“…In the present study it was seen that a statistically significant correlation existed between face form and arch form (p<0.001). This was similar to the studies conducted by Nayar et al 22 and Sellen et al 23 However, no correlation was found among rugae pattern with the face form and arch form.…”

Purpose: To evaluate the correlation between the palatal rugae pattern, face form and arch form among Indian population at Moradabad, India. Materials and Methods: Alginate impressions of maxillary arch was made and cast was poured immediately with type III dental stone. A sharp graphite pencil was used for marking outline of the rugae on the cast. A digital caliper was employed for measurement of length of palatal rugae. Palatal rugae were analysed in accordance with Thomas and Kotze classification. Arch form of these models was determined with using 3M Unite template. For assessment of the face form, the subjects were seated in an upright position on the operator chair and the camera was stabilized on a tripod. Then photographs of the frontal profile were taken. These photographs were used for the analysis of the face form. The data was subjected to one way analysis of variance test and Post Hoc test. Results: The average number of primary rugae (10.76%) were found to be more predominant than secondary (2.12%) and fragmentary rugae (1.54%). The most predominant shape of palatal rugae were curved (42.19%) followed by wavy (32.71%), straight (17.37%) and circular (0.92%). Based on the direction of the rugae, forward rugae (54.27%) were found more common followed by backward rugae (37.26%) and perpendicular rugae (0.55%). Base on the unification of rugae pattern, diverging rugae (4.55%) were found to be more common than the converging rugae (1.57%). The most common face form was ovoid (72.4) % followed by tapered (24.4%) and square (3.2%). The most prevalent arch form was ovoid (62.2%) seen followed by the tapered (26.0%) and square (4.8%) arch form. It was found that there was significant correlation between the face form and arch form among the study subjects (p<0.001). However, no correlation was found between the rugae pattern, face form and arch form (p>0.05). In term of arch form and face form, ovoid was the most common followed by tapered and square. Conclusion:Within the limitations of this study, it was concluded that there was significant correlation between the face form and arch form among the study subjects. However, no correlation was found between the rugae pattern with face form and arch form.

“…The mean interpremolar, intermolar dental and interpremolar, intermolar alveolar arch width in both maxillary and mandibular arches were found to be highest in hypodivergent patients and least in hyperdivergent patients, which was not found to be statistically significant. This is in conformance with the researches done by Uysal et al (2005), 15 Khera et al (2012), 8 Ribeiro et al (2012), 19 Grippaudo et al (2013), 20 Bhutta et al (2013), 1 Shahroudi and Etezadi (2013), 21 Prasad et al (2013), 22 Bălan et al (2014), 23 Nayer et al (2015), 24 Traldi et al (2015), 25 Gupta and Makhija (2016), 26 Perez et al (2016), 27 Aditi et al (2017), 28 and Nagrajmurthy (2017). 29 However, the data from this study presented an antithetical fashion between SN-MP angle and dental arch widths, the relationship was less strong, which showed that the SN-MP angle might not be only one of the contributing factors.…”

Introduction The facial growth pattern differs from individual to individual, and the variations in it are quite high. The assessment of relationship of dental arch dimensions with the facial growth pattern is essential for proper diagnosis and treatment planning. Aim The purpose of this study was to evaluate and compare the dental and alveolar arch widths in patients with varying facial growth patterns in Distt. Solan population. Materials and Methods Pretreatment lateral cephalograms and dental study models of 45 patients with age group between 16 and 30 years were included in the study. Patients were divided into three groups: group I (normodivergent), group II (hypodivergent), and group III (hyperdivergent) on the basis of y-axis, Jarabak ratio, and SN-MP (Sella-Nasion–mandibular plane) angle. Interpremolar and intermolar dental and alveolar arch widths were measured and compared for all the three groups. Results The results showed that the dental and alveolar arch widths were increased in hypodivergent patients and decreased in hyperdivergent patients, which was not statistically significant. Conclusion It was concluded that the dental and alveolar arch dimensions increased as the facial pattern became horizontal.

“…A team of Indian researchers linked face shape and dental arch in a survey of 40 people aged 20-25. Statistical analysis revealed that 54.6 % of persons with a mean facial type had an egg-shaped dental arch while 63.6 % of persons with a narrow facial type had a square arc [19].…”

Providing maximum individual orthodontic care to the patient is impossible without the use of modern instrumental methods of research and considering odontometric and cephalometric characteristics of representatives of relevant populations of different sex and age. The purpose of the study is to develop and analyze regression models of computed tomography sizes necessary to construct the correct form of dental arches in young women with a very wide face, depending on the characteristics of odonto- and cephalometric indicators. Primary computed tomographic indices of tooth size and cephalometric parameters of 50 young women with normal occlusion close to orthognathic occlusion were obtained from the data bank of the scientific-research center of National Pirogov Memorial Medical University, Vinnytsya. Face type was determined using the Garson morphological index. The following distribution is established: with a very wide face – 21, with a wide face – 20, with a medium face – 6, with a narrow face – 3, with a very narrow face – 0. Therefore, only young women with a wide and very wide face were selected for further modeling. The development of regression models of linear dimensions necessary for the construction of the correct form of dental arches, depending on the features of odonto- and cephalometric indicators in young women with very wide faces, was carried out in a licensed statistical package “Statistica 6.0”. It is established that young women with a very wide type of face with normal occlusion have built all 18 possible reliable models (with a coefficient of determination from 0.863 to 0.962) of linear computed tomography sizes used to construct the correct form of dental arches of the upper and lower jaws in depending on the features of odontometric and cephalometric indicators. Built models in young women with a very wide face type included more often odontometric (73.0 %) than cephalometric (27.0 %) data. Among the odontometric indicators, the most frequently included models are: width of crowns of teeth in mesio-distal direction (20.7 %); width of the teeth at the level of the anatomical neck in the mesio-distal direction (14.4 %) and width of the crowns of the teeth in the vestibulo-oral direction (10.8 %); and among the cephalometric indicators – the greatest length of the head (3.6 %); average width of face and height of lower lip (2.7 % each). Thus, in young women with a very wide type of face with normal occlusion close to orthognathic occlusion, all 18 possible reliable regression models of reproduction of the individual characteristics of the dental arches of the upper and lower jaws depending on the odonto- and cephalometric parameters were developed and analyzed.
