Authors: Lin Shaul , Tillinger Gabriel , Zuckerman Offer 
Published: July 2019

AbstractAimThe purpose of this preliminary clinical report is to suggest a novel treatment modality for periodontal bifurcation lesions of endodontic origin.Methods and MaterialsThe study consisted of 11 consecutive patients who presented with periodontal bifurcation lesions of endodontic origin (endo-perio lesions). All patients were followed-up for at least 12 months. Treatment included calcium hydroxide with iodine-potassium iodide placed in the root canals for 90 days followed by canal sealing with gutta-percha and cement during a second stage. Dentin bonding was used to seal the furcation floor to prevent the ingress of bacteria and their by-products to the furcation root area through the accessory canals.ResultsA radiographic examination showed complete healing of the periradicular lesion in all patients. Probing periodontal pocket depths decreased to 2 to 4 mm (mean 3.5 mm), and resolution of the furcation involvement was observed in post-operative clinical evaluations.ConclusionsThe suggested treatment of endo-perio lesions may result in complete healing. Further studies are warranted.Clinical SignificanceThis treatment method improves both the disinfection of the bifurcation area and the healing process in endodontically treated teeth considered to be hopeless.CitationLin S, Tillinger G, Zuckerman O.

Abstract

Aim
Based on the hypothesis the application of a low-viscosity hydrophobic resin coating improves the bond of all-in-one adhesive, the purpose of the study was to evaluate the bond strength of four adhesive systems to bovine root dentin using the push-out test method.

Methods and Materials
The root canals of 32 bovine roots (16 mm) were prepared to a length of 12 mm using a FRC Postec Plus preparation drill. The specimens were allocated into four groups according to the adhesive system used: (Group 1) All-in-one Xeno III; (Group 2) All-in-one Xeno III+ScotchBond Multi-Purpose Plus Adhesive; (Group 3) Simplified Etch & Rinse One Step Plus; and (Group 4) Multi-Bottle Etch & Rinse All- Bond 2. A fiber-reinforced composite retention post was reproduced using an additional silicon impression and fabricated with DuoLink resin cement. The root specimens were treated with the selected adhesive systems, and the resin posts were luted in the canals with DuoLink resin cement. Each root specimen was cross sectioned into four samples (±1.8 mm in thickness), and the post sections were pushed-out to determine the bond strength to dentin.

Results
Group 2 (2.9±1.2) was statistically higher than Group 1 (1.1±0.5) and Group 3 (1.1±0.5). Groups 1 and 3 showed no statistically significant difference while Group 4 (2.0±0.7) presented similar values (p>0.05) to Groups 1, 2, and 3 [(one-way analysis of variance (ANOVA)] and Tukey test, α=0.05).

Conclusion
The hypothesis was accepted since the application of the additional layer of a low-viscosity bonding resin improved the bond of the all-in-one adhesive. Further studies must be conducted to evaluate the long-term bond.

Published: July 2019

AbstractAimThe aim of this study was to evaluatein vitroeffects of the combination of in-office and intracoronal bleaching on enamel and dentin bond strength and on dentin morphology.Methods and MaterialsBleaching treatment was performed on 128 bovine teeth for three weeks. Intracoronal bleaching was performed in groups G1 to G3, and in the other groups a combination of in-office and intracoronal bleaching was performed. The following agents and materials were used (n=16): G1- sodium perborate and water (SP); G2- 37% carbamide peroxide (CP); G3- 35% hydrogen peroxide (HP); G4- HP + cotton pellet soaked in water (CPW); G5- HP + SP; G6- HP + CP; G7- HP + HP; and G8- CPW (control). Seven days after bleaching treatment the teeth were sectioned into two halves. One half of each tooth was ground to obtain a flat dentin surface. Dentin and enamel fragments were treated with a dentin/enamel resin adhesive. Resin composite was inserted in two increments and polymerized for 20 seconds. Following the restorative procedures, specimens were sectioned into beams with a rectangular cross-sectional area of approximately 1 mm2. Microtensile testing was performed in a universal testing machine. Bond strengths (in MPa) were calculated and the data were submitted to an analysis of variance (ANOVA) and the Tukey test (α=0.05). For the scanning electron microscopy (SEM) observation, the exposed pulp chambers (n=5) were fixed, dehydrated, dried in a Critical Point dryer, and gold-sputter coated for analysis at standardized magnifications (500X, 1000X, and 2000X).ResultsNone of the bleaching techniques reduced the enamel bond strength, the best results observed were with the intracoronal treatments with SP and HP. In dentin all bleaching techniques reduced the bond strength with the exception of the in-office HP application technique. The SEM results demonstrated similar dentin surfaces for the G1, G3, G6, and G7 groups with more open dentin tubules found than in the other groups.ConclusionNone of the bleaching techniques tested reduced the bond strength of enamel, but they all reduced the bond strength of dentin with the exception of the group only treated with in-office bleaching using 35% HP. The worst bond strength results to dentin were observed in groups that received intracoronal bleaching with SP.CitationAmaral C, Jorge A, Veloso K, Rodrigues J, Erhardt M, Arias V.

