Dr. Paul Goldhaber, professor of Periodontology and a specialist in gum diseases will become dean of the Harvard School of Dental Medicine July 1, President Pusey announced yesterday.

Goldhaber replaces Dr. Roy O. Greep, who resigned last July to become director of the Medical School's Laboratory of Human Reproduction. Dr. James H. Oaks has served as acting dean this year.

"We plan to take the lead in developing a new, model dental curriculum that will better enable the future dental graduate to meet the demands of society as an integral member of the health team," Goldhaber said yesterday.

Curriculum Changes

Several curriculum changes are planned, Goldhaber said, including a move into hospitals "on a rotating internship, or externship basis" for a good portion of the clinical training period, the addition of electives that can be taken at the Medical School, at Harvard College, or at M.I.T., and a reduction of summer vacations from three months to one month.

"We could do anything we wanted if we had the money," Goldhaber said, "but although we may be the wealthiest private dental school in the country, the yearly income from this source is only a fraction of the appropriation obtained by state schools."

State dental schools average about $2 million per year, Goldhaber said, adding that Harvard's $6 million endowment would have to be raised to about $40 million in order to earn that much interest. The Dental School, Harvard's smallest graduate school with only 16 students admitted each year, celebrates its 100th anniversary in July.
