A large number of disorders affecting the masticatory system can cause restriction of mouth opening. The most common conditions related to this problem are those involving the temporomandibular joint (TMJ) and the masticatory muscles, when facial pain also is an usual finding. Congenital or developmental mandibular disorders are also possible causes for mouth opening limitation, although in a very small prevalence. Coronoid process hyperplasia (CPH) is an example of these cases, characterized by an excessive coronoid process growing, where mandibular movements become limited by the impaction of this structure on the posterior portion of the zygomatic bone. This condition is rare, painless, usually bilateral and progressive, affecting mainly men. Diagnosis of CPH is made based on clinical signs of mouth opening limitation together with imaging exams, especially panoramic radiography and computerized tomography (CT). Treatment is exclusively surgical. This paper presents a case of a male patient with bilateral coronoid process hyperplasia, initially diagnosed with bilateral disk displacement without reduction, and successfully treated with intraoral coronoidectomy. It is emphasized the importance of differential diagnosis for a correct diagnosis and, consequently, effective management strategy.

This research aimed to evaluate mandibular movements in children with and without signs and symptoms of temporomandibular dysfunction. The sample taken consisted of 99 children aged 3 to 5 years distributed in two groups: I - Absence of signs and/or symptoms of TMD (25 girls/40 boys); II - Presence of signs and symptoms of TMD (16 girls/18 boys). The symptoms were evaluated through an anamnesis questionnaire answered by the child's parents/caretakers. The clinical signs were evaluated through intra- and extraoral examination. Maximum mouth opening and left/right lateral movements were measured using a digital caliper. The maximum protrusive movement was measured using a millimeter ruler. The means and standard deviations for maximum mouth opening in Group I and Group II were 40.82mm±4.18 and 40.46mm±6.66, respectively. The values found for the left lateral movement were 6.96mm±1.66 for Group I and 6.74mm±1.55 for Group II, while for the right lateral movement they were 6.46mm±1.53 and 6.74mm±1.77. The maximum protrusion movements were 5.67mm±1.76 and 6.12mm±1.92, in Groups I and II, respectively. The mandibular movement ranges neither differed statistically between groups nor between genders. FAPESP Process 96/0714-6.

Coronoid process hypertrophy (CPH) consists of an abnormal volumetric increment of the mandibular coronoid process; as this process grows gradually, the infratemporal space needed for the rotation and translation of the mandible is reduced, which results in a reduction of the range of mouth opening and lateral excursion, limiting mouth opening. The purpose of this case report was to describe a rare case of hypertrophy of coronoid processes with associated temporomandibular ankylosis, monitored for over 20 years. The patient was first visited when he had a facial trauma at the age of 4. Then he was followed through clinical, functional, instrumental, bi-dimensional and three-dimensional radiological evaluations up to the age of 24. Physical therapy was initiated at the age of 10 to improve the condition of the masticatory muscles, while at the age of 14, Transcutaneous Electrical Nerve Stimulations were performed to reduce muscle tension and, a bite plane was delivered to control the parafunctional activity of the jaw in the night and self-control instruction was provided for daytime habits. The adult patient has not accepted surgical intervention; thus, the future objective is to continue monitoring over the years to avoid a detrimental progression of the medical condition through physical and functional therapies while waiting for patient consent to surgery if needed.

Bruxism is a parafunctional activity of the masticatory system, which is characterized by clenching or scraping of teeth. This condition is often accompanied by a change in the shape and size of the teeth, as well as the function of the stomatognathic system. Bruxism can occur during sleep and in the waking state. The etiology is multifactorial and all causes can be divided into peripheral and central. The clinical signs and symptoms of bruxism are primarily characterized by temporomandibular disorders, the appearance of bruxofacets and changes in the hard dental tissues, supporting apparatus of the teeth and masticatory muscles, as well as headaches. The diagnosis of bruxism is made on the basis of anamnesis and clinical signs and symptoms, while electromyography and polysomnographic analysis are used in scientific researches. Therapy is aimed at controlling etiological factors and reducing symptoms. Occlusal splints are the most commonly used in the treatment of bruxism. Medications are used in situations when other methods, including psychotherapy, do not give positive results. Given the multifactorial etiology, the therapeutic approach must be multidisciplinary. The approach to the patient must be individual in order to treat as effectively as possible.

BACKGROUND: Coronoid process hyperplasia is an uncommon finding, characterized by an enlargement of the coronoid process, causing a mechanical obstacle by its interposing in the posterior portion of the maxilla or zygomatic arch.CASE PRESENTATION: The article presents a case report of a bilateral coronoid process hyperplasia in a 3-year-old girl demonstrated with inability to open the mouth and restricted jaw movement. Panoramic x-ray and 3-dimensional computed tomographic reconstruction showed bilateral elongation of the coronoid processes associated with deformation of the mandibular condyle with no involvement of the articular space. A coronoid resection by intraoral approach was done, followed by an aggressive physiotherapy. A considerable improvement in mouth opening of 30 mm was achieved. We strongly suggest early surgical treatment of coronoid hyperplasia to recover morphology and function consequently to reduce skeletofacial deformities in young patients.CONCLUSIONS: The article presents a clinical and surgical case of bilateral coronoidectomy in a 3-year-old girl, with retrognathic mandible. The diagnosis of bilateral coronoid process hyperplasia was confirmed, and the surgical treatment was under general anesthesia, with nasotracheal intubation guided by a nasofiber endoscope, using an intraoral approach.

