Introduction: Hypodontia is the most prevalent dental anomaly that might cause clinical complications. The aim of this study is to assess the prevalence of hypodontia in relation with sex in permanent teeth, skeletal malocclusion and dental crowding among orthodontic patients admitted to Ahvaz Dental School. Materials and Methods: In this descriptive cross-sectional study, dental casts, panoramic radiographs and lateral cephalograms related to patients that were admitted to Department of Orthodontics of Ahvaz Dental School during 2018-2019 were investigated, to establish the existence of hypodontia, type of skeletal relationship, age, sex and dental crowding in the permanent dentition. The data were analyzed using a chi-square test in IBM SPSS Statistics for Windows, version 25 with statistical significance set at p value < 0.05. Results: Among 331 patients which were included 257 females (77.65%) and 74 males, prevalence of hypodontia was 9.4% (31 patients, 10.5% in females, 5.5% in males). The difference between the genders in term of hypodontia was not significant (p value = 0.257). This condition was existed from the dental and skeletal relationship point of view: hypodontia was observed in 19 patients (61.4%) with class Ⅰ relationship, 9 patients (29%) with skeletal class Ⅱ and 3 patients (9.6%) with skeletal class skeletal class ⅠⅠⅠ relationship. The difference between skeletal relationship and hypodontia was not significant (p value = 0.370). Dental crowding was observed in 24 patients (77.4%). There was not significant difference between dental crowding and hypodontia (p value = 0.276). Conclusion: Hypodontia was more prevalent in females but there was no significant difference between the prevalence of hypodontia in males and females. Previous studies have shown that the prevalence of hypodontia in Iran similar to current study.

Introduction: The angle between Frankfort horizontal (FH) plane and Sella-Nasion (SN) plane is considered to be 7°. Various studies have shown that the FH-SN angulations could vary; which can affect cephalometric diagnosis.Objective: To determine average FH-SN angle for a group of Nepalese orthodontic patients. The secondary objectives were to assess whether the FH-SN angle exhibits sexual dimorphism and to evaluate the FH-SN angle in different skeletal relationships.Materials & Method: Lateral cephalograms of 238 orthodontic patients were hand traced and the angle between the FH and SN plane was measured and recorded. The cephalograms were also classified as skeletal Class I, II or III cases using Wits appraisal.Result: The average FH-SN angle was 6.71° ± 3.13°. FH-SN angle was greater in female samples compared to males. However, the difference was not statistically significant. Similarly, the ANOVA analysis revealed no significant difference between FH-SN angles in different skeletal relationships.Conclusion: The average FH-SN angle for a group of Nepalese orthodontic patients was 6.71° ± 3.13°. There was no statistically significant difference in FH-SN angle between skeletal Class I, II and III relationships

Introduction: Gonial angle is an important parameter of the craniofacial complex which is generally used to evaluate the vertical parameters and symmetry of the facial skeleton. Gonial angle can be measured in both orthopantomogram (OPG) and lateral cephalograms. Due to the superimpositions seen while measuring the bilateral strucuture on lateral cephalograms, reliable measurement of the gonial angle becomes difficult. This study is done to clarify the possible application of orthopantomogram (OPG) for evaluating angular measurement of the mandible specifically gonial angle by comparing with lateral cephalogram. Materials and Method: All the patients (104) being treated from January 2018 to August 2020 in department of Orthodontics in Nepal Medical College were included in the study. Gonial angle measurements were made on lateral cephalograms and orthopantomograms of 104 patients – 54 males and 50 females with mean age of 22.20 ± 3.25 years. Patients aged 15-35 years were included in the study. Data was processed in SPSS version 16.0. Result: Mean Gonial angle in lateral cephalogram was greater than mean gonial angle in OPG and this difference was found to be statistically significant (p-value < 0.05). The difference in mean gonial angle was found to be statistically significant when compared between right gonial angle in OPG and gonial angle in lateral cephalogram (p-value < 0.05) and also between left gonial angle in OPG and gonial angle in lateral cephalogram (p-value < 0.05). Conclusion: When gonial angle values obtained from both sides of OPG were compared, no statistically significant difference was found. Significant differences were found when gonial angle values obtained from OPG right and left sides were compared with that of lateral cephalogram.

