Meta-Analysis Review
Effectiveness of pre-alveolar bone graft orthodontics for patients with non-syndromic complete unilateral cleft lip, alveolus and palate: A systematic review and meta-analysis.
UNLABELLED
The aim of this systematic review was to compare the effectiveness of pre-alveolar bonegraft (ABG) orthodontics with no orthodontic treatment for patients with non-syndromic unilateral cleft lip, alveolus and palate. All relevant studies from 1946 to October 30, 2022, were identified using several sources including The Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), LILACS, Scopus, EMBASE, MEDLINE (Ovid) and EPUB ahead of publications and non-indexed citations. Randomized Controlled Trials (RCT) and Controlled Clinical Trials (CCT) were included.
POPULATION
Non-syndromic complete unilateral cleft lip, alveolus and palate patients who have had ABG surgery.
INTERVENTION
Orthodontics prior to ABG. Comparison: No orthodontic treatment prior to ABG.
PRIMARY OUTCOME
Successful eruption of permanent canines. All articles were screened for the title, abstract and full text independently and in duplicate by 2 reviewers. The quality assessment of RCT was performed using Cochrane's risk of bias tool and the CCT was assessed using ROBINS-I tool. Of the 904 studies retrieved in the search, one RCT and one CCT were included. Both studies were judged as high risk of bias. The results from one study showed a statistically significant increase in bone volume and decreased bone defect post-ABG in the orthodontic treatment group. However, there was no difference with respect to other variables. Both included studies were of low quality. There is not enough evidence to recommend orthodontic treatment pre-ABG for patients with complete unilateral cleft lip, alveolus and palate. Future high-quality studies are required to inform patients and clinicians about the effectiveness of pre-graft orthodontic treatment.

Meta-Analysis
BACKGROUND
Autogenous particulate dentin (APD) has been used as a bone graft material for bone augmentation, but the specifics of its effect on alveolar ridge preservation (ARP) are uncertain. The aim of this study was to investigate the clinical and histomorphometric performance of APD compared with blood clot healing or other grafted materials in ARP.
METHODS
MEDLINE, Embase, Web of Science, Scopus and the Cochrane Library and citation databases were searched until August 2, 2023 to identify randomized controlled trials that employed APD for ARP. Two independent meta-analyses were performed based on the different control groups (Group I: blood clot healing; Group II: other grafted materials). Weighted or mean differences (MDs) and corresponding 95% confidence intervals (CIs) were calculated. The protocol was prospectively registered with PROSPERO (CRD42023409339).
RESULTS
A total of 238 records were identified, of which ten studies with 182 participants were included. The meta-analysis indicated that APD resulted in fewer changes in horizontal ridge width (Group I: MD = 1.61, 95% CI 0.76-2.46; Group II: MD = 1.28, 95% CI 1.08-1.48) and labial bone height (Group I: MD = 1.75, 95% CI 0.56-2.94; Group II: P < .05) than the control treatments. Regarding histomorphometry, APD yielded a satisfactory proportion of vital bone area (MD = 10.51, 95% CI 4.70-16.32) and residual material area (MD = -8.76, 95% CI -12.81 to -4.71) in Group II, while there was no significant difference in Group I. Moreover, none of the secondary outcomes were significantly differed between groups.
CONCLUSION
Within this study limitations, APD effectively maintained the horizontal and vertical dimensions of the extraction sockets and exhibited favorable osteogenic properties and degradation capacity. Further well-designed randomized controlled trials with larger samples and longer follow-up periods are needed to evaluate whether APD is superior to other substitutes for ARP.

