Reliability and validity of cross­culturally adapted oral health­related quality­of­Life instruments for Brazilian children and adolescents: a systematic review.

OBJECTIVE: This systematic review aimed to review the reliability and validity of oral health-related quality of life (OHRQoL) questionnaires for Brazilian children and adolescents. Also, the cross-cultural adaptation was evaluated. METHODS: This systematic review is registered in PROSPERO (CRD42022300018) and was performed based on the COSMIN guideline. Electronic searches were performed in the PubMed/MEDLINE, Web of Science, Lilacs, BVS (BIREME), Scielo, and Embase databases until March 2023 by two independent reviewers. There was no restriction on time or language. The following studies were included: validation studies and cross-cultural adaptation of OHRQoL instruments into Brazilian Portuguese; studies that evaluated the measurement properties of OHRQoL questionnaires in children and adolescents and that reported at least one of the measurement properties: reliability, internal consistency, error measurement, content validity, construct validity, criterion validity, discriminant validity, and/or convergent validity. The following were excluded: studies of systematic reviews of OHRQoL measures; studies reporting OHRQoL assessment through instruments; construction (development) and validation of a new instrument; questionnaires that had a single item; and validation for Portuguese from Portugal. The cross-cultural adaptation process and psychometrics of the included studies were verified. RESULTS: 6556 articles were identified, and 19 manuscripts were included. All studies were conducted in Brazil, and the age of the participants ranged from 2 to 15.42 years old. Sixteen articles presented the cross-cultural validation steps. Cronbach's alpha of the revised instruments ranged from 0.59 to 0.86. CONCLUSIONS: It can be concluded that most studies provided information and evidence regarding validity, reliability, translation, and cultural adaptation.

Prevalence of Mandibular Third Molars According to the Pell & Gregory and Winter Classifications.

Aim: This study aimed to evaluate the prevalence of mandibular third molar positions according to the Pell & Gregory and Winter classifications, and to verify the association between the two classification methods. Material and Methods: This cross-sectional study was conducted at dental imaging clinic, from January to March 2019. The inclusion criteria were third molars with complete rhizogenesis and the presence of the mandibular second molar. Patients under 16 years were excluded. Digital orthopantomography (panoramic radiography) radiographs of the mandibular third molars were analyzed and observed according to both Pell & Gregory and the Winter classifications, in addition to verifying if they were impacted. Data were submitted to chi-square test. Results: and StatisticsIn total, 1087 teeth were analyzed, and 1055 teeth were included in the study. The teeth were most commonly found to be in the mesioangulated position (41.8%). Higher frequency was observed for position IIB (26.4%). The prevalence of impacted teeth was 79.6%. There was a statistically significant association between the Winter classification and Pell & Gregory classification (p < 0.001). Conclusion: It was concluded that 79.6% of the mandibular third molars were impacted. The most frequent classification of teeth was position IIB, and the mesioangulated position.

Clinical and radiographic evaluation of the Periodontium with biologic width invasion.

BACKGROUND: The biologic width is defined as the coronal dimension to the alveolar bone that is occupied by healthy gingival tissue. The objective of the present study was to correlate radiographic findings of biologic width invasion with the periodontium status. METHODS: It were included 14 patients with restored teeth with biological width invasion, on the proximal sites, observed clinically and radiographically. 122 proximal sites were evaluated, 61 in the test group (biological width invasion) and 61 in the control group (adequate biological width). Smokers and patients presenting periodontal disease or restorations with contact in eccentric movements, horizontal over-contour or secondary caries were excluded from the sample. The invasion of the biologic width was diagnosed when the distance from the gingival margin of restoration to the bony crest was less than 3 mm. Intrabony defect and bone crest level, as well as, their vertical and horizontal components were radiographically evaluated when present. Plaque index, bleeding on probing, probing depth, gingival recession height, keratinized gingival height and thickness, and clinical attachment level were clinically evaluated. Data were subjected to Spearman's Correlation and Wilcoxon's test. RESULT: The most prevalent tooth with biological width invasion was the first molar. There was a statistically significant correlation between the bone crest (p < 0.001), vertical (p < 0.001) and horizontal (p = 0.001) components. In the test group, there was a statistically significant correlation between bleeding on probing (p < 0.001; r = 0.618) and width of gingival recession (p = 0.030; r = - 0.602) with the intraosseous component; and between keratinized gingival height and bone level (p = 0.037; r = - 0.267). In the control group, there was a correlation between plaque index (p = 0.027; r = - 0.283) with bone level and correlation between keratinized gingival thickness and bone level (p = 0.034; r = - 0.273) and intrabony component (p = 0.042; r = 0.226). CONCLUSION: A statistically significant relationship was found between bleeding on probing and gingival recession in patients who presented intrabony defects due to the invasion of biological width, which may be also related to the thickness of the keratinized gingiva.

