On replantation of an avulsed tooth, which type of resorption is most commonly observed
1) Surface resorption / External resorption
2) Internal resorption
3) Inflammatory resorption
4) Replacement resorption
ADC Test Answer: 4
After replantation of an avulsed tooth, the periodontal ligament cells are often damaged. When these cells fail to regenerate properly, the root surface fuses directly with alveolar bone. This leads to replacement resorption (ankylosis), where the tooth structure is gradually substituted by bone.

Anatomy Answer: 4The nerve to masseter passes through the mandibular notch to enter the muscle on its medial surface
What causes clasp breakage in removable partial dentures
(RPD)?
1) Excessive force
2) Work hardening
3) Poor design
4) Material fatigue
Clasp breakage in removable partial dentures (RPDs) is often attributed to work hardening of the metal used in the clasps. Work hardening occurs when the metal is subjected to repeated stress, causing it to become more brittle and less ductile. This increased brittleness can lead to fractures under normal functional loads, making proper design and material selection critical in RPD construction.
The most appropriate management for a child with a primary tooth that caused a
severe, throbbing toothache the previous night is to
1) prescribe an analgesics.
2) perform a pulpectomy
3) remove caries and place a temporary restoration.

Pulpectomy removes necrotic or infected pulp tissue, resolving pain while preserving the tooth's functionality.
In partial dentures, guiding planes serve to:
1) Aid in balancing occlusion
2) Ensure predictable clasp retention

Guiding planes provide a surface to help achieve reliable clasp retention, essential for the stability and effectiveness of partial dentures.
Following extraction of the molar teeth, which statement is correct?
1) The ridge height is lost more from the maxilla than from the mandible.
2) The maxillary ridge will get more bone lost from the palatal aspect than the buccal.
3) The mandibular arch is relatively narrower than the maxillary arch.
4) Compared with the pre-resorption state, the mandibular ridge will lose more bone from the lingual aspect than the buccal one.
ADC Test Answer: 2
After molar extraction, the maxillary ridge tends to lose more bone from the palatal aspect due to the direction of the resorptive forces and the presence of the palatal blood vessels and nerves.

Of the following, the most difficult impaction to extract is:
1) Mesioangular
2) Vertical
3) Distoangular
4) Horizontal
Distoangular impactions of mandibular molars are often considered the most challenging to extract due to their position and the amount of bone that must be removed to access the tooth. The angulation of the tooth can complicate the extraction process, requiring more extensive surgical intervention. Additionally, the removal of bone in this area can weaken the ramus of the mandible, increasing the risk of fracture during extraction.
Which soft palate muscle is not affected by a laceration of the mucosa
1 cm lingual to the 2nd maxillary molar?
1) Tensor veli palatini
2) Palatoglossus
3) Palatopharyngeus

A laceration of the mucosa 1 cm lingual to the 2nd maxillary molar is unlikely to damage the levator veli palatini as it is located above the palatoglossal fold.
Premature exfoliation of primary mandibular canine is most often the sequelae of:
1) Caries
2) Trauma
3) Serial tooth extraction
4) Arch length inadequacy
SOLUTION The two major symptoms of severe crowding in the early mixed dentition are severe irregularity of the erupting permanent incisors and early loss of primary canines caused by eruption of the permanent lateral incisors.
After a definitive analysis of the profile and incisor position, these patients face the same decision as those with moderate crowding; whether to expand the arches or extract permanent teeth. In the presence of severe crowding, limited treatment of the problem will not be sufficient and permanent tooth extraction is most likely the best alternative.

The basic principle of Orthodontic spot welder lies on the concept of :-
1 Heat technique
2) Quenching
3) Diodelasers
4) Electrode Technique
SOLUTION The type of welding used to join Orthodontic components is called Spot welding.
1. Transmit current to the metals to be joined so as to cause a rapid increase in temperature.
