Children with Attention Deficit Hyperactivity Disorder (ADHD) exhibit a kind of negligence in performing their daily tasks and activities, which also affects the maintenance of oral health. Due to the low quality of life in these children, it is doubtful that the Oral Health-Related Quality of Life (OHRQoL) will be affected compared to healthy children. 

In this study, 106 untreated ADHD children referred to the clinic of Taleghani Hospital in Gorgan City, Iran, in 2018-2019 were selected through the convenient sampling method. Data were gathered using the Child-Oral Impacts on Daily Performance (Child-OIDP) and Clinical Examination Questionnaires. Data were analyzed through SPSS-18, descriptive statistics indexes, the Mann-Whitney test, the Shapiro-Wilk test, and the Spearman correlation test. 

The most common self-expression problem of ADHD children was decay (88.6%), followed by pain, erupting, and tooth sensitivity, respectively. The OHRQoL score of these children was 12.79, which OIDP obtained. The index and the decay score of these children were 6.62, obtained by the Decay, Missing, and Filled Teeth (DMFT) index—the correlation between total DMFT and OIDP. The index score was positive and significant (r= 0.256, P= 0.008). A significant inverse correlation existed between the total DMFT score and parents' education level (r= -0.271, P= 0.005) and (r= -0.283, P= 0.003), respectively. 

There is a significant relationship between oral health and tooth decay index. Better oral health and decay, missing, and filled teeth index are associated with a higher quality of life.

The aim of the current research was to investigate the existence of any possible relationship between existential anxiety and core self-Evaluation (CSE), in predicting life orientation of patients with cancer.
The study employed a correlational research design. One hundred patients with cancer (skin, breast, and stomach), 20 to 40 years of age, referring to hospitals in Ardabil were selected by purposeful sampling. The selected individuals completed existential anxiety, core self-evaluation and life orientation questionnaires. To analyze the data, stepwise regression analysis was used.
The findings of the study showed that, there was a meaningful and positive relationship between existential anxiety and predicting pessimistic attitude towards life (P In regards with patients with chronic disease, in addition to physical health and medical treatments, special attention should be paid to their mental health because chronic diseases such as cancer could endanger their lives. The results also demonstrated that with medical advances in the treatment of these patients, their mental health should also be considered with the help of mental health professionals

Laser irradiation has been suggested as an adjunct to traditional methods of canal preparation but few studies are available on the antibacterial effect of diode laser in pulpectomy of primary teeth. The purpose of the present study is to investigate the antibacterial effect of diode laser in pulpectomy of primary teeth, in addition to define the optimal and harmless diode lasing conditions in the root canal.
A total of 125 single rooted primary teeth were selected. After traditional canal cleaning, they were divided in 2 groups. Sixty-five specimens after culturing of Enterococcus faecalis into the canals, were divided in 3 groups: (1) traditional canal cleaning with 0.5% NaOCl irrigation, (2) method of group 1 1.5 W diode laser (980 nm, pulse), (3) without treatment (5 specimens). Then the specimens were cultured and after colony counting under light microscope, were statistically analyzed by Kruskal-Wallis and Mann-Whitney tests. For 60 specimens, temperature rise of apical and cervical parts of the external root surface were measured using 2 thermocouple type K, when radiating a 1.5 W diode laser into the canal.
In the first experiment, the diode laser group showed tmost reduction in bacterial count. And in the second experiment, the mean temperature rise of external root surface was less than the threshold of periodontal ligament (PDL) damage.
Diode laser with a power output of 1.5 W, is effective in reduction of E. faecalis bacterial count without damaging periodontal structures.

