Prevalence of incisor trauma in persons 6-50 years of age: United States, 1988-1991

Regenerative endodontic treatment and traumatic dental injuries

Pulp necrosis is the most common complication following dental trauma and is often associated with apical periodontitis. The management of these teeth is challenging in terms of large root canals, open apices, thin dentinal walls, and short roots. Over decades the conventional treatment for these teeth was calcium hydroxide apexification, a time-consuming procedure despite high success rates. Subsequently after the introduction of mineral trioxide aggregate and hydraulic calcium silicate materials single visit apical plug procedures became increasingly practiced with comparable success rates to the conventional apexification. The search continued afterward for a clinical procedure that may stimulate further root development and apical closure to avoid the long-term complication of root fracture after apexification. Regenerative procedures using stem cells derived from the apical papilla and blood clots as scaffolds were then introduced for the management of immature teeth, with variable protocols and success rates. This review will cover the evidence available and current position of regenerative endodontic procedures in traumatized immature teeth with apical periodontitis, in terms of clinical protocols, outcome, and potential prognostic factors.

Systematic review of oral health in slums and non-slum urban settings of Low and Middle-Income Countries (LMICs): Disease prevalence, determinants, perception, and practices

BACKGROUND

A comprehensive summary of evidence about oral health in slum settings that could inform policy directions is lacking.

OBJECTIVE

To summarise the latest evidence regarding oral disease burden and their determinants, perceptions, practices, and service utilization in the slums and non-slum urban settings of LMICs.

DESIGN

Systematic review.

DATA SOURCES

Embase and MEDLINE (Ovid); PubMed; Scopus, Web of Science, CRD DARE Database; ELDIS; Essential Health Links; HINARI; African Index Medicus (AIM); and Bioline International, all searched from January 2000 to June 2023 using slum-related terms.

ELIGIBILITY CRITERIA

Empirical studies of all designs were eligible. Studies published in English with full-text available and reporting disease burden, perceptions, behaviours and service utilisation related to oral health of residents of slums or broader settings including slums in low and middle-income countries were included.

DATA EXTRACTION, QUALITY ASSESSMENT, SYNTHESIS AND REPORTING

Studies were categorised and data were extracted and charted according to a preliminary conceptual framework refined by emerging findings. The Mixed Methods Assessment Tool (MMAT) was used to appraise the quality of empirical studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and (where applicable) the Synthesis Without Meta-analysis (SWiM) guideline were adopted for guiding synthesis and reporting. Results were tabulated and narratively summarised.

RESULTS

Full-text articles for 56 records were assessed for eligibility and 23 of the articles were included in this review. The majority (13 studies, 57%) were conducted in Asia, and nine studies (39%) in Africa. Six focused on slums (two examined slum and urban non-slum and four examined purely slum settings), two examined general urban settings, eight included both rural and urban areas in their settings, two examined disadvantaged/low socioeconomic, one assessed rural/urban/metropolis/municipal/district, three covered the national population or whole country, and one looked at high versus low socioeconomic regions. The commonest oral diseases reported were dental caries (prevalence: 13% - 76%), and periodontal diseases (prevalence: 23% - 99%). These were higher in slum settings and showed differences across age groups, gender, and socioeconomic classes. Most participants in the studies perceived their oral health status as satisfactory, a belief commoner among younger people, males, those in higher socio-economic classes, and employed. Mouth cleaning was mostly once daily, usually in the mornings. The use of toothpaste and brush was commonest. Other oral hygiene implements included toothpowder, chewing-stick, neem, charcoal, sand, snuff, salt, and the fingers. There was widespread engagement in home remedies for oral disease cure or prevention, while the use of professional dental care facilities was generally low and problem-driven.

CONCLUSION

The systematic review identified a sparse body of literature on oral health surveys in slums and other urban settings in LMICs. Available data suggest a high oral disease burden, worse in slums, use of inappropriate mouth cleaning tools, self-care practices for pain relief, and few visits to care facilities.

Orofacial Pain

OBJECTIVE

This article explores the multiple etiologies, diagnosis, and management of orofacial pain.

LATEST DEVELOPMENTS

Published in 2019, the International Classification of Orofacial Pain has become the internationally accepted classification system for primary and secondary facial pain. New discoveries in temporomandibular disorders have demonstrated that they are far more complex than the traditional dental mechanistic point of view. A 2020 consensus report released by the National Academies of Sciences, Engineering, and Medicine entitled "Temporomandibular Disorders: Priorities for Research and Care" highlighted this paradigm shift and its importance for patient care, education, and research.

ESSENTIAL POINTS

Orofacial pain comprises many disorders with different etiologies and pathophysiologies. The subjectivity of the pain experience and the interrelated anatomy and physiology of the craniofacial area add to the complexity of diagnosis when the source and etiology of pain are not clear. As orofacial pain straddles the expertise of multiple disciplines, a multidisciplinary approach combining medication, physical therapy, and procedural and psychological strategies is essential in treating patients with orofacial pain.

Impact of dental and orofacial trauma on oral health-related quality of life in adults: A systematic review

PURPOSE

Dental and orofacial trauma among the adult population constitutes a major public health problem. The impact is not just physical but also psychological. To analyse the impacts of dental and orofacial trauma on oral health-related quality of life (OHRQoL) in adults and determine whether the 2 variables are closely interlinked.

METHODS

This is a systematic review. The terms "dental trauma", "orofacial trauma", "oral health", "oral health related impact life", "OHRQoL", "positive and negative affect scale", "quality of life", "facial injuries", "adults", and "young adults" were researched in the databases of PubMed, ScienceDirect, Scopus and Google Scholar for associated studies up to December 30, 2022. A comprehensive search was designed and the articles were independently screened for eligibility by 2 reviewers. The included studies' author, year of publication, the country where the study was conducted, population demographics (number and age), an instrument used for assessing OHRQoL and the relevant result were recorded and compared. The quality of the evidence was assessed using Joanna Briggs Institute checklist for observational studies.

RESULTS

Out of 482 unique records, 3 articles were included for data extraction. Observational studies were included. Two studies did not mention confounding factors. Different scales were used for dental and orofacial trauma and OHRQoL. OHRQoL has a directly proportional relationship with orofacial trauma. Adolescents with orofacial trauma have a significant impact on this value with a prevalence of 88.4%.

CONCLUSION

The highest impact on OHRQoL was seen immediately after the diagnosis of an orofacial trauma. The impact increases with the severity of the trauma. Therefore, to promote overall dental and general health, health education initiatives should include information on the causes, prevention, and requirement for prompt responses by the populace in seeking dental intervention.

