Conditions
Summary
This randomized clinical trial aims to compare the clinical and radiographic outcomes of the Vector®️ ultrasonic system and mini-five curettes in non-surgical periodontal therapy. Patients diagnosed with periodontitis will be randomly assigned to either ultrasonic instrumentation or manual instrumentation. Clinical periodontal parameters and radiographic bone level changes will be evaluated at baseline, 1, 3, 6, and 12 months. The primary objective is to assess differences in clinical attachment level and probing depth reduction between the two treatment modalities.
Eligibility
Inclusion Criteria1
- Adults aged 18-65 years Willing to participate and provided written informed consent Presence of single-rooted teeth in both maxilla and mandible with vertical bone defects (radiographic intrabony defect ≥2 mm and probing depth ≥5 mm) Diagnosis of Stage III or Stage IV periodontitis Systemically healthy or Systemically healthy patients or American Society of Anesthesiologists (ASA) physical status I-II.
Exclusion Criteria1
- Periodontal treatment within the last 6 months Teeth with furcation involvement Smoking more than 10 cigarettes per day Pregnancy Age under 18 years Patients unwilling to attend regular follow-up visits Previously endodontically treated tooth at the treatment site Poor compliance with oral hygiene instructions Single-rooted teeth with horizontal bone loss extending close to the apical third Teeth with mobility grade II or III Previous flap surgery or regenerative periodontal treatment at the study site
