RESUMO

AIM: To evaluate the clinical effectiveness of the eruption guidance appliances (EGAs) in treating malocclusion in the early mixed dentition. DESIGN: Electronic databases were comprehensively searched for the eligibility literature of the EGA treatment for a period spanning from the earliest available date in each database up to July 2021. Randomized controlled trials, controlled clinical trials, and prospective and retrospective cohort studies were included in the present review. The quality of clinical trials was assessed according to the Cochrane Collaboration's tools (RoB2.0 and ROBINS-I), whereas cohort studies were based on the Newcastle-Ottawa Scale (NOS). The data were gathered and synthesized with the Stata software (version 12). RESULTS: The screen yielded 436 articles, of which 17 papers were potentially eligible, and 7 articles from 3 studies (1 RCT, 1 CCT, and 1 PCS) were qualified for the final review and analysis. The meta-analysis showed both favorable dentoalveolar and skeletal changes in short term. Both overjet and overbite had a significant decrease after treatment (MD = -2.38 mm, 95% CI: -2.82 to -1.94, p < .001, and MD = -2.43 mm, 95% CI: -3.52 to -1.35, p < .001, respectively), and SNB increased significantly by 0.73 degrees (95% CI: 0.17-1.28, p = .01). After the retention period, however, overbite had a significant increase of 0.88mm, which indicated the occurrence of a relapse (95% CI: 0.60-1.16, p < .001). CONCLUSIONS: According to the existing evidence, the EGA treatment is effectively correcting overjet and overbite in the early mixed dentition in short term; furthermore, high-quality and long-term studies are warranted to determine its long-term effectiveness.

RESUMO

PURPOSE: To analyze the morphology of shapes and positions of the apical foramina in permanent maxillary and mandibular posterior teeth. METHODS: Examination of the apical foramina was performed with a stereomicroscope at a magnification of 10×. The anatomic parameters evaluated were the shapes of the peripheral contours of the apical foramina (rounded, oval, asymmetric, and semilunar). The location of the apical foramen was recorded as a center, buccal, lingual, mesial, and distal surface. RESULTS: Results have shown that the frequency of deviation was 68% in all teeth being assessed, while the most frequent location of the apical foramen was in the center, with 32% followed by distal with 18%. The common shape of apical foramina was round shape in all the teeth. CONCLUSIONS: The variation in the location and shapes of apical foramina in teeth. The commonest deviation in location of apical foramina was distal and the frequent shape was of a round shape.

RESUMO

The emergence of the novel virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease (COVID-19) has led to a global pandemic and one of the most significant challenges to the healthcare profession. Dental practices are focal points for cross-infection, and care must be taken to minimise the risk of infection to, from, or between dental care professionals and patients. The COVID-19 epidemiological and clinical characteristics are still being collated but children's symptoms seem to be milder than those that adults experience. It is unknown whether certain groups, for example children with comorbidities, might be at a higher risk of more severe illness. Emerging data on disease spread in children, affected by COVID-19, have not been presented in detail. The purpose of this article was to report current data on the paediatric population affected with COVID-19 and highlight considerations for dentists providing care for children during this pandemic. All members of the dental team have a professional responsibility to keep themselves informed of current guidance and be vigilant in updating themselves as recommendations are changing so quickly.

