Cost-effectiveness of treatments for temporomandibular disorders: biopsychosocial intervention versus treatment as usual

BACKGROUND: The authors conducted a randomized clinical trial to evaluate the cost-effectiveness of a biopsychosocial intervention with patients who are at high risk (HR) of progressing from acute to chronic TMD-related pain. METHODS: The authors classified 96 patients with acute TMD (less than six months' duration) as HR according to a predictive algorithm and randomized them into an early intervention (EI) or a nonintervention (NI) group. The NI group received a biopsychosocial treatment that included cognitive behavioral skills training and biofeedback. Both groups were followed up for one year. The authors collected TMD cost data throughout the year. RESULTS: The authors found that the EI group spent significantly fewer jaw-related health care dollars, relative to the NI group, from intake to the one-year follow-up. CONCLUSION AND CLINICAL IMPLICATIONS: The reduced jaw-related health care expenditures for patients in the EI group compared with expenditures for patients in the NI group at one year suggest that an early biopsychosocial intervention is a cost-effective measure in dealing with often unnecessarily costly TMD-related pain.     

Predoctoral teaching of temporomandibular disorders: a survey of U.S. and Canadian dental schools

BACKGROUND: In the United States and Canada, there are no specific curriculum guidelines for predoctoral dental education in the field of temporomandibular disorders (TMDs). This situation has the potential to cause confusion for new graduates. METHODS: The authors sent an 11-question survey regarding predoctoral teaching of TMDs to the appropriate faculty members in all U.S. and Canadian dental schools either electronically or via the postal service between June and December 2005. RESULTS: Predoctoral teaching of TMD--both didactic and clinical aspects--has progressed. Some schools, however, do not address these topics adequately, while others teach outdated concepts. CONCLUSIONS: Both qualitative and quantitative standards are needed to ensure that all predoctoral dental students learn about the diagnosis and treatment of nondental orofacial pain problems. Practice Implications. Owing to the lack of standardized predoctoral teaching of TMD, U.S. or Canadian patients with TMD or facial pain are at risk when seeking appropriate primary care for their problems.     

Reduced or painful jaw movement after collision-related injuries: a population-based study

BACKGROUND: The authors report the incidence of and factors associated with reduced and/or painful jaw movement after motor vehicle collisions that resulted in whiplash-associated disorders (WADs). METHODS: All adults filing collision-related personal injury claims during an 18-month period in Saskatchewan, Canada, were evaluated via questionnaire to determine demographic characteristics, precollision health (including jaw pain), collision parameters and collision-related symptoms, including reduced and/or painful jaw movement and injury-related neck pain. The authors excluded patients who were hospitalized for more than two days and those who sustained injuries as a pedestrian, bicyclist or motorcyclist. In determining incidence rates, the authors also excluded those who had had jaw pain before the collision. RESULTS: The incidence of reduced and/or painful jaw movement was 14.9 percent (n = 1,158), and it was higher in subjects with WADs (15.8 percent) than in those without WADs (4.7 percent; relative risk = 3.36, 95 percent confidence interval, 2.36 to 4.78). Within the WAD injuries, multivariable logistic regression revealed that the onset of reduced and/or painful jaw movement was associated with female sex; age < 50 years; having hit one's head in the collision; and postinjury symptoms of difficulty swallowing, ringing in the ears, dizziness or unsteadiness, and more intense neck pain. Collision parameters, such as head position at the time of the crash and headrest use and type, were not associated with onset of jaw symptoms. CONCLUSIONS: Reduced or painful jaw movement was more common in people with WADs than in those with other collision-related injuries. Among those with WADs, reduced or painful jaw movement was more common in women and younger people. CLINICAL IMPLICATIONS: Reduced or painful jaw movement is an important aspect of WADs, and more studies are needed to determine how to best assess and treat this problem.     

A pilot study of a chiropractic intervention for management of chronic myofascial temporomandibular disorder

BackgroundTemporomandibular pain has multiple etiologies and a range of therapeutic options. In this pilot study, the authors assessed the feasibility of conducting a larger trial to evaluate chiropractic treatment of temporomandibular disorders (TMDs).MethodsThe authors assigned 80 participants randomly into one of the following four groups, all of which included a comprehensive self-care program: reversible interocclusal splint therapy (RIST), Activator Method Chiropractic Technique (AMCT) (Activator Methods International, Phoenix), sham AMCT and self-care only. They made assessments at baseline and at month 2 and month 6, including use of the Research Diagnostic Criteria for Temporomandibular Disorders.ResultsThe authors screened 721 potential participants and enrolled 80 people; 52 participants completed the six-month assessment. The adjusted mean change in current pain over six months, as assessed on the 11-point numerical rating scale, was 2.0 (95 percent confidence interval, 1.1–3.0) for RIST, 1.7 (0.9–2.5) for self-care only, 1.5 (0.7–2.4) for AMCT and 1.6 (0.7–2.5) for sham AMCT. The authors also assessed bothersomeness and functionality.ConclusionsThe authors found the study design and methodology to be manageable. They gained substantial knowledge to aid in conducting a larger study. AMCT, RIST and self-care should be evaluated in a future comparative effectiveness study.Practical ImplicationsThis pilot study was a necessary step to prepare for a larger study that will provide clinicians with information that should be helpful when discussing treatment options for patients with TMD.     