Influence of ozonized water on pain, oedema, and trismus during impacted third molar surgery: a randomized, triple blind clinical trial.

BACKGROUND: This study aimed to evaluate the efficacy of ozonized water on pain, oedema and trismus after impacted third molar mandibular surgeries when compared to double distilled water. A randomized triple blind trial was conducted. METHODS: Patients with third molars class II-B of Pell-Gregory were included, and surgical extraction was performed. Irrigation was done with ozonized (group 1) or double distilled water (group 2). The type of irrigation and the side to be operated were randomized. Neither the patients nor the operator or evaluator were aware of the irrigation solution. Pain, oedema and trismus were evaluated at baseline, 24-h, 48-h, 72-h and 7-days after treatment. The data were evaluated by Friedman, Wilcoxon, Mann-Whitney tests, and size effect. RESULTS: It was included 8 men and 12 women, with a mean age of 20.9y.o. The initial pain mean was 7.94 (±12.81) (group 1) and 5.50 (±9.12) (group 2) (p > 0,05). There was a statistically significant reduction of pain, oedema and trismus in intragroup analysis (p < 0.05). There was no statistically significant difference (p > 0.05) when comparing the oedema and trismus between groups. The size effect ranged from small (0.23) to large (1.29). CONCLUSIONS: It was concluded that ozonized water was compatible as irrigation method, not inferior to double distilled water, and had satisfactory effects on management of pain, oedema and trismus after surgical removal of the third molar. TRIAL REGISTRATION: This clinical trial was registered in ClinicalTrials.gov NCT03501225 on April 18, 2018.

Reimplante dentário tardio após armazenamento a seco: preservação da função e estética por uma década / Delayed tooth replantation after dry storage: Preservation of function and aesthetics for a decade

Introdução: atualmente, a determinação de estratégias terapêuticas para melhorar o prognóstico da reimplantação tardia de dentes que foram armazenados inadvertidamente em um ambiente seco é um desafio. Relato de caso: paciente com 22 anos de idade procurou atendimento odontológico três dias após a avulsão do incisivo central superior direito. Mecanicamente, raspou-se cuidadosamente a superfície radicular com cureta periodontal e tratou-se quimicamente com hipoclorito de sódio a 5,25%, seguido de EDTA a 17%. Após tratamento extrabucal e preparação quimomecânica, o canal radicular foi preenchido com pasta de hidróxido de cálcio. O paciente não compareceu a todas as reavaliações. Resultados: após 102 meses, o incisivo superior direito estava clinicamente funcional, mas anquilosado. Havia bolsa periodontal por palatina com 5 mm de profundidade e exsudato purulento. A radiografia revelou reabsorção radicular externa avançada. Após o tratamento periodontal, o canal radicular foi preenchido com hidróxido de cálcio e, posteriormente, obturado com MTA. No acompanhamento após 18 meses, a reabsorção radicular se estabilizou. Experimentalmente, um dente extraído, armazenado em condições idênticas, recebeu tratamento semelhante da superfície radicular. Na microscopia eletrônica de varredura, a superfície radicular mostrou um alto grau de limpeza, com os túbulos dentinários patentes, sugerindo permeabilidade radicular favorável. Conclusões: o tratamento superficial da raiz e o curativo intracanal possibilitaram a preservação do dente avulsionado após reimplante tardio, com função e estética satisfatórias por aproximadamente uma década.

Portanto, destaca-se o importante e constante papel da Atenção Primária na promoção da saúde a indivíduos propensos ao quadro de DRC ao detectar, precocemente, a insuficiência renal e proceder com o encaminhamento correto.(AU)

Comparison of Bite Force with Locking Plates versus Non-Locking Plates in the Treatment of Mandibular Fractures: A Meta-Analysis

Abstract Introduction Mandibular fractures represent a high percentage of all facial fractures, and the bite force is a fundamental parameter to measure the actual mandibular function and, subsequently, the masticatory efficiency and quality of life. Objectives The purpose of the present systematic review was to verify if there is any difference in the bite forces of patients with mandibular fractures fixed by locking or non-locking plates, testing the null hypothesis of no difference in this parameter. Data Synthesis A systematic review of the literature was conducted using four databases (PubMed, Virtual Health Library,Web of Science and Science Direct) without restrictions as to publication date or language. We found 3,039 abstracts, and selected 4 articles for this review. Conclusion The overall results show better performance in bite force for the locking plates when compared with the non-locking plates in the incisor region (mean deviation [MD]: 1.18; 95% confidence interval [95%CI]: 0.13-2.23), right molar region (MD: 4.71; 95%CI: 0.63-8.79) and left molar region (MD: 10.34; 95%CI: 4.55-16.13). Although the results of this study indicated a better bite force result with the locking plates, there is still no sufficient evidence to support this information safely.

