Over-the-counter bite splints: A randomized controlled trial of compliance and efficacy.

BACKGROUND: Occlusal splints are often used to curb the impacts of sleep bruxism (SB) on the dentition, and over-the-counter (OCT) options are becoming increasingly popular. OTC splints are usually fabricated at home by patients, but not routinely evaluated by dental professionals. It is unclear how OCT splints compare with more traditional splints that receive dental oversight. OBJECTIVES: The present randomized controlled study tested how an OTC splint compared with a gold standard bite splint in terms of patient compliance (primary outcome) and efficacy (secondary outcomes). METHODS: Sixty-seven subjects were randomly assigned to receive either the OTC (SOVA, N = 35) splint or the gold standard "Michigan" bite splint (MI, N = 32), with 61 completing the study (SOVA, N = 30; MI, N = 31). OTC-splint subjects were required to fabricate their splints to clinically acceptable standards. Both groups wore the splints nightly for four months. Compliance was measured via daily diary. Efficacy outcomes evaluated stability, retention, periodontal health, night-time rhythmic masticatory muscle activity (RMMA), and material wear. RESULTS: OTC-splint subjects had difficulty fabricating splints to clinically acceptable standards. The number of night-time RMMA bursts was significantly greater for the OTC splint group. Compliance and all other efficacy measurements were not significantly different between-groups. CONCLUSIONS: The results support the potential use of OTC splints for curbing the impacts of SB. However, the results strongly suggest that dentists should be actively engaged in overseeing patients' use of self-fabricated appliances. This clinical trial is registered at ClinicalTrials.gov, Identifier number NCT02340663.

The course of pain intensity and frequency of adolescents treated because of temporomandibular disorders: A long-term follow-up.

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.

Dose-dependent effects of mandibular advancement on optimal positive airway pressure requirements in obstructive sleep apnoea.

BACKGROUND: Implementation of mandibular advancement splint (MAS) therapy as first-line treatment for obstructive sleep apnoea (OSA) is hindered by inter-individual variability of treatment outcomes and lack of robust patient selection methods. Optimal continuous positive airway pressure (CPAP) requirement provides an estimate of airway collapsibility severity, and high CPAP requirements predict MAS therapy failure in retrospective studies. Thus, understanding the effects of mandibular advancement on optimal CPAP requirements may enhance optimisation of patient selection for MAS therapy. OBJECTIVE: This study aims to determine dose-dependent effects of mandibular advancement on optimal CPAP requirements in OSA. METHODS: Prior to MAS therapy initiation, participants with OSA (apnoea-hypopnea index (AHI) > 10 events/h) underwent a research polysomnogram in which a remotely controlled mandibular positioner (RCMP) was used to determine dose-response effects of varying mandibular advancement positions (0% 'habitual bite' and 25, 50, 75 and 100% of maximum mandibular advancement, in random order) on optimal CPAP requirements. A separate polysomnography determined treatment outcome. Data are presented as mean ± SD or median (1st-3rd quartiles). RESULTS: Seventeen participants (age = 47 ± 9 years, body mass index = 26 kg/m2 (23-27), apnoea-hypopnea index = 18 events/h (14-44) and minimal oxygen saturation = 84 ± 7%) were studied. Optimal CPAP requirements were reduced with mandibular advancement in a dose-dependent manner (8.9 ± 2.4 vs. 7.9 ± 2.8, 6.4 ± 1.8, 5.7 ± 1.9 and 4.9 ± 1.8 cmH2O; respectively, p < 0.0001). Compared with non-responders, responders to MAS therapy had lower AHI, lower arousal index and greater MinSaO2 at baseline. Optimal CPAP requirements at 0% mandibular advancement (or other positions) were not different between groups. CONCLUSIONS: Increasing mandibular advancement lowers optimal CPAP requirements in a dose-dependent manner. This supports prior work indicating a beneficial effect of MAS on upper airway collapsibility.

Interventions to reduce bruxism in children and adolescents: a systematic scoping review and critical reflection.