An assessment of the usefulness of jaw kinesiography in monitoring temporomandibular disorders: Correlation of treatment-related kinesiographic and pain changes in patients receiving temporomandibular joint injections

BackgroundThe authors conducted a study in patients with temporomandibular joint (TMJ) osteoarthritis to assess whether treatment-related changes in pain levels and chewing ability coincide with a change in jaw kinesiographic (KG) parameters.MethodsThe authors selected 34 patients with a diagnosis of TMJ osteoarthritis that met Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) to undergo a cycle of five weekly arthrocentesis procedures with injections of 1 milliliter hyaluronic acid. They performed a permutation test to assess the correlation between changes across time (from baseline to end of treatment) in two clinical outcome parameters—pain level and chewing ability—and changes across time in the KG outcome parameters.ResultsThe authors observed improvement across time in both chewing ability (F = 8.328; P = .005) and pain level (F = 10.903; P = .002). The authors observed no significant changes in any KG variables. With minor exceptions, no significant correlations were shown between changes in the clinical and KG parameters during the treatment period.ConclusionsTreatment-related changes in pain levels and chewing ability in patients with TMJ osteoarthritis do not coincide with changes in KG parameters.Practical ImplicationsIf one assumes pain variables to be the primary outcome measures in assessing treatment of TMJ osteoarthritis, KG recordings of the jaw are not useful for monitoring TMJ osteoarthritis in the clinical setting.     

Craniofacial pain as the sole symptom of cardiac ischemia: a prospective multicenter study

BACKGROUND: Craniofacial pain can be the only symptom of cardiac ischemia. Failure to recognize its cardiac source can put the patient's life at risk. The authors conducted a study to reveal the prevalence of, the distribution of and sex differences regarding craniofacial pain of cardiac origin. METHODS: The authors prospectively selected consecutive patients (N = 186) who had had a verified cardiac ischemic episode. They studied the location and distribution of craniofacial and intraoral pain in detail. RESULTS: Craniofacial pain was the only complaint during the ischemic episode in 11 patients (6 percent), three of them who had acute myocardial infarction (AMI). Another 60 patients (32 percent) reported craniofacial pain concomitant with pain in other regions. The most common craniofacial pain locations were the throat, left mandible, right mandible, left temporomandibular joint/ear region and teeth. Craniofacial pain was pre-ponderantly manifested in female subjects (P = .031) and was the dominating symptom in both sexes in the absence of chest pain. CONCLUSIONS: Craniofacial pain commonly is induced by cardiac ischemia. This must be considered in differential diagnosis of toothache and orofacial pain. CLINICAL IMPLICATIONS: Because patients who have AMI without chest pain run a higher risk of experiencing a missed diagnosis and death, the dentist's awareness of this symptomatology can be crucial for early diagnosis and timely treatment.     

Tooth preservation or implant placement: A systematic review of long-term tooth and implant survival rates

BackgroundFor the past few decades, dental implants have served as reliable replacements for missing teeth. However, there is an increasing trend toward replacing diseased teeth with dental implants.Types of Studies ReviewedThe authors conducted a systematic review of long-term survival rates of teeth and implants. They searched the MEDLINE database for relevant publications up to March 2013. They considered studies in which investigators assessed the long-term effectiveness of dental implants or that of tooth preservation. They included only studies that had follow-up periods of 15 years or longer.ResultsThe authors selected 19 articles for inclusion. Investigators in nine studies assessed the tooth survival rate, whereas investigators in 10 studies assessed the implant survival rate. When comparing the overall long-term (that is, 15 years or more) tooth loss rate with that of implants, the authors observed rates ranging between 3.6 and 13.4 percent and 0 and 33 percent for teeth and implants, respectively. They could not perform a meta-analysis because of the substantial differences between the studies.Practical ImplicationsThe results of this systematic review show that implant survival rates do not exceed those of compromised but adequately treated and maintained teeth, supporting the notion that the decision to extract a tooth and place a dental implant should be made cautiously. Even when a tooth seems to be compromised and requires treatment to be maintained, implant treatment also might require additional surgical procedures that might pose some risks as well. Furthermore, a tooth can be extracted and replaced at any time; however, extraction is a definitive and irreversible treatment.     

