Tic douloureux is synonymous with:

 # Tic douloureux is synonymous with:

A. Trigeminal neuralgia

B. Temporal lobe epilepsy

C. Glossopharyngeal neuralgia

D. Todds paralysis

The correct answer is A. Trigeminal neuralgia.

Trigeminal neuralgia (TN or TGN), also called Fothergill disease, tic douloureux, or trifacial neuralgia is a long-term pain disorder that affects the trigeminal nerve, the nerve responsible for sensation in the face and motor functions such as biting and chewing. It is a form of neuropathic pain. There are two main types: typical and atypical trigeminal neuralgia. The typical form results in episodes of severe, sudden, shock-like pain in one side of the face that lasts for seconds to a few minutes. Groups of these episodes can occur over a few hours. The atypical form results in a constant burning pain that is less severe. Episodes may be triggered by any touch to the face. Both forms may occur in the same person. It is regarded as one of the most painful disorders known to medicine and often results in depression.

First to classify malocclusion on structural basis:

 # First to classify malocclusion on structural basis:

A. Salzmann

B. Kingsley

C. Angle

D. Katz

The correct answer is A. Salzmann.

Salzmann in 1950 was the first to classify malocclusion based on skeletal structures. 

• Skeletal Class I: These are purely dental malocclusions. The jaws are in harmony with one another. The profile is orthognathic. 

• Skeletal Class II: Subnormal and distal mandibular development in relation to maxilla 

• Skeletal Class III: Overgrowth of the mandible with a prognathic mandible. 

Indications of Hydroxyapatite coated implants over titanium or metal-surfaced implants include all of the following except

 # Indications of Hydroxyapatite coated implants over titanium or metal-surfaced implants include all of the following except?

A. The need for greater bone-implant interface contact area

B. The ability to place the implant in type I bone

C. Fresh extraction sites

D. Newly grafted sites

The correct answer is B. The ability to place the implant in type I bone. 

Indications of HA-coated implants over titanium- or metal-surfaced implants include: 

• Need of more contact area at bone-implant interface 

• Implant can be given in type IV bone 

• Implant can be given at fresh extraction sites 

• Implant can be given at newly grafted sites 

Surfactant is secreted by:

 # Surfactant is secreted by:

A. Pneumocyte I

B. Pneumocyte II

C. Goblet cells

D. Pulmonary vessels

The correct answer is B. Pneumocyte II.

Surfactant lowers the surface tension of the fluid lining of the alveoli and prevents the collapsing tendency of the lungs. It is a phospholipid. The absence of surfactant results in Hyaline membrane disease (or) respiratory distress syndrome. 

Scleroderma is associated with:

 # Scleroderma is associated with:

A. Parry Romberg Syndrome

B. Pierre Robin Syndrome

C. Gardner Syndrome

D. Peutz Jegher Syndrome

The correct answer is A. Parry Romberg Syndrome.

Hemifacial atrophy or Parry Romberg syndrome consists of slow progressive atrophy of soft tissues of essentially half the face, characterized by progressive wasting of subcutaneous fat, accompanied by atrophy of skin, cartilage, bone, and muscle. This syndrome is accompanied usually by contralateral Jacksonian epilepsy, trigeminal neuralgia, and changes in hair and eyes. It is also reported that hemifacial atrophy is a form of localized scleroderma which is supported by its concurrence with scleroderma.

Some Sample Intraoral Photograph in Orthodontics

 Intraoral photography involves capturing a series of detailed images of the inside of a patient's mouth to document their oral health, aid in diagnosis, and monitor treatment progress. To provide a comprehensive view of the patient's oral structures, several different views or types of intraoral photographs are commonly taken. These views offer orthodontists and other dental professionals a well-rounded understanding of the patient's dental condition. Here are some of the most common views included in intraoral photography: 

Frontal View (Full-Arch View): This view captures the entire arch of teeth from the front, providing a comprehensive overview of tooth alignment, spacing, and symmetry. It helps orthodontists assess the overall aesthetics of the smile and identify any irregularities. 

Right Lateral View: The right lateral view is taken from the side to evaluate the profile of the teeth and jaws from the right angle. This view is essential for diagnosing issues like overbites, underbites, and jaw discrepancies.

Left Lateral View: Similar to the right lateral view, the left lateral view provides a profile perspective from the left side. It aids in assessing the relationship between the upper and lower jaws and identifying any asymmetries.

Upper Occlusal View: The upper occlusal view captures the biting surfaces of the upper teeth when the patient bites down. It helps orthodontists evaluate the alignment of upper teeth, spacing, and the overall occlusal relationship.

Lower Occlusal View: Similar to the upper occlusal view, the lower occlusal view focuses on the biting surfaces of the lower teeth. This view assists in evaluating lower arch alignment, spacing, and occlusal considerations.

These five specific views are crucial for orthodontists to accurately diagnose dental conditions, plan appropriate treatments, and monitor progress throughout the orthodontic journey.
