BACKGROUND bruxism is a rhythmic masticatory muscle activity that occurs involuntarily in a non-physiologically functional state.There is a lack of research classifying the functional status of masticatory muscles in patients with different mandibular movement types(centric clenching or eccentric grinding)of bruxism.AIM To assess the differences of the masticatory muscle activity in patients with different types of bruxism.METHODS A total of 21 subjects with centric bruxism(CB)and 21 subjects with eccentric bruxism(ECB)were screened from college students according to a questionnaire and their tooth wear features.Sixteen subjects with no bruxism were also recruited.The surface electromyography(EMG)signals of the temporalis anterior(TA)and superficial masseter muscle(MM)were measured in different mandibular positions and during the chewing task.The EMG amplitude and chewing cycle duration parameters were then analyzed.RESULTS The CB group showed fewer muscle maximal motor units,with the MM being more pronounced,a higher proportion of muscle contractions to be recruited for the same load of chewing activity,and a longer chewing cycle.The ECB group showed more TA maximal motor units and higher MM activity on the nonworking side in unilateral chewing.CONCLUSION CB mainly affects the MM,and patients with CB show reduced masticatory muscle contraction efficiency and chewing cycle efficiency.ECB mainly affects the TA,and patients with ECB show enhanced contraction of non-functional lateral muscle bundles.

A study of the temporomandibular joint during bruxism

引用

International Journal of Oral Science 2014年第2期6卷 116-123页

作者： María S Commisso Javier Martínez-Reina Juana Mayo Department of Mechanical Engineering University of Seville Seville Spain

A finite element model of the temporomandibular joint （TMJ） and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc. A quasilinear viscoelastic model was used to simulate the behaviour of the disc. The viscoelastic nature of this tissue is shown to be an important factor when sustained （awake bruxism） or cyclic loading （sleep bruxism） is simulated. From the comparison of the two types of bruxism, it was seen that sustained clenching is the most detrimental activity for the TMJ disc, producing an overload that could lead to severe damage of this tissue.

World Journal of Clinical Cases 2019年第4期7卷 516-524页

作者： Jia-Min Chen Ying Yan Department of Prosthodontics Guanghua School of StomatologyHospital of Stomatology Sun Yat-sen University Guangdong Provincial Key Laboratory of Stomatology

BACKGROUND bruxism is a jaw-muscle activity characterized by the clenching or grinding of teeth. It can be divided into nocturnal bruxism and diurnal bruxism(DB). DB secondary to antidepressants is rare and refractory. Reports associated with antidepressant-induced DB are mostly anecdotal without long-term follow-up.The effect of drug intervention on antidepressant-induced DB is still contested.We herein report the first case of successful treatment of venlafaxine-induced DB with an occlusal splint.CASE SUMMARY This case report describes detailed 7-year follow-up of a patient with venlafaxineinduced DB treated with an occlusal splint. The patient who complained about involuntary daytime tooth grinding after taking venlafaxine for a period of 4 mo and was diagnosed with venlafaxine-induced DB. Subsequently, an occlusal splint with modified bilateral buccal-pterygoid pads was used to treat his tooth grinding and to protect the dental structures from tooth wearing. The patient reported remission of symptoms after several months of treatment. His grinding activity was gradually and stably controlled after 2 years, with an almost complete recovery from DB after 6 years.CONCLUSION The maxillary buccal-pterygoid splint can be used as a noninvasive approach to treat venlafaxine-induced DB.

Open Journal of Stomatology 2023年第4期13卷 125-133页

作者： Audrey Morris Patricia Grabowski Tanya Al Talib Neamat Hassan Abubakr School of Dental Medicine University of Nevada Las Vegas Nevada USA

Aims: To evaluate the association between bruxism, headaches, and temporomandibular disorder (TMD). Methods: A keyword search of the clinical notes of patients’ charts in AxiUmTM was performed using the search terms “TMD”, “headache”, and “sleep bruxism” to identify these patients. The inclusion criteria were patients with partial of full dentition, aged 18 to 65 years old who attended the UNLV School of Dental Medicine clinics between January 2014 and September 2018. Patients with incomplete records and those who were completely edentulous formed the exclusion criteria. Data were analyzed using the Pearson Correlation Coefficient. Results: The final sample was made up of 529 patients. The highest percentage of study subjects were in the age range of 29 - 34 (17.9%), with a statistically significant correlation to pain on opening (P = 0.0403). Females showed a statistically significant correlation to TMJ clicking (P = 0.0033). Caucasians also had a statistically significant correlation to TMJ clicking (P = 0.0001). In addition, a statistically significant correlation between pain on opening or chewing and headaches was also observed (P = 0.0081). Conclusion: Within the limitations of the present study, Caucasians, and females presented with more TMJ clicking than the other study subjects. Young adults, in particular, experienced more pain on opening or chewing.

Recently, bruxism became the center of attention for the etiological research of non-carious cervical lesions (NCCLs). The present study aims to investigate the presence and types of NCCLs associated with bruxism. Retrospective keywords search of the clinical notes of all patient charts in axiUmTM was performed using the terms “bruxism”, “attrition”, “abrasion”, “erosion”, and “abfraction”. All bruxer patients 18 years and older who presented to the UNLV School of Dental Medicine (01/01/2014 to 09/30/2018) with the complete record were included. To determine the statistical analysis implications, the chi-square test was used. Commonest types of NCCL associated with bruxism were attrition and abfraction. Five hundred seventeen cases had multifactorial lesions. Anterior maxillary teeth followed by mandibular anterior were the most affected teeth. Abfraction lesions were mainly sighted in maxillary premolars, followed by maxillary canines. Within the limitation of the present investigation, it was concluded that attrition and abfraction were highly associated with bruxism.

Open Journal of Stomatology 2014年第1期4卷 1-4页

作者： Xuemeng Yin Xinmin Yin Department of Stomatolagy Benq Medical Center Nanjing Medical University Nanjing China

Objective: To evaluate the effect of wireless biofeedback therapy on bruxism. Methods: Fifteen bruxiers participated to be treated by this therapy. The abnormal movements of teeth during sleep were monitored by a maxillary splint with an electric resistance strain gauge. Meanwhile, the receiver device recorded these details and analyzed the data, including the value of the biting force, occurring time and duration. If the value of biting force or duration exceeds the threshold, a vibrating device like a watch style will alert the patient to relax the masticatory muscles and nervous system to stop the abnormal grinding or clenching. Data were recorded during 8 hours’ sleep and analyzed after the 12 weeks’ treatment and 24 weeks’ treatment. Results: The average episodes of bruxism have declined from (10.60 ± 1.23) to (6.60 ± 0.75) after 12 weeks’ treatment (p bruxism events was reduced from (13.2 ± 0.74) s to (6.50 ± 0.40) s (p bruxism have declined to (3.80 ± 0.64) after 24 weeks’ treatment, and the average duration of bruxism events was reduced to (3.37 ± 0.34) s (p bruxism treatment.

A Study of the electronic information monitoring of bruxism

引用

Journal of Nanjing Medical University 2008年第6期22卷 376-378页

作者： Jinglu Zhang Xinmin Yin Zongxin Yao Institute of Stomatology Nanjing Medical University Nanjing 210029 Jiangsu Province China

Objective：bruxism is the term used for teeth grinding or jaw clenching. An electronic monitor of bruxism was developed to evaluate bruxism duration and frequency. Methods： Ten cases were selected in the Department of Prosthodontics of Jiangsu Stomatological Hospital to evaluate the monitor. A stabilization occlusal splint was fabricated for each of the 10 cases. The vertical dimension for each splint was 0.5 nun lower than mandibular postural position. Some sensors had been prearranged at each splint which could transfer the variation of the biting force into electronic signals. The data of sleeping duration, grinding duration and grinding frequency were recorded with this new type of bruxism monitor, which had been specifically invented to study bruxism. Results：The data from 10 bruxism cases were collected and the results were considered reliable. Subjects nocturnal duration parameters did not change significantly from night-to-night. Conclusion：The bmxism monitor can automatically measure and record bruxism data using an occlusal splint. This device is valuable for diagnosis and evaluation of bruxism.

Noncarious Cervical Lesions: Correlation between Abfraction and Wear Facets in Permanent Dentition

引用

Open Journal of Stomatology 2015年第6期5卷 152-157页

作者： Felice Femiano Rossella Femiano Luigi Femiano Vincenzo Maria Festa Rosario Rullo Letizia Perillo Multidisciplinary Department of Medical-Surgical and Dental Specialties Second University of Naples Naples Italy

Non-carious cervical lesions (NCCLs) are defined as the loss of dental hard tissue at the cement-enamel junction. Erosion, abrasion, and attrition have been associated with this disorder. Objective: Recently, occlusal stress causing of cervical enamel cracks (abfraction) has been considered as an additional etiology for NCCLs to facilitate the erosion and abrasion mechanisms in tooth wear. Study Design: The prevalence of NNCLs and wear facets in a population with permanent dentition in absence of any clear etiological factors related to erosion and abrasion causes is evaluated. A total 295 subjects are enrolled for this study and divided into four age groups (subjects aged 15 - 27 years, 28 - 42 years, 43 - 57 years and 58 - 75 years respectively). An overall of 6629 teeth are investigated to find NCCLs and wear facets. The occlusion is analyzed in each patient. Results: An overall of 801 teeth (12%) show NCCLs and 623 of them (78%) highlight also wear facets. The higher number of teeth with NCCLs and of these with simultaneous presence also of wear facets are found on teeth of patients of group-3 (11% of all teeth examined for group and 81% respectively) and to group-4 (24.4% of all teeth examined for group and 86.5% respectively) of remaining teeth without NCCLs (5828) only 138 (2.4%) shown wear facets. Conclusion: The results of this study held the occlusal forces as the main cause of NCCLs on teeth in presence of wear facets.

Effect of Different Splint Thicknesses on Occlusal Function and Temporomandibular Joint Sounds:A Clinical Report

引用

Open Journal of Stomatology 2018年第12期8卷 326-337页

作者： Yuyao Tang Hefei Li Yuming Chen Lisha Zhu Hong Kang Department of Prosthodontics Lanzhou University School of StomatologyLanzhouChina

Background: Occlusal splint therapy, which is a conservative approach to treat temporomandibular disorders (TMDs) and bruxism, can change the occlusal contact of dentition. However, little is known about the variation in bite force and temporomandibular joint (TMJ) sounds. The objective of this case report is to compare the effects of different splint thicknesses constructed by vacuum lamination technology on occlusal function and TMJ sounds. Clinical Presentation: This study presents a 24-year-old male with bruxism. Four splints of different thicknesses (0.6 mm, 1 mm, 2.5 mm and 3 mm) were fabricated and tested. Then, an array of occlusal data were recorded and analyzed by the T-Scan?III system and joint vibration analysis (JVA). Conclusion: The results reveal that splints of different thicknesses manufactured by the vacuum hot-lamination apparatus may cause a change in occlusal force.