Achieving excellence with interdisciplinary approaches in complex orthodontic adult patients

Over the last decades the percentage of adult orthodontic patients has substantially increased. Undeniably, an important motif for seeking orthodontic care at an older age is smile improvement, but this is not all. Frequently, impaired dentofacial aesthetics are combined with several other issues: severe dentoskeletal malocclusions; multiple tooth loss due to caries or endodontic failure; dental agenesis or trauma; periodontal breakdown; or functional problems, such as temporomandibular disorders or obstructive sleep apnoea. Therefore, comprehensive adult treatment mostly requires close collaboration of a team of equally well-trained dental specialists to select and execute the most suitable treatment option for the individual patient from day one. With joint planning, intensive communication with the patient and the involved specialists, and continuous monitoring of the treatment process, true patient-centred care can be delivered. In order to serve the individual patient best, the treating orthodontist does not only need thorough speciality training and continuing education, but furthermore, should be well-equipped with sufficient knowledge of the other dental fields of expertise. In combination with digital technology as an important tool for enhancing communication and efficient exchange of information between all involved team members, excellent joint clinical skills will take comprehensive interdisciplinary treatment to the next level.

Controversies in Dental Traumatology

The management of traumatic dental injuries is more a shade of gray than it is black and white because not all treatment procedures used for dental trauma management are fully evidence based. This chapter has highlighted some of the gray areas related to the treatment and outcome of traumatic dental injuries. Significant controversies in the management of luxation and avulsive injuries have been brought out. Adjunctive treatment such as antibiotic usage, tetanus vaccination, and pain management is also addressed.

Presentation and subsequent care of dental injuries sustained by New Zealand adults

BACKGROUND/AIMS

Injuries to permanent teeth are common and can have lasting effects, but knowledge of their consequences is deficient because there is a lack of information from longitudinal follow-up studies of adult populations. The aim of this study was to use routinely collected adult dental trauma data from New Zealand's no-fault, Government-run social insurance scheme-the Accident Compensation Corporation-to investigate the presentation and subsequent care of dental injuries sustained by adults.

METHODS

Cross-sectional analysis of all new dental injuries recorded during 2008 was followed by prospective analysis of all treatment claimed in the following five years for all new injuries recorded in June 2008 for adults aged 18+ years. Those injuries were categorised into five clinically meaningful, ordinal groups of dental injuries, ranging from least severe (Minor injury) to most severe (Severe displacement). The prospective post-injury treatment information was summarised as (1) restorations; (2) crowns and veneers; (3) completed root canal treatment (preparation and obturation of root canal[s]); (4) extraction (extraction; surgical removal); and (5) implant placement.

RESULTS

Orofacial trauma details were recorded for 32 110 individuals (of all ages) in 2008; males predominated in all age groups, except for those aged 65+ years. Of the 68 890 separate injuries to permanent teeth recorded, 74.9% involved maxillary teeth, with almost 50% involving teeth 21 and 11. Some 66.9% of the dental injuries were classified as Minor; 21.7% involved Fractures or loosening, and 8.2% were Severe fractures. Displacement and Severe displacement injuries comprised 1.8% and 2.5% respectively. During June 2008, dental injuries were recorded for 1325 adults. More than 80% of those dental injuries underwent treatment during the subsequent five years, and more severe initial trauma required more complicated treatment. Minor injuries accounted for 33.5%, fractures/loosening for 50.8%, severe fractures for 1.2%, displacements for 8.8%, and severe displacements for 5.8% of the total cost of treatment provided over that five-year period.

CONCLUSIONS

Although most injuries sustained were minor, their subsequent treatment burden is not only high but also greater with more severe initial trauma. The ongoing societal cost of orofacial trauma appears to be high.

The Global Prevalence and Severity of Dental Caries among Racially Minoritized Children: A Systematic Review and Meta-Analysis

Racially minoritized children often bear a greater burden of dental caries, but the overall magnitude of racial gaps in oral health and their underlying factors are unknown. A systematic review and meta-analysis were conducted to fill these knowledge gaps. We compared racially minoritized (E) children aged 5-11 years (P) with same-age privileged groups (C) to determine the magnitude and correlates of racial inequities in dental caries (O) in observational studies (S). Using the PICOS selection criteria, a targeted search was performed from inception to December 1, 2021, in nine major electronic databases and an online web search for additional grey literature. The primary outcome measures were caries severity, as assessed by mean decayed, missing, and filled teeth (dmft) among children and untreated dental caries prevalence (d > 0%). The meta-analysis used the random-effects model to calculate standardized mean differences (SMD) and 95% confidence intervals (95% CI). Subgroup analysis, tests for heterogeneity (I2, Galbraith plot), leave-one-out sensitivity analysis, cumulative analysis, and publication bias (Egger's test and funnel plots) tests were carried out. The New Castle Ottawa scale was used to assess risk of bias. This review was registered with PROSPERO, CRD42021282771. A total of 75 publications were included in the descriptive analysis. The SMD of dmft score was higher by 2.30 (95% CI: 0.45, 4.15), and the prevalence of untreated dental caries was 23% (95% CI: 16, 31) higher among racially minoritized children, compared to privileged groups. Cumulative analysis showed worsening caries outcomes for racially marginalized children over time and larger inequities in dmft among high-income countries. Our study highlights the high caries burden among minoritized children globally by estimating overall trends and comparing against factors including time, country, and world income. The large magnitude of these inequities, combined with empirical evidence on the oral health impacts of racism and other forms of oppression, reinforce that oral health equity can only be achieved with social and political changes at a global level.

Extraction of a Central Incisor From the Plica Fimbriata in the Outpatient Family Medicine Office: What’s That Rattle?

All-terrain vehicle (ATV) accidents are all too common in the United States and can result in long-term injuries. Therefore, proper after-care is essential for the recovery of an injured person. Here, we present a case where an embedded tooth was overlooked for almost an entire year after an ATV accident. No imaging was performed despite multiple clinic and emergency department visits. The tooth was not discovered to be embedded within the tongue until it later started migrating and protruding. Therefore, extraction was performed in the office.

Epidemiological aspects of dental trauma associated with maxillofacial injures: Ten years of clinical experience in Trieste, Italy

BACKGROUND/AIMS

The prevalence of dental injuries in patients with facial fractures is relevant. Epidemiologically, dental trauma in association with facial fractures generally affects the age group between 20 and 40 years old, with a higher prevalence in males. The aim of this retrospective study was to identify the incidence and etiology of dental trauma associated with facial fractures over a 10-year period.

