Abstract Objective: To analyze the prevalence, distribution, clinical features, and relationship with dental anomalies of maxillary canine impaction. Materials and Methods: The complete pretreatment records of 1674 orthodontic patients were examined. Subjects with maxillary impacted canines were divided into two study groups: a palatally displaced canine (PDC) group (114 patients) and a buccally displaced canine (BDC) group (37 patients). These were compared to a control group of 151 patients who were randomly selected from the initial sample without maxillary canine impaction. The significance of associations between canine impaction and dental and clinical features and anomalies was examined with the chi-square test. Results: PDC patients presented with normal overjet and facial profile and a lower degree of dental arch crowding in comparison to the control patients. PDC patients showed a higher prevalence of impaction of other teeth, dental aplasia, transposition, and peg-shaped maxillary lateral incisors (odds ratios 3.3, 2.6, 8.3, and 5.8, respectively). Conclusion: PDC was frequently the only orthodontic problem of patients. BDC group patients did not present with notable differences in clinical and dental features or dental anomalies compared to control subjects.

Abstract Objective: To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA). Materials and Methods: Subjects were 120 adult Malays aged 18 to 65 years (mean ± standard deviation [SD], 33.2 ± 13.31) divided into two groups of 60. Both groups underwent clinical examination and limited channel polysomnography (PSG). The mean OSA and control values were subjected to t-test and the chi square test. Results: Physical examination showed that 61.7% of the OSA patients were obese, and 41.7% of those obese patients had severe OSA. The mean body mass index (BMI) was significantly greater for the OSA group (33.2 kg/m2 ± 6.5) than for the control group (22.7 kg/m2 ± 3.5; P < .001). The mean neck size and systolic blood pressure were greater for the OSA group (43.6 cm ± 6.02; 129.1 mm Hg ± 17.55) than for the control group (35.6 cm ± 3.52; 114.1 mm Hg ± 13.67; P < .001). Clinical examination showed that the most frequent findings among OSA groups when compared with the control group were convex profiles (71.7%), Class II malocclusion (51.7%), and V palatal shape (53.3%), respectively; the chi square test revealed a significant difference in terms of facial profile and malocclusion class (P < .05), but no significant difference in palatal shape was found. Conclusion: The null hypothesis is rejected. A convex facial profile and Class II malocclusion were significantly more common in the OSA group. The V palatal shape was a frequent finding in the OSA group.

Abstract Objective The purpose of this study was to find the prevalence of dental abnormalities in patients with third molar agenesis, and a comparison was made for the prevalence of those anomalies within the north Indian natives. Materials and Methods Pretreatment records of 518 patients were collected. Out of 518 patients whose records were analyzed, 472 patient records were selected on the basis of inclusion and exclusion standards. Panoramic radiographs and dental casts were analyzed in patients who had an absence of at least one third molar in which absence of any other tooth, presence of supernumerary teeth, presence of impacted canines, and peg-shaped lateral incisors were further assessed. The prevalence of these anomalies was compared with a randomly selected group of patients with presence of third molars that served as controls. Statistical analysis was done using the chi-square test (p < 0.05) and odds ratio. Results The incidence of third molar nondevelopment was found to be 19.2%. The presence of other anomalies was 39.5% in patients with third molar nondevelopment, and difference was statistically significant. The occurrence of impacted canines in patients with absence of third molars was 22%, and presence of third molars was 6.6%. The presence of other dental anomalies, that is, supernumerary teeth and tooth agenesis, was 7.7% in the agenesis group, which was also higher than that in the control group (3.3%) but was not statistically significant. The incidence of peg-shaped lateral incisors was similar in both the groups. Conclusion Impacted canines and total dental anomalies are more often related with absence of third molars than with the presence of third molars.

Objectives: The aim of this qualitative study was to examine orthodontic patients’ thoughts and experiences about the invisible orthodontic treatment options – lingual braces and Invisalign – through the analysis of Twitter posts’ content. Materials and Methods: A software program was written for the data collection. The program consecutively collected the tweets posted over an 8-month period from Twitter’s publicly accessible database. Tweets that were written in the English language and contained any of the four keywords “Invisalign,” “lingualorthodontics,” “lingualbraces,” and “invisiblebraces” were collected. The tweets that included irrelevant or incoherent posts, professional advertisements, unclear/not applicable content, and reposts were excluded from the study. Two authors, with different experiences, independently read, and analyzed the tweets. Each applicable tweet was classified into one of the three categories: Positive, negative, and neutral for two study groups (Invisalign and lingual braces). Pearson Chi-square test was used to analyze the negative and positive tweet rates of the groups. Results: 1176 of 2407 tweets were selected as applicable and analyzed by the authors. There was a statistically significant very good agreement between the two observers (Kappa = 0.933, P < 0.001). The negative comment rate (39%) and neutral comment rate (31.1%) in the lingual group were statistically higher than the Invisalign group (27.2% and 21.7%, respectively; P < 0.001). The positive comment rate in the Invisalign group was significantly higher (51.1%) compared to the lingual group (29.9%, P < 0.001). Conclusion: Orthodontic patients use social media to share their experiences and feelings about their treatment process. The applicable Tweet number and the positive Tweet rate in the Invisalign group were higher than the lingual braces group.

