Review
Ca-P coatings on Ti implants have demonstrated good osseointegration capability due to their similarity to bone mineral matter. Three databases (PubMed, Embase, and Web of Science) were searched electronically in February 2021 for preclinical studies in unmodified experimental animals, with at least four weeks of follow-up, measuring bone-to-implant contact (BIC). Although 107 studies were found in the initial search, only eight experimental preclinical studies were included. Adverse events were selected by two independent investigators. The risk of bias assessment of the selected studies was evaluated using the Cochrane Collaboration Tool. Finally, a meta-analysis of the results found no statistical significance between implants coated with Ca-P and implants with etched conventional surfaces (difference of means, random effects: 5.40; 99% CI: -5.85, 16.65). With the limitations of the present review, Ca-P-coated Ti surfaces have similar osseointegration performance to conventional etched surfaces. Future well-designed studies with large samples are required to confirm our findings.

Review
(1) Background: Medial sigmoid depression (MSD) of the mandibular ramus is an anatomical variation that resembles non-odontogenic cystic lesion. (2) Aim: The aim of this systematic review was to survey the literature to identify the relevant journal publications, reveal their scientific impact in terms of citations and compare the reported prevalence of MSD. (3) Materials and methods: PubMed, Google Scholar, Scopus and Web of Science were queried to identify relevant publications. The search string was: "medial depression of mandibular ramus" OR "medial depression of the mandibular ramus" OR "medial depression of the mandibular rami" OR "medial depression of mandibular rami" OR "medial sigmoid depression". (4) Results: Eight studies were identified. Dry mandibles and patient dental panoramic radiographs were evaluated in four and seven of the eight studies, respectively. The prevalence of MSD varied from 20.2% to 82.0%. In male and female patients, the prevalence was 18.3-76.0% and 22.0-64.0%, respectively. MSD tended to occur bilaterally and most prevalent in patients with Angle's Class II occlusion. The semilunar and triangular shapes were more common than teardrop and circular shapes. The most cited study had 12 citations. (5) Conclusions: MSD was a seldom investigated and cited anatomical variation that was not uncommon. Its recognition should be further promoted.

AIM
To systematically review the available literature on full mouth rehabilitation of the worn out dentition to help the clinician to choose a suitable philosophy to treat an individual Turner and Missirlian classification.
SETTINGS AND DESIGN
Systematic review following PRISMA guidelines.
MATERIALS AND METHODS
The electronic search engine explored for relevant published studies from the earliest available date, from January 1960 till October 2018. Search terms included were "full mouth rehabilitation OR occlusion OR philosophies of full mouth rehabilitation OR oral rehabilitation OR Pankey Mann Schuyler philosophy OR Hobo Twin stage OR Hobo Twin Table OR worn out dentition OR Turner and Missirlian classification". All collected studies were analyzed and a total of 54 articles and 2 hand searches were extracted, among which 32 articles were selected for the systematic review. Of these 32 articles, 8 were original research studies, 23 case reports and 1 study which comprised 3 case reports were incorporated. Hence, a total of 26 case reports were considered for this systematic review based on CAse REport guidelines.
STATISTICAL ANALYSIS USED
Qualitative analyisis.
RESULTS
Among 26 case reports, 15 cases (57.69%) were treated by Pankey Mann Schuyler philosophy, 2 cases (7.69%) by Hobo twin table and 9 cases (34.61%) by Hobo twin stage philosophy. 21 out of 26 cases were introduced for category no. 1 (80.76%) and 4 cases for category no. 2 (15.38%) and only 1case presented for category no.3 (3.84%) of Turner and Missirlian classification.
CONCLUSION
: No philosophies are universally applicable. Although the most commonly used philosophy is Pankey Mann Schuyler. Hobo Twin stage philosophy is the second most commonly used followed by Hobo Twin table. Maximum patients with worn out dentition are grouped under category no.1 of Turner and Missirlian classification system. Maximum cases of this category are treated by Pankey Mann Schuyler's philosophy.

