Meta-Analysis
UNLABELLED
Dental caries is still one of the most prevalent diseases worldwide. Research has shown that fluoride has a role in caries prevention. For many reasons there are concerns about young children using fluoride-containing oral care products. Consequently, there is a need to identify effective fluoride-free products. A large body of literature now exists on the use of biomimetic hydroxyapatite (HAP) as an active ingredient in oral care products to combat caries.
AIM
To conduct a systematic review of the clinical evidence of the effects of HAP-based fluoride-free oral care products in caries reduction and conduct a meta-analysis of available randomized clinical trials (RCTs).
METHODS
Using the PICO question "In individuals of all ages (P), do fluoride-free oral care products containing HAP as the anti-caries agent (I), compared to products with fluoride or without caries control products (C), reduce the risk of dental caries (O)?" Ovid MEDLINE (PubMed), Scopus, EMBASE, and Web of Science databases were searched using the following keywords: apatite, hydroxyapatite, caries, dental decay, dentin(e), enamel, toothpaste, dentifrice, mouthwash, gels, biofilm, (dental) plaque, ero(de, ded, sion), (de, re)mineral(ise, ized, ised, ization, isation). Reviews, tooth whitening, tooth sensitivity, and in vitro studies were excluded. PRISMA was used for the search and GRADE was used to assess quality. Clinical trials were subjected to the Cochrane Risk of Bias assessment followed by meta-analysis.
RESULTS
291 studies were retrieved; 22 were suitable for systematic review, 5 were clinical caries trials and 4 were RCTs. A meta-analysis of 3 RCTs was possible showing HAP provided 17% protection against caries. The other 17 trials had simpler proxy outcomes for anticaries effects. Some trials showed non-inferior performance of HAP products compared to those with fluoride.
CONCLUSION
There is good evidence that hydroxyapatite in oral care products in the absence of fluoride effectively reduces caries.

Review
Radiesse is a filler composed of calcium hydroxylapatite microspheres suspended in a carboxymethylcellulose gel (CaHA/CMC). It has robust rheological properties that have been associated with its versatility. CaHA/CMC is employed for both on-label indications of filling wrinkles or lines, volumizing, and contouring of areas as well as off-label indications aiming at biostimulation and skin tightening. However, despite the expanding use of CaHA/CMC, overall evidence and recommendations for treatment are currently lacking. This paper aims to provide an up-to-date overview of CaHA/CMC clinical applications, together with a level of evidence of supporting literature, focusing on the face. Based on the data, CaHA/CMC may be considered a safe and effective treatment option for cheeks, jawline, HIV-related facial lipoatrophy, and nasolabial folds. Treatment of marionette lines, chin, pre-jowl, and corner of the mouth also tends to respond with a high degree of efficacy. Despite the recent trend, guidelines, and safety profile of diluted and hyperdiluted Radiesse , no randomized controlled trials have been published.

Review
(1) Background: Nano-hydroxyapatite (nHAp) has been reported to have a remineralizing effect on early carious lesions. The objective of this scoping review was to analyze the remineralization potential of nano-hydroxyapatite (nHAp)-containing dentifrices, by mapping the existing literature. (2) Methods: This review was performed using the PRISMA-ScR Checklist, which is an extension of the PRISMA Checklist for Systematic Reviews and Meta-Analyses. In this study, the population, concept, and context (PCC) framework was used to find relevant papers published between 2010 and 2021. Nano-hydroxyapatite (nHAp) and dentifrices containing nHAp as one of the ingredients were the two main concepts of the research question. MeSH phrases, keywords, and other free terms relevant to nano-hydroxyapatite and dentifrices were used to search the literature databases. (3) Results: Preliminary searches yielded 59 studies; the title and abstract screening results excluded 11 studies. The remaining studies were thoroughly reviewed by two reviewers on the basis of the inclusion and exclusion criteria. Finally, 28 studies were included, and 20 studies were excluded. Most of the studies that were included reported that when nHAp was used alone, it had many different effects, such as remineralization, caries prevention, less demineralization, brighter teeth, less pain, and remineralization of enamel after orthodontic debonding. (4) Conclusions: Dentifrices that contain nHAp offer a variety of therapeutic and preventative effects. Currently, there is insufficient evidence to support the efficacy of nHAp dentifrices in primary teeth. Additional long-term investigations using standardized protocols are required to reach decisive conclusions about the effects of nHAp dentifrices on primary and permanent dentitions.

