Remarkable Improvement of Periodontal Diseases (PD)and Diabetic State with Weight Reduction by Super Low Carbohydrate Diet (LCD)

The case was 57-year-old male with the past history of post-operation of Tetralogy of Fallot (TOF) at 11 years old. For dental problems, he visited a dentist and was diagnosed as periodontal diseases (PD) and Type 2 diabetes mellitus (T2DM) with 7.8% of HbA1c. His teeth showed moderate to severe PD and chronic periapical periodontitis due to carious teeth. He was treated for PD and T2DM in dental and internal medicine departments of the hospital. As our formula meal, super low carbohydrate diet (LCD) with 12% of carbohydrate ratio was started. Then, his weight decreased from 100kg to 90 kg in 3 months and HbA1c decreased from 7.8% to 5.4% in 4 months with normalized C-reactive protein (CRP) value. His clinical progress was satisfactory with effective results of dental treatment and LCD. Recent consensus guidelines by International Diabetes Federation (IDF) and European Federation of Periodontology (EFP) recommend the both treatments of PD and diabetes by dentist and internist together. Authors have continued clinical practice and research for years concerning LCD through Japan LCD promotion association (JLCDPA). This case would become some reference from PD and diabetic points of view.
