Use of splinting in traumatized primary teeth: A systematic review of case reports

The aim of this study was to explore the use of splinting in the management of traumatized primary dentition in case reports published in the literature. Systematic searches were performed in the main health databases to identify case reports (a) with children presenting trauma in primary teeth, and (b) those that described any outcomes related to the use of splints in the management of traumatized primary teeth. The stages of study selection, data extraction and risk of bias analysis were performed. Descriptive data analysis was described. The reporting of information from this review was based on the PRISMA 2020 guidelines. Of the total number of studies initially found (n=246), eight were case reports. Outcomes of splint immobilization in primary teeth with luxation (intrusion, extrusion, and lateral displacement), intra-alveolar root fracture and/or alveolar fracture were reported. All case reports described splinting as a viable technique for immobilizing traumatized primary teeth, regardless of the type of traumatic dental injury (TDIs) and splinting technique used. Only case report verified the effectiveness of the splinting in the management of dentoalveolar trauma and demonstrated the clinical effectiveness of the contentive approach. Based on low evidence studies with a moderate risk of bias, it was observed that the use of splints for the management of alveolar bone fractures and intrusive root fractures, and in specific cases of teeth with lateral luxation, can bring additional benefits to the dento-alveolar health of traumatized primary teeth.

Possible Risk Factors for Dental Fear and Anxiety in Children Who Suffered Traumatic Dental Injury.

Children who undergo painful experiences such as traumatic dental injury (TDI) during their early years are more likely to be at an increased risk of developing dental fear and anxiety (DFA). The purpose of this study was to identify potential risk factors for DFA of these children. The study participants were 220 parents/caregivers and their children who experienced TDI. Their socio-demographic backgrounds were investigated with the modified WHO Oral Health Questionnaire for Children that included questions about parents' knowledge and attitudes, while the DFA level was determined using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) and the Simplified Oral Hygiene Index (OHI-S Index) was used to assess oral hygiene status. The confirmed risk factors are parental knowledge, female gender, and degree of oral hygiene and pain in the last three months, while age, type of TDI, presence of soft-tissue injury, and number of subjective complaints were not confirmed. The overall model predicted approximately 54% of variance in DFA, R2 = 0.545, F (4.215) = 64.28 p < 0.001. These findings emphasise the importance of addressing pain management, improving oral hygiene, and enhancing parental knowledge to mitigate DFA in children with TDIs.

Random tree algorithm to analyse the relation between type of traumatic dental injuries and its demographic and predisposing factors - A cross-sectional study.

Traumatic dental injuries (TDIs) have become the public dental health problem worldwide in children and adolescents. These injuries are complex and multifactorial in aetiology. This study was done with the aim to analyse the association of 'type of TDI' with its demographic and various predisposing factors in children by an advanced statistical method of machine learning (ML) of artificial intelligence (AI). The present study's data were gathered by conducting the observational cross-sectional study among index age-groups 12 and 15 years children of randomly selected schools of different geographical regions. Structured interviews and dental examinations performed were done to record the variables of TDIs in self-constructed proforma. The gathered data were analysed by employing the random-tree model of machine learning algorithm of IBM SPSS Modeler version-18 software. Molar-relationship (2.5), age (1.75), sex (1.5) and geographical region/area (~1.5) were the most important predictors (factors) for the determination of type of dental injury as shown by the random tree model, whereas clinical factors like overjet (0.75), lip-competence (0.5) and overbite (0.5) showed lesser importance in the determination of type of TDIs. Demographic factors (age, sex and geographical region) and one clinical factor (molar-relation) were found as the stronger factors for determining the type of traumatic dental injury in children.

Analysis of the Prevalence of Types of Traumatic Dental Injuries in Young Children in Lahore.

