Abstract The purpose of this study was to evaluate the relationship between volatile sulphur compounds (VSC) and gingival health status, and to monitor the changes in VSC in early dental plaque-induced gingivitis. Using an experimental gingivitis model, twelve subjects between 19 and 28 years old, with a healthy gingival status, refrained from brushing and flossing one randomly selected half of the mandibular arch for two weeks. At baseline and during six subsequent appointments, gingival inflammation (GI), bleeding on probing (BOP), and sulfide levels (SUL) were measured using the Gingival Index and the Diamond Probe/Perio 2000 System. The Spearman correlation was used to compare the relationships between SUL, GI, and BOP on the brushing (B) and non-brushing (NB) sides. Data on the NB side revealed a stronger correlation than on the B side. Wilcoxon rank sum was used to evaluate the differences between mean SUL, GI, and BOP scores on the B and NB sides over time. Results indicate that SUL were the first periodontal parameter to show a significant difference between sides. SUL were significantly higher on the NB side at 4 of the 6 data collection intervals; therefore, SUL may be associated with the initiation and progression of early plaque-induced gingivitis.

Background Many studies have investigated the adherence to professional codes of ethics by nurses. However, no study has explicitly examined the relationship between workload and adherence to professional codes of ethics among Iranian nurses. Objective This study aimed to explore the relationships between workload and adherence to professional codes of ethics among a sample of Iranian nurses. Materials and Methods A cross-sectional descriptive study was conducted on 213 nurses who were randomly selected from the different wards of Shahid Beheshti Hospital of Kashan, Iran. Data collection instruments included a personal characteristics questionnaire, the Nursing Ethics Questionnaire, and the National Aeronautics and Space Administration Task Load Index. The Chi-square, the Spearman correlation coefficient, the Kruskal–Wallis, and Mann–Whitney U tests were used to analyze the data. Results A majority of nurses were females (77.5%), married (79.3%), and permanently employed (55.4%). The mean of the overall perceived workload and adherence to professional codes of ethics were 76.36 ± 13.64 and 13.98 ± 2.58, that were at high and moderated level, respectively. Spearman correlation test showed no significant correlation between perceived workload and adherence to professional codes of ethics ( r = 0.03, P = 0.6). A significant difference was found between the mean scores of adherence to professional codes of ethics in nurses working in different departments ( P < 0.001). Conclusion Participating nurses perceived high levels of workload but their mean adherence to professional codes of ethics was at a moderate level. The perceived workload was indirectly correlated with adherence to professional codes of ethics.

ABSTRACT Objective: The aim of this retrospective study was to evaluate the relationship between orthodontic treatment and gingival health. Materials and Methods: A total of 251 patients among whom 177 were girls and 74 were boys, recruited from the records pool of the Department of Orthodontics, Faculty of Dentistry, University of Gazi, were included in the study. Patients’ treatments have been completed by postgraduate students during the period between 2006 and 2012. Patients’ folders were analyzed according to their age, treatment time, and the type of orthodontic treatment. Intra-oral photographs were analyzed, and the presence or absence of visible plaque, visible inflammation, and gingival recession were recorded, and incisor inclinations analyzed on lateral cephalometric films, before and after orthodontic treatment. Results: No statistically significant difference was found in patients treated with functional appliances before and after treatment. In patients treated with fixed orthodontic appliances, visible plaque, visible inflammation, and gingival recession showed significant increases after treatment, gingival biotype did not show any significant difference. Positive correlation was found between lower incisor position and gingival recession in patients treated with fixed appliance and extraction. And also cuspids were the teeth with the highest prevalence of gingival recession. Conclusion: Considering the relationship between orthodontic treatment and gingival health, cooperation among patients, orthodontists, and periodontists is important.

The Relationship

This study aims to investigate the effect of technical competence in certain balance elements, an important parameter in rhythmic gymnastics, on sportive success in taekwondo poomsae athletes and the relationship between them. The study was conducted on 12 female taekwondo athletes (age: 17.6±1.2; height: 159.26±3.1 cm; weight: 50.79±1.82 kg; BMI: 20.88±0.98 kg/m2). The participants were selected from successful athletes who were in the top 6 in their own category in the national taekwondo competition held this year. The athletes performed 6 balance elements in rhythmic gymnastics, i.e. side passé (SP), 90° forward (90°F), side split with hand support (SSWHS), Arabesque with trunk forward (A), Cossack (C) and free leg to the side (FLS), and the Y balance test. The relationship between these balances that were assessed by 3 international judges and success rating was identified using the Spearman correlation test. The level of significance was accepted as p<0.05. As result, a statistically significant difference was found between side passé and split with hand support, balances used in rhythmic gymnastics, and success ratings (p<0.05). While no statistically significant difference was found between other balances, i.e. 90° forward, arabesque with trunk forward, cossack and free leg to the side and sportive success, there was a high relationship between them. In addition, there was no statistically significant difference between sportive success and right and left anterior (RAB, LAB) posteromedial (RPMB, LPMB) and posterolateral (RPLB, LPLB) reach distances. In conclusion, since the study found a high relationship between sportive success and technical competence of poomsae athletes in the two technical side balances, it is suggested that basic gymnastics training can be effective in improving the balancing skills of taekwondo poomsae athletes.

