RESUMEN
BACKGROUND: Large horizontal maxillary overjet (overjet) is associated with reduced bite force (BF) and number of contacts, which influence the chewing effectivity (CE). Oral health, oro-facial function (OF) and malocclusion have great impact on psychological well-being and quality of life (QoL). OBJECTIVES: The aims of the study were to examine OF, temporomandibular disorders (TMD), BF, CE, QoL and well-being in children and adolescents with large overjet. METHODS: The study was a case-control study including healthy children with large overjet in the study group compared to a control group of healthy children with neutral occlusion, all 9-14 years old. OF was examined by use of Nordic Orofacial Test-Screening (NOT-S), Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and registration of morphological and functional occlusion. QoL and well-being were examined using KIDSCREEN-10 and Strengths and Difficulties Questionnaire. RESULTS: The study and control groups included 37 and 32 participants, respectively. Significantly increased NOT-S score (p < .001) and reduced BF (p = .011), numbers of contacts (p < .001) and CE (p = .005) were found in the study group. BF, numbers of contacts and CE were negatively associated with erupting canines and premolars. No significant difference was found in age, gender, dental eruption, TMD diagnosis or QoL between the groups. Significantly increased emotional symptoms (p = .007), hyperactivity (p = .043) and total difficulties score (p = .009) were found in the study group. CONCLUSION: The study group showed higher NOT-S score and reduced BF, number of contacts and CE. No difference in QoL were found between the groups, although reduced well-being and increased emotional symptoms, hyperactivity and total difficulties were found in the study group.

BACKGROUND: The difficulties and challenges faced by people with Parkinson's disease (PD) in performing daily orofacial function are not systematically investigated. In this study, specific orofacial non-motor and motor symptoms and functions were systematically examined in PD patients in comparison to a matched control group. METHODS: The clinical case-controlled study was conducted from May 2021 to October 2022 and included persons with PD and age- and gender-matched persons without PD. The participants with PD were outpatients diagnosed with PD at the Department of Neurology at Bispebjerg University Hospital in Copenhagen, Denmark. The participants underwent a systematic clinical and relevant self-assessment of the orofacial function and temporomandibular disorders (TMD). The primary outcomes were objective and subjective assessments of the general orofacial function, mastication, swallowing, xerostomia and drooling. The secondary outcomes were the prevalence of TMD and orofacial pain. The difference in outcome measures between the two groups was analysed using chi-square and Mann-Whitney U test. RESULTS: The study included 20 persons with PD and 20 age- and gender-matched persons without PD. Both objectively and subjectively, persons with PD had poorer orofacial function than the control group. Persons with PD had also a significantly more severe limitation of jaw mobility and jaw function. The objective masticatory function was also significantly reduced for persons with PD compared to the control group, and 60% of persons with PD found it difficult to eat foods with certain consistencies while 0% of the control group reported that problem. Persons with PD could swallow less water per second and the average swallowing event was significantly longer for PD persons. Even though PD persons reported more xerostomia (58% for persons with PD and 20% for control persons), they also reported significantly more drooling than the control group. Additionally, orofacial pain was more prevalent in PD persons. CONCLUSIONS: Persons with PD have a compromised orofacial function. Furthermore, the study indicates a link between PD and orofacial pain. In order to screen and treat persons with PD accordingly, healthcare professionals should be aware of and address these limitations and symptoms. TRIAL REGISTRATION: The trial was approved by the Regional Committee on Research Health Ethics of the Capital Region (H-20,047,464), the Danish Data Protection Agency (514 - 0510/20-3000), and registered at ClinicalTrials.gov (NCT05356845).