Third Molar and Their Relationship with Caries on the Distal Surface of Second Molar: A Meta-analysis.

PURPOSE: The aim of this meta-analysis was to determine which characteristics of mandibular third molars (MTMs) are more often associated with an increase in the prevalence/incidence of caries on the distal surface of mandibular second molars (MSMs). METHODS: Three electronic databases were analyzed: PubMed; OVID and the Virtual Health Library. Observational studies were included, and the risk of bias was assessed using The Newcastle-Ottawa Scale. The Comprehensive Meta-Analysis software program was used for meta-analysis. RESULTS: Fifteen studies were included in this systematic review, and five were included in the meta-analysis. The distal surface of MSMs were more likely to exhibit caries in the following scenarios: when MTMs were found in the A position, rather than the C position (OR: 3.45, 95% CI: 2.28-5.22, p<0.001); when the horizontal position was compared with the vertical (OR: 8.12, 95% CI: 3.75-17.58, p<0.001) and distoangular (OR: 9.75, 95% CI: 3.49 - 27.25, p<0.001) positions; and when the mesioangular position was compared with the vertical (OR: 7.25, 95% CI: 3.48-15.10, p<0.001) and distoangular (OR: 9.54, 95% CI: 3.47 - 26.21, p<0.001) positions. CONCLUSION: The results of this study suggest that the presence of MTMs increases the incidence of caries on the distal surface of MSMs. Furthermore, caries on the distal surface of MSMs is more commonly associated with position A and horizontal and mesioangular mandibular molars.

[Gestational history and prenatal care characteristics of adolescent and adult mothers in a maternity hospital in the interior of Minas Gerais, Brazil]. / História gestacional e características da assistência pré-natal de puérperas adolescentes e adultas em uma maternidade do interior de Minas Gerais, Brasil.

The scope of this research was to analyze the gestational history and prenatal care characteristics of adolescent and adult mothers in a maternity hospital located in a city in Minas Gerais, which is a hospital of reference in the macro-region of health of Jequitinhonha. It involved a descriptive cross-sectional study. A total of 327 mothers were interviewed between May 2013 and March 2014 using a semi-structured questionnaire. With a sample of 255, the number of adult women was predominant. With respect to prenatal care, 324 pregnant women had medical appointments. In terms of the location for prenatal care, 79.2% of adolescents were attended in the public health service, while that percentage was 60.4% among adult women. Regarding the type of birth, 54.7% of mothers had normal delivery and 45% had cesarean section. Among adolescents, there was a higher percentage of normal delivery compared to adult women and this data had a statistically significant relationship with the age of the pregnant women. With respect to gestational age at birth, 85.9% had full-term deliveries, 13.5% had preterm delivery and 0.6% had post-term delivery. It was revealed that adolescent mothers were at a disadvantage compared to the other mothers in terms of both socioeconomic characteristics and prenatal care received.

Laser and Cyanoacrylate for the Treatment of Dentine Hypersensitivity: Survival Analysis and Predictive Factors.

OBJECTIVE: The aim of the present study was to determine how long the effects of laser and cyanoacrylate last when used as treatments for dentine hypersensitivity (DH). In addition, the predictive factors of DH recurrence and the prevalence of DH according to type of tooth were investigated. MATERIALS AND METHODS: Sixty-two patients contributed with 434 sensitive teeth. Two hundred sixteen teeth were randomized to receive laser treatment (wavelength of 795 nm) and 218 received cyanoacrylate treatment. Both treatments were applied three times at intervals of 48 hours. Dentine hypersensitivity was assessed by air stimulus at baseline and 1, 30, 90 and 180 days after treatment by a blinded researcher. Additionally, possible etiologic factors were assessed. The data were analyzed by Kaplan-Meier survival curves and by logistic regression. RESULTS: Both groups had signifi cant reductions in DH. Treatment failure occurred in 276 (63.6%) treated teeth and 158 (36.4%) teeth maintained the result of the treatment until the end of the study (censored teeth). The survival rate at 6 months was 36% for laser treatment, and 36% for cyanoacrylate. There was no signifi cant difference between the survival curves (p = 0.703). Gingival recession and abfraction increased the risk of treatment failure by 2.04 (p = 0.002) and 2.76 (p less than 0.001) times, respectively. CONCLUSIONS: Overall, these two approaches to DH treatment had a survival rate of 36%at 6 months. The most prevalent hypersensitive tooth is the first premolar. Gingival recession and abfraction predict the recurrence of DH irrespective of patient age and sex.