Abstract

Aim
The aim of this in vitro study was to evaluate the cleaning capacity of different auxiliary chemical substances energized with ultrasound in radicular dentin using morphologic analysis.

Methods and Materials
Twenty-eight single-canal, mandibular incisors were prepared with the Hero 642 canal preparation system following the sequence: 25/12, 30/06, 35/02, and 40/02, 1 mm from the apex. The specimens were then divided into four groups of seven teeth. During biomechanical preparation the teeth were irrigated with 2 ml of distilled water between files. Each group of specimens (n=7) received a final irrigation with 100 ml of the following irrigants that were activated with ultrasound for 3 minutes: Group 1- distilled water; Group 2- 0.2% chlorhexidine digluconate (CHX); Group 3- 2.5% sodium hypochlorite (NaOCl); and Group 4-the filtrate obtained after combining 0.2% CHX and 2.5% NaOCl. The apical portions of the root canals from each group were then submitted to histological processing and analyzed using optical microscopy.

Results
Results showed statistical differences between the groups (p<0.01). Groups 1 and 2 (distilled water and 0.2% CHX respectively) were statistically similar in terms of a greater amount of debris, whereas 2.5% NaOCl and the filtrate were more efficient in removal of debris.

Conclusion
There is no additional benefit in terms of debris removal from root canal walls by irrigating with the filtrate obtained from the combination of NaOCl and CHX when compared to using NaOCl alone.

Clinical Significance
The findings of this study suggest the time and expense of preparing and using a combination of NaOCl and CHX is not warranted compared to using NaOCl alone for root canal irrigation.

AimThe purpose of this study is to determine the efficacy of egg white in maintaining the viability of human periodontal ligament (PDL) cells on avulsed teeth.Methods and MaterialsThe experimental media were: egg white, milk, Hanks’ Balanced Salt Solution (HBSS) as the positive control, and tap water as the negative control. The storage times were 1, 2, 4, 8, and 12 hours. Extracted premolar teeth of healthy individuals were rinsed in the media. After trypsinization and subsequent treatment in collagenase, cell viability was determined using trypan blue staining. The two-way analysis of variance (ANOVA) statistical test was used to compare the results among different media.ResultsThere was no difference in the cell viability between egg white and HBSS media, but there was a statistically significant difference between the viability of PDL cells in egg white medium in comparison with milk (P<0.05) and water (P<0.05).ConclusionEgg white could be suggested as a suitable storage medium. Its principle advantage is its availability.CitationKhademi AA, Saei S, Mohajeri MR, Mirkheshti N, Ghassami F, Torabi nia N, Alavi SA. A New Storage Medium for an Avulsed Tooth.

Periodontal Abscess during Supportive Periodontal Therapy: A Review of the Literature
Authors: Silva Geraldo L. M. , Soares Rodrigo V. , Zenóbio Elton G. 
Published: July 2019

Aim
The aim of this review is to present the current status of the occurrence and management of a periodontal abscess during supportive periodontal therapy (SPT).

Background
A periodontal abscess depicts typical features and has been described in patients under SPT in clinical trials. Common periodontal pathogens have been observed in this lesion and some etiologic factors may be responsible for its recurrence. This condition can be isolated or associated with factors that can change the prognosis of affected teeth.

Review Results
Although it has been frequently noticed in untreated periodontitis, the periodontal abscess can also occur in patients under SPT and has been regarded as one of the possible complications of SPT. Patients with a high susceptibility to periodontal disease lost more teeth than those with a healthy periodontium.

Conclusion
Early diagnosis and appropriate intervention for periodontal abscesses in patients under SPT are extremely important for the management of the periodontal abscess since this condition can lead to loss of the involved tooth. A single case of a tooth diagnosed with periodontal abscess that responds favorably to adequate treatment does not seem to affect its longevity.

Clinical Significance
An accurate diagnosis and adequate treatment can preserve the longevity of affected teeth.

Published: July 2019

AimThe aim of this report is to present the etiology, diagnosis, and treatment planning strategy in the presence of an open gingival embrasure between the maxillary central incisors.BackgroundThe open gingival embrasure or “black triangle” is a visible triangular space in the cervical region of the maxillary incisors. It appears when the gingival papilla does not completely fill in the interdental space. The space may occur due to: (1) disease or surgery with periodontal attachment loss resulting in gingival recession; (2) severely malaligned maxillary incisors; (3) divergent roots; or (4) triangular-shaped crowns associated with or without periodontal problems and alveolar bone resorptions.ReportThe post-treatment prevalence in adult orthodontic patients is estimated to be around 40% compromising the esthetic result.ConclusionSeveral methods of managing patients with open gingival embrasure exist, but the interdisciplinary aspects of treatment must be emphasized to achieve the best possible result. The orthodontist can play a significant role in helping to manage these cases.Clinical SignificanceVarious treatment strategies are available to treat cases of an undesirable black triangle and are dependent on the etiology of the condition.CitationTanaka OM, Furquim BD'A, Pascotto RC, Ribeiro GLU, Bósio JA, Maruo H.