BACKGROUND: Parkinson's disease (PD) has a negative effect on oral health and orofacial function, but the subjective experience of orofacial symptoms and their impact on the quality of life is not fully investigated. In addition, knowledge of how to improve the subjective oral symptoms is lacking. OBJECTIVES: To assess the self-reported orofacial function and oral health in patients with PD. Furthermore, to investigate the effect of interventions for improvement of oral hygiene and function on oral health-related quality of life (OHRQoL). METHODS: A randomised controlled study with delayed intervention was conducted in 29 patients with moderate to advanced PD. Patients were instructed in a standardised exercise programme for the jaw and orofacial muscles and given an individualised oral hygiene programme. The effect on self-reported orofacial function and OHRQoL was measured after 2 and 4 months using the Nordic Orofacial Test-Screening (NOT-S), the oral health impact profile (OHIP-14), self-reported drooling score and subjective mastication ability. RESULTS: Self-reported oral health and function before the intervention was significantly correlated to the severity and duration of PD. The NOT-S and drooling score were significantly improved by the interventions after 2 months and the OHIP-14 after 4 months. CONCLUSION: The interventions improve the self-reported orofacial function and OHRQoL. These simple interventions can be implemented in the allied multidisciplinary health care surrounding the PD patient.

BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disorder. It is associated with reduced oral health and impaired oro-facial function, but besides recommendations of dental visits and drooling treatment, there are little documented odontological treatment options. OBJECTIVES: To evaluate the effect of standardised home exercise jaw opening and chewing programmes, as well as home oral hygiene measures instructed and controlled by a trained dentist. METHODS: Twenty-nine patients (median 65 years) with moderate to advanced PD participated in the project after informed consent. They were followed at a Neurology Department, were able to cooperate, and had stable medical treatment and nine also deep brain stimulation. The interventions were individual dental hygiene instruction, training of jaw opening (JawTrainer), and lip and chewing exercises (Ulmer Oral Screen and Proxident Fluoride Gum). The study was performed as a randomised controlled study. The treatment effect was evaluated after 2 and 4 months. The primary outcome was maximum unassisted jaw opening capacity, chewing time of a standardised apple slice, and the Simplified Debris Index. Results were analysed with Wilcoxon matched pairs test and Mann-Whitney U test (significance level P < .05). RESULTS: Jaw opening, chewing time and hygiene were significantly improved 2 months from the start of the invention, respectively, 6%, 49%, and 25%, and the improvement was still significant after 4 months. No significant changes were found after the 2-month control period without intervention. CONCLUSION: The simple measures had a substantial and significant clinical effect which is promising despite the progressive nature of the PD.

BACKGROUND: Oromandibular dystonia (OMD) with involuntary jaw and tongue movements may be misdiagnosed as temporomandibular disorders (TMD) and because of the complex muscle activity and involvement of several small muscles, OMD is also considered difficult to treat. OBJECTIVES: The aim was to evaluate OMD in patients 8-10 years after start of treatment with botulinum toxin (BoNT) by self-reported and standardised global scales and questionnaires. METHODS: Of 21 previously reported patients with OMD, 14 responded to a mail health questionnaire to describe the disease course and treatment effect as well as the overall impact of OMD by a visual analogue scale (VAS), the Patient Health Questionnaire (PHQ) for depression and anxiety, and the Jaw Functional Limitation Scale (JFLS). The results were analysed with non-parametric statistical analysis (Wilcoxon matched-pairs test and Spearman's rank-order correlations). RESULTS: The OMD was still present in 13 patients. In nine patients, the BoNT treatment had continued as monotherapy or combined with oral medication. VAS for OMD was significantly reduced (P < 0.04) over the years, and most patients felt improvement from the treatment. However, the patients had still some functional limitations, typically regarding jaw mobility and communication, and both JFLS and mental distress (PHQ) were significantly correlated with the OMD VAS (rS 0.77 and 0.74). CONCLUSION: The results showed marked reduction of the experienced OMD with treatment and over time, and also stressed similarities between OMD and TMD. Both dentists and neurologists should be aware of this overlap and reduce misdiagnosis by applying an interdisciplinary approach.

