Objective: To investigate the possible changes in the mechanical properties of the orofacial and neck muscles in patients with temporomandibular disorders (TMD). Methods: The study included a total of 98 females. Females were divided into three groups as myogenous TMD, mixed TMD, and healthy controls. The frequency (indicator of muscle tone), stiffness, and decrement (related to muscle elasticity) values of the sternocleidomastoid, upper trapezius, cervical extensor, and masseter muscles were measured using a portable myotonometer. Results: The frequency, stiffness, and decrement values of the masseter muscle were higher in the mixed and myogenous TMD groups than those of the control group (p < 0.017). The mixed TMD group had higher frequency and stiffness values in the upper trapezius muscle compared with the control group (p < 0.017). Discussion: The results suggest that the mechanical properties of the oral and neck muscles may be affected in patients with TMD.

Fibrous Dysplasia (FD) is a developmental disorder of bone that can affect one bone (monostotic type) or multiple bones (polyostotic type). The disease can be associated with hyperpigmentation and endocrinological disorders. In general, FD is found in teenagers, in the second decade of life. It often involves the long bones, craniofacial bones, ribs and pelvis. Approximately 30% of monostotic FD (MFD) lesions are found in the cranial, rather facial bones. It frequently appears in the posterior region of the jaw bone and is usually unilateral. The etiology of FD is not clear but even so genetic predisposition is suspected. The diagnosis is based on radiological and histopathological examination. We present an unusual case of symptomatic FD. A 15-year-old female patient was admitted to the clinic, complaining gradually increased swelling on her left side of the mandible one year ego with severe and unusual pain at related region. The bony enlargement was extending from median mandible to the crestal marginal level. Surgical shaving and recountering of mandible through the delicate preservation of the mental nerve in the left side of mandible was carried out. The aim of this report is to present the conservative treatment as sufficient treatment modality for the treatment of FD during puberty. doi: https://doi.org/10.12669/pjms.35.3.14 How to cite this:Kaynak BA.

Background. Changes in the fatty infiltration and/or muscle volume of neck muscles can alter cervical spine alignment and cranial load distribution, which may cause pain in the orofacial region. Objectives. The aim of the study was to examine the muscle volume and fatty infiltration of neck muscles in patients with temporomandibular disorders (TMD). Material and methods. This case-control study included 18 patients with TMD and 18 age- and sex-matched controls. The muscle volume and fatty infiltration of the neck muscles of the participants were measured using magnetic resonance imaging (MRI) and ITK-SNAP software. The 3D models of the sternocleidomastoid (SCM), splenius capitis (SPLC), semispinalis cervicis (SC)-semispinalis capitis (SCP), and multifidus (M) muscles within the C3-C7 range were created using ITK-SNAP, a semi-automatic segmentation software. The models were used to determine the volumes and fatty infiltration levels. The Neck Disability Index (NDI) was used to assess neck pain-related disability. The severity of TMD was determined using the Fonseca Anamnestic Index (FAI), while jaw-related disability was measured with the Jaw Functional Limitation Scale-20 (JFLS-20). Pain levels were recorded at rest and during chewing using the numeric rating scale (NRS). Results. There were no statistically significant differences in total muscle volume, fatty infiltration volume and fatty infiltration percentage of the SCM, SPLC, SCP, SC, and M muscles between the 2 groups (p > 0.05). The patient group had higher NDI scores compared to the controls (p < 0.001). The NDI scores correlated positively with the JFLS-20 (r = 0.831, p < 0.001), FAI (r = 0.815, p < 0.001) and NRS scores at rest (r = 0.753, p < 0.001) and during chewing (r = 0.686, p < 0.001). Conclusions. The present study did not identify any significant differences in the neck muscle volume or fatty infiltration between the TMD patients and controls. However, the severity of neck disability was found to correlate with jaw function, pain and TMD levels.

Objective: The purpose of this study was to investigate the aerobic capacity in patients with temporomandibular dysfunction (TMD) and to compare the results with those of the asymptomatic individuals. Methods: The TMD group included a total of 31 females between the ages of 18 and 25 years. The control group consisted of 31 asymptomatic females with an age range of 18 to 27 years. A graded exercise test was performed using an electronically braked arm crank ergometer. An indirect calorimeter system was used to calculate the peak oxygen consumption (VO₂peak). In addition, peak heart rate (HR_peak) and respiratory quotient were calculated for each participant. Results: The TMD group had lower VO₂peak (p = 0.017) and HRpeak (p = 0.012) in aerobic capacity tests; however, respiratory quotient was similar in both groups (p = 0.446). Discussion: The TMD group had lower aerobic capacity compared to the asymptomatic individuals.

Amaç: Bu çalışmanın amacı, üniversite öğrencilerinde temporomandibular eklem disfonksiyonu (TMED) prevalansının araştırılmasıdır. Gereç ve Yöntem: Bu çalışma, 18-25 yaş aralığında (20,5±1,5 yıl) 1104 kadın ve 334 erkek olmak üzere 1438 üniversite öğrencisinin katılımıyla gerçekleşti. Çalışmaya katılan bireylerde TMED varlığı, Fonseca Anamnestik Anketi kullanılarak değerlendirildi. Fonseca Anamnestik Anketi 10 sorudan oluşmaktadır. Katılımcıdan her soruya ‘Evet’ (10 puan), ‘Hayır’ (0 puan) ve ‘Bazen’ (5 puan) olmak üzere cevap vermesi istenir. Anket sonucunda elde edilen skora göre bireyler TMED yok (0-15 puan), hafif TMED’li (20-40 puan), orta şiddette TMED’li (45-65 puan) ve şiddetli TMED’li (70-100) olarak sınıflandırıldı. Bulgular: Değerlendirilen 1438 bireyden 547’sinde (%38) TMED olmadığı bulunurken, bireylerin 891’inde (%62) TMED olduğu tespit edildi. TMED’li bireylerde TMED şiddeti incelendiğinde, TMED tespit edilen 891 bireyden 664’ünde (%46,2) hafif şiddette TMED, 180’ında orta şiddette TMED (%12,5) ve 47’sinde (%3,3) şiddetli TMED olduğu bulundu. Değerlendirilen 1104 kadın bireyden 730’unda (%66,1) TMED tespit edilirken, 374 kadın bireyde (%33,9) TMED olmadığı bulundu. Değerlendirilen 334 erkek bireyden 173’ünde (%51,3) TMED yok iken, 161 erkek bireyde (%48,7) TMED olduğu bulundu. Sonuç: Elde edilen sonuçlar üniversite öğrencilerinde TMED prevalasının %62 olduğunu göstermektedir. Ayrıca, TMED’li bireylerin önemli bir kısmının hafif TMED’li bireylerden oluştuğu tespit edildi. Kadınlarda TMED prevalansının ve şiddetinin erkeklere göre daha fazla olduğu bulundu.
