For a patient on warfarin therapy, the target INR (International Normalized Ratio) for undergoing minor oral surgery is typically 2-3. This range provides adequate thromboprophylaxis while minimizing the risk of excessive bleeding. However, the decision to proceed with surgery should be made on a case-by-case basis, considering the patient's overall health and surgical risks.

1. Infectious hepatitis (Hepatitis A virus): While HAV is resistant to some environmental conditions, it is generally less resistant than HBV.

2. Mumps virus: This is an enveloped virus and is not particularly resistant to environmental factors.

3. Influenza virus: This is also an enveloped virus and is susceptible to heat and many disinfectants.

4. Serum hepatitis (Hepatitis B virus): HBV is known for its resilience. It can survive outside the body for long periods and is resistant to many disinfectants and physical agents, making it one of the more resistant viruses.

Stereophotogrammetry is a highly accurate, non-invasive 3D imaging technique. The question suggests identifying which is NOT promising; however, in clinical context, Stereophotogrammetry is actually highly promising for soft tissue.

One advantage of digital radiography is that the radiographic images are obtained immediately.

The possibility that a distal step would become class II is very real, and this not self correcting problem. When the central incisors erupt, these teeth use up essentially all of the excess space in the normal primary dentition. With the eruption of the lateral incisors, space becomes tight in both arches.

Normal child will go through a transitory stage of mandibular incisor crowding at age 8 to 9 even if there will eventually be enough room to accommodate all the permanent teeth in good alignment. In other words, a period when the mandibular incisors are slightly crowded is a normal developmental stage.

Cleidocranial dysostosis is characterized by absent or hypoplastic clavicles, which is the pathognomonic feature of this condition. This allows patients to bring their shoulders together. Osteogenesis imperfecta affects bone fragility, fibrous dysplasia causes fibrous tissue replacement of bone, and osteopetrosis causes marble bone disease, but none of these affect the clavicles specifically.
