The goal of this clinical trial is to evaluate impact of Minimally Invasive Non-Surgical Therapy (MINST) with and without splinting on clinical periodontal parameters and Oral Health Related Quality of Life (OHRQoL) in periodontitis patients with mobile anterior teeth. The main questions it aims to answer are:

• Does splinting provide additional benefit to MINST alone for improving the clinical periodontal parameters ?
• Does splinting provide additional benefit to MINST alone for improving OHRQoL ?

The increased mobility of a periodontally affected tooth can be caused by a shift of centre of rotation of the tooth apically due to clinical attachment loss (CAL) and alveolar bone loss (ABL) and/or due to secondary occlusal trauma.

Tooth splinting continues to be a topic of controversy. It remains one of the most poorly understood and controversial areas of dental therapy.

Minimally invasive non-surgical periodontal therapy (MINST) has been introduced for minimizing tissue trauma and enhancing clinical outcomes by the adjunctive use of magnification devices .

This study aims to compare clinical periodontal parameters and Oral Health Related Quality of Life (OHRQoL) following Minimally Invasive Non-Surgical Therapy (MINST), both with and without splinting, in patients with Stage III and Stage IV periodontitis who have mobile anterior teeth.

Patients will be screened and enrolled based on specific eligibility criteria. Baseline measurements of outcome parameters will be taken, followed by supragingival scaling, and patients will be recalled after one week.

During the subsequent visit, patients will be randomized into either the test group or the control group. The test group will receive MINST along with splinting of the mobile anterior teeth, while the control group will receive MINST alone.

Patients will be recalled after 8 weeks and 6 months to assess changes in the outcome measurements.

Inclusion Criteria:

• Inclusion criteria at the patient level: systemically healthy patient with presence of stage III or IV periodontitis, age ≥ 18 years.
