Does the PRC Dentists Licensure Examination exist?

Yes. PRC publishes official programs and results for the Dentists Licensure Examination, and RA 9484 requires licensure examination and registration for the practice of dentistry in the Philippines.

Who administers the exam?

The exam is administered by the Professional Regulation Commission through the Professional Regulatory Board of Dentistry.

What is the passing score?

RA 9484 states that the licensure examination consists of written and practical tests and requires a general weighted average of at least 75%, with no rating below 50% in any subject.

How many questions are on the exam?

A single total item count is not published in the public PRC program. The PRC written program publishes subject blocks and weights; the 2023 enhanced TOS uses 100-item specification tables for written subjects.

What subjects are covered in the written phase?

The May 2026 written program lists general and oral anatomy and physiology; pathology, microscopic anatomy, embryology and microbiology; restorative and community dentistry; prosthodontics and dental materials; roentgenology, oral diagnosis and oral surgery; anesthesiology and pharmacology; pediatric dentistry and orthodontics; jurisprudence, ethics and practice management; and periodontics and endodontics.

What is tested in the practical phase?

The May 2026 revised practical program includes Class II and Class I cavity preparations, preparation of two abutments for a porcelain-fused-to-metal fixed partial denture, removable partial denture design, and complete denture procedures.

How do I verify filing dates, fees, and room assignments?

Use PRC Online Services and the PRC schedule, downloads, and room assignment pages for the current administration. PRC programs instruct examinees to verify school/building assignments on the official PRC website.

Which statement best explains why cavitated enamel cannot biologically regenerate like dentin can continue forming?

Cementoblasts replace ameloblasts on the crown after eruption

Dentin has no living cells and therefore cannot respond

Enamel contains blood vessels that thrombose after eruption

Ameloblasts are lost after enamel formation, while odontoblasts remain along the pulp

1During tooth development, which sequence correctly describes the early morphologic stages of the enamel organ?

A.Bud stage, cap stage, bell stage

B.Bell stage, bud stage, cap stage

C.Apposition stage, bud stage, cap stage

D.Calcification stage, bell stage, bud stage

Explanation: The enamel organ progresses from bud to cap to bell before apposition and calcification. This order helps connect developmental disturbances to the stage in which enamel, dentin, and crown shape are being established.

2Which cells are directly responsible for forming enamel?

A.Ameloblasts

B.Odontoblasts

C.Cementoblasts

D.Fibroblasts

Explanation: Ameloblasts form enamel and are lost after tooth eruption, which is why mature enamel has no cellular repair mechanism. Odontoblasts remain along the pulp and continue dentin formation.

3Which major salivary gland is located anterior and inferior to the ear and drains through Stensen duct opposite the maxillary second molar?

A.Parotid gland

B.Submandibular gland

C.Sublingual gland

D.Minor palatal gland

Explanation: The parotid gland drains through Stensen duct, which opens on the buccal mucosa near the maxillary second molar. This landmark is important when evaluating salivary flow and parotid duct trauma.

4How many primary teeth are normally present in a complete deciduous dentition?

A.20

B.24

C.28

D.32

Explanation: A complete primary dentition has 20 teeth: two incisors, one canine, and two molars in each quadrant. Premolars are not present in the primary dentition.

5The mandibular canal primarily transmits which neurovascular bundle?

A.Inferior alveolar nerve, artery, and vein

B.Greater palatine nerve and vessels

C.Nasopalatine nerve and vessels

D.Posterior superior alveolar nerve and vessels

Explanation: The mandibular canal carries the inferior alveolar nerve and vessels through the mandible. Its location matters in implant planning, third molar surgery, and interpreting mandibular radiographs.

6Which root arrangement is most characteristic of a permanent maxillary first molar?

A.Two buccal roots and one palatal root

B.One buccal root and one lingual root

C.One conical root

D.Two mesial roots and two distal roots

Explanation: The maxillary first molar usually has mesiobuccal, distobuccal, and palatal roots. This three-root pattern is central to extraction planning, endodontic access, and furcation assessment.

7The curve of Spee describes which occlusal relationship?

A.The anteroposterior curvature of the mandibular occlusal plane

B.The transverse curvature from buccal to lingual cusps

C.The vertical overlap of anterior teeth

D.The mesiodistal contact relationship between adjacent teeth

Explanation: The curve of Spee is the anteroposterior curve seen when viewing the mandibular arch from the side. The transverse buccolingual curve is the curve of Wilson.

8Which function is correctly associated with the periodontal ligament?

A.Shock absorption, proprioception, and tooth support

B.Enamel repair after eruption

C.Production of saliva for buffering

D.Formation of the oral vestibule

Explanation: The periodontal ligament suspends the tooth in alveolar bone, absorbs occlusal forces, and provides proprioceptive feedback. These functions explain mobility changes in trauma and periodontal disease.

9Sensation from most mandibular teeth reaches the trigeminal nerve through which branch?

A.Mandibular division via the inferior alveolar nerve

B.Ophthalmic division via the nasociliary nerve

C.Maxillary division via the infraorbital nerve

D.Facial nerve via the chorda tympani

Explanation: The inferior alveolar nerve is a branch of V3, the mandibular division of the trigeminal nerve. It supplies sensory innervation to mandibular teeth before emerging as the mental nerve.

10Hertwig epithelial root sheath is most directly involved in which process?

A.Initiating root shape and root dentin formation

B.Depositing mature enamel on the crown

C.Forming the oral mucosal epithelium

D.Producing the periodontal ligament collagen fibers

Explanation: Hertwig epithelial root sheath guides root formation and signals odontoblast differentiation for root dentin. Disruption of this structure can contribute to abnormal root morphology.
