Assessment of the willingness of Nigerian Orthodontists to offer face-to-face orthodontic services to patients infected with Covid-19.

Introduction: Efforts to contain the spread of the COVID-19 disease led to suspension of many services which caused orthodontists to resort to providing only emergency services. The aims of this study were to assess the willingness of Nigerian Orthodontists and Orthodontic resident doctors to treat patients infected with Covid-19 as well as to ascertain advice given regarding traumatic arch wires and aligners during the pandemic. Participants and study design: This was a descriptive cross-sectional study. We included dentists who were Orthodontists and orthodontic resident doctors practicing in Nigeria. Data was collected via an online questionnaire (Google form) which was sent three times weekly throughout May/June, 2020 and analysed using SPSS version 23. Descriptive statistics were used to analyse the data. Results: Forty-eight out of the 90 members of the WhatsApp group responded within the allotted time, giving a response rate of 53.3%. Out of a total of 48 respondents, 39 (81.3%) were unwilling to treat patients infected with COVID-19 during the pandemic. The major reason was fear of infection with the virus (12, 25.0%). Most of the respondents (41, 55.4%) suggested the use of wax for relief of trauma from arch wires. Conclusion: Majority of Orthodontists and orthodontic residents practicing in Nigeria expressed unwillingness to treat patients infected with COVID-19. Aligner therapy was proffered as an alternative to bracket therapy.

COVID-19 risks and extra-protective measures practised among Nigerian orthodontists and orthodontic residents.

BACKGROUND AND AIMS: There is a high possibility of transmitting the coronavirus (severe acute respiratory syndrome coronavirus 2) in the orthodontic clinic because orthodontists and their patients are in very close contact when orthodontic care is being given. The aim of this study was to evaluate the knowledge and perception of Nigerian orthodontists and orthodontic residents about the risks of COVID-19 as well as the extra-protective infection control measures that need to be taken. MATERIALS AND METHODS: This was a descriptive, cross-sectional study. The questionnaires were distributed and retrieved from consenting participants through an online platform. The questionnaires were analysed using the Statistical Package for the Social Sciences software version 23. The results were presented in tables and charts. RESULTS: Out of a total of 90 members on the association's WhatsApp group as at the time the study was being conducted, a total of 48 respondents participated in this study. There were more females (60.4%) than males. Majority (97.9%) of the respondents agreed/strongly agreed that an infected patient could infect the orthodontic clinic staff members with COVID-19 while most were of the view that debonding (95.8%) and retainer delivery (70.8%) posed a risk for spread of the virus. More than half of the respondents (52.1%) considered it necessary to change N95 masks after each patient as an extra-protective measure against COVID-19. CONCLUSIONS: Majority of the respondents knew about the risks that COVID-19 posed to different aspects of orthodontic practice and were also knowledgeable about some of the extra-protective measures that they should take. There is a need to improve the knowledge of the participants concerning the use of appropriate mouth rinses to reduce the risks of transmission of COVID-19 in the dental/orthodontic clinic.

The COVID-19 pandemic and orthodontic practice in Nigeria.

OBJECTIVES: This study was aimed at assessing the knowledge and awareness of orthodontists and orthodontic residents in Nigeria about the COVID-19 pandemic and the appropriate infection control measures required to mitigate its spread in orthodontic practice. MATERIALS AND METHODS: It was a cross-sectional descriptive study of orthodontists and orthodontic residents. Ethical approval for the study was obtained from the Institutional Review Board. Data collection was via an online questionnaire designed using Google forms and these were sent to the phone numbers of study participants. Data analysis was done using Statistical Package for Social Sciences version 20. RESULTS: A total of 73 respondents with a mean age of 43.41 ± 9.21 years participated in the study. About 90% of the respondents had a very good knowledge of COVID-19, including its etiology, modes of transmission, signs, and symptoms. However, very few respondents were aware of the less common symptoms such as skin rash (16.4%) and red eyes (26%). Over 80% of the respondents knew the appropriate measures to take to prevent the spread of the virus in the dental clinic, in addition to the appropriate personal protective equipment (PPE) to use. CONCLUSION: The respondents had a very good knowledge of the basic epidemiology of COVID-19 and the means of prevention of its transmission in the dental clinic. However, there was limited knowledge of the less common symptoms of the infection. In addition, majority of the respondents had a very good idea of the appropriate PPE to be used.

