Review
The aim of this systematic review is to describe and identify the prospects of β-Tricalcium Phosphate (β-TCP) as an alveolar bone grafting (ABG) material in cleft lip/palate (CL/P) or alveolar bone cleft defects. A systematic review protocol based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA 2020) was drafted. The literature search was conducted using MEDLINE/PubMed, Web of Science/ISI Web of Knowledge, Scopus, and the Cochrane Library, with English as the inclusion criterion and no publication year limits. The keywords yielded a total of 5824 publications. After removing duplicates and non-English articles, there were 3196 suitable articles available for evaluation. Subsequently, 1315 studies remained after reviewing titles and abstracts. Furthermore, 85 full articles were assessed for eligibility. After reading the complete texts of those papers, 20 were eventually selected that matched the inclusion requirements. Thirteen out of the twenty studies included in this systematic review were deemed to have a low risk of bias; one had a high risk of bias; and six had a moderate risk of bias due to not reporting randomization. β-TCP, when used as an ABG material, is biocompatible, visible, practical, offers a less invasive procedure, and does not interfere with orthodontic treatment. Synthetic β-TCP for ABG can be an alternative to autologous bone grafts under certain terms and conditions. The efficacy of β-TCP for ABG in CL/P or alveolar bone cleft defects can be enhanced through a tissue engineering approach that combines β-TCP with growth factors, mesenchymal stem cells, or other graft materials, along with modifications to β-TCP's physical properties.

Review
UNLABELLED
Textilomas, gossypibomas, muslinomas and gauzomas, otherwise collectively known as Retained Non-absorbable Hemostatic Material (RNHM), are surgical materials such as cotton or gauze pads that are accidentally retained in the surgical bed post-operatively. They may present acutely with signs of infection or may rarely remain chronic and asymptomatic; the latter posing a significant challenge to clinical and imaging diagnosis. Textilomas are not routinely reported due to their medicolegal implications and are usually encountered fortuitously. Here, we report a case of an individual who presented with a non-specific lower backache, had a remote history of lumbar discectomy and in whom a textiloma at the postoperative site was seen to mimic a soft-tissue mass on imaging. In addition, we review current, up-to-date literature on delayed presentations of such retained materials after surgery of the lumbar spine.
CASE REPORT
A 43-year-old male presented with pain in his right lower back and gluteal region. He had undergone an L4-L5 discectomy 11 years ago, remained asymptomatic since, and noticed an insidious, worsening pain a week before presentation. Mild tenderness was elicited over the region of pain. A clinical diagnosis of L4-L5 extraforaminal disc prolapse with deep surgical site infection was made. Ultrasound showed an iso-to-hyperechogenic lesion in the right lower paraspinal region. MRI showed a very well-defined, ovoid T1-hypointense and T2-iso-hypointense lesion in the deep posterior paraspinal region of the L4/5 level adjacent to right laminar process of L4 vertebra. The lesion caused scalloping and chronic erosion of the laminar process. No obvious air pockets were present. The features of infection, like soft tissue oedema and collection, were absent. Based on imaging, differentials of nerve sheath tumour and gossipybomas was made. Open wound exploration was performed, which showed a wad of gauze within the right L4-L5 interlaminar space, with thin surrounding granulation tissue The L4-L5 disc and exiting nerve root were normal. The mass was removed, local washing was done and wound was closed.
CONCLUSION
Though unfortunate and relatively rare, the possibility of a textiloma must be considered among the differential diagnoses of a mass in the spinal region in the event of prior surgery, no matter how remote the history. Clinical presentation may vary, but the imaging appearance is largely consistent and can be relied upon to prevent unnecessary investigation and facilitate early surgical removal of the offending retained material.

Review
Tick-borne encephalitis (TBE) is an infection caused by the Tick-borne encephalitis virus (TBEv) and it is common in Europe. The virus is predominantly transmitted by ticks, but other non-vectorial modes of transmission are possible. This systematic review synthesises the epidemiological impact of non-vectorial modes of TBEv transmission in Europe. 41 studies were included comprising of 1308 TBE cases. Alimentary (36 studies), handling infected material (3 studies), blood-borne (1 study), solid organ transplant (1 study) were identified as potential routes of TBEv transmission; however, no evidence of vertical transmission from mother to offspring was reported (2 studies). Consumption of unpasteurised milk/milk products was the most common vehicle of transmission and significantly increased the risk of TBE by three-fold (pooled RR 3.05, 95% CI 1.53 to 6.11; 4 studies). This review also confirms handling infected material, blood-borne and solid organ transplant as potential routes of TBEv transmission. It is important to tracing back to find the vehicle of the viral infection and to promote vaccination as it remains a mainstay for the prevention of TBE.

