This study aimed to investigate burnout and its relationship with spiritual intelligence in Mashhad Dental School residents in 2019-2018. Methods: In this cross-sectional descriptive-analytical study, approximately all the dental residents of Mashhad Dental School participated in the survey. Demographic information questionnaire, Maslach burnout questionnaire, and David B. King’s (2008) Spiritual Intelligence Scale were used to collect data. Finally, SPSS software (version 20) was employed for data analysis. Results: Overall, 53 women (52%) and 49 men (48%) with a mean age of 27.83 years participated in this study (a response rate of 97%). The mean score of burnout was 58.75. Residents also had a low reduced personal accomplishment, moderate emotional fatigue, and moderate depersonalization. The mean scores of spiritual intelligence and its sub-scales, including critical existential thinking, production of personal meaning, awareness transcendence, and consciousness expansion were 51.91, 15.66, 13.19, and 14.67, respectively. Personal accomplishment was significantly correlated with overall spiritual intelligence (P<0.001, r=0.404) and its sub-scales, including producing personal meaning (P=0.009, r=0.26), transcendental awareness (P<0.001, r=0.382) critical thinking (P=0.04, r=0.2), and conscious state expansion (P<0.001, r=0.356). Eventually, there was no significant difference between burnout and spiritual intelligence and their sub-scales regarding gender, marital status, and school year (P<0.05). Conclusions: Mashhad Dental residents showed moderate levels of emotional fatigue and spiritual intelligence. Accordingly, there is a need for planning strategies to reduce burnout.","PeriodicalId":8679,"journal":{"name":"Avicenna Journal of Dental Research","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84800560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the present study aimed at evaluating the effect of using diode low-power laser irradiation (photobiomodulation) on the amount of pain, swelling, and trismus due to latent mandibular third molar surgery (surgical removal of latent mandibular third molars). Methods: In this double-blind randomized clinical trial study, 16 individuals with latent mandibular third molars with an identical condition were selected. The teeth were randomly assigned to two groups of laser irradiated intervention group and a non-irradiated control group. A 940 nm diode laser with an output power of 200 mW and an energy density of 12 J/cm2 was applied for 60 seconds at a distance of 1 cm three intraoral points and an extraoral point. The distance between incisal edges of upper and lower central teeth, the horizontal distance between corners of lips and auricle (LE), the vertical distance between the outer canthus of the eye and the mandibular angle (EA), and pain visual analogue scale were measured before surgery and two and seven days after surgery. Results: There was no statistically significant difference between the two groups regarding EA and LE before intervention and on days 2 and 7 after intervention (P>0.05). However, the pain score was significantly higher before intervention (3.31±0.7 vs. 2.38±0.8, P=0.001) and on day 2 after intervention (6.5±1.32 vs. 4.5±0.97, P<0.001) in the control group. On day 7, a higher maximum jaw opening (MJO) was observed in the intervention group (40.68±5.76 vs. 36.81±4.35, P=0.04).

A 69-year-old man was admitted due to the recurrence of the lesions in the forehead and scalp area, and he underwent surgery again one year ago. On initial examination, a lesion sized 5 cm× 5cm with an indistinct margin was visible in the frontal region. The lesion had bleeding, itching, and purulent discharge. Computed tomography scan results indicated skull bone resorption, and pathologic report showed active ulcer BCC with infiltrative growth pattern widely disseminated in deep portion. Tumor size was 4.5 cm × 4.3 cm × 1.5 cm and was negative for lymphovascular invasion. The patient was organized for wide local excision of the lesion. Following the tumor resection, the remaining oval defect was reconstructed using the pinwheel flap under general anesthesia in the operating room.

Showcasing a high mortality rate, cytokine storm is identified as one of the most common culprits for death in affected individuals. In patients undergoing severe complications in the form of intubations and intensive care unit (ICU) admissions, increased cytokine levels have again been identified as a significant factor, indicating their substantial role in disease outcomes. Periodontitis, which is identified as a silent pandemic, is the most common oral disease that is found in individuals. The increased accumulations of plaques and calculus are the main causative agents, stimulating inflammatory cells in the periodontal tissue, leading to cytokine release. Individuals with the removable or fixed dental prosthesis are at increased risk of contracting fungal infections, which are also identified as increasing the cytokine levels and worsening an individual’s condition contracted with COVID-19. This review focuses on oral hygiene measures and scientifically proven aids that can be used by patients at home for reducing oral cytokine levels and the risk of COVID-19 related complications, thereby sensitizing them at a time when elective dental procedures are discouraged and patients are devoid of professional dental intervention. Mechanical removal of plaques and calculus cannot be substituted with auxiliary aids, but it is important that adjunct practices be adopted for efficient hygiene. Toothbrush hygiene should also be practiced to prevent disease progression and transmission. Adherence to these recommendations is not only required for healthy or infected individuals but also for viral infection recovered patients to avoid the possible risk of developing the black fungus infection.","PeriodicalId":8679,"journal":{"name":"Avicenna Journal of Dental Research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73018943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As compared to the beginning of dental operations, the total microbial load suspended in the air rises more than three times during dental procedures due to the aerosols contained in the saliva, blood, organic tooth particles, bacteria, or viruses. Various types of dental lasers are recognized to be already produced and used in the treatment of hard and soft dental and oral tissues. One of the benefits of the dental laser is its ability to decontaminate surfaces and destroy germs. Dental lasers produce substantially less aerosols and droplets in comparison to high-speed dental headpieces and ultrasonic devices. Therefore, it is beneficial to indicate its influence in reducing the COVID-19 contamination