ABSTRACT Introduction: McNamara’s Jr. cephalometric analysis is a tool to diagnose dental and skeletal discrepancies and is widely used, guiding diagnosis for surgical procedures to be performed or for the use of functional devices. Few studies have shown that different ethnic groups have different cephalometric patterns. Thus, single characteristics should be respected to support the diagnosis and to help the treatment plan for different ethnic groups and their different patterns of miscegenation. Objective: Obtain normal values for McNamara’s cephalometric analysis for adolescent Japanese-Brazilian descents with normal occlusion, as well as to compare this sample with similar samples of White-Brazilian and Japanese. Methods: Lateral headfilms from 40 White-Brazilian, 33 Japanese and 32 Japanese-Brazilian descents were selected. The three groups were composed by individuals with normal occlusion, well-balanced profiles and were separated by sex. The data were statistically analyzed with ANOVA, t-test, ANCOVA and MANCOVA tests. Results: White-Brazilian males had significantly greater nasolabial angle than Japanese males. Japanese-Brazilian displayed an intermediate value between White-Brazilian and Japanese. Conclusion: White-Brazilian, Japanese and Japanese-Brazilian present different cephalometric characteristics of McNamara analysis. Japanese males have a significantly more acute nasolabial angle than White-Brazilian subjects.

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.

Objective:  To find out the differences in craniofacial pattern between Class lll malocclusion and normal occlusion in Nepalese population. Materials and Methods: Lateral cephalogram of 30 patients with Class lll malocclusion (11 male and 19 female; mean age, 17.27 ±3.88 years) and 30 patients with normal occlusion (15 males and 15 females; mean age: 19.03 ± 4.94 years) were analyzed for various linear and angular measurements. The variables between the two groups were compared using independent  t - test. Results: The base angle N-S-Ar was significantly smaller ( < 0.05) in Class lll group. The relative position of the maxilla in sagittal relation as indicated by angle of convexity (N-A-Pog) and A to N perpendicular was significantly retrusive in Class lll group ( < 0.05). The length of the maxilla was significantly reduced in Class lll group ( <0.01). The relative sagittal position of the mandible was significant protrusive in Class lll group as indicated by SNB (P< 0.01), facial angle (FH to N Pog) ( <0.05) and N perpendicular to Pog ( <0.001). The upper incisors were proclined and positioned anteriorly ( <0.01) in Class lll group while the lower incisors were retroclined ( <0.05). The upper lip in Class lll was retrusive ( < 0.05) relative to Ricketts esthetic plane and the nasolabial angle was significantly decreased in Class lll groups (  < 0.01). Conclusion: There are significant differences in craniofacial pattern in Class lll Nepalese population as compared to normal Nepalese population.

INTRODUCTION: This study aims to determine the shape and dimension of dental arches from a lingual perspective, and determine shape and size of a straight archwire used for lingual Orthodontics. METHODS: The study sample comprised 70 Caucasian Brazilian individuals with normal occlusion and at least four of Andrew's six keys. Maxillary and mandibular dental casts were digitized (3D) and the images were analyzed by Delcam Power SHAPET 2010 software. Landmarks on the lingual surface of teeth were selected and 14 measurements were calculated to determine the shape and size of dental arches. RESULTS: Shapiro-Wilk test determined small arch shape by means of 25th percentile (P25%) - an average percentile for the medium arch; and a large one determined by means of 75th percentile (P75%). T-test revealed differences between males and females in the size of 12 dental arches. CONCLUSION: The straight-wire arch shape used in the lingual straight wire technique is a parabolic-shaped arch, slightly flattened on its anterior portion. Due to similarity among dental arch sizes shown by males and females, a more simplified diagram chart was designed.

