Tooth injuries: Knowledge of parents of public school students from the city of Alfenas, Minas Gerais, Brazil

Traumatic dental injuries in children: experience during the Covid-19 pandemic and parents' knowledge about their management

The social isolation measures adopted during the critical phase of the COVID-19 pandemic led children to spend most of their time at home. Isolation may alter the pattern of traumatic dental injury occurrences, inasmuch as studies point out that most traumatic accidents occur at home. Considering this scenario and the influence of emergency management on the prognosis of the injury, the aim of this study was to evaluate the experience of traumatic dental injuries in children before and during the pandemic, and the knowledge of this topic by the children's guardians. This cross-sectional study was conducted with guardians of children aged 0 to 6 years, residing in Juiz de Fora, MG, Brazil. The guardians answered an online questionnaire addressing personal information, traumatic dental injury experience before and during the pandemic, and knowledge of this topic. Descriptive and statistical analyses were performed using Pearson's chi-square test at a 5% significance level. The total sample consisted of 343 volunteers. A total of 95 and 92 injuries were reported before and during the pandemic, respectively; the home was the place of greatest occurrence. Most volunteers (88.1%) agreed that traumatic dental injuries are emergency situations, and were aware that the tooth/fragment had to be taken to the dentist after a fracture or avulsion (97.4%). This study revealed that the traumatic dental injury experience was similar before and during the pandemic, and that the volunteers had satisfactory knowledge, especially in recognizing the importance of immediate attention for a more favorable prognosis of these injuries.

Can parents prevent tooth loss related to dental avulsion? An assessment of knowledge related to permanent teeth

Purpose

Dental avulsion injuries have a poor prognosis that largely depends on the immediate steps taken to manage the avulsed tooth. A lack of knowledge about the initial management can lead to tooth loss, with further adverse implications for esthetics, phonetics, and overall growth and function. Hence, the present study aimed to assess parents' knowledge regarding dental avulsion and the variables associated with their knowledge of avulsion injuries.

Methods

A series of closed-ended questions on parents' knowledge regarding avulsion, such as immediate management, storage media, handling, and urgency of visiting the dentist, was asked. Univariate associations between the outcomes were assessed using the Pearson chi-square test. The chi-square goodness-of-fit test was used to check whether the sample data were representative of the population.

Results

In total, 211 mothers and 149 fathers were included, of whom 46.7% had experienced dental trauma during their own childhood. Sixty-one percent of mothers believed that they knew everything necessary about tooth avulsion and its management. A significant number of participants who thought that they had a good level of knowledge about avulsion chose water, tissue, or paper wrap to transport the tooth, and preferred tap water, alcohol, or antiseptic to clean the avulsed tooth.

Conclusions

Both mothers and fathers had poor knowledge about tooth avulsion, indicating that there is an immediate need for educational programs focusing on this issue. Since a substantial proportion of participants believed incorrect information, it is vital to disseminate accurate information.

Attitudes and emotional status of parents regarding traumatic dental injuries

BACKGROUND/AIMS

Traumatic dental injuries have different effects on children and their parents, depending on the type of trauma and whether it is in primary or permanent teeth. Parents do not always seek immediate intervention for their children after each traumatic dental injury unless accompanied by conditions such as pain or bleeding that will increase emotional stress. The aim of this study was to evaluate the emotional status of parents and parents' attitudes toward urgent intervention for different traumatic dental injuries in both primary and permanent teeth.

MATERIAL AND METHODS

A questionnaire consisting of two parts was designed with a reliability coefficient of 0.87 according to the results of a pilot study. The questionnaire was sent to parents as a Google Form via online communication methods such as WhatsApp and e-mail. The first part included questions about the demographic data of the parents and children, and the second part consisted of images of traumatic dental injuries of primary and permanent teeth with questions to evaluate the emotional state of the parents and awareness of the necessity for urgent intervention. The Visual Analog Scale (VAS) was used to evaluate the emotional state, and "Absolutely yes;" "Yes;" "I don't have an idea;" "No;" and "Absolutely no" statements were used to evaluate parents' attitudes about urgent intervention. Categorical variables were shown as numbers and percentages and analyzed with Pearson chi-square. Statistical significance was evaluated for p < .05, and correlations between variables were calculated with Pearson correlation.

RESULTS

The survey was completed by 845 parents. All traumatic injuries except extrusion (p = .202; p ≥ .05) had statistically different VAS scores for primary and permanent teeth (p < .05). Parents' attitudes for urgent intervention were statistically significant for all traumatic injuries (p < .05) except 4-mm intrusion (p = .062; p ≥ .05), alveolar fracture (p = .282; p ≥ .05), complicated crown fracture (p = .136; p ≥ .05), and non-traumatized healthy teeth (p = .110; p ≥ .05).

