    • The student instrument<br />DCP (dental caries) <br />For all Dr. Kauser’s lectures and the 2 lectures of Dr. Nizam.<br />Write the correct answer.<br />
      • Dental plaque that develops over a long period of time becomes ………….
      • Fermentable carbohydrates are …………… that are easily metabolized by the bacteria present in our mouth to form acid compounds.
      • ……….. a type of complex carbohydrates are harmless because they are not digested in the mouth.
      • The plaque remains acid for some time, taking ……….. minutes to return to its normal pH.
      • ………… is most cariogenic sugar.
      Circle the correct answer.<br /> 1-Residual caries are:<br /> a.caries that are very deep to the dentin<br /> b. demeneralized tissue that are left in place before a filling is placed<br /> c. carious enamel that does not affect the dentin<br />2- Inactive lesions are:<br /> a. progressive<br /> b. arrested<br /> c. is not considered a carious lesion<br />3- Moderate challenge :<br /> a. Involves anterior teeth which are usually caries -free<br /> b. are on the occlusal part of the teeth<br /> c. are on the proximal surface of the posterior teeth.<br />4- Hyposalivation causes:<br /> a. rampant caries<br /> b. arrested caries<br /> c. multiple caries<br />5-ECC stands for and they are another name of nursing caries :<br /> a. early childhood caries<br /> b. early corrosive caries<br /> c. early cast caries<br />
      • This picture shows :

Calcium and Phosphates can again enter the tooth.<br />
      • During remenirelization

      • When eating low molecular carbohydrates
      13- Caries affect the tooth reaching to the dentin and pulp in a :<br />

      • triangular shape
      • straight
      14-_______________Is the deposition of mineral within the dentinal tubules and it requires the presence of a vital odontoblast .<br />
      • odontoclast
      • tubular sclerosis
      • active lesions of caries
      15-When lesions progress rapidly we get a<br />

      16-repetitve dentin is<br /> a. formation of new odontoblast<br /> b. destruction of odontoblast<br /> c. dentin formation<br /> <br />17- sudden inflammation of the pulp is called<br />
      • sudden pulpits
      • acute pulpitis
      • chronic pulpits
      18-chronic pulpitis is __________ and acute pulpitis is _________.<br />
      • Always painful, symptomless
      • Painful, is sharply painful
      • Symptomless, always painful
      19- We use radiographs to :<br />
      • Diagnose caries in the dentin
      • Diagnose caries on the proximal areas of the enamel
      • All of the above.
      20-In pulpitis if pain persists for minutes or hours after removal of the stimulus it indicates<br />a. reversable pulpitis<br />b. irreversable pulpitis<br />c. pulpitis<br />21-The tooth is tender to bite on and tender to touch because it acts as a piston in its socket, transmitting forces directly to the inflamed periapical tissues.<br />a. periapical inflamation<br />b. periodontal inflamation<br />c. pulp inflammation<br />22-Clinically, actively progressing lesions are :<br />a. mat and hard<br />b. soft and wet<br />c. shiny and hard<br />23- This is primary caries next to a filling, caused by the biofilm at the tooth surface or the surface of any cavity. <br />
      • Secondary caries
      • Residual caries
      • Primary caries
      24.________ forms the basis for treatment decision.<br /> a. prognosis<br /> b. prevention<br /> c. diagnosis<br />25. D3 indicates lesions into:<br />a. pulp<br />b. dentin<br />c. enamel<br />26. Sharp probes should never be used to detect :<br />a. the feel of early cavitations<br />b. suspicious carious lesions<br />c. the superficial caries<br />27. _______ are hard and are often located in a plaque free area coronal to the gingival margin and may be cavitated.<br />a. active lesion<br />b. arrested lesion<br />c. secondary caries<br />28- Root surface lesions tend to spread ______ and combine with minor neighboring lesions and may thus eventually encircle the tooth.<br />
      • Laterally
      • Occlusaly
      • apically
      29- The lesion visible on a wet surface is all the way through ___________________<br />
      • enamel

      30- To avoid missing micro-caries we use:<br /> a. bitewing radiographs<br /> b. X-ray radio graph<br /> c. DIFOTI<br />31- Hidden caries are:<br />
      • Micro-carise
      • missed during visual examination but found on radiographs

FOTI<br /> b. DIFOTI<br /> c.infrared thermography <br />34- caries at the margin of a restoration:<br /> a. secondary caries <br /> b. primary caries<br /> c. residual caries<br />35- Recurrent caries usually occurs _______and ________ in areas of plaque stagnation .<br />
      • Approximally , cervically
      • Apically , occlusaly
      • Apically, approximally
      36- Ditching is:<br />
      • When the restoration is broken
      • When the margins of the amalgam are fractured
      • When the tooth is extracted
      <br />37- Sometime a __________ on radiograph indicates residual caries left when the restoration was placed .<br />
      • Radiolucency
      • Radiograph image
      • Radiodense
      38- Plaque and bacteria with simple sugar produce acid and is in the <br /> a. demenerlization stage<br /> b. reminarlization stage<br /> c. acidic stage<br />True or fales:<br />
      • Dental caries is a chronic infectious disease that involves the demineralization of the mineralized tissues of teeth by acids produced by metabolism of dietary carbohydrates by plaque micro-organisms, but is influenced by fluoride and other factors. ( )
      • If the enamel is worn off (damaged) by the dental caries the next part to get affected is the cementum. ( )
      • The tooth is sensitive and we can’t bite down on tooth when the caries are on the enamel. ( )
      • Epidemiology is the study of health and disease states in individuals rather than populations. ( )
      • People who are financially poor and those who live in rural areas are more prone to caries than other people. ( )
      • When naming caries we start with the severity then the anatomical site and then the status of the lesion. ( )
      • primary lesion begins on a surface with no previous lesion or restoration.
      • Moderate caries are the least in severity.
      • GV black classification of caries lesions,Class 3 is Proximal surfaces on anterior teeth.
      • The mount and hume classification for dental caries involves the size and the severity.
      • Dental caries are reversible.
      • Acidic foods/drinks do cause caries on their own .
      • Xerostomia means dry mouth and it can cause caries.
      • When the pH is more than 6.5 the stage is favouring to demeneralization.
      • Saliva Saturated in calcium and phosphate ions causes caries.
      • The tooth is continuously bathed with fluoride in the enamel and dentin..