Objectives: The aim of this study was to investigate and compare the level of halitosis in patients with/without fixed crowns and in addition the influence of various crown parameters on halitosis was also explored. Methods: In total, 96 subjects (fixed crowns = 52; no crowns = 44) participated in the study. The levels volatile sulphur compounds (VSCs) of hydrogen sulphide (H2S), methyl mercaptan (CH3SH), and dimethyl sulphide (CH3SCH3) were evaluated with breath samples using gas chromatography and used for classification as presence or absence of halitosis. The periodontal clinical parameters for all the participants as well as the crown parameters for participants with fixed crowns were also evaluated. Cross tabulation, Chi-square test, and one-way analysis of variance tests were used for the statistical analysis and comparisons. Results: Breath samples revealed, 50 (52.1%) participants were suffering from halitosis. Out of VSCs, the level of CH3SCH3 (62.5%) was found to be the most prevalent. Significant correlations were observed between the presence of fixed crowns and oral halitosis (p < 0.001). Statistically significant difference in the concentration of H2S and CH3SH (p < 0.001) and no significance for CH3SCH3 (p = 0.075) between patients with/without fixed crowns was found. The presence of halitosis was more prevalent in the subjects with crown parameters (subgingival margin, over-contoured margin, open-crown margin, over-contoured and under-contoured crowns) considered clinically defective/unacceptable (p < 0.05). Conclusions: Presence of fixed dental crowns significantly contributes to the oral halitosis. Dental crowns with defects significantly impair the hygienic conditions and oral microflora resulting in high prevalence of halitosis.

AbstractThis study analyzes the relationship between contrast-sensitivity and higher-order aberrations (HOA) in mild and subclinical-keratoconus in subjects with good visual-acuity (VA). Keratoconus group (including subclinical-keratoconus) and controls underwent autokeratometry, corneal-tomography, autorefraction and HOA measurement. Contrast-sensitivity was tested using a psychophysical two-alternative forced-choice Gabor patches in three blocks (6, 9, 12 cycles/deg). Controls were compared to the keratoconus group and to a keratoconus subgroup with VA of 0.00 LogMar group ("keratoconus-0.00VA"). Spearman correlation tested association between HOA and contrast-sensitivity. Twenty-two keratoconus subjects (38 eyes: 28 keratoconus, 10 subclinical-keratoconus, 20 keratoconus-0.00VA) and 35 controls were included. There was a significant difference between control and keratoconus, and between control and keratoconus-0.00VA, for keratometry, cylinder, thinnest and central corneal thickness (p < 0.001). Controls showed lower HOA and higher contrast-sensitivity for all spatial-frequencies (p < 0.001). Most HOA were negatively correlated with contrast-sensitivity for all spatial-frequencies for keratoconus group and for 9 and 12 cycles/deg for keratoconus-0.00VA. Keratoconus subjects with good VA showed reduction in contrast-sensitivity and increased HOAs compared to controls. HOA and contrast-sensitivity are inversely correlated in subjects with mild keratoconus despite good VA. This suggests that the main mechanism underlying the decreased vision quality in keratoconus is the increase of HOA.

Objective: The purpose of this study was to analyse the prevalence of tonsilloliths and to determine radiographically whether there is a relationship between tonsilloliths and dental plaque-related pathologies in a series of digital panoramic radiographs. Materials and Methods: This retrospective study included digital panoramic radiographs of 859 patients admitted for a routine dental examination. The panoramic images were examined for both the presence of tonsilloliths and the number of decayed, missing, restored tooth and apical periodontitis. Periodontal bone loss was also measured in thirds of optimal bone height according to the root length and finally a percentage of bone loss was obtained for each panoramic radiograph evaluated. Results: Tonsilloliths were observed in 141 (16.4%) of all individuals. While there was no significant difference regarding the number of decayed teeth and restored teeth between tonsillolith cases (TT) and cases without tonsillolith (TC), the number of missing teeth and apical periodontitis in TT was significantly higher than TC (p: 0.004, p: 0.030, respectively). There was a significant difference between the groups in terms of the mean percentage of bone loss (p: 0.001; p< 0.05). In addition, cases showing bone loss between one-third and two-thirds of the optimal bone height in the TT group (52.5%) were significantly higher than those in TC (45.5%) (p: 0.035; p< 0.05). Conclusion: The relationship between dental plaque-related pathologies and tonsilloliths, observed in this retrospective study, should be confirmed by Computed Tomography studies and randomized, prospective, clinical trials conducted in a multidisciplinary manner.

Abstract The acute phase refers to physiological and metabolic alterations that ensue immediately after onset of infection or tissue injury. A variety of changes in the organism act in concern to neutralize the inflammatory agent and faster healing of damaged tissues. In contrast with the specificity of cellular and humoral immunity, the acute phase changes are nonspecific and occur in response to many conditions. Periodontal disease is a chronic inflammatory process that occurs in response to a predominantly Gram-negative bacterial infection originating from dental plaque. Increased levels of acute-phase proteins have been noted with gingival inflammation, including during experimental gingivitis and periodontitis, reflecting the locally stressed environment. Here, an attempt is made to discuss the importance of acute phase reactants. How to cite this article Vandana KV, Vandana KL. Acute phase reactants - A review. CODS J Dent 2014;6;96-101