A Prospective Study

The present study aimed to evaluate the occurrence of significant changes in systemic blood pressure (SBP) during surgical-dental procedures. A prospective study was performed with a sample of 135 randomly selected individuals who underwent surgical procedures at the Bucomaxillofacial Surgery Clinic of the Dentistry School of the ESFA (ES) between the second half of 2017 and April 2018. After consent, sociodemographic, lifestyle data, weight and height were obtained through a questionnaire, weighing and measurement, respectively. BP measurements were performed at three moments: preoperative (BP1), intraoperative (BP2) and postoperative (BP3) using a mercury column sphygmomanometer and stethoscope. Values ​​<120/80 mmHg were used as normal values. When BP1 and BP2 were compared, 63.0% remained within normal values ​​and 22.2% reached the stage of hypertension. In the comparison of BP1 and BP3, 66.7% remained normal, and only 7.4% reached the stage of hypertension. When BP2 and BP3 were compared, 53.6% remained within the normality stage and 12.2% reached the stage of hypertension. It was concluded that there were variations in blood pressure, being the largest variation found in BP2, and can be attributed to the stress caused by the surgical act, since no statistically significant connections were found between the changes in blood pressure and the anesthetics used in the research.

Three-dimensional (3D) computer-aided simulation has revolutionized orthognathic surgery treatment, but scarce 3D cephalometric norms have been defined to date. The purposes of this study were to (1) establish a normative database of 3D Burstone cephalometric measurements for adult male and female Chinese in Taiwan, (2) compare this 3D norm dataset with the two-dimensional (2D) Burstone norms from Caucasian and Singaporean Chinese populations, and (3) apply these 3D norms to assess the outcome of a computer-aided simulation of orthognathic surgery. Three-dimensional Burstone cephalometric analysis was performed on 3D digital craniofacial image models generated from cone-beam computed tomography datasets of 60 adult Taiwanese Chinese individuals with normal occlusion and balanced facial profile. Three-dimensional Burstone analysis was performed on 3D image datasets from patients with skeletal Class III pattern (n = 30) with prior computer-aided simulation. Three-dimensional Burstone cephalometric measurements showed that Taiwanese Chinese males had significantly (p < 0.05) larger anterior and posterior facial heights, maxillary length, and mandibular ramus height than females, with no significant (p > 0.05) difference for facial soft-tissue parameters. The 3D norm dataset revealed Taiwanese Chinese-specific facial characteristics, with Taiwanese presenting (p < 0.05) a more convex profile, protrusive maxillary apical bases, protruding mandible, protruding upper and lower lips, and a shorter maxillary length and lower facial height than Caucasians. Taiwanese had significantly (p < 0.05) larger maxillary projection, vertical height ratio, lower face throat angle, nasolabial angle, and upper lip protrusion than Singaporean Chinese. No significant (p > 0.05) difference was observed between 3D norms and computer-aided simulation-derived 3D patient images for horizontal skeletal, vertical skeletal, and dental measurements, with the exception of two dental parameters (p < 0.05). This study contributes to literature by providing gender- and ethnic-specific 3D Burstone cephalometric norms, which can assist in the multidisciplinary-based delivery of orthodontic surgical care for Taiwanese Chinese individuals worldwide, including orthodontic management, computer-assisted simulation, and outcome assessment.

PurposeThis qualitative study was to understand the factors affecting successful adoptive breastfeeding among women who underwent induced lactation process.Design/methodology/approachThis study conducted in-depth interviews among induced lactation women in five states based on five regions [South (Johor), Central (Selangor), North (Penang), East (Kelantan) and East Malaysia (Sabah)]. The interviews have been consented, audio-recorded then transcribed verbatim, followed by identification of emerging themes.FindingsData saturation was achieved after interviewing a total of 23 induced lactation women. There were six main themes that emerged to describe factors affecting successful induced lactation process: (1) support and encouragement, (2) diet supplementation, (3) breastfeeding devices support, (4) incorporating treatment plan in the daily schedule, (5) high determination and pleasant attitude and (6) being informed on induced lactation process.Research limitations/implicationsThere can be recall bias among the respondents since the information was collected retrospectively, one to two years after the induced lactation practice completed. Due to that, we cannot rule out recall bias in the responses given in the interviews. In this study, induced lactation women barely were ethnic Malay Muslims. Thus, comparisons to other ethnic groups were not possible. This was due to the difficulty to get participation from induced lactation mother of other ethnic groups in the study. Even though the success is demonstrated, a significant limitation is that the ratio between Muslims and non-Muslims cannot be performed for the reason that the respondents only consists of Muslims alone.Originality/valueThe benefits of breastfeeding by an adoptive woman are numerous for both the mother and baby. There are multifactors involved in successful induced lactation process. After experiencing induced lactation, all respondents agreed that it has prepared them to be real mothers and breastfeeding is a pleasurable experience. All respondents corresponded to breastfeeding have a positive influence in the aspect of affection and touch. A mother who feels confident in her ability to lactate and is reassured by those around her will be most likely to feel successful in this great attempt.

