Background. Supernumerary tooth is defined as any extra tooth or odontogenic structure that is formed on normal dentition. Supernumerary teeth cause such problems as deficiency in tooth growth, ectopic growth, displacement, crowding, diastema, odontogenic cyst formation, decay of the adjacent tooth, malocclusion, and esthetic problems. This study was conducted aiming at determining epidemiology of supernumerary teeth in Ardabil city in 2020. Materials & Methods. In this retrospective descriptive analytical study, 5000 panoramic radiographs of patients referring to Rad and Baser Oral and Maxillofacial Radiology Centers were selected through multistage sampling method during 2015–2020. The data were collected by checklist and analyzed with using SPSS-21 and chi-squared, Fisher, and one-way ANOVA tests with a significance level less than 5%. Results. The prevalence of supernumerary teeth was estimated as 1.06% (n = 53), and no significant difference between the males and females was seen. Most supernumerary teeth were found in the distomolar (44.1%) and parapremolar (29.4%) locations. The majority of supernumerary teeth were present in the maxilla (73.5%) and were impacted (77.9%) and unilateral (71.7%). The number of supernumerary teeth was 68 cases and majority of patients (86.8%) had one supernumerary tooth. Conclusion. Supernumerary tooth in this study had a high prevalence compared to similar studies, and unlike most previous studies, the most common type of supernumerary tooth was distomolar. Early diagnosis and proper medical planning are essential for managing supernumerary teeth.

The study looked at gender as it relates to academic performance of students in Agriculture Primary School Leaving Examination in Gaborone schools. The research was quantitative ex-post facto type design. The sample composed of 3781 (1751 males and 2030 females) students who wrote PSLE in 2012. The sample was taken from 43 primary schools in Gaborone area which included private and government schools. The results which included students’ scores were obtained from Botswana Examinations Council academic records and were not manipulated in any way. The results were then subjected to testing using Statistical Package for Social Sciences at significance level of 0.05. An independent t-test was conducted to determine significance difference and value of -5.964 which is statistically significance (P = 0.00) obtained and therefore the null hypothesis that states that there is no significant difference between males and females was rejected. The analysis revealed that girls performed better than boys and moreover there is a significant difference between males and females’ academic performance. It was therefore, recommended that the Gaborone Regional Education office intensify research to establish how other variables such as location, parental support and economic status of parents contribute to poor Primary School leaving Examinations.

Background: Social health is defined as the individual’s ability to effectively and efficiently play social roles without hurting other people. It is the examination of an individual’s activities and status in society. Saffron cultivation, given its special properties, such as teamwork, cooperation, and social correlation, plays a major role in social health. Thus, the current study was done to compare the social health components among the farmers in saffron villages and the others in South Khorasan Province. Methods: The current study was applied and comparative. The statistical population included the farmers in saffron villages and the others in South Khorasan Province in 2018. The sample consisted of 550 farmers (275 producing saffron and 275 producing other plants) based on the Cochran formula who were selected through multistage sampling. The tool used to collect the data was Keyes’s standard Social Well-being Questionnaire (2004), consisting of 28 questions. After collecting the questionnaires, the data were analyzed using SPSS v. 23 and an independent t-test at a significance level of P<0.05. Results: There was a significant difference between the villagers planting saffron and other plants regarding their social health levels (P<0.000). The obtained t-value for social health, as a dependent variable, was 15.47. The obtained t-value for all the aspects of social health was higher than the acceptable t-value (P<0.05). Conclusion: The results showed that saffron villages had higher social solidarity, compared to other plants. Because cooperation and collaboration are necessary for different stages of saffron production, social cohesion is naturally reinforced

Mesiodens is the most common supernumerary tooth and is present in the midline between the two central incisors. It occurs mostly due to hyperactivity of the dental lamina. They are usually small, with a cone shaped crown and a short root, may be single or paired, erupted or impacted and occasionally even be inverted. Presence of more than one mesiodens is termed as mesiodentes. Presence of mesiodens may cause impaction or delayed eruption of permanent teeth, malocclusion leading to disturbance in chewing, swallowing and speech, root resorption of the adjacent teeth, impaired dentofacial aesthetics, and sometimes cyst formation. The erupted mesiodens can be easily diagnosed clinically, and the unerupted ones are best diagnosed by clinical and radiological evaluation. Although mesiodens is the most common supernumerary teeth, presence of double mesiodens is uncommon. In this paper we describe a case of palatally erupted double mesiodens and its management in a 20year old girl.