Aim: To analyze the prevalence of type of dental traumatic injuries in young children in Lahore, Pakistan. Method: A descriptive cross-sectional study was conducted at a Co-Education school named the Ali Public School of Raiwind over a period of one month. The sample of total 280 students were used in this study. The data for all students were collected on type of dental traumatic injuries, age and gender. This data was analyzed using SPSS version 23.0. Results: The most frequent TDI involved is Type-I (58.9%) having age group 11–13 years (63.3%) with males (62%) predominance. The result of that study reveals that Type-I fracture of anterior teeth was most common in males who were more vulnerably subjected to traumatic dental injuries than females. Conclusion: There should be cautionary measures taken to avoid dental traumatic accidents that most frequently occur at home and on the roads. Keywords: Traumatic Dental Injuries, Enamel fracture

Secuelas en dentición permanente por trauma en dentición temporal en pacientes atendidos en el Hospital Base Valdivia, Chile.

Aim: To determine the type and frequency of sequelae in permanent teeth as a result of traumatic dental injuries in primary teeth in pediatric patients attended to at the Hospital Base Valdivia, between 2007 and 2012. Material and Methods: A descriptive study was conducted. The medical records of pediatric patients who were affected by traumatic dental injuries in primary teeth and went to the Sub-department of Dentistry of the Hospital Base Valdivia, Chile, were selected according to inclusion and exclusion criteria. The recorded data was: age of the child at the time of the accident, gender, affected primary tooth, type of traumatic dental injuries, and diagnosis of the permanent successor tooth. Descriptive statistics were performed. A chi-square test was used to establish differences between type of traumatic dental injuries and condition of the permanent tooth. Results: The most frequent diagnosis of traumatic dental injuries in primary dentition was subluxation. The primary tooth with the highest frequency of traumatic dental injuries was the right maxillary central incisor; 58.2% of the permanent successors presented some developmental disturbances. The most frequent sequelae observed in permanent teeth were chronological alterations of the eruption. Conclusion: There is a high frequency of sequelae in permanent dentition as a result of trauma in primary dentition. The most frequent sequel observed was chronological alteration of the eruption. It is fundamental to inform parents about the possible consequences that could arise and emphasize the importance of attending periodic follow up in order to prevent or minimize possible sequelae in permanent teeth.

Conservative approach for managing complicated crown-root fracture in a 4-year-old child: A case with 12-month follow-up

Traumatic dental injuries (TDIs) are of great concern when it comes to a child. Crown-root fracture is the most complicated type as both crown and root are affected by trauma. Complicated crown-root fracture seldom occurs in deciduous dentition. It is a tragic experience and requires immediate attention and quick functional and esthetic repair. Appropriate and early diagnosis leads to successful treatment, for which knowledge on types of TDIs, classification, and management is necessary. Complete restoration of teeth affected with trauma will restore function and esthetics and preserve occlusal harmony. The objective of the present case report is to discuss the appropriate diagnosis and conservative treatment of this unusual and rare case of complicated crown-root fracture in a 4-year-old child using tooth fragment reattachment. This case will focus on the options to restore the uncommon trauma and normalize the function and esthetics of the patient, which will lead to improvement of speech, increase in self-confidence and protection of successors, and describe the treatment and aspects concerning follow-up of the patient.

Prevalence and patterns of traumatic dental injuries in primary teeth: a 3-year retrospective overview study in Vienna

ObjectivesThe aim of this study was to retrospectively identify the prevalence, patterns, and accident types of traumatic dental injuries (TDIs) in children with primary teeth in Vienna, Austria.Material and methodsThe investigation was conducted as a retrospective overview study including all children with TDIs in primary teeth at the University Dental Clinic of Vienna (Austria) between 2014 and 2016. Dental records including age, gender, location of trauma, type of trauma, cause of TDI, and location of traumatic incident were obtained. Furthermore, the time of presentation and the time span between TDI and initial treatment were evaluated.ResultsThe sample comprised TDIs in 243 patients with 403 primary teeth. In a ratio of 1:1.45, boys were significantly more involved than girls. Upper central and lateral incisors were most frequently affected (n = 371, 92.1%). Dislocations were the most common type of injury (n = 298, 74%) with subluxations being the most prevalent form (n = 85, 28.5%). In 23% (n = 92), fractures were observed. The majority of traumatic incidents occurred at home (88.5%).ConclusionThe injury characteristics are comparable to what has previously been reported in other studies in pediatric populations.Clinical relevanceTDIs are a prevalent event in children worldwide and incisors are the most affected teeth in the primary dentition. Thus, dental practitioners should be able to handle these injuries.

