PMID: 33742643

Septic arthritis (SA) occurrence for temporomandibular joint (TMJ) is rare. Pain, fever, swelling or loss of TMJ function are the typical presentation. The more common diagnosis for these presentations is internal derangement, osteoarthritis and rheumatoid arthritis. Therefore, TMJ septic arthritis is a challenging diagnosis and at risk of delayed diagnosis. We present a case of TMJ septic arthritis in a 46 year old Malay female with underlying hypertension and hypercholestrolemia, which was diagnosed as internal derangement in the initial presentation. The initial radiograph was normal. Arthrocentesis procedure had temporarily relieved the symptoms before progressive facial swelling developed after a week. Contrast enhanced computed tomography (CECT) brain revealed left TMJ abscess formation with left condylar erosion. Patient subsequently improved after wound debridement, left condylectomy and antimicrobial therapy.

PMID: 25803868 DOI: 10.1371/journal.pone.0121682

INTRODUCTION: Proper imaging allows practitioners to evaluate an asymptomatic tempormandibular joint (TMJ) for potential degenerative changes prior to surgical and orthodontic treatment. The recently developed cone-beam computed tomography (CBCT) allows measurement of TMJ bony structures with high accuracy. A study was undertaken to determine the morphology, and its variations, of the mandibular condyle and glenoid fossa among Malay and Chinese Malaysians.
METHODS: CBCT was used to assess 200 joints in 100 subjects (mean age, 30.5 years). i-CAT CBCT software and The Mimics 16.0 software were employed to measure the volume, metrical size, position of each condyle sample and the thickness of the roof of the glenoid fossa (RGF).
RESULTS: No significant gender differences were noted in thickness of the RGF and condylar length; however condylar volume, width, height and the joint spaces were significantly greater among males. With regards to comparison of both TMJs, the means of condylar volume, width and length of the right TMJ were significantly higher, while the means of the left condylar height and thickness of RGF were higher. When comparing the condylar measurements and the thickness of RGF between the two ethnic groups, we found no significant difference for all measurements with exception of condylar height, which is higher among Chinese.
CONCLUSION: The similarity in measurements for Malays and Chinese may be due to their common origin. This information can be clinically useful in establishing the diagnostic criteria for condylar volume, metrical size, and position in the Malaysian East Asians population.

Knowledge, perceptions and clinical application of the shortened dental arch concept among Malaysian government dentists

Kasim SKM, Razak IA, Yusof ZYM

Int Dent J, 2018 Feb;68(1):31-38.
PMID: 28782099 DOI: 10.1111/idj.12325

AIM: To assess the knowledge and perceptions of Malaysian government dentists regarding the shortened dental arch (SDA) concept and its application in clinical practice.
BACKGROUND: The SDA concept refers to a specific type of dentition with intact anterior teeth and a reduction in posterior occlusal pairs. Dentists' knowledge and perceptions of the SDA concept can influence its application in clinical practice.
METHODS: A self-administered questionnaire on the SDA concept was distributed to 326 government dentists in the states of Selangor and Kuala Lumpur, Malaysia. The data were analysed using SPSS version 22 software.
RESULTS: The response rate was 84.0%. The majority of respondents had good knowledge on five of six knowledge items and good attitudes towards 10 of 17 perception items. However, only one-fifth (20.4%) reported having applied the SDA concept in the clinic. A larger number of participants who graduated locally than who graduated abroad perceived that patients <60 years of age, without molar support, can attain acceptable chewing function and that SDA treatment does not lead to loss of occlusal vertical dimension (P < 0.05). A larger number of participants with ≤5 years of work experience than with >5 years of work experience perceived that the SDA concept enables simpler treatment planning (P < 0.05). Finally, a larger number of participants who graduated abroad than who graduated locally observed that patients without molar support had temporomandibular joint problems (P < 0.05).
CONCLUSION: Although Malaysian government dentists have good knowledge and perceptions of the SDA concept, it is not widely applied in the clinic. Concerted efforts in SDA training of dentists are needed to help to shorten denture waiting lists and reduce costs.