Detection of caries lesions on approximal surfaces of posterior teeth is difficult, since wide contact points hamper direct visual inspection. Due to the importance of the early detection of dental caries, the aim of this study is to compare the performance of different methods (visual, bitewing radiography and DIAGNOdent) in detecting approximal caries in primary molars.
Thirty six children were selected from patients referred to the pediatric dentistry department of Shahid Sadoughi University of Medical Sciences, Yazd, Iran. Two examiners evaluated 229 approximal surfaces of primary molars using: visual inspection, radiography and a pen-type laser fluorescence device (DIAGNOdent) for the presence of proximal caries. The surfaces were evaluated by 2 other examiners for the presence of white spots or cavitations. Sensitivity, specificity and accuracy (percentage of correct diagnosis) were calculated for each method. The area under the receiver-operating characteristics curve (A z) was calculated for DIAGNOdent device. The inter-examiner reproducibility was calculated using the intra-class correlation coefficient (ICC values) for laser Fluorescence and agreement coefficient for visual and radiographic methods.
At white-spot threshold, a DIAGNOdent device presented better performance. At cavitation threshold the radiographic method demonstrated higher sensitivity than visual inspection and DIAGNOdent device .In this threshold, all methods presented high specificities
A DIAGNOdent device performs better in white spot threshold. However, radiography shows better performance in detecting more advanced approximal caries lesions.

Oral-facial-digital syndrome as heterogeneous developmental conditions is characterized by abnormalities in the oral cavity, facial features and digits. Furthermore, central nervous system (CNS) abnormalities can also be part of this developmental disorder. At least 13 forms of OFDS based on their pattern of signs and symptoms have been identified so far. Type 1 which is now considered to be a ciliopathy accounts for the majority of cases. It is transmitted in an X-linked dominant pattern and caused by mutations in OFD1 gene, which can result in embryonic male lethality. In this study, we present a family suffering from orofaciodigital syndrome type I who referred to Medical Genetics Research Center, Shahid Sadoughi University of Medical Sciences in 2015. Two female siblings and their mother shared a novel 2-base pair deletion (c.1964-1965delGA) in exon 16 of OFD1 gene. Clinically, the sibling had oral, facial and brain abnormalities, whereas their mother is very mildly affected. She also had history of recurrent miscarriage of male fetus.

Curcumin is the active ingredient in the traditional herbal remedy and dietary spice turmeric (Curcuma longa). Curcumin has a surprisingly wide range of beneficial properties, including anti-inflammatory, antioxidant, chemopreventive and chemotherapeutic activity. on basis of recent studies; it has antifungal and antibacterial effects. The aim of this study was in-vitro evaluation of antifungal effect of curcumin on candida albicans and comparing it with nystatin.
after preparing curcumin powder, 3 laboratory methods were used to evaluate antifungal effect. The first method was cell count technique, used to evaluate the amount of candida albicans after time, in different concentrations of curcumin in Dimethyl sulfoxide (DMSO). The second was cup bioassay, in which inhibitory a zone of curcumin in DMSO was evaluated in sabouraud culture plates; and in third method, inhibitory zones of dried disks; which contained curcumin in DMSO were evaluated.
the result of all three methods showed that curcumin has antifungal effect and this effect increases in more concentrations.
curcumin has apparent and dose dependent antifungal effect on candida albicans.

Pulpectomy is a conservative treatment plan for primary necrotic teeth and Zinc Oxide Eugenol is still a good choice as root canal filling material but long term studies on poor prognosis molars are limited and almost contradictory. The purpose of this study is to evaluate the clinical and radiographical success rate of pulpectomy of necrotic primary molars using ZOE as the root canal filling material. 152 records of 76 primary molars on which two-visit pulpectomy had been performed were selected. The records with a complete and enough clinical history and high quality radiographs of before the treatment and follow up sessions were included to the study. The least follow up was 6 months and the most one was 59 months (with the mean follow up of 24 months). The treatments were noted successful if clinically had no signs and symptoms and radiographically, the size of pathologic radiolucencies of before the treatment have been reduced or at least remained without any changes. Then obtained information was analyses in SPSS 17 and by Chi- square and Log Rank tests. From all 76 cases 5 teeth (6.6%) were radiographically failed that all of them were second primary molars and 2 teeth were clinically failed (2.6%) that both were second primary molars. Two-visit pulpectomy of primary molars with ZOE as root canal filling materials is one of the most successful treatments for necrotic teeth.
