Abstract

Aim
The aims of this study were to evaluate the prevention of enamel demineralization and the shear bond strength (SBS) of orthodontic brackets bonded with fluoride and no fluoride conventional and selfetching adhesives and to analyze the characteristics of enamel near the bond area using a polarized light microscope (PLM) following demineralization and remineralization cycling (Des Re).

Methods and Materials
Fifty bovine incisors were selected and divided into five groups according to the adhesive system used during the bonding process: G1, Transbond™ XT Adhesive; G2, Single Bond 2 Adhesive; G3, Optibond Solo Plus; G4, Clearfil SE Bond; and G5, Clearfil Protect Bond. Transbond™ XT was used to fix the brackets to the teeth in all groups. After bonding, the groups were separated into cycling and control subgroups. The specimens were submitted to SBS testing and evaluated under a PLM. The results were submitted to ANOVA and Tukey's post hoc tests (p<.05).

Results
There were no significant differences for SBS after Des-Re cycling. The Clearfil Protect Bond showed the SBS to be statistically lower than the other adhesives used for the control groups. After a cariogenic challenge, the Single Bond adhesive showed an SBS significantly lower than Transbond XT. The Des-Re cycling increased the enamel demineralization induced after the cariogenic challenge.

Conclusions
The cariogenic challenge did not reduce the SBS. Optibond Solo Plus and Transbond™ XT adhesives presented the highest SBS while Clearfil Protect Bond had the lowest. The PLM showed that the cariogenic challenge increased the enamel demineralization for all adhesives evaluated, independent of the presence of fluoride.

Clinical Significance
An alternative material with the ability to prevent enamel demineralization should be used in orthodontic patients due to the higher accumulation of plaque around orthodontic brackets.

Porcelain Fused to Metal Crown as an Abutment of a Metal-Ceramic Resin-Bonded Fixed Partial Denture: A Clinical Report
Authors: Maleknejad Fatemeh , Ghavamnasiri Marjaneh , Modabber Maryam 
Published: July 2019

Abstract

Aim
This clinical report describes a conventional resin-based fixed partial denture for a 42-yearold woman to close an edentulous space in the region of the second maxillary premolar. While the first maxillary molar had been crowned with porcelain fused to metal (PFM) system 10 years ago and the first premolar was intact and sound except for a small carious lesion in the distal aspect. The essential clinical and laboratory procedures are illustrated.

Background
Multiple clinical studies document excellent long-term success of resin-bonded fixed partial dentures. In the 1970s, the Rochette resin-bonded fixed partial denture (RBFPD) was introduced. Next, to enhance retention and resistance form of posterior RBFPD preparation of parallel guide surfaces on the interproximal aspects of the adjacent teeth along with rests on the occlusal aspects to counteract dislodging forces was recommended.

Report
A 42-year-old woman presented with an extracted left maxillary second premolar. The first maxillary molar had been crowned 10 years ago and the first premolar had a small carious lesion in the mid distal of proximal aspect. To eliminate unnecessary cutting of the PFM of the first molar and crown preparation of the first maxillary premolar, the use of RBFPD was suggested and accepted by the patient.

Summary
This clinical report described the indication, the selection of a PFM-crowned abutment, and clinical procedures involved in the fabrication of RBFPD that provided a conservative solution for replacement of one posterior tooth.

Clinical Significance
RBFPDs can be used successfully in both the anterior and the posterior regions of the mouth to replace one or two missing teeth. However, the survival rate of RBFPDs is still considerably less than that of conventional fixed partial dentures. The principal reason for failure is debonding of the framework from the abutment tooth. The selection of nonmobile abutment teeth, the preparation design that enhances retention and resistance form, and the tooth bonding technique are critical for success.

Gingival Abscess Due to an Unusual Nail-Biting Habit: A Case Report
Authors: Sousa Denise , Pinto Daniela , Araujo Rebecca , Rego Rodrigo Otavio , Moreira-Neto Jose 
Published: July 2019

Abstract

Aim
Nail-biting is one of the most frequent deleterious oral habits in children. It can result in systemic diseases or oral traumatic lesion. This report describes a case of gingival abscess in a child due to a fingernail-biting habit.