Review
Background: Dental implants are widely used and in order to answer to esthetic demands, zirconia has been introduced as an abutment material as an alternative to titanium. Several studies have been published on this topic, but the results have been often inconsistent. The objective of the present study is to systematically analyze the existing literature comparing clinical outcomes of titanium and zirconia implant abutments. The study was designed as a systematic review of systematic reviews. Methods: This systematic review is in accordance with the Transparent Reporting of Systematic Reviews and Meta-analyses. A MEDLINE/PubMed, Cochrane Database of Systematic Reviews and SCOPUS literature search was performed up to and including June 2021. Data were extracted independently by two reviewers and tAMSTAR2 was used to assess the quality of the systematic reviews. Results: The electronic search identified 1146 papers, and 175 duplicates were removed. After manual screening, 954 studies were excluded and the final analysis was conducted on 11 papers. Both mechanical and esthetic outcomes and biological complications were analyzed. Conclusions: It can be concluded that titanium abutments have a better mechanical resistance than zirconia ones. Plaque accumulation is reported to be slightly higher on titanium but without any significant inflammatory process. The esthetic outcomes seem to be more related to the thickness (>3 mm) of the soft tissues than to the abutment material.

Review
Biosensors are a simple, low-cost, and reliable way to detect pesticides in food matrices to ensure consumer food safety. This systematic review lists which nanomaterials, biorecognition materials, transduction methods, pesticides, and foods have recently been studied with biosensors associated with analytical performance. A systematic search was performed in the Scopus ( = 388), Web of Science ( = 790), and Science Direct ( = 181) databases over the period 2016-2021. After checking the eligibility criteria, 57 articles were considered in this study. The most common use of nanomaterials (NMs) in these selected studies is noble metals in isolation, such as gold and silver, with 8.47% and 6.68%, respectively, followed by carbon-based NMs, with 20.34%, and nanohybrids, with 47.45%, which combine two or more NMs, uniting unique properties of each material involved, especially the noble metals. Regarding the types of transducers, the most used were electrochemical, fluorescent, and colorimetric, representing 71.18%, 13.55%, and 8.47%, respectively. The sensitivity of the biosensor is directly connected to the choice of NM and transducer. All biosensors developed in the selected investigations had a limit of detection (LODs) lower than the Codex Alimentarius maximum residue limit and were efficient in detecting pesticides in food. The pesticides malathion, chlorpyrifos, and paraoxon have received the greatest attention for their effects on various food matrices, primarily fruits, vegetables, and their derivatives. Finally, we discuss studies that used biosensor detection systems devices and those that could detect multi-residues in the field as a low-cost and rapid technique, particularly in areas with limited resources.

Review
OBJECTIVE
This systematic review aims to assess the efficacy chlorhexidine chip as an adjunctive therapy of scaling and root planning on periodontal disease treatment.
MATERIAL AND METHODS
This study follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) and was registered in the PROSPERO database (CRD42019148221). The search was performed in PubMed/MEDLINE, Scopus, and Cochrane databases until April 2020. The PICO question was: "Is the chlorhexidine chip (CHX) effective as an adjunctive therapy of scaling and root planning on periodontal disease treatment?". Inclusion criteria involved: randomized controlled clinical trials, with a minimum of 15 patients included on the sample and each patient has two sites of probing depth of ≥5 mm; The minimum follow up was at least 1 months of follow-up and the outcomes present in the studies probing depth (PD), plaque index (PI) and clinical attachment level (CAL) after scaling and root planning (SRP).
RESULTS
After searching the databases, 13 articles were selected for qualitative and 8 for quantitative analysis. Were included 427 patients, with a mean age of 45.6 years. The results shown that the association of chlorhexidine chips to scaling and root planning reduce periodontal pocket depths ( < 0.00001; MD -0.77 [CI -1.0 to -0.55]; I = 23%, = 0.24), gain on the clinical attachment level ( < 0.0001; MD -0.57 [CI -0.86 to -0.27]; I = 33%, P = 0.18P < 0.0001) and reduction on plaque index (P = 0.04; MD -0.23 [CI -0.45 to -0.01]; I = 91%, P < 0.00001).
CONCLUSIONS
Thus, we can conclude that chlorhexidine chip when used associated to scaling and root planning promoted a significant improvement the reduction of periodontal diseases.

Meta-Analysis
BACKGROUND
Rhinoplasty is one of the most common operations in plastic and aesthetic surgery. Both solid silicone material and autologous cartilage (AC) tissue have their individual advantages and disadvantages. In this meta-analysis, the efficacy, complication rate of rhinoplasty with AC and silicone material were comprehensively analyzed and compared.
METHODS
The databases Medline, Embase, PubMed, China National Knowledge Infrastructure (CNKI) and Wanfang were searched by rapid matching of keywords to obtain randomized controlled trials related to AC rhinoplasty or silicone filled rhinoplasty, which were analyzed using the software Stata 16.0 after screening and quality assessment.
RESULTS
A total of 1,233 patients undergoing rhinoplasty from 7 articles were included in the study. Meta-analysis showed that rhinoplasty with AC would gain more satisfaction [risk ratio (RR) =1.11; 95% confidence interval (CI): (1.02, 1.21); Z=2.413; P=0.016]. would reduce the complication rate [RR =0.34; 95% CI: (0.22, 0.52); Z=-5.010; P<0.0001], and resulting in less secondary surgery rate [RR =0.34; 95% CI: (0.18, 0.64); Z=-3.363; P=0.001] comparing to silicone prosthesis (SP) material.
DISCUSSION
In rhinoplasty, the use of AC material gains more satisfaction, has less total complication rate, and results in less secondary surgery rate than silicone material. But based on the heterogeneity and publication bias in the studies, this topic still needs to be further explored by including more high-quality studies.