RESUMO

OBJECTIVE: The purpose of this study was to perform a comprehensive audit of dental treatment provided to special needs patients (SNP) under general anesthesia (GA) over a ten-year period. STUDY DESIGN: Special needs patients who received dental treatment under GA as an in-patient at Queen Mary Hospital, Hong Kong SAR during the time period January 2002 and December 2011 were included in the study. The study population was divided into three groups, based on age (<6years, 6-12 years, >12 years). One-way ANOVA was used to evaluate the effect of "age group" on duration of treatment, post-recovery time, treatment procedures and utilization of different restorative materials. Kappa statistics were used for intra-examiner reliability. RESULTS: A total of 275 patients (174 males and 101 females) were included in the study. The mean age of the patients at the time they received GA was 12.37±10.18 years. Dental procedures performed were mostly restorative in nature (47%). The >12 years group had significantly shorter treatment duration (p<0.05). No significant difference in post-operative recovery time was observed among the three age groups (p>0.05). The <6 years group received significantly less preventive, but more restorative procedures (p<0.05). Significantly fewer extractions were performed in the 6-12 years group (p<0.05). The use of composite restorations was significantly higher in the <6 years group; while amalgam restorations were more frequently used in the >12 years group (P<0.05). Stainless steel crowns were more frequently employed in SNP under 12 years of age (p<0.05). Intra-examiner reliability was good (k=0.94). CONCLUSIONS: Most of the dental procedures performed under GA on SNP were restorative procedures. For children less than 6 years of age, had longer treatment time under GA. Composite restorations and stainless steel crowns were more frequently used in the primary dentition and amalgam restorations were more frequently employed in the permanent dentition.

RESUMO

OBJECTIVE: The purpose of the study was to evaluate the follow-up pattern of special needs patients (SNP) treated under general anaesthesia (GA) and the failure rates of different treatment procedures and restorative materials. STUDY DESIGN: The treatment records of the patients who received dental treatment under GA during 2005 to 2009 were reviewed. The duration of follow-up periods, the outcomes of different treatment procedures, and the quality of different restorative materials were recorded and evaluated. Statistics were used for the comparison (SPSS 20.0). Pearson's chi-square test and post hoc analysis were used to evaluate the attendance of postoperative appointments and the associations of failure rates of different treatment procedures and restorative materials. Cohen kappa statistics was used for intraexaminer reliability. RESULTS: A total of 177 patients were included in the study. The attendance of postoperative appointments showed a gradual decrease from 96% to 36% within 24 months (P < 0.05). Restorative procedures had the highest failure rates among all treatment procedures (P < 0.05). Stainless steel crowns showed higher survival rates among different restorative materials (P < 0.05). Pulp treatment in primary molars has higher success rate than primary incisors and canines. Composite restorations placed in primary canines have low survival rates. The intraexaminer reliability was good (k = 0.94). CONCLUSION: The attendance for postoperative follow-up appointments declined within two years. Restorative treatment was less successful when compared to preventive and pulp treatments. Stainless steel crowns were more reliable restorations with higher survival rates and composite restorations were less durable.

RESUMO

An observational study was carried out in a teaching hospital in Saudi Arabia to determine the occurrence of dental anomalies among Arabian children. The study included children of Saudi nationality with primary teeth. The study assessed the prevalence of dental anomalies in their primary dentition. The assessment and data collection were conducted by a single examiner, utilizing clinical examination and intra-oral radiographs. A comparative analysis was conducted to examine dental anomalies in relation to gender (boys and girls) and arch type (maxillary and mandibular). In addition, the study explored the occurrence of gender-specific dental anomalies depending on arch type. The data analysis was conducted using IBM Statistics (version 21.0) with a significance level of p < 0.05. In total, there were 245 children included in the final analysis. The study population consisted of boys (66%) and girls (34%), with an average age of 4.87 ± 0.9 years. Taurodontism was the most prevalent dental abnormality, occurring in 2.8% of the individuals in the study sample. The study sample exhibited hypodontia in 2%, supernumerary teeth in 2.4%, double teeth in 2%, and microdontia in 1.2%. Talon cusp and macrodontia have a relatively low incidence of 0.4%. Boys exhibit supernumerary teeth, microdontia, macrodontia, talon cusp, and taurodontism, whereas hypodontia and double teeth were more frequent in girls.

