Background/objectives: Parents/caregivers' reports are valuable because they frequently play a crucial role in making decisions concerning a child's health, and their perspectives can significantly impact treatment choices. Furthermore, negative effects of oral health issues extend beyond just the adolescent patient, having an impact on family life. The aim of this study is to explore the perception of parents/caregivers regarding their children's oral-health-related quality of life (OHRQoL) and how the OHRQoL of adolescents impacts their family life.

A Novel Virtual Planned-Orthodontic-Surgical Approach for Proportional Condylectomy in Condylar Hyperplasia.

Condylectomy is a delicate and intricate procedure commonly employed in the management of temporomandibular joint (TMJ) disorders, osteochondromas, condylar hyperplasia, hemimandibular hyperplasia, and other pathologies affecting the condylar region. The advent of surgical cutting guides has introduced a new dimension to condylectomy procedures as they enable surgeons to plan and execute precise cuts with a heightened level of accuracy. In the literature already exists cases of cutting guide-based condylectomy, but they only depend on the mere mirroring procedure in virtual planning, which has accuracy limitations because it does not consider asymmetry of peri-condylar structures at the level of the ramus, body, and mandibular angle.