During the clinical examination, 620 military personnel (502 men and 118 women) aged 25 to 55 years serving in the land forces of the Armed Forces of the Russian Federation, determined the incidence and severity of the pathology of the temporomandibular joint and masticatory muscles. A clinical study was performed using a survey, clinical examination, auscultation of the temporomandibular joint, and the determination of the tone of the masticatory muscles. To identify the temporomandibular joint pathology, the degree of mouth opening, the presence of mandibular deviation during opening and closing of the mouth, the presence of sound phenomena in the temporomandibular joint during mandibular movements, as well as the presence of arthralgia in the state of physiological rest and during lower jaw movements were evaluated. Symptom analysis to assess the severity of the temporomandibular joint pathology was carried out in points. To identify and determine the severity of the clinical course of the pathology of the masticatory muscles, a technique was used in the work that allows such an assessment in points based on the severity of complaints of fatigue of the masticatory muscles, compression or gnashing of teeth, the presence of hypertrophy or hypertonus of the masticatory muscles, and the presence of generalized forms of periodontitis and or) increased tooth wear. It was found that diseases of the temporomandibular joint in male military personnel are less common (12,8%) than female military personnel (22,9%), while parafunctional masticatory muscles are more common in men (2,4 %) than women (1,7%). Pathology of the temporomandibular and masticatory muscles, regardless of gender and age, usually combines, aggravates each other, and in 25-66,7% of cases occur in moderate or severe. It has been shown that in the course of planned in-depth medical examinations of military personnel, it is necessary to identify persons with clinical signs of pathology of the temporomandibular joint and masticatory muscles, and send them to the military medical organizations to clarify the diagnosis and conduct specialized treatment. It is noted that it is advisable for dentists when conducting scheduled in-depth examinations or military-medical examination it is advisable to carry out auscultation of the temporomandibular joint with the use of an electronic stetofonendoskop and myotonometry of the chewing muscles proper. This, with minimal time, will significantly increase the efficiency of detecting temporomandibular joint and masticatory muscles in military personnel.

ABSTRACT The treatment of external root resorption and associated periodontal defect can be challenging to the most ingenious clinician. A correct diagnosis and an understanding of the etiology and dynamics of root resorption, which is the progressive loss of dentin and cementum through action of osteoclastic cells, are critical for effective management. The article describes the management of an external root resorption in maxillary central incisor where a combined endo-perio management strategy was implemented. Cone beam computed tomography was used as an adjunctive diagnostic aid. A combined approach using biodentine for root surface repair, bone graft, collagen membrane, and platelet-rich fibrin to address the associated osseous lesion appears to be viable modality in treatment of the same. After a follow-up period of 12 months, the patient was found to be asymptomatic. Postoperative radiographs also demonstrated satisfactory bone fill and arrest of the resorptive lesion.

BACKGROUND Masticatory system is a complex functional unit, primarily engaged in chewing, swallowing and breathing functions, and some parts are involved in taste recognition and determination of food consistency. Sophisticated functional performances of speech and emotional expressions are specifically human qualities. Irregularities in occlusion appears to be the precipitating factor in the pathogenesis of myofascial pain dysfunction syndrome. Tek- Scan III records the bite length, number, distribution, timing, duration and the relative force of each tooth contact. It also records the sequence of occlusal contacts in terms of time and the associated force with each occlusal contact. The aim of this study was to treat masticatory muscle disorders with occlusal equilibration, and compare the efficacy of treatment outcomes between selective grinding and stabilization splints using Tek-Scan III. OBJECTIVE Objective of this study was to compare the efficacy of occlusal equilibration achieved through selective griding and stabilization splints using Tek-Scan III. METHODS In this in vivo study, 40 patients with masticatory muscle disorders were selected based on the inclusion and exclusion criteria. The occlusal discrepancies were analyzed using Tek-Scan III. The selected 40 subjects were then randomly divided into 2 groups based on the treatment they recieved; Group I – Selective grinding group (20) and Group II – Stabilization splint group (20). Comparison of pre-treatment and post treatment results were evaluated in terms of pain, mouth opening, left and right side force percentage as recorded through Tek-Scan III and reduction of disclusion time. Statistical analysis was carried out with Kolmogorov Smirnov test, Wilcoxon matched pair test and Mann-Whitney U test. RESULTS Wilcoxon matched pairs test demonstrated that there was statistically significant results ( p = 0.0007) in both the groups for reduction of disclusion time, elimination of pain and improved mouth opening. Patients in Group I showed better results as compared to Group II in terms of disclusion time, pain and mouth opening. CONCLUSIONS Occlusal equilibration brought about by reducing the disclusion time using the Tek- Scan III reduced the symptoms of pain in masticatory muscles. Patients in group I (Selective grinding) however showed better results when compared to patients in group II (Stabilization splints).

41 women with osteoporosis were examined. The age of the examined people ranged from 50 to 60 years. All the women were postmenopausal. As a result of the study, it was found that the most effective management strategy for such patients is a combination of menopausal hormone therapy and non-hormonal drugs that affect calcium metabolism in bone tissue, improve its metabolism and reduce resorption. If there are contraindications to MGT, prevention and treatment of osteoporosis should also be carried out using the appointment of non-hormonal drugs. In this case, the use of ipriflavone is effective.
