Equal access and distribution of services among all people is one of the main objectives of health services and patient satisfaction is an important factor in evaluating these objectives. This study aims to investigate the access and satisfaction of elementary school children to dental services in Rasht.

In this cross-sectional descriptive study, first, we divided different areas of the city into three regions, and  by a simple random sampling method  selected  one school among  the schools in each region.. Data were collected in the questionnaire. The statistical analysis was performed using  SPSS software version 24. Significant  p value was set at 0.05.

In this study, 78% of study subjects had access to dental care and 22.1% faced barriers. High cost of dental treatments and dental fears were the main barriers. 55/9% of parents were satisfied with the dental care provided.

It is concluded that the access of elementry school children to dental services in Rasht is easy and the most important obstacle is child fear of dentistry and high dental costs.

Malocclusion is a common oral disease that, in addition to damaging the functioning of the oral system and hygiene, can harm a person’s social relationships and mood by negatively affecting their beauty and self-esteem and reduce the quality of life. Many malocclusions, if detected, can be corrected at the right time by spending less time and money, which plays a significant role in the quality of life.

In this applied research, 76 students in the range of 12 to 14 years old (39 girls and 37 boys) were evaluated in four groups. The first group consisted of individuals with normal overjet and 3≤  mm anterior crowding. The second group consisted of less than 2 mm overjet and 3≤  mm anterior spacing. The third group has 6≤ mm overjet with crowding and1 ≥ mm spacing. The fourth group has a control group consisting of subjects with normal occlusion. To examine the effect of this malocclusions on quality of life, The Oral Health Related Quality of Life (OQLQ) questionnaire was used. For statically analyses Kolmogorov-Smirnov and Kruskal-Wallis test were used. The significance level in all tests was 0.05.

The results showed that there was no statistically significant difference between the four groups in each domain (oral functioning, social aspect, dentofacial beauty and dentofacial beauty awareness). (p> 0.05).

Malocclusions such as anterior crowding, anterior spacing and increased overjet do not affect the quality of life of untreated 12-14 year old subjects.

The aim of this study was to evaluation the 10 years Clinicaopathological pattern of oral squamous cell carcinoma in Babol, Iran (2008 – 2017).

This descriptive retrospective research is based on data of 45 patients’ records. The data, that are noted down in the specified check list,( consist of various kind of demographic, clinical ,pathology,  history of medical and dentistry, and etc). was registered. then data was analyzed by SPSS21 and χ2 and student’s T.test.P value in which the cases with less than 0.05 are considered to be meaningful.    

The average age range of women is 68.15±10.869, which is significantly higher than men’s average (48.15±9.869) (p=0.031). The most prevalent reason of patients’ visit is existence of lesion in the mouth which most common sign was pain. The majority of clinical feature of basic lesion was ulceration. Also, according to the check list, totally gingiva, alveolar ridge and retromolarpad, then tongue, buccal mucosa, lips, palate and floor of the mouth respectively, are the area’s most frequently involved.

Oral squamous cell carcinoma, indicates that the average age of women is significantly higher than the men. The main chief complaint of patients’ is the existence of lesion with the basic of ulceration, accompanied with the pain. In most areas of the oral cavity, there is a possibility of oscc.

The temporomandibular joint’s disease is a group of complex diseases, many of which have no clinical signs and are identified through diagnostic assays, including radiological images. One of the methods of imaging that provides information about this disease is CBCT imaging. The purpose of this study was to evaluate the condylar bony changes in CBCT images of patients referring to the Radiology Center of a Dental School in 2019.

In this descriptive cross-sectional study, CBCT radiographs of 206 patients (121 females and 85 males) referring to the Radiology Center of a Dental School were chosen in order to determine hypoplasia, hyperplasia, bifid condyle, sclerotic changes, flattening, erosion and osteophyte in both sides. These radiographs were studied by a trained dentistry student to determine the changes.

The prevalence of condylar bony changes was 65.3% and no difference was observed between right and left condyles. The highest frequencies of condylar bony changes was related to flattening with a frequency of 131 condyles (31.7%), erosion with a frequency of 78 condyles (18.9%) and osteophyte with a frequency of 76 condyles (18.4%).

In the population of this study, there is a correlation between age and the prevalence of condylar bony changes and the prevalence of flattening, erosion, and osteophyte. Erosion also significantly increased in women and osteophyte increased in men.

Lichen planus is an inflammatory chronic illness with unknown cause that can irritate the oral mucosa. P53 is associated with malignant changes in oral epithelial cells. MMPs can destroy intercellular junctions and cause acantholysis. It seems that MMP-3 plays a significant role in this regard. The purpose of this study was to evaluate the salivary levels of P53 and MMP-3 in the patients with Oral Lichen planus (OLP) compared with the control group.

30 salivary samples were collected from patients with OLP (15 with erosive Oral Lichen planus (EOLP) and 15 with reticular Oral Lichen planus (ROLP)) and 30 salivary samples from healthy people as a control group. The salivary P53 and MMP-3 level was assayed by ELISA method. Statistical analysis of the Student’s t-test, ANOVA and Pearson correlation coefficient was performed.

The salivary concentrations of P53 and MMP-3 in patients with EOLP were significantly higher than patients with ROLP and control group, but no significant difference was found between control group and patients with ROLP.

The salivary concentrations of P53 and MMP-3 were significantly different between different clinical types of OLP.

The aim of this study was the evaluation of the effect of scad training software on shade matching ability of dental students.

84 students who passed shade matching topic in their theoritical courses were devided into two groups of case and control.They passed the exam of scad software in two steps. Interval of tests was six weeks.The case group unlike the control group get the training of scad between these two steps.The data were entered into SPSS software (version 21) to determine the progress of the students ability for shade mathching after training.

 In this study the case group showed significant progress in results Their score varied in various tests from the minimum 0.9 to the maximum 9.2 . According to the results, training effect of the scad software method was better than conventional method in Color differentiation in Exact Match  𝜫  /100 (P,0.0001) and from statistical point of view it has been improved shade matching ability rather than conventional method as much as 6 score. Also Difference in Matching Pair Total Light & Dark /29   evaluation was statisticaly significant that means after training , scad group had less wrong Diagnosis than control group. (P,0.001)

Training with scad software had significant effect on increasing the accuracy of students shade matching abbility.

Dental anxiety is a frequently encountered problem in dental offices which result in avoidance of dental care for most patients. Providing acceptable evidence based therapies for such patients is essential. Generally, dental anxiety can be managed by psychological interventions, behavioural techniques and pharmacological treatments, or a combination of them, depending on the level of dental anxiety, patient characteristics, clinical situations, type and duration of dental treatment. Pharmacological approaches can help to manage the patients using either level of sedation from mild sedation to general anesthesia. Pharmacological agents are usually sedative in action and do not eliminate anxiety but merely enhance patient acceptance. The agents used are varied and diverse and include nitrous oxide, benzodiazepines and narcotics, and they can be administered via different routes. This paper aims to review some pharmacological points in administration of sedative drugs in the management of dental anxiety.
