Staphylococci are considered members of the transient oral microbiota and are seldom isolated from the oral cavity. The aim of this study was to establish the prevalence of subgingival staphylococci in healthy and periodontal disease sites. Sterile endodontic paper points were used to isolate subgingival staphylococci in periodontally healthy and periodontally diseased sites in 30 adult subjects (n=540 sites). Staphylococcus spp were identified by an automated method and confirmed by conventional biochemical tests. All the samples were identified as coagulase-negative staphylococci. The results were analyzed using Mann-Whitney U, chi-square and Fisher's exact test at 5% significance level. A total of 86.7% of the subjects harbored these microorganisms in 11.7% of their periodontal sites. The most frequently isolated species was S. auricularis, which was isolated from 31.4% of the periodontal sites, followed by S. epidermidis, isolated from 21.4% of them. There was no statistically significant difference between the frequencies of these species isolated either from the healthy and the diseased sites (p>0.153). Although staphylococci are present in the subgingival environment and contribute to the pathogenic synergism involved in periodontal diseases, the results suggest that they do not participate directly in the pathogenesis of these diseases.

Abstract Introduction Tooth agenesis is likely to affect the root teeth and should be considerated in orthodontic tratament. Objective The aim of this study was to assess the association between agenesis and root morphology of anterior teeth. Material and method The anterior teeth of 51 individuals were evaluated on 102 periapical radiographs and then divided into three groups: Group 1 (n=16) – no tooth agenesis; Group 2 (n=17) – only third molar agenesis; and Group 3 (n=18) – tooth agenesis of premolars or lateral incisors. Root morphology of anterior teeth was evaluated and the roots were classified as short, blunt, apically bent, and pipette-shaped. Fisher’s exact test was used to compare root shapes, the chi-square test was used to obtain the distribution of sexes between the groups, and ANOVA was performed to compare the ages between the groups. The significance level was set at 5% for all analyses. Result There was significant difference in root shapes (P<0.05) between the groups. Blunt roots were the most prevalent in all groups, but their rate was higher in Group 3 (83%). Conclusion There was association between agenesis and root morphology of anterior teeth.

Objective: the purpose of this study was to evaluate and compare, gross fracture, patient satisfaction, and marginal adaptation of anterior endocrowns restoring endodontically treated anterior teeth fabricated from IPS e.max press and CERASMART hybrid ceramics. Material and methods: A total of 24 patients were selected to receive an esthetic endocrowns for upper teeth in the esthetic zone (central incisor, lateral and canine).The 24 patients were divided into 2 groups (n=12 each), where Group (1): Control group: Teeth receiving IPS e.max press anterior endocrowns and Group (2): Intervention group: Tooth receiving CERASMART anterior endocrowns . After cementation all patients were recalled after 3, 6, 9, and 12 months. During each recall examination, USPHS criteria were adopted for clinical evaluation to score margin integrity and gross fracture. In addition, questionnaires were used to evaluate patients’ satisfaction and potential postoperative discomfort. Chi-square or Fisher’s Exact test were used to compare between qualitative variables in the two groups. Friedman’s test was used to study the changes by time within each group. The significance level was set at P ? 0.05. Results: Regarding gross fracture and marginal integrity, there was no statistically significant difference at any time interval between IPS e.max press and CERASMART endocrowns. All the patients were satisfied with their restorations till the end of the follow up period. Conclusions: CERASMART anterior endocrowns provided a promising treatment modality compared to ips press anterior endocrowns.

Objective: Constipation is one of the most common problems of the elderly, causing many complications and high costs for these individuals and affecting their quality of life. This study aimed to compare the effect of Golghand (a pharmaceutical composition of roses and honey) and foot reflexology on constipation in the elderly. Methods: This clinical trial was conducted on 60 elderly people with constipation in 2017. Subjects were selected through simple and purposive sampling and were randomly allocated to Golghand and foot reflexology groups by permuted block method. The foot reflexology was carried out in the specific area of constipation twice a day and each time for 15 minutes for two weeks. Golghand group received Golghand half an hour before lunch (one teaspoon of Golghand in one cup of cooled boiled water). Constipation assessment scale was filled for the subjects before and at the end of the intervention by an evaluator, who was unaware of the intervention approaches of the groups. Data analysis was performed in SPSS version 20 using statistical tests of Chi-square, Fisher’s exact test, Mann-Whitney U, and Friedman test at the significance level of <0.05. Results: In this research, mean age of the participants was 66±8.66 years. According to the results of Mann-Whitney U, no significant difference was observed between the groups in terms of the frequency of bowel movements on the first day after intervention (P=0.246). However, on days 2-14 after the intervention, a significant difference was observed between the study groups in this regard (P<0.05). Similarly, results of the Friedman test were indicative of a significant difference between the two groups regarding the frequency of bowel movements (P<0.001), in a way, that after the passing of the mean period, the number of bowel movements increased in both groups. However, this increase was higher in the Golghand group, compared to the foot reflexology group (P<0.001). Moreover, independent t-test demonstrated a statistically significant difference between the groups regarding mean intensity of constipation (P=0.01). Conclusion: Consumption of Golghand increased the frequency of bowel movements and reduced the intensity of constipation in elderly individuals. This method had greater impacts on constipation, compared to the foot reflexology technique.

