Teeth are known as organs made up of the hardest mineral tissue that is resistant to decay and physical, thermal, mechanical, chemical or biological damage. Tooth crown dimensions are reasonably accurate predictors of genders especially to young individuals whose secondary skeletal characteristics are yet developed. This research aims to analyse the influence of genders to the width of maxillary central incisor Minangkabaunese. The study was conducted using cross-sectional method in Luhak Agam, Luhak Tanah Datar and Luhak Lima Puluh Kota, West Sumatra using simple random sampling technique to a total of 120 samples. Teeth width was measured in mesiodistal dimension with 0.01 mm calibrated sliding digital caliper. The measurement was done on a tooth mould at ⅓ incisal as the position of mesial and biggest distar. T-test independent statistic test was done to determine the relationship between the 2 variables. Sexual dimorphism was determined with Garn formula. The research shows significant difference (p=0.001) between the width of left and right central incisor in males and females. The average width of the male and female right maxillary incisor is 8.545 mm and 8.370 mm, while the left central incisor width is 8.877 mm in male and 8.283 mm in females. Sexual dimorphism on the right central incisor is 2.09% and 3.43% on the left side. The conclusion of the study is that maxillary central incisor width can distinguish different genders in the identification process.

Determining gender is one of the most important procedure in forensics. Teeth are made of the most enduring mineralized tissues in the body, as such, they have an extraordinary resistance to putrefaction and the effects of external agents (physical, thermal, mechanical, chemical or biological) which makes them invaluable material for anthropological, genetic, odontologic and forensic examinations.i)To assess the degree of sexual dimorphism in maxillary canine using maxillary canine index, maxillary first molar and central incisor using mesiodistal (MD) and buccolingual/buccopalatal (BL) dimensions of the crown. ii) To determine the accuracy of maxillary canine index, first molar and central incisor dimensions (mesiodistal and buccolingual/buccopalatal) in determining sex.This study consisted of total 30 participants (males=15, females=15) of age group ranging from 20 to 35 yrs. Measurement of dimensions of selected teeth were performed on maxillary cast using digital Vernier caliper, resolution 0.01mm. Data thus obtained were analyzed statistically.The mean values of all the measurements in males were greater than females. There was statistical significant difference in mean value of bucco-lingual width of molar, mesiodistal width of canine (on left side, right side and average) and the inter-canine distance between males and females. The buccolingual width of molar showed the highest % of sexual dimorphism (5.33%) and the mesiodistal width of molar showed the least % of dimorphism (0.7%). Bucco-lingual width of molar posed the highest prediction accuracy for gender determination. We conclude that buccolingual width of maxillary first molar can be used to predict the gender when only teeth of maxillary arch are available for forensic examination.

Chi Square Test

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

Background: An attractive smile is often attributed to incisor alignment and proclined or retroclined incisors could contribute to a less aesthetic smile. Objectives: This study was aimed to evaluate the maxillary central incisor crown inclination, crown angulation and tooth size variation in aesthetic and unattractive smiles. Methods: This study was conducted among 100 females (equally divided into aesthetic and unaesthetic smile groups), aged between15 - 25 years, with Angle’s Class I normal occlusion and balanced profiles. Variations in maxillary central incisor crown inclination and angulation were measured on lateral cephalograms, photographs and the study models of the subjects. Variations in tooth morphology were also evaluated by measuring crown height and width in both groups. Mann-Whitney U test was performed to evaluate the difference between the aesthetic and unaesthetic smiles. P < 0.05 was considered as significant. Results: This study showed that incisor angulation was significantly higher in the unaesthetic group compared to the aesthetic group (P < 0.001). However, there was no statistically significant difference for the incisor inclination relative to the Palatal Plane between the aesthetic and unaesthetic smile groups (P = 0.086). In addition, there were significant differences between the aesthetic and the non-aesthetic groups regarding the central incisor height (P < 0.05). Conclusions: The findings of this study indicate that the possible variations in aesthetics are related to the ethnic elements that are associated with differences in crown angulations, as well as tooth size.