CONCLUSIONS

Traumatic dental injuries with excessive bleeding or tissue loss affect the emotional status of parents more than simple injuries, and they prefer to refer to dentists immediately. Parents responded with higher VAS scores and stronger desires for urgent intervention for permanent teeth injuries compared with primary teeth injuries which shows that parents still do not care about primary teeth as much as permanent teeth.

Effectiveness of an educational cartoon animation on the knowledge of children about traumatic dental injuries

BACKGROUND/AIM

Although children are frequently exposed to traumatic dental injuries (TDIs), their knowledge and attitude regarding the emergency management of TDIs are largely insufficient. The aim of this study was to determine the knowledge of children about TDIs utilizing a questionnaire before and after watching a custom animated instructional video.

MATERIAL AND METHODS

The study was conducted with 332 children aged 8 to 13 years. The children were asked to complete a 3-part questionnaire that included socio-demographic data, past experiences related to TDIs, and knowledge of the emergency management of TDIs. An educational video containing evidence-based information about the management of TDIs was shown to the children. They then completed the questionnaire again immediately after viewing the video and 1 week later. The data were analyzed using Friedman's two-way ANOVA by ranks test, McNemar's test, and the Mann-Whitney U-test.

RESULTS

The children's scores increased significantly following the viewing of the video (p = .0001). Prior to watching the animation, children who had previously received dental trauma education had considerably higher scores than their peers (p = .004). The animation was considered to be beneficial by 96.7% of the children. Prior to watching the animation, 49.1% of the children believed they could help their friends in the event of dental trauma, and after viewing the animation, this rate increased to 86.4%, but decreased to 77.1% after 1 week (p < .001).

CONCLUSIONS

After watching the video, the children's scores improved dramatically and their self-confidence in helping their friends in the event of dental trauma increased.

Perceived Practitioner Barriers to the Management of Orofacial Pain in the Kingdom of Saudi Arabia: A Cross-sectional Study

Background:

Orofacial Pain (OFP) is a group of non-dental painful conditions affecting the oral cavity and facial area.

Objectives:

The objective of this study was to explore which barriers to manage the patient with chronic OFP as perceived by general dentists versus dental specialists and to investigate whether if professionals with degrees from their home country versus another country or number of years of professional experience differ in their perceptions.

Methods:

A closed-end questionnaire was hand-delivered to 600 participants [300 general dentists and 300 dental specialists] in four major provinces in Saudi Arabia. Demographic data were expressed as frequency. Proportional t-tests and chi-square tests were used to analyse intergroup differences. Statistical significance for all analyses was set at P-value < 0.05.

Results:

Overall, the response rate was 56.6% (340/600). Around two-thirds of the participants were general dentists (60.9%), while the remainder were dental specialists (39.1%). There was an obvious consensus by the participants that “Low payment/reimbursement” and “Lack of OFP knowledge” were among the most common barriers (85% and 83.5%, respectively). In contrast, “Legal risks” were the least frequently reported factor (38.8%). The most commonly reported barrier by general dentists was “Shortage of patients/lack of demand;” this was significantly different from the experience of dental specialists (87% vs. 72.2%; P- value < 0.01). In terms of the country of graduation or years of experience, there were no significant differences.

Conclusion:

The study demonstrates the existence of many significant barriers other than OFP knowledge, such as reimbursement, facility and demand that could present obstacles and challenges to the management of OFP by general dentists and dental specialists. Most participants believed that dentists should manage this condition and that OFP courses should be included in the dental school curriculum.

Knowledge of Australian primary education providers towards dental avulsion injuries: a cross-sectional study

BACKGROUND/AIM

The aim of this study was to evaluate the knowledge of school professionals regarding the emergency management of dental avulsion.

METHODS

This cross-sectional study utilised a self-administered, pilot-tested questionnaire for school staff from primary schools. Descriptive statistics were used for the analysis - the prevalence and univariate associations between a categorical outcome and the variables under consideration, were evaluated using Pearson's Chi-squared test.

RESULTS

This survey yielded a response rate of 43.5% (n = 313). Approximately 60% of participants held valid first-aid certificates and 23% had received avulsion advice previously. Over 80% of participants expressed an unwillingness to replant an avulsed tooth, and over 90% believed that there should be greater awareness in this area. This unwillingness to replant was influenced by respondents' age (x2 = 8.13 df = 3, P = 0.043) and receiving advice previously (x2 = 13.15, df = 1, P < 0.001). Under-preparedness was related to years of experience (x2 = 15.03, df = 5, P = 0.010), first-aid training (x2 = 6.41, df = 1, P = 0.011) and receiving advice previously (x2 = 43.47, df = 1, P < 0.001). It was also evident that first-aid training positively influenced appropriate dental referral in the management pathway (x2 = 10.49, df = 1, P = 0.001).