RESUMO

BACKGROUND: Several risk factors contribute to the development of dental caries in children, including sociodemographic, dietary, oral hygiene-related and other miscellaneous factors. Maternal smoking was highly associated with dental caries when compared to smoking by fathers or other household members. OBJECTIVES: The aim of the study was to determine the prevalence of dental caries and their association with exposure to environmental tobacco smoke (ETS) among 5- to 10-year-old students attending private and government schools. MATERIAL AND METHODS: A cross-sectional analytical study was conducted among schoolchildren. Data was collected from the primary caregivers using a pre-tested form to assess the ETS exposure under 5 domains based on history: antenatal exposure; exposure during the index period; exposure in the school neighborhood; exposure in restaurants/roadside stalls; and exposure in bus stops/railway stations. Dental caries was assessed based on the World Health Organization (WHO) guidelines from 1997. The association was reported using prevalence ratios (PRs) (95% confidence interval (CI)). RESULTS: Data was obtained from 211 schoolchildren attending government (39.8%) and private schools (60.2%). The overall prevalence (95% CI) of dental caries was 49.3% (42.5-56.1%). Among all the risk factors evaluated in the study, exposure to ETS was associated with a significantly increased risk of dental caries. The adjusted prevalence ratio (APR) of ETS exposure varied with the mother's educational status and high sugar exposure, although this was statistically insignificant. CONCLUSIONS: The prevalence of dental caries among schoolchildren aged 5 to 10 years in the city was moderate and similar to the national average. Among the risk factors assessed in the study, antenatal exposure to ETS was found to significantly increase the prevalence of dental caries by 41% after adjusting for other factors. Therefore, it is important to educate parents on the causal role of ETS exposure in dental caries.

RESUMO

AIM: To assess the awareness of schoolteachers from Andhra Pradesh towards child abuse and neglect (CAN) through pre- and post-educational intervention (audiovisual aid) questionnaires. MATERIALS AND METHODS: A cross-sectional study was conducted with 300 schoolteachers using a 12-item questionnaire that was created using the standard focus group discussion method. Baseline awareness of CAN was assessed using the questionnaire. Subsequently, all the schoolteachers were educated regarding the various types of CAN and the process of reporting CAN using an audiovisual aid. The same questionnaire was re-administered to all the teachers immediately after the intervention and after three months. The data were statistically analyzed using Fisher's exact test to compare the frequency and distribution of responses among the study participants at various intervals. RESULTS: A statistically significant difference (p value < 0.05) was observed in the awareness of the schoolteachers regarding CAN compared to the baseline and immediately after the intervention. However, there was no statistically significant difference (p value > 0.05) between immediately after the intervention and three months. CONCLUSION: There is a need to have awareness among schoolteachers concerning CAN. However, after education through audiovisual aids, teachers' awareness of CAN has been improved.

RESUMO

AIM: This study aimed to validate the accuracy of dental age (DA) based on the dental development of permanent teeth in children with special needs using Demirjian, Willems, and London Atlas methods and to correlate the dental and chronological age (CA) of children with special needs in Malaysia. MATERIALS AND METHODS: The panoramic radiographic images belonging to children with special needs from the two teaching dental hospitals in Malaysia aged between 5 and 16 years were included in the study. The evaluation was performed by two observers using three methods (London Atlas, Demirjian, and Willems methods) to estimate the accurate DA. The outcome was determined by comparing the mean of the DA and CA. RESULTS: A total of 52 panoramic radiographs were available for the analysis. The London Atlas and Demirjian methods overestimated the DA with a mean of 0.05 and 0.20 years, respectively, while the Willems method underestimated by 0.19 years. The London Atlas method was highly precise and accurate, while Demirjian and Willems methods were the least precise and accurate. CONCLUSION: The London Atlas method of DA estimation is highly accurate and valid for children with special needs in the Malaysian population, followed by the Willems and Demirjian methods.

