The Effect of Finishing and Polishing Procedures on the Surface Roughness of Composite Resin Materials
Authors: Attar Nuray 
Published: July 2019

Abstract

Aims
The aims of this study were to evaluate the effect of various finishing and polishing procedures on the surface roughness of six different composite resin materials (Artemis Enamel, TPH Spectrum, Filtek A–110, Filtek Supreme Enamel, Solitaire 2, and Filtek P–60) as well as to evaluate the effectiveness of the surface sealant application (BisCover) on the surface roughness after finishing and polishing procedures of tested composites.

Methods and Materials
Specimens (n=168) measuring 5 mm in diameter x 2 mm in thickness were fabricated in a plexiglass well covered with a Mylar strip using six composite resins. A control group of seven specimens of each material received no polishing after being cured under the Mylar strip. Twenty-one specimens for each composite were randomly divided among three finishing and polishing groups (n=7). Each group was polished using a different system: Carbide bur/Sof-Lex disc, Carbide bur/Enhance disc with polishing paste, and Carbide bur/Edenta composite finishing kit. The average surface roughness (Ra, ìm) of the control and treated specimens were measured with the Mitutoyo Surftest–402 Surface Roughness tester. After a surface sealant (BisCover) was applied to all treated specimens, according to manufacturer's instructions, the average roughness (Ra) was measured again. Results were statistically analyzed using analysis of variance (ANOVA) and the post-hoc Scheffe's test at a p<0.05 significance level.

Results
Significant differences were found for the surface roughness (p<0.05) with interaction among composite resins and the finishing systems used (p<0.05). Enhance/Biscover finishing and polishing procedure surface was not significantly different from the Mylar strip surface groups (p>0.05). The Mylar strip group was not significantly different from the Sof-Lex/BisCover and Edenta/BisCover groups. The ranking of mean Ra values by materials was as follows: Filtek Supreme Enamel < Filtek A110 < TPH Spectrum < Artemis <Filtek P–60 < Solitaire 2. The ranking of mean Ra values by polishing systems was as follows: Enhance/BisCover < Mylar Strip < Sof-Lex/BisCover < Edenta/BisCover < Sof-Lex < Enhance < Edenta.

Conclusion
Smoother surfaces were recorded for the Enhance/BisCover and the Mylar strip-formed surface groups. The composite finishing kit Edenta significantly increased the Ra for all tested composites (p<0.05). But after finishing with Edenta, the use of a surface sealant (BisCover) significantly improved the surface smoothness of all tested composites (p<0.05). Use of BisCover surface sealant on anterior and posterior resin composite restorations after finishing and polishing procedures is recommended.

Authors: Adeyemo Wasiu Lanre , Ladeinde Akinola Ladipo , Oguniewe Mobolanle Olugbemiga 
Published: July 2019

Abstract

Aim
Extraction healing complications have been attributed to several factors. The influence of trans-operative complications on an extraction site wound healing was the focus of this investigation.

Methods and Materials
This prospective study was conducted at the Oral Surgery Clinic of the Department of Oral and Maxillofacial Surgery of the Lagos University Teaching Hospital (LUTH) in Nigeria . Subjects selected were those referred for one or two adjacent extractions and who satisfied the inclusion criteria for the study. The relevant pre-operative information recorded for each patient were age and sex of patient, indications for extraction, time taken to extract the tooth, tooth/teeth removed, and any trans-operative complications. Extractions were performed with dental forceps, elevators, or both under local anaesthesia. Patients were blindly evaluated on the third and seventh post-operative day for socket healing assessment without reference to preoperative information on the patients.

Results
Seventy-three (24.25%) of 301 teeth considered for socket healing assessment had various transoperative complications due to accidental crown, root, or alveolar bone fractures. Of the 73 extractions with trans-operative complications during extraction, 18 developed a socket healing complication, while 17 of the 228 extractions without trans-operative complications developed socket healing complications (p = .000). The mean (SD) time taken to extract teeth developing healing complications was also found to be significantly longer than those without healing complications (p < .01).

Conclusions
The study demonstrated the combination of tooth/bone fragments in the socket and increased time of extraction due to trans-operative complications and accidents predispose to the development of extraction site wound healing disturbance.