METHODS

From January 2009 to April 2019, among 381 patients with facial fractures, 353 were included in this study. Age, gender, trauma etiology, injured teeth and dental treatment were investigated.

RESULTS

From 353 patients, with a mean age of 49.7 ± 19.9 years, 247 (70%) were males and 106 (30%) were females. Accidental falls were the most common type of injury (n = 118, 33.4%), followed by road accidents (n = 90, 25.5%), assaults (n = 60, 17%) and sports trauma (n = 37, 10.5%). Fifty-five subjects (15.60%) had dental injuries associated with facial fractures. Of the 145 teeth involved, 48 (33.1%) were diagnosed with luxation, 22 teeth (15.2%) were avulsed, 11 teeth (7.5%) suffered a concussion and there were 10 (6.8%) alveolar wall fractures.Uncomplicated enamel-dentin fracture was the more frequent hard tissue injury (n = 21, 14.5%), followed by complicated crown-root fracture (n = 10, 6.9%), infraction (n = 8, 5.5%), enamel fracture (n = 3, 2%) and complicated enamel-dentin fracture (n = 3, 2%). There was a peak in incidence between 21 and 40 years (42%). Males had a significantly higher risk of facial fractures with dental injury (75%). Maxillary incisors and canines (62.8%) were the most affected teeth.

CONCLUSIONS

There was a high prevalence of dental injuries associated with facial fractures. Maxillary incisors were the most injured teeth, with a higher prevalence in males.

Traumatic dental injuries in adults attending a London-based trauma clinic in the UK: a seven-year survey

Introduction This survey reports the incidence of traumatic dental injuries in an adult population attending an adult dental trauma clinic in a London teaching hospital.Materials and methods Retrospective data were collected from patients attending an adult dental trauma clinic between 2012 and 2018.Results In total, 1,769 patients attended, with more men seen (1,030; 58.2%) compared to women (739; 41.8%) and this was statistically significant (p <0.05). The most common aetiological factor was an accidental fall (728; 41.15%), followed by assaults (413; 23.35%), bicycle accidents (253; 14.3%), sports injuries (132; 7.46%) and road traffic accidents (84; 4.75%). Lateral luxation (833) was the most common traumatic injury and this was followed by avulsions (362; 17%). Enamel-dentine fractures were the most common type of fracture injury (1,273; 64%).Discussion This retrospective survey attempts to report on the incidence of traumatic dental injuries in a London-based cohort of patients attending a specialised dental trauma clinic. In line with other reports, there were more men than women affected, which is probably attributed to behavioural activities.Conclusion(s) Accidental falls are the most common cause of a traumatic dental injury, lateral luxation was the most common type of displacement injury and enamel-dentine fractures were the most common type of fracture injury.

Prevalence and determinants of oral health conditions and treatment needs among slum and non-slum urban residents: Evidence from Nigeria

Oral diseases constitute a neglected epidemic in Low and Middle-Income Countries (LMICs). An understanding of its distribution and severity in different settings can aid the planning of preventive and therapeutic services. This study assessed the oral health conditions, risk factors, and treatment needs among adult residents in the slum and compared findings with non-slum urban residents in Ibadan, Nigeria. The Multistage sampling was used to select adult (≥18-years) residents from a slum and a non-slum urban sites. Information sought from participants included dietary habits, oral hygiene practices, and the use of dental services. Oral examinations were performed in line with WHO guidelines. Associations were examined using logistic regression. Mediation analysis was undertaken using generalized structural equation modeling. The sample comprised 678 slum and 679 non-slum residents. Median age in slum vs non-slum was 45 (IQR:32-50) versus 38 (IQR:29-50) years. Male: female ratio was 1:2 in both sites. Prevalence of oral diseases (slum vs non-slum sites): dental caries (27% vs 23%), gingival bleeding (75% vs 53%) and periodontal pocket (23% vs 16%). The odds of having dental caries were 21% higher for the slum dwellers compared to non-slum residents (OR = 1.21, 95% CI:0.94 to 1.56); and 50% higher for periodontal pocket (OR = 1.50, 95%CI: 1.13 to 1.98), after adjusting for age and sex. There was little evidence that tooth cleaning frequency mediated the relationship between place of residence and caries (OR = 0.95, 95%CI: 0.87 to 1.03 [indirect effect], 38% mediated) or periodontal pocket (OR = 0.95, 95%CI: 0.86 to 1.04, 15% mediated). Thirty-five percent and 27% of residents in the slum and non-slum sites respectively required the "prompt and urgent" levels of treatment need. Oral diseases prevalence in both settings are high and the prevalence was generally higher in the slum with correspondingly higher levels of prompt and urgent treatment needs. Participants may benefit from targeted therapeutic and health promotion intervention services.

Pattern of Traumatic Dental Injuries Among Adults

Background

The etiology, presentation and management of traumatic dental injuries (TDIs) vary significantly between the adult and the younger population. Most epidemiological studies on TDIs have focused on the pediatric age group. This study aims to report and compare the distributions of TDIs among adults in a sub-population in India.

Methods

This prospective observational study was performed on 1562 consecutively selected patients (1218 males and 344 females) from a university dental hospital in India, between July 2014 and June 2018. The clinical examinations were performed by a single trained and calibrated endodontist. Only TDIs to anterior teeth were recorded (canine to canine in the maxilla and mandible) and classified using a modified version of the World Health Organization's (WHO’s) classification. Periapical and panoramic radiographs were taken for all the subjects.

Results

A total of 1562 patients aged between 20 and 73 years, with a mean age of 36 years, were examined during the study period. The total number of teeth with TDIs was 3044. Males (78%) clearly outnumbered the females (22%) in all the age groups. The most common type of injury occurring in both the genders is uncomplicated crown fractures (male=31.0% and female=36.6%). Avulsion injuries are more likely to be seen by a dentist within 1 hour post-trauma. About two-third of the TDIs were caused by road traffic accidents (RTAs) followed by falls in about 20% of the patients.

Conclusion

Uncomplicated crown fracture was the most commonly observed type of TDI, and RTAs were the primary cause of TDI.

Effect of a sports mouthguard on the functional range of motion of the spine and the upper body posture in taekwondo

Background

The aim is to investigate to what extent the different oral protections compared to the habitual occlusion affect the upper body posture in statics and during taekwondo-specific movement.