The aim of the present study was to perform a critical reflection about intervention options for bruxism reduction in children and adolescents. Search was conducted based on the PICO-structured question: "What are the intervention options to reduce bruxism in children/adolescents?". No language, year, or study design restrictions were imposed. Studies reporting interventions to reduce bruxism in children (< 10) and adolescents (10 to 19 years old) were included. Reviews and letters to editors were not included. From 2723 records, 17 papers were included. Included studies were primarily randomized clinical trials performed in Brazil (35.3%) and using different criteria for the diagnosis of bruxism. Reduction in self-reported bruxism and headaches associated with bruxism were observed in studies that used medications (hydroxyzine/trazodone/flurazepam), occlusal splints, orthodontic interventions, and psychological and physical therapy interventions. Reduction in Rhythmic Masticatory Muscle Activity was observed with the use of the occlusal splint and in orthodontic interventions. Alternative treatments (medicinal extracts such as Melissa officinalis-L) have shown inconclusive results.Conclusions: Several intervention options are available to inhibit or reduce bruxism activity. The respective indication, contraindications, and side effects of each treatment option must be assessed individually and carefully, taking into account that bruxism is not considered a disorder in otherwise healthy individuals.What is known• Biological and psychological factors have been strongly correlated to the development of bruxism• Bruxism prevalence ranging from 6 to 50% in childrenWhat is new• Reduction in self-reported bruxism and headaches associated with bruxism were observed in studies that used medication (Hydroxyzine/ Trazodone/ Flurazepam), occlusal splints, orthodontic interventions, psychological, and physical therapy interventions• A reduction in Rhythmic Masticatory Muscle Activity was observed with the use of the occlusal splint and orthodontic interventions. Alternative treatments (medicinal extracts such as Melissa officinalis L) show inconclusive results in respect of the reduction in bruxism.

Long-Term Objective Adherence to Mandibular Advancement Device Therapy Versus Continuous Positive Airway Pressure in Patients With Moderate Obstructive Sleep Apnea.

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.

Comparison of kinesio taping and occlusal splint in the management of myofascial pain in patients with sleep bruxism.

OBJECTIVES: To evaluate the efficacy of Kinesio taping (KT) in patients with sleep bruxism (SB) and to determine whether KT may be an alternative for occlusal splint (OS) for the treatment of SB. MATERIALS AND METHODS: Sixteen patients with SB were treated with KT (kinesio group) and 18 patients were treated with OS (splint group). Masseter and temporal muscle pressure pain thresholds (MPPT and TPPT), visual analogue scale (VAS) values and mouth opening measurements of patients were compared before treatment, and at the 1st and 5th weeks of treatment. RESULTS: Both KT and OS treatments significantly reduced muscle pain, decreased VAS values, and increased mouth opening measurements. No statistically significant difference was found between the kinesio and splint groups in terms of MPPT, TPPT, VAS and mouth opening values before treatment and at the 1st and 5th weeks of treatment except for TPPT values at 1st week of treatment where the TPPT values of the kinesio group were significantly higher than the splint group (p< 0.05). CONCLUSIONS: KT was identified as an easy-to-use treatment method for bruxism and was found to reduce muscle pain and increase mouth opening. KT is at least as effective as OS for the treatment of SB.

Long-term treatment outcome for adolescents with temporomandibular pain.

OBJECTIVES: This study aims to evaluate long-term, self-perceived outcome in adulthood for individuals treated as adolescents for temporomandibular disorder (TMD) pain in two previous randomized controlled trials (RCTs). MATERIALS AND METHODS: The study included 116 subjects (81% females) treated for frequent TMD pain in two separate RCTs 5-21 (M = 14.8, SD =4.9) years previously. Treatment consisted of occlusal appliance (OA) (n = 41, 35.3%) or relaxation training (RT) combined with information for the control (Co) group (n = 50, 43.1%), both compared to non-responders receiving additional, sequential treatment (ST) in a crossover study (n = 25, 21.6%). Participants answered a questionnaire on their experience of frequency and intensity of TMD pain impaired chewing capacity and daily social activities, help-seeking behaviour and treatment, general health, other pain, and depressive symptoms. RESULTS: Older participants reported lower levels of frequency and intensity of TMD pain, impairment, and depressive symptoms, as well as better general health. Females reported more frequent and more intense TMD pain, greater impairment and more often reported 'other pain' compared to males. Non-responders receiving ST experienced significantly more TMD, and other pain and higher impairment levels compared to other groups. Those treated with an OA had sought additional treatment significantly less often since the RCTs than ST and RT/Co-treated individuals. CONCLUSIONS: Adolescents treated with OA showed somewhat better sustained improvement over the extended follow-up period than those treated with RT/Co. Non-responders to treatment and females exhibited a poorer outcome. These groups need particular attention and extended or different treatments to achieve a better long-term outcome.

Can an NTI-tss device be effective as a first-line therapy in patients with TMD myofascial pain?

This study was conducted to evaluate whether integrating a nociceptive trigeminal inhibition-tension suppression system (NTI-tss) device with first-line therapy of myofascial pain, which includes guidance, assurance, counselling and behavioural changes, would be more effective in alleviating symptoms. This randomised controlled clinical trial included 40 patients who were clinically diagnosed with myofascial pain according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Patients were randomly divided into two groups: the first group comprised patients who received guidance, assurance, counselling and behavioural changes; an NTI-tss device was integrated to this protocol in the second group. Both groups exhibited reduction in pain levels and improvement of jaw function compared with baseline values, but the difference was not significant. Both groups demonstrated improvements in 6 weeks; however, the integration of NTI-tss device into the therapy protocol did not provide any additional benefit in relieving symptoms of myofascial pain.

