Oral and Maxillofacial SurgeryA bull's eye appearance on an IOPA film suggests that the tooth is
lingually placed with its occlusal surface facing the tongue, which is
characteristic of a lingual impaction of a mandibular third molar.

Oral and Maxillofacial SurgeryDentists determine the position of an impacted tooth using an x-ray by evaluating its relationship with the nerve, the adjacent teeth, and other anatomical structures such as the maxillary sinus or the mandibular canal. This helps in planning the surgical approach for extraction and predicting potential complications.

Oral and Maxillofacial SurgeryPlain catgut is contraindicated in oral surgery due to its tendency to cause a pronounced tissue reaction. This reaction can lead to increased inflammation and a delay in the healing process, making it less suitable for procedures in the oral cavity where optimal healing is crucial.

Oral and Maxillofacial SurgeryNon-absorbable sutures are ideal for situations where sustained support is required beyond the typical healing period, ensuring that the tissue remains stable during the recovery process.

Oral and Maxillofacial Surgery
The primary function of sutures in oral surgery is to control bleeding and
stabilize the tissues involved. By holding the tissue flaps in place, sutures
protect the underlying structures and promote proper healing.
166048
Oral and Maxillofacial SurgeryThe lingual split technique minimizes bone loss and tissue trauma by dividing the tooth along its longitudinal axis and removing it in two halves, reducing the need for extensive buccal bone removal.

Oral and Maxillofacial SurgeryPolyglactin (Vicryl) is an absorbable, braided suture commonly used for tension-free wound closure.

Oral and Maxillofacial SurgerySilk sutures are known to provoke a moderate to
high tissue reaction, which is not ideal in oral surgery where minimal tissue
response is preferred for optimal healing.