Meta-Analysis
The nose is the most prominent structure of the face, influencing facial appearance and profile. Orthodontists have an awareness of facial structures, including nasal morphology, when diagnosing and treatment planning. Maxillofacial surgeons influence facial profile by bimaxillary surgery, improving facial aesthetics and harmony. The aim of this review was to summarize the available methods of analysing nasal morphology and profile, and to assess their complexity. A literature search was conducted in PubMed, Scopus, Web of Science, and Embase using the following search terms: "nasal profile analysis", "nasolabial angle", and "nasal profile cephalometric" in order to select studies providing knowledge on correlations between occlusion and nasal development, differences between skeletal classes, ethnic variability, and differences between the sexes. Studies concerning genetic disorders were excluded. Finally, 17 full-text papers were analysed, which pertained to nasolabial angle, or facial profile including the nose. Data concerning methods, ethnic group, reference landmarks used, and measurements made were extracted and placed in tables. Numerous methods of nasal profile analysis can be found in the literature. These methods describe various numbers of parameters, which have influence on facial aesthetic. Nasal parameters are correlated to skeletal class and nasolabial angle, positions of upper incisors, and maxillary inclination.

Review
Titanium (Ti) dental implant failure as a result of infection has been established at 40%, being regarded as one of the most habitual and untreatable problems. Current research is focused on the design of new surfaces that can generate long-lasting, infection-free osseointegration. The purpose of our study was to assess studies on Ti implants coated with different antibacterial surfaces, assessing their osseointegration. The PubMed, Web of Science and Scopus databases were electronically searched for in vivo studies up to December 2020, selecting six studies that met the inclusion criteria. The quality of the selected studies was assessed using the ARRIVE (Animal Research: Reporting of In Vivo Experiments) criteria and Systematic Review Center for Laboratory animal Experimentation's (SYRCLE's) risk of bias tool. Although all the included studies, proved greater osseointegration capacity of the different antibacterial surfaces studied, the methodological quality and experimental models used in some of them make it difficult to draw predictable conclusions. Because of the foregoing, we recommend caution when interpreting the results obtained.

Community Dental Health Aug 2021To determine the association between malocclusion and the severity of dental caries among children and adolescents in the permanent dentition. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To determine the association between malocclusion and the severity of dental caries among children and adolescents in the permanent dentition.
METHOD
A search was conducted in Medline, Cochrane databases, Google scholar, Scopus and Web of Science through October 2020 for studies of malocclusion and dental caries among children and adolescents using the Dental Aesthetic Index (DAI) and the Decayed, Missing, Filled Teeth (DMFT) index. Quality was evaluated using the Newcastle-Ottawa tool for cross-sectional studies. Data were extracted using the Cochrane Collaboration guidelines. Meta-analysis used the Cochrane Program Review Manager Version 5. A random effects model was used to assess the association among different categories of malocclusion with dental caries. GRADE analysis assessed the certainty of evidence.
RESULTS
Five studies met the inclusion criteria. Handicapping malocclusion was significantly associated with higher mean DMFT scores (Mean difference: 1.03, 95% CI, 0.61, 1.44). Participants with severe malocclusion had higher mean DMFT when compared to subjects with normal occlusion (0.32, 95% CI, 0.13, 0.51). Definite malocclusion was also associated with higher mean DMFT scores (Mean difference: 0.19, 95% CI, 0.03, -0.35).
CONCLUSION
Malocclusion is associated with dental caries in the permanent dentition. DMFT scores and the strength of the association increased with severity of malocclusion. Low to moderate certainty of evidence was observed for association between handicapping, severe, and definite malocclusion with dental caries.

