ABSTRACT Aim This study evaluated the prevalence of the chewing side preference (CSP) in the deciduous, mixed and permanent dentitions. Materials and methods Three-hundred subjects were divided in three groups (n = 100): Group 1 – children with deciduous dentition; group 2—children with mixed dentition; group 3 – subjects with permanent dentition. The CSP was determined using a direct method (visual observation) developed by McDonnell et al. (2004). Descriptive statistic was used to observe the prevalence of CSP. The Pearson's Chi-square was used to investigate signicant associations between gender, presence of CSP and preferred side (right/left). Results and conclusion Eighty-seven percent of group 1 had a CSP. Eighty-two percent of group 2 had a CSP. Seventy-six percent of group 3 had a CSP. There was no statistically significant association between presence of CSP and gender in all groups. There was no statistically significant association between preferred side (right/left) and gender in all groups. Clinical significance There is a higher prevalence of subjects in deciduous, mixed and permanent dentition that presented chewing side preference. The early diagnosis of the presence of chewing side preference can prevent the unilateral chewing pattern with prophylactic therapy applied to the first teeth (deciduous).

OBJECTIVE: This study evaluated the use of plasma, bone surface (periosteal) and whole bone as biomarkers of chronic fluoride (F) exposure. METHODS: Forty male Wistar rats were assigned to 4 groups (n=10/gr) that differed according to the F concentration they received in the drinking water. Groups 1, 2, 3 and 4 received water containing 0 (control), 5, 15, and 50 mg F/L, respectively. The rats were killed at 120 days of age. Plasma and femur were collected and analyzed for fluoride with the ion specific electrode by the direct method or after hexamethyldisiloxane-facilitated diffusion. Data were tested for statistically significant differences by ANOVA and linear regression (p<0.05). RESULTS: Mean (± SE) plasma F concentrations ranged from 0.030 ± 0.002 to 0.187 ± 0.013 (mg/mL). The concentrations in surface and whole bone ranged from 610 ± 32 to 4,693 222; and 647 ± 22 to 3,439 ± 134 µg/g, respectively. The surface/whole F concentration ratios were 0.941, 1.414, 1.173 and 1.377, for groups 1, 2, 3 and 4 respectively. For plasma and whole bone, the difference among all groups was statistically significant, except for group 2 compared to group 1. For bone surface, all groups differed from each other except for group 2 compared to group 3. A significant positive correlation was found between bone surface and whole bone F (r²=0.94), as well as between plasma and bone surface (r²=0.71) and plasma and whole bone (r²=0.74). CONCLUSIONS: Data suggest that both bone surface and whole bone are suitable biomarkers of chronic F exposure in rats and plasma may be used as indicator of bone fluoride levels.

The injection of a low dose of eCG has the potential to induce multiple ovulation and pregnancies in cattle. The present study aimed to evaluate the ovarian response, conception rate and incidence of twin pregnancies of cyclic cows receiving 1 of 2 low doses of eCG. Multiparous Nellore (Bos t. indicus) cows with plasma progesterone levels >1 ng∙mL–1 on at least one of 2 blood samples collected at 10-day intervals (Day –10 and Day 0) received an intramuscular (IM) injection of 2 mg of oestradiol benzoate (EB; Estrogin®, AUSA, São Paulo, Brazil) and a vaginal device (DIP) containing 1 g of progesterone (Primer®, Tecnopec, São Paulo, SP, Brazil) on Day 0. On Day 8, the DIP was removed and cows received an IM injection of 150 μg of cloprostenol (Veteglan®, Hertape Calier, Juatuba, MG, Brazil). At this time, the animals were randomly distributed into 3 groups. Group 1 (n = 30) received an IM injection of 2 mL of saline, whereas groups 2 (n = 41) and 3 (n = 23) received 600 IU and 900 IU of eCG (Novormon® MSD Saude Animal, São Paulo, Brazil), respectively. Twenty-four hours later (Day 9), all groups received 1 mg of EB and were submitted to fixed-time artificial insemination (FTAI) 30 h later (i.e. 54 h after DIP removal). Oestrus observation was performed daily from the time of the withdrawal of the DIP until the day of FTAI. Ovaries were examined ultrasonically at the time of FTAI, the following day and 7 days after FTAI. Pregnancy diagnosis was done by ultrasonography 30 days after FTAI and the incidence of twin or single calves was recorded at birth. Data were analysed by chi-square test. The rate of expression of oestrus was 70.0% (group 1), 82.9% (group 2), and 78.2% (group 3; P = 0.25). Cows that had 2 or more large follicles at the time of FTAI was 0% (group 1), 14.6% (group 2), and 34.8% (group 3; P < 0.05). The ovulation rate of cows in group 1 (80.0%) was higher than cows in groups 2 (48.8%) and 3 (52.2%; P < 0.05). The conception rates for groups 1, 2, and 3 were 50.0, 26.8, and 39.1%, respectively (P < 0.05). Two animals in group 3, one in group 2, and none of group 1 had twin pregnancies on Day 30 after FTAI. Only one of these cows (group 3) had a twin calving. It was concluded that the injection of 600 or 900 IU eCG, in an oestradiol/progestogen FTAI protocol does not result in an increase in the rate of twin calvings, but may negatively affect pregnancy rates of cyclic Nellore cows.Financial support was provided by FAPESP (proc. 2011/13096–0).