risk, especially in dentistry.","PeriodicalId":8679,"journal":{"name":"Avicenna Journal of Dental Research","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83864442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the lack of sufficient information about the application of the Er, Cr:YSGG laser, the present study was conducted to compare the degree of enamel color changes after teeth bleaching treatment using chemical whitening agents alone and with Er, Cr:YSGG laser. Methods: In this laboratory study, several human molars were cut into 4 parts after cutting and removing the pulp. Based on laser application, the samples were randomly divided into two groups (N=20), including the chemical bleaching group (G1) and the chemical bleaching group with activated laser (G2). In G1, the bleaching process was performed only with 35% hydrogen peroxide for two weeks (3 times, 15 minutes each week). In G2, the gel bleaching was activated by the Er, Cr:YSGG laser with a wavelength of 2780 nm. It was placed 2.5 cm from the sample surface with bleaching agents and applied twice for 15 seconds. Color changes were recorded using a spectrophotometer before bleaching, immediately after, 1 month, and 3 months after bleaching. Data were analyzed by SPSS software (version 18), Repeated measures ANOVA, and Tukey’s tests (α=0.05). Results: Mean and standard deviation of changes in Δa showed a significant difference between the gel group and the gel group with laser over time (P<0.05), but this difference was not observed in ΔL and ΔB (P>0.05). However, the intragroup comparison demonstrated significant changes in Δa and Δb in both groups over time, but not in ΔL (P>0.05). The ΔE changes in both the laser and bleaching gel groups were above the threshold of 3.3. The results indicated no significant difference between G1 and G2 in terms of the ΔE (P>0.05). Finally, the results revealed that 1 and 3 months after teeth whitening, ΔE changes in both groups were greater than 3.3. Conclusions: Overall, the application of the Er, Cr:YSGG laser had no positive effect on bleaching efficacy when using a 35% hydrogen peroxide gel. Based on the findings, color changes were stable in the studied groups for up to 3 months after teeth bleaching.","PeriodicalId":8679,"journal":{"name":"Avicenna Journal of Dental Research","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86964849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neoplasia in squamous cells is a subtype of carcinoma which can cause squamous cell carcinoma (SCC). SCC can occur in several areas in the oral cavity (oral squamous cell carcinoma, OSCC) and cutaneous tissues (cutaneous squamous cell carcinoma, CSCC) such as skin. This study aims to investigate the expression level of cyclin D1 and its relevance to different prognoses of OSCC and CSCC. The present study investigates the expression of cyclin D1 and its relevance to different prognoses of OSCC and CSCC. Indexes such as lesion site, gender, and age have been checked. Methods: In this cross-sectional descriptive-analytical study, 23 cases of OSCC and 23 cases of CSCC were evaluated. The immunohistochemistry (IHC) staining method was employed to study the correlation of cyclin D1 and the above-mentioned SCCs. The data were analyzed using KAI2, Fisher’s exact test, Mann-Whitney U test, and dependent t tests in SPSS version 22.0. Statistical significance was set at P<0.05. Results: The results showed that staining status was not significantly correlated with lesion site (P=0.999). According to the results, there was no significant relationship between staining pattern and lesion site (P=0.749). There was a significant relationship between the severity of staining and lesion site (P=0.040). In addition, those with skin lesions showed higher staining intensity. The staining status of gender or age groups was not affected by the adjustment of lesion site. By moderating the effect of lesion site and age group, gender was found to affect staining pattern (P=0.036). The odds ratio of having a diffuse pattern was 4.90 times higher in men than in women. Regardless of the independent variables in the model of people with color intensity 2, their likelihood of going to color 4 was significantly higher (P<0.001). People in intensity 0 were significantly less likely to go to 4 (P=0.001). People in intensity 1 had no significant relationship with those in intensity 4 (P=0.405). Men were less likely to go higher than women. Furthermore, people aged 72 and under were less likely to go higher. Individuals with skin lesions were more likely to go to higher intensity, even though none of the independent variables was significant. Conclusions: The staining intensity was higher in CSCC than in OSCC. A lot of factors are associated with the prognosis of SCCs, and cyclin D1 may be used as a prognostic marker.","PeriodicalId":8679,"journal":{"name":"Avicenna Journal of Dental Research","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78409766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine the relationship between frontal sinus (FS) morphology and cervical vertebral maturation (CVM) to predict the skeletal maturity of an individual. Methods: The present study consisted of 252 lateral cephalograms of orthodontic patients. CVM stages and FS parameters such as FS height, FS width, and FS index were assessed using the same lateral cephalogram. Statistical methods including t test, analysis of variance (ANOVA), and Pearson correlation (r) were used for the statistical analysis. Results: FS height and width were greater in males (24.33±4.21; 10.08±3.20) compared to females (21.43±5.34; 8.12±2.19), indicating a statistical difference (P<0.05). However, FS index did not show a statistically significant difference (P=0.32) between males (2.59±0.74) and females (2.69±0.44) (P=0.32). FS height and width increased significantly in a linear fashion from CVM stage 1 to stage 6. FS index, on the other hand, did not exhibit any statistically significant differences among CVM stages in both males and females. FS height and width showed a significant weak to moderate correlation with CVM stages in both males and females. However, FS index exhibited a mild and weak negative correlation with the CVM stages in both males and females. Conclusions: FS height and width had a significant weak to moderate correlation with CVM stages in both the males and females, while FS index had a weak negative correlation with CVM stages in both males and females. Unlike the CVM method, the FS morphology cannot be reliably utilized to assess the skeletal maturity.","PeriodicalId":8679,"journal":{"name":"Avicenna Journal of Dental Research","volume":"54 93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80603534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
