Background: Fixed orthodontic appliance patients have a high risk to increasing plaque accumulation in tooth surface due to the presence of fixed appliance components. Using mouthwash with antibacterial agent from herbal material can control dental plaque accumulation. Bay leaf (BL) contains active compounds such as essential oil, tannin and flavonoid that have been known as an antibacterial agent. Purpose: The purpose of this study was to determine the effect of rinsing with 60% of BL aqueous decoction to the accumulation of dental plaque in fixed orthodontic appliance patients. Method: This research was an experimental clinical research with pretest and post-test control group design conducted on 20 subjects with age ranged between 18-25 years old. All subjects were undergoing the last stage (finishing) of fixed active orthodontic treatment. The subjects were instructed to rinse with 60% of BL aqueous decoction and 0.2% chlorhexidine as a control. Wash out period that needed between rinsing with 60% of BL aqueous decoction and rinsing with 0.2% chlorhexidine was 7 days. Each mouthwash used routinely for 7 days with same duration and intensity. Plaque scoring was measured before and after each treatment using Orthodontic Plaque Index (OPI). Result: One-way Anova test showed that there was a significant difference in the plaque index before and after treatment between the group of rinsing with 60% of BL aqueous decoction and group of rinsing with chlorhexidine (p<0.05). Conclusion: Rinsing with 60% BL aqueous decoction can decrease the accumulation of dental plaque in fixed orthodontic appliance patients.

Orthodontic treatment may lead to environmental changes in the oral cavity that may occur in a number of users of the orthodontic appliance, such as changes in bacterial concentration, salivary buffering capacity, salivary acidity (pH) and salivary flow rate. Xylitol stimulates salivary flow and helps restore saliva acid/base balance because it cannot be converted to acid by oral bacteria. To identify the difference in salivary pH before and after chewing xylitol gum in the users of fixed orthodontic appliance. This research is quasi-experimental with one group pretest-posttest design. Samples were students of SMA Kolombo Sleman who used a fixed orthodontic appliance. Data were analyzed using a Wilcoxon test. The salivary pH of the users of a fixed orthodontic appliance before chewing xylitol gum mostly belonged to acid criterion (43.8%), and the base criterion (34.3%). After chewing xylitol gum, the salivary pH of the users of fixed orthodontic appliance mostly belonged to a neutral criterion (78.1%). The results of the Wilcoxon test showed that the salivary pH before and after chewing gum xylitol in the users of fixed orthodontic appliance had a P value of 0.027 <α 0.05. There is a significant difference in salivary pH before and after chewing xylitol gum in users of fixed orthodontic appliance.

Objective: The aim of this study was to evaluate the association of the skeletal pattern and angle class with the occlusal plane (OP). This study also examined the effect of orthodontic treatment on this plane. Methods: Lateral cephalometric radiographs of a sample of 135 patients were collected. The angles between the Frankfort horizontal, palatal plane (PP), mandibular plane (MP), and the OP were analyzed and compared between several groups and subsequently before and after treatment. Results: The statistical comparison between 3 skeletal frame groups demonstrates that the cant of the OP showed a major difference. This difference was greater in class III subjects. Examination revealed that the OP was not meaningfully affected within the Angle classification. Statistically, a significant correlation was found between OP steepness and the vertical skeletal pattern. A significant rise of OP/sella-nasion (SN) for class I (p=0.019) and II (p=0.015) after orthodontic treatment. In addition, patients treated with elastics showed a significant decrease of OP/MP (mandibular plane) in Angle class III and considerable increase of OP/SN and OP/PP in Angle class II. Observations of the group treated with bimaxillary extractions showed that OP/SN (sella nasion line) and OP/PP differ in a meaningful way. Conclusion: This study confirms the association between the skeletal pattern and the OP inclination in adults. Concerning the Angle classification, there was no significant difference between the groups. Orthodontic therapy had an influence on the inclination of this plane for the different malocclusions. Premolars extraction in class I cases significantly modified the OP. For class II and III malocclusions, the OP inclination was mainly altered by the use of intermaxillary traction elastics.

The aim of the study was to evaluate changes in dental status during fixed orthodontic treatment. A total of 60 patients with diagnosed malocclusion were included. Subjects were divided in 3 groups (20 subjects in each group). The first group was treated with dental cream GC Tooth Mousse, and the second group with Fluorogal - solution with a low concentration of fluoride (0.05% F). Control group comprised 20 patients. All subjects received precise instructions for oral hygiene and exclusion of dietary intake before fixed orthodontic appliance was placed and during each control. In our study clinical oral health status (DMFT-index) was registered before and at the end of the orthodontic treatment. The subjects treated with dental cream GC Tooth Mousse at the end of the orthodontic treatment had increased DMFT-index 5.85 in comparison to the beginning of the treatment, where the average value of the index was 5.25 (however, the difference was not statistically significant). A statistically significant difference between medium values of the DMFT-index before and after the orthodontic treatment was detected in the control group. The results of this study show that DMFT-index increased in a group of dental patients undergoing orthodontic therapy with fixed appliances. The patients must follow good instructions, motivation, and control of oral hygiene during the treatment. Key words: carious lesions, fixed orthodontic appliance

SUMMARY The aim of this in vitro study was to quantitatively evaluate the internal gap of resin composites of high-and low-viscosity used in single- and incremental-fill techniques in Class I cavities exposed to thermal cycling (TC) using optical coherence tomography (OCT). Cavities of 4-mm depth and 3-mm diameter were prepared in 36 third molars randomly distributed into four groups, according to viscosity of restorative resin-based composite (high or low viscosity, all from 3M Oral Care) and technique application (bulk or incremental fill) used (n=9): RC, high-viscosity, incremental-fill, resin-based composite (Filtek Z350 XT Universal Restorative); BF, high-viscosity, bulk-fill, resin-based composite (Filtek One Bulk Fill); LRC, low-viscosity, incremental-fill, resin-based composite (Filtek Z350 XT Flowable Universal Restorative); and LBF, low-viscosity, bulk-fill, resin-based composite (Filtek Flowable Restorative). Single Bond Universal Adhesive system (3M Oral Care) was used in all the experimental groups. The incremental-fill technique was used for RC and LRC groups (2-mm increments), and a single-layer technique was used for BF and LBF groups, as recommended by the manufacturer. The internal adaptation of the resin at all dentin walls was evaluated before and after TC (5000 cycles between 5°C and 55°C) using OCT images. Five images of each restored tooth were obtained. Images were analyzed using ImageJ software that measured the entire length of the gaps at the dentin–restoration interface. The length of gaps (μm) was analyzed using two-way repeated measures ANOVA and the Tukey tests (α=0.05). There was a significant interaction between material types and TC (p=0.006), and a significant difference among all material types (p<0.0001), before and after TC (p<0.0001). Increased internal gaps at the dentin–restoration interface were noticed after TC for all groups. RC presented the lowest value of internal gap before and after TC, while LBF showed the highest values of internal gap after TC. In conclusion, TC negatively affected the integrity of internal gap, whereas high-viscosity, incremental-fill, resin-based composite presented better performance in terms of internal adaptation than low-viscosity, bulk-fill materials in Class I cavities.

The Relationship

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.
