Objectives Many researchers have attempted to link the current concepts of anxiety and depression to periodontal disease. This study aimed to compare the level of anxiety and depression in Iranian patients with chronic periodontitis (CP) and periodontally healthy controls.

Methods Fifty CP patients and 50 periodontally healthy controls participated in this study according to our eligibility criteria. Periodontal clinical examination was performed using a Williams probe. The clinical attachment loss (CAL), pocket probing depth (PPD) and bleeding on probing (BOP) were recorded for all teeth except for third molars. In order to psychologically assess the individuals, the Beck’s Depression Inventory (BDI) and the Beck’s Anxiety Inventory (BAI) were used. The mean scores of BAI and BDI were compared between the two groups using the Student t-test.

Results The mean age of participants was 44.86±8.07 years. The mean score of BDI was 13.58±8.35 in periodontally healthy controls and 25.62±13.01 in CP patients. The mean score of BAI was 9.9±5.65 in the control and 21.02±13.63 in the test group. The Student t-test revealed a significant difference between the two groups in total score of BDI and BAI (P<0.000). A significant correlation was noted between the BDI and age (P=0.027) but BAI had no significant correlation with age (P=0.245).

Objectives This study aimed to scientometrically assess the oral medicine articles from Iran published in PubMed-indexed journals.

Methods In this descriptive cross-sectional study, the author information section of PubMed database was electronically searched for oral medicine articles published from the beginning of 2006 to the beginning of 2016 with at least one author from Iran using the keywords “oral medicine”, “oral and maxillofacial medicine”, “stomatology”, “stomatologist”, and “Iran”. The results were reported as frequency, and trend analysis was performed.

Results A total of 280 oral medicine articles published from the beginning of 2006 to the beginning of 2016 were found to have at least one author from Iran, which comprised 2.9% of the entire articles in this field. The majority of published articles were original articles (77%) followed by case reports (15%), review articles (5%), short communications (2%) and letter to editors (1%). The majority of articles had been published in J Dent Res Dent Clin Dent Prospects (18%), followed by J Dent (Tehran) (6.7%), and J Contemp Dent Pract (5.5%). The trend of publication of articles was ascending during this time period except for the year 2011. The frequency of articles had a significantly ascending trend during the aforementioned time period (P=0.004).

Objectives The aim of this study was to compare the antibacterial efficacy of two antiseptic agents namely Nanosil and Listerine for controlling water contamination.

Methods A In this experimental study, six dental units were divided into three groups of A, B, and C. First, sampling of the water from the turbines’ water ducts and the dental air-water sprays was performed early in the morning during two consecutive weeks on Saturdays (the first working day) and Wednesdays (the last working day). The samples were sent to a laboratory in sterile containers for bacterial colony counting. Next, group A and B units underwent decontamination once a week by Nanosil (1% hydrogen peroxide + silver ion) and Listerine, respectively. Group C was the control group. Afterwards, sampling was conducted again as in stage 1 to determine the bacterial colony count.

Results The Wilcoxon test indicated a statistically significant difference in the mean bacterial count between the samples taken before and after decontamination in Nanosil and Listerine groups, and the mean bacterial count was lower in the Nanosil group than in the Listerine group (P<0.001). A statistically significant difference was also found in the mean bacterial count between samples taken on Saturdays and Wednesdays before decontamination, and the mean bacterial count was higher on Saturdays than on Wednesdays (P<0.001).

Conclusion Both Listerine and Nanosil were effective in decreasing the microbial colony count in the dental unit water lines (DUWLs). The mean bacterial count was lower in the Nanosil group than in the Listerine group.

Objectives Due to advances in knowledge and treatment of diseases, life expectancy has increased worldwide. This study aimed to determine the prevalence of systemic diseases and medication intake by dental patients referred to dental clinic of Hamadan Dental School.

Methods A total of 800 patients referred to the Department of Oral Medicine from October 2013 to May 2014 were studied. The data extracted from patient charts included demographic data, systemic diseases, and medication intake, which were analyzed using the Chi-square test and Fisher’s exact test with SPSS version 16.0.

Results Of all, 28.8% of participants were males and 71.2% were females. The mean age of participants was 32.3 years. The total prevalence of systemic diseases was 30.5%. The most common condition was endocrine diseases. The total prevalence of medication intake was 20% and the most common medications taken were supplements and antihypertensive medications.

Objectives The posterior superior alveolar artery (PSAA) is one of the branches of the maxillary artery that is located on the lateral wall of the maxillary sinus. The aim of the present study was to evaluate the detectability, position, and diameter of the posterior superior alveolar (PSA) canal and its relationship with the alveolar ridge using cone-beam computed tomography (CBCT).

Methods A total of 257 CBCT images were evaluated. The PSA canal location was categorized into three forms of intra-osseous, below the membrane, and on the outer cortex of the lateral sinus wall. The distance between the lower border of the artery and the alveolar crest, the distance between the artery and the medial wall of the sinus, and the diameter of the artery were all measured. The prevalence of sinusitis and mucous retention cyst was also determined. The Chi-square test and independent t-test were used for statistical analysis.

Results The most common type of PSA canal was intra-osseous, followed by beneath the mucosal membrane and on the outer cortex of the lateral sinus wall. The lowest distance between the PSA canal and medial sinus wall and ridge crest, and canal diameter were higher in males (P<0.05). In addition, sinus pathologies were significantly more common in males than females (P<0.05).

Objectives Dentin dysplasia (DD) is a rare disorder, which is not accentuated in dental practice. DD has 2 types. Type I is manifested by tooth mobility, short roots, reduced pulp space and normal crowns. Type II or coronal DD is characterized by normal crowns in permanent teeth but discolored crowns in primary teeth. Denticles are detectable in the pulp chamber of teeth in type II DD. Many uncertain aspects of this condition include its etiology, diagnosis, and treatment planning. For a long time, extraction of mobile teeth was the main possible choice, which would lead to psychosocial problems that needed psychological interventions. The present study aimed to collect and classify the recent information on DD.

Methods An electronic search of the literature was carried out in PubMed and Google Scholar from 1977 to 2018. Duplicates were eliminated and the retrieved articles and relevant textbooks were thoroughly reviewed.

Results Although DD has an unknown etiology, it is known for a fact that it has a hereditary trait. The present article provides some information about DD, including possible etiological factors, clinical, radiographic and histological manifestations, diagnosis and current treatment options.

Objectives Dental fluorosis is a condition characterized by hypomineralization of tooth structure. It manifests as bilateral white opaque discolorations. Patients with these kinds of staining and discoloration often present to dental offices in young ages, seeking esthetic solutions. Color, shape and structural alterations in the anterior teeth could lead to significant esthetic complications for young patients. There are many cosmetic options to correct the unpleasant appearance of the anterior teeth. Dental bleaching is a conservative treatment for stained or dark-colored teeth. Micro-abrasion and removal of the outer layer of the tooth is another effective and successful method to treat fluorosis. Resin infiltration can also significantly change the esthetic appearance of such teeth.

Case Micro-abrasion followed by tooth bleaching and application of resin infiltrate was used in this study as a minimally invasive and inexpensive approach to treat discolored teeth due to dental fluorosis.

Conclusion To treat discolored teeth affected by dental fluorosis, a minimally invasive and inexpensive approach would be micro-abrasion followed by tooth bleaching and resin infiltration. This approach obviates the need for more invasive techniques such as veneers and crowns while it meets the esthetic demands of patients.
