Brief summary

This study will evaluate, in an adult population (n=448) previously diagnosed with gingivitis and/ or periodontitis, the tooth loss rate and its potential associated factors such as diabetes, smoking, bruxism, cardiovascular diseases, and also the effect of supportive periodontal therapy on these factors, with an up to 50 years of follow-up period. Significant results of the present study will help in the future reduction of tooth loss among periodontally involved patients.
