LESSON 2: DENTAL CARIES Flashcards
According to ________, dental caries is an infectious microbiological disease of the teeth that results in localized dissolution and destruction of calcified tissues.
Sturdevant
According to ________, dental caries are localized post eruptive pathological process of external origin involving softening of the heard tooth tissue and preceding to the formation.
World Health Organization (WHO)
(Hindi masisira ang ngipin unless erupted. Hanggat hindi na expose sa bacterial environment hindi siya masisira.)
According to ________, dental caries are microbial disease of the calcified tissues of the teeth, characterized by demineralization of the inorganic portion and destruction of the organic substance of the tooth

What are the classification of caries?
- Based on Anatomical Site
- Based on Progression
- Based on the virginity of the lesion
- Based on Extend of Caries
- Based on the Direction of the Attack
- Based on the Number of Surfaces Involved
- Based on Chronology
- G.V. Black Classification
- Based on Tissue Involved
- WHO Classification
- Other Classification
- Classification according to Mc Ghee
Anatomical Site Classification and Definition
- Pit and Fissure Caries - Occlusal on Posterior, Buccal/Lingual on Upper Incisors
- Smooth Surface Caries - Proximal, Buccal, Lingual Surface
- Root Caries - CEJ, Structures below gingiva
- Interproximal Caries - Mesial side co-incise with the distal side (Two teeth involved)
Caries Based on Progression
- Acute - Rapid
- Chronic - Long standing lesions
Types of Acute Progression
- Rampant Caries
- Nursing Bottle Caries
- Radiation Caries
These caries are rapidly invading and involves several teeth. Its lesions are soft and light colored. Pulp is already involved at early stage.
Acute Progression
These caries under Acute Progression are suddenly appearing and widespread. It results in early involvement of the pulp.
Rampant Caries
Nursing Bottle Caries are also known as?
- Nursing Caries
- Nursing Bottle Mouth
- Nursing Bottle Syndrome
- Bottle Propping Caries
- Comforter Caries
- Baby Bottle Tooth Decay
- Tooth Cleaning Neglect
- Maternally Derived Streptococcus Mutans Disease or MDSMD (New Name)
Radiotherapy is associated with the dryness of the mouth or ________ due to decreased salivary secretion.
Xerostomia
These caries are caused by decreased salivation from radiotherapy.
Radiation Caries
These caries which fall under the category of based on progression involve lesions that are long standing, fewer in number, and smaller than the acute lesions.
Chronic Caries
Decalcified dentin is ________ and ________.
Dark brown and Leathery
Type of Chronic Caries
Arrested Caries
These caries are stationary and does not show any tendency for further progression due to the reparative dentin which forms in response to the stimulus of the caries.
Arrested Caries
Categories under Virginity of the Lesion
- Initial/Primary Caries
- Secondary/Recurrent Caries
It is the first attack on the tooth surface. Its designation is based on the initial location of the lesion on the surface rather than the extent of the damage.
Initial/Primary Caries
These are observed around the edges and under the restorations.
Secondary/Recurrent Caries
Common Locations of Secondary/Recurrent Caries
- Rough or overhanging margin
- Fracture place in all locations of the mouth.
Reasons why secondary/recurrent cavities occur.
- Not all caries have been removed during cavity prep.
- Cavity was not sealed properly, allowing bacteria to enter that space.
Classification based on Extend of Caries
- Incipient Caries
- Occult Caries
- Cavitated Caries

These are early caries lesions that are best seen on smooth surfaces of the teeth. They are visible as white spots.
Incipient Caries
Incipient Caries undergo the process of ______ which indicates that the lesion is not for restorative treatment.
Remineralization
These are caries found in dentin but no visible damage on the enamel. It is defined as hidden caries and can only be seen through radiographs or transillumination.
Occult Caries