Nano-hydroxyapatite (nano-HA) is a material with multiple uses due to its biocompatibility and its resemblance to the nonorganic bone structure. It is used in various dental domains such as implantology, surgery, periodontology, esthetics and prevention. The aim of this study is to provide a wide understanding of nano-HA and to promote treatments based on nanomaterials in dentistry. A search in two data bases, Scopus, and PubMED, was conducted over a 5 years period. We chose a 5 years period because this revealed the most recent published studies with the key words 'nano-HA' and 'dentistry'. A number of 32 studies were included in this systematic review. In implantology the main use of nano-HA was as a coating material for titanium implants and its effect was assessed in the matter of osteointegration and inflammatory response as well as antibacterial activity. In tissue engineering the use of nano-HA was directed to surgery and periodontology and this material was assessed mainly as a grafting material. In esthetics and prevention its use was mainly focused on dentinal hypersensitivity treatment, remineralizing potential and as bleaching co-agent. Nano-HA is a relatively novel material with outstanding physical, chemical, mechanical and biological properties that makes it suitable for multiple interventions. It outperformed most of the classic materials used in implantology and surgery but it should be further investigated for bone engineering and caries therapy.

There has been an increasing role in the use of injectable fillers for rejuvenation of the aging face. In this systematic review, we aim to evaluate the existing literature related to soft tissue fillers of the midface. Specifically, we focus on the non-hyaluronic acid fillers including polymethylmethacrylate (PMMA), poly-L-lactic acid (PLLA), calcium hydroxyapatite (CaHA), and autologous fat. A systematic review was conducted in November 2020 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with PubMed and Embase databases. Medical Subject Headings terms used were "cheek" OR "midface" OR "malar" and "filler" OR "poly-L-lactic acid" OR "calcium hydroxyapatite," "autologous fat" OR "polymethylmethacrylate" OR "Artefill" OR "Bellafill" OR "Radiesse" OR "Sculptra." The initial search identified 271 articles. After 145 duplicates were removed, 126 studies were screened for relevance by title and abstract. A total of 114 studies were eliminated based on inclusion and exclusion criteria. Twelve articles underwent full-text review. Seven articles were included in the final analysis consisting of four non-hyaluronic filler products: PMMA, PLLA, CaHA, autologous fat. Most patients were highly satisfied with their results. Due to the gradual volumizing effects of PMMA, PLLA, and CaHA, patient satisfaction generally improved over time. Minor adverse reactions related to treatment included bruising, swelling, and pain. Nodule formation was reported in PLLA and CaHA studies. For autologous fat, 32% of the original injection volume remained at 16 months post-treatment, which still provided clinically improved malar enhancement. Dermal fillers are an attractive treatment option for the aging face due to their high patient satisfaction, long-lasting effects, and low side-effect profile. Patients should be appropriately counseled on the delayed effects of non-HA fillers. Autologous fat is a good option in many patients with the major drawback of unpredictable longevity, which may require a secondary procedure. Future studies should examine the longevity and long-term side effects of these fillers.

Tear trough deformity is a popular target for the treatment with filler injections. The side effects are generally mild and transient. However, delayed complications may occur. We aim to perform a thorough systematic review of the published literature related to delayed complications after tear trough filler injections. A search of published literature was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in June 2021 and included PubMed, ScienceDirect, and Embase databases. The Medical Subject Headings (MeSH) terms used included the following terms: delayed complications, nodules, granulomas, swelling, discoloration, dermal filler, hyaluronic acid (HA), polyacrylamide, calcium hydroxyapatite (CaHA), poly-L-lactic acid (PLLA), eyelid, periorbital, periocular, and tear trough. Twenty-eight articles consisting of 52 individual cases were included in the final analysis. 98% (51/52) of patients were female and had an average age of 48.3 years. HA was the most reported product (71.2%, 37/52), followed by PLLA (4/52, 7.7%), and CaHA (4/52, 7.7%). The most common delayed complication with any dermal filler was swelling (42.3%, 22/52) followed by lumps or nodules (25.0%, 13/52). Xanthelasma-like reaction (17.3%, 9/52), migration (7.7%, 4/52), discoloration (3%, 3/52) also occurred. The average time of onset of any complication was 16.8 months with xanthelasma-like reaction appearing soonest (mean: 10 months) and discoloration appearing latest (mean: 52 months). Most swelling cases were caused by HA. Semi-permanent fillers such as PMMA and synthetic fillers such as PLLA were more likely to be associated with lumps and nodules than other complications. It is important that clinicians who perform tear trough augmentation with dermal fillers have a thorough understanding of the risks of the procedure to diagnose and manage them promptly as well as provide patients with accurate information regarding the potential adverse effects.

