Review
AIM
The purpose of this systematic review was to identify and review the literature concerning natal and neonatal teeth.
STUDY DESIGN AND METHODS
The literature search was conducted using several databases. Specific terms were used in the search, which includes articles from 1950 to 2011, supplementary searching by hand was also used. Relevant studies were selected according to predetermined inclusion criteria.
RESULTS
Studies meeting the inclusion criteria were only found with regards to prevalence and management of natal and neonatal teeth. Prevalence ranged from near 0 to 1:10 while extraction or maintenance of teeth comprised the management options.
CONCLUSION
There is significant need for further research, under specific scientific preconditions, to provide an evidence-based treatment for patients and to determine the prevalence of natal and neonatal teeth more precisely.

Meta-Analysis Review
OBJECTIVES
This meta-analysis review aims to answer two questions: 1) What is the effectiveness of hydrophilic resin-based sealant (RBS) in preventing/arresting pits and fissures caries in permanent teeth, and 2) What is the retention rate of a hydrophilic RBS as compared to alternative treatments.
DATA
Randomized control trials investigating the efficacy of hydrophilic RBS compared to any other (placebo) treatment for permanent teeth. Outcomes were retention rate and caries prevention/arresting.
SOURCES
A systematic search for eligible studies was conducted on six electronic databases (Scopus, Ovid MEDLINE, Ovid Embase, Cochrane; Web of Science, PubMed) from inception to March 2021. The Cochrane guidelines were used to classify the risk of bias.
STUDY SELECTION/RESULTS
A systematic literature search resulted in 290 studies. Thirteen articles met our inclusion criteria and were included in the systematic review. Six articles were identified as good or fair quality and were included in the quantitative analysis. Meta-analysis results indicated that there is no significant difference in retention (RR 1.01, 95% CI:0.96-1.07, P-value 0.66), (RR 1.03, 95% CI: 0.89-1.19, P-value 0.0009) at six and twelve months, respectively. Likewise, for caries prevention there is no significant difference (RR 0.97, 95% CI: 0.91-1.03, P-value 0.19), (RR 0.30, 95% CI: 0.91-1.03, P-value 0.30) at six and twelve months.
CONCLUSIONS
This meta-analysis showed no statistically significant difference between the hydrophilic RBS and alternative treatment options (such as conventional resin or glass ionomer) regarding retention or caries prevention at six- and twelve-month follow-up. Future studies are required to investigate longer-term outcomes.

Meta-Analysis
BACKGROUND
Dental caries (DC) is highly prevalent condition affecting mostly young children. There has been no systematic review done on the prevalence of DC amongst 12-year -olds in Africa. Although some African countries have reported a decrease in DC prevalence, others have shown an increase and it is essential to measure current trends in order to identify strategies and programmes that could assist in reducing DC in Africa. The aim of this systematic review was to determine the prevalence of DC (condition) amongst the permanent dentition of 12-year-old children (population) in Africa (context).
METHODS
A systematic review and meta-analysis was performed. Peer reviewed cross-sectional articles from January 2000 until December 2021 was searched and this included the following databases: Pubmed (Medline); SCOPUS; CINAHL (via EBSCOhost); Academic Search Complete (via EBSCOhost); Dentistry and Oral Sciences Sources (via EBSCOhost); and Science Direct. The search was last updated on the 10th January 2022. Joanna Briggs Institute critical appraisal tools were used to assess risk of bias. Prevalence figures were stratified by Urban/Rural status, country and time using a random-effects model. All studies performed on children 12-year-olds on the African continent were included. The prevalence of DC and the DMFT scores were the primary and secondary outcome measures, respectively. Only articles consisting of 12-year-old children who reside in Africa were included in this study. The systematic review was registered with Prospero CRD42021293666.
RESULTS
18,080 participants were included in this review. A total of thirty studies were included in the review. The pooled effect size of dental caries severity was 1.09 (CI 0.91-1.27) and the overall prevalence was 36% (CI 29.4-41.7%). Eritrea (78%) had the highest prevalence of DC while Zambia had the lowest (11%); Eritrea also had the highest DMFT score (2.5) with Sudan having the lowest score (0.49). Urban cities had the highest DMFT score (1.32, CI 0.97-1.68), compared to rural cities (1.13, CI 0.86-1.4) and there was an increasing trend in DC prevalence over time from 28% (CI 23-34%) in 2000 to 2005 to 57% (CI 43-72%) in studies conducted after 2015. The risk of bias was very low where majority of the studies scored more than 50% in the JBI critical appraisal tool.
CONCLUSIONS
There was a wide discrepancy in the DC prevalence and scores across the different countries, settings (rural versus urban) and there was an increase in the prevalence over time. This review was self-funded.

