Abstract
The objective of this study was to assess clinical measurements related to the effectiveness of bisphosphonate (BP) administration as a supplement to conventional dental treatment in patients free of bone-related diseases using a network meta-analysis. Only randomized controlled trials (RCTs) were included that provided dental clinical measurements on human patients treated with BPs with or without similar untreated controls or treated with placebo. Information sources included a systematic search of 17 electronic databases up to August 2020, complemented by manual searches. Risk of bias assessment was performed with the revised Cochrane risk of bias tool for randomized trials (RoB 2.0). Extracted measurements were pooled according to time of evaluation. The random-effects model by DerSimonian and Laird was used to calculate mean differences (MDs) and the respective 95% confidence intervals (CIs). Seven RCTs were included in the network meta-analysis, assessing 391 subjects reporting on periodontal treatment effects after 2 to 12 mo of BP administration. BP treatment was associated with significant improvement of most clinical measurements, compared with BP-naive controls. According to the network ranking, alendronate was more efficient in improvement of probing depth and clinical attachment gain when compared to zoledronate or alendronate/risedronate. Similarly, the local application of alendronate as a gel was more effective than the oral administration. A long-term analysis of the pharmaceutical effects was not possible due to insufficient data. The current review, performed according to existing guidelines, included only RCTs and, through appropriate statistical analyses, provided precise estimates for most assessed outcomes. However, no adverse effects or long-term treatment results were analyzed due to inadequate pertinent data. BP administration seems to be beneficial in the short term for the treatment of periodontal diseases, mainly through controlling periodontal inflammation.

Abstract
One of the most important aspects of bone remodeling is the constant turnover mainly driven by the mechanical loading stimulus. The remodeling process produces changes not only in the bone microarchitecture but also in the density distribution of the mineralized matrix - i.e. in calcium concentrations- and in the osteocyte lacunar network. Synchrotron radiation-based X-ray microtomography (microCT) has proven to be an efficient technique, capable to achieve the analysis of 3D bone architecture and of local mineralization at different hierarchical length scales, including the imaging of the lacuno-canalicular network. In the present study, we used microCT within a conceptual study of jawbone remodeling, demonstratively focusing the investigation in two critical contexts, namely in the peri-dental and the peri-implant tissues. The microCT analysis showed that a relevant inhomogeneity was clearly present in both peri-dental and peri-implant biopsies, not only in terms of microarchitecture and mineralization degree, but also considering the lacunar network, i.e. size and numerical density of the osteocyte lacunae. The correlated histological results obtained on the same samples confirmed these observations, also adding information related to non-mineralized tissues. Despite its demonstrative nature, it was concluded that the proposed method was powerful in studying jawbone remodeling because it revealed a direct correlation of its rate with the lacunar density, as achieved by the analysis of the osteocyte lacunar network, and an inverse correlation with the local bone mineral density, as revealed with the Roschger approach.

Abstract
The aim of the investigation was to evaluate the insertion torque, pull-out torque and implant stability quotient (ISQ) of short implants (SI) and standard length implants (ST) inserted into linearly elastic and constitutive isotropic symmetry polyurethane foam blocks. Short dental titanium implants with a Cone Morse connection and a conical shape (test implants: Test Implant A—diameter 5.5 mm and length 6 mm) (Test Implant B—diameter 5.5 mm and length 5 mm) were used for the present in vitro investigation. ST implants (4 mm diameter and 10 mm length), with a Cone Morse connection and a conical shape, were used as Control Implant A and as Control Implants B. These two latter implants had a different macro design. A total of 20 implants (5 Test A, 5 Test B, 5 Control A and 5 Control B) were used for the present research. The results were similar when comparing the Test A and Test B implants. The test implants had very good stability in polyurethane 14.88–29.76 kgm3 density blocks. The insertion torque values were very high for both types of test implant (25–32 Ncm on 14.88 kgm blocks, and up to 45 Ncm in 29.76 kgm3 blocks). The pull-out test values were very similar to the insertion torque values. The ISQ values were significantly high with 75–80 in 14.88 kgm3 blocks, and 78–83 in 29.76 kgm3 blocks. No differences were found in the values of the Control A and Control B implants. In both these implants, the insertion torque was quite low in the 14.88 kgm3 blocks (16–28 Ncm). Better results were found in the 29.76 kgm3 blocks. The pull-out values for these control implants were slightly lower than the insertion torque values. High ISQ values were found in both control implants (57–80). When comparing SI and ST implants, the SI had a similar if not better performance in low quality polyurethane foam blocks (14.88–29.76 kgm), corresponding to D3 and D4 bone.

