English, Objectives : To investigate to what extent different types of jaw-muscle contractions cause haemodynamic reactions in human masseter muscle. Materials and Methods : Eleven healthy volunteers (seven males : 25.0±2.9 years and four females: 23.3±4.3 years) performed three standardized oral-motor tasks : maximal voluntary contractions (MVC ; duration 5 sec, 3 times repetition), tooth grinding (repetitive left and right side grinding from intercuspal position to canine-to-canine position at 0.5 Hz keeping 50% MVC for a total of 10 times), and 1-min left-side gum chewing at 1 Hz. Haemodynamic characteristics were measured in the left masseter muscle with the use of a laser blood oxygenation monitor (BOML1TRW, OMEGAWAVE INC., Tokyo, Japan). Electromyographic (EMG) activity from right and left masseter muscle was simultaneously monitored (500 Hz sample frequency) during the tasks. 1-ANOVA followed by Dunnett's test was used. Results : Oxygenated haemoglobin (OXYHb : 13.5±0.2 104 units/mm3) and deoxygenated haemoglobin (deOXYHb : 7.6 ± 0.3 104 units/mm3) did not change significantly during the MVC task (13.9±0.2 and 7.8±0.3 104 units/mm3, respectively, P>0.065), however, the total haemoglobin (TOTALHb : 22.1±0.3 104 units/mm3) showed a significant increase (22.7±0.3 104 units/mm3, P=0.003) during the MVC. Tissue blood oxygen saturation was not changed during the MVC (P=0.164). During the tooth grinding task, OXYHb, deOXYHb, TOTALHb, and tissue blood oxygen saturation (StO2) remained constant (P>0.127). Finally, the chewing task was associated with significant decreases in StO2 (67.9±0.7%, P=0.006) related to a decrease in OXYHb (14.0±0.2 104 units/mm3, P=0.040) compared to baseline (68.8±0.7% and 14.2 ±0.3 104 units/mm3, respectively). Conclusion : These results showed that high-intensity experimental tooth clenching caused constriction-like reactions in the masseter muscle whereas tooth grinding did not cause detectable changes in haemodynamic characteristics of masseter muscle. Finally, the findings indicated that rhythmic dynamic contractions might lead to oxygen deficit in the masseter muscle. The present data may have implications for understanding the potential pathophysiological consequences of different types of oral-motor tasks, e.g., bruxism and prolonged mastication., 10526601

Road to master DC/TMD (Diagnostic Criteria for Temporomandibular Disorders)
ARIMA Taro
Gakukansetsu Kenkyukaishi, 27, 2, 87, 92, The Japanese Society for Temporomandibular Joint, 2015, [Invited], [Lead author, Last author, Corresponding author]
Japanese, In February 2014, DC/TMD (Diagnostic Criteria for Temporomandibular Disorders) was published as a clinical diagnostic tool as well as for research purposes. DC/TMD protocol underwent progressive improvement from RDC/TMD (1992) by a working group [consisting of members of the International RDC/TMD Consortium Network of the International Association for Dental Research (IADR), members of the Orofacial Pain Special Interest Group (SIG) of the International Association for the Study of Pain (IASP), and members from other professional societies] especially focusing on establishing its validity. The significant merit of DC/TMD was to obtain the sensitivity and specificity of each diagnosis of the most common TMDs (temporomandibular disorders). DC/TMD protocol contains both the proper clinical examination protocol and the diagnostic criteria of common pain-related TMD and joint problems. This classification system was based on the biopsychosocial model and the intent was to simultaneously provide a physical diagnosis and identify other relevant characteristics of the patient that could influence the expression and thus management of their TMD. The aim of this article is to introduce the steps of mastering DC/TMD. This article is based on my own experience studied through the subjects authorities (Professor Peter Svensson, Aarhus University, Denmark and Professor Thomas List, Malmo University, Sweden). Additionally, I would like to mention the future aspects of DC/TMD quoting the comments from the expert panels.

Journal of Dental Research, 91, 6, 562, 567, SAGE Publications, Jun. 2012, [Peer-reviewed], [Corresponding author]
English, Scientific journal, This study compared the jaw-muscle electromyographic (EMG) activity during sleep in patients with craniofacial pain (n = 63) or no painful conditions (n = 52) and between patients with tension-type headache (TTH: n = 30) and healthy control individuals (n = 30). All participants used a portable single-channel EMG device (Medotech A/S) for four nights. There was no significant difference in EMG activity between craniofacial pain (24.5 ± 17.9 events/hr) and no painful conditions (19.7 ± 14.5), or between TTH (20.8 ± 15.0) and healthy control individuals (15.2 ± 11.6, p >.050). There were positive correlations between EMG activity and number of painful muscles (r = 0.188; p = 0.044), characteristic pain intensity (r = 0.187; p = 0.046), McGill Pain Questionnaire (r = 0.251; p = 0.008), and depression scores (r = 0.291; p = 0.002). Patients with painful conditions had significantly higher night-to-night variability compared with pain-free individuals (p < 0.050). This short-term observational study suggests that there are no major differences between patients with different craniofacial pain conditions and pain-free individuals in terms of jaw-muscle EMG activity recorded with a single-channel EMG device during sleep. However, some associations may exist between the level of EMG activity and various parameters of craniofacial pain. Longitudinal studies are warranted to further explore the relationship between sleep bruxism and craniofacial pain., 10526604

