Biopsy specimens removed for examinations are immediately placed in
1) 10 % ethanol
2) 10 % formalin
3) Hydrogen peroxide
4) 1 % formalin
Oral Surgery
Answer: 2
Formalin, specifically 10% neutral buffered formalin, is the standard fixative used for preserving biopsy specimens. It helps to maintain the tissue architecture and cellular details, making it suitable for histopathological examination. Ethanol is not typically used for routine tissue fixation as it can cause tissue shrinkage and distortion. Hydrogen peroxide is not a fixative and is used for different purposes, such as disinfection. A 1% formalin solution is too dilute for effective fixation.

The treatment of choice for TMJ ankylosis is
1. exercise and warm packs
2. condylectomy
3. steroid therapyv
4. sclerosing solutions
Oral Surgery
Answer: 2
The treatment of choice for TMJ ankylosis is condylectomy. This is a surgical procedure where the ankylotic tissue is removed from the temporomandibular joint, allowing for the restoration of normal joint movement.
Exercise and warm packs may be used as adjunctive treatments to help manage the symptoms of TMJ ankylosis and maintain joint mobility, but they are not the primary treatment for the condition itself. Steroid therapy and sclerosing solutions might be used in some cases, but condylectomy is the definitive surgical procedure to address the ankylosis directly by removing the bony or fibrous tissue that is obstructing the joint..