Objectives: Anterior cruciate ligament (ACL) injury is a common disorder in athletes and in most cases, meniscal tears accompany. These meniscal tears can be the result of the initial trauma or the consecutive injuries in the unoperated patients. The aim of the study was to compare the incidence of meniscal tears in the patients operated because of ACL defficiency in the early or late period after the initial trauma. The age of the patient and meniscal tear pattern were the other subjects compared. Methods: The groups included 42, 72 and 129 patients respectively. Among all groups, it was shown that in 125 cases (% 51.4), a meniscal tear accompanied the ACL tear. In Group 1, 18 cases (% 42.8) had meniscal tears while 29 patients (% 37) in Group 2 and 78 patients (% 60.4) in Group 3 had any kind of meniscal tear. Bucket handle tears constituted 38 % of all tears in Group 1, 53 % in Group 2 and 56 % in Group 3. There was a significant statistical difference between the groups among the presence of meniscal tear and the period between the initial trauma and operation time. When the patients accepted the operation in the first six months after the initial trauma, the incidence of the meniscal injury decreased significantly (chi-square test) (p <0,01). There was no statistical difference between three groups among the percentage of bucket handle tears (variance analysis: p=0,196). The statistical difference was not important between the groups among the age of the patients in relation with the pattern of the meniscal tears (variance analysis: p=0,236). Results: The groups included 42, 72 and 129 patients respectively. Among all groups, it was shown that in 125 cases (% 51.4), a meniscal tear accompanied the ACL tear. In Group 1, 18 cases (% 42.8) had meniscal tears while 29 patients (% 37) in Group 2 and 78 patients (% 60.4) in Group 3 had any kind of meniscal tear. Bucket handle tears constituted 38 % of all tears in Group 1, 53 % in Group 2 and 56 % in Group 3. There was a significant statistical difference between the groups among the presence of meniscal tear and the period between the initial trauma and operation time. When the patients accepted the operation in the first six months after the initial trauma, the incidence of the meniscal injury decreased significantly (chi-square test) (p <0,01). There was no statistical difference between three groups among the percentage of bucket handle tears (variance analysis: p=0,196). The statistical difference was not important between the groups among the age of the patients in relation with the pattern of the meniscal tears (variance analysis: p=0,236) Conclusion: We can say that the incidence of meniscal tears can be decreased if the patients with ACL injury are operated early after the initial trauma. Earlier ACL reconstruction means less meniscal tear.

Introduction: Since literature provides various schools of thought to achieve Posterior Palatal Seal (PPS) in a maxillary denture, it becomes essential to know the techniques dominating in our curriculum presently. Aim: To determine the prevalence of concepts and also the need for standardisation in establishing PPS among dental colleges of Karnataka. Materials and Methods: A descriptive survey was conducted among teaching faculty of Department of Prosthodontics with varied teaching experience across the dental colleges of Karnataka. A pre-tested questionnaire containing ten close ended questions was distributed to 230 faculty members with MDS qualification in Prosthodontics via e-mail. The faculty responses were divided into three groups based on teaching experience: Group 1 (2-7 years), Group 2 (7-12 years) and Group 3 with more than 12 years of teaching experience. The Chi-Square Goodness of Fit test was used to compare the overall differences in the responses by the study participants; and Independent Chi-Square test to compare the differences in the responses based on teaching experience of the study participants. A value of p<0.05 was considered as statistically significant. Results: The most common method taught for locating vibrating line was Phonation-Nose Blowing-Fovea Palatini (46.0%). Two-line concept of vibrating line was taught (77%) more commonly, where the termination of maxillary denture is on posterior vibrating line (58%). Currently, Boucher’s conventional method without master cast scoring (63%) was the most favoured method to record the seal. This was true mainly with Group 1 (81.9%) and Group 2 (66.7%). In contrast, Group 3 faculty largely advocated Boucher’s conventional technique along with master cast scoring (70%). Overall most of the faculty members (66.5%) did not make the students score the postpalatal area. This was mainly seen in faculty belonging to Group 1 (81.9%) and Group 2 (69.7%). Bulk of Group 3 faculty (75%) taught scoring of the master cast. A large portion of the faculty (60.0%) recommended standardisation in the methods of teaching PPS which was mainly backed by Group 2 (77.3%) and Group 1 (61.7%). Conclusion: This survey indicates that among dental colleges of Karnataka, a majority of faculty of Prosthodontics prefer Boucher’s conventional method without master cast scoring (63%) to achieve maxillary PPS. Nevertheless, teaching concepts differed based on faculty experience. It is emphasised that teaching methods should be standardised and include unambiguous techniques.

