“…No peri‐implantitis was diagnosed for any of the subcrestal implants. The incidence of peri‐implantitis of 3.63% at implant level and 9.1% at the patient level were lower when compared to the other reported data (Derks et al, ; Derks & Tomasi, ; French, Grandin, & Ofec, ).…”

Objectives This randomized clinical trial analyzed the long‐term (5‐year) crestal bone changes and soft tissue dimensions surrounding implants with an internal tapered connection placed in the anterior mandibular region at different depths (equi‐ and subcrestal). Materials and methods Eleven edentulous patients were randomly divided in a split‐mouth design: 28 equicrestal implants (G1) and 27 subcrestal (1–3 mm) implants (G2). Five implants were placed per patient. All implants were immediately loaded. Standardized intraoral radiographs were used to evaluate crestal bone (CB) changes. Patients were assessed immediately, 4, 8, and 60 months after implant placement. The correlation between vertical mucosal thickness (VMT) and soft tissue recession was analyzed. Sub‐group analysis was also performed to evaluate the correlation between VMT and CB loss. Rank‐based ANOVA was used for comparison between groups (α = .05). Results Fifty‐five implants (G1 = 28 and G2 = 27) were assessed. Implant and prosthetic survival rate were 100%. Subcrestal positioning resulted in less CB loss (−0.80 mm) when compared to equicrestal position (−0.99 mm), although the difference was not statistically significant (p > .05). Significant CB loss was found within the G1 and G2 groups at two different measurement times (T4 and T60) (p < .05). Implant placement depths and VMT had no effect on soft tissue recession (p > .05). Conclusions There was no statistically significant difference in CB changes between subcrestal and equicrestal implant positioning; however, subcrestal position resulted in higher bone levels. Neither mucosal recession nor vertical mucosa thickness was influenced by different implant placement depths.

“…Besides a state of chronic hyperglycemia, other risk factors associated with an increased oral Candida carriage include habitual tobacco smoking, edentulism, denture‐wearing, and poor oral hygiene status . ‒ These risk‐factors have also been shown to increase the risk of peri‐implant diseases . ‒ In the present study, tobacco smokers and individuals with systemic conditions other than chronic hyperglycemia were excluded to minimize the risk of bias in the reported results.…”

Background There are no studies that have investigated the presence of yeasts in the subgingival oral biofilm (OB) of type‐2 diabetic and non‐diabetic patients with peri‐implantitis. The aim was to assess the presence of yeasts in the subgingival OB of patients with type 2 diabetes and peri‐implantitis and patients with peri‐implantitis without diabetes. Methods Patients with type 2 diabetes with peri‐implantitis (group A), non‐diabetic individuals with peri‐implantitis and without diabetes (group B), and individuals with and without peri‐implantitis (group C) were included. Lifestyle‐related and demographic data were collected using a questionnaire and hemoglobin A1c levels were measured. Peri‐implant plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were evaluated and crestal bone loss (CBL) were measured. Subgingival OB samples were collected and oral yeasts species were identified using ChromAgar medium. Level of significance was set at P <0.05. Results The mean age of individuals in groups A (n = 43), B (n = 41), and C (n = 42) were 55.6 ± 6.4, 54.6 ± 4.5, and 57.1 ± 3.3 years, respectively. The mean HbA1c levels were higher in group A (P <0.01) than groups B and C. Peri‐implant PI (P <0.01), BOP (P <0.01), PD (P <0.01), and CBL (P <0.01) were significantly higher in group A compared with patients in groups B and C. Peri‐implant PI (P <0.05), BOP (P <0.05), PD (P <0.05), and CBL (P <0.05) were significantly higher among patients in group B compared with group C. Subgingival yeasts were more often isolated from the OB of patients in groups A (74.4%) and B (46.3%) than group C (7.1%). The most common yeast species identified in all groups was Candida albicans. The CFU/mL for subgingival yeasts were higher in group A than groups B (P <0.01) and C (P <0.01). The CFU/mL for subgingival yeasts were higher in group B than group C (P <0.01). Conclusion Candida species (predominantly C. albicans) were more often present in the subgingival OB of patients with and without type 2 diabetes with peri‐implantitis than systemically healthy individuals without peri‐implant diseases.

In the present study, tobacco‐smokers and individuals with systemic diseases were excluded to minimize the risk of bias in the reported results.…”

Background:There are no studies that have investigated the presence of Candida species in the subgingival oral biofilm (OB) of patients with peri-implantitis.Purpose: The aim was to assess the presence of Candida species in the subgingival OB of patients with peri-implantitis.Materials and Methods: Individuals with (group A) and without (group B) peri-implantitis were included. Life style related and demographic data were collected using a questionnaire. In both groups, peri-implant plaque-index (PI), bleeding-on-probing (BOP), and probing-depth (PD) were evaluated and crestal bone loss (CBL) were measured on digital bitewing radiographs. In both groups, subgingival OB samples were collected using sterile paper points. Identification of Candida species was performed using ChromAgar medium and colony forming units per milliliter (CFU/mL) were determined. Statistical analysis was performed, and level of significance was set at P < 0.05. Results:The mean age of individuals in groups A (n = 43) and B (n = 41) were 52.2 ± 4.4 and 55.1 ± 2.3 years, respectively. All participants were male. In groups A and B, implants were in function for 7.4 ± 1.3 and 6.8 ± 0.6 years, respectively. Scores of peri-implant PI (P < 0.001), BOP (P < 0.001), PD (P < 0.001), and CBL (P < 0.001) were significantly higher in group A than group B. Subgingival Candida was isolated from the OB of 33 (76.7%) patients in group A and 5 (12.2%) individuals in group B. The most common yeast species was Candida albicans, which was isolated from 67.4% to 60% individuals in groups A and B, respectively. The number of subgingival oral yeasts CFU/mL were significantly higher in group A (3147.54 ± 1052.6 CFU/mL) compared with group B (496.68 ± 100.2 CFU/mL; P < 0.01).Conclusion: Candida species (predominantly C. albicans) are present in the subgingival OB of patients with peri-implantitis. Community-based efforts toward routine oral hygiene maintenance are needed to improve oral health and minimize the risks of peri-implant diseases in populations. K E Y W O R D Salveolar bone loss, dental implant, probing depth, yeast Oral Candida species are commensal oral fungi and are often isolated from the oral cavity of healthy patients. 8,9 It has also been reported that the subgingival environment may serve as a haven for various Candida species. 9 In a recent observational cross-sectional study, Matic Petrovic et al. 9 compared the prevalence of Candida species in the subgingival areas with the dorsal surface of tongue. Although the dorsum of the tongue often harbors oral Candida species 8 ; in the study by Matic Petrovic et al. 9 Candida species was present in the subgingival area of nearly 16% individuals and were absent on the tongue.Moreover, besides adherence to teeth and oral mucosal surfaces, yeasts can also adhere to nonbiological surfaces, such as dental materials, for example, titanium implants. 7,10 Results from an experimental study 10 showed Candida albicans biofilm thicker on the body surfaces of the tissue-and bone-level implants compared with other...