Background and objectives: Dental crowding is more pronounced in the mandible than in the maxilla. When exceeding a significant amount, the creation of new space is required. The mandibular expansion devices prove to be useful even if the increase in the lower arch perimeter seems to be just ascribed to the vestibular inclination of teeth. The aim of the study was to compare two activation protocols of the Schwartz appliance in terms of effectiveness, particularly with regard to how quickly crowding is solved and how smaller is the increasing of vestibular inclination of the mandibular molars. Materials and Methods: We compared two groups of patients treated with different activation’s protocols of the lower Schwartz appliance (Group 1 protocol consisted in turning the expansion screw half a turn twice every two weeks and replacing the device every four months; Group 2 was treated by using the classic activation protocol—1/4 turn every week, never replacing the device). The measurements of parameters such as intercanine distance (IC), interpremolar distance (IPM), intermolar distance (IM), arch perimeter(AP), curve of Wilson (COW), and crowding (CR) were made on dental casts at the beginning and at the end of the treatment. Results: A significant difference between protocol groups was observed in the variation of COWL between time 0 and time 1 with protocol 1 with protocol 1 subjects showing a smaller increase in the parameter than protocol 2 subjects. The same trend was observed also for COWR, but the difference between protocol groups was slightly smaller and the interaction protocol-by-time did not reach the statistical significance. Finally, treatment duration in protocol 1 was significantly lower than in protocol 2. Conclusion: The results of our study suggest that the new activation protocol would seem more effective as it allows to achieve the objective of the therapy more quickly, and likely leading to greater bodily expansion.

Abstract: Routine blood examination is the earliest blood test or screening test to determine the diagnosis of an abnormality. Blood easily froze if it is outside the body and can be prevented by the addition of anticoagulants, one of which Ethylene Diamine Tetra Acetate (EDTA). Currently available vacuum tubes containing EDTA anticoagulants in the form of K2EDTA and K3EDTA. K3EDTA is usually a salt that has better stability than other EDTA salts because it shows a pH approaching a blood pH of about 6.4. The purpose of this research is to know the difference of erythrocyte index results include MCH, MCV and MCHC using K3EDTA anticoagulant with K2EDTA. This research is a cross sectional design. This study used venous blood samples mixed with K2EDTA anticoagulant and venous blood mixed with K3EDTA anticoagulants, each of 30 samples. Data were collected and analyzed using paired different test. Based on data analysis that has been done on MCH examination, p value <0,05 then there is a significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value. Then on the examination of MCV and MCHC obtained p value <0.05 then there is no significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value.Abstrak: Pemeriksaan darah rutin merupakan pemeriksaan darah yang paling awal atau screening test untuk mengetahui diagnosis suatu kelainan.