Authors: Doshi Dolar , Baldava Pavan , Anup Nagaraj , Sequeira Peter S. 
Published: July 2019

Abstract

Aim
This study was conducted to test the null hypothesis that no difference exists in the oral hygiene knowledge and practices of university students in different courses when they have equal opportunity to access health-promotive dental care.

Methods and Materials
The study was conducted using 120 students each from the medical and engineering colleges at the University of Manipal Academy of Higher Education who had easy access to the dental college within the campus which provides health-promotive dental care to all its patients. A self-administered structured questionnaire consisting of questions on demographic data, oral hygiene knowledge and practices, and dental service utilization patterns was distributed among the students. The data collected was analyzed using SPSS 10 version.

Results
Statistically significant differences were found between the two groups with respect to the knowledge of fluoridated toothpastes, frequency of toothbrush renewal, use of dental floss, and a tongue cleaner (p<0.001). The groups were similar in all other practices including the utilization of dental services. There were no significant differences between the self-reported oral hygiene knowledge and practices among medical and engineering university students, but the knowledge levels of the students were considerably lower than expected.

Authors: Ogliari Fabrício Aulo , Campregher Ulisses Bastos , Samuel Susana Maria Werner , Fortes Carmen Beatriz Borges , Medina Alberth David Correa , Collares Fabricio Mezzomo 
Published: July 2019

Abstract

Aim
The purpose of this study was to evaluate the effectiveness of three commercially available light emitting diode (LED) light curing units (LCU) (Elipar FreeLight - 3M ESPE; UltraLume LED2 - Ultradent; and Single V - BioArt) for polymerizing Z250-A3 composite (3M ESPE) using Knoop hardness, polymerization depth, and flexural strength properties.

Methods and Materials
The XL 2500 (3M ESPE) LCU, which is a conventional halogen unit, was used as a control. In all cases the curing time was 20 seconds. Hardness was determined 24 hours after composite cure for 10 samples of 8 mm diameter and 2 mm height for each LCU tested. Samples were stored dry in a lightproof container prior to testing. The depth of cure of the composite was measured immediately after composite polymerization for each LCU using three samples 4 mm in diameter and 6 mm in height. Flexural strength was determined for five samples 24 hours after immersion in distilled water at 37°C. Each sample measured 25 mm in length, 2 mm in width, and 2 mm in height for each LCU tested.

Conclusion
The results were treated statistically for comparison of the LCUs. In all cases the results obtained by LED LCUs were not different or were higher than a conventional halogen LCU.

Clinical Significance
Second generation LED LCUs were as effective as/or more effective than a halogen LCU for polymerization of the used composite. The present study shows second generation LEDs have the potential to replace halogen LCUs.

Effect of Two Light-emitting Diode (LED) and One Halogen Curing Light on the Microleakage of Class V Flowable Composite Restorations
Authors: Korkmaz Yonca , Attar Nuray 
Published: July 2019

Abstract

Aim
The disadvantages of light cured composite resin materials with respect to microleakage are predominantly a result of polymerization shrinkage upon curing. It has been shown curing methods play a significant role in polymerization shrinkage of light-cured composite resins. The purpose of this study was to investigate the effect of light-emitting diode (LED) light curing units (LCUs) compared with a halogen LCU on microleakage of three different flowable composites using self-etch adhesives.

Methods and Materials
A total of 63 extracted human premolars were prepared with standardized Class V cavity preparations on the buccal and lingual surfaces of each tooth. The occusal margin of the cavities was located on the enamel and the gingival margin was on dentin. Teeth were randomly assigned to three groups of 21 teeth each as follows: Group 1: Adper Prompt L-Pop + Filtek Flow (3M ESPE); Group 2: AdheSE + Tetric Flow (Ivoclar, Vivadent); and Group 3: Clearfil Protect Bond + Clearfil Protect Liner F (Kuraray Medical Inc.). All the groups were subdivided into three groups according to the curing lights used (n=7). Two LED LCUs, Elipar FreeLight and Elipar FreeLight 2 (3M ESPE), and one halogen-based LCU, Hilux Expert (Benlioglu), were used. All teeth were then immersed in 0.5% basic fuchsin dye solution for 24 hours after thermocycling (500 cycles; between 5°C to 55°C). The teeth then were longitudinally sectioned and observed under a stereomicroscope (40X magnification) by two examiners. The degree of dye penetration was recorded separately for enamel and dentin. Data were analyzed with the Kruskal-Wallis and Mann-Whitney tests with the Bonferroni correction.

