Once bone is formed, it grows by:

 # Once bone is formed, it grows by:
 A. Interstitial growth only
B. Appositional growth only
C. Both appositional and interstitial growth
D. Degenerative changes into bony structures


The correct answer is B. Appositional growth only.

Which is growth by the addition of new layers on those previously formed. Bone formation begins in the embryo where mesenchymal cells differentiate into either fibrous membrane or cartilage. 

This leads to two paths of bone development:
1. Intramembranous ossification is so called because it takes place in membranes of connective tissue. Osteoprogenitor cells in the membrane differentiate into osteoblasts: a collagen matrix is formed which undergoes ossification. Note: The maxilla and mandible as well as the cranial vault are forrmed this way.

2. Endochondral ossification is how the remainder of the skeleton forms and takes place within
a hyaline cartilage model. Cartilage cells are replaced by bone cells (osteocytes replace chondrocytes), organic matrix is laid down and calcium and phosphate are deposited. This type of ossification
is principally responsible for the formation of short and long bones. Note: The ethmoid,
sphenoid, and occipital bones (bones of the cranial base) form this way.

The incisor overjet is increased for a class II case that is undergoing treatment. The reason is:

 # The incisor overjet is increased for a  class II case that is undergoing treatment. The reason is:
 A. Loss of anchorage
B. Arch collapse
C. Crowding in the lower arch
D. None of the above


The correct answer is A. Loss of anchorage.

Following are the features of anchorage loss in class II cases:
- Increase in overjet
- Molar relation  becoming more class II
- Normal canine relation without any change

Which of the following are typical and acceptable preventive and therapeutic measures for dealing with the periodontal problems during fixed appliance therapy?

 # Which of the following are typical and acceptable preventive and therapeutic measures for dealing with the periodontal problems during fixed appliance therapy?
 A. Elimination of gingivitis prior to placing orthodontic appliances
B. Home care instructions regarding the use of toothbrush and water pik during orthodontic treatment
C. Megavitamin therapy
D. Scaling and curettage immediately after appliance removal



The correct answer is A. Elimination of gingivitis prior to placing orthodontic appliances.


The mean value of visible plaque and visible inflammation showed significant increases during orthodontic treatment. Therefore, prior to orthodontic treatment, patients should have a high level of periodontal health and it should be maintained during the treatment period. Considering the relationship between orthodontic treatment and gingival health, patients, orthodontists and periodontists should cooperate during orthodontic treatment.

 # FDA approved locally delivered minocycline for subgingival placement is marketed under trade name:
 A. Periochip
B. Atridox
C. Arestin

The recommended concentration of acidulated phosphate (APF) fluoride gel is:

 # The recommended concentration of acidulated phosphate (APF) fluoride gel is:
 A. 2%
B. 8%
C. 1.23%
D. 10%


The correct answer is C. 1.23%.

Brudevold's solution or APF solution is prepared by dissolving 20 gms of NaF in 1 Litre (2% NaF) of 0.1M phosphoric acid and to this 50% hydro fluoric acid is added to adjust the pH at 3.0 and fluoride ion concentration at 1.23% APF gel is prepared by adding gelling agents like methylcellulose and hydroxyl ethyl cellulose and the pH is adjusted between 4-5.

Duraphat is:

 # Duraphat is:
 A. Lacquer
B. Sodium Fluoride in varnish form
C. Stannous Fluoride
D. Sodium Fluoride 2%


The correct answer is B. Sodium fluoride in varnish form.

Duraphat 50 mg/mL Dental Suspension is to be applied by the dental professional and not for self medication by the patient. 1 mL suspension contains 50 mg sodium fluoride (5% w/v), equivalent to 22,600 ppm fluoride ion (22.6 mg of fluoride) in an alcoholic solution of natural resins.

Recommended dosage for single application:
For primary teeth: up to 0.25 mL (= 5.65 mg fluoride)
For mixed dentition: up to 0.40 mL (= 9.04 mg fluoride)
For permanent dentition: up to 0.75 mL (= 16.95 mg fluoride)
For caries prevention: the application is usually repeated every 6 months but more frequent
applications (every 3 months) may be made.
For hypersensitivity: 2 or 3 applications should be made within a few days.
The patient should not brush the teeth or chew food for 4 hours after treatment.
Method of administration: For dental use.

Contraindications
  • Hypersensitivity to any ingredients of Duraphat.
  • Ulcerative gingivitis.
  • Stomatitis.
  • Bronchial asthma.

Special warnings and precautions for use
Application of Duraphat 50 mg/mL Dental Suspension to the whole dentition should not be carried out on an empty stomach. On the day when Duraphat has been applied, no high dose fluoride preparations, such as fluoride gels, should be used. The administration of fluoride supplements should be suspended for several days after applying Duraphat. Prolonged daily ingestion of excessive fluoride may result in varying degrees of fluorosis.

Interaction with other medicines and other forms of interaction
The presence of alcohol (33.8% v/v) in the Duraphat formula should be considered.