Methods

12 Taekwondoka (5 f/7 m) of German national team were measured by using a 3d back scanner and an ultrasonic distance measuring (upright stand, taekwondo attack and defense movement, two taekwondo specific combinations) in habitual occlusion, with a custom-made and ready-made mouth protection

Results

There are no significant changes in the upper body posture (p ≥ 0.05). Depending on the dynamic measurements, different significant reactions of the spinal position were found while wearing the custom made mouthguard or the ready-made mouthguard according to the conducted movement.

Conclusion

The measured changes in dynamic movements are not clinical relevant. Based on the positive responses from the participants, the custom-made mouth protection can be recommended combined with an individual analysis.

Permanent tooth avulsion in children and adults: Therapeutic options for longer survival

Introduction: Permanent tooth avulsions (traumatic extraction; total luxation) are one ofthe most severe permanent tooth injuries and can occur as single injuries or associated with other dental injuries or injuries to the face and jaws region. They are defined as the luxation of teeth from the alveoli with complete rupture of periodontal fibres, or with one part attached to the rootcementum and the other to the alveolar bone, thus compromising the dental pulp, root cementum,and alveolar bone. The high prevalence and numerous negative consequences on the stomatognathic systems they have suggest permanent tooth avulsions should be regarded as an important public health problem. The aim: is to point out the therapeutic possibilities of permanent tooth avulsion that can ensure their longer survival in the oral cavity. Conclusion: The treatment strategy for avulsed permanent teeth is always based on limiting root canal infection and periradicular inflammation, shifting the balance from unfavourable (replacement resorption) to favourable (periodontal) healing. The success of therapy and periodontal healing depend on the duration and conditions of extraoral tooth preservation, the degree of damage to the periodontal ligament, and the condition of the pulp.

Large overjet as a risk factor of traumatic dental injuries: a prospective longitudinal study

Purpose

The aim of this longitudinal prospective study was to evaluate if schoolchildren with large overjet experience a greater risk of traumatic dental injuries (TDI) compared to children with normal or small overjet.

Methods

A sample of children aged 6‑13 years was prospectively evaluated after 1 year: from the initial sample, data concerning trauma cases of 1413 children were collected to determine the number and types of injuries, the influence of overjet on the risk of TDI, and the relationships between trauma, age, and gender.

Results

The observed prevalence of trauma was higher for boys, with the largest frequency between the ages of 8 to 12 years: 67.9% of all injuries were hard tissue injuries and 32.1% subluxation and luxation injuries. Children with an overjet of 6 mm or more showed a statistically increased risk of getting trauma [RR = 3.37 with CI (1.81; 6.27)].

Conclusion

In this prospective study, overjet stood out among variables as the most significant risk factor of TDI: an increased overjet of 6 mm or more had a major impact on the risk of trauma, which would speak in favor of early orthodontic correction of an increased overjet to reduce the prevalence of dental trauma

Knowledge of Iranian Parents of Elementary School Children about Traumatic Dental Injuries and its Management

Statement of the Probelm:

Traumatic dental injuries (TDIs) are frequent events during childhood, and emergency management of these injuries has positive outcomes.

Purpose:

The aim of this study was to evaluate the knowledge of parents of school-aged children about dental trauma and to identify the effect of demographic variables such as age, gender, and education on their responses.

Materials and Method:

300 parents of elementary school children were selected through cluster sampling from July 2012 to January 2013 in Yazd, Iran. A questionnaire was designed to collect the data on parents’ knowledge about emergency management of dental trauma, and their demographic characteristics and previous experiences. Statistical analysis of data was performed by SPSS software version 11 using T-test and ANOVA. P-values less than 0.05 were considered significant.

Results:

296 out of 300 participants returned their questionnaires (mean age 33.8± QUOTE ± 5). The parents’ knowledge about TDI managements was inadequate (average score = 7.03). According to T-test and ANOVA statistical tests, there was no significant relationship between knowledge and age (p= 0.155), gender of parents (p= 0.113), gender of children (p= 0.776), occupation (p= 0.112), and the information source (p= 0.160). The relationship between parents’ knowledge and parental educational level was statistically significant (p= 0.010), and least significant difference (LSD) test showed that knowledge score of parents with Bachelor’s degree or higher educational levels (7.83±4) was significantly more than other parents who were not educated (6.97±4), or had high school diploma (6.70±4).

Conclusion:

Majority of parents had little knowledge about TDI and emergency management of avulsed permanent teeth in children. Therefore, it seems that educational programs are necessary to improve parents’ knowledge.

Dental Trauma

Dental trauma and injuries to the dentition are difficult to treat because the treatment goals serve to restore esthetics and function. The oral and maxillofacial surgeon is often called on to coordinate the efforts of rehabilitation after a dentoalveolar injury. A comprehensive understanding of the ideal treatments and use of endodontic, orthodontic, periodontal, and pediatric dental colleagues leads to the best possible results with regards to a restoration of form and function. This article provides a succinct review of the oral and maxillofacial surgeon's treatment in dentoalveolar trauma. Epidemiology, treatment, and preventative measures are discussed in this article.

Prevalence and Occlusal Risk Factors for Fractured Incisors among 11-12-Year-Old Children in the Trinidad and Tobago Population

This cross-sectional survey was carried out to ascertain the prevalence of fractured incisors in 11-12-year-olds. In addition we explored the relationship with overjet, incompetent lips, incisor inclination and to determine if there was any association with ethnicity and gender. All permanent incisors were examined in 672 children comprising 356 females (53.1%) and 315 males (46.9%). The sample comprised 11-12-year-olds in high schools across Trinidad and Tobago. Statistical analysis was undertaken using Chi-square test, independent t-test, and binary logistic regression. The prevalence of fractured incisors was 18.9%. Boys presented with an increased incidence of fractured incisors than girls. 86.3% of dental trauma was untreated. The average overjet of subjects with fractured incisors was 4.2 mm. 18.62% of subjects with fractured incisors had incompetent lips. The most common malocclusion (18.81%) with fractured incisors was class 2 division 1. The Afro-Trinidadian ethnicity had the highest prevalence of fractured incisors (11.0%) when compared to mixed ethnicities, which was statistically significant. Maxillary central incisors were the most commonly injured teeth. Most patients delayed in seeking dental treatment for fractured incisors in our population. Early orthodontic treatment is recommended to help reduce the risk of dental trauma.

Traumatic dental injuries among New Zealanders: Findings from a national oral health survey

BACKGROUND/AIM

Little is known about adult dental trauma experience at the population level. The aim of this study was to estimate the prevalence and associations of dental injuries in New Zealand (NZ) adults.