Objective: To perform morphometric analysis of corpus callosum (CC) by using callosal area (CA), supratentorial-supracallosal area (SSA) and CA/SSA parameters in a healthy pediatric population and to investigate changes according to age and gender. Method: Method: This retrospective study included a total of 313 children (154 boys, 159 girls) aged between 3-17 years. The cases were divided into three groups according to age: 3-6 years (Group 1) (pre-school), 7-12 years (Group 2) (preadolescent) and 13-17 years (Group 3) (adolescent). CA and SSA were measured on the mid-sagittal plane on T1-weighted images. CA/ SSA index was calculated. Differences in age, CA, SSA, and ratio parameters among the gender groups were compared using the Mann-Whitney U or the t-test. Results: Median values of CA (p= 0.002), mean values of SSA (p=0.001) and CA/SSA ratios (p= 0.04) were significantly higher in boys compared to girls. The median CA and mean CA/SSA ratios in Group 3 were significantly higher than Groups 1 and 2 (p= 0.001). Mean CA/SSA ratio values of boys and girls in Age Group 3 were significantly higher than Group 1 (p= 0.001) and significantly higher than Age Group 2 in girls. There were highly significant positive correlations of age with CA (p=0.001, r=0.47), SSA (p=0.028, r=0.12) and CA/SSA ratio (p=0.001, r=042). There was a highly significant and positive correlation between CA and SSA (p=0.001, r=0.25) and CA/SSA ratio (p=0.001, r=0.87). Conclusion: CA, SSA, and CA/ SSA ratio values in children are affected by age and gender. These parameters can be used as reference values for the diagnosis of congenital and acquired pathologies affecting the corpus callosum.

Abstract Study question Does increasing paternal age has a negative impact in fertilization (FR), blastulation (BR), clinical pregnancy (CPR) and miscarriage (MR) rates in an egg donation program? Summary answer The increase paternal age in an egg donation program has not a negative impact in fertilization rate, blastulation rate, clinical pregnancy rates and miscarriage rates. What is known already It is well documented that semen quality is affected with increasing paternal age but there is no evidence-based definition of what is advanced paternal age. There is controversial information about if the increasing paternal age affects in vitro fertilization results, and when this negative impact could begin. Study design, size, duration This was a single center retrospective cohort study, involving 485 first single embryo transfer of an egg donation program, from January 2017 to December 2019. Participants/materials, setting, methods All first embryo transfer of egg donation cycles performed at CEGyR, Buenos Aires, Argentina were included. Elevated sperm DNA fragmentation (TUNEL &gt;20), sperm bank, and testicular biopsy cycles were excluded. Patients were divided according to male partner age: (1) &lt;41, (2) 41–44, (3) 45–50 and (4) &gt;50 years old. Group (1) was considered the control group. Statistical analyses were performed for FR and BR with ANOVA and CPR and MR with chi-squared tests. Main results and the role of chance The number of patients in group (1) was 200, in (2) 130, in (3) 117 and in (4) 38. Male average age was 36,8 in group (1), 42,2 in (2) 47,1 in (3) and 54,2 in group (4). The FR in group (1) was 72,60%, in group (2) was 73%, in (3) was 75% and 73% in (4). ANOVA results for FR: F = 0,65 (p: 0,58). The BR, defined as the relation between the total number of blastocysts over the number of fertilized oocytes in a cycle, was in group (1) 46,35%, in group (2) was 45%, in group (3) 46%, and in group (4) 42%. ANOVA results for BR F = 0,36 (p:0,78). The CPR in group (1) was 42,19%. Comparing with the other groups: group (2) was 37,09% (chi-square statistic=0,64 p:0,43); group (3) 34,58% (2,32 p:0,13); and group (4) was 32,43% (1,48 p:0,22). The MR in group (1) was 12,49%. Comparing with the other groups: group (2) was 18,55% (chi-square statistic=2,31 p:0,12); group (3) 14,94% (1,01 p:0,32); and group (4) was 15,85% (0,91 p:0,33). For all results analyzed there were not a statistically difference between groups. Limitations, reasons for caution The main limitation of this study was its retrospective design based on data from a single center which may be subject of bias. Wider implications of the findings: Further large prospective studies are required to make meaningful comparisons. Our findings give no support for a general recommendation.

