The Characteristic of Transverse Dental Arch Relationship Study in Unilateral Cleft and Palate versus Noncleft in Thai Northeastern Population

In comparison to noncleft individuals, the majority of UCLP cases exhibited class II angles with negative overjet. A significantly smaller transverse arch width was observed in the maxilla of UCLP patients, with no significant variances noted in the mandible. Analysis using the MHB index indicated greater total arch constriction in UCLP cases, particularly in the anterior tooth region. Furthermore, the severity of these findings was observed to escalate with age.
