Oral Microbiology and Plaque-associated Diseases

Lactobacillus acidophilus

They do not have effective attachment mechanisms to allow them to accumulate in plaque that develops over noncarious teeth.

Prepubertal Periodontitis

Type of periodontitis occurring in those with primary teeth.

Dental plaque

A microbial mass that accumulates on the teeth in the absence of oral hygiene or may result from the impaction of bacteria and food in the non-self-cleansing areas of the dentition.

Lactobacillus acidophilus

More important in the progression of a carious lesion after other bacteria have initiated tooth destruction. Acidogenic and aciduric.

Calculus

hardened material resulting from the mineralization of dental plaque.

Pulpitis

Inflammation of the pulp caused by untreated carious lesion progressing and approaching the tooth pulp.

Strep mutans and anaerobes

With teeth eruption, new bacteria such as __ appear and _ increase in number.

Actinomyces naeslundi

Good plaque formers and can accumulate to high numbers in plaque. Important in root caries formation.

Pellicle

A thin proteinaceous layer that coats all tooth surfaces exposed to saliva.

Streptococcus mutans

They are important plaque formers and can accumulate rapidly in plaque in the presence of sucrose.

normal microbiota

consists mostly of bacteria, although about 1/3 of the population also has the yeast, Candida albicans in their mouth.

Periodontitis

This disease process affects both the gums and the bone in which the teeth are set; irreversible.

Necrotizing Ulcerative Gingivitis

Also called Trench Mouth,

Necrotizing Ulcerative Gingivitis

associated with plaque accumulation, and the predisposing factor is stress; reversible if plaque accumulation is controlled.

Chronic Periodontitis

slowly progressing destruction of bone in which the teeth are set that occurs over a period of years. Most common form that usually occurs in persons older than 35 years old.

Rapidly Progressive Periodontitis

Type of periodontitis most commonly seen in those younger than age 35 years.

Simple or Acute Gingivitis

Disease process that only affects the gingival tissue resulting in swelling, redness, and maybe spontaneous bleeding.

Cellulitis

A condition where the surrounding facial tissues may become red and swollen due to an infection from a diseased tooth.

Juvenile Periodontitis.
