Coursework

  • Biology with labrequired

    2 semesters · 8 credits · lab

    Two semesters with lab. As universal for dental school as it is for medical.

  • 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 labrequired

    2 semesters · 8 credits · lab

    Two semesters with lab at most schools. A small number accept one semester plus biochemistry; confirm on the school's page before planning around it.

  • Biochemistryrequired

    1 semester · 3 credits

    Roughly half of schools require a semester and the share grows every cycle. The DAT does not test it, but first-year dental biochemistry assumes you have seen it.

  • Physics with labrequireddiffers

    6 credits · lab

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

    Six semester or nine quarter hours, not the baseline's eight. Worth knowing how the table is written: biology, general chemistry and organic chemistry each read "(with labs)" and the physics row reads simply "Physics", but the page nowhere says the physics laboratory is waived, so this line keeps it. Ask admissions before planning to skip it.

  • English or writing-intensiverequired

    2 semesters · 6 credits

    "For the English requirement, 6 semester hours are accepted or the completion of a Bachelor of Arts or a Bachelor of Science degree." A completed bachelor's degree satisfies the line on its own.

  • Advanced biologyrecommendedextra here

    1 semester · 3 credits

    SIU prints a second table headed "We strongly suggest selecting several additional higher-level courses", one semester each: Anatomy, Physiology, Microbiology, Cell and Molecular Biology, Histology, Immunology, Genetics, and Neural Science or Neural Physiology. None is required, but "preference will be given to applicants demonstrating exemplary academic performance in additional higher-level science courses while taking full academic loads."

  • Anatomy and physiologyrecommended

    3 credits

    Named by a minority of schools and useful preparation for the first year regardless.

  • Microbiologyrecommended

    3 credits

    Required at a meaningful minority and recommended widely; a strong pick for the spare science slot.

Experience hours

  • Dentist shadowingrecommendeddiffers

    100+ hours

    Most dental schools ask for 100+ hours and list it as required.

    "SIU School of Dental Medicine does not require extracurricular activities and dental shadowing experience but highly recommends these experiences." No hours figure is published. The page names "Observing a General Dentist" and "Observing a Dental Specialist" as the examples, and warns that "Applicants that are shadowing or observing will complete this without compensation or volunteer hours", and that the school "is unable to provide dental volunteer/shadowing opportunities."

  • 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

    "If the applicant's undergraduate institution has a pre-health profession committee, a letter or letter packet by committee members can be submitted in place of the three required letters of recommendation. This packet or letter will be submitted to AADSAS as one individual letter." It replaces all three, the two science letters included.

  • Science faculty letterrequired

    2 letters

    Two, as in the baseline, but SIU is unusually specific about who counts: "Letters must be from science professors who have taught and graded the applicant at the university level. Science letters should include the course name, number and professors signature." A research supervisor who never graded you does not qualify. Three letters in total, uploaded to AADSAS by the evaluators.

  • Dentist letternot required here

    No dentist letter is required here. The third letter is a "ONE Letter of Choice, One letter by an evaluator of the applicant's choice. This evaluator could be another professor, a mentor or dentist." A dentist is one option among several, not the ask.

Also on the school’s page

SIU publishes a required-subjects table in semester hours: biology with labs 8, general chemistry with labs 8, organic chemistry with labs 8, physics 6, biochemistry 3, English 6. "Applicants are required to complete the following coursework with a C or better by July of the intended entering year. Grades of D or lower will not be accepted. The SIU School of Dental Medicine will accept pass/fail grades for Spring 2020 coursework only. We do not accept AP credit for the following subjects." The floor is "three academic years, 90 semester or 135 quarter hours, of undergraduate course work", with "A maximum of 60 semester hours from an accredited community or junior college" allowed, and "Science courses should not be survey courses or other such courses designed for non-science majors." On scores there are no published numbers to record: the school's own FAQ says "Because the Dental School has competitive admission, there are no fixed minimum GPA and DAT scores", though "All applicants must take the Dental Admissions Test (DAT); no exceptions are made." Scores "must be received before the application deadline of November 15th", the DAT "should be taken before September 15th" to make the first round of interviews, and it "is valid for three years before matriculation." Two pages disagree slightly on where prerequisites may be taken: the requirements page says "at an accredited college or university in the United States", the FAQ says the United States or Canada; this file follows the stricter requirements page. Residency matters here: "As a state institution, established to provide dentists for the State of Illinois and supported by the taxpayers of Illinois, the School gives priority to admission of Illinois residents." Volunteering is listed among the extracurricular examples but carries no published number.