Perceived impact of the COVID-19 pandemic on orthodontic practice by orthodontists and orthodontic residents in Nigeria.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) pandemic has had far-reaching effects on orthodontic care delivery worldwide. This study aimed to assess the impacts of the pandemic on orthodontists and orthodontic residents in Nigeria. METHODS: This cross-sectional study was conducted among consenting orthodontists and orthodontic residents. The respondents were contacted through the WhatsApp group of the Nigerian Association of Orthodontists to fill the self-administered online questionnaires (Google forms). The questionnaire had two sections: A, Sociodemographics; B, Perceived impact of the COVID-19 pandemic. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics were used to compute mean and standard deviation and chi-square for association. Level of significance was set at P < 0.05. RESULTS: This study population comprised 98 people; however, only 73 participants responded, which represented a response rate of 74.5%. Approximately 60% (44) of the respondents thought that the COVID-19 pandemic would lead to a reduction in the number of orthodontic patients in the future, whereas almost all the respondents reported that it would affect their future practice of orthodontics. Most of the respondents (63.0%) reported that the pandemic had recorded a moderate to severe negative economic impact on them. Significant gender differences were recorded, in the social life of respondents, in addition to economic and psychosocial effects. CONCLUSIONS: Almost all respondents reported that they would change their future practice of orthodontics, particularly with respect to placing a greater emphasis on infection control. Most of the respondents reported perceived economic, psychosocial, and social impacts due to the pandemic.

Self-perception of dental appearance and aesthetics in a student population.

OBJECTIVE: To assess the perception of personal dental appearance and dental aesthetics of a young adult population and to compare this with their normatively assessed orthodontic treatment need. MATERIALS AND METHODS: This was a cross-sectional study involving 420 undergraduate students aged 18-30years, with no previous history of orthodontic treatment. Objective assessment of dental aesthetics was carried out using the aesthetic component of the Index of Orthodontic Treatment Need (IOTN), while self-administered questionnaires were used to assess perception of personal dental appearance. RESULTS: Over 90% of the students considered healthy and well-arranged teeth to be important to their appearance, however, only 36% of them were satisfied with their dental aesthetics. In addition, three-quarters (75%) of the students reported that they desired to change the appearance of their teeth, majority (56.5%) wanted to change the colour, whilst 31.2% wanted to change the arrangement of their teeth (31.2%). A statistically significant association (P=0.05) was recorded between the level of satisfaction with their dental aesthetics and an objective assessment by an orthodontist. CONCLUSION: The two most important features in the perception of their personal dental appearance, for this young adult population, were the 'colour' and 'arrangement' of their teeth. There was a statistically significant association between their satisfaction with their dental aesthetics and their normatively assessed orthodontic treatment need, although no correlation was observed between both variables.

Malocclusion and early orthodontic treatment requirements in the mixed dentitions of a population of Nigerian children.

INTRODUCTION: The aims of this study were to establish the prevalence of dental features that indicate a need for early intervention and to ascertain the prevalence of different methods of early treatment among a population of Nigerian children in mixed dentition. METHODS: Occlusal relationships were evaluated in 101 children in mixed dentition between the ages of 6 and 12 years who presented at the Orthodontic Unit, Department of Child Dental Health, Lagos University Teaching Hospital over a 2 years period. The need for different modes of early orthodontic treatment was also recorded. RESULTS: Anterior tooth rotations (61.4%) and increased overjet (44.6%) were the most prevalent occlusal anomalies. Others included deep bite (31.7%), reverse overjet (13.9%), and anterior open bite (14.8%). Severe maxillary spacing and crowding were exhibited in 12.0% and 5.0%, respectively. About a third (35.7%) of the subjects presented with crossbite while lip incompetence was observed in 43.6% of the subjects. About 44% of the subjects also presented with various oral habits with digit (15.8%) and lip sucking (9.9%) being the most prevalent. Subjects were recommended for treatment with 2 by 4 fixed orthodontic appliances (22.3%), habit breakers (20.7%), removable orthodontic appliances (16.5%), and extractions (15.7%). CONCLUSIONS: Increased overjet and anterior tooth rotation were the majority of occlusal anomalies seen, which are not only esthetically displeasing but may also cause an increased susceptibility to trauma to these teeth. Treatment options varied from extractions only to the use of appliance therapy.

Orthodontic Treatment Need and Complexity among Nigerian Adolescents in Rivers State, Nigeria.

Introduction. The assessment of orthodontic treatment need and complexity are necessary for informed planning of orthodontic services. The aim of this cross-sectional study was to assess these parameters using the Index of Complexity, Outcome, and Need (ICON) in a Nigerian adolescent population in a region where orthodontic services are just being established. Methods. Six hundred and twelve randomly selected Nigerian adolescents aged 12 to 18 years were examined using the ICON in their school compounds. Descriptive statistics were employed in the data analysis. Results. Out of a total of 38.1% of the population found to need orthodontic treatment, there were more males and older adolescents. The overall mean ICON score for the population was 39.7 ± 25.3 SD with males having statistically higher mean ICON score. The grades of complexity of the population were 21.6% for very difficult and difficult, 7.5% moderate, and 70.9% mild/easy. Conclusions. Although just over a third of the adolescents were found to have a need for treatment, about a quarter of them were found to have difficult and very difficult complexity grades indicating a need for specialist care. The authors recommend the training of more specialist orthodontists in this region.
