Dra. Nívea Santos Miranda is a dental specialist in Palmas, Tocantins, Brazil, practising in the area of temporomandibular joint (TMJ) dysfunction and orofacial pain. Located at Quadra 108 Sul, Alameda 10, in the Plano Diretor Sul district of Palmas, the practice focuses exclusively on the diagnosis and treatment of conditions affecting the jaw joint, the masticatory muscles, and associated facial pain syndromes — a highly specialised field of dentistry that addresses problems frequently misdiagnosed or undertreated in general dental or medical settings.
Palmas is the capital of Tocantins, a state established in 1989 in the central-northern region of Brazil. The Plano Diretor Sul is the southern section of Palmas's planned urban centre, organised along a grid of numbered quadrants and lettered avenues. Specialist dental practices in this district serve patients from across the city and, given the scarcity of DTM specialists in the interior of Tocantins, often attract patients from neighbouring municipalities who require targeted care for chronic pain and jaw dysfunction.
The Specialist
Dra. Nívea Santos Miranda practises as a specialist in temporomandibular dysfunction (DTM, from the Portuguese Disfunção Têmporo-Mandibular) and orofacial pain. DTM specialists occupy a niche within dentistry that bridges dental treatment, neuromuscular physiology, and pain management. The temporomandibular joint — the joint connecting the lower jaw to the skull just in front of each ear — is one of the most frequently used joints in the body, involved in speaking, chewing, swallowing, and facial expression. When this joint or the muscles that control it are functioning abnormally, patients experience a range of symptoms including jaw pain, clicking or popping sounds, limited mouth opening, headaches, neck pain, earache, and facial pain that can significantly affect daily life.
Orofacial pain is a subspecialty that encompasses not only TMJ-related pain but also neuropathic facial pain, headaches related to dental structures, and conditions such as bruxism — the habitual clenching and grinding of teeth that generates abnormal forces on the jaw joint and muscles. Dra. Nívea Miranda's practice on the website dranivea.com.br emphasises bruxism as a core area of clinical focus, reflecting the high prevalence of bruxism-related complaints among patients with chronic jaw and facial pain.
Services
Dra. Nívea Santos Miranda provides specialist services in TMJ dysfunction and orofacial pain.
- TMJ dysfunction (DTM) assessment and diagnosis: clinical examination, jaw movement analysis, muscle palpation, and imaging review

- Bruxism treatment: management of tooth grinding and clenching and its consequences for the jaw joint and dentition
- Occlusal splint therapy: custom-fabricated intraoral appliances to reposition the jaw, protect the teeth, and reduce muscle overactivity
- Neuromuscular rehabilitation: exercises and therapies to restore normal jaw muscle function and range of motion
- Headache and myofascial pain management: treatment of pain originating in the masticatory muscles and associated structures
- Interdisciplinary referral: coordination with physiotherapy, neurology, and other specialties for complex pain cases
Occlusal splint therapy is one of the primary interventions in DTM and bruxism management. A splint — sometimes called a bite guard or nightguard — is a custom-fitted acrylic or thermoplastic appliance worn over the upper or lower teeth. It repositions the jaw into a more relaxed, therapeutically optimal position, prevents the teeth from grinding against each other, reduces the load transmitted to the temporomandibular joint, and allows the masticatory muscles to decompress. Splints are particularly effective for nocturnal bruxism and for patients with pain that worsens in the morning after clenching during sleep.
The diagnosis of orofacial pain conditions requires careful clinical assessment, as symptoms often overlap with those of other conditions — including inner ear disorders, cervical spine problems, and primary headache disorders. DTM specialists like Dra. Nívea Miranda are trained to distinguish between pain sources, to identify whether symptoms originate in the joint, the muscles, the dentition, or other structures, and to design treatment plans accordingly. For complex cases, collaboration with physiotherapists, neurologists, and otolaryngologists is often part of the treatment pathway.
