Effect of awareness and reassurance on anxiety of dental implant candidates

Objectives Dental anxiety can be potentially problematic. Anxiety must be controlled in highly anxious patients in order to ensure a smooth procedure and prevent potential complications. Awareness and reassurance are believed to be efficient for anxiety control in patients undergoing dental procedures especially dental implant treatment. This study sought to assess the effect of awareness and reassurance of patients undergoing dental implant treatment on their level of anxiety.Methods In this experimental study, 40 dental implant candidates with a mean age of 37.5 years were selected and randomly assigned into two groups (n = 20). Case group patients received awareness and reassurance through a standard interview while controls only received routine information. Level of anxiety of the patients was determined pre- and postoperatively using the Spielberger State-Trait Anxiety Inventory (STAI). The anxiety scores of the patients in the two groups were statistically analyzed by Mann-Whitney U test.Results The preoperative anxiety scores of cases and controls were not significantly different (54.73 vs. 57.55; P > 0.05). However, the anxiety score of the case group was significantly lower than that of the control group postoperatively (52.30 vs. 60.64; P = 0.004). Also, male patients had a significantly lower anxiety score than females (P < 0.05).Conclusion Awareness and reassurance through a standard interview can efficiently decrease the level of anxiety of dental implant candidates. Furthermore, female patients often experience higher level of anxiety than males

Comparison of the Effect of Three Types of Iron Drops on Surface Roughness of Deciduous Teeth in a Simulated Cariogenic Environment

Objective: Iron deficiency anemia is among the most common types of childhood anemia. According to the World Health Organization, approximately 5 billion people were suffering from iron deficiency anemia worldwide in 2001. Aside from causing anemia, iron deficiency can negatively affect the physical and mental development of children and adolescents. Several studies have discussed the consequences of inadequate iron intake among which we may name changes in deciduous teeth. Considering the importance of iron supplementation, the present in-vitro study aimed at assessing the surface roughness of deciduous teeth following exposure to three different iron drops.Methods: This in-vitro experimental study was conducted on 90 sound anterior deciduous teeth that were divided into 6 groups. After surface preparation, the teeth were placed in cariogenic environment. Different ferrous sulfate compounds were added to 4 media and the remaining two groups were  considered as positive and negative controls. Fourteen days later, the specimens were removed from the media, sectioned labiolingually, polished and enamel and dentin microhardness were evaluated. The  mean microhardness value for the 15 specimens in each group was recorded. ANOVA was applied for comparison of data and LSD test was used for multiple comparisons.Results: No statistically significant differences were found in enamel microhardness of the 6 understudy groups. The mean microhardness of dentin was significantly different in the three understudy depths. Dentin microhardness immediately below the DEJ, at 250 Mm distance from the DEJ and at 450 Mm distance from the DEJ was (kgf/m2) 68.72 (10.00), 67.75 (8.75) and 68.75 (11.86) in group 1, 69.22(12.46), 73.06 (9.36) and 69.29 (8.01) in group 2, 68.533 (12.27), 64.63 (10.64) and 69.64 (10.15) ingroup 3, 83.033 (11.22), 71.68 (16.01) and 70.88 (17.60) in group 4, 60.080 (9.83), 63.52 (14.46) and65.49 (11.20) in group 5 and 91.91 (43.76), 88.62 (20.47) and 85.04 (26.56) in group 6 (p=0.001 for all three), respectively. Pair-wise comparison of groups revealed that the mentioned difference is due to the statistically significant differences between group 6 and other groups and the remaining groups were not significantly different.Conclusion: This study showed that iron supplementation had no effect on demineralization of tooth structure

Replantation of an Avulsed Maxillary Incisor after 12 Hours: Three-Year Follow-Up

Tooth avulsion is defined as the complete displacement of the tooth out of its alveolar socket. The treatment of choice is immediate replantation or if that is not possible, placement of the tooth in an appropriate storage media. This report presents replantation of an avulsed maxillary central incisor after 12 hours of storage in milk. The tooth was replanted and splinted. One week later, it was treated endodontically and calcium hydroxide dressing was placed for 1 month; subsequently, the tooth was obturated with gutta-percha. During three years of follow-up, no evidence of ankylosis or inflammatory resorption was observed. After three years, the tooth was stable and remained functional and esthetically acceptable

