A pyramidal molar is which has completely fused roots with a solitary enlarged canal. The purpose of this retrospective study was to assess the prevalence and characteristics of pyramidal molars among adolescent.<br/>A total of 1,612 patients’ panoramic radiographs were screened. A total of 12,896 first and second molars were evaluated. The relative incidence and the correlations regarding the location of pyramidal molar (maxillary versus mandibular) and gender were analyzed using the chi-square test.<br/>The overall incidence of patients with pyramidal molars was 1.49%. 24 patients were found to have a pyramidal molar and it was more prevalent in women (18 women and 6 men). The prevalence of pyramidal molars from all first and second molars examined was 0.31%. 88 percent of pyramidal molars occurred in maxilla. All pyramidal molars were second molar.<br/>Pyramidal molar has a relatively poor periodontal prognosis compared with common multi-rooted teeth and it is important to understand the structural characteristics of root canal during pulp treatment. Clinicians should be able to understand the anatomical properties of pyramidal molar and apply it to treatment and prognostic evaluation.

Objective: To determine the prevalence and distribution of premature eruption and agenesis of premolars in a sample of Turkish children. Study design: A sample of 1715 patients aged 5 to 11 years was selected. Panoramic radiographs were used to assess premature eruption and agenesis of premolars. Developmental stage of erupted premolars was assessed using Demirjian’s method and selecting prematurely erupted premolars on the basis of clinical eruption with a root length less than half of their final expected root lengths. Statistical analysis was performed using chi-square test (p &lt;.05). Results: One hundred fifteen (6.7%) of 1715 patients presented at least one premolar agenesis with no significant sex difference (56 boys, 59 girls). Mandibular second premolars were the most absent teeth. Multiple agenesis of premolars (3.4%) was more common than single agenesis (3.3%). A total of 85 (5.0%) patients (51 boys, 34 girls; no significant sex difference) had at least one prematurely erupted premolar, and maxillary first premolars were most commonly affected. Early erupted premolars were in stage D or E based on Demirjian’s dental formation scale. Conclusions: The prevalence of premature eruption and agenesis of premolars in Turkish children were 5.0% and 6.7%, respectively. Both conditions are not uncommon and may highlight the need for early diagnosis to prevent subsequent clinical problems.

The aim of this study was to determine the frequency and distribution of mandibular teeth treated by single visit root canal treatment (RCT) and multi-visit RCT in a group of the Indian population. With the approval of the Institutional Review Board of Saveetha Dental college, the data of 3887 patients between June 2019 to March 2020 were retrieved and analysed. Data was collected from 3887 patients and were divided into the criteria of a single visit and multi-visit RCT. The data were tabulated into excel sheets under the headings age, gender, teeth, type of treatment. It was an Institutional based Retrospective study. It was observed that there was a statistically significant association in the age and gender of patients who underwent single visit and multi-visit RCT in mandibular teeth. The probability value P<0.05 was obtained after performing a Chi-square test, showing that multi-visit RCT cases (59.9%)were higher than single visit RCT (40.56%). Within the limitations of the study, it was concluded that the frequency of multi-visit RCT was higher in mandibular teeth compared to single visit RCT. Frequency of multi-visit RCT was higher in mandibular molars followed by second premolars in comparison to single visit RCT. The frequency of multi-visit RCT was higher in both males and females compared to single visit RCT.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.

Background—Intimate partner violence (IPV) has both direct and longer-term effects on children’s well-being. Much of the research thus far has relied on caregiver reports of IPV and clinical samples of children. By contrast, minimal research has examined violence between parents from the perspective of children using nationwide samples. Objective—This study explored the frequency of IPV witnessed by children and gender variations regarding the victims, perpetrators, and witnesses. Methods—The data were derived from a sample of 11,364 children from the Finnish Child Victim Survey 2013. The children were between 11 and 17 years old and were enrolled in the Finnish school system. The main methods of analysis included crosstabulation and the chi-square test. Results—The results indicate that children witnessed more IPV against their mother (4.9%) than their father (3.5%). Girls reported having witnessed more violence against both their mother (7.0%) and father (5.1%) than boys did (mothers 2.7%, fathers 1.8%). Girls’ reports of IPV against both parents were twice or more than twice as common as boys’ reports. Conclusions—The above differences might result from gendered expectations and boys’ and girls’ different relationships to violence, as well as differences in the recognition and interpretation of violent incidents. Therefore, practitioners should adopt a gender-sensitive approach as a precondition and practice for working with children in social and health care.