Laser Therapy and Occlusal Stabilization Splint for Temporomandibular Disorders in Patients With Fibromyalgia Syndrome: A Randomized, Clinical Trial.

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.

Obstructive sleep apnoea: patients' experiences of oral appliance treatment.

Over the past few decades, there has been a pronounced increase in the number of patients being treated by general dental practitioners for obstructive sleep apnoea (OSA). The purpose of this study was to survey the care and patient experiences and the self-reported effectiveness of OSA treatment with an oral appliance (OA) incorporating mandibular advancement. The design was a retrospective, cross-sectional study, with follow-up between 6 months to 1 year after commencement of treatment. A survey form was posted to 1150 subjects, identified in the regional register over a 1-year period as having been treated with an OA for OSA. The questionnaire comprised 70 questions and assertions in various domains, such as general health/lifestyle, changes in symptoms/quality of life and sleep-related experiences, daytime sleepiness, changes in life situation, evaluation of treatment and the value of treatment. The overall response rate was 64% (n = 738). Treatment with OA gave relief of symptoms in 83% of the respondents. Quality of life, somatic and cognitive symptoms improved significantly in patients who used the appliance frequently (P < 0·001). Daytime sleepiness decreased significantly (P < 0·001). Treatment satisfaction and willingness to recommend the similar treatment to a friend were high (>85%). OA treatment of OSA by general dental practitioners is a safe procedure. Most of the survey respondents experienced relief of symptoms. Those who used their appliance frequently reported improvement in quality of life, somatic and cognitive symptoms. Excessive daytime sleepiness was reduced in the majority of the patients under treatment.

Effect of temporomandibular disorder therapy on otologic signs and symptoms: a systematic review.

The most common temporomandibular disorders (TMD) signs and symptoms are related to muscle sensitivity through palpation, restricted mouth opening, asymmetric mandibular movements, joint sounds, pain and otologic signs and symptoms. To date, counselling, occlusal splints, exercises, biofeedback and acupuncture are examples of conservative modalities proposed for TMD therapy. The aim of this systematic review was to investigate the effect of these conservative therapies for TMD on otologic signs and symptoms. The authors searched the following electronic databases published up to 1st May 2015: PubMed, LILACS, Scopus, Web of Science and Science Direct with no time or language limitations. Using a two-phase selection process, the authors identified 08 articles and used them to conduct a qualitative analysis. Methodological quality of each article was performed with the aid of 'Quality Assessment of a Cohort Study' and 'Quality Assessment of a Randomized Clinical Trial', developed by the Dutch Cochrane Centre, a centre of the Cochrane Collaboration. This systematic review showed in seven of the eight studies included that a total or partial resolution of otologic complains occurred after counselling, exercise therapies and occlusal splint therapy. Upon the limitations of the studies included in this systematic review, the present outcomes suggested that there is insufficient evidence in favour or against the conservative therapies for TMD on changes in otologic signs and symptoms. Thus, further studies with a higher level of evidence and more representative samples should be conducted to better understand the relationship of TMD therapy changes on otologic complains.

Factors associated with clinical decision-making in relation to treatment need for temporomandibular disorders.

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.

[THE ROLE OF STABILIZATION SPLINT IN THE TREATMENT OF TEMPOROMANDIBULAR DISORDERS]. / ULOGA STABILIZACIJSKE UDLAGE U LIJECENJU TEMPOROMANDIBULARNIH POREMECAJA.

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.

The effect of intermittent use of occlusal splint devices on sleep bruxism: a 4-week observation with a portable electromyographic recording device.

This randomised controlled study investigated the effect of intermittent use of occlusal splints on sleep bruxism compared with that of continuous use by measuring masseter muscle electromyographic activity using a portable electromyographic recording system. Twenty bruxers were randomly allocated to the continuous group and intermittent group. Subjects in the continuous group wore stabilisation splints during sleep for 29 nights continuously, whereas those in the intermittent group wore splints during sleep every other week, that is they used splints on the 1st-7th, 15th-21st and 29th nights. Electromyographic activity of the masseter muscle during sleep was recorded for the following six time points: before (baseline), immediately after, and 1, 2, 3 and 4 weeks after the insertion of a stabilisation splint. The number of nocturnal masseter electromyographic events, duration and the total activity of sleep bruxism were analysed. In the continuous group, nocturnal masseter electromyographic events were significantly reduced immediately and 1 week after the insertion of the stabilisation splint, and duration was reduced immediately after the insertion (P < 0·05, Dunnett's test), but no reduction was observed at 2, 3 and 4 weeks after insertion. In the intermittent group, nocturnal masseter electromyographic events and duration were significantly reduced immediately after and also 4 weeks after insertion of the stabilisation splint (P < 0·05, Dunnett's test). The obtained results of the present exploratory trial indicate that the intermittent use of stabilisation splints may reduce sleep bruxism activity for a longer period compared with that of continuous use.