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
The main objective of this systematic review was to present the outcomes of the treatment with zygomatic implants (ZIs) in the rehabilitations of atrophic upper jaw.
FINDINGS
An electronic database search in PubMed, along with a manual search, taking into account language and study period, was performed by two observers; any type of clinical trial and series that included the use of ZIs was used. In the search strategy, the following search terms were used: zygom* AND dental (Implant OR implants) AND edentulous NOT (biomechanic* OR finite element) NOT cadaver. The search was limited to English language, full text, and humans. Literature reviews and clinical case reports were not considered. Forty-two articles published between March 2003 and April 2019 were included in this analysis. The cases of 1247 patients were recovered; these patients received 2919 ZIs. Fifty-two ZIs were removed during the follow-up time. The survival rate of these implants was 98.22%, with a minimum follow-up of 1 month and a maximum of 228 months. Different surgical techniques were used to place ZIs; however, the intrasinusal technique was the most used (23 studies). Post-surgical sinusitis was the most common complication reported in the studies (39 cases).
CONCLUSIONS
Based on this review, ZIs were commonly used for rehabilitation of patients with atrophic upper jaw. The survival rates presented were high, and the surgical technique is dependent on the professional experience and the local anatomy. However, it needed additional clinical evidence on bone resorption, esthetic outcomes, and physiological characteristics.

OBJECTIVE
The aim of this systematic review was to evaluate the results of two treatment methods: space opening for an implant and prosthetic replacement (PR) versus orthodontic space closure (SC) for maxillary lateral incisor agenesis (MLIA).
MATERIAL AND METHODS
The protocol of the systematic review is in line with the PRISMA requirements. An electronic search was carried out on July 11, 2021 in Pubmed, ScienceDirect, Web of Science, and Plos One databases. The review included research articles published less than 10 years ago, written in English, involving both PR and SC methods in permanent dentition, and comparing and evaluating them.
RESULTS
A total of 1,061 initially identified articles were found, full texts of 38 articles were read and assessed for eligibility, and 7 of them were included in this review. All of the articles evaluated the esthetics; in addition, 3 of them assessed periodontal health, 1 evaluated temporomandibular joint (TMJ) dysfunction, and 1 evaluated occlusion morphology disorders. One study of 7 found esthetics after SC to be statistically more pleasant, while the others found the results of both techniques to be equally esthetically satisfying. When comparing periodontal status between the groups, one study found gingival recession to be significantly more common in the SC group, while another article revealed that gingival recession and papillary defects were more common in the PR group. The remaining articles stated that there was no TMJ dysfunction, and differences in occlusion morphology disorders were not significant between the groups.
CONCLUSION
The results of MLIA treatment with SC were more favorable esthetically, but the difference was not statistically significant. There is no statistically significant data related to periodontal health, and neither of the treatment methods caused TMJ or occlusion morphology disorders. If both methods are available, space closure is preferable, although high-quality clinical trials are needed to find more evidence.

Review
BACKGROUND
The aim of this systematic review was to analyze the types of human chewing simulator described in scientific literature.
MATERIAL AND METHODS
An electronic search was conducted in the databases PubMed, Embase and Scopus. The search strategy included 10 search terms: ""; "dental materials"; "shear strength"; "fatigue fracture"; "bite force"; "prosthetic materials"; "chewing simulator"; "chewing machine"; "simulated mastication"; and "dental wear simulator." Two researchers worked independently to assess the titles and abstracts of the articles. The quality of the trials selected was evaluated by means of the Consolidated Standards of Reporting Trials scale.
RESULTS
The electronic search identified 80 articles related to the topic of interest. After reading the full texts, ten works were selected. The articles focused mainly on the design of chewing simulators. Most of them were considered of moderate quality. Regarding the characteristics that an ideal chewing simulator should encompass, the devices described in articles varied greatly in terms of movement, periodontal ligament simulation, force sensors, and the materials tested.
CONCLUSIONS
No chewing simulator offers all the characteristics necessary to reproduce human masticatory movements and forces under the humidity and pH conditions of the oral cavity. A simulator that encompasses all these characteristics would make it possible to standardize trials involving simulated mastication. In vitro, dental materials, dental wear simulator.