MATERIALS AND METHOD

Information about dental and orofacial trauma in a representative sample of NZ adults (aged 18-94) was collected in a national oral health survey. As well as self-reported information, the maxillary six anterior teeth were examined for signs of dental trauma. Survey weights were used.

RESULTS

Of the 40.9% (95% CI: 37.6, 44.2) who reported previous orofacial trauma, 69.1% (95% CI: 64.3, 73.5), or just over one-quarter of the sample, reported that this included a dental injury. More males than females had experienced orofacial trauma (51.3% [95% CI: 45.8, 56.8] and 31.4% [95% CI: 27.9, 35.1], respectively). The most common injury was a "chipped or broken tooth" (66.6%, 95% CI: 60.6, 72.1). Almost three-quarters had sought treatment. Clinical examination revealed an overall trauma prevalence of 23.4% (95% CI: 21.0, 26.0) with more males than females affected. Some 14.9% (95% CI: 12.8, 17.2) had one injured tooth, while 6.5% (95% CI: 5.2, 8.1) had two injured teeth. The maxillary central incisors were the most frequently affected. Most participants with clinical signs of trauma had only one of the six maxillary teeth affected. The most common clinical dental trauma observation was evidence of "treatment" or an "untreated enamel fracture", and these were more common among males and those aged 35-44 years.

CONCLUSION

Traumatic dental injuries constitute an important public health issue. More emphasis on preventing them in the NZ adult population is warranted, and public awareness of State-funded cover for dental injuries may need to be bolstered to enable equitable access for injury care. Overall, a greater emphasis on prevention and the importance of initial care for dental injuries could reduce the individual and societal burden.

Traumatic dental injuries in preschool-age children: Prevalence and risk factors

This study examined the prevalence, socio-demographic correlates, and clinical predictors of traumatic dental injuries (TDIs) in the primary dentition among a community-based sample of preschool-age children. The sample comprised 1,546 preschool-age children (mean age 49 [range: 24-71] months) in North Carolina public preschools, enrolled in a population-based investigation among young children and their parents in North Carolina. Information on socio-demographic, extraoral, and intraoral characteristics was collected and analyzed with bivariate and multivariate methods, including logistic regression modeling and marginal effects estimation. The prevalence of dental trauma was 47% and 8% of TDI cases were "severe" (pulp exposure, tooth displacement, discolored or necrotic tooth, or tooth loss). In bivariate analyses, overjet and lip incompetence were significantly associated with TDI. Overjet remained positively associated with severe trauma in multivariate analysis, OR = 1.4, 95% confidence interval (CI) [1.2, 1.6], corresponding to an absolute 1.3%, 95% CI [0.7, 1.8], increase in the likelihood of severe trauma, per millimeter of overjet. Children with increased overjet (>3 mm) were 3.8, 95% CI [2.0, 7.4], times as likely to have experienced severe TDI compared with those with ≤3 mm. Overjet is a strong risk factor for TDIs in the primary dentition. Incorporating and operationalizing this information may help TDI prevention and related anticipatory guidance for families of preschool-age children.

World traumatic dental injury prevalence and incidence, a meta-analysis-One billion living people have had traumatic dental injuries

Traumatic dental injuries (TDIs) account for a considerable proportion of bodily injuries. Nevertheless, global TDI frequency is unknown, probably because TDI diagnosis is not standardized. This study estimated world TDI frequency. A literature search (publication years 1996-2016) was aimed at covering as many countries, communities, ethnic groups as possible, thus achieving high generalizability. In particular, non-specific keywords, no language restrictions, and large databanks were used. Observational studies reporting proportions of individuals with at least one TDI (prevalence) and who developed TDI (incidence rate) were considered. Prevalence rates to permanent dentition, primary dentition and in 12-year-olds, incidence rate to any tooth for any age, male-to-female prevalence ratio (PR) in 12-year-olds, with 95% confidence intervals (95 CIs), were extracted/calculated. Study quality, Z-score distribution, funnel plot symmetry analysis, between-study heterogeneity, sensitivity, and subgroup analyses were performed. Selected primary studies were 102 (permanent dentition; 268 755 individuals; median age, 13.8 years), 46 (primary dentition; 59 436 individuals; median age, 3.4 years), 42 (12-year-olds; 33 829 individuals), 11 (incidence rate; 233 480 person-years; median age, 7.8 years), and 31 (PR; 16 003 males, 16 006 females). World TDI frequency resulted as follows: permanent dentition prevalence 15.2% (95 CI, 13.0%-17.4%); primary dentition prevalence 22.7% (95 CI, 17.3%-28.7%); 12-year-olds prevalence 18.1% (95 CI, 15.3%-21.0%); incidence rate, 2.82 (95 CI, 2.28%-3.42%) per 100 person-years; PR, 1.43 (95 CI, 1.34%-1.52%). Differences between WHO Regions were found. This study shows that more than one billion living people have had TDI. TDI is a neglected condition which could rank fifth if it was included in the list of the world's most frequent acute/chronic diseases and injuries.

The Coronal Tooth Fractures: Preliminary Evaluation of a Three-Year Follow-Up of the Anterior Teeth Direct Fragment Reattachment Technique Without Additional Preparation

Objective:

The aim of this research is to describe and to analyse the long-term results and the clinical steps of direct fragment reattachment technique with no additional tooth preparation, used to treat crown fracture. This technique achieves the clinical success, combining satisfactory aesthetic and functional results with a minimally invasive approach.

Methods:

The 3 years follow-up included 9 patients (5 males, 4 females) with coronal fracture. In all the cases the fragment was available and intact. The authors illustrate the adhesive procedure used. Under local anaesthesia and after positioning the rubber dam, both the tooth and the fragment surface were etched, rinsed and applied by the adhesive system in order to obtain the retention of the fractured part to the tooth without additional tooth preparation or resin cement.

Results:

The statistical analysis shows the good performances of direct fragment reattachment technique. After 36 months, in 22.2% of the cases, the detachment was observed of the bonded fragment and in 11.1% of patients, complications were recorded.

Conclusion:

Our clinical experience shows how the ultra-conservative procedure used is fast, easy and offers a long term predictability; it also allows good functional and aesthetic outcomes.

Incidence of pulp sensibility loss of anterior teeth after paramedian insertion of orthodontic mini-implants in the anterior maxilla

BACKGROUND

The aim of this retrospective investigation was to evaluate the incidence of loss to pulp sensibility testing (PST) of maxillary front teeth after paramedian (3 to 5 mm away from the suture) orthodontic mini-implant (OMI) insertion in the anterior palate.