OBJECTIVE: The Nordic Orofacial Test-Screening (NOT-S) was developed as a comprehensive method to assess orofacial function. Results from the screening protocol have been presented in 11 international publications to date. This study reviewed these publications in order to compile NOT-S screening data and create profiles of orofacial dysfunction that characterize various age groups and disorders. MATERIALS AND METHODS: NOT-S results of nine reports meeting the inclusion criteria were reviewed. Seven of these studies not only provided data on the mean and range of total NOT-S scores, but also on the most common domains of orofacial dysfunction (highest rate of individuals with dysfunction scores), allowing the construction of orofacial dysfunction profiles based on the prevalence of dysfunction in each domain of NOT-S. RESULTS: The compiled data comprised 669 individuals, which included healthy control subjects (n = 333) and various patient groups (n = 336). All studies reported differences between individuals with diagnosed disorders and healthy control subjects. The NOT-S data could measure treatment effects and provided dysfunction profiles characterizing the patterns of orofacial dysfunction in various diagnoses. CONCLUSIONS: This review corroborates previous results that the NOT-S differentiates well between patients and healthy controls and can also show changes in individuals after treatment. NOT-S could be used as a standard instrument to assess orofacial dysfunction, evaluate the outcomes of oral habilitation and rehabilitation and improve comparability in clinical practice and research.

STUDY OBJECTIVES: The aim of the study was to examine the prevalence of sleep-disordered breathing (SDB) in children and adolescents with large overjet due to mandibular retrognathia compared to a control group. METHODS: In this case-control study children with large overjet ≥ 6 mm due to mandibular retrognathia (study group) were compared to a group with neutral occlusion (controls). All participants underwent respiratory polygraphy (PG) and questionnaires regarding sleepiness and snoring. Differences across groups were tested by: Chi-square, general linear model adjusted for age, sex, and body mass index (BMI), and Mann-Whitney test. Differences in results of PG were also tested by general linear model adjusted for age, sex, and BMI according to severity of mandibular retrognathia. RESULTS: Thirty-seven (19 male;18 female, median age 12.3 years) participants were included in the study group and 32 (16 male;16 female, median age 12.2 years) in the control group. No significant difference in SDB assessed by PG or questionnaires between the groups was found even though the snore index was higher in the study group (p=0.051). The snore index was higher than the parent-reported snoring. Respiration rate was significantly reduced in the study group (p=0.043), and estimated sleep time efficiency was significantly reduced in males compared to females (p<0.001). CONCLUSIONS: No significant differences in SDB were found between the groups even though the snore index was higher in the study group. The snore index of the PG was higher than the parent-reported snoring. Estimated sleep time efficiency was reduced in males. The study improves the understanding of risk of SDB in non-obese children with large overjet due to mandibular retrognathia and may contribute to an interdisciplinary approach of risk assessment of SDB in children with malocclusion. CLINICAL TRIAL REGISTRATION: NCT04964830.
RESUMEN
The aim of this study was to compare the assessment of tooth wear performed on digital models with the one conducted at the clinical examination. Seventy-eight volunteers (29 males and 49 females, age range 20-30 years) with at least 24 teeth, normal oral function, and a neutral transverse relationship were examined. During the clinical examination, dental wear was registered according to the Basic Erosive Wear Examination (BEWE) index. Subsequently, the BEWE index was blindly applied by two examiners on digital models obtained from the volunteers. Data were analyzed using weighted Cohen's kappa coefficient and correlation tests with a confidence interval of 95%. All volunteers showed signs of tooth wear. Anterior teeth showed increased severity of tooth wear than first molars. Early loss of tooth substance could be identified on the digital models, including in areas with challenging direct intraoral visual access. Approximately 50% of the scores based on clinical examination agreed with those based on examination of digital models (k = 0.543, p < 0.01). A moderate, positive correlation was observed between scores registered clinically and on digital models (Spearman's rho = 0.560, p < 0.001). Considering the rather low agreement between the clinical and digital scores, alternatives to using BEWE on digital models are needed.

OBJECTIVES: Persons with Parkinson's disease (PD) have a higher prevalence of oral diseases and orofacial dysfunction, but knowledge about the use of dental care and whether their dental care needs are met is sparse. This study aimed to investigate the dental attendance and usage of dental care services of the total PD population in Denmark and compare it with a control group. METHODS: National registers were used to identify the total PD population in Denmark (n = 6874) and to obtain data on their dental care from 2015 to 2019. These data were compared with a five-fold age-, gender- and geographically matched control group without PD (n = 34 285). Register data on age, gender, civil status, educational level, income, nursing homes status and mortality were also collected and adjusted for in the analyses. The dental attendance was analysed using χ2 -test with Bonferroni correction, and the type of dental care services was analysed using negative binomial regression analysis. RESULTS: A significantly higher proportion of persons with PD were irregular attenders of the dental care system (21.0%), compared with the control group (16.9%). Persons with PD had a significantly higher overall usage of dental cares services. Most prominent was the high usage of treatment services, where persons with PD had a 1.50 times higher incidence rate of tooth extractions and a 1.71 times higher incidence rate of tooth fillings in the five years compared with the control group. CONCLUSION: Persons with PD are more often irregular users of dental care and receive more treatment services than the control group. This indicates a need for high-quality prophylactic initiatives to prevent high filling and tooth extraction rates. Furthermore, this knowledge can be used by clinicians and decision makers to ensure optimal dental care for persons with PD.