Case Description
A 5-year, 6-month-old female presented gingival swelling and fistula in the primary maxillary left central and right lateral incisors as an unusual sequelae to the periodontal tissues from fingernail-biting. A periodontal curette was used to remove the fragments and to curette the area. After the curettage, an exudate of blood and pus was drained. Then the area was irrigated with 0.12% chlorhexidine solution; applying finger pressure controlled the secretion. After one week, the patient returned with gingival swelling present in the same teeth. The same curettage procedure was performed. It was suggested that the deleterious habit was related to emotional tension and anxiety behaviors and the patient was referred for psychological treatment. When the patient returned one month later, she was still biting her fingernails, but she had stopped placing fragments into the gingival crevice. No more gingival inflammation or swelling was observed.

Summary
This paper presents an unusual case report of a gingival abscess due to a fingernailbiting habit in a child, probably related to an emotional condition.

Clinical Significance
The fingernail-biting habit can induce a periodontal traumatic injury yielding a more serious complication such as a gingival abscess.

Published: July 2019

Abstract

Aim
This study assessed the influence of current oral contraceptive pills on periodontal health in young females.

Methods and Materials
Seventy women ranging in age from 17 to 35 years (mean 24 years) had a comprehensive periodontal examination. Their current and previous oral contraceptive pill use was assessed by a questionnaire. A periodontal assessment was performed that included recording the following: plaque index, gingival index, probing depth, and attachment level at six sites per tooth. The periodontal health of women taking birth control pills for at least two years was compared to that of women not taking an oral contraceptive. The control and test groups were matched for socioeconomic status, age, oral habits, occupation, and educational levels.

Results
Although there was no difference in plaque index levels between the two groups, current oral contraceptive pill users had higher levels of gingival inflammation and bleeding on probing. However, no significant differences were found regarding mean probing depths and attachment loss between the two groups.

Conclusion
Women who were on oral contraceptive pills had more extensive gingivitis and gingival bleeding than their matched controls not taking them.

Clinical Significance
As birth control policies are advocated by most countries, and because oral contraceptives are the most widely used method for birth control, a need exists to assess the effects of oral contraceptives on the periodontal health of young women. Although additional studies are needed to better understand the mechanism of OC-induced gingivitis, female patients should be informed of the oral and periodontal side effects of OCs and the need for meticulous home care and compliance with periodontal maintenance.
Unusual Gingival Enlargement with Aggressive Periodontitis: A Case Report
Authors: Vishnoi Shivlal L. , Phadnaik Mangesh B. 
Published: July 2019

Abstract

Aim
This article describes the surgical management of a young, female patient with severe gingival enlargement of unknown etiology.

Background
Gingival enlargement frequently occurs as gingival hyperplasia, representing a reaction to a known stimulus or agent and, histopathologically, implies an increase in both extracellular matrix and cell numbers. The enlargement may range from mild, in which gingival architecture is minimally affected, to severe, in which the gingiva becomes bulbous and covers the clinical crowns of teeth. A number of local and systemic factors, such as plaque, hormonal changes, drug ingestion, and heredity, can cause or influence gingival enlargement. Mild to moderate increase in gingival bulk is relatively common, but massive gingival enlargement with associated bone resorption is rare.

Case Description
This case involved a 19-yearold female patient who presented with generalized severe gingival enlargement with aggressive periodontitis, a condition of some five to six months in duration.

Results
Based on a thorough clinical and radiographic examination, laboratory tests, and oral hygiene instructions, an internal bevel gingivectomy was performed to remove excess gingival tissue and areas of bone loss were debrided properly. There was no recurrence eight months following the last surgery.

Summary
Although we were not able to identify the exact cause of the gingival enlargement, amelioration of the unusual very soft, friable, enlarged gingivae and the severe periodontal attachment loss was observed.

Clinical Significance
Before initiating any periodontal management of a case of severe gingival enlargement with aggressive periodontitis, it is recommended to perform a complete extraoral and intraoral examination with radiographs, take a family and medical history, and determine if any medications may be responsible for the gingival enlargement. Additional testing and analysis, as described in this case, may be necessary.

