Review
BACKGROUND/PURPOSE
Artificial intelligence (AI) has made deep inroads into dentistry in the last few years. The aim of this systematic review was to identify the development of AI applications that are widely employed in dentistry and evaluate their performance in terms of diagnosis, clinical decision-making, and predicting the prognosis of the treatment.
MATERIALS AND METHODS
The literature for this paper was identified and selected by performing a thorough search in the electronic data bases like PubMed, Medline, Embase, Cochrane, Google scholar, Scopus, Web of science, and Saudi digital library published over the past two decades (January 2000-March 15, 2020).After applying inclusion and exclusion criteria, 43 articles were read in full and critically analyzed. Quality analysis was performed using QUADAS-2.
RESULTS
AI technologies are widely implemented in a wide range of dentistry specialties. Most of the documented work is focused on AI models that rely on convolutional neural networks (CNNs) and artificial neural networks (ANNs). These AI models have been used in detection and diagnosis of dental caries, vertical root fractures, apical lesions, salivary gland diseases, maxillary sinusitis, maxillofacial cysts, cervical lymph nodes metastasis, osteoporosis, cancerous lesions, alveolar bone loss, predicting orthodontic extractions, need for orthodontic treatments, cephalometric analysis, age and gender determination.
CONCLUSION
These studies indicate that the performance of an AI based automated system is excellent. They mimic the precision and accuracy of trained specialists, in some studies it was found that these systems were even able to outmatch dental specialists in terms of performance and accuracy.

PURPOSE
Dental implant therapy is a common clinical treatment for missing teeth. However, the esthetic result is not as satisfactory as expected in some cases, especially in the anterior maxillary area. Poor esthetic results are caused by inadequate preparation of the hard and soft tissues in this area before treatment. The socket shield technique may be an alternative for a desirable esthetic outcome in dental implant treatments.
STUDY SELECTION
In the present systematic review, PubMed-Medline, Google Scholar, and ScienceDirect were searched for clinical studies published from January 2000 to December 2018.
RESULTS
Twenty studies were included, comprising one randomized controlled trial, two cohort studies, 14 clinical human case reports, and three retrospective case series. In total, 288 patients treated with the socket shield technique with immediate implant placement and follow-up between 3-60 months after placement were included. A quality assessment showed that 12 of the 20 included studies were of good quality. Twenty-six of the 274 (9.5%) cases developed complications or adverse effects related to the socket shield technique. Most studies reported implant survival without the complications (90.5%); most of the cases that were followed up for more than 12 months after implant placement achieved a good esthetic appearance. The failure rate was low without the complications, although there were some failures due to failed implant osseointegration, socket shield mobility and infection, socket shield exposure, socket shield migration, and apical root resorption.
CONCLUSIONS
The socket shield technique can be used in dental implant treatment, but it remains difficult to predict the long-term success of this technique until high-quality evidence becomes available.

Review
BACKGROUND
In addition to non-surgical root canal treatment or retreatment, apical surgery may be carried out to manage teeth with apical periodontitis. However, it is unclear which treatment option is more effective.
OBJECTIVE
To systematically review the effectiveness of apical surgery compared with non-surgical treatment or retreatment in terms of clinical and patient-related outcomes in teeth with apical periodontitis.
METHODS
A literature search of electronic databases, the grey literature, the reference lists of included articles and previous reviews, and a hand search of leading endodontic journals, was conducted. Randomised and non-randomised control trials, and longitudinal observational studies on patients undergoing surgical (treatment group) and non-surgical root canal treatment or retreatment (control group) of teeth with apical periodontitis were included. The risk of bias was appraised using the Cochrane risk-of-bias tool; ROBINS-I and the Newcastle-Ottawa Scale.
RESULTS
Five studies, consisting of two randomised clinical trials, two non-randomised clinical trials, and a retrospective cohort study, were included. The interobserver agreement was high and kappa correlation coefficient was good. In total 529 teeth were available for follow-up that varied from 6 months to 8.7 years. The overall risk of bias was high for four studies and raised some concerns in one study. Apical surgery showed seemly better results regarding periapical healing and less need for more and further intervention, although tooth survival was higher in the control group. Given the heterogeneity of the studies, meta-analysis was not possible.
DISCUSSION
Previous systematic reviews have conducted an indirect comparison by separately pooling the outcomes of studies analysing either non-surgical, or surgical, treatment. In this systematic review, only studies that compared both treatments were included. Most results of this and previous reviews were similar.
CONCLUSION
No treatment option showed clear superiority. However, to arrive at statistically supported conclusions there is a need for additional high-quality comparative trials.