METHODS

A total of 284 patients (102 males, 182 females; mean age was 14.4 years (±8.8) years at time of OMI-Insertion) with a total of 568 OMIs (1.7 mm diameter, length 8 mm) were retrospectively investigated. A binomial regression analysis was performed to explore covariates, such as age, gender, inclination of upper central incisors, dentition status and insertion position of OMIs that could have contributed to loss of sensibility. Statistical significance was set at p < 0.05.

RESULTS

Loss of response to PST was encountered during retention in 3 out of 284 patients and the respective OMIs had been placed at height of the second rugae (R-2). Affected teeth were a right canine, a left lateral and a left central incisor. Subsequent root canal treatment was successful. Results of the binomial regression analysis revealed that the covariate insertion position (R-2) of OMIs (p = 0.008) had statistically significant influence on loss of response to PST.

CONCLUSIONS

(1) Although there was no radiographic evidence for direct root injury, the proximity of the implants to the anterior teeth was nevertheless statistically related to loss of PST. (2) In all cases of PST loss OMIs were inserted at the second rugae. Therefore OMIs should be placed either more posteriorly, at the third rugae or in the median plane. (3). Loss of PST was not increased for patients with palatal OMI (0.18%) compared to samples without OMI (0.25%).

National Athletic Trainers' Association Position Statement: Preventing and Managing Sport-Related Dental and Oral Injuries

OBJECTIVE

To provide athletic trainers, health care professionals, and all those responsible for the care of athletes with clinical recommendations for preventing and managing sport-related dental and oral injuries.

BACKGROUND

Participation in competitive sports continues to grow at both the interscholastic and intercollegiate levels. Therefore, exposure to, and the incidence of athletic-related injury, including orofacial injury, will also likely increase. At the time of this writing, the leading governing agencies for interscholastic (National Federation of State High School Associations) and intercollegiate (National Collegiate Athletic Association) sports require only protective orofacial equipment (eg, mouthguards) for 5 and 4, respectively, of their sanctioned sports. Although orofacial injuries represent a small percentage of all sport-related injuries, the financial burden associated with these injuries (eg, tooth avulsion) can exceed $15 000 over an adult life. Therefore, effective management of sport-related dental injuries is critical to the long-term financial, physical, and emotional health of people who have experienced dental trauma.

RECOMMENDATIONS

Based upon the current evidence regarding sport-related orofacial injury, we provide recommendations related to planning considerations, education, and mouthguard efficacy, material, fabrication, and care considerations. Additionally, suggested best practices for managing sport-related dental injury are also given for athletic trainers and other health care professionals.

The knowledge, attitude and practices of male sports participants to sports-related dental trauma in Khobar and Dammam, Saudi Arabia - A pilot survey

The risk of dental trauma may increase during sports participation. The purpose of this study was to evaluate the knowledge, attitude, and practices of sports participants concerning sports-related dental trauma and associated emergency/preventive practices. The study included 124 male subjects over 18 years of age participating in contact and non-contact sports in three clubs in the Eastern Province, Saudi Arabia. A questionnaire was used to assess past experience of dental trauma related to sports in addition to the use of a mouth guard and knowledge of related emergency procedures. Outcomes were compared between individuals practicing direct and non-direct contact sports. One third of the participants had experienced dental trauma while playing sports, mostly crown fracture, mobility, and avulsion. Their knowledge of first aid and emergency procedures was inadequate. A significantly higher proportion of non-direct contact sport participants sought the help of a dentist for themselves or others (P = 0.04 and 0.003, respectively). Only 33.9% used mouth guards, with higher odds of mouth guard use associated with participating in direct contact sports and believing a tooth can be lost during sports practice (odds ratio = 5.59 and 5.37, respectively). Educational programs are needed to increase the awareness in sports participants of the risk of dental trauma during sports participation, to improve their knowledge of first aid procedures, and to increase the use of mouth guards.

Pattern of traumatised anterior teeth among adult Nigerians and complications from late presentation

Background

The objectives of this study were to determine the prevalence and pattern of traumatic dental injury (TDI) among adults presenting in a tertiary health care facility in Nigeria, the time interval between injury and presentation in the hospital, the reasons for seeking treatment, and the complications arising due to late presentation.

Methods

Information obtained from history taking and clinical examination included Patient’s demographics, the when, where, and how of the injury, previous history of trauma, time elapsed between injury and presentation at the hospital, reason for seeking treatment, tooth/teeth involved, sensibility, tenderness to percussion, mobility, presence of discolouration, swelling, sinus tract, and mobility. Radiographic findings such as periapical radiolucency, pulp canal obliteration, and root resorption were also documented. TDI was classified using the Andreasen’s classification.

Results

Out of the 2645 adult patients that attended the outpatient clinic, 184 Presented with TDI giving a prevalence of 6.96 %. Their age range and mean age were 17–69 years and 30.6 ± 11.2 years respectively. Falls accounted for most (26.4 %) of the trauma to anterior teeth followed by motor cycle accidents (18.4 %) and domestic accidents (12.9 %), while opening bottle cork accounted for 1.2 %. The most common type of injury was enamel-dentine fracture accounting for 28.8 %, followed by complicated crown fracture 18.6 %, and avulsion 11.7 %. The maxillary central incisors were the most commonly affected followed by the maxillary lateral incisors and canines. More than half (51.5 %) of the patients presented in the hospital more than 1 year after injury. Majority of patients in the age groups ≤20 and 51–60 sought treatment because of pain, while more of those in the age groups 21–30 and 31–40 sought treatment because of aesthetic considerations. Seventy three (45.3 %) of the patients presented with complications involving 138 teeth. Majority of the complications were in teeth with enamel-dentine fracture (93.4 %), followed by concussion injury (55.6 %).

Conclusions

The prevalence of TDI in this study falls within previously reported figures. However, the high number of teeth developing complications may have resulted from late presentation for care.

