Dental trismus is defined by difficulty in opening the jaw. It is a temporary condition that usually lasts no more than two weeks. Dental trismus is caused by an injury to the masticatory muscles, such as opening the jaw for an extended period of time or having a needle pass through a muscle.
Scientists have proven that intralesional injection of autologous bone marrow stem cells is a safe and effective treatment modality in oral submucosal fibrosis. It has been shown autologous bone marrow stem cell injections induces angiogenesis in the lesion area, which in turn decreases the extent of fibrosis, thereby leading to significant ...
Intraosseous anaesthetic injection involves the deposition of anaesthetic solution directly into the cancellous alveolar bone adjacent to the apex of the root of the tooth to be anaesthetised through a small hole. Additionally, more complex dental procedures like surgery or endodontic therapy (like root canals) might make use of it.
Also if the needle is placed too medially the medial pterygoid muscle can be injected, resulting in trismus. The sphenomandibular ligament may act as a barrier to the agent if the injection is given too shallow and the lingual nerve is only anesthetized. [3] This injection can rarely cause needle tract infections of the pterygomandibular space.
Treatment may focus on poor posture, cervical muscle spasms and treatment for referred cervical origin (pain referred from upper levels of the cervical spine) or orofacial pain. MT has been used to restore normal range of motion, promoting circulation, stimulate proprioception , break fibrous adhesions, stimulate synovial fluid production and ...
‘The risk of MRONJ after dental extraction was significantly higher in patients treated with ARD (antiresorptive drugs) for oncological reasons (3.2%) than in those treated with ARD for OP (osteoporosis) (0.15%) (p < 0.0001). Dental extraction performed with adjusted extraction protocols decreased MRONJ development significantly.
Rarely, tetanus can be contracted through surgical procedures, intramuscular injections, compound fractures, and dental infections. [1] Animal bites can transmit tetanus. [1] Tetanus is often associated with rust, especially rusty nails. Although rust itself does not cause tetanus, objects that accumulate rust are often found outdoors or in ...
Due to its high vascularity, injections into the pterygomandibular space carry a high risk of intravascular injection (injecting into a blood vessel). [4] Another possible complication of an inferior alveolar nerve block occurs when the needle is placed too deep, passing through the pterygomandibular space and into the parotid gland behind.
