- C.
Prevent the damage to the socket of donor teeth
- D.
Bleeding control at the recipient side
Correct Answer
A. Because, Preventing from donor tooth expose to environment, that cause damage to periodontium cellExplanation
Before extracting a donor tooth, it is important to prepare the recipient side first. This is because exposing the donor tooth to the environment can cause damage to the periodontium cells. By preparing the recipient side beforehand, the donor tooth can be immediately placed into the socket, minimizing the time it is exposed to the environment and reducing the risk of damage to the periodontium cells.Rate this question:

What happen to the tissue pH at the infection side?
- A.
Low pH
- B.
High pH
- C.
Neutral pH
- D.
All are correct
Correct Answer
A. Low pHExplanation
During an infection, the body's immune response triggers the release of various chemicals, including hydrogen ions. These hydrogen ions contribute to the acidity of the area, resulting in a decrease in pH. This low pH environment is unfavorable for many pathogens, as it can inhibit their growth and survival. Therefore, the tissue pH at the infection site becomes low.Rate this question:

Clindamycin is in the group of:
- A.
Macrolid
- B.
Penicillin
- C.
Fluroquinolone
- D.
Septicemia
Correct Answer
A. MacrolidExplanation
Clindamycin belongs to the group of macrolide antibiotics. Macrolides are a class of antibiotics that inhibit bacterial protein synthesis by binding to the 50S ribosomal subunit. They are effective against a wide range of gram-positive bacteria, some gram-negative bacteria, and atypical pathogens. Clindamycin specifically is commonly used to treat infections caused by anaerobic bacteria and certain types of gram-positive bacteria. It is not a penicillin or a fluoroquinolone, and septicemia is a condition characterized by the presence of bacteria in the bloodstream, not a group of antibiotics.Rate this question:

What is the mycotic aneurysm?
- A.
Complication of arterial wall from hematogenous spread of bacterial infection
- B.
Complication by antibiotic prophylaxis
- C.
Infection to the mediastinum and spread the infection to the brain.
Correct Answer
A. Complication of arterial wall from hematogenous spread of bacterial infectionExplanation
A mycotic aneurysm is a complication that occurs when a bacterial infection spreads through the bloodstream and affects the arterial wall. This can weaken the wall and cause it to bulge, forming an aneurysm. It is called "mycotic" because it is often caused by a fungal infection, although bacterial infections can also be responsible. This condition is a serious medical concern as it can lead to rupture of the aneurysm and potentially life-threatening complications.Rate this question:

What is the Bactericidal antibiotic?
- A.
Antibiotics kill bacteria
- B.
Antibiotic limit growth of bacteria
- C.
Antibiotic resistant
- D.
Antibiotic sensitivity
Correct Answer
A. Antibiotics kill bacteriaExplanation
Bactericidal antibiotics are a type of antibiotic that directly kill bacteria. Unlike bacteriostatic antibiotics, which only inhibit the growth and reproduction of bacteria, bactericidal antibiotics actively destroy the bacteria, leading to their death. This is achieved by targeting specific components or processes within the bacterial cells, such as cell wall synthesis or protein synthesis, causing irreparable damage and ultimately killing the bacteria. Bactericidal antibiotics are often preferred in severe or life-threatening infections, where rapid elimination of the bacteria is crucial for the patient's recovery.Rate this question:

The correct answer is (1), (2), and (3) because a mesiodens is a supernumerary tooth that can cause crowding and displacement of other teeth. In this case, the child has a mesiodens, which is a small, extra tooth that has erupted in the midline of the maxilla. This can lead to crowding and displacement of the other teeth, causing the overbite. Braces (1) and extraction (2) are common treatments for correcting crowding and misalignment of teeth, while removing the mesiodens (3) can also help alleviate the overbite.Rate this question:

A. ααΆααααααααααα αα 3,5mm αα α’αααα mandibleExplanation
The mandible has a greater length of 3.5mm compared to the maxillary. This allows for more space and accommodation for the premolar teeth, which are larger than the incisors. The larger size of the premolars requires more room for eruption and growth, and the mandible provides this space. Additionally, the mandible undergoes more remodeling due to the forces exerted during chewing and biting, which may also contribute to its larger size compared to the maxillary.Rate this question:

The correct answer is the outer surface of enamel and dentin. This means that caries can start on the outer surface of both enamel and dentin. Caries, also known as tooth decay, is caused by the breakdown of the tooth structure due to acid produced by bacteria in the mouth. It typically starts on the outer layer of the tooth, which is the enamel, and can progress to the underlying layer called dentin. Therefore, both enamel and dentin surfaces are susceptible to caries.Rate this question:

The age-related decrease in salivary flow can contribute to the development of carious lesions on the surface of the teeth. Saliva plays an important role in maintaining oral health by neutralizing acids, remineralizing enamel, and washing away food particles and bacteria. When salivary flow decreases, the protective effects of saliva are reduced, making the teeth more susceptible to tooth decay. Therefore, the age-related decrease in salivary flow is likely to be a contributing factor to the development of carious lesions in this individual.Rate this question:

The correct answer is (1) Macrophages, (2) Plasma cells, and (3) Lymphocytes. These immune cells are all involved in the immune response to plaque in the periodontal pocket. Macrophages are responsible for phagocytosing and removing bacteria and debris in the pocket. Plasma cells produce antibodies to target and neutralize pathogens. Lymphocytes, including B cells and T cells, play a role in the adaptive immune response by recognizing and eliminating specific pathogens. Neutrophils, on the other hand, are not mentioned in relation to the immune response to plaque in the given information.Rate this question:

Correct Answer
A. αααααΆααα»ααα·ααα½αααΌαExplanation
The given answer states that the formation of plaque and calculus leads to bad breath. Plaque is a sticky film of bacteria that forms on the teeth and gums, and if not removed, it can harden into calculus (tartar). Both plaque and calculus can contribute to gum disease and tooth decay, which can cause bad breath. Therefore, the answer suggests that the accumulation of plaque and calculus is responsible for the bad breath.Rate this question:

Correct Answer
A. Epithelium αα oral mucosaExplanation
The correct answer for this question is the epithelium of the oral mucosa. This is because chronic hyperplastic pulpitis is a condition that affects the pulp of the tooth, and the epithelium of the oral mucosa is the tissue that lines the inside of the mouth and covers the gum tissue. Therefore, it is likely that the chronic hyperplastic pulpitis originates from the oral mucosa epithelium.Rate this question:

The correct answer is (4) ααααΉαααααΌα. This is because necrotizing ulcerative gingivitis is an infection of the gums that is often caused by bacteria. Antibiotics are commonly prescribed to treat this condition and help eliminate the infection. Therefore, it is appropriate to include antibiotic treatment as part of the management plan for a patient with lymphadenopathy and necrotizing ulcerative gingivitis.Rate this question:
