A cross-sectional study to correlate nasal profile and chin position with cephalometric lip profile.

Department of Surgery, Section of Dentistry, The Aga Khan University and Hospital, Karachi, Pakistan.
Objective: To determine the effect of the nose and chin on the cephalometric lip profile.
Methods And Material: The pre-treatment lateral cephalograms of 177 adult patients with no history of orthodontic treatment were manually traced. The sample size was divided into three vertical and horizontal groups using angle ANB and MMA to assess the difference in nose and chin forms.

Background: In clinical orthodontic practice, to evaluate aesthetics in dentistry, lateral cephalometry and lateral photometry are used to measure and assess craniofacial morphology. In contrast to cephalometry, photometry has no radiation hazard and is less expensive. There has been a paradigm shift in contemporary orthodontics that now emphasizes soft tissue aesthetics, rather than depending entirely on hard tissue evaluation from lateral cephalometry.

Department of Orthodontics, Institute of Oral Health Science, Ajou University School of Medicine, Suwon, South Korea.
Objectives: This study aimed to propose guidelines for the indications of non-extraction, extraction camouflage treatment, and orthognathic surgery by comparing the degree of soft tissue improvement effects. This comparison focused on changes in CKHA, a soft tissue indicator corresponding to the major hard tissue indicator, ANB.
Materials And Methods: Sixty-six patients, 25 males and 41 females, aged between 18 and 50 years and diagnosed with skeletal Class III malocclusion (ANB < 0°), were enrolled in the study.

The study aimed to compare cephalometric hard tissue profile values and analysis between Bengali and Caucasian populations. The study included 100 individuals (50 males, 50 females) aged 18-35. Subjects having class I molar occlusions and well-balanced facial profiles were included in the study.

Orthodontics, Armed Forces Institute of Dentistry, Rawalpindi, PAK.
Background: Soft tissue analysis can be used to assess anatomical features but may or may not accurately correlate with underlying hard tissue morphology, leading to an incorrect perception of malocclusion.
Objective: This study aimed to assess the reliability of different soft tissue reference lines used to evaluate anteroposterior lip position and the position of incisors and malocclusion and compare it with those assessed via hard tissue angles (LSMx and LIMd) and determine if they are true indicators of underlying protrusion of incisors and malocclusion.
Method: A total of 120 pre-treatment lateral cephalometric radiographs were selected where patients were 18-30 years old, diagnosed as Skeletal Class I, II (Division 1 and 2), and III malocclusion.