Oral Surg Oral Med Oral Pathol Oral Radiol 2019; 129:133-140. [PMID: 31606424 DOI: 10.1016/j.oooo.2019.08.018] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 08/06/2019] [Accepted: 08/25/2019] [Indexed: 12/31/2022]
Abstract
OBJECTIVE This study characterized histologic features of medication-related osteonecrosis of the jaw (MRONJ) through analysis of tissues from patients and healthy individuals. STUDY DESIGN Bone biopsies were collected from various infectious, inflammatory, and necrotic jaw diseases. Samples were divided into bone exposed to bisphosphonates or denosumab, as well as bisphosphonate-related osteonecrosis of the jaw (BRONJ), denosumab-related osteonecrosis of the jaw (DRONJ), and mixed necrosis, enabling us to identify features of single agent necrosis without influence from previous therapies. Hematoxylin and eosin (H&E), receptor activator of nuclear factor κ-Β ligand (RANKL), tartrate-resistant acid phosphatase (TRAP), osteoprotegerin, toluidine blue, CD14, and CD68 staining and micro-computed tomography (micro-CT) analysis were performed. Groups were compared by using analysis of variance (ANOVA). RESULTS In total, 156 bone samples were collected from 105 patients. MRONJ variants exhibited more infectious infiltration. Bisphosphonate (P < .001) and mixed necrosis (P = .002) demonstrated more RANKL- and TRAP-positive osteoclasts. Denosumab necrosis (P = .007), and bone exposed to bisphosphonates (P = .028) in combination with denosumab (P = .022) demonstrated significantly lower numbers of osteocytes per area. CD14 and CD68 positivity was increased for BRONJ (P = .008; P < .001, respectively). MRONJ variants exhibited the widest trabecular width and decreased medullary space to bone. No diminished vascular network in MRONJ samples was observed. CONCLUSIONS Histologic features differ among MRONJ variants, with oversuppressed bone turnover, dysfunctional bone resorption, and a disturbed osteocyte network as potential mechanisms of pathogenesis.

Abstract
Threads of dental implants with healing chamber configurations have become a target to improve osseointegration. This biomechanical and histometric study aimed to evaluate the influence of implant healing chamber configurations on the torque removal value (RTv), percentage of bone-to-implant contact (BIC%), bone fraction occupancy inside the thread area (BAFO%), and bone and osteocyte density (Ost) in the rabbit tibia after two months of healing. Titanium implants with three different thread configurations were evaluated: Group 1 (G1), with a conventional “v” thread-shaped implant design; Group 2 (G2), with square threads; and Group 3 (G3), the experimental group with longer threads (healing chamber). Ten rabbits (4.5 ± 0.5 kg) received three implants in each tibia (one per group), distributed in a randomized manner. After a period of two months, the tibia blocks (implants and the surrounding tissue) were removed and processed for ground sectioning to evaluate BIC%, BAFO%, and osteocyte density. The ANOVA one-way statistical test was used followed by the Bonferoni’s multiple comparison test to determine individual difference among groups, considering a statistical difference when p < 0.05. Histometric evaluation showed a higher BAFO% values and Ost density for G3 in comparison with the other two groups (G1 and G2), with p < 0.05. However, the RTv and BIC% parameters were not significantly different between groups (p > 0.05). The histological data suggest that the healing chambers in the implant macrogeometry can improve the bone reaction in comparison with the conventional thread design.

Long-lived murine osteocytes are embodied by craniofacial skeleton in young and old animals whereas they decrease in number in postcranial skeletons at older ages. Gerodontology 2018; 35:391-397.

Abstract
BACKGROUND Osteocytes are engaged in life-enduring processes such as bone remodelling, fracture healing or osseointegration of implants. Over age, ossification processes and regenerative capacity can greatly differ in mandible and femur. OBJECTIVE Mesenchymal stem cells from cranial and postcranial bones are of different embryologic origin. This may be the reason why the regenerative capacity differs between cranial and postcranial bones in old patients. It was hypothesised that different ageing patterns, reflected by osteocyte density, lacunar density and osteoid formation, exist between murine mandibles and femurs. MATERIAL AND METHODS Mandible and femur of young (4 months) and old (34-36 months old) male C57Bl/6 mice were histologically investigated to determine the number of lacunae occupied with osteocytes. Osteoid formation was revealed by Masson-Goldner staining, and the spatial distribution of BMP-2 synthesis was examined. RESULTS Over lifetime, the number of lacunae occupied with osteocytes only showed a modest decrease in mandibular bone (old 85.63%/young 91.12%) while greatly diverging in the femur (old 55.99%/young 93.28%). In equal measure, old femur exhibited less osteoid formation and decreased BMP-2 expression. CONCLUSION Tissue-specific conduct of bone ageing is moulded by osteocytic activities, which was found to vary between postcranial and craniofacial skeleton. The latter harbours long-lived osteocytes also in old animals which assures lifelong bone integrity. Preliminary concurring findings from a human cadaver, also presented in this contribution, provided a rationale for recommending the translatability to humans.

