For this investigation, measurements were taken of the eleven items that comprise the Holdaway soft tissue analysis. Profile differences between ethnicity and corresponding normative values were explored by independent-sample t tests for all facial profile measurements. Student’s t test for independent means was used to determine differences with accepted norms. Significance was set a p 0.000). In contrast, the H angle of the African American females was larger than the normative value. Conclusions: Our study confirms previous research that Myosin 1H contributes to mandibular prognathism. It agrees with the idea that Myosin 1H is less influential in the maxillary soft tissue complex. Understanding the genetic influence of soft tissue growth would allow improved therapies and prevention approaches.","PeriodicalId":323707,"journal":{"name":"Rio de Janeiro Dental Journal (Revista Científica do CRO-RJ)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126911372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study design according to PECOS was: P-Orthodontic patients; E- polymorphism P561T in GHR; C- absence of polymorphism P561T in GHR; O- linear dimension alterations in maxilla and mandibular measurements; S- Cross-sectional studies. The selected studies were qualified by 10-point scoring sheet methodological quality. The subgroups evaluation was performed according to the linear measurements evaluated in two or more studies, as follows: body height, N-S, A’-PTM’, Gn-Go, Pog’-Go, and Co-Go.A fixed effect model was used and the mean differences were performed using the inverse-variance meta-analysis. The I2 (95%) was used to measure statistical heterogeneity between studies, where I2 values of 25%, 50%, and 75% signified low, medium, and high heterogeneity, respectively. Results: The initial search identified 146 studies. After excluding duplicateabstracts, 138 were selected. Seven studies were included in the systematic review. Only one study was classified as having low methodological quality. Three studies were included in the meta-analysis. The meta-analysis demonstrated an association between the Co-Go linear measure and CC genotype (p<0.0001), with a mean difference and confidence interval of 3.79 [2.06, 5.52].

Objective: The aim of this study was to analyze parents’ and caregivers’ knowledge and attitudes toward their children’s toothbrushing habits from 12 to 71 months of age, as well as to verify their knowledge about fluoride and toothpastes’ dispensed amount. Methods: A semi-structured interview script was applied to a convenience sample of parents and caregivers (n = 63) at the Pediatric Dentistry Clinic of a public university. Respondents were asked to simulate the amount of toothpaste used in their children’s brushing. Results were presentedwith absolute and relative frequencies. Results: Regarding their children’s toothbrushing, 49.2% performed oral hygiene of their children; 31.7% mentioned that their children brushed under adult supervision; and 19.1% said their children brushed alone. When asked if they had already received guidance regarding theadequate amount of toothpaste to be dispensed, 54% stated they were never oriented. In 74.6% of cases, the amount dispensed exceeded the recommended dose for preschoolers. In addition, 57.1% reported that the toothpaste is within the reach of the child. Of the respondents, 66.7% pointed out the role of fluoride incaries prevention, and 73% were unaware of its toxicity. Conclusion: In general, parents had good oral hygiene practices with their children. However, most respondents did not use the appropriate amount of toothpaste for their children’s age and were unaware of fluoride toxicity, although they could identify its purpose.","PeriodicalId":323707,"journal":{"name":"Rio de Janeiro Dental Journal (Revista Científica do CRO-RJ)","volume":"35 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121320592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six implants were inserted buccally to the mandibular canal and were restored after at least two months of healing time. The mean follow up period of the implants was 3 years. No implant was lost during this time. All of them remained in excellent clinical condition and met the aesthetic criteria and functional demands of occlusion. Conclusion: The technique presented here proved to be minimally invasive, safe, conservative and effective as an alternative treatment option for dental rehabilitation in mandibular posterior regions with severe bone atrophy.