Meta-Analysis
Periodontal outcomes associated with impacted maxillary central incisor and canine teeth following surgical exposure and orthodontic alignment: a systematic review and meta-analysis.
BACKGROUND
Maxillary incisor and canine teeth are commonly impacted and require multidisciplinary treatment to accommodate them in the dental arch.
OBJECTIVES
To assess the periodontal outcomes of impacted maxillary central incisor and canine teeth, which have been successfully aligned in the arch following surgical exposure and orthodontic traction with fixed appliance therapy.
SEARCH METHODS
Systematic literature searches without restrictions were undertaken in eight databases.
SELECTION CRITERIA
Studies reporting surgical interventions in combination with orthodontic traction with fixed appliance therapy to align impacted maxillary incisors or canines published up to January 2023.
DATA COLLECTION
Duplicate independent study selection, data extraction, and risk of bias assessment.
ANALYSIS
Random-effects meta-analyses of aggregate data.
RESULTS
Twenty-three studies (21 retrospective and 2 prospective) were included in the final analysis. Three studies reported outcomes for maxillary central incisors and 20 reported outcomes for maxillary canines. For maxillary central incisors, all three studies were rated as being at moderate risk of bias. For maxillary canines, 17 studies and 1 study were rated at moderate and high risk of bias, respectively. Both prospective studies were rated at a low risk of bias. Meta-analyses comparing aligned impacted maxillary canines to their non-impacted contralateral counterparts found the former had increased Plaque Index scores (mean difference [MD] 0.19; 95% confidence interval [CI] 0.03, 0.35; P = 0.03), increased clinical attachment loss (MD 0.40 mm; 95% CI 0.17, 0.63; P = 0.01), increased pocket probing depth (MD 0.18 mm; 95% CI 0.07, 0.28; P = 0.001), increased bone loss (MD 0.51 mm; 95% CI 0.31, 0.72; P < 0.001), and reduced keratinized gingival width (MD -0.31 mm; 95% CI -0.61, -0.01; P = 0.04).
CONCLUSIONS
Limited evidence suggests that surgical exposure and orthodontic alignment of impacted maxillary central incisor or canine teeth, results in modest adverse effects in the periodontium. These findings should be viewed with caution as our certainty for these outcomes is very low to low due to the bias and heterogeneity. Further well-conducted studies reporting patient centred outcomes are required.

Meta-Analysis Review
Odontometrics, also known as metric traits, includes mesiodistal, buccolingual dimensions, and crown height. The purpose of this study was to assess pancontinental odontometric variations in the crown dimensions of primary teeth. Ten electronic databases were searched to identify studies that measured crown dimensions of primary teeth, published in English language, without year restriction up to July 2020. Studies included cross-sectional research measuring on casts, subjects, and on radiographs of healthy children. Meta-analysis was performed, and risk of bias was assessed using modified Newcastle-Ottawa Scale. Eighty-seven observational studies were included, with 24,634 participants (9487 males, 11,083 females; 19 studies lacked gender information). Only one study showed a low bias risk, whereas 81 and 5 studies had moderate and high risk, respectively. Sixty-five studies included for meta-analysis revealed heterogeneity in mean mesiodistal dimensions of maxillary first molars from Asia (I -99.7%), buccolingual measurements of mandibular first molars from Europe (I -99.9%), crown height of mandibular second molars from Africa and Europe (I -79.8%). Among mesiodistal and buccolingual dimensions, Australians have larger while Asians have smaller teeth. Pertaining to crown height, very few studies could be found in the literature. This review highlights the variations in crown dimensions of primary teeth among populations.