Fertility, pregnancy and lactation
As this product contains 33.8% v/v of ethanol (each dose contains up to 0.2 g of alcohol), it is recommended to avoid its use in pregnant women and during lactation.

Undesirable effects
Gastrointestinal disorders: Very rare (<1/10,000): Stomatitis, gingivitis ulcerative, retching, oedema mouth and nausea may occur in sensitive (allergic) individuals
- if necessary, the dental suspension layer can easily be removed from the mouth by brushing and rinsing.
Skin and subcutaneous tissue disorders: Very rare (<1/10,000): Irritation in sensitive individuals, angioedema
Immune System Disorders: Not known (cannot be estimated from the available data)

Hypersensitivity. Respiratory, thoracic and mediastinal disorders: Very rare/Isolated report (<1/10,000): Asthma

Overdose: Accidental ingestion of large amounts of fluoride may result in acute burning in the mouth and sore tongue. Nausea, vomiting and diarrhoea may soon occur after ingestion (within 30 minutes) and are accompanied by salivation, haematemesis, and epigastric cramping abdominal pain. These symptoms may persist for 24 hours. If less than 5 mg fluoride/kg body weight has been ingested, give calcium (eg milk) orally to relieve gastrointestinal symptoms and observe for medical assistance. For accidental ingestion of more than 15 mg fluoride/kg body weight, admit immediately to a hospital facility.

Length of junctional epithelium is:

 # Length of junctional epithelium is:
A. 0.25-1.35 mm
B. 0.5-0.75 mm
C. 1.0-2.0 mm
D. 1.0-1.5 mm


The correct answer is A. 0.25-1.35 mm.

Junctional Epithelium: The epithelium that attaches the gingiva to the tooth's surface, it consists of stratified squamous non-keratinizing epithelium. It is 3-4 layers thick in early life but the number of
layers increases with age to 10-20. It is thicker in the coronal portion but becomes thinner toward the cemento-enamel junction only a few cell layers. The length of the JE ranges from 0.25 to 1.35mm. 

Chronic atrophic candidiasis is commonly referred to as:

 # Chronic atrophic candidiasis is commonly referred to as:
 A. Oral Thrush
B. Denture stomatitis
C. Angular cheilitis
D. Erythema multiforme


The correct answer is B. Denture stomatitis.

Denture stomatitis should be mentioned because it is often classified as a form of erythematous candidiasis, and some authors may use the term chronic atrophic candidiasis synonymously. This condition is characterized by varying degrees of erythema, sometimes accompanied by petechial
hemorrhage, localized to the denture-bearing areas of a maxillary removable dental prosthesis. 

Although the clinical appearance can be striking, the process is rarely symptomatic. Usually, the patient admits to wearing the denture continuously, removing it only periodically to clean it. Whether this represents actual infection by C. albicans or is simply a tissue response by the host to the various microorganisms living beneath the denture remains controversial.

Stress shielding effect is seen in:

 # Stress shielding effect is seen in:
 A. Miniplates
B. Compression bone plating
C. Lag screw
D. Transosseous wiring


The correct answer is B. Compression bone plating.

Stress shielding is the reduction in bone density (osteopenia) as a result of removal of typical stress from the bone by an implant. This is because by Wolff's law, bone in a healthy person or animal remodels in response to the loads it is placed under. 

The most obvious postoperative complications of internal fixation using compression plates are misplaced bone segments or fixation devices. These complications are readily identified by clinical examination (e.g. malocclusion) or postoperative radiographic examinations. A second surgical procedure will correct such complications. Other complications related to rigid internal fixation include palpability, infection, extrusion or exposure, translocation, stress shielding, cortical osteopenia, and nonunion.

 # Which of the following drugs is likely to damage the eighth cranial nerve when administered for a long period of time ?
 A. Ethambutol
 B. Isoniazide
 C. Rifampicin
 D. Streptomycin


The correct answer is D. Streptomycin.

Nephrotoxicity, ototoxicity, and contact sensitization (due to this, topical application is not indicated) are common side effects of Streptomycin. 8th nerve is usually affected. Vestibular involvement is more common and cochlear involvement is less common. 

Which of the following structures is not of ectodermal origin?

 # Which of the following structures is not of ectodermal origin?
A. Hunter Schreger bands
B. Enamel spindles
C. Enamel tufts
D. Enamel lamellae

Malocclusion representing a transverse deficiency is often referred to as:

 # Malocclusion representing a transverse deficiency is often referred to as:
A. Open bite
B. Closed bite
C. Cross bite
D. Deep bite


The correct answer is C. Cross bite.

Patients with maxillary transverse deficiency usually have a narrow palate and a posterior crossbite. If the maxilla is narrow relative to the rest of the face, a diagnosis of transverse maxillary deficiency is justified. Occlusal relationships must be considered in all three planes of space. Lingual posterior crossbite (i.e., upper teeth lingual to lower teeth) is the major deviation from the normal transverse dental relationship and reflects deviations from ideal occlusion in the transverse plane of space.

Ref: Contemporary Orthodontics, William R. Proffit, 6th Edition.