Comparative Evaluation of the Fluoride Recharge Ability of Two Glass Ionomers Obtained from Fluoridated Dentifrice and CPP-ACFP Paste: An In-vitro Study

Introduction: Glass ionomer cement (GIC) is a restorative material used in pediatric dentistry, which attaches to dental hard tissues and has cariostatic properties due to the ability for fluoride release. The present study aimed to assess the fluoride release and uptake capacity of two GICs in the presence of various fluoride sources. Methods: This in-vitro study was conducted on 120 disks composed of two GICs (Fuji II LC, Equia Forte System), which were prepared with the exact dimensions of 5×2 millimeters. Fluoride release ability of the samples was determined every 24 hours for seven days and weekly (days 7-21) using a combination of ion selective electrodes. The samples in each group were divided into three subgroups and subjected to no fluoride treatment, fluoridated dentifrice (once a day for one minute), and MI Paste Plus (once a day for one minute). After recharging the samples for seven days, the level of fluoride release was measured on days 1-7, 14, and 21. Results: The results of one-way analysis of variance indicated that the fluoride release ability of Fuji II was higher compared to that of EQUIA Forte (

Maxillary canine‒second molar transposition: A rare case report

Transpositions mostly involve the upper jaw and more frequently occur between the maxillary canine and first premolar. Herein, we present a case of a maxillary canine‒second molar transposition in a thalassemic patient

Incidence of dental developmental anomalies in permanent dentition among Ardabil population, Iran, in 2015-2016

BACKGROUND AND AIM: Dental anomalies are typically detected in radiographic screening. The present study was conducted with the aim of investigating the dental anomalies found in panoramic radiographs taken from the study population in Ardabil, Iran, in 2015-2016. METHODS: The present study was conducted on 1800 panoramic radiographs obtained from 799 men and 1001 women in the Radiology Department, Dental Faculty of Ardabil University of Medical Sciences, Ardabil. The radiographs were precisely evaluated in terms of various dental anomalies, including root dilaceration, missing teeth, impaction, retained deciduous, supernumerary teeth, peg lateral teeth, talon cusp, taurodontism, and lingual pit. The data were analyzed using the chi-square and Fisher’s exact tests. RESULTS: The results of this study revealed that 331 patients had at least one dental anomaly. Dilaceration with 42.0% was the most common anomaly. The other anomalies detected in the radiographs included missing teeth, impaction, lingual pit, peg lateral teeth, retained deciduous teeth, supernumerary teeth, talon cusp, and taurodontism with a rate of 20.2%, 18.4%, 10.8%, 10.2%, 7.8%, 6.6%, 1.5%, and 0.3%, respectively. No cases of microdontia, macrodontia, germination, and fusion were observed. Dental anomalies were more incident among women than men (P = 0.010). Furthermore, the detected anomalies had a higher rate in maxilla compared to mandible (P = 0.010). CONCLUSION: As the findings of this study indicated, dilaceration was the most common dental anomaly, followed by missing teeth and impaction, respectively.

Bilateral supernumerary maxillary lateral incisors: A rare case report

BACKGROUND AND AIM: Supernumerary tooth (ST) is considered as a developmental tooth abnormality in number that most often occurs in the anterior region of the maxilla. They may erupt or remain impacted in the alveolar bone. The impacted teeth can cause eruptional disturbances for the adjacent developing teeth. CASE REPORT: A case of bilateral supplemental maxillary lateral incisors in a nonsyndromic 9-year-old boy, with no adverse effect on the adjacent teeth, is reported. Patient’s medical history was non-contributory. Family history was negative for any dental abnormality. CONCLUSION: Radiographic assessment of both dental arches can discover any potential problem likely to develop during the course of the child’s growth. Early diagnosis is important in order to minimize the risk of complications. Formation of supplemental lateral incisors occurs less frequently, and bilateral cases are rarely found. KEYWORDS: Lateral Incisors, Tooth, Supernumerary, Tooth Abnormalities, Maxill

Evaluation of the relationship between pH and titrable acidity of five different of iron supplements with the absorption of iron ions in the anterior primary teeth (an in vitro study)