BACKGROUND: Progressive weakness can affect bulbar muscles in individuals with moderate to severe forms of spinal muscular atrophy (SMA). The paucity of standardized, valid bulbar assessments capturing clinically significant deficits in SMA impedes the ability to monitor function, facilitate intervention, or detect treatment response. OBJECTIVE: To fill this void, an international multidisciplinary team gathered to develop an agreed upon consensus-derived assessment of bulbar function in SMA for inter-professional administration to enhance our ability to monitor disease progression, support clinical management, and evaluate treatment effects. METHODS: Fifty-six international clinicians experienced in SMA were invited and engaged using the Delphi method over multiple rounds of web-based surveys to establish consensus. RESULTS: Serial virtual meetings occurred with 42 clinicians (21 speech and language therapists, 11 physical therapists, 5 neurologists, 4 occupational therapists, and 1 dentist). Seventy-two validated assessments of bulbar function were identified for potential relevance to individuals with SMA (32 accessible objective, 11 inaccessible objective, 29 patient-reported outcomes). Delphi survey rounds (nâ=â11, 15, 15) achieved consensus on individual items with relevance and wording discussed. Key aspects of bulbar function identified included: oral intake status, oral facial structure and motor strength, swallowing physiology, voice & speech, and fatigability. CONCLUSIONS: Multidisciplinary clinicians with expertise in bulbar function and SMA used Delphi methodology to reach consensus on assessments/items considered relevant for SMA across all age groups. Future steps include piloting the new scale moving towards validation/reliability. This work supports the advancement of assessing bulbar function in children and adults with SMA by a variety of professionals.

BACKGROUND: We performed this study to quantify the detrimental effect of intraneural injection of 50 µL of saline, articaine 2%, or articaine 4% in the rat sciatic nerve. METHODS: Lumbar-evoked electrospinograms from stimulation of the sciatic nerve were recorded before and immediately after injection and again after 3 weeks. Test substance was injected into the right sciatic nerve, and the untreated left sciatic nerve served as control. The animals were killed after the 3-week follow-up, and cross-sections of the sciatic nerve were examined stereologically. RESULTS: The evoked spinal cord field potential in the articaine groups faded away immediately after injection and was concentration-dependently, significantly more reduced at the 3-week follow-up in comparison with the saline group. The response from the control sides was unaffected in all groups. The number of myelinated axons was unaffected by the treatment. The mean cross-sectional axon area and the mean myelin sheath thickness were significantly reduced in animals injected with articaine 4%. CONCLUSIONS: These observations indicate concentration-dependent neurotoxic injuries after injection of articaine with a significant difference between 2% and 4% formulations. The mechanical injury of needle penetration with saline injection had no significant effect on nerve conduction or histomorphology.

No comprehensive study has previously been published on orofacial function in patients with well-defined Parkinson's disease (PD). Therefore, the aim of this study was to perform an overall assessment of orofacial function and oral health in patients, and to compare the findings with matched control subjects. Fifteen outpatients (nine women and six men, 61-82 yr of age; Hoehn & Yahr Stages 2-4; and with motor impairment ranging from 17 to 61 according to the Unified Parkinson's Disease Rating Scale, Objective Motor Part III) were examined in their 'on' state together with 15 age- and gender-matched controls. Orofacial function and oral health were assessed using the Nordic Orofacial Test, masticatory ability, performance and efficiency, oral stereognosis, jaw opening, jaw muscle tenderness, the Oral Health Impact Profile-49, number of natural teeth, and oral hygiene. Orofacial dysfunction was more prevalent, mastication and jaw opening poorer, and impact of oral health on daily life more negative, in patients with PD than in controls. The results indicate that mastication and orofacial function are impaired in moderate to advanced PD, and with progression of the disease both orofacial and dental problems become more marked. It is suggested that greater awareness of the special needs in PD patients and frequent dental visits are desirable to prevent dental diseases and decay and to support masticatory function.