Classification and Epidemiology of Traumatic Dentoalveolar Injuries in Dogs and Cats: 959 Injuries in 660 Patient Visits (2004-2012)

The objective of this study was to determine the epidemiology of traumatic dentoalveolar injuries (TDI) in dogs and cats and to evaluate the applicability of a human classification system for TDI in dogs and cats. All patients diagnosed with a TDI were identified from the University of Wisconsin-Madison School of Veterinary Medicine Dentistry and Oral Surgery Service case log and the hospital patient processing software. The study population consisted of 621 dogs and cats, in a total of 660 patient visits from 2004 to 2012, admitted for oral treatment and subsequently diagnosed with at least one TDI Medical records including diagnostic imaging studies were reviewed to group the injury according to a classification system used in humans for TDI. Patient signalment, tooth injured, and number of injuries per patient were recorded and tabulated. The overall prevalence of TDI was 26.2%. The mean +/- SD number of TDI per patient was 1.45 +/- 0.85. All 14 classes of TDI recognized by the classification system utilized in humans were identified, and all (100%) TDI identified in this study were classifiable using this system. Enamel-dentin-pulp fracture was the most common TDI (49.6%). The most commonly injured teeth were the mandibular or maxillary canine teeth (35.5%). The most common age for dogs and cats with TDI were 3-6 years (33.0%) and 7-10 years (31.3%). With a frequency of 1 in 4 animals, TDI are common and represent a significant pet health concern. Most TDI are considered severe and require timely, and sometimes immediate, treatment. The adoption and utilization of a complete classification system, such as the one used in this study, is recommended in order to improve future epidemiological study of TDI in animals.

Evaluation of a possible association between a history of dentoalveolar injury and the shape and size of the nasopalatine canal

OBJECTIVES

Maxillary incisors (MI) are often affected by dentoalveolar injury resulting in tooth devitalization and apical periodontitis. The aim of the present study was to analyze any association between a history of dentoalveolar injury and the shape and size of the nasopalatine canal (NC) using cone beam computed tomography (CBCT).

MATERIAL AND METHODS

Patients were allocated to the trauma group if they had a history of dentoalveolar injury and a root filling in at least one MI and/or one missing MI. As controls, 100 matched-controlled (age and gender) patients were selected. NC dimensions including length, width at midway, and diameter of incisal and nasal foramen were measured in sagittal and axial CBCT planes. Furthermore, an evaluation of NC bulging signs, apical osteolysis of MI, and its fusion with NC was performed.

RESULTS

In the trauma group (n = 96), 31.3 % had at least one missing MI, and 95.8 % had a root filling in a MI. The antero-posterior dimension of the incisive foramen (p = 0.02) and of the NC at midway (p = 0.04) was significantly larger in the trauma group. Significantly more cases with a bulging sign were found in the trauma (n = 19) than in the control group (n = 3, p = 0.001). An apical osteolysis was identified in 5.1 % of MI, and 12/38 did show a fusion with the NC.

CONCLUSION

Wider dimensions of the NC and a bulging sign may suggest a former dentoalveolar injury to the anterior maxilla. Periapical osteolysis of central MI over 5 mm in diameter tends to fuse with the NC.

CLINICAL RELEVANCE

In patients with a history of dentoalveolar injury and/or apical periodontitis, the NC should be evaluated on available CBCT images. Any inflammatory processes in the neighboring teeth should be recognized and eliminated as they may initiate bulging of the NC and/or the formation of a nasopalatine duct cyst (NPDC). NC with bulging signs should be monitored clinically and radiographically to diagnose a NPDC in an early stage.

Dentofacial and cranial changes in down syndrome

Objectives

This study aimed to determine the prevalence of certain oral characteristics usually associated with Down syndrome and to determine the oral health status of these patients.

Methods

The cross-sectional study was conducted among patients attending a special education program at Faculty of Dentistry, Jamia Millia Islamia, Delhi, India. The study design consisted of closed-ended questions on demographic characteristics (age, sex, and education and income of parents), dietary habits, and oral hygiene habits. Clinical examination included assessment of oral hygiene according to Simplified Oral Hygiene Index (OHI-S), dental caries according to decayed, missing, and filled teeth (DMFT) index, periodontal status according to the Community Periodontal Index of Treatment Needs (CPITN), and malocclusion according to Angles classification of malocclusion. Examinations were carried out using a using a CPI probe and a mouth mirror in accordance with World Health Organization criteria and methods. Craniometric measurements, including maximum head length and head breadth were measured for each participant using Martin spreading calipers centered on standard anthropological methods.

Results

The majority of the patients were males (n = 63; 82%) with age ranging from 6–40 years. The Intelligence Quotient (IQ) score of the patients indicated that 31% had moderate mental disability and 52% had mild mental disability. 22% exhibited hearing and speech problems.12% had missing teeth and 15% had retained deciduous teeth in adult population. The overall prevalence of dental caries in the study population was 78%. DMFT, CPITN and OHI scores of the study group were 3.8 ± 2.52, 2.10 ± 1.14 and 1.92 ± 0.63 respectively. The vast majority of patients required treatment (90%), primarily of scaling, root planing, and oral hygiene education. 16% of patients reported CPITN scores of 4 (deep pockets) requiring complex periodontal care. The prevalence of malocclusion was 97% predominantly of Class III malocclusions. Further 14% presented with fractured anterior teeth primarily central incisor. The percentage means of cephalic index was 84.6% in the study population. The brachycephalic and hyperbrachycephalic type of head shape was dominant in the Down syndrome individuals (90%).

Conclusion

The most common dentofacial anomaly seen in these individuals was fissured tongue followed by macroglossia.

Validation of the cone beam computed tomography-based stereolithographic surgical guide aiding autotransplantation of teeth: clinical case-control study

OBJECTIVE

To compare the outcome of cone beam computed tomography (CBCT)-based surgical planning and transfer technique for tooth autotransplantation versus conventional autotransplantation.

STUDY DESIGN

The study material comprised 40 pediatric subjects in whom 48 teeth were transplanted following a case-control design. While the study group (mean age 11 years) underwent CBCT imaging for surgical planning and transfer via stereolithographic tooth replica fabrication, the historical control group (mean age 12 years) was subjected to conventional autotransplantation.

RESULTS

The CBCT-based preoperative planning and the use of a tooth replica decreased the extra-alveolar time and reduced the number of positioning trials with the donor tooth. In the control group, 6 patients showed 1 or more complications, while this was noticed for only 2 study patients.

CONCLUSION

CBCT-based surgical planning of tooth autotransplantation may benefit from a shorter surgical time, while being a less invasive technique, causing fewer failures than a conventional approach.

Prevalence of traumatic injuries to permanent dentition and its association with overjet in a Swiss child population

OBJECTIVE

Dental trauma is a very common issue in dentistry and its occurrence has been related to many factors. The aim of this study was to evaluate the prevalence of traumatic dental injuries in the permanent dentition among Swiss children and its association with overjet.

