What is the symptom of reversible pulpitis?
- A.
Sharp pain for short duration cause by stimulus
- B.
Sharp pain for an hour cause by stimulus
- C.
Sharp pain for 2 hours cause by stimulus
- D.
Sharp pain for 3 hours cause by stimulus
Correct Answer
A. Sharp pain for short duration cause by stimulusExplanation
The symptom of reversible pulpitis is sharp pain for a short duration caused by a stimulus. This means that when the tooth is exposed to a trigger such as hot or cold temperature, sweet or sour foods, or biting pressure, the individual experiences a brief but intense pain. The pain subsides quickly once the stimulus is removed. This symptom is characteristic of reversible pulpitis, which is an inflammation of the dental pulp that can be reversed with appropriate treatment.Rate this question:

The patient 5 years old come to the dental clinic with the complain of pain on tooth 75 and the pain is more severe and continue for a few minutes check the tooth have big hole. What treatment of choice would you choose?
- A.
Pulpectomy
- B.
Pulp capping
- C.
Pulpotomy
- D.
Extraction
Correct Answer
A. PulpectomyExplanation
Based on the given information, the patient is experiencing severe pain and has a big hole in tooth 75. A pulpectomy is the most appropriate treatment choice in this case. A pulpectomy involves the complete removal of the infected pulp tissue from the tooth's root canal and filling it with a suitable material. This treatment is usually performed when the tooth is severely decayed or infected, as in this case. Pulp capping and pulpotomy are not suitable because they involve preserving the pulp tissue, which is not possible in this situation. Extraction may be considered if the tooth cannot be saved through other means, but it is not the first choice in this case.Rate this question:

- D.
Warfarin
Correct Answer
A. CyclosporinExplanation
Cyclosporin is a drug that can cause gingival enlargement. This side effect is known as drug-induced gingival overgrowth, and it occurs due to an abnormal response of the gum tissues to the drug. Cyclosporin is an immunosuppressant medication commonly used in organ transplant recipients to prevent rejection. It is believed to cause gingival enlargement by stimulating the growth of fibroblasts and collagen in the gums. This can lead to an overgrowth of gum tissue, causing the gums to become swollen, red, and prone to bleeding. Regular dental care and good oral hygiene are important for individuals taking cyclosporin to minimize the risk of gingival enlargement.Rate this question:

Taurodontism is a dental condition characterized by an elongated pulp chamber and short roots. It can be caused by various factors, including oral-facial-digital syndrome, which is a genetic disorder affecting the development of the oral cavity, face, and digits. Amelogenesis Imperfecta-type IV, a hereditary enamel defect, can also lead to taurodontism. Additionally, individuals with Down syndrome, a chromosomal disorder, may exhibit taurodontism as part of their dental abnormalities. Therefore, all of the mentioned conditions can contribute to the development of taurodontism.Rate this question:

The patient 13 years old come to the dental clinic and complain of his teeth has bad color ( yellow, brown, grey) the enamel is soft. What is your diagnosis?
- A.
Amelogenesis Imperfecta
- B.
Enamel hypoplasia
- C.
Fluorosis
- D.
Dentinogenesis Imperfecta
Correct Answer
A. Amelogenesis ImperfectaExplanation
Based on the description provided, the patient's complaint of bad color and soft enamel suggests a condition that affects the development of tooth enamel. Amelogenesis Imperfecta is a genetic disorder that causes abnormal enamel formation, resulting in discolored and weak teeth. Enamel hypoplasia refers to underdevelopment of enamel, but it does not explain the color changes mentioned. Fluorosis is caused by excessive fluoride intake and leads to enamel discoloration, but it does not mention soft enamel. Dentinogenesis Imperfecta affects the dentin layer, not the enamel. Therefore, Amelogenesis Imperfecta is the most likely diagnosis.Rate this question:

Dentinogenesis Imperfecta can cause teeth:?
- A.
All of above
- B.
Discolor ( Blue, grey, brown, yellow)
- C.
Translucent
- D.
Making teeth prone to rapid wear
Correct Answer
A. All of aboveExplanation
Dentinogenesis Imperfecta is a genetic disorder that affects the development of tooth dentin, leading to various dental problems. It can cause teeth to have a discolored appearance, with shades of blue, grey, brown, or yellow. Additionally, the condition can make teeth translucent, giving them a glass-like appearance. Due to the abnormal development of dentin, the teeth become weak and prone to rapid wear, making them more susceptible to damage and decay. Therefore, all of the mentioned options are correct outcomes of Dentinogenesis Imperfecta.Rate this question:

Teeth that early obliteration of root canal and pulp chamber is seen in?
- A.
Dentinogenesis Imperfecta
- B.
Amelogenesis Imperfecta
- C.
Dentin dysplasia
- D.
Dentin hypocalcification
Correct Answer
A. Dentinogenesis ImperfectaExplanation
Dentinogenesis Imperfecta is a hereditary disorder that affects the development of dentin, the hard tissue that makes up the majority of a tooth. In this condition, the root canal and pulp chamber of the tooth are prematurely obliterated, meaning they are filled or closed off before they should be. This can lead to weakened teeth that are more prone to fractures and dental problems. Dentinogenesis Imperfecta is often characterized by discolored, translucent teeth that are prone to wear and tear.Rate this question:

Dentin dysplasia is cause from?
- A.
Genetic disorder
- B.
Traumatic
- C.
Overdose of fluoride
- D.
Dental caries
Correct Answer
A. Genetic disorderExplanation
Dentin dysplasia is caused by a genetic disorder. This means that it is a condition that is inherited from one or both parents. It is not caused by trauma, an overdose of fluoride, or dental caries. Genetic disorders are caused by changes or mutations in genes, which can affect the development and function of various body systems. In the case of dentin dysplasia, there is a defect in the development of dentin, which is the hard tissue that makes up the majority of a tooth.Rate this question:

In the dentin dysplasia premature tooth loss may occur because of?
- A.
Short root
- B.
Gingivitis
- C.
Periodontitis
- D.
Chronic pulpitis
Correct Answer
A. Short rootExplanation
In dentin dysplasia, premature tooth loss may occur due to short root. Dentin dysplasia is a genetic disorder that affects the development of dentin, the hard tissue that forms the majority of the tooth structure. Short root is a common characteristic of dentin dysplasia, where the roots of the teeth are underdeveloped and shorter than normal. This can lead to instability and weakness in the teeth, making them more prone to premature loss.Rate this question:

Dentin dysplasia type II (coronal type) show?
- A.
All of above
- B.
Color of primary dentition is opalescent
- C.
Coronal pulp are usually large
- D.
Root of primary teeth are very short
Correct Answer
A. All of aboveExplanation
The correct answer is all of the above. Dentin dysplasia type II (coronal type) is a rare genetic disorder that affects the development of dentin, the hard tissue that makes up the majority of a tooth. This condition can cause various dental abnormalities, including opalescent color of primary dentition, large coronal pulp, and short roots of primary teeth. Therefore, all of the given options are characteristic features of dentin dysplasia type II.Rate this question:

The cause of Dentin dysplasia type II is?
- A.
Inherited disorder
- B.
Genetic disorder
- C.
Traumatic factors
- D.
Pathological
Correct Answer
A. Inherited disorderExplanation
Dentin dysplasia type II is a hereditary condition that affects the development of dentin, a substance that makes up the majority of teeth. It is caused by genetic mutations that are passed down from parents to their children. This condition leads to abnormal dentin formation, which can result in weak and discolored teeth. Traumatic factors and pathological conditions are not known to be the cause of dentin dysplasia type II.Rate this question:
