Master’s Degree Awarded to Ms. Wafaa Mohammed Al-Sherrai in Orthodontics
Ms. Wafaa Mohammed Ghaleb Al-Sherrai was awarded a Master’s Degree in Orthodontics for her thesis titled: Skeletal and Dentoalveolar Dimensions in Cases of Unilateral Palatally Impacted Canines: A Cone-Beam Computed Tomography Study, which was submitted to the Department of Orthodontics, Faculty of Dentistry – Sana’a University. The MA defense was held on Tuesday, January 20, 2026.
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:

3 Prof. Khaled Ahmed Al-Dara’i External Examiner Member
The study aimed to conduct a three-dimensional comparison of skeletal and dentoalveolar dimensions in patients with unilateral palatal canine impaction, compare the impacted and non-impacted sides, and assess differences according to gender, presence or absence of the deciduous canine, and side of impaction.
The study yielded a number of key findings summarized as follows:
Unilateral palatal impaction of the maxillary canine was associated with significant asymmetry in skeletal and dentoalveolar dimensions.
The impacted side showed smaller alveolar width at the premolar region, smaller canine dimensions, and shorter quadrant length.
Significant differences were observed in the lateral inclination of incisors and canines between the impacted and non-impacted sides.
Retention of the deciduous canine was associated with increased alveolar and dental width at the premolar region.
In light of these findings, the researcher recommended the following:
Using cone-beam computed tomography (CBCT) for early diagnosis of unilateral palatal impaction of the maxillary canine.
Assessing alveolar width at the premolar level and early intervention with appropriate expansion.
Careful treatment planning to avoid root resorption and to prevent premature extraction of the deciduous canine without adequate expansion.
Close monitoring of the eruption path of the canine, especially in female patients.
The defense session was attended by a number of academics, researchers, students, colleagues, and the researcher’s family.