MATERIAL AND METHODS

A sample of 1900 children aged 6-13 years was prospectively evaluated to determine the number and types of injuries, the influence of overjet on the risk of suffering trauma and the relationships between trauma, age, gender and life conditions.

RESULTS

The observed prevalence of trauma was higher for boys, with a slight risk increase with age and a peak frequency at the age of 10 years. Most of the injuries (91.2%) involved the upper front teeth; 87.2% of all injuries were hard tissue injuries (enamel or dentin fractures), and 12.8% only subluxation and luxation injuries. Children with an overjet of 6 mm or more had a four times higher risk of suffering trauma, compared with those with less overjet.

CONCLUSION

This cross-sectional study confirmed most of the results from earlier studies dealing with epidemiological factors of dental injuries to the permanent dentition. Of all the variables analysed, overjet stood out as the most significant risk factor: an increased overjet of 6 mm or more had a major impact on the risk of trauma, which would speak in favour of early orthodontic correction of an increased overjet to reduce the prevalence of dental trauma.

Management of traumatic intrusive luxation of incisors in a patient with Down's syndrome

Special needs individuals are children or adults who are prevented by a physical or mental condition from full participation in the normal range of activities of their age groups. They usually exhibit high treatment needs because of an increased prevalence and severity of trauma. This paper presents a case report and review of treatment strategy of repositioning, splinting of permanent incisors in a 13-year-old boy with Down's syndrome sustaining trauma led to intrusive luxation of maxillary incisors. The intruded incisors were immediately repositioned and splinted with composite within hours.

The association between orthodontic treatment need and maxillary incisor trauma, a retrospective clinical study

OBJECTIVES

Identifying risk factors for dental trauma in children is important. The main aim of this retrospective study was to investigate the association between maxillary incisor trauma (MIT) and variables such as gender, malocclusion complexity, and orthodontic treatment need (OTN).

STUDY DESIGN

ICON (Index of Complexity, Outcome and Need) scores were calculated in 502 schoolchildren (253 girls and 249 boys, aged 11-14-years). Subjects were categorized into 5 ICON complexity groups (easy to very difficult) and into 2 groups according to OTN (ICON >43, ICON <44). Logistic regression was performed to test for any differences in risk of MIT among subjects in different ICON complexity groups and to estimate the predictive value of gender, OTN, and ICON scores for MIT.

RESULTS

Nine percent experienced incisor trauma (93.4% maxilla, 6.6% mandible). Enamel fracture was the most common type (6.2%) of dental trauma. Boys had greater odds of MIT compared with girls (odds ratio [OR] 2.16, 95% confidence interval [CI] 1.11-4.21). Subjects with OTN showed greater odds of MIT compared to those without (OR 2.37, 95% CI 1.21-4.64). Only subjects presenting with difficult complexity grade (64 < ICON < 77) showed significantly higher odds of experiencing MIT (OR 3.16, 95% CI 1.25-8.01) compared with the easy complexity group (ICON <29).

CONCLUSION

The higher risk of experiencing MIT in malocclusions with difficult complexity warrants more vigilant screening of this group before and during dental or orthodontic treatment.

An investigation into the association between facial profile and maxillary incisor trauma, a clinical non-radiographic study

OBJECTIVES

To explore the association between maxillary incisor trauma (MIT) and facial skeletal forms (sagittal and vertical), overjet (OJ), lip coverage, and gender.

SUBJECTS AND METHODS

Five hundred and two subjects (253 females and 249 males, aged 11-14 years) were examined. Sagittal (Class I, II or III) and vertical skeletal pattern (average, increased or decreased Frankfort-Mandibular Plane Angle (FMPA)) were recorded. Samples were categorized into four groups according to OJ severity: OJ ≤ 3.5 mm, 3.5 mm < OJ ≤ 6.0 mm with competent lips, 3.5 mm < OJ ≤ 6.0 mm with incompetent lips and OJ > 6 mm. Samples were also subdivided into two groups: OJ ≤ 3.5 mm and OJ > 3.5 mm. Chi-square test was performed to determine any gender differences in trauma experience. Logistic regression was performed to test for any differences in risk of MIT in different groups, and to estimate the predictive value of facial skeletal pattern (sagittal), FMPA, gender, OJ, and lip competence for MIT.

RESULTS

Nine percent had incisor trauma (8.4% MIT). Boys had greater odds of receiving MIT than girls (OR = 2.16; 95% CI, 1.11-4.21). Subjects with Class II skeletal patterns had greater odds of MIT than those with Class I skeletal patterns (OR = 3.98; 95% CI, 1.98-8.00). Subjects with decreased FMPA had greater odds of MIT than subjects with average FMPA (OR = 4.55; 95% CI, 2.28-9.06). Lip competence was not associated with MIT (P > 0.05). Subjects with OJ > 3.5 mm had greater odds of MIT than subjects with OJ ≤ 3.5 mm (OR = 2.83; 95% CI, 1.49-5.37).

CONCLUSION

Compared with children with normal OJ (≤3.5 mm), Class I skeletal pattern (Straight profile) and average FMPA, the odds of MIT increased significantly in children with OJ > 3.5 mm (OR = 2.83), Class II skeletal pattern (OR = 3.98) and decreased FMPA (short face profile) (OR = 4.55), respectively.

Prevalência de traumatismo dentário e fatores associados em escolares do município de Palhoça (SC)

O aumento dos níveis de violência, do número de acidentes de trânsito e uma maior participação das crianças em atividades esportivas contribuem para transformar o traumatismo dental em um problema de saúde pública emergente. Todavia, ainda há carência de dados que mostrem o comportamento deste agravo no Brasil. O objetivo desse estudo foi conhecer a prevalência de traumatismo na dentição permanente e fatores associados em escolares de doze anos de idade de Palhoça (SC). Foi realizado um estudo transversal envolvendo uma amostra representativa dos escolares (n=405). Os critérios de classificação do traumatismo foram os mesmos usados no levantamento nacional do Reino Unido. Testou-se associação entre a prevalência e fatores clínicos e socioeconômicos por intermédio do qui-quadrado. A prevalência encontrada foi de 22,5%, sendo estatisticamente maior no sexo masculino. A maioria dos danos traumáticos foram de pequena magnitude, mas encontrou-se alta necessidade de tratamento entre os dentes passíveis de tratamento imediato. Pode-se concluir que foram altas a prevalência e a necessidade de tratamento do traumatismo dentário em Palhoça. A prevalência não mostrou associação com fatores socioeconômicos ou clínicos.