Meta-Analysis
OBJECTIVES
To assess whether in animals or patients with ≥ 1 tooth extracted, hyaluronic acid (HyA) application results in superior healing and/or improved complication management compared to any other treatment or no treatment.
MATERIALS AND METHODS
Three databases were searched until April 2022. The most relevant eligibility criteria were (1) local application of HyA as adjunct to tooth extraction or as treatment of alveolar osteitis, and (2) reporting of clinical, radiographic, histological, or patient-reported data. New bone formation and/or quality were considered main outcome parameters in preclinical studies, while pain, swelling, and trismus were defined as main outcome parameters in clinical studies.
RESULTS
Five preclinical and 22 clinical studies (1062 patients at final evaluation) were included. In preclinical trials, HyA was applied into the extraction socket. Although a positive effect of HyA was seen in all individual studies on bone formation, this effect was not confirmed by meta-analysis. In clinical studies, HyA was applied into the extraction socket or used as spray or mouthwash. HyA application after non-surgical extraction of normally erupted teeth may have a positive effect on soft tissue healing. Based on meta-analyses, HyA application after surgical removal of lower third molars (LM3) resulted in significant reduction in pain perception 7 days postoperatively compared to either no additional wound manipulation or the application of a placebo/carrier. Early post-operative pain, trismus, and extent of swelling were unaffected.
CONCLUSIONS
HyA application may have a positive effect in pain reduction after LM3 removal, but not after extraction of normally erupted teeth.
CLINICAL RELEVANCE
HyA application may have a positive effect in pain reduction after surgical LM3 removal, but it does not seem to have any impact on other complications or after extraction of normally erupted teeth. Furthermore, it seems not to reduce post-extraction alveolar ridge modeling, even though preclinical studies show enhanced bone formation.

The International Journal of Oral &... Oct 2023To evaluate the peri-implant outcomes of customized healing abutments (CstHA) placed on dental implants inserted in fresh tooth extraction sockets.
PURPOSE
To evaluate the peri-implant outcomes of customized healing abutments (CstHA) placed on dental implants inserted in fresh tooth extraction sockets.
MATERIALS AND METHODS
The study was registered on PROSPERO: CRD42022304320. A systematic search in PubMed, Scopus, and Web of Science was conducted between April 2022 and October 2022 to identify clinical studies involving immediate implant surgery associated with CstHA placement. The Joanna Briggs Institute Critical Appraisal and RoB2 tool were performed for the risk of bias analysis.
RESULTS
A total of 12 studies were included, most of them with low risk of bias. Four studies compared CstHA vs conventional healing abutments (CnvtHA), two compared CstHA vs cover screw and collagen matrix (CMa), and six were clinical case series. For the CstHA vs CnvtHA comparison, favorable results were observed for CstHA considering papilla maintenance and probing depth, yet the mean marginal bone level was statistically similar between CstHA and CnvtHA. CstHA showed advantages when compared to CMa for total bone volume, papilla height, and midfacial mucosa maintenance. Significantly less horizonal bone loss was reported when using CstHA compared with CMa. Horizontal and vertical bone loss was observed in a few (or no) sites in the case series using CstHA.
CONCLUSIONS
CstHA provides favorable peri-implant response because in general it does not result in a significant loss of soft and hard tissues.

BACKGROUND
Dental autotransplantation (DAT) is defined as the replacement or direct transfer of an impacted, semi-impacted or erupted tooth to a donor site, either to a post-extraction socket or to a surgically created socket within the same individual. The use of new technological advances, such as 3-D dental models based on computer-aided design, among others, have been reported to improve the success rate of DAT. Therefore, we aimed to perform a systematic review to explore the possible benefits that the use of these innovative techniques can provide when applied to DAT.
MATERIAL AND METHODS
The literature search was conducted in PubMed, Scopus, and Web of Science databases following the PRISMA guidelines. The research question was: "Are computerized technological advancements a useful tool for improving the success of third molar autotransplantation technique?
RESULTS
The initial literature search identified 195 articles, of which only 11 were included for qualitative analysis. All studies used 3D dental models based on computer-aided design data. Surgical guides and stereolithographic models were used by 4 and 1 study respectively. A total of 91 transplanted teeth were evaluated, out of which only 88 were considered within the parameters of clinical success (96.7%). Only 7 out of the 11 articles reported the specific autotransplanted tooth, being mandibular third molars the most prevalent autotransplanted teeth.
CONCLUSIONS
Although the application of new technologies for DAT increases the success rate of this technique, further primary studies are still needed to address long-term teeth survival rates and complications. The cost and availability to implement the integration of these techniques to DAT may be a variable to consider, as this can be a limitation for some patients or for low-income countries.

