Coursework

  • Biology with labrequireddiffers

    5 semesters · 20 credits · lab

    Most dental schools ask for 2 semesters · 8 credits · lab.

    "Biological Sciences - Complete a minimum of 20 semester credit hours (13 of those credit hours must include these)": anatomy or histology with labs, physiology, microbiology or immunology, and cell biology, biochemistry, or molecular biology. IUSD names no introductory biology sequence; it counts a large total instead, with the named upper level courses carried on their own lines here. Laboratory is specified for the anatomy or histology portion.

  • General chemistry with labrequired

    2 semesters · 8 credits · lab

    Two semesters with lab. The DAT's general chemistry section assumes the full sequence.

  • Organic chemistry with labrequireddiffers

    1 semester · 4 credits · lab

    Most dental schools ask for 2 semesters · 8 credits · lab.

    "Organic Chemistry with lab (4 cr hrs)", one semester rather than the usual two, inside a chemistry bucket of at least 12 hours.

  • Biochemistryrequired

    1 semester · 3 credits

    "Cell Biology, Biochemistry, or Molecular biology (3 cr hors)" [sic]. The three hour slot is required, but biochemistry is only one of three courses that fill it, so cell biology or molecular biology answers it equally.

  • Physics with labrequired

    2 semesters · 8 credits · lab

    Two semesters, algebra-based accepted essentially everywhere. A handful of schools want only one semester; the two-semester plan covers them all.

  • English or writing-intensivenot required here

    IUSD names no English requirement. "English Composition" appears only as one of five ways to fill the 3 hour humanities block, beside history, literature, philosophy and foreign language, and that block is carried on the social sciences and humanities line.

  • Anatomy and physiologyrequireddiffers

    7 credits · lab

    Most dental schools ask for 3 credits and list it as recommended.

    "Anatomy or Histology with labs - Human, Mammalian, or Comparative (4 cr hrs)" plus "Physiology - Human, Mammalian, or Cell (3 cr hrs)", which is 7 hours taken separately. IUSD adds: "If Anatomy and Physiology are combined, must complete A/P I / II with labs (8 cr hrs)." Histology substitutes for anatomy.

  • Microbiologyrequireddiffers

    3 credits

    Most dental schools ask for 3 credits and list it as recommended.

    "Microbiology or Immunology (3 cr hrs)" sits inside the 13 named hours of the biological sciences bucket, so it is required here rather than merely recommended. Immunology answers the line just as well. No laboratory is specified for this course.

  • Social sciences and humanitiesrequiredextra here

    2 semesters · 6 credits

    Two separate three hour blocks. "Social sciences - Complete a minimum of 3 semester credit hours and must include one of these: Psychology, Communication Studies." "Humanities - Complete a minimum of 3 semester credit hours and must include one of these: History, Literature, Philosophy, Foreign Language, English Composition." Community college credit is accepted for both blocks, unlike the sciences.

Experience hours

  • Dentist shadowingrequired

    100+ hours

    "100 total hours of shadowing is required and must be completed by the October 1st application deadline." Breadth is prescribed, not just the total: "Shadowing is to be completed within General Dentistry and at least two (2) different dentistry specialty practices, for example, oral surgery, periodontics, orthodontics, etc. Shadowing in public health clinics and other health environments are acceptable. Shadowing can be completed in-person or virtual."

  • Non-clinical volunteeringrecommended

    100+ hours

    Few schools publish a number; committees still read for a service habit held over time.

Letters

  • Committee letterrecommended

    1 letter

    "Committee letters are accepted and counted as one letter, instead of three." A committee letter therefore covers only one of the two required letters here, so plan a second writer alongside it.

  • Science faculty letterrequireddiffers

    1 letter

    Most dental schools ask for 2 letters.

    "You must submit two letters of academic recommendation as part of your application... One of the letters must be from science faculty member or research faculty member, under whom you studied in a university setting." One science letter, not the baseline's two, and a research faculty member counts. Letters must be on official letterhead with the evaluator's mailing address, phone number, email address and signature, and IUSD calls recommenders at random to verify.

  • Faculty letter (any discipline)recommendedextra here

    1 letter

    Two letters are required in total. The first must be science or research faculty; of the second IUSD says, "The second letter may be from an academic area of study or a dentist with whom you have shadowed within the 12 months prior to the date of your application." A professor in any discipline answers that second slot, and so does a dentist, so neither writer is required on its own.

  • Dentist letterrecommendeddiffers

    1 letter

    Most dental schools ask for 1 letter and list it as required.

    Not required. A dentist is one of two accepted writers for the second letter: "The second letter may be from an academic area of study or a dentist with whom you have shadowed within the 12 months prior to the date of your application, and who is able to evaluate your skill, character, and potential for success in the program." Note the 12 month recency window if you choose this route.

Also on the school’s page

IUSD publishes a prerequisites chart built on credit-hour buckets rather than named course sequences: a minimum of 20 semester credit hours of biological sciences, 13 of which must be anatomy or histology with labs (4), physiology (3), microbiology or immunology (3), and cell biology, biochemistry, or molecular biology (3); a minimum of 12 hours of chemistry, being general or inorganic chemistry I and II with labs (8) plus organic chemistry with lab (4); a minimum of 8 hours of general physics I and II with labs; 3 hours of social sciences; and 3 hours of humanities. Only one semester of organic is named, which is unusually light. Applying takes a minimum of 90 semester credit hours, at least 30 of them at a four year college or university, and the bachelor's degree is required at matriculation. "Online courses are not acceptable for science prerequisites," nor are "Advanced Placement (AP) and Dual Credit courses," though "Community college courses for social sciences and humanities are accepted." Required science courses "should be upper level (preferably 200-300 level) and they must be intended for science majors at a 4 year college or university." Prerequisites listed as planned must be finished by May 31 of the entering year. Applicants also complete an IU Grad CAS supplemental application and a Kira video assessment; the AADSAS deadline is 4:00 p.m. EST on October 1. On scores, no minimum is published, and the Class of 2030 averaged a DAT academic average of 440, total science of 440, reading comprehension of 445 to 450, a science GPA of 3.68 and an overall GPA of 3.74; the DAT figures are on the current 200 to 600 scale. DAT scores may not be older than three years and only the most recent attempt is used. Cross-checked against the IU dentistry bulletin's pre-dental requirements page, https://bulletin.iu.edu/iu/dentistry/2025-2026/dds/admission/predental-req.shtml, which lists the same course buckets.
