RESUMEN
Objectives: To access the knowledge of undergraduate and postgraduate students of the dental college on basic anatomy, physiology, clinical examination, and pathology of the temporomandibular joint (TMJ). Materials and Methods: A total of 610 undergraduate and postgraduate students of dental college, were included in this study. The questionnaire was pretested for validation and distributed online through Google forms. Results: A pairwise comparison showed that the percentage of correct answers for interns significantly differed from that of IV Bachelor of Dental Surgery (P=0.050) and postgraduate students (P=0.048) (below average: up to 6 correct answers, good: 7-11 correct answers, excellent: 12 or more correct answers). Conclusion: TMJ diseases are common in daily life but frequently go undiagnosed and untreated due to a lack of clinical expertise. This demonstrates the necessity of providing instructions that give students in-depth knowledge and abilities for TMJ issues in clinical practice.
RESUMEN
Background: Internal derangement (ID) of temporomandibular joint (TMJ) is a common temporomandibular disorder (TMD) which causes hypomobility of the joint. Minimally invasive treatment modality like arthrocentesis is used as first-line of management having low morbidity and high efficacy. This prospective randomized comparative study was carried to compare the efficacy of intra-articular injection with sodium hyaluronate (SH) and triamcinolone acetonide (TA) after arthrocentesis in ID of TMJ. Materials and Methods: A total 40 patients diagnosed with ID (stage 1-4) were included in the study and randomly divided in two groups. Twenty patients (group A) received intra-articular injection of SH while 20 patients (group B) received intra-articular injection of TA, after arthrocentesis. The clinical parameters of pain (VAS), Maximum mouth opening (MMO) (mm) and clicking sound (present/absent) were evaluated pre-operatively and at seventh day, 1 month and 3 months post-operatively. Results: There was statistically significant improvement in pain scores in both the groups at all time intervals with SH being superior (p value 0.0086). All the patients showed improved mouth opening at all time intervals, TA being superior but statistically insignificant (p value 0.59). There was reduction in the clicking sound in both the groups which was statistically insignificant at all time intervals. Conclusions: Arthrocentesis followed by intra-articular injection with SH is superior to TA in terms of pain reduction, while TA showed superiority in terms of improved mouth opening.
RESUMEN
Osteomyelitis is an inflammatory condition of the bones that often starts with an infection of the medullary cavity and swiftly extends to the haversian system and periosteum. If drainage and antimicrobials are ineffective, acute osteomyelitis may progress to chronic osteomyelitis. Here, we offer a unique case that analyzes the radiographic and clinical characteristics of osteomyelitis with underlying disease. Cysts and cyst-like lesions of the jaws must be diagnosed and evaluated using radiographic findings in conjunction with clinical complaints. This case study examines the circumstances that led to the diagnosis of osteomyelitis and demonstrates several noteworthy lessons. As decortication is less invasive and more effective at treating primary chronic osteomyelitis than peripheral or segmental excision of the jaw, and the use of vancomycin as local hard and soft tissue dressing over the surgical site, we emphasize its significance.
RESUMEN
Masseter hypertrophy (MH) is an uncommon disorder which can cause both aesthetic and functional problems. The most common aetiological factors associated with MH are habit of chewing gum, clenching and/or bruxism. The treatment of MH includes conservative management as well as surgical resection of the enlarged muscle and/or bone. Injection of botulinum toxin type A is a relatively new and minimally invasive method for management of masseter muscle hypertrophy, which offers many advantages over conventional surgical management. This paper reports a case of unilateral MH of unknown origin which was treated with injection of botulinum toxin type A, resulting in satisfactory reduction in the volume of muscle and improvement of facial aesthetics.