Background: Hypertension has a great impact on cardiovascular disease and death all over the world. Low and middle-income countries including Nepal are facing higher disease burden because of complications arise from uncontrolled hypertension. Patient’s knowledge and perception play an important role for the proper management of hypertension. There are limited studies related to knowledge and perception of hypertension, therefore, this study aimed to assess the knowledge and perception of hypertension among hypertensive patients at a tertiary hospital in Nepal. Methods: This is a hospital based, mixed-method, cross-sectional study which was conducted among 400 hypertensive patients in the outpatient department of Sahid Gangalal National Heart Center, Kathmandu, Nepal. Patients who were diagnosed as hypertensive at least 6 months before were selected by simple random sampling technique and were interviewed using semi- structured questionnaire, and interview schedule from March to May 2019. Data were analyzed using descriptive and inferential statistics.    Results: The mean age of the respondents was 58.86 ±11.07 years and nearly half (47.8%) of them were in the age group of 60 years and above. More than half, (58%) were male, 77.8% were overweight, about half of them had a significant family history of hypertension with first degree relatives. Regarding the knowledge, the total mean score was 16.16±3.032 and had significant difference with age (p= 0.002), gender (p=.000), education (p=0.002), occupation (p=0.000), and duration of HTN diagnosis (p=0.000). Majority of them perceived hypertension as less serious illness and had significant difference with education level (p=0.001) and duration of HTN diagnosis (p=0.000). Conclusions: Majority of participants had inadequate knowledge of hypertension and they perceived hypertension as less severe illness which might hinder the adherence to treatment recommendations. Hence, mass awareness program strategies might be helpful to increase hypertension related knowledge and perception.

Introduction. Tooth color can be represented in a three-dimensional color system by applying L* (lightness), a* (red-green color tone) and b* (yellow-blue color tone) coordinates. Clinically significant color difference, Delta-E, can be expressed in units that are correlated with visual perception using the International Commission on Illumination L*a*b* system. The aim of the study was spectrophotometric analysis of the natural maxillary central incisor color, and to establish any gender-related differences in lightness, red-green tone, and yellow-blue tone coordinates. Material and Methods. The study included 80 students (40 male and 40 female, with an average age of 22 years). The color of the maxillary right central incisor was determined using an intraoral spectrophotometer and VITAPAN Classical and VITA 3D-Master color shade guides. Lightness, red-green tone, and yellow-blue tone values were recorded for each result. The obtained data were processed by using ?2, Student?s t-test and Mann-Whitney test. Results. Results showed no statistically significant gender-related difference in color according to the VITApan Classical and VITA 3D-Master color key. No difference was found in the lightness of the central maxillary incisor between genders, or in terms of red-green tone (p = 0.860573). A statistically significant difference was found when observing the sex-related yellow-blue tone of the color of the central maxillary incisor. Conclusion. The analysis of colorimetric parameters of the International Commission on Illumination L*a*b* system provides useful information about the tooth color in the examined population, while potentially revealing differences in lightness, red-green tone and yellow-blue tone between genders.

The Impact

Indonesia has the highest prevalence of smoking (50.68%) compared to other ASEAN countries. On January 1st, 2017, the Indonesian government raised cigarette excise taxes. The purpose of this study was to analysis the impact of cigarette excise increase on cigarette consumption among adolescents aged 17 to 25 years. The study design used cross-sectional survey. A total of 153 adolescents were recruited in this study through simple random sampling technique. Questionnaires and observation papers were used in this study. A face-to-face interview was conducted to fulfill the data collection through home visit for each respondent. The data were obtained during May – June 2017. This study used paired t test analysis. The number of cigarettes consumed by adolescent decreased significantly by two cigarettes per day after the increase in cigarette excise tax. There is a significant difference of the average cigarettes price based on the brand after the implementation of cigarette excise tax increase, the difference of cigarette price is IDR 200 per stick of cigarettes after excise tax increase. Increased cigarette excise taxes may affect the increasing of cigarette prices. Threfore, it could reduce the number of cigarette consumption.

Abstract Background Cancer of the prostate (CaP) is a public health problem that affects the male genitourinary system causing a significant threat to men’s quality of life (QoL). Experiencing financial constraints and poor illness perception may further compromise the QoL of men with CaP. Methods Aim: To examine the relationship between financial toxicity and illness perception with quality of life in men with CaP. The descriptive cross-sectional study used simple random sampling technique to recruit 173 men with CaP from four tertiary health facilities in Nigeria. Data were collected with the comprehensive score for financial toxicity (COST-FACIT), the brief illness perception questionnaire (Brief IPQ) and the functional assessment of cancer therapy-prostate (FACT-P). Analysis of data was carried out using analysis of variance, correlation and hierarchical regression analyses. Results The 173 participants had an average age of 71.57 ± 11.18, and 53.18% had one comorbid disease. Significant difference was found in overall QoL based on treatment site and number of comorbid diseases (P < 0.01). QoL had a significant inverse relationship with all the illness perception variables and a significant linear relationship with lower financial toxicity (P < 0.01). Furthermore, financial toxicity (P < 0.05) and four illness perception variables: consequences, identity, concern and illness understanding (P < 0.01), had significant individual influences on QoL of men with CaP. Conclusions Quality of life in men with CaP may be improved through mitigating the financial toxicity associated with accessing care and providing appropriate counseling about the illness and what to expect following prostate cancer diagnosis and during treatment.
