Current Research and Capacity Building Projects including Grants.

1. TITLE: ROOT AND CANAL MORPHOGIES AMONG NIGERIANS: A CONE BEAM COMPUTED TOMOGRAGPY ANALYSIS.
This study is divided into three parts: A case report titled: Single-rooted mandibular second molar with a single canal.
A case series: Radiographic determination of anomalous root canal morphology in patients with pulpal diseases at the University College Hospital, Ibadan, Nigeria.
A survey titled: Root and canal morphologies among Nigerians: A Cone Beam Computed Tomography analysis.
FUNDER: The case report and series were self-funded; however, a grant is being sought for the comprehensive full-scale national survey.
BRIEF SUMMARY: The case report details the successful endodontic management of a rare single-rooted mandibular second molar with a single canal, leveraging Cone-Beam Computed Tomography (CBCT) for precise diagnosis. A case series further explores anomalous root canal morphology in molars and premolars, emphasizing the crucial role of advanced imaging in treatment planning and overall clinical efficacy. An observational cross-sectional survey involving 205 adult Nigerian participants utilizing CBCT to analyze root and canal morphologies, anticipating unique patterns and distributions. The ensuing data analysis, performed using IBM SPSS version 23, applies descriptive and inferential statistics to provide insights into root canal morphology and anomalies specific to the Nigerian demographic.

Digital radiology, CBCT, and Micro-Computed Tomography (Micro-CT) are some of these contemporary advances. Cone-Beam Computed Tomography is notable among the advanced radiography because it is safe, non-invasive, provides a narrow field of view, associated with lower radiation exposure, has higher spatial resolution, and provides a three-dimensional view.

The study not only addresses the intricacies of the root canal system but also contributes valuable information to advance endodontic practices, emphasizing the significance of detailed root canal system understanding for improved clinical outcomes and treatment efficacy.
ROLES: Conceptualization and design: Formulating research questions, hypotheses, and study design.

2. TITLE: Noncommunicable diseases and the risk of dental caries, periodontal diseases, and tooth loss in a tertiary health facility.
FUNDER: Department of Restorative Dentistry Research Group
BRIEF SUMMARY: This cross-sectional study in South-west Nigeria investigates the susceptibility of diabetic and cardiovascular disease (CVD) patients attending Endocrinology and Cardiology clinics to dental caries, periodontal diseases, and tooth loss. The 200 subjects are categorized into well-controlled and poorly-controlled groups based on blood pressure and hematological test values. In-depth intra-oral examinations will assess the DMFT index and periodontal health status. Data will be analyzed using IBM SPSS version 23, with statistical significance set at ˂0.05.

The study anticipates an inverse correlation between diabetic control and the likelihood of periodontitis, dental caries, and tooth loss. Similar outcomes are expected for cardiovascular disease patients. This research illuminates the intricate connection between CVD, diabetes, and oral health, providing insights for better chronic condition management.

The findings will serve as a foundation for healthcare professionals, enhancing their understanding of the interplay between CVD, diabetes control, and oral health risks. Ultimately, the study's insights will inform targeted interventions to mitigate adverse effects on dental outcomes in individuals with chronic health conditions, emphasizing the need for comprehensive care.

3. TITLE: The impact of Body Mass Index (BMI) on the clinical outcomes of endodontic treatment in adult patient at the University College Hospital, Ibadan, Nigeria.
FUNDER: Self-funded
BRIEF SUMMARY: This research investigates the correlation between Body Mass Index (BMI), a key anthropometric indicator of health and nutrition, and endodontic outcomes in adults, acknowledging the global and Nigerian prevalence of overweight and obesity. Focusing on the relationship between BMI and endodontic disease, as well as inter-appointment and post-operative endodontic pain, the study delves into the potential impact of systemic conditions, particularly BMI, on pain following Root Canal Treatment (RCT). The research considers factors such as gender, tooth type, and periapical lesion size to comprehensively assess the multifaceted nature of these interactions. Given conflicting reports on BMI's association with oral health, this study aims to bridge existing knowledge gaps. Employing a cross-sectional design with 201 adult participants undergoing RCT, data on BMI, pulp vitality, and pain experiences are meticulously collected and statistically analyzed using IBM SPSS version 23. Anticipated outcomes aim to discern whether BMI significantly influences the prevalence and outcomes of endodontic disease. This research contributes valuable insights to the subtle interplay between BMI and oral health outcomes, addressing a critical gap in understanding for enhanced pain management and treatment efficacy in endodontics.

4. TITLE: Self-reported satisfaction with implant retained prostheses in a Tertiary Institution, South-west, Nigeria.
FUNDER: Self-funded
BRIEF SUMMARY: This study employs a detailed questionnaire to examine patient satisfaction with implant-retained prostheses. Information on demographics, medical history, and implant specifics, including gender, age, occupation, education, and marital status, is being gathered. Participants evaluate satisfaction levels on a 0-10 scale for current implants compared to prior replacements, covering aspects such as overall satisfaction, esthetics, chewing ability, self-confidence, and complications. The survey also delves into cost perception, willingness for future implant therapy, the source of therapy suggestion, timing of tooth extraction to implant placement, follow-up attendance, and general comments. This comprehensive approach provides a holistic understanding of patient perspectives, aiding in refining implant treatments for improved outcomes. The outcomes will inform practitioners and contribute valuable insights to enhance the overall quality of implant therapies.

5. TITLE: Exploring Tooth Wear Lesions (TWL) patterns in patients attending gastroenterology and respiratory clinics in a tertiary health facility: a comprehensive analytical study.
FUNDER: Self-funded
BRIEF SUMMARY: This study delves into the intricate patterns of Tooth Wear Lesions (TWL) among individuals attending Gastroenterology and Respiratory Clinics. The study aims to systematically analyze and document the specific manifestations of TWL in this unique patient population. Through a comprehensive intra-oral examination and data analysis, the research endeavors to uncover subtle patterns and potential correlations between tooth wear and underlying gastroenterological or respiratory conditions. The findings from this study hold significant promise for advancing our understanding of oral health implications in these patient groups, potentially informing tailored preventive and therapeutic interventions. The research aligns with a broader objective of enhancing interdisciplinary healthcare by bridging oral health considerations with gastroenterological and respiratory care, ultimately contributing to more holistic and patient-centric medical practices.
