Peri-implantitis Diagnosis and Prognosis Using Biomarkers: A Systematic Literature Review.

PURPOSE: To summarize the latest scientific literature regarding the concentrations of biomarkers in saliva and peri-implant crevicular fluid (PICF) of healthy implant (HI) patients and patients with peri-implant mucositis (PIM) and peri-implantitis (PI). MATERIALS AND METHODS: The literature review was performed according to PRISMA guidelines. The databases used were PubMed MEDLINE, ScienceDirect, and Cochrane Library. A combination of keywords was used, and selection criteria were applied. Selected articles were published between February 1, 2017, and February 1, 2022, written in English, conducted in humans, and examined the levels of saliva and PICF biomarkers in PI patients and compared them to HI/PIM patients. RESULTS: A total of 16 publications were selected, involving a total of 1,117 patients with 1,346 implants. Qualitative analysis revealed 49 different biomarkers, the levels of which were compared between groups. After evaluating the most frequently studied biomarkers, significantly higher values of IL-1ß, RANKL, sRANKL, IL-6, TNF-α, TNFSF12, MMP2, and MMP8 levels were observed in the PI group than in the HI group. CONCLUSIONS: Of all 49 biomarkers evaluated, IL-1ß and RANKL have potentially the highest diagnostic significance in the assessment of peri-implant inflammatory conditions, as differences were observed between all three groups (HI < PIM < PI), but data from current publications were not fully sufficient to provide strong evidence.

The Use of Autogenous Teeth Tissues Grafts for Alveolar Bone Reconstruction: a Systematic Review.

Objectives: Enough bone around the implant is an important factor in ensuring the stability and longevity of the implant. Therefore, alveolar bone regeneration procedures are often required. A relatively new bone substitute is made from autogenous teeth. There are more and more studies in the scientific literature that perform regenerative alveolar bone procedures using autogenous tissues substitutes made from extracted teeth. The objective of this systematic literature review is to systematize information and present conclusions about the effectiveness of this regenerative material. Material and Methods: Scientific articles were selected using the PRISMA recommendations. Publications have been carried out since January 1, 2012 to January 1, 2022. The review includes articles in English, clinical studies in humans who underwent bone augmentation prior to or during dental implantation using an autogenous teeth tissues substitute. Results: A total of 7 publications were included in this systematic literature review. Summarizing the data of the publications, 258 patients participated in the studies, 240 subjects were included in the results for various reasons, and a total of 298 implants were inserted. No statistically significant results were found in the five studies. Two studies comparing autogenous tooth graft with xenogeneic bone graft and autogenous teeth tissues showed statistically significant positive results in autogenous tooth group. Conclusions: Within the limitations of this study, autogenous tissues graft derived from teeth are an effective material and can be used as an alternative to other bone grafts existing on the market. Further studies with a longer follow-up period are needed to validate these findings.

The Efficiency of Different Arthroscopic Discopexy Techniques Based on Clinical and Radiographic Findings: A Systematic Review.

The aim of this systematic review was to evaluate the effectiveness of different temporomandibular joint arthroscopic discopexy techniques. The systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement and an electronic search was performed using MEDLINE (PubMed), The Cochrane Library, ScienceDirect databases using a combination of the terms ''discopexy,'' ''disc recapture,'' ''disc fixation,'' and ''temporomandibular joint'' to identify clinical trials published from 2010. In total, 493 records were screened, of which only 9 fulfilled the inclusion criteria and were included in qualitative data synthesis. The results of clinical findings evaluation showed that arthroscopic discopexy statistically significantly improved levels of pain (VAS) and maximum interincisal opening whereas magnetic resonance imaging evaluation showed disc position improvement of up to 90% to 100%. In conclusion, this review provides the evidence of the potential benefits of arthroscopic disc fixation in the treatment of patients with internal derangements : reduced pain, increased maximum interincisal opening, and improved disc position evaluated by magnetic resonance imaging, whereas disc fixation using suturing techniques seems to be the most appropriate method.

Management of bisphosphonate-related osteonecrosis of the jaw using teriparatide treatment: A systematic review.

OBJECTIVE: To systematically review the current literature and determine whether the additional TPTD administration for patients with BRONJ is an effective treatment modality. MATERIAL AND METHODS: The systematic review was registered in the PROSPERO (CRD42021242796) and conducted according to the PRISMA statement. An electronic search was performed using MEDLINE (PubMed), ScienceDirect, The Cochrane Library and LILACS databases using a combination of the keywords "Bisphosphonate-Associated Osteonecrosis of the Jaw"[Mesh], "treatment" to identify studies published from 2010. RESULTS: The authors found 8 articles that met the inclusion criteria of this systematic review. According to two studies, TPTD was statistically significantly associated with a greater BRONJ lesion resolution, compared to control group (p<0.05). However, one article showed no significant difference in proportion of resolved lesions (p=0.478). Regarding the effectiveness of TPTD treatment according to administration frequency, daily injection group showed no significant changes in the clinical stage of BRONJ, no difference in the percentage of bone formation on patients osteolysis, compared to weekly injections. Concerning bone resorption/regeneration markers, all the included studies showed that bone resorption markers significantly increased after 3-month TPTD administration. In a study which used multivariate analysis between TPTD and non-TPTD groups using age, BMI, duration of BP usage, the difference in s-OC values after 3 months of the treatment was significant (p<0.05). CONCLUSION: This review provides evidence for the potential benefits of additional TPTD administration for patients with BRONJ being an effective treatment modality.