Critical appraisal of the information available on traumatic dental injuries found in applications.

Traumatic dental injuries (TDI) are a public health problem and the search for information becomes essential to help in their management. The aim of this study was to search existing TDI applications (Apps) to critically describe the characteristics and main information found in them regarding TDI. Searches were performed in the Play Store (Android) and App Store (iOS), using MeSH terms, synonyms and terms related to dental emergencies and TDI, in English, Spanish and Portuguese. Apps with information on the management of post-TDI emergencies or TDI prevention were included. The type of operating system (Android/iOS), cost (free/paid), target audience (dentist/patient), age of classification (free/>17years old), language, star rating (1★ to 5★), number of downloads and post-download ratings, type of dentition (primary/permanent), reference used for classification according to TDI type and management (International Association for Dental Traumatology/Andreasen/others/not reported), and available content (prevention/emergency management/preservation/illustrations) were evaluated. Among 486 apps, 13 were eligible: 11 for Android and 2 for iOS. Most were free (92.3%), for patients (38.4%) and had a free age classification (90.9%). The main language was English (53.8%), and most of the Apps either had no information on star ratings (46.1%) or received 4★ (23.1%). The number of downloads was not reported (23.1%) or was fewer than 100 (23.1%). Most of the Apps were for permanent teeth (61.5%) and had explanations about dental management for TDI emergencies (92.3%) and multiple TDIs (61.5%). Most Apps addressed the importance of monitoring TDIs (76.9%) and contained illustrative images (76.9%). However, many did not report the TDI classification (46.1%), and 38.5% reported TDI prevention. Information on dental trauma management according to dental injury, inclusion of images, target audience, type of TDI and their prevention varied in the available Apps. However, most were focused on permanent teeth and addressed several TDI in English language only.

Treatment Outcomes of Permanent Immature Teeth with Crown Fracture: A Retrospective Cohort Study

IntroductionCrown fractures are a common type of traumatic dental injury. Various factors may affect the outcome of crown fractures. This study aimed to evaluate the treatment outcomes of immature teeth with a crown fracture. MethodsThis retrospective cohort study included patients who presented to a dental trauma center from 2008–2018 with a history of a crown fracture of immature teeth and at least 6 months of follow-up. Outcomes of primary endodontic or restorative interventions as well as reinterventions were evaluated. Kaplan-Meier curves were used to compare the unadjusted differences in survival time. Logistic and Cox regression analyses were performed to identify potential predictors for complication and survival time, respectively. ResultsThe success rates of the primary interventions for 99 teeth (72 patients) after a median follow-up of 22 months were as follows: cervical pulpotomy (90.4%), partial pulpotomy (85.2%), mineral trioxide aggregate apical barrier (80.0%), root canal treatment (66.6%), and only restoration (47.2%). Teeth that received vital pulp therapy were less prone to complications (adjusted hazard ratio = 0.21; 95% confidence interval, 0.09–0.53; P < .05), whereas those with concomitant luxation injuries were more susceptible to complications (adjusted odds ratio = 2.90; 95% confidence interval, 1.01–8.29; P < .05). ConclusionsCrown fractures had a relatively high favorable prognosis. Vital pulp therapy (partial or cervical pulpotomy) had the highest success rate, whereas cases that received only restoration had the lowest success rate. Teeth with concomitant luxation injuries had more odds and hazards of complications.