Abstract Introduction Burn camps provide a unique environment and activities for children that have experienced a burn-injury. Positive outcomes from attending burn camp include increased self-esteem, decreased feelings of isolation and a greater sense of self-confidence. In a 3-year retrospective review of camper evaluations from one of the largest and longest running week-long burn camps in the nation for ages 5–17, we aimed to assess if a child’s gender, age, TBSA or ethnicity affected the impact that burn camp had on a child. Methods A 3-year retrospective review of a Burn Camp’s camper evaluation forms was conducted for campers that attended burn camp between 2017–2019. Camp rosters were reviewed to determine the camper gender, age, TBSA and ethnicity. Camper self-evaluation forms completed at the end of each camp session were reviewed to record camper responses to questions regarding their opinions on the impact camp had on them as well as how camp will impact their lives once they return home. Categorical variables were summarized as frequency and percentage, and continuous variables were described as median and range. To check the relationship between two categorical variables, Chi-square test was used. To compare the continuous variable among groups, Kruskal-Wallis ANOVA was used. Statistical significance was declared based on a p value&lt; 0.5. Results Within 2017–2019, there were 413 camper records. Participants’ demographic characteristics are summarized in Table 1. There were 208 males (50.3%) and 205 females (49.6%). The median age of campers were 11.86, 12.44 and 12.45 for 2017–2019, with the range from 5.16 years to 17.96 years. The median TBSA were 20, 20 and 18 for 2017–2019, with the range from 0.08 to 90. Collectively there were 47.7% Hispanic (n= 197); 24.2% Whites (n=100); 13.1% Black (n= 54); 4.6% Asian (n=19) and 7.7% Other (n=32). There were 395 camper self-evaluation forms submitted. Results of three questions there we were interested in are summarized collectively in Table 2. 57% of campers responded, “Yes, Definitely” to the question “After going to this event, will you feel more comfortable being around your classmates or friends?” 54% responded, “ Yes, Definitely” to the question “Do you feel more confidents in sharing your burn story with others when returning home?” and 51% responded “Yes, Definitely” to “Did you learn anything that will help you when you return home?” Conclusions In analyzing the camper responses, there was no statistically significant difference in responses comparing gender, age, TBSA or ethnicity.

Background. The aim of this study was to compare the cyclic fatigue resistance of 2Shape, Twisted File (TF) and EndoSequence Xpress (ESX) nickel-titanium rotary files at intracanal temperature (35°C). Methods. Twenty 2Shape TS1 (25/.04), 20 TF (25/.04) and 20 ESX (25/.04) files were tested for cyclic fatigue at intracanal temperature (35°C). All the instruments were rotated in artificial canals which were made of stainless steel with an inner diameter of 1.5 mm, 60° angle of curvature and a radius curvature of 5 mm until fracture occurred; the time to fracture was recorded in seconds using a digital chronometer and the number of cycles to fracture (NCF) for each file was calculated. Kruskal-Wallis test with Bonferroni correction was performed to statistically analyze data using SPSS 21.0. Statistical significance was set at P<0.05. Results. NCF values revealed that the 2Shape had significantly the highest cyclic fatigue resistance, followed by TF and ESX at intracanal temperature (P<0.05). The difference was significant between the TF and ESX groups (P<0.05). There was no significant difference among the 2Shape, TF and ESX files with respect to the lengths of the fractured file fragments (P>.05). Conclusion. Within the limitations of present study, it was concluded that the cyclic fatigue resistance of 2Shape files at the intracanal temperature is higher than that of TF and ESX files.

Endovascular treatment is a rapidly evolving technique; therefore, there is a constant need to evaluate this method and its modifications. This paper discusses a single-center experience and the results of switching from the stent retriever only (SO) mechanical thrombectomy (MT) to the combined approach (CA), with a stent retriever and aspiration catheters. Methods: The study involved a retrospective analysis of 70 patients undergoing MT with the use of either SO or CA. The primary endpoint was the frequency of perfect reperfusion defined as grade 3 of the modified Thrombolysis in Cerebral Infarction scale (mTICI) after the first pass. The secondary endpoints were the procedure success, defined as mTICI grades 2b-3; time of the procedure; clinical outcome, measured by 90 days’ modified Rankin Scale (mRS) score; Δ NIHSS, defined as the difference between National Institutes of Health Stroke Scale (NIHSS) score at patients’ admission and discharge; and the total number of device passes. Results: Out of the 70 patients included, 33 were treated with SO and 37 with CA. In both groups, a total number of 42 patients received intravenous recombined tissue plasminogen activator (iv-rTPA: 20 patients (60.6%) in the SO group and 22 patients (59.5%) in the CA group (p = 1.000). There was a significant difference between the groups regarding first-pass success rate, with 46% in the CA group and 18% in the SO group, (OR 3.83, 95% CI 1.28 to 11.44, p = 0.016). Complete procedure success tended to be more frequent in the CA group than in the SO group—94.6% vs. 84.8% (OR 3.13, 95% CI 0.56 to 17.34, p = 0.193)—and CA tended to require a lower number of passes than SO (mean 1.76 vs. 2.09 passes per procedure, p = 0.114), yet these differences did not reach statistical significance. Mean duration of the procedure was significantly shorter in the CA group than in the SO group (49 min vs. 64 min, p = 0.017). There was a significant difference in clinical outcomes, with higher Δ NIHSS (9.3 in the CA group vs. 6.7 in the SO group, p = 0.025) after the procedure and 90-day mRS (median 2 in the CA group vs. 4 in the SO group, p = 0.031). Conclusions: Combining stent retrievers with aspiration catheters may offer a beneficial effect on angiographic results and clinical outcomes in stroke patients undergoing endovascular treatment.

