Radiographic Bone Loss and Its Relation to Patient-Specific Risk Factors, LDL Cholesterol, and Vitamin D: A Cross-Sectional Study

The influence of patient-specific factors such as medical conditions, low-density lipoprotein cholesterol (LDL-C) or levels of 25-hydroxyvitamin D (25OHD) on periodontal diseases is frequently discussed in the literature. Therefore, the aim of this retrospective cross-sectional study was to evaluate potential associations between radiographic bone loss (RBL) and patient-specific risk factors, particularly LDL-C and 25OHD levels. Patients from a dental practice, who received full-mouth cone beam CTs (CBCTs) and blood-sampling in the course of implant treatment planning, were included in this study. RBL was determined at six sites per tooth from CBCT data. LDL-C and 25OHD levels were measured from venous blood samples. Other patient-specific risk factors were assessed based on anamnesis and dental charts. Statistical analysis was performed applying non-parametric procedures (Mann–Whitney U tests, error rates method). Data from 163 patients could be included in the analysis. RBL was significantly higher in male patients, older age groups, smokers, patients with high DMFT (decayed/missing/filled teeth) score, lower number of teeth, and high LDL-C levels (≥160 mg/dL). Furthermore, patients with high 25OHD levels (≥40 ng/mL) exhibited significantly less RBL. In summary, RBL was found to be associated with known patient-specific markers, particularly with age and high LDL-C levels.

Vitamin D and Its Role in Oral Diseases Development. Scoping Review

Vitamin D is a fat-soluble secosteroid that plays a significant role in the whole body, including the maxillofacial region. The discovery of its receptors in many cells and organs made it possible to reveal the participation of vitamin D not only in the regulation of calcium phosphate metabolism, but also in immune processes, in providing anti-inflammatory and antimicrobial effects, slowing down cell proliferation and stimulating differentiation. In this literature review, we demonstrate the association between low vitamin D levels and the development of recurrent aphthous stomatitis, the course and response to treatment of squamous cell carcinoma of the oral cavity, the severity of periodontal diseases, and the processes of osseointegration and bone remodeling during dental implantation and guided tissue regeneration. The aim of our article was to demonstate a possible connection between vitamin D level and the oral diseases that can be presented at an oral surgery appointment, which will help clinicians to reduce the risk of early dental implant failure, ensure favorable outcomes of augmentative operations, as well as decrease the destructive effects of severe periodontitis and other conditions throug knowledge and timely lab tests and endocrinologist prescriptions.

Surgical treatment with dental implants in a patient with secondary loss of teeth and osteoporosis caused by an imbalance of vitamin D

In recent years, the success of long-term dental implants has remained problematic, especially because of the increasing rate of mineral balance changes in patients with partial loss of teeth, regardless of their age, race and sex. This article describes the experience of 6 years of treatment with dental implants in a patient with secondary loss of tooth and mineral imbalance (osteopenia) due to vitamin D deficiency, in collaboration with endocrinologist. Along with basic dental care, special medicine was prescribed for this pathology. The bone system was monitored through regular blood tests, skeletal bone densitometry and X-ray of the maxillofacial region. This management plan allowed dental implants to be maintained in good condition for 7 years.

Evaluation of FGF-23 and 25(OH)D3 levels in peri-implant sulcus fluid in peri-implant health and diseases

BACKGROUND

There are limited studies to date investigating vitamin D and fibroblast growth factor (FGF)-23 in different peri-implant conditions.

PURPOSE

To evaluate the peri-implant sulcus fluid (PISF) FGF-23 and 25-hydroxy-vitamin D₃ (25(OH)D₃ ) levels in peri-implant health and diseases.

MATERIALS AND METHODS

A total of 90 dental implant sites (peri-implant healthy group [n = 30], peri-implant mucositis group [n = 30], and peri-implantitis group [n = 30]) in 53 participants were included in the study. Probing depth (PD), clinical attachment level (CAL), suppuration (S), modified plaque index (mPI), gingival index (GI), modified sulcus bleeding index (mSBI), and keratinized mucosa width (KMW) were recorded as clinical parameters, and PISF samples were obtained. FGF-23 and 25(OH)D₃ levels were analyzed by enzyme-linked immunosorbent assay.

RESULTS

There were no statistically significant differences in FGF-23 concentrations among the groups (P > .05). The 25(OH)D₃ concentration was significantly lower in peri-implantitis group compared with the other two groups (P < .05). The mean total amount of FGF-23 in the peri-implantitis group was significantly higher than the peri-implant healthy group whereas 25(OH)D₃ total amount was significantly lower in the peri-implantitis group than the peri-implant healthy group. The 25(OH)D₃ concentration was significantly negatively correlated with CAL, PD, mPI, S, GI, and mSBI and statistically significant relationship was found between FGF-23 total amount and these clinical parameters (P < .05). There was a negligible positive correlation between 25(OH)D₃ and FGF-23 concentrations (τ = 0.169; P = .018).

CONCLUSION

Within the limitations of this study, it can be concluded that FGF-23 and vitamin D seems to affect peri-implant bone health, and further studies are needed to explain the association between FGF-23 and 25(OH)D₃ in peri-implant conditions.