Assim, sua visão sobre a prática executada é necessária como componente de avaliação de qualidade da assistência e reflexão sobre a prática. Objetivo: Compreender a percepção da equipe de enfermagem sobre os cuidados providos em uma unidade de clínica médica de um hospital de referência macrorregional em saúde do interior do estado de Minas Gerais. Material e Métodos: A metodologia utilizada foi o estudo de caso, abordagem qualitativa, com entrevistas semiestruturadas. Foram entrevistados 11 profissionais de enfermagem (Técnicos e Enfermeiros), funcionários a pelo menos um ano no local do estudo. Utilizou-se a Análise de Conteúdo Temático para interpretação dos dados e posterior categorização temática. Resultados: A análise dos dados revelou que aequipe de enfermagem possui um bom relacionamento interpessoal, reconhece a necessidade de capacitação e maior humanização nas ações como requisitos para a melhoria da assistência prestada. Enfatizam o papel e a postura do enfermeiro como norteador na condução do processo de trabalho da equipe. Por outro lado, as entrevistas revelaram que existem dificultadores (recursos humanos e materiais insuficientes, desorganização do processo de trabalho) para que se possa prestar uma assistência satisfatória. Conclusão: A percepção da equipe de enfer-magem sobre os cuidados providos revela potencialidades relacionadas a interdicisplinaridade, autoavaliação positiva e deficiências em relação a capacitações, humanização e processo de trabalho.

Introduction: Among the healthcare services, nursing is considered to fundamental for patient care. Thus, the view of nursing professionals on their practice performance is needed as a component of quality assessment of careand reflection on practice. Objective: To understand the perception of the nursing team about the care provided in a medical clinic unit of a macro-regional referral hospital in the interior of the state of Minas Gerais. Material and Methods: This was a case study, with a qualitative approachusingsemi-structured interviews. Eleven nurses (technicians and nurses) were interviewed, who were employees for at least one year at the study site. Thematic content analysis was used to interpret the data and, later, thematic categorization. Results: The data analysis revealed that the nursing team has a good interpersonal relationship, recognizes the need for training and greater humanization in the actions as requirements for the improvement of care provided. They emphasize the role and the position of the nurse as guiding in the conduction of the work process of the team. On the other hand, the interviews revealed that there are difficulties (insufficient human and material resources, disorganization of the work process) in order to provide satisfactory assistance. Conclusion: The nursing team's perception about the care provided reveals multidisciplinary potentialities, positive self-assessment and deficiencies in relation to training, humanization and work process.

Do TMJ symptoms improve and last across time after treatment with red (660 nm) and infrared (790 nm) low level laser treatment (LLLT)? A survival analysis.

OBJECTIVE: Temporomandibular disorder (TMD) is a variety of clinical problems that originate from the area of the temporomandibular joint (TMJ), masticatory muscles, and surrounding tissues. There are different treatment options; however, there is no evidence that low level laser treatment (LLLT) will last about six months. The aim of this study was to determine the survival rate of treatment with red (660 nm) and infrared (790 nm) laser in cases of TMDs. METHODS: In 19 subjects, one side of the face (half face) was randomly selected to receive intervention, in a total of 116 sensitive points. Pain was measured at baseline and time intervals of 24 h, 30, 90, and 180 days after treatment. Laser irradiation with 4 j/cm² in the TMJs and 8 j/cm² in the muscles was used in three sessions. Kaplan-Meier survival analysis and logistic regression were performed. RESULTS: Both treatments showed statistically significant results (p < 0.001). The survival rate for red and infrared laser was 0.24 and 0.30, respectively, at 180 days. Grinding teeth and headache were associated with recurrent pain. DISCUSSION: Both lasers were effective in the treatment of TMD symptoms and had a low survival rate at 180 days.

Prevalence of bruxism in undergraduate students.

