Abstract: The primary aim of this study is to compare, the cephalometric hard tissue profile values and analysis between Tamil and Caucasian population. The study also aims to create a better understanding in the facial proportions of Tamil Nadu population and to have better diagnosis and treatment planning for orthognathic surgery for Tamil population in Tamil Nadu.

“…Altemus (1960) acknowledged that it is all because individual of different races and ethnic have contrast in skeletal, soft-tissue, and dental. Alcalde et al (1998), Craven (1958), and Hajighadimi et al (1981), they all claimed that cephalometric norms very clear for each ethnic groups according to the previous, cephalometric norms of Caucasians have been noted that there are a big difference according to those of Indians (Atit et al, 2013), Tamils Nachiappan et al, 2015), Arabs (Hassan, 2006), Nepalese (Sharma, 2011), Turkish (Kilic et al, 2010), Japanese (Ioi et al, 2007), Chinese (Gu et al, 2011), Korean (Hwang et al, 2002), Pakistani (Khan et al, 2013), and African (Fadeju et al, 2013) populations. These distinctions ought to be considered in orthodontic finding and treatment planning just as in orthognathic surgery.…”

Ethical group might have differential skeletal forms, thus cephalometric analysis and orthodontic material have been developed for specific ethnic groups which might be different for Kurdish Ethics.Objectives: This study is to determine the cephalometric norms of an Erbil Kurdish population according to Steiner analysis, who attend to Tishk Hospital/Diagnosis Department Materials and Methods: In this cross-sectional study, 48 lateral cephalograms of adult orthodontic subjects between 20 and 29 years with normal occlusion, and with no previous orthodontic treatment were evaluated. Lateral cephalograms were traced and analyzed based on Steiner’s cephalometric parameters. Data were analyzed using SPSS. Differences between Erbil Kurdish and Steiner’s norms were analyzed using one-sample t-test (P < 0.05). Results: The SNA, ML-NSL (Mandibular Line to NS line), U1-NA (both angular and linear measurements), interincisal angle, L1-NB (angular only), Pog-NB, L1-Pog//NB, Ls-SL, and Li-SL values were significantly different between the Erbil Kurdish population and Steiner’s norms (P < 0.05). No significant differences existed in Occl-SN (occlusal plane to SN) and L1-Nb (linear only), SNB, and ANB between the Erbil Kurdish population and the Steiner’s norms (P > 0.05). Conclusions: Cephalometric norms for Erbil Kurdish adults are different from those of Steiner’s norms. The norms obtained in our study can be used for orthodontic treatments and orthognathic surgeries in Erbil Kurdish population.

Aim: Variability exists in the ethnic groups that are separated by culture and geographic boundaries. The aim of this study was to evaluate hard tissue profile of well-balanced and clinically acceptable Maharashtrian population. Furthermore, compare the cephalometric values of Maharashtrian population with the established norms of Caucasians. Materials and Methods: Lateral cephalogram of 100 patients (50 males and 50 females) in the age group of 20–30 years, were taken in the natural head position. Cephalometric analysis was performed on them and compared to the values of the Caucasians. Results: Statically significant differences were obtained in the between the Maharashtrian population and the Caucasians. Maharashtrian males have a straighter profile, reduced vertical height, and reduced mandibular divergence compared to Caucasian males. Maharashtrian females have a convex profile, reduced vertical height and reduced mandibular divergence. Conclusion: Since significant differences were found in the Maharashtrian population compared to the Caucasians. These values should be taken into consideration when assessing the Maharashtrian patient with facial deformity to obtain optimal results.

This study is intended to review the cephalometric data pertaining to the diverse Indian populace through a systematic literature survey. To conduct a systematic review of literature, an electronic search was done on Medline, Embase, and Central databases. The available data were categorized based on the existing five geographic locations of the country (north, south, east, west, and central India) and analyzed. The following inclusion criteria were considered: (1) studies depicting the cephalometric data of any ethnic group identified as belonging to India, (2) studies originating from the Indian subcontinent, (3) studies which included data of subjects’ gender separately, (4) studies which compared the cephalometric data of the Indian population with the that of the Caucasians using Burstone and Legan analysis alone, and (5) articles in English language only. The following exclusion criteria were considered: (1) studies conducted on participants with developmental craniofacial anomalies, post traumatic facial deformities or with a history of previous orthognathic surgery, (2) studies which used analysis other than Burstone and Legan for obtaining the data, (3) editorials, commentaries, case reports, systematic reviews, meta-analyses, and articles not available in English language. Seventeen articles met the inclusion criteria. The Indian population showed greater cranial base dimensions than the Caucasians. In the horizontal dimension, the Indian population exhibited a more convex profile with prognathic maxilla, mandible, and chin along with more protrusive upper and lower incisors. However, in the vertical dimension, they exhibited a decreased middle third facial height as well as a decreased ramal and corpus length of the mandible when compared with the Caucasians. The posterior maxillary height and the posterior facial divergence were relatively less in the Indian population when compared with the Caucasians. Sexual dimorphism was noted among the Indian population with regard to a few vertical skeletal parameters which were significantly greater in males than in females. It was observed that the data pertaining to the cephalometric norms on Indian populace in comparison with the Caucasian race are scanty. Compared to the other geographic locations of India, very less literature is available pertaining to the cephalometric data of the Eastern Indian population. It was observed that very less data are available pertaining to the cephalometric norms for the Indian population considering the ethnic, racial, and geographic diversity. The low sample size, studies being restricted to a specific race, or the lack of comparative studies largely impacts the reliability of the available cephalometric data on the Indian population. Considering the fact that the prevalence of dentofacial deformities in India is high, there is a huge ambit for corrective jaw surgery. Hence, it is essential to compile cephalometric data for the Indian populace to establish ethnic and racial-based cephalometric norms.