Meta-Analysis
PURPOSE
Dynamic navigation is a technique that allows for the placement of dental implants using a computer-guided approach according to preoperative planning. Its accuracy has been assessed in several previous studies. The purpose of this study was to summarize data on implant placement accuracy using dynamic navigation, to synthesize the frequency of intraoperative complications and implant failures, and to compare this technique with static computer-guided surgery and a freehand approach.
MATERIALS AND METHODS
Electronic and manual literature searches until December 2019 were performed. The outcome variables were implant placement accuracy using dynamic navigation, accuracy differences between dynamic and static techniques and between dynamic and freehand techniques, intraoperative complications, and implant failures. Random-effects meta-analyses were performed.
RESULTS
A total of 32 studies were included; 29 reported accuracy values (2,756 implants), and 10 focused on complications and implant failures (1,039 implants). The pooled mean implant placement errors were 0.81 (95% CI: 0.677 to 0.943) mm at the entry point and 0.910 (95% CI: 0.770 to 1.049) mm at the apical point. The pooled mean vertical and angular deviations were 0.899 (95% CI: 0.721 to 1.078) mm and 3.807 (95% CI: 3.083 to 4.530) degrees. The navigation group showed significantly lower implant placement errors with respect to the freehand technique (P < .01) and similar accuracy values (P ≥ .05) compared with the static technique. The pooled prevalence of failures was 1% (95% CI: 0.00% to 2%).
CONCLUSION
Dynamic navigation provided small implant placement errors, comparable with those obtained using static computer-guided surgery, and can be considered a more accurate technique than conventional freehand surgery.

European Journal of Orthodontics Aug 2021Root resorption can be considered the most unfortunate complication of orthodontic treatment.
BACKGROUND
Root resorption can be considered the most unfortunate complication of orthodontic treatment.
OBJECTIVE
To evaluate the available evidence regarding orthodontically induced inflammatory root resorption (OIIRR).
SEARCH METHODS
A comprehensive literature search was conducted for the systematic reviews investigating OIIRR published up to 24 May 2020. This was accomplished using electronic databases: MEDLINE via OVID, EMBASE, AMED (Allied and Complementary Medicine Database), PubMed, and Web of Science. Any ongoing systematic reviews were searched using Prospero and a grey literature search was undertaken using Google Scholar and OpenGrey (www.opengrey.eu/). No language restriction was applied.
SELECTION CRITERIA
Only studies investigating OIIRR were included.
DATA COLLECTION AND ANALYSIS
Screening, quality assessment [using the AMSTAR 2 tool (A Measurement Tool to Assess Systematic Reviews)], and data extraction were performed by two authors independently. Information was categorized and narratively synthesized for the key findings from moderate and high-quality reviews.
RESULTS
A total of 2033 potentially eligible studies were identified. After excluding the non-relevant studies, 28 systematic reviews were included. Of which, 20 systematic reviews (71.5%) were of moderate and high-quality level of evidence. The incidence and severity of OIIRR increase with the fixed appliance, especially with heavy force, intrusion, torqueing movements, increased treatment duration, and treatment with extractions or with long apical displacement (particularly for maxillary incisors). There was insufficient evidence regarding most other treatment- and patient-related factors on OIIRR. Following all precautionary measures, pausing treatment and regular monitoring benefits patients with OIIRR.
CONCLUSIONS AND IMPLICATIONS
There is a limited number of high-quality studies in terms of OIIRR. The influence of fixed appliance on root resorption was noted; however, the cause and effect relationship between OIIRR and orthodontic biomechanics has not been confirmed. Avoiding heavy, continuous forces and a greater amount of apical displacement over a long duration of treatment is recommended. Precautionary measures should be carefully considered when treating patients with a high risk of OIIRR.