RESUMO

OBJECTIVE: To evaluate the dental caries status and its association with tooth brushing frequency and previous dental visits among Arabian children. METHODS: Arabian school children attend a specialty pediatric dental clinic at Majmaah University, Saudi Arabia. Only children of Saudi origin with primary dentition were included in the study, and only one examiner was involved in the assessment and data collection. The parents of children completed a questionnaire to investigate possible explanatory variables for caries status, including tooth brushing frequency and previous dental visits. Dental caries were diagnosed according to the criteria recommended by the World Health Organization (2013). The comparison performed was based on sex, age, tooth brushing frequency, and previous dental visits. The descriptive statistics were carried out using SPSS (version 21.0) with a p-value of <0.05 significance. RESULTS: The study involved 268 Saudi children with a mean age of 4.6 ± 1.1 years. The caries prevalence was 78.8%, and the mean dmft was 5.82 ± 4.48, while the overall mean scores for decayed, missing, and filled were 3.903 ± 3.69, 1.18 ± 1.69, and 0.73 ± 1.35, respectively. The mean dmft scores for the <3 years, 3.1-6 years, and >6 years old children were found to be 1.74, 6.58, and 4.58, respectively. Among the children, the females reported higher dmf scores (7.51 ± 4.18) compared to males (4.97 ± 4.39) with a statistically significant difference (p < 0.001). Fifty percent of the children had tooth brushing habits of once daily, followed by never (22.4%), twice daily (15.7%), and rarely (11.2%) brushed their teeth. Statistically significant correlations were found between the children's dental caries status, age, and dental visits, while sex and tooth brushing did not find a correlation. CONCLUSION: The prevalence of dental caries among Arabian preschool children was higher. Mandibular second molars were commonly affected by dental caries, while mandibular central incisors were less frequently affected. The child's age and frequency of dental checkups were positively related to the prevalence of dental caries.

RESUMO

Silver nanoparticles have been a recent focus of many researchers in dentistry, and their potential uses and benefits have drawn attention in dentistry and medicine. The fabrication and utilization of nanoscale substances and structures are at the core of the rapidly developing areas of nanotechnology. They are often used in the dental industry because they prevent bacteria from making nanoparticles, oxides, and biofilms. They also stop the metabolism of bacteria. Silver nanoparticles (AgNPs) are a type of zero-dimensional material with different shapes. Dentistry has to keep up with changing patient needs and new technology. Silver nanoparticles (AgNPs) can be used in dentistry for disinfection and preventing infections in the oral cavity. One of the most interesting metallic nanoparticles used in biomedical applications is silver nanoparticles (AgNPs). The dental field has found promising uses for silver nanoparticles (AgNPs) in the elimination of plaque and tartar, as well as the elimination of bacterial and fungal infections in the mouth. The incorporation of AgNPs into dental materials has been shown to significantly enhance patients' oral health, leading to their widespread use. This review focuses on AgNP synthesis, chemical properties, biocompatibility, uses in various dental fields, and biomaterials used in dentistry. With an emphasis on aspects related to the inclusion of silver nanoparticles, this descriptive review paper also intends to address the recent developments of AgNPs in dentistry.

RESUMO

OBJECTIVES: To perform a comprehensive review of the literature to compare the effects of slow maxillary expansion (SME) and rapid maxillary expansion (RME) on maxillary arch width in patients with bilateral cleft palate. METHODS: The databases include Medline, PubMed, Cochrane (CENTRAL) and (CDSR), OpenGrey, and ClinicalTrials.gov were searched for relevant studies that met the eligibility criteria published before or on 31 October 2022. The search was confined to the English language. The selection of eligible studies and collection of data were performed independently. Risk of bias assessment was conducted using the Cochrane Risk of Bias tool 2.0. RESULTS: Two randomized controlled trials were available based on the search in the published literature. Both studies compared arch width between SME and RME in cleft palate patients and digitals casts and three-dimensional images used for the evaluation. A moderate risk of bias was evident in the available studies. CONCLUSIONS: Both SME and RME can achieve similar amounts of maxillary expansion in patients with bilateral cleft palate.

RESUMO

The objective of this study was to characterize natal and neonatal teeth using micro-computed tomography. A total of 4 natal and 11 neonatal teeth were used for the analysis. The reconstructed scans were assessed for the maximum enamel/dentin thickness and mineral density (MD). The scanned specimens were 3D reconstructed to qualitatively determine the surface topography. The dentin thickness was two-fold greater than enamel thickness for both natal and neonatal teeth (p < 0.05). The cervical third enamel MD remained undetermined in natal and neonatal teeth. The dentin MD at the cervical third for neonatal teeth was significantly lower than the incisal and middle third dentin (p < 0.05). Similarly, the dentin MD at the cervical third of neonatal teeth was significantly lower than the cervical third dentin MD of natal teeth (p < 0.05). Our qualitative analysis suggests that the cervical thirds of both natal and neonatal teeth are peculiar of an anomalous structure, with neonatal teeth showing an irregular outline. Under the conditions of the present study, it can be concluded that the neonatal teeth studied exhibited a distinguishable aberrant structure compared to the natal teeth. Therefore, the natal teeth unfold as a more organized, three-dimensional structure compared to the neonatal teeth.