OBJECTIVE: The aim of this study was to determine the prevalence of bruxism in students at the Federal University of the Jequitinhonha and Mucuri Valleys in Brazil. The secondary objectives were to identify the factors associated with bruxism; prevalence of dental wear; and to distinguish the signs and symptoms of temporomandibular dysfunction when present, and verify its relationship with bruxism. METHODS: Two hundred fifty-three students (106 males, 147 females) were clinically examined and answered a questionnaire. Trained researchers performed the dental wear evaluation. The incisal edge and occlusal surface were classified as follows: no wear, wear into enamel, wear into dentin, and extensive wear into dentin. Demographic data and factors related to bruxism were obtained by a questionnaire. The participants who presented dental wear and habit of clenching/grinding teeth were classified as bruxers. The data were analyzed by the SPSS program (p < 0.05). RESULTS: The results showed that 31.6% of the students had bruxism. Of the 7084 teeth evaluated, 376 (5.3%) had some type of facet wear. The teeth that had the highest prevalence of wear facets were the canines. Stress, muscle pain, temporomandibular joint (TMJ) pain, and TMJ noise were significantly associated with bruxism (p < 0.001). CONCLUSION: The prevalence of bruxism was 31.6% in this population. The factors most associated with bruxism were stress, muscle pain, TMJ pain, and TMJ noise.

Management of Cyst-like Periapical Lesions by Orthograde Decompression and Long-term Calcium Hydroxide/Chlorhexidine Intracanal Dressing: A Case Series.

Cyst-like periapical lesions should be treated initially with conservative nonsurgical procedures. In this case series, we describe the clinical and radiographic outcomes of large cyst-like lesions that were treated by orthograde decompression and long-term intracanal use of calcium hydroxide [Ca(OH)2] mixed with 2% chlorhexidine digluconate. Ten cases of cyst-like periapical lesions involving 15 teeth from 10 patients were selected. Maximal radiographic diameters of the lesions ranged from 11 to 28 mm. Nonsurgical procedures were performed, including apical patency, orthograde puncture of cyst-like exudates, chemomechanical preparation, and placement of intracanal Ca(OH)2/CHX dressings, which were periodically replaced during 6-10 months. The root canals were then filled with gutta-percha and sealer. The follow-up periods ranged from 6 to 24 months, and the outcome was classified as healed, healing, or failure. Nine lesions drained copious exudates after canal patency. One lesion only drained bloody serous exudate after periapical overinstrumentation. In 9 patients, intracanal exudation ceased in the first follow-up visit. At the 24-month follow-up, 6 lesions (60.0%) had healed, and 3 lesions (30.0%) were healing, with the corresponding patients being without clinical signs or symptoms. The case of treatment failure was submitted to surgical treatment. Microscopically, the lesion appeared to be an apical cyst with exuberant extraradicular bacterial biofilms attached to the sectioned root apex. This case series supports the use of nonsurgical methods to resolve larger cyst-like periapical lesions.

Effectiveness of Three Desensitizing Dentifrices on Cervical Dentin Hypersensitivity: A Pilot Clinical Trial.

AIM: Cervical dentin hypersensitivity (CDH) is defined as an acute pain of short duration that occurs in dentin exposed to the oral environment. The aim of this study was to evaluate the effi cacy of three desensitizing toothpastes (Sensodyne® Rapid-Relief, Colgate® Sensitive Pro-Relief, Nano P®) for immediate and intermediate-term relief of CDH, when compared with a control toothpaste (Cocoricó®). MATERIALS AND METHODS: Eight patients were enrolled in this clinical study. One hundred thirty-eight hypersensitive teeth were randomized into four groups according to the com- position of the desensitizing toothpaste tested: Group I) strontium acetate and calcium carbonate; II) calcium carbonate and arginine 8%; III) calcium phosphate nanoparticles; and IV) a control toothpaste. A split mouth design was used for one application each of the desensitizing dentifrices. Assessment of CDH was done by evaporative and cold stimuli at baseline, immediately, 24 hours and 30 days after the treatment. RESULTS: The toothpastes presented similar effectiveness and statistically significant improvement in 30 days compared to baseline. Group III showed statistically significant relief for cervical dentin hypersensitivity immediately after the treatment. CONCLUSIONS: The only toothpaste that presented immediate relief effect was the paste containing calcium phosphate nanoparticles in the form of hydroxyapatite.

Biological Restoration of a Fractured Anterior Tooth with the Use of Dentine Pin (Biopins).

This case study describes the esthetic and functional reconstruction of a fractured maxillary central incisor. Due to the requirement for additional retention, treatment was performed using the homogenous technique of biological restoration associated with cementation of posts made from human dentin (biopins). This type of treatment is a new alternative to conventional techniques and favors the dental esthetic and function, as well as biocompatibility, and is an inexpensive procedure.
