Effectiveness of Calcium Hydroxide and Gingerols Mixture as a Novel Obturation Material for Infected Root in Primary Teeth: A Randomized Clinical Trial.

Introduction: The tendency to use dental materials of plant origin is one of the prevailing trends in dentistry to reduce exposure to materials that could have some toxic impact in the long term. Objective: To evaluate the efficacy of calcium hydroxide combined with gingerols (Ginge-Cal) as a novel obturation material for treating infected primary teeth and decreasing the recurrence of infection. Materials and Methods: The study was conducted on 30 lower primary molars with infected pulp for children aged 4-8 years. The sample was randomly divided into two groups depending on the tested obturation material: Ginge-Cal group and the Metapex group. The evaluation was done by different parameters clinically and radiographically at various intervals up to 12 months. Results: Based on chi-squared and McNamara's test with a 5% significance level, the clinical results indicated that Ginge-Cal group was more effective than the Metapex group in reducing or eliminating pain (P=0.467) after 1 week, sensitivity to percussion (P=0.090) at 3 months of follow-up, purulent swelling (P=0.444) at 6 and 9 months of follow-up, fistula, and tooth mobility. The radiographic results, based on the periapical and furcation area radiolucency at 12 months of follow-up, favored Ginge-Cal group over the Metapex group (P=0.683), (P=0.456), respectively. There were no statistically significant differences in pathological root resorption and periodontal space. The differences within the Ginge-Cal group were directly influenced by the time intervals in a statistically significant manner, ranging from (P=0.004) to (P < 0.001). The success percentage was 87.5% for Ginge-Cal group and 64.3% for Metapex group. Conclusions: Ginge-Cal can be considered a promising material for treating the infected root canal when used as an obturation material for the infected root canal. This trial is registered with NCT05181813.

Colonic medullary carcinoma: an exceedingly rare type of colorectal malignancy: a case report and review of the literature.

BACKGROUND: Medullary carcinoma of the colon is a rare subtype of colorectal cancer that has a unique, and sometimes varied, clinical and histologic profile. It usually presents in adult patients older than 50 years. Here, we report a unique case of young male patient who initially presented with abdominal pain followed by a large bowel obstruction. CASE PRESENTATION: A 40-year-old SriLankan male presented with right-sided abdominal pain and on examination, there was a palpable right iliac fossa mass. Colonoscopy and a computed tomography scan revealed cecal mass. Later, while waiting for elective resection, the patient developed symptoms and signs of a large bowel obstruction. He underwent a laparoscopic right hemicolectomy with an uneventful postoperative course. The histopathologic evaluation of the resected specimens showed invasive carcinoma with syncytial growth pattern, foci of lymphoid host response, and dirty necrosis, in keeping with a medullary carcinoma pT4a pN2b. Unlike most reported medullary carcinoma cases, this patient was young and caudal-related homeobox transcription factor 2 positive. CONCLUSION: We have reported another case of medullary carcinoma of the colon in a young patient with unique histologic characteristics. Reporting such cases helps in refine understanding of the histologic and genetic, as well as clinical, phenotypes of medullary carcinoma of the colon.

Moderating Effects of Self-Esteem on the Relationship between Communication Anxiety and Academic Performance among Female Health College Students during the COVID-19 Pandemic.

Unprecedented quarantine due to COVID-19 exposes individuals to withdraw from face-to-face interactions, which may influence communication and self-esteem (SE). Therefore, the overarching aims of this study are to examine the communication apprehension levels among female college students, and thus to investigate the moderating role of self-esteem on the relationship between communication apprehension and academic achievement. In this cross-sectional study, 287 female college students completed the survey, which was circulated through email. The survey included the following questionnaires: General Health Characteristics, Rosenberg Self-esteem Scale, and Personal Report of Communication Apprehension Scale. The results showed that 28.2% of participants were categorized as having a high level of communication apprehension, and only 9.8% had a low level of communication apprehension. The SE reported an overall score of 24.3 ± 2.14, indicating a high self-esteem level among students. The students' grade point average (GPA) was positively correlated with SE. However, self-esteem as a moderator variable had no significant effect on the relationships between all predictors and GPA. The finding of the study highlights the need to implement different strategies to enhance students' group discussions, meetings, and interpersonal communication to ensure the best learning outcomes. Future studies are required to investigate gender-based disparities in the relationship between communication apprehension and SE.