Pain catastrophizing in dental patients: Implications for treatment management

Background”Pain catastrophizing“ refers to an exaggerated negative mental set brought to bear during an actual or anticipated painful experience. A patient's perception of a dental care experience as catastrophic can result not only in poor satisfaction with the therapy but also in avoidance of necessary treatments, resulting in the deterioration of oral health.MethodsThe author reviewed literature regarding pain catastrophizing regarding dental treatment as well as behavioral models related to catastrophizing.ResultsPeople who catastrophize show excessive attention to pain (rumination), exaggerate the threat value of pain (magnification) and feel unable to cope with their suffering (helplessness). During dental treatments, greater pain catastrophizing is associated with increased pain, dental anxiety and negative thoughts regarding pain and dental procedures.ConclusionsIt is important that clinicians identify dental patients who catastrophize so as to plan and provide the best treatment for their needs.Practical ImplicationsTo manage the care of patients who catastrophize, the clinician can actively probe patients' pain experience, help them reappraise threat, manipulate their attention to pain and improve dentist-patient communication.

Clinicians and researchers need a measure for monitoring the periodontal condition of their patients or study participants. The authors explored the utility of change in probing depth (PD) for predicting change in clinical attachment loss (CAL).MethodsThe authors used clinical trial data from 363 participants who had received nonsurgical treatment to describe associations between PD and CAL changes. They computed the association between PD and CAL changes—correlation, sensitivity, specificity, and positive and negative predictive values—according to tooth type, tooth site and initial PD.ResultsDepending on the subset of tooth sites, sensitivity of PD change to predict CAL change ranged from 18 to 74 percent; the highest sensitivity was at initially deep sites. Specificity and negative predictive value were higher than sensitivity and positive predictive value. Correlations between person-level mean PD and CAL changes ranged from 0.60 to 0.79 and were highest at initially deep sites.ConclusionsExcept at initially deep sites, PD change did not reliably predict CAL change. Clinicians and researchers who measure only PD may fail to identify teeth that lose or gain attachment.Clinical ImplicationsClinicians should consider monitoring CAL to detect changes in periodontal status more reliably. It is unknown if these findings apply to patients treated surgically or to prediction of tooth loss.     

A topical imiquimod-induced oral mucosal lichenoid reaction: A case report

Background.Imiquimod (IMI) is a topical immune response modifier used in the treatment of actinic keratosis and cheilitis. Actinic cheilitis is a potentially premalignant condition that requires therapeutic intervention. IMI therapy is noted for producing cutaneous and mucosal adverse effects. The authors report the case of an 88-year-old woman who was treated for actinic cheilitis of the upper lip with IMI and who consequently experienced an oral mucosal lichenoid reaction of the lower lip and right buccal mucosa.Results.The patient was treated successfully with high-dose steroid therapy, and the oral lesions resolved in 17 days.Conclusions.To our knowledge, this is the first case report regarding an IMI-induced oral mucosal lichenoid reaction. Clinicians should be aware of the potential of IMI to cause lichenoid reactions.Practical Implications.IMI is an efficacious therapeutic agent when used in the treatment of actinic cheilitis, but it is prone to cause oral mucosal side effects such as lichenoid reactions. Therefore, it is important for dentists to be knowledgeable concerning potential mucosal IMI side effects.     

Assessing the association between bisphosphonate exposure and delayed mucosal healing after tooth extraction

BackgroundTooth extraction in patients exposed to bisphosphonates (BPs) is considered a risk factor for osteonecrosis. The authors evaluated the time to mucosal healing and frequency of osteonecrosis after tooth extraction in participants exposed to BPs.MethodsThe authors compared wound healing after tooth extraction in participants exposed to BPs with that in control participants who had not been exposed to BPs. Variables included age, sex, type of BP therapy (oral or intravenous), BP exposure time and C-terminal telopeptide (CTX) test results. The authors followed up patients weekly or biweekly until healing was complete. They used multivariable analyses to model time to healing in the presence of covariates, and estimates provided hazard ratios (HRs) and 95 percent confidence intervals (CIs) adjusted for all variables in the model.ResultsThe authors enrolled 53 participants with BP exposure and 39 control participants. Postextraction healing was significantly longer in participants exposed to BPs (P < .001) than it was in control participants. One patient (1.9 percent) developed osteonecrosis. A Cox proportional hazards model in which the authors controlled for age, sex and CTX values showed that BP exposure alone significantly (adjusted HR, 0.27; 95 percent confidence interval, 0.16–0.48) increased mucosal healing time.ConclusionsThe study results showed that postextraction healing was impaired in patients exposed to BPs. CTX values were not associated with delayed healing after tooth extraction.Practical ImplicationsPostextraction healing was delayed in patients receiving BP therapy. However, the risk of developing osteonecrosis was low.     