Y shaped occlusal pattern is found in which teeth?

 # Y shaped occlusal pattern is found in which teeth?
A. Mandibular first premolar
B. Mandibular second premolar
C. Maxillary first premolar
D. Maxillary second premolar


The correct answer is B. Mandibular second premolar. 

The three cusp type mandibular second premolar manifests as a Y shaped occlusal pattern. The three-cusp type appears square lingual to the buccal cusp ridges when highly developed. Each cusp has well-formed triangular ridges separated by deep developmental grooves. These grooves converge in a central pit and form a Y shape on the occlusal surface. 

Y axis is used to analyze:

 # Y axis is used to analyze:
A. Maxillary growth
B. Mandibular growth
C. Both maxillary and mandibular growth
D. To design appliance


The correct answer is B. Mandibular growth.

Y-axis is obtained by joining the sella - gnathion line with the F.H. plane. The mean value is 59 degree with a range of 53 to 66 degree. The angle is larger in Class II Facial patterns than in patient exhibiting Class III pattern. In addition, Y axis indicates the growth pattern of the individual. If the angle is greater than normal, it indicates greater vertical growth of mandible. If the angle is smaller than normal, it indicates greater horizontal growth of mandible. 

Perikymata are the external surface manifestations of:

 # Perikymata are the external surface manifestations of:
A. Enamel rods
B. Incremental lines of Retzius
C. Nasmyth’s membrane
D. Pellicle



The correct answer is B. Incremental lines of Retzius.

The number of perikymata gradually decreases form cervical region to occlusal or incisal region because of undisturbed development of enamel prior to birth. Perikymata are usually absent in prenatally developed occlusal parts of deciduous teeth, whereas they are present in postnatal cervical parts. 

Abnormal function of epithelial chloride channel protein is the cause of:

 # Abnormal function of epithelial chloride channel protein is the cause of:
A. Ehlers Danlos Syndrome
B. Marfan Syndrome
C. Cystic fibrosis
D. Diabetes insipidus


The correct answer is C. Cystic fibrosis.

Cystic Fibrosis (Mucoviscidosis) Among the genetic paediatric disorders, cystis fibrosis is the most important. It is fundamentally a widespread disorder in epithelial transport affecting fluid secretion in exocrine glands and the epithelial lining of the respiratory, gastrointestinal, and reproductive tracts.

Cystic fibrosis follows simple autosomal recessive transmission. The primary defect is in the regulation of epithelial chloride transport by a chloride channel protein encoded by the cystic fibrosis gene. The impact of this defect in chloride transport differs in various tissues. 


Amyloidosis most commonly occurs in:

 # Amyloidosis most commonly occurs in:
A. Kidney
B. Spleen
C. Liver
D. Heart


The correct answer is A. Kidney.

Amyloidosis of the kidneys is most common and most serious because of ill effects on renal function. Kidneys affected by amyloidosis may be normal sized or enlarged; the cut surface is pale, waxy and translucent. Amyloidosis of spleen has two patterns - Sago spleen and lardaceous spleen. 

CSF rhinorrhea is found in:

 # CSF rhinorrhea is found in:
A. Frontal bone fracture
B. Zygomatico maxillary fracture
C. Nasoethmoidal fracture
D. Condylar fracture


The correct answer is C. Nasoethmoidal fracture.

CSF rhinorrhea is seen in nasoethmoidal, Le Fort II and Le Fort III fractures, associated with comminuted cibriform plate of ethmoid. Tramline effect and halo on pillow effect are diagnostic signs of CSF rhinorrhea. 


Wounds which are clean, uninfected and surgically incised, with edge of wounds approximated by sutures heal by:

 # Wounds which are clean, uninfected and surgically incised, with edge of wounds approximated by sutures heal by:
A. Primary intention
B. Secondary intention
C. Cauterization
D. All of the above


The correct answer is A. Primary intention.

Clean, uninfected, surgically incised wounds that are approximated by surgical sutures heal by primary intention. Infected, open large wounds that are not approximated by surgical sutures heal by secondary intention. Healing after flap surgery is by primary intention where as gingivectomy, gingivoplasty and extraction socket heal by secondary intention. 

Tensile strength of wound becomes normal after:

 # Tensile strength of wound becomes normal after:
A. 6 weeks
B. 4 month
C. 6 month
D. Never


The correct answer is D. Never.

Tensile strength of the scar is never equal to the original tissue, is always less (the maximum being 80% that of unwounded skin).

The best method of intubation for a child patient is:

 # A pediatric patient is brought to the clinic for interpositional arthroplasty procedure. The best method of intubation is:
A. Topical anesthesia and sedation
B. GA
C. Fibreoptic intubation
D. Tracheostomy



The correct answer is C. Fibreoptic intubation.

Nasal fibreoptic tube with cuffed endotracheal one size less than that is indicated for children is the best method. Airway management is either by oral airway or LMA. Inhalational induction should be done as paediatric patients cannot tolerate awake fibro-optic intubation. Usually uncuffed ETT are preferred in child patients.