STORAGE MEDIUM FOR AVULSED TEETH: A LITERATURE REVIEW

Avulsion injury is one of the most severe types of traumatic dental injuries. Following avulsion, periodontal ligament tissues are injured and the vessels and nerves of the pulp rupture at the apical foramen which causes pulp necrosis. In studies it was reported that the key to retention of the knocked-out teeth was to maintain the viability of the periodontal ligament. Storage media plays an important role in preserving the viability of PDL cells during extra alveolar time. This article highlights the different storage medias available for avulsed teeth, along with their merits and demerits.

Traumatic injuries in primary dentition and their immediate and long-term consequences: a 10-year retrospective study from the State University of Rio de Janeiro, Brazil.

Dental trauma is a highly prevalent problem worldwide. The aim of this study was to describe characteristics of trauma to anterior primary teeth and its sequelae for primary and successor teeth over a 10-year period of assistance at the paediatric dental traumatology clinic in the State University of Rio de Janeiro, Brazil. The data were obtained from the dental records of children assisted from 2006 to 2016. Inclusion criteria were trauma to anterior primary teeth; aged <1 to 9 years at the time of trauma; and at least one follow-up appointment. The data concerning traumatized teeth, child's age, soft tissue injuries, types of traumatic dental injuries and sequelae in both dentitions were collected. Of the 1230 dental records, 483 (39.3%) were eligible, consisting of 815 teeth. The mean age at the time of trauma was 37.4 months (239 males and 244 females). The most important characteristics were: tooth 51 was most affected; falls, at home, on a ceramic floor, were the main cause; gingival laceration, enamel fracture and intrusive luxation were the most frequent types of trauma; premature tooth loss of primary teeth and enamel discoloration in their successor were the most frequent sequelae; and injuries in the periodontal tissue were demonstrated as the highest risk for sequelae in successors (OR, 3.798; p< 0.001). Most traumatic injuries occur in young children, in their home environment. Consequences for the primary teeth were more frequent compared to the permanent successor tooth. Traumatized primary teeth involving periodontal tissue have more chances to result in sequelae to their successor teeth.

Causes of Dental Trauma: Results of Findings Among Patients in a Secondary Oral Healthcare Center, Jos, Nigeria.

Background:Dental trauma is a major type of traumatic dental injury (TDI) and a common presentation in many oral health facilities in Nigeria. Despite the high prevalence of TDIs, causes of dental trauma are yet to be fully investigated among Nigerians.Aim:The aim of this study is to determine the types of dental trauma, aetiology, and the causes of dental trauma as it relates with sociodemographic characteristics among dental patients.Materials and Methods:This was a cross-sectional study among patients attending a secondary oral healthcare facility in the North Central city of Jos between January 2019 and December 2020. The sociodemographic features of the patients include patients’ complaints, clinical and social history, result of simple clinical oral examinations, and diagnoses of dental trauma. The classification of Ellis and Davey (1970) was used to classify dental trauma for this study.Results:One hundred and seventy-six (6.7%) patients presented with dental trauma involving 281 teeth. The mean age was 37.54 ± 2.16 years. The most common cause of dental trauma in 48 (27.3%) patients was bone cracking, followed by falls in 33 (18.8%), road traffic accidents (RTAs) in 26 (14.8%), and bottle opening with teeth in 26 (14.8%). Bone cracking was the major cause of dental trauma in 18 (31.0%) educated and 2 (28.6%) non-educated patients. Among the patients, 118 (67.1%) presented with single traumatized tooth. Permanent anterior teeth 151 (53.74%) were more involved, and class 2 trauma involving enamel and dentinal structure was the most common presentation.Conclusion:Oral health awareness campaign on the damaging effect of bone cracking and use of tooth for opening metal caps of bottled drinks among adult population will reduce the prevalence of dental trauma among many adult Nigerians.

Traumatic Dental Injuries During the COVID-19 Pandemic.

