Extraction in irradiated bone carries a high risk of Osteoradionecrosis (ORN). RCT is preferred to manage the infection without surgical trauma to the bone.
Patient with recent tumoricidal radiotherapy needs treatment for a painful abscessed molar. Best approach?
1) ExtractionProliferative verrucous leukoplakia (PVL) is a high-risk form of leukoplakia with a very high rate of malignant transformation, often exceeding 70% in some studies. Speckled leukoplakia also has a significant malignant potential, higher than homogenous leukoplakia, but generally lower than PVL. Lichen planus has a much lower potential for malignancy.
Which has maximum malignant potential?
1) Speckled leukoplakia
2) Proliferative verrucous leukoplakia
3) Lichen planus
4) Leukoplakia
Garre's osteomyelitis predominantly affects young individuals (children and adolescents). Affecting primarily adults is the incorrect statement.
Which of the following is NOT a characteristic of chronic osteomyelitis with proliferative periostitis (Garre's osteomyelitis)?
1) Onion skin appearance on radiographs
2) Primarily affects adults
3) Inflammatory response leading to new bone deposition
4) Typically associated with low-grade infection
According to current AHA guidelines, antibiotic prophylaxis is recommended only for patients at the highest risk. Conditions that warrant prophylaxis include prosthetic valves, history of infective endocarditis, and certain cyanotic heart diseases. Mitral valve prolapse without regurgitation is no longer recommended for prophylaxis.
In which of the following conditions is antibiotic prophylaxis not recommended prior to invasive dental procedures, according to current AHA guidelines?
1. Presence of a prosthetic cardiac valve
2. Mitral valve prolapse without regurgitation
3. Unrepaired congenital cyanotic heart disease
4. History of infective endocarditis
Crepitus is the grating or popping sensation caused by friction between bone and cartilage, frequently seen in degenerative joint conditions like CBO.
During a clinical examination, a patient with Chronic Bone Overload (CBO) of the jaw exhibits audible cracking and popping sounds during mandibular movement. This clinical finding is documented as:
1) Crepitus
2) Trismus
3) Tinnitus
4) Luxation
Break point chlorination is the point where added chlorine satisfies the chlorine demand, after which free residual chlorine appears.
When chlorate in water starts to disappear and free chlorine starts to appear, it is called:
1) Break point
2) End point
3) Screen point
4) Flow point
The I-bar of the RPI system is an infrabulge clasp that provides push-type retention.
RPI clasp in a distal extension RPD:
1) For buccally tilted molarThe dense structure of the zygoma (cheekbone) and its zygomatic process often superimposes over the roots of the maxillary molars in standard dental radiographs (e.g., periapical views). This superimposition can obscure the view of the roots and surrounding bone.
Which of these structures hinders in imaging the roots of maxillary molars?
1) Zygoma and zygomatic process of maxilla
2) Orbital process of zygoma
3) Maxillary sinus
4) Palatine bone
The correct sequence for selective grinding of excursive movements in a denture during occlusion adjustment is typically: Balancing (medial or non-working) movements, Protrusive movements, and finally Working (buccal or lateral) movements. This sequence ensures stable and functional occlusion.
Which of the following is correct sequence for selective grinding of excursive movements in denture during occlusion?
1) Protrusive balancing working
2) Balancing protrusive working
3) Balancing working protrusive
4) Protrusive working balancing
