“…Because slight maxillary incisors proclination is the norm, less retraction of maxillary incisors is required, and keeping the soft tissue paradigm in mind (increased soft tissue chin thickness), we can leave mandibular incisors more uprighted in Maratha males. Proclined maxillary incisors were also seen in Mahabubnagar population,[ 4 ] Maratha population,[ 11 ] and Andhra Pradesh population,[ 12 ] whereas in central Indian population,[ 5 ] the results were similar to the Caucasian population[ 10 ] but contrary to the South Indian ethnic population.

“…What is normal for one specific ethnic group may not be for another, which has been reported by many other authors for different populations. [ 4 5 6 7 11 12 13 14 15 16 18 20 21 22 23 24 ] Single sets of norms cannot be applied to each and every racial and ethnic group, and thus it is necessary to study the soft tissue standards of a particular community and consider those norms when formulating an orthodontic and orthognathic treatment plan for the particular racial and ethnic patients.…”

Aim:The aim of this article is to evaluate the mean cephalometric values for Arnett's soft tissue analysis in the Maratha ethnic (Indian) population.Materials and Methods:Lateral cephalograms of 60 patients (30 males and 30 females) aged 18–26 years were obtained with the patients in the Natural Head Position (NHP), with teeth in maximum intercuspation and lips in the rest position. Moreover, hand tracings were also done. The statistical analysis was performed with the help of a statistical software, the Statistical Package for the Social Sciences version 16, and Microsoft word and Excel (Microsoft office 2007) were used to generate the analytical data.Results:Statistical significance was tested atP level (1% and 5% level of significance). Statistical analysis using student's unpaired t-test were performed. Various cephalometric values for the Maratha ethnic (Indian) population differed from Caucasian cephalometric values such as nasolabial inclination, incisor proclination, and exposure, which may affect the outcome of the orthodontic and orthognathic treatment.Conclusion:Marathas have more proclined maxillary incisors, less prominent chin, less facial length, acute nasolabial angle, and all soft tissue thickness are greater in Marathas except lower lip thickness (in Maratha males and females) and upper lip angle (in Maratha males) than those of the Caucasian population. It is a fact that all different ethnic races have different facial characters. The variability of the soft tissue integument in people with different ethnic origin makes it necessary to study the soft tissue standards of a particular community and consider those norms when planning an orthodontic and orthognathic treatment for particular racial and ethnic patients.

Objective: The purpose of this study was to investigate maxillofacial morphology using CBCT with the ultimate goal of finding whether differences existed in a two suggested subtypes of nonsyndromic bilateral cleft lip and palate (BCLP) patients.Design: This retrospective study included CBCT data of 22 BCLP patients with mean age of 9.6 years. The patients were divided initially according to premaxillary characteristics into two groups and this classification was further confirmed by measurement of sella-nasion-point A angle (SNA), Group (P): This represent BCLP characterized by well-developed (P) prominent pre-maxilla and SNA >80±2, Group(R): This represent BCLP characterized by ill-developed (R) rudimentary pre-maxilla and SNA < 80±2. The relation between maxilla and mandible measured by point A-nasion-B point angle (ANB), angle of septal deviation (ASD) and anterior upper facial height (AUFH) were assessed using On-demand 3D software and was compared among the two groups.Results: Patients within group P showed significantly higher ANB (P value ≤ 0.001). Patients within group R showed significantly higher ASD angle (P value ≤ 0.05), while AUFH showed insignificant difference between the two groups (P value ≥ 0.05). Conclusions:Maxillofacial morphology measurements assessed in this study support that difference exist between the two investigated subtypes of non-syndromic BCLP.

“…Accordingly, each distance and angles have their own normative indexes, which according to the authors as a whole form a harmonious tooth-jaw system. However, as has already been proven in the works on other methods of cephalometric analysis of lateral teleroentgenograms, these indices are different for persons of different ethnic, gender and age affiliations [7,10,11,15].…”

It is proved that in the analysis of lateral teleroentgenograms according to different methods distances and angles have their normative indices which differ for persons of different ethnic, gender and age belongings. Therefore, for a full use in the orthodontics R.M. Ricketts method, similar studies are needed in Ukraine. The purpose of the work -in boys and girls with normal occlusion close to the orthognathic bite and harmonious face construct and analyze the regression models of teleroentgenographic indicators used in the method of R. M. Ricketts. Primary lateral teleroentgenograms of 38 young men (aged 17-21 years) and 55 young women (aged from 16 to 20 years) with normal occlusion close to orthognathic bite and harmonic face, obtained from the Veraviewepocs 3D device, Morita (Japan), taken from the bank data of research center of National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of R. M. Ricketts. All indicators were divided into three groups: 1 -metric characteristics of the skull, which usually do not change during surgical and orthodontic treatment; 2 -tooth-jaw indicators, the definition of which most often guided by performing orthodontic manipulations of patients in children and adolescents, as well as those with already formed bone skeleton when orthodontic surgery can change the width, length, angles and position of the bones of the upper and lower jaws; 3 -indicators that characterize the position of each individual tooth relative to each other, to the bony cranial structures and face profile. The regression models of individual teleroentgenographic indicators used in the R.M. Ricketts methodology are constructed using the "Statistica 6.0" licensing package. Constructed all 2 reliable models of the indicators included in the second group (distance Go-CF and Xi-Pm), depending on the indicators of the first group (in young men R 2 = 0.884 and 0.928, and in young women -0.735 and 0.719); as well as in young men, 7 out of 8 possible reliable models (R 2 = 0.568 to 0.887) of the indicators included in the third group (the magnitude of the distances 6u-6l, Overjet, Overbite, 6u-PTV, 1l-APog, 1u-APog and Xi-OcP ) depending on the indicators of the first and second groups; and only 5 models for young women (6u-PTV, 1l-APog, 1u-APog and Xi-OcP distances, and the magnitude of the Max1-APog angle). In the analysis of entering into the regression models of the relevant predictors, it was found that in young men, among the teleroentgenographic indicators of the first group included in the two models of the second group, is the distance P-PTV, and in young women the front length of the base of the skull N-CC and the back of the skull base Ar-Pt It was also found that among young men among the teleroentgenographic indicators of the first and second groups, which were included in the models of the third group, the most frequent is the value of the distance B-Pog (11.1%); while in young women -distance B-Pog (15.6%) and an angle DC-X...