This paper details the characteristics of traumatic dental injuries (TDIs) during the Coronavirus 2019 (COVID-19) pandemic in 2020 at an Urgent Dental Care hub at King's College Hospital Dental Institute, London, UK. For comparisons to be made, the characteristics of TDIs from a similar period in 2019 was also collected. Data was collected retrospectively from clinical records of patients suffering from dental trauma during both periods. An analysis was completed and conclusions drawn. The results suggest that the COVID-19 pandemic influenced the frequency, aetiology and type of TDIs. In order to suitably manage the provision of dental services, consideration must be given to the influence of pandemics on the characteristics of dental emergencies.

Traumatic Dental Injuries, Treatment, and Complications in Children and Adolescents: A Register-Based Study

Objective Traumatic dental injury (TDI) is a common dental concern among children worldwide. We performed a retrospective patient register study among children under 18 years to investigate TDIs with respect to causes, treatment, and complications. Materials and Methods We collected information on TDIs from the original patient records of 407 child patients visiting dental clinic of Lithuanian University of Health Sciences, Kaunas, Lithuania. We analyzed all child patients’ ( n = 407) background, cause, type of TDI, treatment, complications, and time elapsed from injury to visit to the dentist. Statistical Analysis The χ 2 -test, analysis of variance (ANOVA), and Kruskal–Wallis and Mann–Whitney tests served in the statistical analyses. Results A total of 579 TDI cases occurred during 2010 to 2016. Lateral luxation (19.8%) and intrusion (14.8%) occurred more often in the primary than the permanent dentition ( p < 0.05). The most common cause of TDI was falling (56%). Avulsion occurred in approximately 10% of cases. Follow-up (44.5%) and tooth extraction (48.3%) were the most frequent treatments in the primary and splinting (25.3%) in the permanent teeth. Pulp necrosis was the most frequent complication in primary (92%) and permanent (54%) dentition. About 1% of the patients obtained dental care during the first hour after injury. Conclusion The most frequent TDIs included lateral luxation in primary teeth and enamel-dentine fractures in permanent teeth. We observed a delay in patients obtaining emergency dental care.

Pulp canal obliteration after extrusive and lateral luxation in young permanent teeth: A scoping review.

In the literature, no single therapeutic approach is preferred for treating dental pulp responses such as pulp canal obliteration (PCO). Some authors still recommend preventive endodontic treatment, whereas others choose not to intervene, to avoid causing possible iatrogenic complications. This review was conducted to explore, in the current scientific literature, the degree of knowledge concerning the onset and development of PCO and pulp necrosis (PN) following dental trauma (i.e. extrusive luxation and lateral luxation) in children and young adults (6-20 years). The authors also evaluated whether and to what extent the stage of dental root development at the time of traumatic dental injury (TDI) influences these pulp responses, and whether PN can arise in teeth already affected by PCO. MATERIALS AND METHODS The literature search was carried out during the period October 2019 to January 2020, using the following databases: PubMed/MEDLINE, SCOPUS and Web of Science. Articles in English reporting on young patients with PCO or PN in permanent teeth affected by trauma were included. Theresearch, whose questions were summarised according to the PICO method, considered the following aspects: patient age, type of TDI, stage of root development, initial treatment, presence of calcification or necrosis, time to onset of the two outcomes (PCO and PN), and duration of follow-up. The articles found were evaluated by two reviewers; in the event of disagreement regarding the inclusion of an article, a third reviewer was called upon to decide. The initial screening of the databases, using the selected search keywords, yielded a total of 343 articles. After exclusion of duplicates and articles not meeting the inclusion criteria, 11 articles remained. Of these, only four completely met the inclusion criteria. Closer analysis of these four publications revealed that they would not easily yield standardised sets of clinical data that might be homogenised in order to produce clear meta-analytical data. Hence the need to limit the data collected to the following seven items: number and type of injuries, type of initial intervention, duration of follow-up, main pulp responses, number and type of pulp responses. PCO is a physiological pulp response associated with a traumatic event, usually a luxation injury. It is diagnosed on the basis of combined radiographic and clinical-anamnesticdata. Signs of PCO start to appear at around one year after the traumatic event, and its development reaches completion by about five years post-trauma. PN, on the other hand, is clearly apparent within the first year. Endodontic treatment, be it carried out as a preventive measure or following detection of PCO, is inappropriate and can cause serious iatrogenic damage. Treatment is indicated only in cases of definite PN.