AIM: To assess whether changes in diagnoses and management of temporomandibular joint disorder (TMJD) patients are influenced by radiographic findings and if there is an association between specific radiologic alterations and management strategy changes. METHODS: A total of 204 patients with TMJ symptoms were examined using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Diagnoses and management were first decided without the aid of radiographs. Management categories were: pharmacology, physiotherapy, counseling and behavioral treatment, occlusal stabilization, surgery, additional examinations, and referrals, each with subcategories. Sagittal TMJ tomograms were assessed for the presence of flattening, erosion, osteophyte, and sclerosis in the TMJ components. Diagnoses and management were reevaluated after gaining access to the radiographs and radiographic classifications. Logistic regression analyses were performed with changes in management as the dependent variable and age and radiographic findings as the independent variables. RESULTS: Diagnosis was changed for 56 patients, mainly from arthralgia to osteoarthritis. Management was changed for 55 patients. Most changes occurred in pharmacology and physiotherapy followed by counseling and behavioral treatment, occlusal stabilization, referrals, additional examinations, and surgery. Changes were mostly within the categories, and the highest number of changes was seen in pharmacology, physiotherapy, and counseling and behavioral treatment. Radiographic degenerative findings increased the chance of change (any change) (odds ratio [OR] â 2.03) and the chance of change in pharmacology (OR â 2.56) and physiotherapy (OR = 2.48) separately. No other significant associations were found. CONCLUSION: Radiographic degenerative findings increased the chance of changes in management strategy. However, 73% of the TMJD patients had no changes in management after radiographic examination. In cases with changes, these were mainly adjustments within management categories.

OBJECTIVE: Drooling in neurodegenerative diseases is associated with social impediment. Previous treatments of drooling have little effect or are effective but with severe side effects. Therefore, there is a need to test new methods such as the use of botulinum toxin type A (BTX-A). MATERIAL AND METHODS: This open, prospective study deals with treatment of drooling in 12 patients with amyotrophic lateral sclerosis and three with Parkinson's disease. Injections of BTX-A (Botox) were given into the parotid (25-40 units) and submandibular (15-30 units) glands with ultrasonographic guidance. After BTX-A treatment, the patients were followed for 2 months with evaluations every second week by means of self-assessed rating scales for drooling intensity, discomfort and treatment effect, and determination of unstimulated whole saliva (UWS) flow rate, and inorganic and organic UWS composition. The treatment was repeated up to four times, but seven patients dropped out shortly after the first treatment due to marked worsening of their disease-related condition. RESULTS: Drooling and flow were reduced (P < 0.05) 2 weeks after treatment, without side-effects. The maximal reductions during the observation period were 40% for drooling and 30% for flow. There was a systematic variation in flow during the observation period, with an initial decrease and then an increase followed by a second decrease. Amylase activity and total protein concentration generally increased with decreasing flow (P ≤ 0.03). CONCLUSION: Inhibition of acetylcholine release from postganglionic parasympathetic nerve endings by injection of BTX-A into salivary glands seemed useful for secondary sialorrhoea, although cyclic variations in flow may occur, possibly due to transitory sprouting and regeneration.

AIMS: To investigate the sensitivity and specificity of the TMD pain screener in a headache population. METHODS: A cross-sectional study was conducted at the Danish Headache Center (DHC). Patients were included if they had primary or secondary headache, trigeminal neuralgia, or facial pain. The pain screener was compared to the outcome of a full Diagnostic Criteria for TMD (DC/TMD) examination. RESULTS: A total of 62 headache patients were included (77% women). The sensitivity of the pain screener short version (three questions) was 85% (95% CI: 70% to 94%), and the specificity was 64% (95% CI: 41% to 83%). In the full version (six questions), the sensitivity was 83% (95% CI: 67% to 93%), and the specificity was 82% (95% CI: 60% to 95%). CONCLUSION: The TMD pain screener seems to be a valid tool to accurately screen for the presence of TMD to provide the most optimal treatment for headache patients. These findings should however be confirmed in a larger sample with migraine, tension-type headache, and trigeminal neuralgia.