Archives of Oral Biology, 54, 3, 241, 249, Elsevier BV, Mar. 2009, [Peer-reviewed], [Lead author], [International Magazine]
English, Scientific journal, AIM: To investigate effect of capsaicin-evoked masseter-muscle pain on intramuscular blood-flow (BF) at rest and during contractions. METHODS: Eight healthy men (22-31 years) participated. BF was measured with Laser Doppler (Moor Instruments, UK) using a single-fibre probe inserted into the right masseter. Three BF probes were attached to the skin above right and left masseter and the right-middle finger. Subjects performed 30 s isometric contractions at 5%, 15%, and 25% of maximal voluntary contraction. After the contractions, capsaicin (0.1 mL, 100 microg/mL) was injected into the right masseter close to the fibre probe. When the pain sensation had disappeared, the series of submaximal contractions were repeated. BF data were sampled continuously, processed in 10s bins, and analyzed with repeated-measures ANOVAs. RESULTS: Intramuscular BF significantly increased immediately after capsaicin injection (P < 0.050) and rapidly (30 s) decreased to pre-injection values. A significant increase in cutaneous BF above the right masseter was observed (P < 0.050) and lasted for 10 min, while a significant BF decrease in the finger (P < 0.050) was observed. The contractions were associated with increases in intramuscular BF before and after the injection (P < 0.022) and the contraction levels were also associated with increase in intramuscular BF before injection (P=0.008) but not after injection (P = 0.314). CONCLUSIONS: This study demonstrated BF increased by muscle contraction but failed to show effects of contraction levels on BF in a muscle exposed to nociceptive stimuli. Neurogenic inflammation in muscles could possibly be mediated via antidromical effects and local release of vasoactive substances. The decreased BF in the finger could be due to involvement of central regulatory mechanisms.

JOURNAL OF PERIODONTAL RESEARCH, 38, 5, 482, 487, Oct. 2003, [Peer-reviewed], [International Magazine]
English, Scientific journal, OBJECTIVES: This study aimed to establish a reliable method for detecting the threshold for perception of force applied to tooth and to report the basic properties of force threshold in the normal dentition subjects. BACKGROUND: The perception of mechanical stimulation exerted to tooth is formed by input from periodontal ligament mechanoreceptors and intradental mechanoreceptors. Periodontal ligament mechanoreceptors respond to a wide range speed of stimulus, whereas intradental mechanoreceptors are activated only by a rapid stimulation. Reliable properties of perception have not been reported because of the difficulties to regulate velocity and degree of the stimulus. METHODS: Eighteen healthy subjects were observed in this study (mean age: 27.2 +/- 5.7 years). A loading device to generate slow speed loading was fabricated and measured as follows: (i) the fluctuation of the force threshold within a day, (ii) day-to-day fluctuation, (iii) changes in the force threshold by a transient mechanical loading. RESULTS: In the normal dentition, it was observed that the fluctuation within a day and day to day of the pressure sense showed no significant differences; however, a transient mechanical loading caused the sensitivity of the periodontal ligament to decrease significantly. CONCLUSIONS: The device examining the force threshold resulted from periodontal ligament mechanoreceptors was useful in evaluating the sensitivity of the periodontal ligament.

症例は25歳女性で、5年前に他院で上顎左7と下顎左6-7の齲蝕歯を保存不可能といわれ抜歯、暫間的に下顎遊離端義歯を作製したが違和感が強く装着せず通院を中止し放置していたが、咀嚼障害を主訴に来院となった。本症例の33年間の経過観察により次のことが明らかとなった。下顎左7のインプラントは、周囲の骨吸収がシリンダー内外貫通孔に達した時点で急激に骨吸収が進んだが、早期のインプラント除去により吸収した骨の回復を認めた。下顎右5のヘミセクション根は遠心壁尖部が近心側に回転・挺出して水平状態となり、下顎右6のインプラント近心側歯槽骨が挙上、下顎右6のインプラント周囲骨の保護に役立った。上顎左6はペリオの問題があり連結固定を行ったが、固定除去が遅れ歯槽骨の吸収が進行、抜歯後も骨の回復は認めなかった。上顎右6のヘミセクション根は固定連結後に骨吸収が進行、早期に連結固定を外したため歯根が挺出し歯槽骨の回復を認めた。以上より、メタルフレーム内蔵のレジンジャケットブリッジはペリオに問題のある歯やデンタル・インプラントにも適用可能と考えられた。, (一社)北海道歯科医師会, Japanese

This project aimed that development of laser assisted etching with acid solution and of new adhesive procedure on ceramics would achieve. Treatment with acid solution created deep porous surface on ceramic, whereas air abrasion formed shallow micro retentive structure on it. Concerning the adhesive strength between ceramic and resin luting material hydrofluoric acid etching achieved the highest strength value compared to the other groups. Both phosphoric acid etching and adhesive primer treatment also brought the higher adhesiveness compared to air abrasion, but either phosphoric acid etching alone or silane coupling treatment alone did not have higher bond strength to resin cement brought. Treating with phosphoric acid etching alone on ceramic detected the lowest strength value among all the test groups.