Traumatic Dental Injuries Occurred in Primary Teeth and their Sequel Effects on the Developmental Permanent Successors: A Controlled Study

Objective: To examine the types of traumatic dental injuries of the primary teeth (TDI-p) and the long-term sequelae on permanent dentition (LSP) comparing with a control group (CG). In addition, a questionnaire that measures parents' knowledge and awareness was used . Material and Methods: The trauma group (TG) consisted of permanent teeth following TDI-p exposed teeth, while the CG consisted of permanent teeth following unexposed teeth with TDI-p of the same patients. In total, 141 teeth were evaluated in 27 patients. Data concerning such as teeth, when TDI-p occurred, types of treatments and types of LSP were collected. Chi-square test was used for intergroup comparison for gender, type of trauma, LSP, age of trauma and parameters in the parental information questionnaire. Significance level was p<0.05. Results: A statistically significant difference was found in the analysis between TG and CG (p<0.001). The prevalence of LSP due to TDI-p was 29.6% and the prevalence of sequelae in CG was 7.4%. The most common LSP was enamel hypoplasia (14.8%). Parents were aware of the importance of TDI-p, and they had insufficient knowledge about its management . Conclusion: TDI-p can be considered a high-risk factor in the development of LSP. Also, the lack of knowledge in parents should be supported by software-based application systems to be developed.

Prevalence of Traumatic Dental Injury in a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

Traumatic dental injury is an injury inflicted on the dentoalveolar system. It has a physical as well as a psychological impact. Despite this concern, epidemiological data regarding its prevalence is insufficient in the literature of Nepal. Hence, this study's objective was to investigate the prevalence of traumatic dental injuries for the patients visiting Universal College of Medical Sciences, Bhairahawa, Nepal, over five years. A descriptive cross-sectional study was conducted using records from the medical record section for the patients presenting at the dental emergency outpatient department of the Universal College of Medical Sciences, Bhairahawa, Nepal, between April 2014 and April 2019. Ethical approval was taken from the Institutional Review Committee of the Universal College of Medical Sciences. Patient demographic data, type of traumatic dental injuries, and etiologies were evaluated from the record section. Out of 10,080 patients registered during the study period, 793 patients (7.86%) were due to traumatic dental injury, out of which 628 (79.2%) were male, and 165 (20.8%) were female. The most vulnerable age group was 20-29 years (42.4%). Most frequently, injuries occurred in June (16%). Road traffic accidents (57.8 %) were the most common mode, and complicated crown-root fracture (23.3%) was the most common type of traumatic dental injury. The frequency of 7.86% of traumatic dental injury indicates that dental traumatology needs special attention for policy planning and professional training.

Characteristic changes of traumatic dental injuries in a teaching hospital of Wuhan under transmission control measures during the COVID-19 epidemic.

