of the mandibular ARA, showing three-dimensional recapture of disks in 85% and improved disk position in 6% of reducing displacements. Disk position was improved in 28% of nonreducing joints, but none were totally recaptured. Recapture or improvement was achieved in 91% of reducing, 28% of nonreducing, and 63% of all joints with internal derangements. Initial disk position, reduction on opening and recapture by ARA were statistically independent of patient age, number of teeth missing, number of third molars missing, malocclusion (Angle's class), overjet, overbite, prosthetic appliances, and previous orthodontic treatment. It was concluded that ARA therapy provided effective recapture of displaced TMJ disks that reduce upon mouth opening. In this population of patients with chronic TMJ pain, previous dental treatment had no statistically significant effect on the incidence of internal derangement or on disk recapture by ARA therapy. There was no evidence of adverse effect from orthodontics, prosthetics, or any other dental care.

Abstract
One the different interpretation of the pathological and clinical evolution of TMJ dysfunctions, the most-common of these pathologies is the condyle-disk uncoordination. This study analyzes the evolution of the treatment on the sample of patients affected by TMJ dysfunction and examined at the maxillo-facial department of the University of Rome "La Sapienza". After the TMJ dysfunction has been diagnosed the patients were informed of the individual therapeutic program which consisted of a temporary and definitive occlusal therapy. The aim of this scientific work is to control the efficiency within this therapeutic program in relation to the uncoordination of TMJ. In order to validate this approach the study was compared with another that considered the evolution of TMJ pathology in patients examined at the first diagnostic, visit but who had not undergone any treatment.

Abstract
Snoring and obstructive sleep apnea (OSA) are related to narrowing of the upper airway. A mandibular advancement splint (MAS) could improve both conditions by increasing oropharyngeal and hypopharyngeal dimensions. The effects of a MAS on snoring and OSA was evaluated 3.5 +/- 2.1 (mean +/- SD) mo after issue in 57 subjects with habitual loud snoring, 39 of whom had an apnea-hypopnea index (AHI) > or = 10. Assessment was by questionnaire (all subjects) and polysomnography (51 subjects, 47 male) including measurement of sound intensity. Use of the MAS was randomized to first or second half of study. Snores were scored where inspiratory noise was greater than 5 dB above background. Total sleep time, sleep efficiency, % REM sleep, and % sleep spent supine were similar (p > 0.05) with and without the MAS. Snores per sleep minute, corrected for time in apnea, and sound intensity of snores (% snores > or = 50 dB) decreased with the MAS from 11.0 +/- 5.8 and 42.0 +/- 25.0% to 9.0 +/- 6.0 (p < 0.01) and 26.2 +/- 25.2% (p < 0.01), respectively. Using the MAS significantly improved OSA: AHI decreased from 32.2 +/- 28.5 to 17.5 +/- 22.7 (p < 0.01) and arousal index decreased from 31.4 +/- 20.6 to 19.0 +/- 14.6 (p < 0.01). AHI decreased to < 20 with the MAS in 12 of 17 subjects where untreated AHI was between 20 and 60, and in 2 of 9 subjects where untreated AHI was > 60. Forty-five patients continued to use the MAS regularly.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The long-term effects were studied of a full arch maxillary plane occlusal splint on chronic signs and symptoms of craniomandibular disorders (CMD) in 31 patients with nocturnal bruxism. The results revealed that the score and intensity of signs and symptoms in this type of patient fluctuate from day to day and even within a single day. In spite of continuation of nocturnal bruxism, the symptoms of CMD were cured or improved with the long-term use of the occlusal splint. However, in general, the symptoms recurred after discontinuation of splint therapy. The therapeutic mechanisms of the splint during sleep are discussed.

Abstract
During post-treatment examination the effect of splint therapy on 14 temporomandibular joints (TMJ) with anterior disk displacement were examined using clinical and instrumental findings and magnet resonance imaging (MRI) to judge the therapeutical success of the treatment from an orthodontic perspective. A stable reposition of the TMJ disk was achieved in four joints, which showed no relapse over a two-year period of observation. The success of the therapy was dependent on the extent of the tissue damage to the TMJ and also on patient compliance. The MRI yielded therapeutically valuable information, which is not revealed in the clinical-instrumental analysis, on the tissue structure of the disk and the ligaments. In certain cases the use of MRI is necessary to confirm the clinical diagnosis.

Abstract
A survey of 10,000 members of the American Dental Association was conducted in order to identify the most commonly used treatments for myofascial pain dysfunction (MPD). A questionnaire was used in which MPD was defined, all treatments (including referral) were listed, and a percentage-of-use estimate for each treatment was requested. Results from 2,544 questionnaires showed that the most commonly used treatments are: flat plane splints with anterior/canine guidance or posterior group function, occlusal equilibration, thermal packs, relaxation/stress management training, diet counseling, and medications with anti-inflammatory (nonopioid) analgesic and muscle relaxant properties. The results also showed considerable variation in the ways common treatments are performed. A call is issued for systematic and careful research on the outcomes of these and other treatments and their major variations.