ABSTRACT Objective:  To evaluate the overbite correction of fixed palatal crib (FPC) and bonded lingual spur (BLS) in the early treatment of anterior open bite (AOB) in mixed dentition (primary outcome) as well as its influence on dental and skeletal cephalometric measurements (secondary outcome). Materials and Methods:  The selected patients had AOB and a mean age of 8.23 years. They were divided into the following three groups by casting lots: control (n  =  13), palatal crib (n  =  13), and spur (n  =  13). Data from the lateral teleradiography was obtained at the beginning, at 6 months, and after 1 year. The cephalometric analysis was performed by Cef-X program, recording the values of SNA, SNB, ANB, SnG oGn, 1.PP, IMPA, nasolabial angle, overbite, and overjet. Intergroup and intragroup comparisons were obtained via one-way analysis of variance. Results:  The degree of AOB was similar at baseline (P &gt; .05). At 6 months and then after 1 year all groups showed improvement in the overbite. However, only the crib and spur groups showed positive overbite. No cephalometric measurements changed significantly over the period analyzed. Conclusions:  We conclude that the FPC and BLS are simple and effective for the treatment of anterior open bite, with the advantage given to the FPC.

Abstract Objective: To analyze anteroposterior soft tissue facial parameters for a sample of white Brazilian adults and to compare these measurements with the values proposed for white North American adults. Materials and Methods: Facial profile photographs were taken of 59 white Brazilians (30 men and 29 women) with normal occlusions and balanced faces with ages ranging from 18 to 30 years. The independent Student's t-test (P &lt; .05) was used to compare the soft tissue parameters of the Brazilians with those of the North Americans. Results: White Brazilian women presented a less protruded face compared with white American women except for the glabella region. White Brazilian women showed a smaller nasal projection, less protruded upper and lower lips, a more obtuse nasolabial angle, and a smaller projection of the B′ point and chin than white American women. Conversely, the two male groups demonstrated less evident soft tissue profile differences, with the exception of the nose projection, which was smaller in white Brazilian men than in white American men. Conclusions: A universal standard of facial esthetic is not applicable to diverse white populations. Differences regarding the soft tissue profile features were found between white Brazilians and white Americans. These differences should be considered in the orthodontic/orthognathic surgery diagnosis and treatment plan for white Brazilians together with the patient's individual opinion and perception of beauty.

This study has attempted to examine perceived discrimination difference between the Manjo clan and non-manjos in Kaffa zone that is located in the south west of Ethiopia. A total of 298 individuals who belong to the manjo and non-manjo groups were randomly selected and involved in the study. The researchers utilized an independent sample t-test to compare the level of perceived discrimination between the Manjo and the non-Manjos ethnic groups. Seen segregation is the changeability of thought coming because of behavior of isolating group of people that radiates from predisposition and partiality. As revealed in the study, there is a significant mean variation among manjos and non-manjos with respect to perceiving discrimination. The thought of being discriminated showed significant mean difference between the group of manjos and non-manjos. The finding implies the need for further research and social work intervention to minimize the action and sense of being discriminated as this relates to the overall psychosocial wellbeing of persons in a given community.