Background/AimsIn December 2019, a novel coronavirus emerged in Wuhan City, and a retrospective analysis is necessary to provide clinicians with the characteristics of traumatic dental injuries (TDIs) during the epidemic. The aim of this study was to evaluate the changes in the characteristics of TDIs under the transmission control measures in Wuhan City utilizing an epidemiologic investigation.Materials and methodIn this retrospective study, epidemiologic information, including the number of patients, gender, age, and TDI parameters such as time since injury to the clinic visit, etiology, tooth location, and the type of injury was extracted from the records of patients in the hospital from two periods: period 1 (between January 23, 2020, and April 7, 2020) and period 2 (between January 23, 2019, and April 7, 2019). The data from the two periods were compared and analyzed.ResultA total of 158 patients were treated for TDIs (120 in 2019 and 38 in 2020). Males were more likely to suffer from TDIs than females with a ratio of 1.5:1, both in 2020 and 2019. Other than that, there were characteristic changes in TDIs during the transmission control measures in the COVID‐19 epidemic, which included the number of patients, age, time since injury to the clinic visit, etiology, tooth location and the type of TDI.ConclusionThe transmission control measures during the COVID‐19 epidemic had a significant impact on the epidemiology and etiology of TDIs in Wuhan City.

Does dental trauma and its consequences influence the professional hiring process? Development, validation and application of an assessment tool

ObjectivesTo develop and validate a questionnaire concerning the aspects evaluated during the hiring process by human resources professionals (HRPs); to apply the validated questionnaire; and to evaluate the perceptions and judgment of HRPs regarding different traumatic dental injuries (TDIs) and their consequences (TDI-Cs). Materials and methodsThe acceptability, discriminative properties, internal consistency and test-retest reliability of the developed questionnaire were evaluated, using the same methodology as the main study and adopting a pilot sample. For both the validation process and the application phase, images of one male and one female were manipulated, or not (control), to create different types of TDI (enamel fracture, enamel and dentin fracture, avulsion) and TDI-Cs (crown discoloration, tooth loss due to avulsion). In the application phase, the images were analyzed by 100 HRPs using the validated questionnaire, and the results were analyzed using the Friedman, Wilcoxon and Mann–Whitney tests (P < 0.05). ResultsThe developed questionnaire produced excellent acceptability, strong discriminative properties, satisfactory internal consistency and excellent to good test-retest reliability. The presence of TDIs and TDI-Cs had a negative effect on the evaluated aspects used during the hiring process (P < 0.001). Tooth loss provoked the worse level of judgment in all evaluated characteristics and in professional hiring. ConclusionsThe developed questionnaire produced valid and reliable responses concerning the aspects evaluated during the hiring process by Brazilian HRPs. TDIs and TDI-Cs had a negative influence on the aspects evaluated during the HRP professional hiring process. Clinical significanceTDIs and TDI-Cs had a negative influence on the aspects evaluated during the HRP professional hiring process.

Prevalence of traumatic dental injuries in India: A systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to estimate the prevalence of traumatic dental injuries (TDI) in India. The secondary objective was to evaluate the prevalence rate according to the differences in gender, age, regions, type of TDI and risk factors associated with TDI. The PubMed, LILACS, Web of Science, Cochrane, CINHAL, and Scopus databases, along with the Public Health Electronic Library, TRoPHI and DoPHER were searched from 1st March to 15thApril 2019 without any restriction of language and year of publication. The qualitative synthesis was done regarding the demographics, study methods, cause of trauma, geographic location, increased overjet and inadequate lip coverage. The meta-analysis was undertaken with STATA-14 software (USA). The pooled prevalence of TDI was calculated using data extracted from 48 studies included in qualitative synthesis and meta-analysis. A sub-group meta-analysis was done by extraction of the data for age groups of 6 years and >6 years. The pooled prevalence of TDI in Indian population was 13 cases in 100 individuals. The prevalence of TDI for age groups of ≤6 was 15% (males, 15%; females, 16%) and for >6 years was 12% (males, 13%; females, 8%). The most common cause of TDI was falls, and most frequent location was home. The odds ratio for occurrence of TDI and inadequate lip-coverage was 3.35 and overjet greater than 3 mm was 3.53. The pooled prevalence of TDI was 13% and slightly higher in children less than 6 years of age. Inadequate lip coverage and increased overjet are the risk factors associated with TDI. Heterogeneity was observed among the studies in terms of design, variables recorded, sampling, study methods and statistical methods. Majority of them also suffered from moderate to high risk of bias.
