Purpose: Diminished bone levels or the lack of osseointegration can lead to higher rates of failure of dental implants. The present study is aimed to evaluate the correlation between hypertension, diabetes mellitus and hyperlipidemia, on the marginal bone loss (MBL) surrounding dental implants among patients attending the University of Nevada, Las Vegas dental clinics. Methods: Clinical notes from patients at the University of Nevada, Las Vegas (UNLV) dental clinics were analyzed using AxiUm™ software. The study included patients with dental implants diagnosed with hypertension, diabetes mellitus, and hyperlipidemia who attended the UNLV School of Dental Medicine clinics from 2012 to 2022. Exclusions were made for patients with acquired immune deficiency syndrome and those with a limited number of radiographs. A search was conducted using keywords such as ‘systemic disease,’ ‘marginal bone loss,’ ‘dental implant,’ ‘high cholesterol,’ ‘hypertension,’ and ‘diabetes’ within the system. Results: Out of 1,310 potentially eligible patients, 57 fulfilled the inclusion criteria. The total number of evaluated implants was 165. 18% of the sample patients were 55 to 64 years of age, and 79% were 65 or above. 45.6% of patients reported having more than four systemic diseases and 67% of patients had four or more prescription medications. Patients diagnosed with hypertension (78.95%) or hyperlipidemia (73.68%) had the highest presence of marginal bone loss surrounding the dental implant(s) while those with diabetes (40.35%) had the least amount of MBL. Patients diagnosed with both hypertension and hyperlipidemia (29.82%) experienced the highest incidence of MBL around implants. The medications prescribed to combat these health issues, such as statins and antihypertensive, also showed the same trends and corresponded with a higher prevalence of MBL. Conclusions: Within the limitations of the present investigation, patients diagnosed with hyperlipidemia and hypertension were more likely to exhibit MBL surrounding dental implants.

Periodontitis is a commonly occurring inflammatory oral disease affecting a large proportion of global and US adults and is characterized by the destruction of the tooth-supporting apparatus. Its etiology is multifactorial, and type 2 diabetes and diet play critical roles in its remission and progression. However, few studies have addressed nutritional and serum vitamin D status in adults with periodontitis in the presence of diabetes. A cross-sectional study (n = 78), and a sub-set of age- and BMI-matched case–control studies (n = 50), were conducted to examine differences in dietary and cardiometabolic variables, and serum vitamin D in adults with periodontitis with or without diabetes. Participants provided fasting blood samples and 24-h diet recalls on at least two different days. Data on health history, body weight, height, nutritional habits, and clinical features of periodontitis were also collected. The Mann–Whitney U Test (with exact p-value estimation by Monte Carlo simulation) was used to examine differences by diabetes status in continuous and ordinal variables. Results revealed significantly lower serum vitamin D, and dietary intake of fruits, vegetables, dairy, vitamins A and C in adults with periodontitis with vs. without diabetes in the sub-study (all p < 0.05). In the overall sample, adults with diabetes presented with higher caries risk measures and lower numbers of teeth than those without diabetes; plaque and bleeding scores did not differ by diabetes status. Finally, a significant associations of food habits was observed, especially consuming protein-rich foods twice a day with a lower bleeding score, and daily consumption of fried or fast foods with a fewer number of teeth present (all p < 0.05). The present findings show significant dietary and serum vitamin D inadequacies among adults with periodontitis, and diabetes further aggravates the observed malnourishment and oral health.