Objective: To perform a literature review to evaluate the different techniques used to induce hypnosis and the need for its use in dental care, as well as, its results. Sources of data: A bibliographic search was performed in the Google Academic and PubMed databases to identify studies for review. There was no restriction on language or year. Inclusion criteria were studies that addressed the topic of interest. Synthesis of data: Hypnosis aims to improve care by controlling patients’ anxiety, fear and phobias. However, its use is little known by patients and professionals in the context of dental treatment. There are two techniques of hypnosis, namely essential hypnosis and hypnosis by object fixation. The main indications are the need to control the patient’s fear and anxiety during dental treatment and to prepare the patients before performing surgical procedures. It can be used in association with local anesthetics, but this combination is not essential. Conclusion: Hypnosis can be effective at controlling patients’ feelings related to dental care, being the hypnosis by object fixation the most used technique with this purpose. It is considered easy, quick, painless, with low costs and accessible to any dentist who has completed specific training in this field.","PeriodicalId":323707,"journal":{"name":"Rio de Janeiro Dental Journal (Revista Científica do CRO-RJ)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130787287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: To describe the clinical steps for preparation and placement of a direct bonded space maintainer, as well as the follow-up until the eruption of the successor tooth. Case report: Girl, eight years old, presented an adjacent fistula to the primary mandibular right second molar. After clinical and radiographic evaluation, tooth extraction was indicated, due to the impossibility of performing the endodontic treatment. A direct bonded space maintainer was made and installed as an alternative to the band and loop, commonly used in these cases of unilateral loss.

Several studies have proposed a strong genetic background for this condition. Aim: The present cross-sectional study aimed to evaluate whether genetic polymorphisms in the genes that code for estrogen receptors (ESR1 and ESR2) are associated with the presence of isolated TA in a Brazilian sample. Methods: Panoramic radiographs of 142 orthodontic patients were assessed to determine TA of permanent teeth (excluding third molars). DNA of patients was extracted from buccal cells from saliva to evaluate genetic polymorphisms in ESR1 (rs2234693 and rs9340799) and ESR2 (rs1256049 and rs4986938) by genotyping using the real-time PCR technique. For statistical analyses, associations between the distributions of the alleles and genotypes, and the ocurrence of TA were assessed for each genetic polymorphism, with an established alpha of 5%. Results: Thirteen patients had at least 1 congenital missing tooth. The number of congenitally missing teeth ranged from 1 to 11. The genetic polymorphisms rs2234693 and rs9340799 in ESR1 and rs1256049 in ESR2 were not associated with TA (p > 0.05). For the genetic polymorphism rs4986938 in ESR2, the genotype and allele distributions were significantly different between the patients with and without TA (p < 0.05).

Objective: This case report was a rare idiopathic expression that grew in the maxillary sinus. Case report: A 68-year-old black patient, BGS, followed up by the Odontology Service of Cancer Hospital for treating oral lesions (Mucositis) and other conditions resulting from radiation therapy and hormone therapy (Tamoxifen), presented malignant neoplasm at the right breast in 2015; an exostosis biopsy was not performed, since the patient is being treated and followed up by the hospital service. Panoramic radiography and clinical examination were performed. By analyzing the tests, it was possible to notice an image with double radiodensity, more radiopaque in the external portion and less radiopaque in the internal portion, with an aspect of trabecular bone, circumscribed, unilocular, in the region of pedunculated premolar, inside the left maxillary sinus. In order to have a better assessment and diagnostic hypothesis of the case, a CT scan was performed, a tool was applied to measure the density of the profile of the lesion, thus evidencing that the supposed injury invaginates to the interior of the maxillary sinus and had bone density similar to the alveolar crest bone. Conclusion: Simultaneously to other lesions, exostoses are benign lesions, present low aggression and rare symptomatology; exeresis is indicated only when it prevents functioning, or for aesthetics reasons, or when it is not possible to make prostheses. Many cases are incidentally diagnosed from routine radiographic review in medical or dental offices and should be followed up for analysis and verification of their growth.","PeriodicalId":323707,"journal":{"name":"Rio de Janeiro Dental Journal (Revista Científica do CRO-RJ)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115971893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