Preservation of Hypermobile Teeth by Establishing Posterior Occlusal Support Using Implant Prostheses: A 5-Year Follow-Up.

For patients with periodontally compromised, hypermobile teeth, implant-supported fixed dental prostheses (FDPs) or removable dentures are often used after extracting mobile teeth. The loss of native teeth may carry social consequences, depending upon the patient's age, state of health, and degree of social functioning. This report represents successful stabilization and preservation of questionable, hypermobile teeth that have been damaged by traumatic occlusion due to the loss of posterior support with a cross-arch splinted FDP, as well as the implementation of posterior support using implant-supported prostheses.

The feasibility of a clinical trial of pain related to temporomandibular muscle and joint disorders: the results of a survey from the Collaboration on Networked Dental and Oral Research dental practice-based research networks.

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.

Routines for interocclusal appliance therapy among general dental practitioners in a Swedish county.

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.

[Dental care during pregnancy]. / Enquête sur la prise en charge de la femme enceinte au cabinet dentaire.

AIM: to understand and analyze knowledge and practices of dentists regarding dental care during pregnancy using a questionnaire which focuses on the knowledge of the relationship between oral infections and complications of pregnancy, the attitude of practitioners on the implementation of dental care during pregnancy and the training of practitioners. RESULTS: 53.9% of pregnant women are not referred by an obstetrician. Only 59.8% of practitioners believe that dental anesthesia is not contraindicated, and most practitioners believe that the best time for care is the second trimester or after pregnancy. During pregnancy, practitioners realize the motivation for hygiene (90.7%), drainage of an abscess (82.2%), scaling (76.1%), the placement of a splint (74.1%), the treatment of caries (70%), and the removable prosthesis (67.2%). CONCLUSION: these results indicate the existence of a gap between the care of pregnant women and the state of the art in dental science, despite current clinical recommendations to deliver all necessary care to pregnant patients during the first, second and third trimester. Moreover, the results highlight the need to reinforce the initial training of dental students, but also to develop the training for practitioners in this field.

Therapies most frequently used for the management of bruxism by a sample of German dentists.

STATEMENT OF PROBLEM: At present, there is little information available on how practicing dentists manage bruxism patients with respect to conservative, reversible techniques as compared to irreversible techniques. PURPOSE: The purpose of this study was to determine the most commonly applied therapies used for the management of bruxism by German general dentists (GDs) and dental specialists. In addition, efforts were made to gather information on the knowledge and opinion of GDs and specialists regarding the role of occlusal interferences, in particular, on the development of sleep bruxism. MATERIAL AND METHODS: A 13-item questionnaire was developed and mailed to all active members of the statutory dental insurance providers of the German North Rhine (n=5500; 2006 roster) and the German Westphalia-Lippe area (n=4984; 2006 roster). Group differences were statistically analyzed using chi-square tests for the qualitative variables and Mann-Whitney U tests for the quantitative variables (α=.05). RESULTS: Occlusal splints were by far the most frequently prescribed therapy for the management of bruxism, followed by relaxation techniques, occlusal equilibration, physiotherapy, and prosthodontic reconstruction. The occlusal stabilization splint with canine protected articulation was the splint type most often prescribed, whereas respondents used unadjusted soft splints for approximately 8% of their bruxism patients. Comparison of the opinions of all responding practicing dentists with that of experts in regard to the statement that "sleep bruxism is caused by occlusal interferences" showed a significant difference between the 2 groups (P=.021). Eighty-five percent of the experts disagreed with this statement, and only 47.7% of the practicing dentists had the same opinion as the experts. CONCLUSIONS: Most practicing dentists seem to concur with current scientific recommendations, and express the opinion that the management of bruxism should predominantly be conservative and reversible; however, the findings of the present survey reveal diverse differences between GDs and dental specialists concerning the most frequently prescribed therapies. Moreover, the discrepancies detected in some areas, such as the use of irreversible techniques or the use of unadjusted soft splints, emphasize the need to more promptly transfer new knowledge in the field of bruxism from researchers to practicing dentists.

A survey on German dentists regarding the management of craniomandibular disorders.

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.
