Topic: Research Focus

Description:

My research focus is on aetiological factors and epidemiology of malocclusion with specific emphasis on:

1. General and Local factors related to malocclusion: Using descriptive and analytical studies, 

- I investigated association of general factors (genetics, ethnicity, skeletal pattern and systemic diseases) and local factors (frenal attachments, digit sucking and tooth abnormalities and malposition), with malocclusion.

- These were achieved through investigation into genetic basis for sub-phenotypic classification of skeletal malocclusion, epidemiology of malocclusion as well as intervention studies for effective diagnosis and treatment of malocclusion.

- I aim to utilize the results of these research to establish diagnostic templates for automatic diagnosis of dentofacial deformities, as well as prediction of prognosis of orthodontic treatment outcome.

2. Access to Orthodontic care:

- This was aimed at identifying the status of clinical orthodontics, and those factors that may affect the clinicians' ability to provide the care (motivations and job satisfaction, occupational stress, work life balance, mitigation of aerosol and spatter in the operatory, anxiety related  to Covid-19 pandemic).

- From the patients' perspectives, factors that may affect their access to orthodontic care were examined (age at presentation, psychological impact of malocclusion and self esteem, motivation and cooperation with treatment).

- I aim to use the results of these research to design strategies for improvement in demand for orthodontic care as well as recruitment into orthodontic training with the aim of improved retention of orthodontic educators and clinicians.

Comparative Study of Tooth Size And Arch Dimensions in Crowded, Spaced and Normal Occlusion in a Population of Nigerian Adults

Background: The integrity of the dental arch is maintained by coordination between the dimensions of the teeth and dental arches. A discrepancy between these dimensions can lead to dental crowding or spacing and is therefore usually carefully considered in orthodontic treatment planning to ensure optimal treatment outcome. However, the degree of contribution of tooth and dental arch dimensions to crowding or spacing is still unclear.

Objectives: This study aims to investigate the relationship between mesiodistal tooth widths and dental arch dimensions and their influence on space anomalies in a Nigerian population. It also aims to evaluate differences in the influence of mesiodistal tooth size and arch dimensions on space anomalies based on gender and geographical area of origin.

Materials and Method:  Using multi-stage sampling, 240 adults from the Northern region of Nigeria and another 240 adults from the Southern region of Nigeria will be selected with equal gender representation. Each cohort will be categorized into normal, crowded, and spaced arches based on space analysis of maxillary and mandibular dental casts by subtracting the sum of mesio-distal (MD) dimensions of all teeth, except the permanent molars, from the arch perimeter. Tooth and arch variables will be compared within and across groups using ANOVA and student's t-test while correlation matrix for the variables will be computed to identify correlations between the variables within the three groups. A stepwise multiple regression analysis with automatic sequential deletion of the least significant variables will be employed to examine the relationship between the measured variables, gender and geographical location, aiming to evaluate their contribution to dental spacing and crowding.
