A TRIBUTE TO DR. BENJAMIN DIENSTEIN

Dr. Benjamin Dienstein, longtime resident of Marin County, a distinguished dentist, clinical professor, teacher, lecturer, and author of many dental journal articles, has died at the age of 105. He is survived by his wife Julie, son Larry, daughter Dianne, and numerous relatives.
Ben, one of six children, was born to immigrant parents in 1915. He attended Stanford University, University of California Berkeley, and University of California San Francisco, where he earned his BA, BS, MS and DDS degrees. He was one of the pioneers of periodontal dentistry at UCSF. He helped establish its Periodontology Department and taught part-time at the UCSF Dental School for over 65 years until he was 102 years old. Throughout the years, he held various titles: Research Assistant, Lecturer, Instructor, Assistant Professor, and Clinical Instructor, and was a member of numerous committees. His private dental practice in Northern California lasted for more than 50 years.
Dr. Dienstein was a founding member and past president of the Northern California Society of Periodontology. He helped to establish the dental insurance, now known as Delta Dental. Dr. Ben associated himself with the American Association for the Advancement of Science, California Academy of Periodontology, Weinmann Periodontal Study Club, New York Academy of Sciences, and Royal Society of Health (Europe), among others. He has been honored with membership in the Mexican Periodontal Society and received the UCSF Alumni Association's highest honor, the Dental Medal of Honor.
To honor Dr. Ben and his contributions to generations of periodontology students at UCSF, a fund has been established in his honor to support research activities for UCSF students that Ben has championed for more than half a century. Remembrances would be gratefully appreciated if sent to the Dienstein Research Fund (B1501), University of California, San Francisco, P.O. Box 45339, San Francisco California 94145-0339.

Still bless Dr Dienstein when I brush any teeth in the healthy way he recommended. He was a gem!

Continue to remember your kind, caring ways, dear Dr Dienstein. You would be proud of my level of oral health at 88, given the effective little brushing hints you gave me as a permanent gift so long ago. Bless you loving soul. The purple lady---Barbara Meislin

Ben was my teacher, colleague, mentor and friend. He was a little, short, man with a big heart and soul. He was smart, funny and dedicated to his profession. When I was in graduate school he taught us inflammation and the four of us graduatestudents argued with him constantly, but he was always patient and helpful (and right). He was definitely old school and could do more with curettes than most of us could do surgically. His patients adored him and so did his students. He was a proud member (as am I) of the DOPES- the Dirty Old Periodontists Extraordinary Society, and theseven or eight of us would meet quarterly for dinner just to stay in touch and shmooze about the old days. Near the end, Ben was almost deaf. I often sat next to him at dinner so I could talk with him up close. On his 99th birthday we presented him with a medal with a 99 engraved on it and he wore it to every dinner. Our group visited him last year in his retirement home; he could barely see or hear but his mind remained intact and he was cheerful and so appreciative of our visit. After the pandemic shut down in March, I called him and we had a nice conversation; his voice still strong. I will miss him as will everyone who had the good fortune to know him during his long and fruitful life.
