(A). Syphilis
(B). Attrition
(C). Erosion
(D). Fluorosis


The maxillary central incisors in this image feature an unusual indentation which is characteristic of congenital syphilis. Those malformed incisors are called “screwdriver-shaped” incisors. Besides abnormal incisors, congenital syphilis can also form mulberry molars (molars with tiny globules instead of cusps).

  • Erosion describes tooth destruction from chemical influences (e.g., acid from purging, beverage, food). Affected teeth lose the enamel and become yellow (from dentin).
  • Attrition describes tooth destruction from forces between the teeth (e.g., grinding). Affected teeth have flat occlusal or incisal surface.
  • Fluorosis is caused by the over consumption of fluoride during tooth development. Affected teeth can appear mottled, pitted, and/or discolored.

Answer: (A). Syphilis

The dental hygiene board exams (NBDHE, NDHCE, CSCE) requires us to know medical conditions and their related oral side effects. Let’s quickly review a few more today and be productive!

  • Fetal alcohol syndrome: smooth philtrum (lack of a groove from the upper lip to the nose), micrognathia (small jaw)
  • Anemia: paleness of the oral tissues, ulcerations, glossitis (swollen, red, smooth tongue)
  • Cyclic neutropenia: severe periodontal disease (inflamed gingiva, attachment loss, bone loss, tooth mobility and tooth loss)
  • Marfan syndrome: high palate, narrow jaw, crowding of teeth, and malocclusion

This is a lot of information already but only the tip of the iceberg. With StudentRDH dental hygiene board exam review for the NDBHE/NDHCE, you can see medication conditions and their oral affects in bullet point format. We give you only what you need and eliminated the fluff. But be ready for the tough ride because there are lots of conditions that we need to know! You can do it, never underestimate yourself. #DHschool may not be easy, but know that there is light at the end of the tunnel!
