Arthrocentesis versus occlusal coverage splints in the management of disc displacement without reduction: a systematic review and meta-analysis

Disc displacement without reduction (DDwoR) can cause pain and limitations in mouth opening, with a significant impact on function. The optimal management strategy for DDwoR is unclear. Treatments include conservative management such as mandibular manipulation, occlusal splints, and patient education/self-management, as well as arthrocentesis, which is a minimally invasive procedure. The aim of this systematic review and meta-analysis was to ascertain whether there is a role for arthrocentesis in the management of DDwoR. Studies analysing the outcomes pain and maximum mouth opening (MMO) in patients with DDwoR treated by arthrocentesis or occlusal coverage devices were eligible for inclusion. Following a database search, six studies with a total of 343 participants were found to be eligible for analysis (three prospective observational studies, one retrospective observational study, one non-randomized single-blind clinical trial, and one unblinded randomized clinical trial). When compared to occlusal coverage splints, arthrocentesis demonstrated a slight improvement in pain, although this was statistically non-significant (standardized mean difference (SMD) -0.50, 95% confidence interval (CI) -1.04 to 0.05, P = 0.07; I2 = 81%), and a significant improvement in MMO (SMD 0.79 mm, 95% CI 0.24-1.35 mm, P = 0.005; I2 = 79%). However, due to the significant heterogeneity between studies and the high risk of bias, along with the paucity of double-blind randomized controlled clinical trials, definitive conclusions cannot be drawn for this clinical question.

Awareness of patient’s orthodontic problems and referral practices among general dental practitioners and non-orthodontic specialists

Background/Aim. Dentists and particularly general dental practitioners (GDPs) should be able to identify problems such as malocclusions and refer patients with such problems to orthodontics. The aim of the study was to evaluate the awareness of orthodontic problems and referral practices among GDPs and non-orthodontic specialists practicing in the Kingdom of Saudi Arabia. Methods. A cross-sectional prospective study included GDP and specialists/consultants of both genders, aged between 22?60 years, practicing general dentistry and specialists other than orthodontics who had worked in their field for two or more years. Non-practicing dentists and nonregistered dentists were excluded. Data was analyzed on SPSS version 21.00. Results. Among the respondents, 55.5% were men, and 44% were GDPs. Out of the total number of respondents, 107 (53.5%) GDPs and 66 (33%) non-orthodontic specialists practiced orthodontic referral in their practices. By using the ?2 test, statistical analysis of different variables depending on the participants? gender and specialty was performed. It revealed that variables with significant p-value were: orthodontist referral, the recommendation of orthodontic treatment only after the eruption of all permanent teeth, awareness of tooth extraction for alignment of irregular teeth, and awareness regarding worsening of temporomandibular joint problems by orthodontic treatment. Conclusion. The referral practices of dentists practicing in the Kingdom of Saudi Arabia concerning orthodontic patients were satisfactory, although awareness regarding orthodontic problems requires continuous learning and considerate positive progression toward basic orthodontics.

Role of teledentistry in paediatric dentistry

Introduction As a result of the COVID-19 pandemic, teledentistry has been used more frequently due to social distancing regulations to minimise the need for face-to-face attendances. Aims Evaluate uses of teledentistry within Newcastle Dental Hospital's Paediatric Dentistry New Patient Service. Establishes potential roles of teledentistry within paediatric dentistry and advantages and disadvantages of this service method. Methods Service evaluation of 653 new patient teledentistry appointments at Newcastle Dental Hospital across a one-month period (13 May- 12 June 2020).Discussion By implementing a telephone consultation as the first point of contact with our team, we were able to reduce the number of face-to-face appointments required by over a third. Teledentistry can be used for numerous applications within paediatric dentistry including initial triage, remote assessment, reinforcement of prevention, implementing initial management and building rapport. Conclusion Teledentistry is an emerging field and has the potential to improve patient journeys, reduce waiting lists and reduce unnecessary face-to-face attendances which is especially important both within and beyond the current COVID-19 pandemic to maximise safety and minimise inconvenience for both parent and child. However, care must be taken to ensure a clinician is confident in their diagnosis prior to discharging or delaying management of a patient.

The effect of the ischaemic compression technique on pain and functionality in temporomandibular disorders: A randomised clinical trial

BACKGROUND

Interventions addressing pain and impaired functionality in individuals with temporomandibular disorders (TMDs) are needed.