RESUMO

Most anticancer drugs often fail in clinical trials due to poor solubility, poor bioavailability, lack of targeted delivery and several off-target effects. Polymeric nanoparticles such as poly(lactide), poly(lactic-co-glycolic acid), ALB-loading paclitaxel (Abraxane® ABI-007), lomustine-loaded chitosan, gelatin (decorated with EGF receptor-targeted biotinylated EGF) and so on offer controlled and sustained drug-release properties, biocompatibility and promising anticancer effects. EGF, folic acid, transferrin, sigma and urokinase plasminogen activator receptors-targeting nano preparations improve bioavailability and accumulate drugs on the lung tumor cell surface. However, route of administration, size, pharmacokinetic properties, immune clearance and so on hamper nanomedicines' clinical uses. This review focuses on the benefits, avenues and challenges of nanoparticle-based drug-delivery systems for lung cancer treatment.


Globally, 2 million people are dying annually due to lung cancer and it is the leading cause of death among men in 93 countries. Currently, lung cancer medicine does not reach tumor sites and induces several side effects. Therefore, lung cancer medicines are not effectively reducing lung cancer. One of the efficient ways of delivering anticancer drugs to improve targeted delivery is the conjugation of drugs with cancer cell surface-targeting moieties and encapsulation of unique nanocarriers/nanoparticles. Specific nanoencapsulated drugs selectively target EGF receptors, folic acid receptors, transferrin receptors, sigma receptors and urokinase plasminogen activator receptors on the lung cancer cell surface and deliver the anticancer drugs, leading to cancer regression.

RESUMO

This systematic literature search was performed to determine the clinical effectiveness of vestibular shields (VSs) in children undergoing orthodontic treatment. A comprehensive electronic search was performed in May 2022 using three databases (Medline via PubMed, the Cochrane Central Register of Controlled Trials, and Ovid). The initial screening of articles was based on titles and abstracts. Studies meeting the inclusion criteria were retrieved for the final quality assessment and the methodological qualities were assessed according to the Newcastle-Ottawa Scale and Cochrane risk of bias. The initial search identified 262 publications, of which 15 studies were potentially eligible, with excellent intra-examiner reliability (K = 0.88). A total of five studies were selected for the final analysis, including one randomized controlled trial, three clinical trials, and one cohort study. VS may have potential impacts on orthodontic treatment, lips and dental arches, but further high-quality studies are warranted.

RESUMO

Objective: The objective of this study is to assess the prevalence of gingival recession (GR) and associated etiological factors among school children. Methodology: The study sample consisted of 2095 children from the Nellore region divided into three groups of age ranges from primary dentition (<7 years), mixed dentition (7-12 years), and permanent dentition (>12 years) respectively, attending the department of pediatric and preventive dentistry and the school dental health programs organized by the department. The clinical examination involved measuring GR using William's periodontal probe and evaluating associated etiological factors. Data were statistically analyzed using the Chi-square test. Results: The GR among the study population was 7.9% (n = 165). Among them, males were 46% and females were 54% (P > 0.05). The GR was more in children in the 7-12 years age group (75%), followed by <7 years (21%) and >12 years (4%) age groups. The associated factors include malocclusion (69%), deleterious habits (5%), and anomalies (26%). Anomalies showed an association with GR (P < 0.05) compared to malocclusion and deleteriousness habits (P > 0.05). Conclusion: The prevalence of GR is 7.9%, and GR is more prevalent in males and the 7-12 years age group. GR is associated with transient malocclusion, deleterious habits, and anomalies.