Journal of Dentistry Dec 2021To evaluate the association and level of evidence between socioeconomic status (SES) and tooth wear (TW) in children, adolescents, and adults. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
To evaluate the association and level of evidence between socioeconomic status (SES) and tooth wear (TW) in children, adolescents, and adults.
DATA
Eligibility criteria comprised population-based observational studies assessing the association between SES and TW in permanent dentition of adolescents and adults. Interventional and descriptive studies or those without an internal comparison between exposed and nonexposed groups were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied where applicable. Risk of bias (RoB) was assessed using the Newcastle-Ottawa scale. Meta-analyses were conducted to estimate the pooled effect measures. Q-statistic, Istatistic, subgroup and sensitivity analyses assessed study heterogeneity.
SOURCES
PubMed/Medline, Embase, Scopus, Web of Science, LILACS, SciELO, Cochrane Library, and Google Scholar databases were searched for articles published in English between 1st January 1980 and 31st March 2021.
RESULTS
Sixty-five studies were included, involving 63,893 participants in over 30 countries. A positive association was found between TW and education (OR=1.25 [0.96; 1.62]), family income (OR=1.18 [0.91; 1.53]), and private school (OR= 1.24 [0.90; 1.72]) among adolescents. Higher educated adults had a lower risk for TW (OR=0.70 [0.52; 0.93]). Most included studies had a moderate RoB. Limitations relating to population representation and assessment methodologies were identified in the included studies.
CONCLUSIONS
SES was associated with TW with its direction depending on the individuals' age. The overall quality of evidence was moderate.
CLINICAL SIGNIFICANC
SES should be included as part of the routine screening and risk assessment for tooth wear.

Meta-Analysis
OBJECTIVES
This systematic review and meta-analysis aimed to evaluate the effectiveness of using maxillary protraction during different stages of the dentition by assessing changes in the jaws and inclination of incisors.
MATERIALS AND METHODS
MEDLINE (PubMed), Embase, Cochrane, Web Of Science, China National Knowledge Infrastructure and Wanfang Databases were searched without time limitations up to 15 January 2022. Google Scholar was used to search grey literature. We included cohort studies that compared the effect of maxillary protraction by analysing primary outcomes and were grouped in age-related conditions. Mean differences and 95% confidence intervals were used for statistical analysis, followed by Grading of Recommendations Assessment, Development and Evaluation analysis.
RESULTS
Six studies were finally included. The heterogeneity test showed P ≥ .1 and I ≤ 50%, and a fixed-effect model was applied. Patients in the early treatment group (ETG) were mainly in the early-mixed dentition stage, while patients in the late treatment group (LTG) were in the late-mixed and early-permanent dentition stage. Meta-analysis showed that there were no statistical differences (P > .05) between the ETG and LTG groups in terms of SNA (the angle composed by point Sella-Nasion-Subspinale), SNB (the angle composed by point Sella-Nasion-Supramentale), ANB (the angle composed by point Subspinale-Nasion-Supramentale), Wits, U1/SN (the angle composed by the axis of upper incisors and Sella-Nasion plane) and L1/MP (the angle composed by the axis of lower incisors and the mandibular plane).
CONCLUSION
Our analysis showed that maxillary protraction applied in the late-mixed or early-permanent dentition stage did not cause different effects on the maxillary growth, the correction of the intermaxillary relationship, the inhibition of mandibular growth and dental tipping of skeletal class III patients when compared to that in the early-mixed dentition stage. Collectively, these data provide a theoretical basis for widening the applicable age period of maxillary protraction and choosing the best treatment opportunity for children patients after a comprehensive assessment.