AbstractSelf-assessment is vital for online learning since it is one of the most essential skills of distance learners. In this respect, the purpose of this study was to understand learners’ self-assessment quiz taking behaviours in an undergraduate level online course. We tried to figure out whether there is a relation between self-assessment quiz taking behaviours and final exam scores or not. In addition, we investigated how self-assessment quiz taking behaviour differs with respect to learner profile. In line with this purpose, 677 students’ 6092 test events across Project Culture course on Sakai CLE LMS were analyzed. For the analysis of the quantitative data, one-way ANOVA, Chi-Square test of independence, independent-samples t-test and descriptive statistics were utilized. The results revealed that learners who attended self-assessment quizzes regularly had higher final exam scores than others who did not attend those quizzes. Also, they were more satisfied with the course than others study field. In addition, learners who attended selfassessment quizzes regularly had a higher degree of perceived learning. However, number of attempts to those quizzes does not have an effect on final exam scores. On the other hand, a statistically significant relationship was found between attempt number and gender in favour of female learners.

Objective: This study was carried out to determine the prevalence of microdontia among patients undergoing orthodontic treatment. Materials and Methods: This was a cross-sectional study conducted at Sindh Institute of Oral Health Sciences, (JSMU) from January-2020 to May-2020. Pre-treatment casts were taken of 140 subjects. The mesiodistal dimension of each tooth was recorded through the vernier caliper. Frequency and percentage were calculated for the presence of microdontia. The test applied was Pearson’s Chi-square test to assess the relationship between microdontia and variables like age and gender. P-value <0.05 was taken as statistically significant. Data analysis was performed on SPSS version 22. Results: A total of 140 subjects were selected i.e. 105 (75%) females and 35 (25%) males aged range 13 -30 years with mean age 18.29 ± 3.88. Out of 42, single tooth microdontia was found in 3 (7.1%), more than one tooth microdontia, and generalized microdontia was present in 36 (85.7%) and 3 (7.1%) respectively. Microdontia was found to be more common in the maxilla (n=42, 100%) than the mandible (n=14, 33.3%). It was found more common in females (n=37, 35.2%) as compared to males (n=5, 14.3%). Statistically significant relationship was found among gender and prevalence of microdontia (p=0.019) with a statistically insignificant relationship between age and presence of microdontia (p=0.228). Conclusions: Microdontia was found to be a frequent dental anomaly, was more common in maxilla and females with a significant association with gender.

Objective: Triticeous cartilage is a small ovoid structure belonging to the laryngeal skeleton. When calcified, it becomes visible on panoramic radiographs and be mistaken for a carotid artery calcification (CAC) associated with cerebrovascular accidents. This study aimed to estimate the prevalence of calcified triticeous cartilage (CTC) detected by means of digital panoramic radiographs in a sample of Lebanese population. Materials and Methods: Digital panoramic radiographs of 500 Lebanese adult patients (281 females and 219 males) with a mean age of 47.9 years were included in this study and examined for CTC. The IBM® SPSS® for Windows version 20.0 (SPSS, Chicago, IL, USA) was used to carry out statistical analysis of the data collected. Results: Nearly 10.6% (53 out of 500) of the radiographs examined presented CTC. Of all the calcifications, 11 were on the right side, 5 on the left side, and 37 were bilateral. The cases detected belonged to 31 females and 22 males with an average age of 55.6 years (ranging from 24 to 85 years). Chi-square test did not show any statistical connection between gender and CTC, while Spearman's correlation analysis showed low positive correlation with age (r = 0.146). Conclusion: CTC can be detected on panoramic radiographs taken in daily dental practice; its identification is essential to avoid misdiagnosis with other calcifications in the neck region closely related to life-threatening risks such as CAC.

ABSTRACT Aim The aim of this study to determine the influence of smoking on self-reported oral health status among university students. Materials and methods Voluntary sample of 669 adults of 18 to 26 years old were invited to participate in the study. They were asked to read a self-designated questionnaire and a covering letter which explained the purpose of the study. The questionnaire addressed self-reported demographics, oral hygiene and smoking habits; knowledge about smoking and its effects on oral health. Data were statistically analyzed using Chi-square test to determine statistically significant differences across the oral health status. Results The sample included 340 (56.7%) males and 240 (43.3%) females; 56.8% of the subjects were nonsmokers; 43.2% were current smokers, and 17.5% smoke argileh. Almost 24.7% of subjects started smoking because of emotional effects; 66.9% did not smoke because of its harm to health. The percentage of subjects with dental plaque on their teeth was 27.1%, and with calculus was 27.9%, and with stains was 26.9%. About 35.5% of the subjects brushed their teeth once daily. Statistically, significant association was proven between smoking and gender (p < 0.01); and smoking and halitosis (p < 0.01). Conclusion Smoking is significantly related to esthetics, calculus, tooth stains, halitosis, gingival bleeding, and gender with p < 0.01, p < 0.01, p < 0.01, p < 0.01, p = 0.05, and p < 0.01 respectively.