Review
Bone defects represent an everyday challenge for clinicians who work in the fields of orthopedic surgery, maxillofacial and oral surgery, otorhinolaryngology, and dental implantology. Various bone substitutes have been developed and utilized, according to the needs of bone reconstructive surgery. Carbonate apatite has gained popularity in recent years, due to its excellent tissue behavior and osteoconductive potential. This systematic review aims to evaluate the role of carbonate apatite in bone reconstructive surgery and tissue engineering, analyze its advantages and limitations, and suggest further directions for research and development. The Web of Science, PubMed, and Scopus electronic databases were searched for relevant review articles, published from January 2014 to 21 July 2023. The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eighteen studies were included in the present review. The biological properties and medical applications of carbonate apatite (COAp) are discussed and evaluated. The majority of articles demonstrated that COAp has excellent biocompatibility, resorbability, and osteoconductivity. Furthermore, it resembles bone tissue and causes minimal immunological reactions. Therefore, it may be successfully utilized in various medical applications, such as bone substitution, scaffolding, implant coating, drug delivery, and tissue engineering.

Archives of Oral Biology Dec 2022This systematic review examines the effect of age on changes to coronal dentin properties. (Review)
Review
OBJECTIVE
This systematic review examines the effect of age on changes to coronal dentin properties.
DESIGN
Pubmed, Cinhal, Scopus, Web of Science and the Cochrane Database were searched for publications up to 31 December 2021. All studies were uploaded and reviewed using Covidence software. At different stages of the review, study selection and the extraction of data were completed by six independent reviewers based on the eligibility criteria. The quality of the articles was judged based on JBI Critical Appraisal Checklist for quasi-experimental studies.
RESULTS
Twelve studies satisfied the eligibility criteria and were included. Dentin characteristics and mechanical properties alter with age, and spatially within a tooth to depend on tubule orientation. Age-related mineral deposition within tubules, and collagen maturation in intertubular dentin compound the spatial effects on mechanical properties. Mechanical properties depend on collagen fiber orientation and apatite alignment relative to dentin tubules, characteristic differences in peritubular and intertubular dentin, and relative dentin tubule distribution within a tooth. The bulk of the research focussed on age-related apatite effects, although many reported limited understanding of changes to collagen, particularly in intertubular dentin.
CONCLUSION
Investigations into the effect of age, depth, site and location on dentin collagen are warranted to minimize tooth loss in older populations by providing targeted adhesive, restorative or preventative interventions.

Review
OBJECTIVE
Bioactive glass and hydroxyapatite are biocompatible materials used as an adjunct to various dental materials. The present study aimed to evaluate the occlusion effects of bioactive glasses and hydroxyapatite on dental tubules.
MATERIALS AND METHODS
We searched the PubMed/Medline, Embase, and Web of Science databases for the relevant records. The methodological quality of the studies was assessed by an accepted quality assessment tool.
RESULTS
From the electronic databases, 372 articles were retrieved. After evaluating the records, 35 in vitro studies were included. The studies revealed a low risk of bias. The primary outcomes from bioactive glass studies demonstrated the potential efficacy of both bioactive glass and hydroxyapatite in dentin tubule occlusion compared to the control.
CONCLUSION
The current systematic review showed that bioactive glass and hydroxyapatite could effectively occlude the dentinal tubules. Thus, desensitizing agents containing bioactive glass and hydroxyapatite can be used to manage dentin hypersensitivity (DH). However, long-term follow-up clinical trials are required in the future before definitive recommendations can be made.
CLINICAL RELEVANCE
This work achieved a satisfactorily systematic review for assessing desensitizing agents containing bioactive glass and hydroxyapatite in dentine hypersensitivity treatments recommended for clinical practice and research.

Review
PURPOSE
The aim of this systematic review was to address the treatment of chondral and osteochondral knee lesions through the use of scaffolds, by showing surgical options and results of this scaffold-based repair approach for the healing of the articular surface.
METHODS
All studies published in English addressing cartilage scaffold-based treatment were identified, including those that fulfilled the following criteria: (1) Levels I to IV evidence addressing the outlined areas of interest, (2) measures of functional or clinical outcome, (3) knee cartilage lesions, and (4) minimum of 2 years of follow-up.
RESULTS
The analysis showed a progressively increasing number of articles per year from 1995 to February 2012. The number of selected articles was 51, with 40 focusing on 2-step procedures and 11 focusing on 1-step procedures. The evaluation of evidence level showed 3 randomized studies, 10 comparative studies, 33 case series, and 5 case reports.
CONCLUSIONS
Regenerative scaffold-based procedures are emerging as a therapeutic option for the treatment of chondral lesions, but well-designed studies are lacking. Systematic long-term evaluation of these techniques and randomized studies are necessary to confirm the potential of this treatment approach, especially compared with the available traditional treatments. Different 1-step scaffold-based strategies are emerging to simplify the procedure and reduce costs.
LEVEL OF EVIDENCE
Level IV, systematic review of Level I to IV studies.