Comparison of Clinical Outcomes of Silver-modified Atraumatic Restorative Technique vs Atraumatic Restorative Technique in Primary Teeth: A Randomized Controlled Trial.

AIM: To compare the clinical outcomes of silver-modified atraumatic restorative technique (SMART) vs atraumatic restorative technique (ART) in primary teeth. MATERIALS AND METHODS: This study was a randomized clinical trial conducted on 30 children. The study was split-mouth design, so each group was consisted of 30 children. Children aged 3-6 years old of both genders. Communication with the children was established. Gross debris from cavitation was removed. Carious dentin on walls was excavated using spoon excavator and low-speed contra with round or fissure bur. The areas to be treated were isolated with cotton rolls. For ART, glass ionomer cement (GIC) was applied according to the manufacturer's instructions. For silver-modified atraumatic restorative technique (SMART), a protective coating was applied to the lips and skin to prevent a temporary tattoo. Silver diamine fluoride (SDF) was applied carefully using bended microsponge brush. It was applied directly to only the affected tooth surface. The lesion was dried for 15 seconds with gentle flow of compressed air. After 1 week, GIC was applied according to the manufacturer's instructions. Clinical evaluation was done for all teeth at 6 and 12 months. The data were collected and then statistically analyzed using the Chi-square test to show the difference between groups. RESULTS: The restoration of the first primary molar with ART restoration alone showed a lower success rate when compared with the restoration with a combination of SDF and ART (SMART technique), with percentages of 70% and 76.67% and 53.33% and 60% after 6 months and 12 months of follow-up, respectively. CONCLUSION: Silver diamine fluoride is successful in arresting dentin caries and can be used to increase the efficacy of the ART technique in primary teeth. CLINICAL SIGNIFICANCE: It is recommended to use SDF as a noninvasive approach to control dentin caries with the ART technique.

Effect of Resilience on Health-Related Quality of Life during the COVID-19 Pandemic: A Cross-Sectional Study.

The unprecedented outbreak of coronavirus disease 2019 (COVID-19) has caused a huge global health and economic crisis. The aim of the study was to examine the extent to which the resilience of a person is associated with the quality of life (QoL) of adults amongst Saudi Arabia. A cross-sectional study was conducted among a sample of adults in Saudi Arabia. A total of 385 adults voluntarily participated in and completed the survey. The quality of life was measured using the "World Health Organization QoL". The "Connor-Davidson Resilience Scale" instrument was also used to assess resilience during the COVID-19 pandemic. Amongst the 385 participants, 179 (46%) showed a good QoL, and 205 (54%) reported a relatively poor QoL. The resilience was found to be significantly associated with QoL. The study further revealed that gender-based differences were dominant in the QoL; the men respondents reported a significantly higher QoL in all the domains in comparison to the women respondents. The gender, income, and psychological health and interaction effect of resilience and age explained 40% of the variance in the total score of QoL. In reference to the predictors of the physical health domain of QoL, resilience, gender, and psychological health were significantly associated with the physical health domain of the QoL (R2 = 0.26, p = 0.001). It was also noted that gender was not associated with the social relationships and environmental domains of QoL (p > 0.05). Findings showed a statistically significant association between the score of QoL and resilience, age, gender, income, and psychological health. These findings highlight the significant contribution of gender-based differences, psychological health, and resilience on the domains of QoL.

Quality of Life, Needs and Fears of Mothers of Children with Disabilities in Saudi Arabia during the COVID-19 Lockdown.

Substantial changes in life dynamics resulting from the outbreak of the coronavirus disease 2019 (COVID-19) could have an impact on the quality of life (QoL) of mothers of children with and without disabilities. This study compared the quality of life (QoL) of mothers of children with disabilities (MCD) to the QoL of mothers of children without disabilities (CON) in Saudi Arabia during COVID-19 lockdown. It explored mothers' concerns and the type of support they need during the quarantine. A comparative cross-sectional study was conducted during the lockdown. An online questionnaire was distributed to mothers raising children with and without disabilities in Saudi Arabia. A total of 340 mothers participated in the study by completing the survey: 93 MCD and 247 CON. The QoL of MCD and CON was assessed using the WHOQOL-BREF questionnaire. Furthermore, detailed information was provided by the mothers regarding their needs and concerns during the lockdown. The results of the study revealed that the overall QoL was significantly higher in the CON group, compared to the MCD group, during the COVID-19 lockdown. The social well-being and environmental well-being reported by MCD were significantly lower on the total scale of the WHOQOL-BREF than those reported by the CON group. The comparison between the two groups revealed significant differences in the support required by mothers during the COVID-19 pandemic: a higher percentage of MCD needed emotional and psychological support, especially from family members. The major concerns reported by MCD were the deterioration of their children's medical conditions and the lack of medical supplies during the lockdown.

