The Palatal injection is one of the most painful procedures in dentistry which could establish an unpleasant experience for pediatric patients. No study has been carried out to assess the effects of pre-cooling with ice during palatal injection for children yet. The present research is focused on comparison of the efficacy of pre-cooling and topical anesthetic gel on the pain perception of pediatric patients during the palatal injection.

This study is a randomized clinical trial with Split Mouth design. Fourteen 7-10 year-old Children who required bilateral Palatal anesthesia administration for routine dentistry procedures in one session had been selected and randomly categorized under two groups: Case Group(cooling) and control Group(Gel). Palatal injection was applied in the case group after using ice for one minute, and in the control group after consuming Benzocaine 20% anesthetic topical gel for one minute by one operator. The pain perception was assessed using SEM & Wong-Baker Faces pain rating scale. Mann-U-Whitney test was used for statistical analysis. P <0.05 was considered statistically significant.

The means of SEM scales were 1.42 and 1.57 for the study and the control group, respectively which was insignificant (p<0.9). The means of Wong-Baker pain rating scales for both the study and the control group were 2.86 which was not significant (p<0.9).

There seem to be no difference between using ice precooling and topical anesthetic gel for children receiving palatal anesthesia injection.

Behavioral managment of young children and  mentally or physically handicapped children in dental clinic is one of the major challenges for dentists. Therefore hospital dental services(general anesthesia or sedation) is an effective solution for the treatment of these children, so we we decided to evaluate the oponions of parents of children who have had dental experience in hospital services. The results will lead to have better consultation with the parents of these children, to accept this type of treatment.

In this descriptive study, 64 parents of children with hospital dental experience were selected as the sample. The parents were selected from two centers, the first group were patients admitted from Kerman city and was treated in one of the hospitals of the city and the second group consisted of patients who were admitted from one of Tehranchr('39')s areas with high socioeconomic status and  they were treated at a hospital in Tehran. They were then interviewed and their statements recorded. Interviews were conducted from all stages of treatment, part to part, from the decision to treat the child until the end of the anesthesia phase. Subsequently, individualschr('39') statements were recorded and coded. And were evaluated based on content analysis.

The findings of this study indicated that the main cause of treatment in this study was dental caries (90% in the first group and 100% in the second group). Complications of anesthesia were the most common cause of  parentschr('39') concerns ( 80% in both groups) about anesthesia, with most (70%) reporting that these concerns were transmitted from  those people around them. Parents said consulting with a dentist and anesthesiologist has reduced their concerns and made them satisfied with dental treatment under general anesthesia. 18 percent of parents described child malaise as a post-treatment problem. 45 percent of parents found staff apprehension to be suitable and a useful tool in reducing their anxiety during practice.

The results showed that complications of anesthesia and non-awareness of the child, systemic disease of the child, probability of prolongation of operation during anesthesia, and possible injuries in the operating room were the most important causes of parental concern about anesthesia treatment, and increased awareness through consultation with the dentist and anesthesiologists are effective in reducing this concern. Therefore, since hospital dental services is one of the best therapeutic approaches for the treatment of young children and patients with mental and physical disabilities, it can be possible to reduce parental concern by raising awareness of the benefits and disadvantages of hospital dental treatment in society,to be aware of such treatment options.

Implementing informed strategies along with changing the attitude of general dentists can lead to many improvements in child behavioral management skills. . Therefore, the present study was conducted to evaluate the attitude of general dentists toward pediatric behavior guidance techniques

In this descriptive cross-sectional study, 160 dental practitioners in Yazd city in 2018 were randomly selected and the attitude of them regarding pediatric behavior guidance techniques Collected by a valid and reliable set up questionnaire about five non-pharmacological and two pharmacological pediatric behavioral management techniques. Data were analyzed by SPSS23 software, and T-test.

There was a significant difference between the mean scores of attitude of men and women in using " hand-over-mouth " method (P = 0.034) and also in "sedation" method (P = 0.035) and " General Anesthesia  "(P = 0.041) There was a significant difference between the mean attitude score of under 35 years old and over 35 years old groups. Using behavioral control techniques among  general dentists who visit less than 10 children per month with general dentists who visit more than 10 children per month in attitude toward using voice control methods (P = 0.008), Positive reinforcement (P = 0.002) Tell-Show-Do (P = 0.016) General anesthesia (P = 0.029) There was a statistically significant difference.

the most acceptable methods for behavior guidance in children were Tell-Show-Do, positive reinforcement, general anesthesia, and sedation. Respectively female general dentist were more inclined to use non-invasive methods, and younger general dentists tended to use non-pharmacological methods.

Education in the field of medical sciences is an important process which practical skills is an important part of it. The purpose of this study was to compare the effect of two methods of live demonstration and videotape methods, for teaching Fissure Sealant and PRR, SSC, pulpotomy and pulpectomy on learning and satisfaction of 9th-semester dental student of Tehran University of Medical Sciences.The study was conducted to answer the question of whether the videotape methods can be as effective as live demonstration considering the educational needs of students.

In this experimental study, 62 undergraduate students of 9th-semester dental student of Tehran University were divided into two groups and voluntarily enrolled in the study. To assess studentschr('39') level of knowledge, pre-test and post-test were taken from all students at the beginning and at the end of the course. In the first group the skills was taught by the professor on the dental model or extracted deciduous tooth. and in the second group for teaching the same topics, appropriate educational films that included the same training items, was shown. At the end of the course, each student was evaluated on the dental model doing the same skills and scored by a checklist. Studentschr('39') satisfaction was also measured by filling out a designed questionnaire.

No significant differences were found in the pre- and post-test scores of the two groups except for the two questions (P Value> 0.05). The mean scores of the students in the two groups were similar in different sections and in terms of total score, and there was no significant differences. The results of the satisfaction questionnaire also showed more than 85% satisfaction in videotape methods.

We found that videotape methods was as effective and useful as live demonstration in acquiring studentschr('39') skills and knowlage.

Rhabdomyosarcoma is a malignant neoplasm and the most common soft tissue sarcoma in children. The current frontline treatment for rhabdomyosarcoma is a multi-modal approach, comprising chemotherapy, surgical resection, and/or radiation therapy. Radiation therapy during odontogenesis can lead to delayed sequel such as hypodontia, microdontia, and dwarfed teeth with underdeveloped roots. This case reports an abnormal root development due to a history of rhabdomyosarcoma. The aim of this report is to describe delayed oral manifestations following treatment strategies in rhabdomyosarcoma and to highlight the role of pediatric dentist in rhabdomyosarcoma cases due to secondary oral and dental complications.
