Oral PathologyMuscle cells are the most radioresistant cells.

Oral PathologySickle cell anemia has a strong racial predilection, being most prevalent in people of African descent (8-10% carry the sickle trait). This is due to evolutionary selection pressure in malaria-endemic regions where the sickle trait provides protection against malaria. The condition is also found in Mediterranean, Middle Eastern, and Indian populations. Other blood dyscrasias listed do not have such pronounced racial predilections.

Oral PathologyRadiation dose can be reduced by using speed films, filters, and increasing target-object distance.

Oral PathologyTarget cells (codocytes) are characteristic of thalassemia and appear as cells with a central dark area, clear ring, and outer dark rim resembling a target. Safety pin cells are also seen in thalassemia due to the abnormal hemoglobin distribution. Note that Cooleys anemia (option 4) is actually the same as thalassemia major, so both options 1 and 4 are technically correct, but thalassemia is the more general and preferred answer.

Oral PathologyThe function of the facial nerve is best tested by whistling.
44449
Oral PathologyIn thalassemia, there is actually a DECREASE (not increase) in globin chain production - either alpha or beta chains depending on the type. This imbalanced globin chain synthesis leads to unstable hemoglobin, increased erythrocyte fragility, hemolysis, and subsequent hypochromic microcytic anemia. Therefore, statement 1 is false, making it the correct answer to what is NOT true about thalassemia.

Oral PathologyElevated alkaline phosphatase levels are often used as a marker for increased bone turnover, which is prominent in both Paget's disease and fibrous dysplasia.

Oral PathologyIn Peutz-Jeghers syndrome, the oral lesions are characterized by silver pigmentation of the oral mucosa.

Oral PathologyThe speed at which electrons travel in a gas tube is primarily dependent on the potential difference between electrodes.

Oral PathologyThe unit of measurement to compare radiation damage is dose equivalent.