Results
No statistically significant differences in microleakage were observed between groups either on enamel or dentin (p>0.05).

Conclusion
With the limitation of this in vitro study, the differences in microleakage between LCUs used were not statistically significantly different. Elipar Free Light 2 reduces curing time which can be considered as an advantage.

HIV: Infection Control Issues For Oral Healthcare Personnel
Authors: Terezhalmy Geza T. , Huber Michaell A. 
Published: July 2019

Abstract

Aim
To present the essential elements of an infection control/exposure control plan in the oral healthcare setting with emphasis on HIV infection.

Methods and Materials
A comprehensive review of the literature was conducted with special emphasis on HIV-related infection control issues in the oral healthcare setting.

Results
Currently available knowledge related to HIV-related infection control issues is supported by data derived from well-conducted trials or extensive, controlled observations, or, in the absence of such data, by best-informed, most authoritative opinion available.

Conclusion
Essential elements of an effective HIV-related infection control plan include: (1) education and training related to the etiology and epidemiology of HIV infection and exposure prevention; (2) plans for the management of oral healthcare personnel potentially exposed to HIV and for the follow-up of oral healthcare personnel exposed to HIV; and (3) a policy for work restriction of HIV-positive oral healthcare personnel.

Clinical Significance
While exposure prevention remains the primary strategy for reducing occupational exposure to HIV, knowledge about potential risks and concise written procedures that promote a seamless response following occupational exposure can greatly reduce the emotional impact of an accidental needlestick injury.

Published: July 2019

Abstract

Background
The transmigration of a mandibular canine is a rare phenomenon, the etiology of which is not clear. The literature on this rare condition is reviewed, and six cases of transmigrated mandibular canines are presented.

Report
Panoramic radiographic examination of six patients revealed each patient had one impacted transmigrated mandibular canine. Of the six impacted teeth, the left mandibular canine was involved in four instances and the right in two. In one case the transmigrated canine was associated with a dentigerous cyst.

Summary
Transmigration of the mandibular canine is a rare event, and early radiographic examination of the patient is important for treatment. In addition, future studies may lead to a better understanding of this rare anomaly and improvement of the classification criteria.

Authors: Mantzikos Katherine , Segelnick Stuart L. , Schoor Robert 
Published: July 2019

AbstractBackgroundThere are no published case reports that hematomas occur on the floor of the mouth as a result of periodontal surgery.ReportThese three case reports document post surgical hematoma formation on the floor of the mouth that pose problems with the diagnosis, prognosis, and patient management. All cases involved periodontal surgery where extensive reduction of tori and bony exostoses were required. Two cases resulted in hematomas in the floor of the mouth. However, a change in the post surgical management for a third case demonstrated possible prevention of hematoma formation.SummaryHematomas in the floor of the mouth can be a resolving post surgical phenomenon or a serious vascular insult to this region of the oral cavity. This report clarifies the diagnosis, prognosis, and the best management protocol through the presentation of three cases.CitationMantzikos K, Segelnick SL, Schoor R.

Authors: Almas Khalid , Rayman Salim 
Published: July 2019

Abstract

Aim
The aim of this paper is to highlight the need to integrate cultural care into dental hygiene practice.

Background
Culture can be better understood through the concepts, beliefs, and norms of the culturally diverse population of the United States. It is important to understand cultural perceptions of oral health in order to manage transcultural barriers that may arise during the utilization of oral healthcare services. It is assumed cultural competence can only be achieved through the knowledge of various cultural backgrounds in an extremely diverse US population.

Conclusions
There is a need to integrate cultural awareness, knowledge, identification, and respect into the dental hygiene curriculum through the incorporation of competencies and standards associated with dental hygiene practice. Future dental hygienists should be culturally competent to render oral care to an ever expanding and diversified US population.

Osteochondroma of the Mandibular Condyle: Literature Review and Report of a Case
Authors: Martins Wilson Denis , de Oliveira Ribas Marina , de Sousa Maria Helena , Zanferrari Fernando Luiz , Lanzoni Thais 
Published: July 2019

Abstract

Aim
The intent of this report is to present a brief review of the literature on osteochondroma and to present a case involving the surgical removal and replacement of a major portion of the condyle and angle of the mandible using free autogenous mandibular bone.