Background: Iron supplement is recommended for alleviating iron deficiency. Black discoloration of teeth is one of the side effects of consumption of iron supplements. Besides these effects, iron drops may also act directly on the dental hard tissues, with erosive lesions as possible outcomes of their content. In this regard, we decided to compare iron absorption of five types of iron drops in enamel and determine its relationship with pH and titrable acidity (TA) of them. Materials and Methods: In this in-vitro study The pH of 5 kinds of iron was measured by a digital pH meter. Each drop was titrated and then the TA was calculated. For this experimental study, 40 healthy anterior primary teeth were prepared and divided into 5 groups then exposed to iron drops. The level of iron absorption was determined by atomic absorption. The Pearson correlation test was used to analysis correlations between pH, TA, and absorption of iron ions in the anterior primary teeth. One-way ANOVA was used for statistical analysis. Statistical significance was set at P < 0.05. Results: The mean of pH in Kharazmi drops was significantly less than both Irovit, and FerroKids drops (P < 0.05) but did not differ significantly with other drops. Kharazmi drops TA was higher than all drops (P < 0.05). There was no significant difference between the mean iron ion adsorption, as well as between iron ion absorption with pH and TA also not found a statistically significant relationship. Conclusion: All drops have acidic content that increases their potential for erosion. Reducing the potential of the effects of iron drops on dental hard tissues should be of concern to all health professionals

Attitudes of Shiraz Dental Students toward Their Discipline and Future Career

Introduction: Interest, motivation, and satisfaction toward job are the factors guarantee the success in occupation. Job satisfaction itself is influenced by social factors. The rising admission rates of dental schools have further increased the anxiety of their students in recent years. This investigation was conducted on dental students to assess their attitude toward future career and the discipline at the time of entrance and graduation. Methods: This descriptive cross-sectional study was carried out on 140 dental students of Shiraz University of Medical Sciences within academic years 2010-2011 using a questionnaire made by researcher. The items of the questionnaire were about students’ attitude toward their discipline and future career. Data was analyzed by Kolmograph-Smirnove, ANOVA, and t-test. Results: The mean of total scores for the questionnaire related to student’s attitude toward their discipline (33.97+ 4.46) was higher than its theoretical mean score (27). The mean of total scores for the questionnaire related to student’s attitude toward their future career (16.42 +2.61) was lower than its theoretical mean (18). Investigating the difference between attitude toward discipline and future career among students of different semesters and age groups revealed no significant difference. Accordingly, no significant statistical difference was also realized between male and female students regarding the attitude toward discipline. But a statistically significant difference was observed between genders considering the attitude toward future career (P=0.037). Conclusion: This study showed that dental students of Shiraz University of Medical Sciences are interested in their discipline whereas their attitude toward future career was not desirable. This represents their anxiety toward future career. The results of this study could be taken into consideration for future planning and therefore open up a brighter horizon for the future career of these students

In-Vitro Comparison of Microleakage of Two Types of Restorative Glass Ionomer in Class V Cavities in Primary Teeth

Background and Aim: Glass ionomer cements (GICs) are the most common restorative material in pediatric dentistry. GlCs have the ability to chemically bond to enamel and dentine and can release fluoride. In clinical situations, microleakage is a major challenge when using glass ionomer cement. Therefore, this study was designed to compare the microleakage of two types of glass ionomer in primary teeth restorations. Materials and Methods: This experimental study included 80 maxillary anterior deciduous teeth. Class V cavities measuring 1.5 × 2 × 3 mm were prepared on the teeth. The specimens were randomly divided into two groups as follows: 1) Fuji II LC, 2) Equia Forte. The teeth were subjected to 500 thermocycles between 5 °C and 55°C by immersion in hot and cold water for 25 seconds. The samples were immersed in the fuchsia solution for 24 hours to test dye penetration. Then, the center of the restorations was cut buccolingually and the amount of microleakage was evaluated and scored under a stereomicroscope. Data were analyzed by chi-square test. Results: Based on the results of this study Fuji II LC GIC showed higher microleakage scores than Equia Forte GIC and a statistically significant difference was observed between the groups. (P <0.05) Conclusion: Equia Forte GIC may be a useful restorative material in the primary teeth restoration for young children due to the low microleakage score and the relatively quick placement