Objectives: To assess the concepts of complete denture occlusion among dental fraternity. Study Design And Setting: Cross-sectional study conducted at various dental hospitals and institutes of Karachi, for a period of six months, from 1st June’2019 to 30th November’2019 Methodology: Total 849 dental practitioners who are currently practising were included. A well-structured and validated questionnaire was used for data collection. SPSS version 25 was used. Results: Bilateral balanced occlusion was an ideal occlusion by majority subjects i.e, 530(62.4%) in patients with wellformed ridges, followed by 464(54.7%) candidates with skeletal class 1, total 376(44.3%) chose it with uncontrolled diabetes mellitus, 365(43%) in single complete denture cases, 339(39.9%) with increased inter-arch space, 298(35.1%) with parafunction habits, 296(34.9%) in patients with history of neuromuscular disorder and 271(31.9%) where a complete denture opposes a removable partial denture. Furthermore, Lingualized occlusion was preferred by 341(40.25%) participants for patients with skeletal class 3. Total 316(37.2%) candidates chose it for patients with displaceable supporting tissue followed by 264(31.1%) who chose it for skeletal 2 and 260(30.6%) for cases of highly resorbed ridges. Lastly, 311(36.6%) chose canine guided occlusion with highly resorbed ridges accompanied by high aesthetic demand A significant difference between education level and knowledge of occlusal schemes was also found. Chi-square (73.87), df 6, p-value =0.000. Conclusion: Dental practitioners lack adequate knowledge of occlusal schemes in terms of prescription in complete denture patients. A significant difference between the education level and knowledge of occlusal schemes was found. Therefore, awareness of various occlusal schemes should be increased at undergraduate level.

Introduction: An accurate measurement of blood pressure (BP) is critical to diagnosing and treating hypertension (HTN). Manual office BP (MOBP) often results in higher readings than automated office BP (AOBP). In previous studies, a repeat MOBP by a physician resulted in a lower BP than the initial MOBP by nursing staff. We evaluated our hypothesis that a repeat MOBP by a physician is statistically equivalent to AOBP. Methods: In an ambulatory outpatient setting, patients were roomed and at least a 5-minute interval lapsed before an AOBP was performed using a Welch Allyn Connex Vital Signs Monitor. The physician was blinded to the AOBP. The physician then entered the room and obtained a MOBP with a manual aneroid sphygmomanometer. The difference between the AOBP and the MOBP was calculated. A Wilcoxon signed rank sum test was used to determine if a significant difference between AOBP and MOBP exists. Results: A total of 186 patients (112 females, 74 male) had BP measured with a mean age of 66 years. AOBP resulted in a median systolic BP (SBP) 136 mmHg (IQR 121-150 mmHg) and median diastolic BP (DBP) of 78 mmHg (IQR 72-85 mmHg). MOBP SBP had a median of 132 mmHg (IQR 120-142 mmHg) and DBP had a median of 76 mmHg (IQR 70-81 mmHg). SBP and DBP were significantly lower in the MOBP group with a mean difference between AOBP and MOBP of 4.0 and 2.7 mmHg respectively (p-value of <0.0001). Conclusions: Repeat MOBP performed by the physician resulted in a significantly lower BP compared to AOBP. The lower BP may be due to an overall longer interval between the AOBP measurement and MOBP measurement. MOBP may be a viable option for accurate diagnosis and treatment of HTN clinics without access to a AOBP machine.