Background
While osteochondroma is the most common tumor of skeletal bones, it is relatively uncommon in the jaws occuring at the condyle or the tip of the coronoid process. This benign cartilage-capped growth is usually discovered incidentally on radiographic examination or on palpation of a protruding mass in the affected area. Malocclusion and progressive facial asymmetry are common findings in most cases of condylar osteochondroma.

Report
A case of a 29-year-old woman with an osteochondroma of the mandibular condyle is presented. Surgical treatment was tumor resection, grafting, and reshaping of the mandibular angle and ramus. As this lesion is usually asymptomatic and discovered incidentally on radiographic examination, the general practitioner usually is the first professional to make the diagnosis.

Summary
Condylectomy cannot be recommended as routine in all cases.37 Common surgical treatments include condylectomy and reconstruction.24 If the tumor involves only a limited area of the condylar surface, then preservation of the remaining portion of the condyle and reshaping should be done. Reasons for not taking such a conservative approach are the possibilities of malignancy and the risk of recurrence. In this case report the extraoral vertical ramus osteotomy, associated with free autogenous mandibular bone, presented several advantages.

Primary Tuberculosis of the Tongue: A Case Report
Authors: Garg Rajeev Kr. , Singhai Pawan 
Published: July 2019

Abstract

Aim
The purpose of this article is to report a rare case of primary tuberculosis of the tongue.

Background
Tuberculosis is an infectious, chronic granulomatous disease that can involve almost any organ in the body, but primary lesions are usually confined to the lungs. Oral lesions are an infrequent occurrence in tuberculosis, and tuberculosis of the oral cavity is often a consequence of active pulmonary tuberculosis. Although primary tuberculosis in the oral cavity has been documented, it is a rare occurrence.

Report
A 42-year-old male patient presented with chief complaints of severe pain and ulceration on the ventrolateral surface of the left side of the tongue, measuring about 1.25×1.50 cm with surrounding erythema and induration of one-month duration. The ulcer was initially painless but became painful later with increased severity over time. The sore tongue caused difficulty in eating, drinking, swallowing, and even talking. The patient also complained of malaise for some duration, but there was no history of fever, cough, weight loss, and his bladder-bowel habits were normal. An excisional biopsy differentiated the lesion from squamous cell carcinoma and confirmed the diagnosis.

Summary
Even though primary tuberculosis in the oral cavity is a rare finding, it must be included in the differential diagnosis of mucosal lesions. This case provides a clinical example of the importance of this inclusion for the well being of the patient and for the community due to the communicable nature of the disease.

Chlorhexidine's Effect on Sealing Ability of Composite Restorations Following Er:YAG Laser Cavity Preparation
Authors: Geraldo-Martins Vinicius R. , Robles Fabio R.P. , Matos Adriana B. 
Published: July 2019

Abstract

Aim
The aim of this study was to evaluate the influence of chlorhexidine on microleakage of composite restorations in class V cavities prepared with a carbide bur (CB) and a erbium:yttrium-aluminum-garnet (Er:YAG) laser.

Methods and Materials
Cavity preparations were created on the buccal surfaces of 48 bovine incisors using different methods then equally dividing them into four groups. Groups I and II were prepared with a #56 CB in a high speed handpiece while Groups III and IV were prepared with a Er:YAG laser at 350m J/4Hz on enamel and at 80.24 J/cm2 on dentin. The cavity preparations were rinsed with 2% chlorhexidine solution before the application of Clearfill SE Bond system and placement of a Z100 composite resin restoration. After 24 hours, the teeth were polished, thermocycled, and sealed with cosmetic varnish. The samples were then immersed in 2% methylene blue for four hours and sectioned in the buccolingual direction to determine the degree of microleakage.

Results
After statistical analysis (Kruskal-Wallis, p<0.05), no significant differences were verified among the tested groups and between the evaluated cervical or incisal margins of the restoration.

Conclusion
The use of the chlorhexidine did not interfere with the adhesion process regardless of whether a CB or the Er:YAG laser were used to prepare class V cavities when restored with the tested self-etching adhesive system.