Introduction: Dental anomalies are commonly seen during regular dental check-up. It occurs due to abnormal morphodifferentiation of teeth during different stages of tooth development. The purpose of this study was to find out the of dental anomalies among orthodontic patients of Kathmandu, Nepal. Materials & Method: A total of 601 patients (242 males and 359 females) of aged 10 to 35 years (mean age= 16.42±3.42 years) who require orthodontic treatment were selected. The patients were assessed clinically and dental panoramic radiographs were evaluated for disturbance in number and other anomalies. A chi-square test was used to determine the difference in the prevalence of dental anomalies between genders and among different classes of malocclusion. Result: The prevalence of dental anomalies was 15.3% that is 92 participants were exhibited at least one dental anomaly among 601 orthodontic patients. Among dental anomalies, hypodontia was the most prevalent (7.48%) followed by hyperdontia (2.99%), microdontia (2.16%), macrodontia (0.66%), transposition (0.66%), taurodontism (0.49%), double teeth (0.33%), amelogenesis imperfecta (0.33%) and dentinogenesis imperfecta (0.16%). The prevalence of oligodontia was 0.33%. There were no statistically significant difference in prevalence of anomalies in between gender and among different classes of malocclusion. Conclusion: Prevalence and distribution of some dental anomalies in orthodontic patients of Kathmandu differed from other studies. Maxillary lateral incisor was the most commonly missing and microdontic tooth. Orthodontists have the responsibility to observe each patient carefully for dental anomalies to correct or improvise this condition without any complications.

Background: Riskesdas in 2013 showed that Yogyakarta (DIY) had a prevalence of stunted new kid in school is less than the national average, which is 14.9% (MOH, 2013). Stunted or short, is a linear growth retardation has been widely used as an indicator to measure the nutritional status of individuals and community groups. Stunted can be influenced by several factors: birth weight, birth length match and genetic factors. Objective: To determine the weight, length of low birth weight and genetic factors as predictors of the occurrence of stunted on elementary school children. Methods: The study was a case control analytic. Research sites in SD Muhammadiyah Ngijon 1 Subdistrict Moyudan. The study was conducted in May and June 2015. The subjects were school children grade 1 to grade 5 the number of cases as many as 47 children and 94 control children. With the inclusion criteria of research subjects willing to become respondents, was present at the time of the study, they have a father and mother, and exclusion criteria have no data BB and PB birth, can not stand upright. The research variables are BBL, PBL, genetic factors and TB / U at this time. Data were analyzed by chi-square test and Odd Ratio (OR) calculation. Results: In case group as much as 91.5% of normal birth weight and length of 80.9% of normal birth weight, most of the height of a normal mother and father as many as 85.1%. In the control group as much as 78.7% of normal birth weight and 61.7% were born normal body length, height mostly normal mom and dad that 96.7% of women and 90.4% normal normal father. Statistical test result is no significant correlation between height mothers with stunted incidence in school children, and the results of chi-square test P = 0.026 with value Odd Ratio (OR) of 3.9 and a range of values from 1.091 to 14.214 Cl95%. Conclusion: High maternal body of mothers can be used as predictors of the occurrence of stunted school children and mothers with stunted nutritional status have 3.9 times the risk of having children with stunted nutritional status.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Abstract α-tocopherol is known to be a powerful antioxidant, in this regard, it was added to bovine oocyte in vitro maturation media to evaluate its effect on oocyte maturation. Oocytes (n = 624) aspirated from ovaries of slaughtered cows were classified by quality and divided in four categories according to cytoplasm appearance and cumulus cells layers. Oocytes were washed in TCM-199 supplemented with fetal bovine serum (FBS) and FSH, then distributed in maturation media (TCM-199 supplemented with FBS, FSH and gentamicin). Three experimental groups of α-tocopherol (50, 100 and 200 mM) and a control group without α-tocopherol were used. Maturation was carried 22 h at 38.5°C in a 5% CO2 atmosphere. Oocytes were examined to determine cumulus expansion as categorical data (expansion or no expansion), as well as cumulus expansion Index (CEI). For CEI determination oocytes were graded 0 to 4, being 0 those with null expansion and 4 those with a noticeable cell expansion, then the number of oocytes were multiplied by the grade given and a sum of the totals was obtained, the new total was divided by the total of oocytes in the group and the result obtained corresponded to the CEI of the group. Results were analyzed with Chi Square test (for maturation rates) and an ANOVA (for the CEI) using the SAS system, data are presented as mean ± standard error. There was no statistical difference between control and α-tocopherol groups (P &gt;0.05). Numerically, the control group showed a higher maturation rate (100%) and obtained a higher CEI (2.44±0.20), followed by the 50 mM group (98.16%; 2.39±0.13), the groups 200 mM (97.40%; 2.00±0.14) and 100 mM (96.25%; 2.06±0.24) were the lowest. The addition of the minimum concentration (50 mM) of α-tocopherol to the maturation media could improve maturation rates without exposing oocytes to toxic effects.

Clinicians should appreciate the effectiveness of virtual reality (VR) headsets for managing both the anxiety and the behaviour of non-cooperative paediatric patients who require treatment over several dental appointments. The aim of this study was to assess the effectiveness of using a VR headset as a distraction for managing the anxiety and behaviour of paediatric patients during their dental treatment. Eighty patients, aged between five and ten years old and who required dental treatment over three or more appointments, were randomly allocated into two groups. One group used a VR headset during all their appointments, and the other one did not use any distraction technique. The patients were asked to take a Facial Image Scale Test during their first and last appointments to assess their level of anxiety. Additionally, the dentist completed the Frankl Test to quantify the child’s behaviour at the beginning and the end of their treatment. The results obtained, both from the group using the VR headset and from the control group, were compared using the chi-square test. The use of a VR headset during dental treatment significantly reduced anxiety (95% of the children were happy) and improved behaviour (100% positive behaviour) as compared with the control group (40% and 57.5%, respectively). A VR headset can effectively distract a paediatric patient, helping to reduce anxiety and manage behaviour during dental treatment
