4-Questions about Systematic desensitization
Systematic desensitization: exposing a patient to items from a collaboratively constructed hierarchy of slowly increasing anxiety-provoking stimuli (related to the target fear) while using relaxation skills.

In layman terms; Systematic desensitization is a behavioral technique whereby a person is gradually exposed to an anxietyproducing object, event, or place while being engaged in some type of relaxation at the same time in order to reduce the symptoms of anxiety. For example, a very common phobia is the fear of flying.

5- Probing depth is 2 mm on the facial surface of tooth 30 and the distance from free gingival to mucogingival junction is 3mm, what is the width of attached gingiva?


3mm (MJ)- 2mm(PD) = 1mm(remaining width) which is attached gingiv

6- What is best and most accurate diagnostic to check extent of periapical lesion with deep Cavity ?
A- cbct

CBCT is more accurate in determination of periapical lesions than other Parallax and occlusal radiographs which are recommended for the diagnosis of dental diseases

7- Too opaque porcelain?
-Inadequate reduction preparation

8- Cyclic neutropenia :
-periodic CBC

Cyclic neutropenia is a rare blood disorder characterized by recurrent episodes of abnormally low levels of neutrophil

9- Probing depth= 6mm, recession on facial surface 6mm, free gingiva is 2mm beyond the CEJ , what is the Clinical attachment loss?


10- Loss of fungiform papillae and macrocytic anemia, which vitamin deficiency ?


Atrophic glossitis (AG) is characterized by the partial or complete absence of filiform papillae on the dorsal surface of the tongue. AG may reflect the significant deficiencies of some major nutrients including riboflavin, niacin, pyridoxine, vitamin B12, folic acid, iron, zinc, and vitamin E.

11- During preparation Class 2 when do the pulpal floor perpendicular with the axial wall , which tooth has the most pulpal
exposure possibility?
-Max premolar

12- How does wheezing happen ?
Airflow through a narrowed or compressed segment of a small airway becomes turbulent, causing vibration of airway walls;
this vibration produces the sound of wheezing. Wheezing is more common during expiration because increased intrathoracic pressure during this phase narrows the airways and airways narrow as lung volume decreases. Wheezing during expiration alone indicates milder obstruction than
wheezing during both inspiration and expiration, which suggests more severe airway narrowing. By contrast, turbulent flow of air through a narrowed segment of the large, extrathoracic airways produces a whistling inspiratory noise
So difficult options , know it well


13- Gingival hypertrophy: Amyldipine(ask 2 times)
B/C Amlodipine, calcium channel blockers, lead to gingival enlargement