BACKGROUND
and studies have demonstrated the effectiveness of some irrigation protocols in reducing the bacterial load in the root canal system. However, standardized protocols have not yet been defined for the real clinical context due to many irrigation procedures available.
OBJECTIVE
To evaluate the clinical endodontic protocols and limitations of irrigating solutions in the disinfection of the root canal system in patients with apical periodontitis.
METHODS
PubMed, Scopus, Embase, Web of Science, and Cochrane databases were searched for randomized controlled trials (RCT) published until January 2021. Hand searching was also performed. Studies focused on evaluating the effectiveness of irrigating solutions and/or irrigation activation methods in reducing the bacterial load in the root canal system were considered. The Cochrane risk-of-bias tool for randomized trials (RoB2) was used to assess the quality of the studies.
RESULTS
Four hundred and twenty eight published articles were identified. After removing the duplicate studies and analyzing full texts, seven RCTs were selected. Two studies compared pure NaOCl with some combination of NaOCl with HEDP and MTAD. Two studies analyzed the antibacterial efficacy of NaOCl and chlorhexidine (CHX). Three studies compared conventional needle irrigation with different irrigation activation methods (PUI, XP-endo finisher, F-file activator, EndoVac activator). The review attained a satisfactory methodology. The main results of each included study were described.
DISCUSSION
Activation methods provide significantly higher biofilm reduction than conventional needle irrigation methods. Combinations of NaOCl with different chelating agents were ineffective in terms of antimicrobial, but it could potentially increase the risk of irrigant extrusion. However, the irrigating protocols were not carefully detailed, especially those regarding the irrigants application time or total volume. The existing literature lacks high-quality studies. The level of evidence is moderate.
CONCLUSIONS
The available data is too heterogeneous to compare and identify the superiority of specific valuable irrigation protocols in each clinical context. Application time, volume, and activation methods should be standardized to determine the optimal irrigating procedures to reduce the bacterial load and ensure higher predictability of the endodontic treatment.

Meta-Analysis
The long-term outcome of endodontic microsurgery (EMS) performed on root-filled teeth affected by post-treatment apical periodontitis (AP) has been a matter of debate, re-launched by the introduction of novel root-end filling materials which have been proven to improve the short-term outcome of EMS. The purpose of this systematic review and meta-analysis is to evaluate the clinical and radiographic long-term outcome of endodontic microsurgery in teeth diagnosed with secondary AP through radiographic evaluation. This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion and exclusion criteria were defined a priori to select the best longitudinal evidence. Only randomized clinical trials (RCT) and prospective clinical studies (PCS), with a follow-up ≥ 2-year, and exhibiting well-established clinical and radiographic outcome criteria, were selected. A total of 573 articles were obtained, from which 10 fulfill inclusion criteria: 6 PCS and 4 RCT. Meta-analysis showed a pooled proportion of success rate of 91.3%, from an overall amount of 453 treated teeth included in RCT; from overall 839 included teeth in PCS, a pooled success rate of 78.4% was observed, with the follow-up time ranging from 2 to 13-years. Survival rate outcomes varied from 79 to 100% for the same follow-up period. Five prognostic factors with influence on the outcome were disclosed: smoking habits, tooth location and type, absence/presence of dentinal defects, interproximal bone level, and root-end filling material. High success rates and predictable results can be expected when EMS is performed by trained endodontists, allowing good prognosis and preservation of teeth affected by secondary AP.

Comparison of the Success Rate of Mineral Trioxide Aggregate, Endosequence Bioceramic Root Repair Material, and Calcium Hydroxide for Apexification of Immature Permanent Teeth: Systematic Review and Meta-Analysis.
This systematic review aims to compare the success rate of Endosequence bioceramic root repair material (BCRRM), mineral trioxide aggregate (MTA), and calcium hydroxide for apexification of necrotic immature permanent teeth. Indexed Journals such as Google Scholar, PubMed, Scopus, Cochrane, Research Gate, Wiley Online Library, and other related journals were hand searched from inception till November 2020 and articles were selected for review based on PRISMA guidelines. Of the 410 studies that were identified, 150 articles were selected after title/abstract reading. After full-text reading and based on inclusion and exclusion criteria, 9 studies were finalized for systematic review. Clinical, radiographic success, and the time taken for apical barrier formation were reviewed. All the three materials had almost similar success rate in terms of clinical symptoms, but the time taken for apical barrier formation and also single visit treatment makes MTA and Endosequence BCRRM superior to calcium hydroxide. Studies comparing EndoSequence Root Repair Material and MTA are very limited and need further evaluation in the future.