Evidence-based Dentistry Dec 2023A systematic review and meta-analysis of observational studies. (Meta-Analysis)
Meta-Analysis
DESIGN
A systematic review and meta-analysis of observational studies.
DATA SOURCES
Electronic search included PubMed, Scopus, and Web of Science databases up to March 2022 using appropriate keywords.
SELECTION CRITERIA
The review included all observational studies (case-control, cohort and cross-sectional studies) published in English after 2000, comparing the prevalence of dry socket between smokers and non-smokers after simple or surgical tooth extraction. Exclusion criteria included patients with other post-extraction complications, prevalence of different risk factors, and unrelated study designs (literature reviews, case reports, expert opinion, and conference reports).
DATA EXTRACTION AND SYNTHESIS
Two independent investigators screened the records (by title, abstract, and full text), and selected the eligible studies according to the predefined criteria. Collected data from each study included author name and country, year of publication, gender and age of patients, smoking status, inclusion and exclusion criteria, medical history and oral hygiene, prevalence of dry socket, type of tooth and extraction technique, symptoms and treatment. Risk of bias was assessed according to the (NHLBI, NIH) Quality Assessment Tool For Observational Cohort and Cross-Sectional Studies, while the level of evidence was assessed using the classification of the Oxford Centre for Evidence-Based Medicine levels for diagnosis. Two independent reviewers conducted the assessments, and any disagreements were addressed through discussion.
RESULTS
Eleven studies from ten different countries representing a total of 10,195 patients (3007 smokers and 7188 non-smokers) were included in the final analysis. Nine studies were classified as having "good" quality and two as "intermediate," while all of the studies have the third or fourth level of evidence (through 5-graded scale). The prevalence of dry socket in smokers was about 13.2% (95% CI: 5.8-23.1%) and in non-smokers about 3.8% (95% CI: 2.1-6.0%). Meta-analysis showed that regular tobacco smoking was associated a more than 3-fold increase in the odds of dry socket after tooth extraction.
CONCLUSION
Despite heterogeneity among the included studies (different age groups and types of teeth extracted), there was a consistent association between cigarette smoking and an elevated risk of developing dry socket post tooth extraction.

Meta-Analysis Review
AIM
The present systematic review aimed to identify and summarize the clinical, radiographic, and histological outcomes of alveolar ridge preservation using bone xenografts and absorbable sealing materials compared with spontaneous healing in the esthetic zone.
MATERIALS AND METHODS
Randomized clinical trials (RCTs) fulfilling specific eligibility criteria were included. Two review authors independently searched for eligible studies, extracted data from the published reports and performed the risk of bias assessment (RoB 2 tool). Study results were summarized using random effects meta-analyses.
RESULTS
Thirteen articles concerning 10 RCTs were included, involving a total of 357 participants. Most of studies were considered as "low" risk of bias. Meta-analyses indicated less horizontal (difference in means-MD = 1.88 mm; p < 0.001), vertical mid-buccal (MD = 1.84 mm; p < 0.001) and vertical mid-lingual (MD = 2.27 mm; p < 0.001) bone resorption in alveolar ridge preservation compared to spontaneous healing as assessed clinically. Bone changes assessed radiographically showed consistent results in terms of horizontal (at 1 mm: MD = 1.84 mm, p < 0.001), vertical mid-buccal (MD = 0.95 mm; p < 0.001) and mid-lingual (MD = 0.62 mm; p = 0.05) resorption. Part of the bone resorption in the spontaneous healing group was compensated by soft-tissues, since the observed differences between groups in linear ridge reduction evaluated through cast models superimposition were smaller (MD = 0.52 mm; p < 0.001).
CONCLUSIONS
Alveolar ridge preservation with xenogeneic bone substitutes and non-autogenous resorbable socket sealing materials is efficacious in reducing post-extraction bone and ridge changes in the esthetic region.