CONCLUSION

This study suggests that there is an inadequate level of knowledge on the appropriate management of dental avulsion injuries amongst primary school professionals in Australia.

Anti-inflammatory and anti-resorptive efficacy of adrenergic blockers on late replanted rat incisors

BACKGROUND/AIM

In addition to their anti-inflammatory and anti-osteoclastogenesis properties, adrenergic blockers may also have promising anti-resorptive effects that can prevent root resorption when teeth are replanted because of avulsion. The aim of this study was to investigate the effects of phentolamine (Ph) and propranolol (Pr) in gels on the repair process of late replanted rat incisors. A further aim was to evaluate the biocompatibility of both drugs to human periodontal ligament fibroblasts (HPDLFs).

MATERIALS AND METHODS

Forty-eight maxillary right incisors were extracted from male Wistar rats, stored in paper napkins for 60 minutes, and randomly allocated to one of eight groups (n = 6). The root canal, root surface, and alveolus were treated with 0.75 µg/mL Ph gel (Ph0.75), 10 µg/mL Ph gel (Ph10), 100 µg/mL Ph gel (Ph100), 2.5 µg/mL Pr gel (Pr2.5), 10 µg/mL Pr gel (Pr10), 100 µg/mL Pr gel (Pr100), or sodium carboxymethylcellulose gel (CMC) before replantation. In the control group (CH), only the root canal was treated with calcium hydroxide paste. Thirty days following surgery, the animals were euthanized, and the right hemimaxilla was removed to perform micro-CT and histomorphometric analysis to determine osteoclastic activity. Ethanolic solutions of Ph10 and Pr10 were selected based on the in vivo study, and the viability of HPDLFs stimulated with lipopolysaccharide was determined by MTT assays.

RESULTS

The micro-CT and histomorphometric analysis revealed no significant differences among the treatments (P > .05). The presence of active osteoclasts was significantly decreased in the Ph10 and Pr10 groups (P < .05). Ph10 and Pr10 produced statistically similar cell survival rates compared to the control group (P > .05).

CONCLUSIONS

Ph10 and Pr10 significantly decreased osteoclastogenesis in delayed replanted rat teeth and were not cytotoxic toward HPDLFs.

Role of Computed Tomography Scan in Dental Trauma: A Cross-Sectional Study

Background:

Dental trauma is caused by fracture(s) in the vertical plane and the horizontal plane of roots. The objective of this study is to perform multiple diagnostic modalities for the diagnosis of horizontal root fracture(s) of the tooth.

Methods:

A total of 250 patients with dental complaints were subjected to intraoral radiography, multidetector helical computed tomography (MDHCT), and limited cone beam computed tomography (LCBCT). The suspected tooth was extracted, visually inspected, and subjected to microcomputed tomography (micro-CT). Images were observed in the lightbox, and a fracture was considered if it had been directly visualized as radiolucent line traversing tooth root. Wilcoxon test/Tukey post hoc test was performed at 99% of confidence level.

Results:

With respect to visual inspection, for LCBCT, intraoral radiography, MDHCT, and micro-CT, sensitivities were 0.988, 0.972, 0.967, and 0.979; accuracies were 0.956, 0.785, 0.905, and 0.888; false-positive values were 5, 21, 12, and 11; and false-negative values were 3, 24, 3, and 11, respectively. The area of the image visible at one time was in the order of treatment without radiography < intraoral radiography < MDHCT < micro-CT < LCBCT.

Conclusion:

The LCBCT had the highest sensitivity and accuracy for diagnosis of horizontal tooth root fracture(s).

Manejo endodôntico de dentes reimplantados: revisão de literatura

O reimplante dentário destaca-se como um procedimento conservador, sendo a conduta não-protética que pode ser realizada em casos de avulsão, evitando sequelas estéticas, funcionais e psicológicas junto ao paciente. Para controlar os processos reabsortivos que se desencadeiam devido a lesão no ligamento periodontal, o tratamento endodôntico se faz necessário. Objetivo: apresentar uma revisão de literatura sobre o manejo endodôntico de dentes reimplantados, elucidando os aspectos clínicos, radiográficos e fisiológicos envolvidos no processo e, também, confeccionar um guia de consulta para prática clínica. Conclusão: O reimplante dentário auxilia no aspecto psicológico decorrente da perda dentária, sendo a endodontia uma etapa fundamental no processo. Ao final do tratamento Endodôntico de um dente re-implantado, com uso da medicação intracanal adeaquada, a saber hidróxido de cálcio,  espera-se um dente clinicamente assintomático e radiograficamente ausência de sinais de reabsorção e lesão apical. Contudo, o  acompanhamento clínico e radiográfico do paciente deve ser feito por pelo menos cinco anos.
