Dr. Hidetada Moroi, DMD
Boston Periodontist & Dental Implant Specialist
Dr. Hidetada Moroi, DMD, is a board-certified periodontist and dental implant specialist with advanced training in periodontics, dental implant surgery, reconstructive dental surgery, and periodontal plastic surgery. Originally from Japan and a third-generation dentist, Dr. Moroi has dedicated his career to helping patients preserve their natural teeth, restore oral function, and achieve healthy, natural-looking smiles.
He has practiced in Massachusetts since 1999 and has developed extensive experience treating complex periodontal and implant cases. His approach combines advanced surgical training with a strong emphasis on achieving both functional and esthetic results.
In addition to his private clinical practice, Dr. Moroi is an educator and researcher. He has been involved with the Tufts University School of Dental Medicine for decades and currently serves as an Assistant Clinical Professor. He has also authored and co-authored peer-reviewed publications addressing periodontal regeneration, implant dentistry, bone regeneration, soft-tissue management, and esthetic rehabilitation.
A Third-Generation Dentist From Japan
Dentistry is part of Dr. Moroi’s family history. A third-generation dentist, he grew up in Japan with an early appreciation for the profession and the difference that thoughtful dental care can make in a person’s health and quality of life.
Dr. Moroi earned his dental degree from Osaka Dental College in Osaka, Japan, in 1990. Following dental school, he came to Boston to pursue advanced postgraduate education in periodontics and implant dentistry at Tufts University School of Dental Medicine.
His advanced training in the United States provided the foundation for a career focused on treating periodontal disease, preserving natural teeth, replacing missing teeth with dental implants, and managing the hard- and soft-tissue challenges that can accompany complex dental reconstruction.
After completing his postgraduate training, Dr. Moroi established his professional career in Massachusetts, where he has practiced since the late 1990s.
Advanced Training in Periodontics and Dental Implants
Periodontics focuses on the health of the gums and supporting structures surrounding the teeth. Healthy periodontal tissues are essential not only for preserving natural teeth but also for creating a stable foundation for dental implants and other restorative treatments.
Dr. Moroi has advanced training in a broad range of periodontal and implant procedures, including:
- Periodontal Disease Treatment
- Dental Implant surgery
- Reconstructive Dental Surgery
- Bone Regeneration and Augmentation
- Periodontal Plastic Surgery
- Soft-Tissue Grafting
- Gingival and Esthetic Procedures
- Implant-Site Development
- Complex Periodontal and Implant Rehabilitation
His clinical philosophy emphasizes the relationship between health, function, stability, and aesthetics.
For patients undergoing complex dental reconstruction, the condition of the gums and underlying bone can be just as important as the teeth themselves. Dr. Moroi’s periodontal and implant expertise allows him to address these supporting structures as part of a comprehensive treatment plan.
A Focus on Preserving Teeth and Restoring Function
One of Dr. Moroi’s central goals is helping patients maintain their natural teeth whenever possible.
Periodontal disease can damage the tissues and bone that support teeth, potentially leading to tooth mobility and tooth loss if left untreated. Through periodontal therapy and appropriate surgical treatment, Dr. Moroi works to control disease and create healthier conditions around the teeth.
When a tooth cannot be saved, dental implants can provide another option for restoring function and appearance.
Dr. Moroi’s training in both periodontics and implant dentistry allows him to evaluate the gums, bone, teeth, and implant site as an interconnected system. This perspective can be especially important when treating patients who have experienced bone loss, gum recession, or other complications associated with missing teeth.
Advanced Dental Implant and Reconstructive Surgery
Successful implant treatment involves much more than placing an implant.
In many cases, the available bone and soft tissue must be carefully evaluated and, when necessary, reconstructed to create an appropriate foundation for implant placement and restoration.
Dr. Moroi has advanced training in implant surgery, bone regeneration, reconstructive dental surgery, and periodontal plastic surgery, giving him experience with the surgical aspects of complex implant treatment.
His academic and clinical interests have included techniques for improving both the functional and esthetic aspects of implant therapy, including bone and soft-tissue management.
His published work includes research and case reports involving bone regeneration, implant-site development, periodontal plastic surgery, and esthetic rehabilitation.
Research in Periodontics and Implant Dentistry
Dr. Moroi’s involvement in dentistry extends beyond clinical practice.
He has published and co-authored numerous articles in professional and peer-reviewed dental journals. His research interests have included periodontal regeneration, implant dentistry, bone grafting and regeneration, soft-tissue management, and esthetic implant treatment.
Among his recent publications is a 2024 article in the International Journal of Periodontics & Restorative Dentistry examining the use of synthetic carbonate apatite as a bone substitute in implant treatments. The article reported on clinical cases involving immediate implant placement and guided bone regeneration.
His earlier publications have addressed topics including gingival grafting, esthetic rehabilitation, implant-site development, bone regeneration, and complex implant therapy.
This continued involvement in research reflects Dr. Moroi’s commitment to staying engaged with developments in modern periodontics and implant dentistry.
Educator and Assistant Clinical Professor at Tufts
Dr. Moroi is also committed to educating the next generation of dental professionals.
He has taught in the Department of Periodontology at Tufts University School of Dental Medicine since 1996 and currently holds a faculty position as an Assistant Clinical Professor. Tufts’ current faculty directory lists Dr. Moroi among its School of Dental Medicine faculty.
His academic involvement gives him the opportunity to share his clinical experience and knowledge of periodontal and implant treatment with dental students and other professionals.
Dr. Moroi has also participated in continuing education and professional seminars in both the United States and Japan, sharing his knowledge in the areas of periodontics and implant dentistry.
Board-Certified in Periodontology
Dr. Moroi is a Diplomate of the American Board of Periodontology, reflecting his advanced training and professional commitment to the specialty of periodontics.
He is also a member of several leading professional organizations, including:
- American Dental Association
- Massachusetts Dental Society
- American Academy of Periodontology
- Academy of Osseointegration
His professional affiliations connect him with organizations dedicated to advancing periodontal health, dental implantology, continuing education, and evidence-based dental care.
A Boston Periodontist With an International Perspective
Dr. Moroi’s background gives him a uniquely international perspective on dentistry.
Originally from Japan, he completed his initial dental education there before coming to Boston for advanced specialty training. He has maintained professional connections with both the United States and Japan and has participated in continuing education and professional presentations in both countries.
Today, he brings that international experience together with decades of clinical practice in Massachusetts.
His background is particularly meaningful in Boston, an international and culturally diverse city where patients come from many different backgrounds and communities.
Focused on Function, Health, and Esthetics
Dr. Moroi believes that periodontal and implant treatment should address more than one dimension of a patient’s oral health.
A successful treatment plan should consider health, function, stability, and appearance together.
This is particularly important in reconstructive and implant dentistry, where the gums, bone, teeth, and facial aesthetics all contribute to the final result.
His advanced training in periodontal plastic surgery and implant reconstruction allows him to pay close attention to the soft tissues and supporting structures that can influence the appearance of the finished smile.
The goal is to help patients achieve results that look natural while providing the stability and function necessary for long-term oral health.
Life Outside of Dentistry
Outside the office and university, Dr. Moroi enjoys staying active and spending time pursuing his personal interests.
He enjoys running, playing golf, and cooking.
Cooking is a particular passion, and one of his long-term dreams is to open a restaurant of his own. His interest in food and cooking provides a creative outlet away from dentistry and reflects the same attention to detail and appreciation for craftsmanship that he brings to his professional life.