Evaluation of Subantimicrobial Dose Doxycycline as an Adjunct to Scaling and Root Planing in Chronic Periodontitis Patients with Diabetes: A Randomized, Placebo-Controlled Clinical Trial
Authors: Gupta Satish , Bhongade Manohar L. , Deo Vikas , Jaiswal Ritika 
Published: July 2019

AbstractAimDiabetic patients have more severe periodontal destruction, but periodontal therapy can improve metabolic control. Recently, interest has focused on the use of subantimicrobial dose doxycycline (SDD) as a treatment paradigm. Therefore, this study was undertaken to evaluate clinical efficacy of SDD with scaling and root planning (SRP) in chronic periodontitis patients with diabetes.Methods and MaterialsTwenty chronic periodontitis patients with diabetes mellitus were randomly allocated to either a test and a control group. Clinical measurements were recorded at baseline and at six months for probing pocket depth (PPD), clinical attachment level (CAL), and gingival recession (GR). After SRP, patients in the test group were instructed to take SDD 20-mg capsules twice a day while patients in the control group took a placebo twice a day. Both groups were on this regimen for a six-month period.ResultsA greater reduction in mean PPD was demonstrated in patients in the test group compared to the control group. The mean CAL increase observed in the test group was significantly greater (0.67 mm) than that in the control group.ConclusionIt can be concluded that SRP, in conjunction with the SDD therapy described, is more effective then SRP alone in terms of CAL gain and PPD reduction in diabetic patients with severe periodontal disease.Clinical SignificanceGiven the widespread prevalence of both chronic periodontitis and diabetes, the proposed treatment approach will prove to be of great value and contribute significantly to the overall health of the patients.CitationDeo V, Gupta S, Bhongade ML, Jaiswal R.

Management of Aphthous Ulceration with Topical Quercetin: A Randomized Clinical Trial
Authors: Hamdy Ahmed Abd El-Meguid Mostafa , Ibrahem Mohamed Abd El-Moneam 
Published: July 2019

Abstract

Aim
Recurrent aphthous ulceration is the most commonly known oral mucosal disease. Quercetin is a useful therapeutic agent for the treatment of colitis and gastric ulcer. The objective of this study was to determine the effect of topical application of quercetin in the treatment of minor aphthous ulcers.

Methods and Materials
Forty male patients with no known pathology of the oral mucosa other than minor aphthous ulcers were enrolled in this study. Patients were randomly divided into two groups, each consisting of 20 patients. Group 1 (control group) patients used a benzydamine hydrochloride mouthwash three times daily. Group 2 patients placed two to three dabs of quercetin three times daily directly on their ulcers. Clinical evaluation of patients included assessment of ulcer size, pain measure, and interviews regarding the topical application of quercetin in terms of consistency, taste, local tolerability, and ease of application.

Results
The topical application of quercetin cream to minor mouth ulcers relieved pain and produced complete healing in seven of the Group 2 patients (35 percent) in 2–4 days, 18 patients (90 percent) in 4–7 days, and 20 patients (100 percent) in 7–10 days. When comparing the mean ulcer size after 10 days, lesions in the Group 2 patients were smaller than those in Group 1, and the size difference between the two groups was significantly different (p<0.004). Also, 90 percent of patients responded that they appreciated the ease of application when using the topical quercetin, and they did not object to its consistency or taste.

Conclusion
Quercetin is a safe, well-tolerated, and highly effective promising new, adjunctive treatment for healing common aphthous ulcers.

Clinical Significance
Although aphthous ulcers typically resolve on their own in one to two weeks, the daily topical application of quercetin may be useful in accelerating the healing process of minor aphthous ulcers.

Temporomandibular Disorders: A Report of 124 Patients
Authors: Martins-Junior Reynaldo Leite , Palma Antonio Jose Garcia , Marquardt Emilio Jose , de Barros Gondin Thais Monteiro , de Carvalho Kerber Florence 
Published: July 2019

Abstract

Aim
This study aims to present both the features of 124 consecutive patients with temporomandibular disorders (TMDs) and the results of a reversible, conservative, and low-tech treatment.

Methods and Materials
One hundred fifty-eight records of consecutive patients treated in School of Dentistry at the Univag-University Center in Varzea Grande-MT, Brazil, 124 of whom were considered TMD patients, were examined. The following data were obtained: gender, age, main complaint, diagnosis, co-morbidities, type of treatment performed, and treatment results. The patients who received a successful treatment were contacted for reevaluation four to six years after the conclusion of treatment.

Results
Pain was the main complaint for 92.7 percent of the patients. The majority of patients were female (female:male ratio of 4.1 :1), with a peak age range between 20 and 30 years. Roughly 59.7 percent of the patients were diagnosed as having a muscular TMD, 12.9 percent as an articular TMD, and 27.4 percent as a mixed TMD. The success rate for treatment was 91.7 percent, and there was a tendency toward the long-term maintenance of good results.

