Master’s Degree Awarded to Ms. Angham Ali Abdulaziz Abu Lehoum in Orthodontics
Ms. Angham Ali Abdulaziz Abu Lehoum was awarded a Master’s Degree in Orthodontics for her thesis titled: Evaluation of Posterior Available Space in Both Arches Relative to Various Skeletal Patterns in A Group of Yemeni Adults Using Cone-Beam Computed Tomography, which was submitted to the Faculty of Dentistry – Sana’a University. The MA defense was held on Tuesday, November 25, 2025.
The MA Viva-voce Committee, which was formed based on a resolution issued by the Graduate Studies and Scientific Research Council, consisted of the following:
| # | Committee Members | Designation | Position |
| 1 | Prof. Naila Mohammed Ali Al-Mujahid | Internal Examiner | Chair |
| 2 | Prof. Hussein Mohammed Shujaa Al-Deen | Main Supervisor | Member |
| 3 | Assoc. Prof. Khaled Ahmed Ali Al-Dharee | External Examiner | Member |
The study aimed to:
- Evaluate the posterior available space in both the maxillary and mandibular arches and examine its relationship to different skeletal patterns.
- Provide accurate data to enhance orthodontic diagnosis, treatment planning, and preventive dental care for Yemeni adults using CBCT technology.
The study employed cone-beam computed tomography (CBCT) to obtain precise and true measurements of posterior available space. It analyzed the relationship between available arch space and skeletal patterns to determine the influence of morphological factors on orthodontic treatment decisions. It also employed a detailed research methodology, including sample selection, measurement tools, and statistical analysis techniques.
The study yielded a number of key findings summarized as follows:
- CBCT demonstrated high accuracy in measuring posterior available space compared to conventional measurement methods.
- Clear differences in posterior available space were identified among the various skeletal patterns in Yemeni adults.
- The findings support improved diagnostic accuracy and more effective orthodontic and preventive treatment planning.
In light of these findings, the researcher recommended:
- Expanding future studies to include larger samples and multiple age groups.
- Strengthening the use of advanced imaging techniques in orthodontic diagnostic evaluation.
- Emphasizing the importance of training dental practitioners in CBCT applications to ensure measurement accuracy and effective treatment planning.
The defense session was attended by a number of academics, researchers, students, colleagues, and the researcher’s family.