Abstract Objectives: to investigate the prevalence of alcohol consumption during pregnancy and its sociodemographic, reproductive and newborn-related factors. Methods: a cross-sectional and exploratory study carried out on a sample of post-partum women, recruited daily over six months. Sociodemographic and reproductive information about the women and data concerning the newborns were collected. T-ACE questionnaire was used to identify the pattern of alcohol consumption by the women. They were divided into two groups: alcohol consumers (T-ACE score ≥2) and non-alcohol consumers. Comparisons between the two groups were made using the unpaired t test, chi-square test or Fisher's exact test according to the type of variable analyzed. The significance level was set at 5%. Results: out of 925 women, 818 (88.4%) agreed to participate. Among them, 60 (7.3%) were T-ACE positive, i.e. identified as alcohol consumers. Regarding the sociodemographic information, alcohol consumption was more frequent among women who did not have a steady partner (p=0.010). No reproductive variable presented a significant difference between the groups. A lower weight was observed among children of T-ACE positive mothers (3,045g±71.0 vs 3,192g±19.2; p=0.040). Conclusions: identifying and characterizing women who are more susceptible to alcohol consumption during pregnancy can contribute to developing more effective public health intervention strategies.

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.

Background: Infertility can cause low marital satisfaction. Marital satisfaction has an important effect on infertile couples’ health. Objective: This study aimed to assess the effect of relationship enrichment training on improving the marital satisfaction of infertile couples. Methods: This randomized clinical trial was conducted on 50 infertile couples in the infertility center of Fatemieh Hospital in Hamadan, Iran in 2018. Participants were matched for demographic characteristics and randomly assigned to intervention and control groups (each group had 25 couples). Informed consent was obtained from all participants. The Enrich Marital Satisfaction questionnaire and demographic information were used to collect data before the study and two months after the intervention. Two trained midwifery students taught only the intervention group the relationship enrichment topics in seven sessions (each session = 90 minutes). The data were analyzed by SPSS Statistics version 21 using analysis of covariance, independent t-test, chi-square, and Mann–Whitney. The significance level was set at p ≤ 0.05. Results: There was no significant difference in demographic and obstetric information between the two groups (p >0.05). The mean of marital satisfaction in the intervention group significantly increased among women and men from 151.00 ±28.61 to 154.88 ±22.62 and from 152.56 ±27.33 to 159.24 ±22.14, respectively, (p <0.001). Conversely, the mean of marital satisfaction decreased among women and men from 158.13 ±13.86 to 146.25 ±19.53 and from 164.25 ±17.00 to 153.17 ±27.50 in the control group (p=0.02). Conclusion: Relationship enrichment training can be effective in promoting the marital satisfaction of infertile couples.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p &lt; 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p&gt;0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

Skeletal Asymmetry

ABSTRACT Introduction: Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. Objective: The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate its association with posterior tooth absences. Methods: Tomographic images of 952 individuals aged from 18 to 75 years old were used. Asymmetry was the analyzed outcome, and it was categorized into three groups according to gnathion displacement in relation to the midsagittal plane (relative symmetry, moderate asymmetry, and severe asymmetry). Patients were sorted by the presence of all posterior teeth, unilateral posterior tooth absence, or bilateral posterior tooth absence. Chi-square test with a significance level of 5% was used to verify the association between posterior tooth absence and asymmetry. Results: Results show relative symmetry present in 55.3% of the sample, as well as the prevalence of 27.3% for moderate mandibular asymmetry and 17.4% for severe asymmetry. Moderate and severe mandibular asymmetries occurred in a higher proportion in patients with unilateral posterior tooth absence. However, there was no statistically significant difference between the analyzed groups (p = 0.691). Conclusions: In this study, mandibular asymmetries did not present any association with the absence of teeth on the posterior area of the arch.

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.
