      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Assigning patients to three groups receiving vitamin D and SRP, vitamin D and calcium, and SRP and SRP alone.It will be done by blocking method and using 6 blocks.
Patients are divided into three groups using a randomized balanced block method with a block size of 6. A random sequence is created by an epidemiologist by running an online application on the website (https://www.sealedenvelope.com).</study_design>
      <phase>2-3</phase>
      <hc_freetext>Condition 1: Periodontitis. Condition 2: Vitamin D deficiency.</hc_freetext>
      <i_freetext>Intervention 1: The first Intervention group: Scaling &amp; Root Planning of the whole mouth and then hygiene training is done similarly by flossing and brushing with the modified Bass method. After two weeks of SRP, Prescribe 50,000 IU of vitamin D weekly and 1,000 mg of calcium supplement daily. Intervention 2: The second intervention group: Scaling &amp; Root Planning of the whole mouth and then hygiene training is done similarly by flossing and brushing with the modified Bass method. After two weeks of SRP, Prescribe 50,000 IU of vitamin D weekly. Intervention 3: Control group: Scaling &amp; Root Planning of the whole mouth and then hygiene training is done similarly by flossing and brushing with the modified Bass method. No medication is prescribed for this group as a control group.</i_freetext>