Authors: Akbari Majid , Ghavamnasiri Marjaneh , Hajizadeh Hila , Abedini Sara 
Published: July 2019

Aim
The aim of this randomized, double blind clinical trial was to compare three lining materials (Adper Prompt L-Pop, VivaSens, and Copalite) versus unlined restorations on postoperative cold sensitivity of class I amalgam restorations.

Methods and Materials
Potential subjects were screened for the presence of four initial class I carious lesions on posterior teeth. Each tooth was assigned to treatments according to a randomized block design. After cavity preparation, teeth were lined with either VivaSens, Adper Prompt L-Pop, or Copalite, and one tooth remained unlined and served as a control. The cavities were filled with high copper amalgam (Oralloy). The time taken for a subject to respond to a standardized cold stimulus (CRM) was recorded at baseline, 24 hours, one week, and one month after treatment. Participants filled out a self-report questionnaire at each time point. Data was gathered by analysis of variance (ANOVA) and Duncan Multiple Comparisons tests (α=0.05).

Results
Twenty subjects participated in this study. Comparisons within each group found no significant reduction in mean CRM for the Adper Prompt L-Pop group (P>0.05), but a significant difference in mean CRM for the VivaSens group was observed at one week and one month intervals after restoration (P<0.05). Copalite and the unlined groups showed significant mean CRM reductions after one day (P<0.05). No significant differences between groups receiving Adper Prompt L-Pop and Copalite were found at any time point (P>0.05). VivaSens showed more cold sensitivity than Adper Prompt L-Pop at one week and one month recalls (P<0.05), while the most cold sensitivity was found in the unlined group.

Conclusion
Adper Prompt L-Pop and Copalite reduced postoperative sensitivity to cold more than VivaSens and unlined groups at all assessment time points, 24 hours, one week, and one-month post treatment. The subjects receiving Copalite, VivaSens, and unlined restorations experienced greater sensitivity to cold at one month compared to baseline, while subjects receiving the Adper Prompt L-Pop liner experienced no greater sensitivity to cold from baseline to one month.

Clinical Significance
Adper Prompt L-Pop as a liner under spherical high copper amalgam successfully reduced cold postoperative sensitivity.

ABSTRACT
Calcium channel blockers are one of the most commonly used drugs for the management of cardiovascular disorders and are known for causing gingival over growth as adverse effects. Now a days, a new drug in this family Amlodipine, is being widely used, because of its duration of action. But it is of concern to the dental practitioner that this drug too has a similar effect on gingival tissues. This paper aims at drawing the attention of dentists towards the adverse effects of amlodipine along with providing a brief review of the pharmacologic profile of this drug, its effects on the gingiva and the management of hyperplasia.
Genetics – Need to Evaluate its Role in Early Detection of Oral Squamous Cell Carcinoma (OSCC)
Authors: Singla Urvashi , Kulhari Snehlata 
Published: July 2019

ABSTRACT
The concept of cancer genetics is relatively new and considered more in prostate and breast cancer. Its role in OSCC has never been given much attention, which is the sixth most common malignancy worldwide. It is a tumour which can be treated by simple surgical procedure, if diagnosed at an early stage. Oral cavity and oropharynx are easily accessible for visualization. But high prevalence of oral abnormalities (5-15%) detected as a result of oral screening programmes (OSP) subjects large number of patients for biopsy which is impractical. Detection of early stage oral cancer is significantly impaired by absence of classic clinical characteristics of advanced oral cancer in early stage lesions. This influences 5 year survival rate for 80% of patients, despite major advances in surgery, chemotherapy, radiotherapy.
Many gene alterations have been implicated in development and progression of OSCC. Genetic differences is an important consideration to determine individual differences in susceptibility to chemical carcinogens. Many genetic changes are commonly observed in oral cancers. Salivary Transcriptome Diagnostics, based on specific mRNA signature in saliva as diagnostic marker, can be a suitable tool for development of non invasive diagnostic, chemoprevention, prognostic and follow up tests for cancer and also to detect cancer conversion of premalignant lesions. To summarize research on genetics will open new directions for estimation of risk of human cancer and its early diagnosis.

Published: July 2019

ABSTRACT
We present a case of a 6 year old boy with a history of soft tissue injury caused by a toothbrush, the snapped head of which lodged into the medial aspect of the right ramus of the mandible. A survey of literature confirms that most injuries of this kind can be treated conservatively; however careful assessment by an experienced clinician is necessary to rule out other complications. The present paper discusses the prevalence, management and complications associated with impalement injuries of the oral cavity in children.
