Effects of Vitamin D Supplementation During a Non-surgical Treatment of Generalized Chronic Periodontitis

NCT ID: NCT03162406

Last Updated: 2017-05-23

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: NA
• Total Enrollment: 30 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-05-18
• Study Completion Date: 2018-06-30

Brief Summary

The subjects participating in the trial will be randomly allocated to either the group receiving the treatment under investigation (scaling and root planning (SRP) accompanied by administration of vitamin D) or to a group receiving standard treatment (SRP in conjunction with placebo) as the control. Random assignment of intervention will be done after subjects have been assessed for eligibility and recruited, but before the intervention to be studied begins. After randomization, the two groups of subjects will be followed in exactly the same way and the only differences between them will be the vitamin D/placebo that they will receive.

Detailed Description

It is likely that a chronically low intake of vitamin D and calcium may lead to a negative calcium balance, thus causing a secondary increase in calcium removal from bone, including the alveolar bone. Such bone loss may contribute to weakening of the tooth-attachment apparatus. In addition to its action on skeletal homeostasis, vitamin D, and, in particular, its hormonally active form, 1a,25-dihydroxyvitamin D, has anti-inflammatory and antimicrobial effects via modulation of inflammatory cytokine production by immune cells and stimulated secretion of peptides with antibacterial action by cells of the monocyte-macrophage lineage.These multiple actions of vitamin D are potentially appealing for the management of patients with periodontal disease, whose pathogenesis is based on chronic bacterial-driven inflammation.

Excess of vitamin D leads to a disturbance of the calcium in the body cycle. The symptoms experienced are: weakness, fatigue, headache, nausea, vomiting, diarrhea, polyuria, calciuria, dry mouth, nighttime urination, proteinuria, increased thirst, loss ofappetite, dizziness.

In case of high blood calcium level for a prolonged period, calcium deposits (tissue calcinosis) may occur in the soft tissues, including the kidneys where they cause calculations and calcium deposits in the nephrons, blood vessels, heart, lung and skin. These effects are reversible if the intoxication is detected in time.

Eligibility Criteria

Inclusion Criteria

• All subjects who are in good general health and were diagnosed with GChP (generalized chronic periodontitis) based on the current classification of the AmericanAcademy of Periodontology will be included:
• ≥ 30 years of age,
• at least 15 teeth (excluding third molars and teeth with advanced decay indicated for extraction),
• a minimum of 6 teeth with at least one site each with periodontal probing depth (PPD) and clinical attachment level (CAL) ≥ 5 mm,
• at least 30% of the sites with PPD and CAL ≥ 4 mm and bleeding on probing (BOP);
• Caucasians (defined as European and North African);
• subjects who present a 25(OH)D concentration < 30 ng/mL.

Exclusion Criteria

• pregnancy
• breastfeeding
• current smoking and former smoking within the past 5 years-smoking status will be recorded as smoker (current) or non-smoker (never or former);
• systemic diseases that could affect the progression of periodontitis (e.g. diabetes, immunological disorders, osteoporosis);
• SRP in the previous 12 months;
• antibiotic therapy in the previous 6 months;
• long-term intake of anti-inflammatory medications;
• need for antibiotic pre-medication for routine dental therapy;
• any current ongoing immunological, neoplasia, endocrine, haematological, hepatic, renal, gastrointestinal, neurological, or psychiatric abnormalities or medical disease;
• subjects who used a UV light solarium or any type of vitamin D supplement within two months before the screening visit or planned to travel outside European countries during the study
• subjets under treatment with drugs that may interfere with vitamin D metabolism (e.g., phenobarbital, phenytoin, and glucocorticoids) and those with past or current history of granulomatosis, especially sarcoidosis, urinary lithiasis, and osteomalacia;
• subjects who present a 25(OH)D concentration > 30 ng/mL, serum creatinine >150 mmol/L and and albumin corrected serum calcium >2.65 mmol/L (corresponding to 10.6 mg/dL) at screening,