Review
(1) Aim: To perform a systematic review of the literature on the biocompatibility of root canal sealers that encompasses the various types of sealers that are commercially available as well as both in vitro and in vivo evidence. (2) Methods: This systematic review has been registered in PROSPERO (ID 140445) and was carried out according to PRISMA guidelines using the following databases: PubMed, Cochrane Library, ClinicalTrials.gov, Science Direct, and Web of Science Core Collection. Studies published between 2000 and 11 June 2019 that evaluated cytotoxicity (cell viability/proliferation) and biocompatibility (tissue response) of root canal sealers were included. (3) Results: From a total of 1249 studies, 73 in vitro and 21 in vivo studies were included. In general, studies suggest that root canal sealers elicit mild to severe toxic effects and that several factors may influence biocompatibility, e.g., material setting condition and time, material concentration, and type of exposure. Bioactive endodontic sealers seem to exhibit a lower toxic potential in vitro. (4) Conclusions: The available evidence shows that root canal sealers exhibit variable toxic potential at the cellular and tissue level. However, the methodological heterogeneity among studies included in this systematic review and the somewhat conflicting results do not allow a conclusion on which type of sealer presents higher biocompatibility. Further research is crucial to achieve a better understanding of the biological effects of root canal sealers.

Meta-Analysis Review
OBJECTIVES
For a conventional indirect restoration, temporary cementation inevitably contaminated collapsed dentin collagen. The purpose of this review was to evaluate the optimal strategy for minimizing its negative effects.
MATERIAL AND METHODS
Databases such as PubMed, Web of Science, EMBASE, and the Cochrane Library were searched for in vitro studies, involving the influence of immediate dentin sealing (IDS), different temporary cements, and their removal strategies on dentin bond strength. The meta-analysis used the inverse variance method with effect method of the standardized mean difference and statistical significance at p ≤ 0.05. The I value and the Q-test were used to assess the heterogeneity.
RESULTS
A total of 14 in vitro trials were subjected to the meta-analysis. Within the study's limitations, we assumed that IDS eliminated the negative effects of temporary bonding, achieving the comparable immediate bond strength with the control (p = 0.46). In contrast, under delayed dentin sealing (DDS), temporary cementation statistically decreased bond strength (p = 0.002). Compared with resin-based and non-eugenol zinc oxide cements, polycarboxylate and calcium hydroxide cements performed better on bond strength with no statistical difference from the control group (p > 0.05). Among the removal methods of temporary cements, the AlO abrasion restored the decreased bond strength (p = 0.07) and performed better than hand instruments alone (p = 0.04), while pumice removal slightly reduced the bond strength in contrast with the control group (p = 0.05, 95% CI = - 1.62 to 0).
CONCLUSIONS
The choices of IDS, polycarboxylate and calcium hydroxide temporary cements, AlO abrasion removal method were feasible and efficient to enhance the bond strength.
CLINICAL RELEVANCE
It is worthwhile applying IDS technique, polycarboxylate and calcium hydroxide temporary cements during indirect restoration. The AlO abrasion of cleaning dentin can minimize the negative effects of temporary cement.

Maxillary Sinus Floor Augmentation with Autogenous Bone Graft Compared with a Composite Grafting Material or Bone Substitute Alone: a Systematic Review and Meta-Analysis Assessing Volumetric Stability of the Grafting Material.
OBJECTIVES
Test the hypothesis of no difference in the volumetric stability of the grafting material following maxillary sinus floor augmentation with autogenous bone graft compared with composite grafting material or bone substitute alone applying the lateral window technique.
MATERIAL AND METHODS
MEDLINE (PubMed), Embase, Cochrane library and hand-search of relevant journals were conducted. Human studies published in English until the 9 of October 2020 were included. Outcome measures included three-dimensional volumetric changes of the grafting material and potential predictive parameters. Volumetric changes were evaluated by descriptive statistics and meta-analysis including 95% confidence interval.
RESULTS
Electronic search and hand-searching resulted in 102 entries. Four randomized controlled trials with unclear risk of bias fulfilled the inclusion criteria. The volumetric stability of the grafting material was significantly improved by mixing autogenous bone graft with a non-resorbable xenograft compared with autogenous bone graft. Meta-analyses assessing absolute and relative volumetric changes demonstrated no significant differences between autogenous bone graft compared with allogeneic bone graft, synthetic biomaterials combined with autogenous bone graft or used alone. Association between volumetric changes of the grafting material and potential predictive parameters were not assessed in the included studies.
CONCLUSIONS
Volumetric reduction of the augmented area seems inevitable following maxillary sinus floor augmentation regardless of the grafting material. The volumetric stability of autogenous bone graft is improved with addition of xenograft compared with autogenous bone graft. However, conclusions drawn from this systematic review should be interpreted with caution since only four studies using three-dimensional radiographic measurements were included.