RESUMO

OBJECTIVES: The objectives of the study include the following: (i) to assess the presence of accessory canals and foramina in the body of the mandible using cone-beam computed tomography (CBCT), (ii) to evaluate the location, number, diameter, and length of accessory canals in the body of the mandible, and (iii) to propose a new classification for mandibular accessory canals based on the location. METHODS: A total of 50 (25 males and 25 females) CBCT scans were analyzed in three anatomical planes and three-dimensional (3D) reconstructions for the exact number, location, diameter, and accessory length canals and accessory foramina in the body of the mandible. The statistical analysis used was an independent t-test. RESULTS: Out of 50 CBCT scans, a total of 243 accessory canals and 245 accessory foramina were found. About 53% of accessory canals and foramina were found in males, while 47% were observed in females; 89% were evident in the anterior region, and only 11% were in the posterior region. The majority (64%) of the medial lingual canals had a diameter greater than or equal to 1 mm, while only 32% of accessory canals had a diameter of less than 1 mm (p < 0.05). The mean length of median lingual canals in females was 1.2910 ± 0.2582 mm and 2.6438 ± 0.5288 mm in male subjects. Mandibular accessory canals are classified broadly into anterior and posterior accessory canals, which have further subdivisions. CONCLUSION: CBCT plays a dynamic role in determining the mandible location of various neurovascular structures, including accessory canals and foramina. Female subjects were observed with more accessory canals and foramina and more common in the anterior region than in the posterior region.

RESUMO

COVID-19 affected healthcare professionals globally, especially dentists, which is airborne and transmitted through contact. Most dental procedures are aerosol generated and these aerosols in dental practice tend to transmit acute respiratory infections like COVID-19. Recently, a few authors recommended using the aerosol box to reduce the aerosol count in a dental setting. However, the study aims to describe and recommend a reformed aerosol box desand to practice safe dentistry.

RESUMO

Objectives: This study aimed to determine the mean oxygen saturation values (SpO2) in primary teeth using pulse oximetry. Materials and Methods: This comprehensive literature search on pulse oximeter used for primary teeth in determining pulp vitality using MeSH terms in four electronic databases, including PubMed, Scopus, Cochrane Library, and OvidSP, from January 1990 to January 2022. Studies reported the sample size and the mean SpO2 values (with standard deviations) for each tooth group were included. The quality assessment of all the included studies was done using the Quality Assessment of Diagnostic Accuracy Studies-2 tool and the Newcastle-Ottawa Scale. The meta-analysis included studies reporting means and standard deviations of SpO2 values. The I2 statistics were used to determine the degree of heterogeneity among the studies. Results: A total of 90 studies were identified, of which five met the eligibility criteria that were qualified for the systematic review, and among them, three were included in the meta-analysis. All five included studies were of low quality due to the high risk of bias related to the patient selection, index test, and uncertainties about outcome valuation. In the meta-analysis, the mean fixed-effect measure of oxygen saturation in the pulp of primary teeth was 88.45% (confidence interval: 83.97%-92.93%). Conclusion: Though most of the available studies were of poor quality, the SpO2 in the healthy pulp can be established (minimum saturation, 83.48%) in primary teeth.

RESUMO

This study aimed to identify the association between BMI and dental caries in 6−12-year-old children. This cross-sectional study was carried out among 6−12-year-old school children and their parents. The data on Body Mass Index (BMI) and dental caries for study participants were included in the study. The association between BMI and dental caries was evaluated using SPSS software. The study comprises 400 school children (157 boys and 243 girls) aged an average of 8.9 years. The overall prevalence of dental caries was 84% in primary dentition and 75% in permanent dentition, with a mean DMFT and dmft (decayed, missing and filled teeth) of 2.85 and 5.48, respectively. There was a significant association witnessed between mothers' education and BMI status. A significant association was also evident between decayed (d), missing (m) and filled (f) teeth and overall dmft with different BMI categories (p < 0.05). There was no significant association evident between DMFT and each category of BMI (p > 0.05). The dmft and DMFT within the four BMI categories by one-way ANOVA were highly significant (p < 0.001). Post hoc analysis helped us identify the relationship among the various categories of BMI with dental caries. There was a positive association evident between the BMI of the children and dental caries.