Hyperactivity or abnormal contractions of craniofacial muscles, e.g. bruxism, are traditionally linked to pain and unpleasantness in the active muscles. The aim of this study was to investigate the effects of different standardized craniofacial muscle contractions on perceived muscle symptoms. All muscle contraction tasks evoked significant increases scores of pain, unpleasantness, fatigue, and mental stress. The results showed that submaximal static contractions of different craniofacial muscle groups could evoke mild to moderate levels of transient symptoms. The fatigue resistance may differ between different muscle groups. Further studies are warranted to better understand the contribution of specific craniofacial muscle groups for the characteristic presentation of musculoskeletal pain conditions in the head.

Apr. 2012 - Mar. 2015
OHATA Noboru; ARIMA Taro
The aim of this study was to investigate if a low-level but long-lasting tooth-clenching task initiates TMD symptoms. Eighteen healthy participants (24.0±4.3 years) performed and repeated an experimental 2-hour tooth-clenching task at 10% maximal voluntary occlusal bite force at incisors for three consecutive days (Days 1-3). The task evoked pain in the masseter/temporalis muscles and temporomandibular joint after 40.0±18.0 min with a peak intensity of 1.6±0.4 on 0-10 numerical rating scale after 105.0±5.0 minutes (Day 1). On Day 2 and Day 3, pain had disappeared but the tasks, again, evoked pain with similar intensities.The area under the curve of pain NRS in the masseter on Day 2 and Day 3 were smaller than that on Day 1 (P = .006). Prolonged, low-level tooth clenching evoked short-lived pain like TMD. This intervention study proposes that tooth clenching alone is insufficient to initiate longer lasting and self-perpetuating symptoms of TMD.

This project researched on the benefit of laser assist etching as a surface treatment of zirconia, alumina, or lithium disilicate used for all-ceramic restorations. The shear bond strength with the CO2 laser yielded the higher value compared the air abrasion of alumina with the power setting of the laser. And the hydrofluoric acid etching made the micro-grooved surface, while the air abrasion conventionally brought the micro retentive surface on the contrary. The hydrofluoric acid etching moreover led the effectiveness of the improvement for the bond strength to resin cements.

ARIMA Taro
The aim of this study was to characterise haemodynamic reactions in the human masseter muscle evoked by different types of experimental jaw-muscle contractions using non-invasive method. The generally healthy subjects performed the following four standardized oral-motor tasks: (1) maximal voluntary contractions, (2) tooth grinding, (3) gum chewing, and (4) very low level but for two hours of tooth clenching task repeated for three days. The results showed that high-intensity experimental tooth clenching caused constriction-like reactions in the masseter muscle whereas rhythmic tooth grinding did not cause detectable changes in haemodynamic characteristics of masseter muscle.

It was reported that EMD had promoted periodontal ligament cells to populate and make new cementum. This study suggested that application of enamel matrix derivative（EMD）had promoted the new connective tissue attachment in the periodontal cultured model. The periodontal regeneration was different from implantation methods of the combination of EMD and bone morphogenetic protein (BMP). This study suggested that implantation method of the separate EMD from BMP could enhance periodontal regeneration.

This study investigated the changes of kinematics of blood oxygenation in masseter muscle during sleep bruxism. The results showed that oxygenated hemoglobin and total hemoglobin decreased during mixture of phasic and tonic masseter muscle activity during sleep bruxism. Deoxygenated hemoglobin did not change during the mixed masseter muscle activity. The oxygenated situation was increased after the mixture of masseter muscle activity.

Normal subjects and patients with speech disorder with cerebrovascular accident participated in this study. The magnetic resonance(MR) imaging of the head of the subjects were taken during the subject kept the tongue position right before pronounce [ta],[na],[ka],[ra]. From these MR images, the distance between the tongue surface and the palate was measured at 140 points for each subject. The data base of average oral cavity volume for each pronounce ([ta],[na],[ka],[ra]) were made from the data of normal subjects. However, it was difficult to take fine MR Images of the patients with cerebrovascular accident. Because the time of taking MR images (3 minutes for one pronounce) seemed to be too long for the cerebrovascular accident patients to keep the tongue position right before pronounce.
The data base of oral cavity volume during pronounce in the normal subjects could be an important information for continuous studies about analysis of oral cavity volume during pronounce in the cerebrovascular accident or oral cancer patients. From the view point of, for instantly, designing the speech aid for those patients, it is predicted that the data base based from the oral cavity volume in speech could be highly needed.