Influence of pulpotomy medicaments on the ultrastructure and shear bond strength of a self-etch adhesive to primary tooth dentin.

OBJECTIVE: To compare the effect of the pulpotomy medicaments glutaraldehyde, ferric sulfate, and formocresol on the structure and shear bond strength of a self-etch adhesive to the dentin of primary teeth. METHOD AND MATERIALS: Forty human primary molars were sectioned mesiodistally and divided into four groups: group I (control group), dentin specimens were soaked in distilled water for 48 hours; group II, dentin specimens were soaked in 2% glutaraldehyde; group III, dentin specimens were soaked in formocresol; and group IV, dentin specimens were soaked in 15.5% ferric sulfate. All specimens were rinsed with tap water and dried with air. AdheSE One (a self-etch adhesive) and Valux Plus composite resin were applied to the dentin surfaces. The molecular structure of the adhesive itself and adhesive with composite resin were tested using an FTIR spectrometer. Shear bond strength was tested with a universal testing machine. Failure modes analyses were performed with a scanning electron microscope (SEM). RESULTS: Glutaraldehyde showed little changes in the molecular structure of the adhesive itself and adhesive with composite. However, ferric sulfate and formocresol affected the molecular structure of the adhesive alone and the adhesive with composite. The highest mean value of shear bond strength was for the glutaraldehyde group (11.17 ± 4.87 MPa). Ferric sulfate and formocresol significantly reduced shear bond strength after the application of pulpotomy medicaments (7.45 ± 3.73 and 5.31 ± 3.30 MPa, respectively). SEM analysis revealed that most of the specimens failed in cohesive and mixed modes. CONCLUSION: This study revealed that formocresol and ferric sulfate adversely affect the shear bond strength and molecular structure of the adhesive system to primary dentin.

Complaints of the arm, neck and shoulder among computer office workers in Sudan: a prevalence study with validation of an Arabic risk factors questionnaire.

BACKGROUND: Complaints of the arm, neck and/or shoulders (CANS) in general and computer-related disorders in particular affect millions of computer office workers in Western developed countries. However, with the widespread use of computer systems in developing countries, the associated musculoskeletal complaints are yet to be investigated. AIM: To study the prevalence of work-related CANS, among computer office workers in Sudan, and to test the psychometric properties of a translated Dutch questionnaire in Arabic language. METHODS: In 2005 282 computer office workers at a mobile telecommunication company and three banks in Khartoum, Sudan, received an Arabic language version of the validated Maastricht upper extremity questionnaire (MUEQ). The questionnaire holds 109 items covering demographic characteristics, in addition to six main domains (i.e. work station, body posture, break time, job control, job demands and social support) assessing potential physical and psychosocial risk factors. Forward/backward translation of the MUQE was done independently by two different translators. Prevalence over the past year were computed for CANS. Further, the psychometric properties of the Arabic questionnaire were investigated (i.e. factor structure and reliability) and cross-validation was carried out. RESULTS: The response rate of the questionnaire was 88% (n = 250). The one-year prevalence of CANS showed that 53% of the respondents could be classified as mild cases. The highest incidences were found for neck and shoulder symptoms (64% and 41% respectively). The analysis of the psychometric properties of the scale resulted in the identification of 2 factors for each of the 6 domains (i.e. office equipment, computer position, head and body posture, awkward body posture, autonomy, quality of break time, skill discretion, decision authority, time pressure, task complexity, social support, and work flow). The calculation of internal consistency and cross validation provided evidence of reliability and lack of redundancy of items. CONCLUSION: The prevalence of CANS among the targeted population seems to correspond strongly with prevalence of CANS in Western developed countries. The Arabic translation of the MUEQ has satisfactory psychometric properties to be used to assess work-related risk factors for the development of CANS among computer office workers in Sudan.