Abstract
BACKGROUND Long term use of glucocorticoids is one of the most common causes of secondary osteoporosis. Osteocyte, the most abundant cell type in bone, coordinates the function of osteoblast and osteoclast. This study evaluates the protective effect of alpinumisoflavone (AIF), a naturally occurring flavonoid compound, on dexamethasone (Dex)-induced apoptosis of osteocytes. METHODS MLO-Y4 cell was used as a cell model. The effect of AIF on the cell viability was assessed by MTT assay. Apoptosis of MYL-Y4 cells was determined by DNA fragment detection ELISA kit and flow cytometry. Intracellular ROS level was determined by DCFH-DA staining. mRNA and protein expression of target genes were determined by qRT-PCR and western blot, respectively. RESULTS AIF effectively protected MLO-Y4 cells against Dex-induced apoptosis, which was associated with attenuation of Dex-induced ROS generation in MLO-Y4 cells. Furthermore, our data indicated that the expression of NAD(P)H oxidase 2 (Nox2) was suppressed by AIF, which in turn mediated the attenuating effect on Dex-induced ROS generation and apoptosis in MLO-Y4 cells. Moreover, our results showed that AIF modulated the expression of Nox2 by activating AMPK signaling. CONCLUSION AIF activated AMPK-dependent Nox2 signaling pathway to suppress Dex-induced ROS production in cultured osteocytes, which might explain its anti-apoptotic effect. These results indicate that activation of AMPK pathway by AIF could have beneficial effects on bone damage induced by excessive oxidative stress and osteocyte apoptosis.

Abstract
There is currently no consensus regarding the survival rate of osseointegrated implants in patients with osteoporosis. A systematic review with meta-analysis was performed to evaluate the survival rate of implants in such patients. The PubMed/MEDLINE, Web of Science, Cochrane Library, and SciELO databases were used to identify articles published up to September 2016. The systematic review was performed in accordance with PRISMA/PICO requirements and the risk of bias was assessed (Australian National Health and Medical Research Council scale). The relative risk (RR) of implant failure and mean marginal bone loss were analyzed within a 95% confidence interval (CI). Fifteen studies involving 8859 patients and 29,798 implants were included. The main outcome of the meta-analysis indicated that there was no difference in implant survival rate between patients with and without osteoporosis, either at the implant level (RR 1.39, 95% CI 0.93-2.08; P=0.11) or at the patient level (RR 0.98, 95% CI 0.50-1.89; P=0.94). However, the meta-analysis for the secondary outcome revealed a significant difference in marginal bone loss around implants between patients with and without osteoporosis (0.18mm, 95% CI 0.05-0.30, P=0.005). Data heterogeneity was low. An increase in peri-implant bone loss was observed in the osteoporosis group. Randomized and controlled clinical studies should be conducted to analyze possible biases.

Abstract
PURPOSE OF REVIEW This review summarizes recent evidence on the impact of osteoporosis on periodontonlogy and implant dentistry, prevalence of diseases, pathophysiology and treatment outcomes. RECENT FINDINGS Patients with osteoporosis should be advised about the importance of returning for periodical periodontal maintenance as inadequate oral care may lead to a faster development of periodontitis. There is no definitive information on the development of bisphosphonate-related osteonecrosis of the jaw associated with dental implant therapy. Patients presenting severe periodontitis, undergoing intravenous bisphosphonate therapy (for long-term periods) and submitted to more invasive periodontal/peri-implant surgical procedures (that can promote superior dentoalveolar surgical trauma) might be advised about the possibility of developing bisphosphonate-related osteonecrosis of the jaw following dental therapy. Thus, individualized risk evaluation must be undertaken by both the medical and dental teams prior to any dental treatment. SUMMARY The most recent literature on the impact of osteoporosis on the periodontal and peri-implant tissues was reviewed to emphasize the importance of oral hygiene measures, and the combined medical/dental assessment of importance when osteoporotic patients are in need of dentoalveolar surgical procedures (e.g. tooth extraction and dental implant placement).