BACKGROUND: There remains controversy regarding the outcomes resulting from treatment versus conservative management of patent ductus arteriosus (PDA) among preterm infants. The effects of extreme prematurity, hemodynamic status of the PDA, and age at treatment remain poorly defined. STUDY DESIGN: This retrospective case-control study including infants <  1250 gm who were categorized into 3 groups: Group 1: without PDA, Group 2: with untreated PDA, and Group 3: treated PDA. Diagnosis and treatment of PDA extracted from the medical records. Demographics, clinical characteristics, and outcomes compared using chi-square and analysis of variance. Logistic regression used to estimate adjusted odds ratios. RESULTS: The study included 734 infants, with 141(19%) in Group 1, 329 (45%) in 2, and 264 (36%) in 3. Group 3 had higher incidence of bronchopulmonary dysplasia (BPD) (aOR, 2.9; 95%CI 1.7–4.8). Infant treated for hemodynamically significant PDA (HSPDA) had higher incidence of BPD (aOR, 1.9; 95%CI 1.0–3.8) and retinopathy of prematurity (ROP) (aOR, 3.4; 95%CI 1.6–6.9). There were no differences in outcome associated with treatment among≤26 weeks gestation and the age when treated. CONCLUSION: Infants with PDA who were treated had higher incidence of BPD. Among those who were treated, those with HSPDA had a higher incidence of BPD and ROP.

ABSTRACT Objectives: To investigate occlusal stability from the early mixed to the permanent dentition in children after early treatment with the eruption guidance appliance (EGA). Materials and Methods: Of 46 participants who received 1-year early EGA treatment, 35 attended a follow-up examination at age 12. Group 1 (n = 21) started their EGA treatment at mean age 7.7 years, and group 2 at 9.1 years. Following 1-year treatment, the EGA was used as a retainer. Changes in overjet, overbite, sagittal molar relationship, and anterior crowding were measured on casts obtained before EGA treatment, after EGA treatment, and at follow-up to evaluate occlusal stability. Results: Mean overjet, overbite, sagittal molar relation, and mandibular crowding improved significantly during the study period. Participants with good compliance during the retention period had significantly smaller overjet and overbite values than those with poor compliance. Conclusions: Early correction of increased overjet, overbite, and class II molar relation with the EGA is maintainable and can also be effective in the permanent dentition, provided the EGA is worn regularly as a retainer.

Objective: To determine the maximum occlusal bite force (MOBF) of the complete spectrum of dental caries in first permanent molars (FPMs) in children aged 7–9 years. Study design: A cross-sectional study was conducted on 123 children. The evaluation of the caries spectrum of FPMs was carried out using the Caries Assessment Spectrum and Treatment index (CAST). The MOBF was measured in the FPM region using the portable occlusal force gauze. Independent sample t-test and one-way analysis of variance test were performed to compare MOBF with CAST scores of FPMs. Based on the CAST scores, FPMs were categorized into three groups, group 1: healthy (score 0, 1, 2), group 2: premorbid (score 3), group 3: morbid (score 4, 5). Results: A significantly lower MOBF was observed (167.56 N ± 49.77) in the morbid stage (group 3) than in the premorbid stage (group 2: 291.57 N ± 56.64), and healthy (group 1; 320.93 N ± 54.23). Intergroup comparison also revealed that FPMs in the healthy stage was associated with a higher bite force compared to those in the premorbid and morbid stages (p&lt;0.001). Conclusions: The mean MOBF decreased with the progression of the caries spectrum of FPMs in early permanent dentition.

Objective. The aim of this study was to evaluate and compare, both clinically and radiographically, the effects of calcium silicate-based materials (i.e., ProRoot MTA [PR-MTA], MTA-Plus [MTA-P], and Biodentine [BD]) and ferric sulfate [FS] in pulpotomy of primary molars. Materials and Methods. In this randomized clinical trial, 29 healthy 5- to 7-year-old children with at least four carious primary molars with no clinical or radiographic evidence of pulp degeneration were enrolled. The pulpotomy agents were assigned as follows: Group 1: BD; Group 2: MTA-P; Group 3: PR-MTA; and Group 4: FS. Clinical and radiographic evaluations were performed at 6, 12, and 24 months. Data were analyzed using chi-square tests. Results. Total success rates at 24 months were 82.75%, 86.2%, 93.1%, and 75.86%, respectively. No statistically significant differences in total success rates were observed among the groups at 6-, 12-, and 24-month follow-ups. When the groups were compared according to follow-up times, the success rates in each group did not vary significantly among the 6–12-month, 6–24-month, or 12–24-month periods (p>0.05). Conclusion. Although the success rates of BD, MTA-P, MTA-PR, and FS did not differ significantly, calcium silicate-based materials appeared to be more appropriate than FS in clinical practice.