Journal of Obstetrics and Gynaecology... Apr 2021To compare success and complication rates of apical suspension procedures for the surgical management of symptomatic uterine or vaginal vault prolapse. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To compare success and complication rates of apical suspension procedures for the surgical management of symptomatic uterine or vaginal vault prolapse.
TARGET POPULATION
Women with symptomatic uterine or vaginal vault prolapse seeking surgical correction.
OPTIONS
Interventions included abdominal apical reconstructive repairs (sacrocolpopexy, sacrohysteropexy, or uterosacral hysteropexy) via open, laparoscopic, or robotic approaches; vaginal apical reconstructive repairs (vault suspensions or hysteropexy, sacrospinous, uterosacral, iliococcygeus, McCall's, or Manchester types); and vaginal obliterative procedures (with or without uterus in situ). Individual procedures or broad categories of procedures were compared: (1) vaginal versus abdominal routes for reconstruction, (2) abdominal procedures for reconstruction, (3) vaginal procedures for reconstruction, (4) hysterectomy and suspension versus hysteropexy for reconstruction, and (5) reconstructive versus obliterative options.
OUTCOMES
The Urogynaecology Committee selected outcomes of interest: objective failure (obtained via validated pelvic organ prolapse [POP] quantification systems and defined as overall objective failure as well as failure rate by compartment); subjective failure (recurrence of bulge symptoms determined subjectively, with or without use of a validated questionnaire); reoperation for POP recurrence; complications of postoperative lower urinary tract symptoms (de novo or postoperative stress urinary incontinence; reoperation for persistent, recurrent, or de novo stress urinary incontinence; urge urinary incontinence; and voiding dysfunction); perioperatively recognized urinary tract injury (bladder or ureter); other complications (mesh exposure, defined as mesh being visible and exposed in the vagina, and non-sexual pelvic pain); and sexual function (de novo dyspareunia and sexual function score according to a validated questionnaire).
BENEFITS, HARMS, AND COSTS
This guideline will benefit patients seeking surgical correction of apical POP by improving counselling on surgical treatment options and possible outcomes. It will also benefit surgical providers by improving their knowledge of various surgical approaches. Data presented could be used to develop frameworks and tools for shared decision-making.
EVIDENCE
We searched Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase from 2002 to 2019. The search included multiple terms for apical POP surgical procedures, approaches, and complications. We excluded POP repairs using transvaginal mesh and studies that compared procedures without apical suspension. We included randomized controlled trials and prospective or retrospective comparative studies. We limited language of publication to English and French and accessibility to full text. A systematic review and meta-analysis was performed.
VALIDATION METHODS
The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations).
INTENDED USERS
Gynaecologists, urologists, urogynaecologists, and other health care providers who assess, counsel, and care for women with POP.
SUMMARY STATEMENTS
All statements refer to correction of apical vaginal prolapse in the short and medium term (up to 5 years), except when otherwise specified.

Review
BACKGROUND
Surgical root canal retreatment is required when peri-radicular pathosis associated with endodontically treated teeth cannot be treated by non-surgical root canal therapy (retreatment), or when retreatment was ineffective, not feasible or contraindicated. Endodontic failures maybe happen when irritants remain within the confines of the root canal, or when an extra-radicular infection cannot be eradicated by orthograde root canal treatment. Following enhanced microsurgical techniques in the last years, the success rates of surgical root canal retreatment have improved considerably.
OBJECTIVE
The aim of this systematic review is to gather updated data in regard to the surgical root canal (retrograde) retreatment to heal the periapical lesions.
MATERIALS AND METHODS
The electronic databases PubMed and Google Scholar were searched in this review using specific inclusion and exclusion criteria. The search was performed in June 2019 and updated in November 2019. Among 3900 studies, 10 studies satisfied the eligibility criteria and were included in the review to be analyzed.
RESULTS
The 10 studies showed the importance of surgical root canal retreatment as a treatment option in removing infections within the root canal system and its efficiency in periapical tissue healing. These studies investigated different aspects of healing of periapical lesion after surgical (retrograde) retreatment including success rates, follow-up duration, and updated studies in surgical (retrograde) retreatment.
CONCLUSIONS
Surgical root canal (retrograde) retreatment demonstrates its efficiency in reducing the period needed for healing of the periapical lesions in short-term follow-up compared to conventional orthograde retreatment.
