1A 28-year-old patient presents with a deep occlusal carious lesion on a mandibular first molar. After caries removal, a small pinpoint pulp exposure occurs in a young, asymptomatic, vital tooth with no pre-operative pain. What is the most appropriate immediate management?

A.Immediate root canal therapy

B.Direct pulp cap with a calcium silicate (e.g. MTA) or calcium hydroxide material

C.Extraction of the tooth

D.Place a sedative dressing and review in six months with no capping material

Explanation: A small mechanical exposure in a young, vital, asymptomatic tooth with adequate isolation is the classic indication for direct pulp capping. Calcium silicate cements (MTA, Biodentine) or calcium hydroxide stimulate reparative dentine bridge formation, preserving pulp vitality.

2Which cavity classification, according to G.V. Black, describes a carious lesion located in the pit and fissure of an occlusal surface of a posterior tooth?

A.Class II

B.Class III

C.Class I

D.Class V

Explanation: Class I cavities involve pits and fissures: occlusal surfaces of premolars/molars, the buccal/lingual pits of molars, and the palatal pit of incisors. Recognising Black's classification underpins restorative treatment planning.

3A patient reports sharp pain to cold that lasts only a few seconds and disappears immediately once the stimulus is removed. There is no spontaneous pain and no tenderness to percussion. Which diagnosis best fits this presentation?

A.Symptomatic irreversible pulpitis

B.Acute apical abscess

C.Pulp necrosis

D.Reversible pulpitis

Explanation: Reversible pulpitis is characterised by a sharp pain to thermal stimuli that resolves quickly once the stimulus is removed, with no lingering or spontaneous pain. Removing the irritant (e.g. caries) typically allows the pulp to recover.

4During root canal treatment of a maxillary central incisor, the working length should ideally terminate at which anatomical landmark?

A.The apical constriction, approximately 0.5-1 mm short of the radiographic apex

B.Exactly at the radiographic apex

C.1-2 mm beyond the radiographic apex into the periapical tissues

D.At the cementoenamel junction

Explanation: The apical constriction (minor diameter) is the narrowest part of the canal and the junction of pulp and periodontal tissue, usually 0.5-1 mm short of the radiographic apex. Terminating instrumentation and obturation here optimises healing and avoids over-extension.

5A 35-year-old presents with a fractured maxillary lateral incisor that requires a full-coverage crown. Which finish line (margin) design is most appropriate when maximising preservation of tooth structure while still allowing a defined margin for an all-ceramic restoration?

A.Feather-edge (knife-edge) margin

B.Chamfer or shoulder margin

C.Bevelled shoulder with 2 mm reduction

D.No margin preparation (supragingival butt)

Explanation: A chamfer or shoulder provides a clearly defined finish line that supports ceramic bulk and marginal seal while being conservative. A shoulder/chamfer is preferred for all-ceramic crowns to provide adequate material thickness and resistance to fracture.

6When etching enamel with 37% phosphoric acid prior to placement of a resin composite restoration, what is the principal purpose of the etching step?

A.To chemically bond the composite to calcium ions

B.To disinfect and kill all remaining bacteria in the cavity

C.To create surface micro-porosities for micromechanical resin tag retention

D.To remineralise the demineralised dentine

Explanation: Phosphoric acid etching of enamel removes the smear layer and selectively dissolves hydroxyapatite, creating a micro-rough surface into which resin flows to form resin tags, achieving micromechanical retention. This is the basis of adhesive bonding.

7A patient who is at high caries risk and has poor access to dental care presents with a cavitated lesion in a primary molar. Which restorative material is particularly indicated because it releases fluoride and chemically bonds to tooth structure?

A.Resin composite

B.Dental amalgam

C.Gold inlay

D.Glass ionomer cement

Explanation: Glass ionomer cement (GIC) chemically bonds to enamel and dentine and releases fluoride, helping to inhibit secondary caries. This makes it valuable in high-caries-risk patients and in atraumatic restorative treatment (ART), which is widely used in South African public health settings.

8A patient presents with a periapical radiolucency at the apex of a non-vital tooth that does not respond to pulp testing. The lesion is well-circumscribed, asymptomatic, and approximately 8 mm in diameter. Initial management of a suspected periapical (radicular) lesion of pulpal origin should be:

A.Non-surgical root canal therapy

B.Immediate surgical enucleation without endodontics

C.Antibiotics alone for two weeks

D.Extraction and biopsy of all such lesions

Explanation: Most periapical radiolucencies associated with a non-vital tooth are inflammatory (periapical granuloma or radicular cyst) and respond to non-surgical root canal therapy, which removes the source of irritation and allows healing. Surgery or biopsy is reserved for lesions that fail to heal or have atypical features.