BACKGROUND: No comprehensive patient-centered and clinical evaluations of the functional effect of treatment with implant-supported single crowns (ISSC) have been reported previously. OBJECTIVE: To investigate whether and how treatment with ISSC affects masticatory function and Oral Health-Related Quality of Life (OHRQoL) in subjects with tooth agenesis. MATERIAL AND METHODS: In nine females and nine males (32 + or - 10 years) with agenesis treated with one to four ISSC (68% in the premolar region), the treatment effect and masticatory function were assessed. The evaluation was performed first after implant placement shortly before crown cementation, and again 1 month after cementation. It consisted of questionnaires [including Oral Health Impact Profile (OHIP-49)] and functional examination with plastic strips, the Dental Prescale Film and the Occluzer system, Xylitol color-changeable gum and slices of Granny Smith apple. RESULTS: The patients' satisfaction with treatment was high and they experienced a significant overall improvement in their OHRQoL (on average 13% reduction in the total OHIP scores). The cementation of the crowns was associated with a significant increase in the number of near occlusal tooth contacts, contact area, bite force, and masticatory ability and performance. Correspondingly, there was a significant, positive correlation between the number of tooth contacts and (1) occlusal contact area, (2) bite force, and (3) masticatory performance. CONCLUSION: Treatment with ISSCs in subjects with tooth agenesis significantly increased masticatory function subjectively and clinically as well as OHRQoL. However, as the functional parameters before replacement of the teeth corresponded to values in subjects with complete dentitions, the functional importance of the increase may be questioned.

AIMS: To investigate whether an international consensus exists among TMD experts regarding indications, performance, follow-up, and effectiveness of jaw exercises. METHODS: A questionnaire with 31 statements regarding jaw exercises was constructed. Fourteen international experts with some geographic dispersion were asked to participate in this Delphi study, and all accepted. The experts were asked to respond to the statements according to a 5-item verbal Likert scale that ranged from "strongly agree" to "strongly disagree." The experts could also leave free-text comments, which was encouraged. After the first round, the experts received a compilation of the other experts' earlier responses. Some statements were then rephrased and divided to clarify the essence of the statement. Subsequently, the experts were then asked to answer the questionnaire (32 statements) again for the second round. Consensus was set to 80% agreement or disagreement. RESULTS: There is consensus among TMD experts that jaw exercises are effective and can be recommended to patients with myalgia in the jaw muscles, restricted mouth opening capacity due to hyperactivity in the jaw closing muscles, and disc displacement without reduction. The patients should always be instructed in an individualized jaw exercise program and also receive both verbal advice and written information about the treatment modality. CONCLUSION: This Delphi study showed that there is an international consensus among TMD experts that jaw exercises are an effective treatment and can be recommended to patients with TMD pain and disturbed jaw function.

AIM: To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings. METHODS: Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion. Logistic regression analyses were performed with the radiographic findings as the dependent variables and the following clinical variables as independent variables: opening pattern, maximal jaw opening, TMJ sounds, number of painful muscle/TMJ sites, duration of pain, presence of arthritic disease, depression and somatization scores, graded chronic pain, and age and gender. RESULTS: Coarse crepitus on opening/closing (odds ratio [OR] > or = 3.12), on lateral excursions (odds ratio > or = 4.06), and on protrusion (OR > or = 5.30) was associated with increased risk of degenerative findings in tomograms. A clinical diagnosis of osteoarthritis increased the risk of radiographic findings (OR > or = 2.95) and so did increasing age (OR > or = 1.03 per year) and the female gender (OR > or = 2.36). Maximal assisted opening and maximal opening without pain (< 40 mm) was associated with a posterior condyle-to-articular tubercle position (OR > or = 2.60). No other significant associations were observed. CONCLUSION: Age, gender, and coarse crepitus, but no pain-related variables, were associated with increased risk of degenerative findings in TMJ tomograms. Maximal opening < 40 mm was associated with a posterior condyle-to-articular tubercle relation on opening.