Abstract The objective of the present study was to determine the prevalence of actinic cheilitis among extractive mining workers and factors associated with the condition, especially the relationship between clinical appearance and the length of occupational exposure to sunlight. A cross-sectional study was performed in Dona Inês, Paraíba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student’s, ANOVA one-way, Fisher’s exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63±112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p<0.001) and aged 37.41±12.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75±97.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68±113.15; p=0.032); vertical fissures (210.09±123.07; p=0.046); white and red spotting (199.51±91.80; p=0.004); hard consistency of the lip (225.81±122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.

Introduction The aim of this study was to determine the incidence of bridging of the sella turcica and the dimensions of the Sella in subjects with dental anomalies (transpositions, hypodontia, and supernumerary teeth) and to compare them to controls. Methodology Lateral cephalograms from 25 patients with dental transposition, 88 with hypodontia, and 26 with supernumerary teeth were evaluated. The shape, length, depth, diameter, and bridging of the Sella turcica were determined from radiographs and compared to those of control group (n=52). For statistical analysis, one-way ANOVA, Tukey post-hoc test, chi-squared test and T-test (to evaluate the influence of craniofacial growth) were used. Results The frequency of complete calcification of the Sella was greater in the group with supernumerary teeth (23%) and in the group with hypodontia (14.7%), while partial calcification of the Sella was more frequent in the control group (77%) and in the group with supernumerary teeth (73%)(p<0.05). The depth of the Sella was greater in the group with dental transposition. Oval and round Sella shapes were more frequent in all groups, and a flat Sella was rarely seen. In terms of the influence of growth on the dimensions of the Sella, there was no statistically significant difference between pre- and post-treatment radiographs. Conclusion Significant relationships were found between dental anomalies and bridging and shape of the Sella. The Sella was also significantly deeper in patients with dental transposition. The bridging and shape of the Sella may be useful in the diagnosis of dental anomalies in early childhood.

INTRODUCTION: According to the World Health Organisation regarding suicide rate, Lithuania was on the top in 2016 with 31.9 suicide events per 100 000 people of the population. This research was aimed at analysing the situation including methods of suicide and its distribution between different age, gender and settlement groups in Lithuania. METHODS: 4610 particular suicide cases were found and analysed from the given retrospectively collected data by the Hygiene Institute’s Register of Death Causes in Lithuania from 2012 till 2016. These cases have been categorised into age (10-19 years old, 20-69 years old and >70 years old), gender and settlement groups. Chi-squared and Fisher tests were used to analyse the associations between the suicide methods used, sex, as well as age. A significance level of p<0.05 was used. RESULTS: In total, 4610 suicide cases were registered in Lithuania in 2012-2016. People aged 20-69 years had the biggest proportion with 80%, followed by 16% for people older than 70 and 4% people aged 10-19. 82% of all cases were men. The most common method of suicides in all age groups was hanging, self-strangulation and self-suffocation; 92%. There is no statistical significant difference in methods used by the 10-19 years old group and above 20 years of age (20-70+).A difference was found between the groups under 70 years and above 70 years old. Moreover, the following difference was found between their genders (p=0.0002). In terms of using drugs and biological substances, women (54.24%) are more likely to commit suicide through these means than men in all age groups, while 100% of suicide methods by gas, steam or solvents were used by men. Though slightly more suicides were registered in cities, there was no statistically significant difference between people living in cities and in villages. CONCLUSIONS: Despite the fact that incidences of suicides are gradually decreasing every year, the situation is not yet satisfactory. The pattern almost has not changed for years – the most inclinable person to commit suicide is a 50-59 years old man living in a city and the most used method is still hanging.

Supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch .Mesiodens is the most common type of supernumerary tooth found in the premaxilla between two central incisors. They may be single, multiple, unilateral or bilateral, erupted or unerupted in one or, both jaw. It usually results in oral problems such as malocclusion, food impaction, poor aesthetics, and cyst formation. Early diagnosis and treatment is suggested to prevent orthodontic and pathologic complications. This article highlights the orthodontic management of a case of twenty five year old Bangladeshi male with two supernumeraries- one is a supplemental tooth erupted in the oral cavity causing malocclusion and another impacted mesiodens near the nasal floor. The case was managed by a joint effort of maxillofacial surgeon and orthodontist. At first, maxillofacial surgeon removed the two supernumerary teeth. After healing the orthodontic correction was done with fixed appliance using multiloop edgewise technique. It took nearly 18 months to complete the treatment. The patient was happy with the new appearance and function. DOI: http://dx.doi.org/10.3329/bjodfo.v2i1.16002 Ban J Orthod & Dentofac Orthop, October 2011; Vol-2, No.1, 30-33

Abstract Background Connective tissue disorders could contribute to the pathogenesis of both abdominal aortic aneurysms (AAA) and hernias. We tested the hypothesis that hernias in AAA patients contribute to increased severity of the aneurysmal disease. Methods A questionnaire was used to collect information from 195 AAA patients divided into four groups: (1) survivors (n = 22) of ruptured AAA, (2) patients (n = 90) after elective open repair, (3) patients (n = 43) after elective endovascular repair (EVAR), and (4) patients (n = 40) under surveillance of AAA. The control group consisted of 100 patients without AAA whose abdominal computed tomography (CT) scans were examined for the presence of hernias. Mann–Whitney U-test, Chi-squared (χ 2) test, or Fisher's exact test (as appropriate) were used for statistical analyses. Multivariate logistic regression was used to control for potential confounding variables such as sex and age. Results The prevalence of inguinal hernias was significantly higher in the AAA than the control group (25 vs. 9%, p = 0.001) and did not differ between the AAA subgroups (9, 24, 35, and 23% in subgroups 1 through 4, respectively, p = 0.15) based on univariate analysis. The prevalence of inguinal hernias did not differ (p = 0.15) between the two open surgery groups (groups 1 and 2), or when comparing all three operative procedures as a combined group to group 4 (p = 0.73). The prevalences of incisional hernias were 18 and 24% for groups 1 and 2, respectively, with no significant difference (p = 0.39). Inguinal hernia demonstrated a significant association with AAA on multivariate analysis (p = 0.006; odds ratio [OR] = 4.00; 95% confidence interval [CI] = 1.49–10.66). Conclusions Our study confirms previous observations that patients with AAA have a high prevalence of hernias. Our results suggest that hernias do not contribute to increased severity of the aneurysmal disease.

Objective: To investigate frequency of supernumerary tooth in relation to gender, age and location. Study Design and Setting: Cross-sectional Study was conducted at Mamji Hospital, Karachi from June 2017 to June 2019. Methodology: A total of 2160 patients seen and out of which 45 clinically diagnosed patients of supernumerary teeth were participated in this study. Supernumerary teeth were classified on the basis of location. Descriptive statistics were checked by means of percentages and frequency of all variables. Chi-Square test was applied, P-value < 0.05was considered significant. Results: The total patients were 45 which comprised of 26 male and 19 females with ages ranging from 15 to 60 years. The prevalence of ST was 1.59%, the higher predilection of supernumerary teeth was seen in males than females. The male to female’s ratio was 1.36:1. On the basis of location ST were further classified on Mesiodens, Paramolars and Distomolars category. Of the 45 supernumerary teeth, 36 were had Mesiodens (m= 62.1%, f=37.8%), 5 were Paramolars (m=60%, f=40%) and 3 were Distomolars (m=0, f= 100%). Conclusion: The present study findings showed high prevalence of ST was dominant in males. Present study emphasizes the timely diagnosis and appropriate management of supernumerary teeth to avoid unwanted complications

Objective: The aim of this study was to evaluate the incidence of dental anomalies in the permanent dentition of individuals with Down Syndrome (DS) to increase the knowledge on the dental issues in this syndrome. Method: One hundred and five panoramic X-rays of patients with DS (61 males and 44 females), aged 7 to 42 years were used. The data were statistically analyzed using bivariate analyses test (p <0.05). Results: Dental anomalies were observed in 50.47% of the sample. More than one anomaly was observed in 9.52% of the individuals. The most frequent dental anomalies were hypodontia and microdontia (16.19%), followed by retained tooth (10.47%), taurodontism (9.52%), supernumerary teeth (5.71%), macrodontia (2.85%) and root dilaceration (0.95%). There was no statistically significant difference between genders for any of the anomalies. Conclusion: A high prevalence of dental anomalies was observed in individuals with DS. The results of the present study reinforce the importance of good dental care, offering a greater basis for professionals who provide dental service to these patients.