This study was conducted on Royal Malaysian Navy submariners who were having training in France. It was designed to compare the oral health experiences and practices while under water and on land. Methods Eightysix Royal Malaysian Navy (RMN) submariners, who had undergone at least one cycle (288 hours) of under water training, were selected to participate in a self-administered questionnaire survey. Results Seven percent of the respondents reported oro-facial pain and discomfort; 9.3% reported bleeding gums and 12.8% experienced halitosis while under water. Of those experience oral problems, 82% reported disruption of their daily activities while under water. The study showed that 82.5% of them brush their teeth at least twice a day and 94.2% rinse after meals when there were under water. Meanwhile studies on land showed that 90.7% of them brush their teeth at least twice a day and 96.5% rinse after meals. Flossing was not practiced by most of the respondents. Conclusion It is concluded that brushing and rinsing are practiced regularly by submariners regardless whether they are on land or under water but flossing is not a common practice both on land and under water. Dental emergencies, such as toothache, TMJ pain and discomfort do occur during submarine operations and disrupt their daily activities. This might poses a threat to submarine operations.

Fulltext Preventive orthodontic approach for functional mandibular shift in early mixed dentition: A case report

Sharma DS, Srivastava S, Tandon S

J Oral Biol Craniofac Res, 2018 05 03;9(2):209-214.
PMID: 31211038 DOI: 10.1016/j.jobcr.2018.05.004

The case reported here highlights the importance of examination of functional occlusion along with static occlusion. Any undetected malocclusion during early mixed dentition has potency to alter the growth and function of stomatognathic system. Premature contacts in primary canine region is the most prevalent cause of functional mandibular shift and can lead to TMJ problems for the prevalence of self correction of such malocclusion is very low if not intervened. A case of functional mandibular shift due to faulty canine guidance because of premature contacts is discussed here. Selective grinding of premature contacts and myofunctional exercise resulted in well balanced centric occlusion coinciding with centric relation.

Background: The high prevalence and impacts of orofacial pain (OFP) have caused major sufferings to individuals and society. The purpose of the study was to investigate the problems and impacts of OFP among a group of Malaysian aborigines. The objectives were to determine (i) the prevalence, aetiology, duration, severity, types and persistence of OFP during the past 3 months preceding the study; (ii) its associated impact on daily performance; and (iii) the measures taken for pain relief.
Methods: This is a cross sectional study carried out in Kuala Lipis, Pahang involving 6 villages of Orang Asli Bateq and Semai. Study sample was chosen using convenient sampling including adults aged 16 years and above. Participants were invited for an interview using structured questionnaire followed by clinical examination. Data analysis was carried out using SPSS ver12.
Results: Response rate was low at 20% (n = 140). Over one-quarter (26.4%) of the sample experienced OFP in the previous 3 months. Toothache was found to be the main aetiology (83.3%) followed by gingival pain (18.9%), temporomandibular joint (10.8%) and facial pain (8.1%). Mean duration of pain was 9.8 days for toothache, 162.4 days for gingival pain, 7.3 days for TMJ and 5.7 days for facial pain. Of those who had OFP, over half rated the pain as moderate (37.8%) and severe (29.7%) and most of the pain was ‘intermittent’ in nature (81.1%). Over half (62.2%) admitted the pain had disappeared during the interview. In terms of pain relief, 56.8% of the sample used traditional medicine. The pain had impacted on the chewing ability (70.3%, p=0.01), ability to sleep at night (73.0%, p<0.001), levels of anxiety (70.3%), ability to perform daily chores (33.3%) and social life (35.1%) of the Orang Asli sample.
Conclusion: This study suggests the prevalence of OFP was high among the Orang Asli sample, which imposed considerable physical and psychological impacts on daily life.
