Successful Periodontal Management Of Stage Ⅲ Grade C Periodontitis Patient

Stage Ⅲ/IV grade C (Ⅲ/Ⅳ-C) PD in particularly young individuals, characterized by minimal biofilm accumulation, severe bone loss and rapid clinical attachment loss (CAL), often leads to early tooth loss and carries significant risk potential. A 23 year-old female patient presented with the chief complaint of tooth mobility in 2013.Intraoral examination revealed a palatal periodontal defect of maxillary incisors accompanied by a probing depth of 8mm,gradeⅠmobility, bone loss extending to apical 1/3 as well as 50% PD>3.4 mm and BOP 86%.The diagnosis is Stage Ⅲ Grade C periodontitis. Following non-surgical periodontal therapy, including oral hygiene instruction, full-mouth supragingival scaling subgingival scaling and root planning, standard supportive periodontal therapy was performed biannually over a 12-year period. The latest reevaluation revealed well-maintained periodontal health with tooth mobility decrease and bone regeneration. The overall treatment concepts and goals of Ⅲ/Ⅳ-C PD are not markedly different from chronic periodontitis. However, given the young age and extensive bone loss, early and comprehensive treatment along with consistent maintenance is required to halt further periodontal destruction and optimize attachment gain. This case report illustrates that Ⅲ/Ⅳ-C PD can achieve optimal therapeutic outcomes, even bone regeneration, through non-surgical treatment. A successful periodontal management demands collaboration between specialists and patients, encompassing clinical expertise (diagnostic acuity and procedural rigor) and patient adherence. Meanwhile, the successful management, particularly in long-term case, will further reinforce our confidence in periodontal treatment.