Meta-Analysis Review
Clinicians frequently prescribe systemic antibiotics after lower third molar extractions to prevent complications such as surgical site infections and dry socket. A systematic review of randomised clinical trials was conducted to compare the risk of dry socket and surgical site infection after the removal of lower third molars with different prophylactic antibiotics. The occurrence of any antibiotic-related adverse event was also analysed. A pairwise and network meta-analysis was performed to establish direct and indirect comparisons of each outcome variable. Sixteen articles involving 2158 patients (2428 lower third molars) were included, and the following antibiotics were analysed: amoxicillin (with and without clavulanic acid), metronidazole, azithromycin, and clindamycin. Pooled results favoured the use of antibiotics to reduce dry socket and surgical site infection after the removal of a lower third molar, with a number needed to treat of 25 and 18, respectively. Although antibiotic prophylaxis was found to significantly reduce the risk of dry socket and surgical site infection in patients undergoing lower third molar extraction, the number of patients needed to treat was high. Thus, clinicians should evaluate the need to prescribe antibiotics taking into consideration the patient's systemic status and the individual risk of developing a postoperative infection.

Meta-Analysis Review
BACKGROUND
Corticosteroids are used to manage pain after surgical tooth extractions. The authors assessed the effect of corticosteroids on acute postoperative pain in patients undergoing surgical tooth extractions of mandibular third molars.
TYPES OF STUDIES REVIEWED
The authors conducted a systematic review and meta-analysis. The authors searched the Epistemonikos database, including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and the US clinical trials registry (ClinicalTrials.gov) from inception until April 2023. Pairs of reviewers independently screened titles and abstracts, then full texts of trials were identified as potentially eligible. After duplicate data abstraction, the authors conducted random-effects meta-analyses. Risk of bias was assessed using Version 2 of the Cochrane Risk of Bias tool and certainty of the evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation approach.
RESULTS
Forty randomized controlled trials proved eligible. The evidence suggested that corticosteroids compared with a placebo provided a trivial reduction in pain intensity measured 6 hours (mean difference, 8.79 points lower; 95% CI, 14.8 to 2.77 points lower; low certainty) and 24 hours after surgical tooth extraction (mean difference, 8.89 points lower; 95% CI, 10.71 to 7.06 points lower; very low certainty). The authors found no important difference between corticosteroids and a placebo with regard to incidence of postoperative infection (risk difference, 0%; 95% CI, -1% to 1%; low certainty) and alveolar osteitis (risk difference, 0%; 95% CI, -3% to 4%; very low certainty).
PRACTICAL IMPLICATIONS
Low and very low certainty evidence suggests that there is a trivial difference regarding postoperative pain intensity and adverse effects of corticosteroids administered orally, submucosally, or intramuscularly compared with a placebo in patients undergoing third-molar extractions.

Meta-Analysis Review
OBJECTIVES
To investigate the histomorphometric changes occurring in alveolar ridge preservation (ARP) based on the use of different plasma concentrates (PCs) in randomized clinical trials (RCT). There is controversy whether the placement of PCs in ARP is effective in the formation of new bone.
MATERIALS AND METHODS
A systematic review search was conducted in PubMed, Scopus, Web of Science, and Cochrane Database to answer the PICO question: In patients undergoing tooth extraction followed by ARP, do PCs alone in the post-extraction socket in comparison with spontaneous healing improve new vital bone formation percentage in histomorphometric analysis after more than 10 weeks? The risk of bias was assessed and a meta-analysis was conducted.
RESULTS
Of 3809 results, 8 studies were considered suitable for inclusion. A total of 255 teeth were extracted in 250 patients. Regarding the PCs used, ARP was performed with platelet- and leukocyte-rich fibrin (L-PRF) in 120 sockets, and with pure platelet-rich plasma (P-PRP) in 31 sockets and 104 sockets were controlled. PCs improved new bone formation in ARP with respect to the spontaneous healing group (SMD = 1.77, 95%C.I. = 1.47-2.06, p-value < 000.1). There were no differences between the different PCs (L-PRF and P-PRP).
CONCLUSION
The results of this meta-analysis support the efficacy of the use of PCs in new bone formation in ARP. With respect to the different types of PCs studied, no differences were observed.
CLINICAL RELEVANCE
When planning implant surgery after tooth extraction, treatment with PCs should be considered for ARP. Any PC increases new bone formation compared to spontaneous healing.