OBJECTIVE

To compare the effects of 4 weeks of exercise combined with ischaemic compression and exercise alone in patients with TMDs.

METHODS

Fifty patients who were diagnosed with TMDs were randomised into Group 1 (exercise combined with ischaemic compression technique) (n = 25) or Group 2 (exercise alone) (n = 25). Both groups performed 4 weeks of Rocabado's exercise and 3 weeks of postural exercise, while Group 1 received ischaemic compression to the masseter muscle for a total of 3 sessions in addition to exercise. A ruler was used to assess range of motion (ROM) (painless mouth opening (PMO), maximum mouth opening, maximum assisted mouth opening (MAMO), left lateral movement and right lateral movement), the visual analogue scale and graded chronic pain scale were used to assess pain, an algometer was used to determine the pain pressure threshold (PPT), and the 8-item jaw functional limitation scale was used to assess, functionality. The assessments were performed at baseline, at week 1 and at week 4.

RESULTS

The participants in Group 1 exhibited larger PMO (F = 5.26, P = .02) and MAMO values (F = 6.71, P = .01) than did the patients in Group 2 at week 1. The effect size was small for MAMO (ES = 0.27) and moderate for PMO (ES = 0.51). However, there were no significant differences in any other outcomes between groups at week 1 or 4.

CONCLUSION

In summary, this randomised controlled trial indicates that exercise combined with ICT and exercise alone have similar effects on ROM, pain, the PPT and functionality in patients with TMDs.

A cross-sectional study of the association between anxiety and temporomandibular disorder in Australian chiropractic students

OBJECTIVE

This study examined the association between anxiety and temporomandibular disorder (TMD) in Australian chiropractic students, particularly its effect on quality of life.

METHODS

Chiropractic students (n = 185) completed online surveys, including the Oral Health Impact Profile for TMDs (OHIP-TMD) and the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. The OHIP-TMD psychometric properties were assessed using principal component analysis. Linear regression models were used to examine demographic predictors for anxiety and TMD. A general linear model assessed the association between anxiety and the psychosocial and function scales identified through analysis of the OHIP-TMD questionnaire.

RESULTS

The mean value for the OHIP-TMD and PROMIS was 1.3 (SD = 0.7) and 9.5 (SD = 4.1), respectively. Women reported significantly lower quality of life (QoL) related to TMD symptoms (p = 0.006) and that QoL related to TMD symptoms increased significantly as students progressed through the course (p = .025). Lower levels of anxiety were significantly associated with male gender (p = .000), employment (p = .008), higher program levels (p = .003), and having children (p = .005). General linear model analysis revealed that increased anxiety was significantly associated with higher levels of oral physical function impairment (p = .003) and elevated psychosocial distress (p = .0001).

CONCLUSION

Anxiety was significantly associated with psychosocial distress and oral physical function impairment in university chiropractic students. In addition to impacting on oral health-related QoL, anxiety also affects students' engagement with learning and academic performance. It would therefore be beneficial to implement strategies that mitigate students' anxiety levels.

Clinical efficacy of a simplified approach to managing chronic temporomandibular disorders: evidence from a 1-year case series

OBJECTIVE

Chronic temporomandibular disorder (cTMD) produces orofacial pain and limited jaw function and impacts on quality of life. A clinical case series of patients referred to a hospital specialist service is described here.

STUDY DESIGN

In a 1-year consecutive case series of 162 patients with cTMDs, each patient had been managed with self-awareness and jaw exercises, as well as oral appliances. Pain severity and chewing function were scored by using a visual analogue scale (VAS), and quality of life was assessed by using the Oral Health Impact Profile-Temporomandibular Dysfunction (OHIP-TMD).

RESULTS

Females comprised 87% (average age 49 years). Treatment time averaged 20.8 months, and the average pain duration was 2.8 years. The mean VAS pain score fell from 6.9 (standard deviation [SD] 1.6) to 2.0 (SD 1.9) after treatment, giving a "large" effect size of 3.1. Chewing difficulty improvement also showed a "large" effect size (2.5). For the 33 patients for whom longitudinal OHIP-TMD data were available, the mean pretreatment and posttreatment scores of 51.2 (SD 20.9) and 26.2 (SD 17.7) showed a "large" effect size of 1.2.

CONCLUSIONS

A simple noninvasive protocol for managing cTMD with self-help, exercises, and oral devices resulted in clinically and statistically meaningful improvements in pain, function, and quality of life.