Conclusion
The features of the 124 TMD patients treated were similar to those reported in the literature with regard to gender, age, and diagnostic prevalence. Most of the disorders were of a muscular origin, and there was a predominance of women between 20 and 30 years of age. The conservative, reversible, and low-tech treatment success rate for TMD can reach values above 90 percent. Therefore, there is no need for invasive, irreversible, expensive, or high-tech treatments for the majority of patients.

Clinical Significance
The majority of TMD patients can benefit from reversible, conservative, and low-tech treatments such as parafunction control and therapeutic exercises that can be performed by any clinician once an accurate diagnosis has been made.

The Effect of a 16% Carbamide Peroxide Gel on Mercury and Silver Ion Release from Admixed and Spherical Dental Amalgams
Authors: Kasraei Shahin , Rezaei-Soufi Loghman , Azarsina Mohaddese 
Published: July 2019

Abstract

Aim
The aim of this study was to investigate the effect of 16 percent carbamide peroxide gel on mercury and silver ions released from admixed and spherical dental amalgams.

Methods and Materials
A total of 96 amalgam discs were prepared from two different types and brands of dental amalgam (admixed and spherical). The samples were stored at room temperature in glass tubes containing distilled water for 24 hours. The specimens were then polished and again immersed in distilled water at room temperature and stored for one month. Samples of both types of dental amalgam were treated with carbamide peroxide 16 percent gel (Nite White, Discus Dental, Inc., Culver City, CA, USA) for 14 and 28 hours (experimental group) and compared to samples not exposed to the bleaching agent but stored continuously in distilled water. Mercury and silver levels of each solution were measured using the VAV–440 analyzer system.

Results
Mercury and silver ions released from the experimental group were significantly greater than from the control group (p<0.001). There was no significant difference between the mean levels of mercury and silver ions in the two kinds of amalgams after treatment with 16 percent carbamide peroxide (p=0.119 for mercury and p=0.199 for silver). Increasing the storage time in the carbamide peroxide gel from 14 to 28 hours did not result in significant changes in the amount of ions released (p=0.329 for mercury and p=0.082 for silver). Also, the interaction effect between amalgam particles’ shape (admixed and spherical) versus storage time (14 versus 28 hours) was not statistically significant (p=0.901 for mercury and p=0.951 for silver).

Conclusion
Treatment with 16 percent carbamide peroxide gel increased mercury and silver ions released from admixed and spherical amalgams, compared to samples in the control group, but the difference between the two amalgams was not statistically significant.

Clinical Significance
The amount of mercury and silver ions released from high-copper dental amalgams during bleaching with 16 percent carbamide peroxide is in the safe range of mercury intake for patients.

The Influence of Cervical Preflaring of Root Canal on Determination of Initial Apical File using Gates Glidden Drills, Protaper, Race and Diamond-Coated Galaxy Files
Authors: Ashwini TS , Bhandari Sonam 
Published: July 2019

ABSTRACT

Aim
To investigate the influence of cervical preflaring on apical file size determination using four different rotary instruments.

Materials and methods
Fifty root canals from extracted human maxillary premolars with complete root formation, straight roots were used for the study. Access opening was done and the working length established with 8 no K-file for each canal. Teeth were randomly divided into five groups of 10 canals. In Group 1- no preflaring was done and acted as control and in Groups 2, 3, 4 and 5 cervical and middle third preflaring of the root canals were done using Gates Glidden drills, Protaper instruments, Race instruments and Galaxy files respectively.
After preflaring, the apical file size determination was done and the initial apical file (IAF) was fixed at the working length. Teeth were sectioned transversally 1 mm from the apex, with the binding file in position. The samples were imaged under stereomicroscope with 30× magnification. Root canal and file maximum diameters were recorded for each sample. The readings were subjected to analysis of variance test and Scheffe's multiple comparison test.

Results
Preflaring with Race instruments lead to most accurate determination of the IAF. It was followed by Protaper, Galaxy files and Gates Glidden drills.

Conclusion
Traditional method of apical size determination may lead to a substantial underestimation of actual canal size. Cervical preflaring increases the accuracy of apical size determination.

Clinical significance
Thus, cervical preflaring is recommended before selection of IAF as it increases the accuracy of apical size determination.
