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..

ProsthodonticsFor a complete ceramic crown, the Tinner's joint (butt joint) is placed lingually to hide the metal-ceramic junction from esthetic view. This placement ensures that any visible margin appears as ceramic rather than metal, maintaining optimal esthetics especially in the anterior region where the lingual placement keeps the joint hidden from normal viewing angles.

RadiologySubmentovertex view should be avoided in patients with cervical spondylitis because it requires extreme hyperextension of the neck. This positioning can cause severe pain, neurological complications, or injury to the cervical spine in patients with existing cervical pathology. Alternative views should be used.

Oral SurgeryIn children, the healing process for fractures is faster due to the high vascularity and rapid bone turnover in growing tissues. Mandibular fractures in children are typically immobilized for a shorter duration compared to adults, as prolonged immobilization can interfere with the growth of the jaw. Immobilization for 3-4 weeks is generally sufficient to allow proper healing without compromising growth.

ProsthodonticsNone of the listed conditions allow safe RPD construction without medical consultation. Diastolic pressure >130mmHg indicates severe hypertension, uncontrolled seizures pose safety risks, and uncontrolled arrhythmia requires cardiac evaluation. All these conditions require medical clearance and management before dental treatment can proceed safely.

General Medicine
In restrictive lung disease, the FEV1/FVC ratio and compliance of the lung are
decreasing.
Restrictive lung diseases, such as pulmonary fibrosis or severe asthma, are
characterized by a decrease in the lung's ability to expand due to factors like
stiffening of the lung tissue or a reduction in the volume of the thoracic
cavity. As a result, the forced expiratory volume in one second (FEV1) is
reduced in relation to the forced vital capacity (FVC), leading to a decreased
FEV1/FVC ratio. Additionally, the compliance of the lung, which is a measure of
the lung's ability to expand and contract, is also decreased in these conditions
because the lung tissue becomes less elastic.
