Soft tissue cephalometric analysis applied to regional Indian population

Area of Science:

• Orthodontics
• Cephalometrics
• Facial aesthetics

Background:

• Soft tissue analysis is crucial for orthodontic and orthognathic surgery treatment planning.
• Existing cephalometric norms exhibit significant population variations.
• Regional normative data is essential due to diverse facial aesthetics.

Purpose of the Study:

• To compare standard soft tissue cephalometric analysis (STCA) norms with those derived for the Western Uttar Pradesh population in India.
• To identify population-specific variations in soft tissue facial parameters.

Main Methods:

• Lateral cephalograms of 33 healthy individuals (16 males, 17 females) were analyzed.
• Standard soft tissue cephalometric analysis (STCA) was employed.
• Student's t-test compared study population means with established STCA norms.

Main Results:

• Females exhibited steeper maxillary occlusal planes, more proclined mandibular incisors, and less protrusive lips compared to standard norms.
• Both males and females showed reduced facial lengths and less prominent midface and mandibular structures.
• A more convex facial profile was observed in the study population compared to White population norms.

Conclusions:

• Significant differences were identified in key STCA parameters for the Western Uttar Pradesh population.
• Established STCA norms require regional adaptation for accurate orthodontic and orthognathic treatment planning.
• This study underscores the importance of population-specific cephalometric data.