9Which of the following is the most appropriate intracanal medicament to place between endodontic appointments for its antibacterial effect against a wide range of root canal pathogens?

A.Formocresol

B.Calcium hydroxide paste

C.Sodium fluoride gel

D.Zinc oxide eugenol as a permanent fill

Explanation: Calcium hydroxide is the most widely used interappointment intracanal medicament. Its high pH (around 12.5) is antibacterial and helps dissolve necrotic tissue, making it effective against most root canal pathogens while being well tolerated by periapical tissues.

10A 16-year-old sustains a complicated crown fracture of an immature maxillary central incisor with an open apex and pulp exposure. The pulp is vital and the patient presents within hours. Which procedure best preserves continued root development?

A.Conventional pulpectomy and root canal filling

B.Extraction and immediate implant placement

C.Partial pulpotomy (Cvek pulpotomy) with a calcium silicate dressing

D.Pulp capping with zinc oxide eugenol only

Explanation: In a vital immature tooth with an open apex, a partial (Cvek) pulpotomy removes the inflamed superficial pulp and preserves the remaining vital radicular pulp, allowing continued root development (apexogenesis). A calcium silicate dressing promotes a dentine bridge.

About the HPCSA Dental Board Exam Exam

The HPCSA Board Examination is a registration assessment for foreign-qualified dentists wishing to practise in South Africa, administered under section 25 of the Health Professions Act 56 of 1974. It comprises a written multiple-choice paper (75 clinical and 25 ethics/legal items, no negative marking) and a practical OSCE/OSPE, benchmarked to the South African BChD/BDS final examinations.

Assessment

Written paper of 100 single-best-answer MCQs (75 clinical + 25 ethics/legal), followed by a practical OSCE/OSPE of at least 13 clinical stations for candidates who pass both written components.

Time Limit

2 hours for the online written examination; the practical examination is held separately within roughly 10-14 days.

Passing Score

50% required separately in each written component (clinical and ethics/legal); both must be passed to be admitted to the practical examination.

Exam Fee

Historically R3 300 examination fee (adjusted from time to time by the HPCSA); a R500 re-administration fee applies for non-attendance. Verify the current fee with the HPCSA. (Health Professions Council of South Africa (HPCSA), Medical and Dental Professions Board)

HPCSA Dental Board Exam Study Tips from Top Performers

1Master the HPCSA Guidelines for Good Practice booklets, the Ethical Rules of Conduct (GNR 717), the Health Professions Act 56 of 1974 and the National Health Act 61 of 2003 - the 25 ethics/legal items are scored separately and must be passed in their own right.

2Focus clinical revision on the South African disease burden and BChD/BDS finals standard: HIV oral manifestations, noma, necrotising periodontal disease, early childhood caries, minimally invasive caries management and ART, and managing medically compromised patients.

3Practise applied clinical reasoning and OSCE-style stations, not just recall, since the practical examination assesses diagnosis, treatment planning, local anaesthesia, exodontia and emergency management under observation.

Frequently Asked Questions

How is the HPCSA dental board exam structured?

It has a written multiple-choice paper of 100 single-best-answer items (75 testing clinical knowledge and 25 testing ethics and legal knowledge) with no negative marking, set in English over 2 hours, followed by a practical OSCE/OSPE of at least 13 stations for candidates who pass both written components.

What is the pass mark and how many attempts are allowed?

Candidates must score at least 50% separately in each written component (clinical and ethics/legal) to be admitted to the practical examination. The Board permits a maximum of three attempts within two years to complete the examination.

What do I need before sitting the HPCSA dental board exam?

Foreign-qualified dentists need SAQA evaluation of their qualification for equivalence, credential verification (e.g. ECFMG/EICS), a certificate of good standing, English proficiency where the qualification was not in English, and a letter of endorsement from the National Department of Health, before the Medical and Dental Professions Board confirms eligibility.

When and where is the examination held?

The Board examination is usually held twice a year (around March/April and October/November). The written examination is offered at predetermined centres, and the practical examination is conducted at a South African faculty of health sciences contracted by the Board.
