RESUMEN
Objective: Congenital fusion of jaws is a rare disorder which is observed in infants and cab ne syndromic and non-syndromic. Limited mouth opening in patients can affect the child growth and cause difficulties in feeding, swallowing and breathing
Case: A In this study, a female infant from Afghanistan, settled in Qom referred to AlZahra maternity with upper and lower fusion jaws is reported. According to clinical and laboratory examinations, infant had no other disorders except the above said disease, and her jaw fusion was non-syndromic
Conclusion: Treatment of this disease in early stages not only is easier, but also can be effective in terms of child's growth and feeding; because in most cases TMJ ankylosis occurs due to the lack of mobility and loss of function which leads to difficulties in oral operations
RESUMEN
Objective: Dental profession is associated with a high level of stress experienced by clinicians in private practice as well as students and instructors in dental school environment. The purpose of this study was to detect the main stressors in dental students of School of dentistry, Babol University of Medical Sciences in 2011-2012
Methods: In this descriptive, analytical study, data were collected via Dental Environment Stress [DES] questionnaire. Understudy subjects were all dental students in Babol University [n=199] selected by census sampling. Data were analyzed using chi-square and t-tests
Results: Six factors were found to be the main stressors in dental students: 1. More than one exam in the same day [2.76 [0.596]]; 2.Insufficient time interval between exams [2.74 [0.581]]; 3.Insufficient exam time [2.62 [0.693]]; 4.Instructors humiliating students or showing their dissatisfaction of the procedure done by the students in front of patients [2.61 [0.618]]; 5.Too many credits offered per semester [2.35 [0.849]] and 6. In appropriate behavior of the staff [2.33 [0.793]]. Of all departments in Babol Dental School, departments of Prosthodontics, Radiology and Endodontics caused the highest level of stress and anxiety in students and had statistically significant differences in this regard with other departments
Conclusion: The stressors had greater impacts on female students particularly the fourth year dental students. Attempts must be made to modify the curricula and exam schedules particularly in the most stressful departments to decrease the level of stress in dental students
RESUMEN
Antibiotics are commonly used for controlling the growth of porphyromons gingivalis [P.g] which is one of the most important etiologic factors in the periodontal diseases. Different side effects of synthetics and chemical drugs such as increasing the drug resistancy in the human pathogens have led to study on the herbal antibacterial effect. The aim of this study was to evaluate the antibacterial effect of cinnamon on the growth of porphyromons gingivalis in chronic periodontitis patients with deep pockets. In this experimental study, samples were provided from patients having pockets. After culturing the microorganism and diagnosis of P.g by gram staining and biochemical tests, cinnamon in different concentrations [10, 50, 100, 250, 500, 750 and 1500 mg/ml] with oil solvent were prepared and placed by disks in the cultures medium. Positive controls were amoxicillin, metronidazole, ciprofloxacin, amikacin and gentamycin. Oil was negative control. Then the plates were incubated for 24 hours in 37[0] C and then non-growth halos by disk diffusion method, MIC [Minimum Inhibitory Concentration] and MBC [Minimum Bactericidal Concentration] were determined. Data were analyzed using One-way ANOVA test. The results showed that the cinnamon at the concentration of MIC=750 mg/ml had the inhibitory effects of bacteria and at the concentration of MIC=1500 mg/ml had killing effect. However, this antibacterial effect compared with commonly used antibiotics [amoxicillin, metronidazole], was much weaker [P<0.001]. Cinnamon showed an antimicrobial effect on porphyromonas gingivalis in chronic periodontitis patients with deep pockets