Review
BACKGROUND
Molar incisor hypomineralization (MIH) is a defect of enamel. The lower strength of the enamel can lead to fractures that predispose for plaque accumulation and caries.
AIM
This systematic review aimed to assess the association between MIH and caries.
DESIGN
Studies involving children of all ages, which reported results on MIH and caries in the permanent dentition, were considered eligible. A search was performed in PubMed and was limited to the period from January 2003 to November 2015, and to studies written in English. Reviews, meta-analyses, and case reports were excluded. The studies were evaluated by use of the Newcastle-Ottawa Quality Assessment Scale (NOS).
RESULTS
Seventeen publications were compiled in the review. Most publications reported that children with MIH have higher caries experience. One study did not observe a difference in DMF values among children affected or not by MIH. Three studies reported that children with MIH were 2.1 to 4.6 times more likely to have caries in the permanent dentition than children without MIH.
CONCLUSIONS
A significant association between MIH and caries was found. The results should, however, be interpreted cautiously due to the lack of high-quality studies. The present systematic review confirms the need for further well-designed studies.

Meta-Analysis
BACKGROUND
Vitamin D plays a crucial role in oral health, and its deficiency is associated to significant changes in oral health diseases. We aimed to explore the relationship between levels of 25-hydroxyvitamin D (25(OH) D) and dental caries in children.
METHODS
Four electronic databases were searched by two investigators including PubMed, Embase, Web of Science, and Cochrane Library. Dental caries results were presented as either prevalence or based on the index of primary and permanent teeth/surfaces with decaying, missing, and filled areas, while vitamin D levels were determined through laboratory testing. Two researchers independently selected studies, collected information, assessed risk of bias, and evaluated the study quality. Any disagreements were resolved through discussion.
RESULTS
A total of 13 studies were included, comprising 5 cross-sectional studies, 5 cohort studies, 3 case-control studies, all of which had high methodological quality. Our meta-analysis showed that children with vitamin D deficiency had a 22% higher risk of dental caries than those with normal vitamin D levels, with a relative risk (RR) of 1.22 and a 95% confidence interval (CI) of 1.18 to 1. 25. Further subgroup analysis according to the three types of studies showed that the risk of dental caries in children with vitamin D deficiency was higher than that in normal vitamin D level group (cohort studies: 62%; cross-sectional studies, 19%; and case-control studies, 5%). Additionally, according to age, subgroup analysis also showed that the risk of dental caries in children with vitamin D deficiency was higher than that in normal vitamin D level group (permanent teeth studies, 28%; deciduous teeth studies, 68%; and mixed dentition studies 8%).
CONCLUSIONS
Levels of 25 (OH) D have been found negatively associated with dental caries in children, indicating that low vitamin D levels may be considered a potential risk factor to this dental disease.

Meta-Analysis Review
Alveolar ridge preservation (ARP) procedures can limit bone changes following tooth extraction. Flapped and flapless surgical approaches have been used for ARP; however, there is a lack of strong scientific evidence regarding their specific influences on the clinical outcomes of ARP. The aim of this systematic review and meta-analysis was to evaluate the effects of flapped and flapless surgical approaches on the dimensional changes of hard and soft tissues and patient-reported outcomes following ARP. Electronic databases were searched to identify randomized controlled trials (RCTs) that compared flapped ARP by means of a coronally advanced flap to flapless ARP where barrier membranes were left exposed. The risk of bias was assessed using the Cochrane Collaboration Risk of Bias tool. Data were analysed using a statistical software program. A total of 754 studies were identified, of which five studies with 149 extraction sockets in 128 participants were included. Overall, meta-analysis did not show any significant differences in the changes in ridge width or height between flapped and flapless ARP. The use of flapless ARP was associated with significantly less postoperative pain, thicker labial soft tissues, and marginally more favourable changes in width of the keratinized tissues compared to the flapped approach. The short-term hard tissue changes following ARP with a flapped or flapless approach are comparable. Postoperative pain and labial soft tissue changes are more favourable following ARP using a flapless approach. Further evidence from long-term RCTs is still required to substantiate the current findings.