Risk of adrenal crisis in dental patients: Results of a systematic search of the literature

BackgroundThe authors performed a systematic search of the literature to identify the frequency of, risk of experiencing and factors associated with adrenal crises in dental patients.MethodsThe authors searched PubMed and Ovid MEDLINE (1947-June 20, 2012) and Embase (1974-2012) for English-language articles related to cases of adrenal crisis in dentistry and extracted and analyzed data from the articles. The six authors determined whether the cases identified met a consensus definition of adrenal crisis.ResultsOf 148 articles identified in the initial screening, 34 articles were included in the final review, from which six cases met the criteria of adrenal crisis. The authors categorized four cases as “suggestive of adrenal crisis” and two cases as “consistent with adrenal crisis.” Risk factors were significant adrenal insufficiency, pain, infection, having undergone an invasive procedure, having received a barbiturate general anesthetic, and poor health status and stability at the time of presentation. The authors estimated risk to be less than one in 650,000 in patients with adrenal insufficiency.ConclusionsAdrenal crisis is rare in dental patients, with only six reports of it having been published in the past 66 years. Risk is associated with unrecognized adrenal insufficiency, poor health status and stability at the time of treatment, pain, infection, having undergone an invasive procedure and having received a barbiturate general anesthetic.Clinical ImplicationsRisk of adrenal crisis is reduced through proper evaluation of the patient, identification of risk factors and following appropriate preventive measures.     

Restoration of noncarious tooth defects by dentists in The Dental Practice-Based Research Network

BackgroundThe authors conducted a study to quantify the reasons for restoring noncarious tooth defects (NCTDs) by dentists in The Dental Practice-Based Research Network (DPBRN) and to assess the tooth, patient and dentist characteristics associated with those reasons.MethodsData were collected by 178 DPBRN dentists regarding the placement of 1,301 consecutive restorations owing to NCTDs. Information gathered included the main clinical reason, other than dental caries, for restoration of previously unrestored permanent tooth surfaces; characteristics of patients who received treatment; dentists’ and dental practices’ characteristics; teeth and surfaces restored; and restorative materials used.ResultsDentists most often placed restorations to treat lesions caused by abrasion, abfraction or erosion (AAE) (46 percent) and tooth fracture (31 percent). Patients 41 years or older received restorations mainly because of AAE (P < .001). Premolars and anterior teeth were restored mostly owing to AAE; molars were restored mostly owing to tooth fracture (P < .001). Dentists used directly placed resin-based composite (RBC) largely to restore AAE lesions and fractured teeth (P < .001).ConclusionsAmong DPBRN practices, AAE and tooth fracture were the main reasons for restoring noncarious tooth surfaces. Pre-molars and anterior teeth of patients 41 years and older are most likely to receive restorations owing to AAE; molars are most likely to receive restorations owing to tooth fracture. Dentists restored both types of NCTDs most often with RBC.     

Combining ibuprofen and acetaminophen for acute pain management after third-molar extractions: Translating clinical research to dental practice

BackgroundEffective and safe drug therapy for the management of acute postoperative pain has relied on orally administered analgesics such as ibuprofen, naproxen and acetaminophen, or N-acetyl-p-aminophenol (APAP), as well as combination formulations containing opioids such as hydrocodone with APAP. The combination of ibuprofen and APAP has been advocated in the last few years as an alternative therapy for postoperative pain management. The authors conducted a critical analysis to evaluate the scientific evidence for using the ibuprofen-APAP combination and propose clinical treatment recommendations for its use in managing acute postoperative pain in dentistry.Types of Studies ReviewedThe authors used quantitative evidence-based reviews published by the Cochrane Collaboration to determine the relative analgesic efficacy and safety of combining ibuprofen and APAP. They found additional articles by searching the Ovid MEDLINE, PubMed and http://ClinicalTrials.gov databases.ConclusionsThe results of the quantitative systematic reviews indicated that the ibuprofen-APAP combination may be a more effective analgesic, with fewer untoward effects, than are many of the currently available opioid-containing formulations. In addition, the authors found several randomized controlled trials that also indicated that the ibuprofen-APAP combination provided greater pain relief than did ibuprofen or APAP alone after third-molar extractions. The adverse effects associated with the combination were similar to those of the individual component drugs.Practical ImplicationsCombining ibuprofen with APAP provides dentists with an additional therapeutic strategy for managing acute postoperative dental pain. This combination has been reported to provide greater analgesia without significantly increasing the adverse effects that often are associated with opioid-containing analgesic combinations. When making stepwise recommendations for the management of acute postoperative dental pain, dentists should consider including ibuprofen-APAP combination therapy.
