,CHAPTER 1 Understanding Dental Caries – From Pathogenesis to Prevention and Therapy
PART A: Multiple Choice Questions
Circle the letter of the single best answer. The answer and rationale are provided for each question.
1. Dental caries is most accurately described as:
A) A purely infectious disease caused solely by Streptococcus mutans
B) A multifactorial, biofilm-mediated, diet-modulated disease resulting in localized dissolution of tooth
mineral
C) A genetic disorder leading to structural enamel defects
D) An autoimmune condition triggered by oral bacterial antigens
Answer B
Rationale Caries is multifactorial — it requires a susceptible host, cariogenic microflora,
fermentable substrate, and time. No single bacterium exclusively causes the disease.
2. The 'caries balance' model conceptualizes caries as:
A) A permanent, irreversible process once demineralization begins
B) A dynamic equilibrium between pathological factors driving demineralization and protective factors
promoting remineralization
C) A bacterial infection requiring antibiotic treatment
D) A direct result of inadequate systemic fluoride intake
Answer B
Rationale The caries balance model, central to modern caries management, emphasizes that
lesion progression or regression depends on the net balance of protective versus
pathological factors at any given time.
3. Which of the following best represents a protective factor against dental caries?
A) Reduced salivary flow
B) Frequent fermentable carbohydrate consumption
C) Adequate saliva buffering capacity and fluoride exposure
D) High Streptococcus mutans counts in saliva
Answer C
Rationale Saliva buffers plaque acids and is supersaturated with calcium and phosphate at
neutral pH, promoting remineralization. Fluoride shifts the equilibrium further toward
remineralization.
4. Which statement best explains why dental caries is considered a public health priority?
A) It is only prevalent in developing countries with no access to fluoride
Test Bank | Understanding Dental Caries — Goldberg 1st Ed. | 19 Chapters
, B) It is the most prevalent chronic non-communicable disease globally, with significant social and
economic burdens
C) It exclusively affects children, making school-based programs the only required intervention
D) Effective treatments are unavailable, making prevention futile
Answer B
Rationale Untreated dental caries in permanent teeth affects approximately 2.5 billion people
worldwide and carries significant economic burden and impact on quality of life across
all age groups.
5. The concept of 'caries as a disease continuum' implies that:
A) Caries always progresses from enamel to pulp without the possibility of arrest
B) Caries lesions can be detected at early (pre-cavitation) stages and may be arrested or reversed
with appropriate intervention
C) Only cavitated lesions are clinically significant
D) Remineralization can fully regenerate cavitated dentin lesions
Answer B
Rationale Modern caries science recognizes that the disease exists on a spectrum. Early non-
cavitated lesions are amenable to non-operative management, underscoring the
importance of early detection.
PART B: True / False
Indicate True or False. Answer key and rationale are included in the table.
# Statement Answer Rationale

new medications causing
xerostomia, dietary changes)
can elevate risk at any point
in life.
3 Caries lesions can be arrested and made inactive True Altering the oral environment
through non-operative measures. (fluoride, diet modification,
improved oral hygiene) can
arrest lesion progression
and convert active lesions to
inactive ones.
4 Socioeconomic status is unrelated to caries prevalence. False Lower socioeconomic status
is consistently associated
with higher caries
prevalence due to limited
