BACKGROUND
Periodontal dressings have been used for several years as a protection over injured tissue to shield the area from further insult. Several dressings are commercially available. A recently introduced light-cured resin, claimed to be more biocompatible and esthetic, needs critical evaluation.
AIM
To compare this dressing with most widely used non-eugenol pack in the perspective of esthetics, acceptance, and healing following periodontal flap surgery.
MATERIALS AND METHODS
Twenty patients suffering from generalized chronic periodontitis, requiring periodontal flap surgery on contralateral sides of the arch, were selected and divided randomly into Group I (control) and Group II (test). In Group I, a non-eugenol dressing and in Group II light-cured dressing were applied after flap surgery. Pain and discomfort scores were recorded on day 1, 2, and 3 while plaque scores, gingival index, and bleeding index were recorded on day 7. Patient's subjective evaluation and preference for the dressing material were recorded. The data was collected and statistically analyzed.
RESULTS
Group II showed better results than Group I when plaque scores, bleeding scores, modified gingival index scores, and pain and discomfort scores were compared though the differences were not statistically significant. Subjects found no unpleasant taste/smell and perceived the light-cured dressing to be better. A significantly higher number of patients preferred light-cured resin as a post-surgical dressing over Coe-pak.
CONCLUSION
The light-cured dressing showed better patient acceptability and proves to be a better alternative to Coe-pak as a dressing material.

The success of pulpotomy of young permanent teeth depends on the proper selection of dressing materials. This study aimed to evaluate the histological and histomorphometric response of dentin-pulp complex to the enamel matrix derivative (Emdogain(®) gel) compared to that of calcium hydroxide when used as a pulp dressing in immature young permanent dogs' teeth. Dentin-like tissues bridging the full width of the coronal pulp at the interface between the injured and healthy pulp tissues were seen after 1 month in both groups. With time, the dentin bridge increased in thickness for calcium hydroxide but disintegrated and fully disappeared for Emdogain-treated group. Progressive inflammation and total pulp degeneration were only evident with Emdogain-treated group. The root apices of Emdogain-treated teeth became matured and closed by cementum that attached to new alveolar bone by a well-oriented periodontal ligament. In young permanent dentition, Emdogain could be a good candidate for periodontium but not dentino-pulpal complex regeneration.

Journal of the American Veterinary... Feb 2014To evaluate factors associated with the outcome of vital pulp therapy (VPT) in dogs.
OBJECTIVE
To evaluate factors associated with the outcome of vital pulp therapy (VPT) in dogs.
DESIGN
Retrospective study.
SAMPLE
190 teeth in 138 dogs.
PROCEDURES
Medical records were reviewed; radiographs obtained before, immediately after, and during the last available follow-up examination for VPT were evaluated. Treatment was categorized as successful (with radiographic evidence of continued secondary dentin production, continued root formation in immature teeth, and absence of clinical and radiographic signs of apical periodontitis and internal or external inflammatory root resorption), having no evidence of failure (with signs for success fulfilled except the width of the apical periodontal ligament space, which could be wider than but no more than double the width of the periodontal ligament space in other areas), or failed (with radiographic evidence of pulp necrosis, apical periodontitis, or inflammatory root resorption). Associations between diagnostic or treatment-related variables and outcome were assessed with multinomial logistic regression.
RESULTS
Overall, treatment was classified as successful for 162 of 190 (85%) teeth, including 23 (12%) teeth with no evidence of failure, and as having failed for 28 (15%) teeth. The overall success rate was 137 of 149 (92%) for teeth treated with mineral trioxide aggregate alone and 21 of 36 (58%) for teeth treated with Ca(OH)2 alone. Use of Ca(OH)2 and deep penetration of dressing material into the vital pulp were each significantly associated with increased odds of treatment failure.
CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that VPT with mineral trioxide aggregate was an effective option for use in crown reduction to treat malocclusion and for treatment of recent crown fractures in immature or mature permanent teeth.

Eugenol is an active, principal aromatic liquid responsible for several pharmacological activities. It is widely used in dental practice to relieve pain arising from various sources, such as pulpitis and dentinal hypersensitivity. As a primary irritant and sensitiser, it is known to cause contact urticaria as well as chronic urticaria. However, eugenol causes allergic contact dermatitis, possibly because it can react directly with proteins to form conjugate and reactive haptens. It is found that eugenol in various dental preparations-especially in the case of some zinc oxide-contains preparations such as periodontal dressings and root canal cements. This can cause hypersensitivity when it comes in contact with gingiva or teeth. This article presents a case of immediate allergic contact urticaria to eugenol during dental treatment.

AIM
The objective of the present clinical study was to compare the effectiveness of radiofrequency de-epithelialization and conventional (slicing) method in reducing gingival pigmentation on long term basis by split mouth design.
MATERIALS AND METHODS
A total of 28 maxillary gingival units from 4 subjects aged between 15-30 years were considered for this clincal study and the selected gingival units were made plaque free and clinically healthy before subjectiing these sites to one of the procedures. The selected sites were abraded by either the conventional (slicing) method (14 gingival units of 21, 22, 23, 24) or by radiofrequency (14 gingival units of 11, 12, 13, 14). After the procedure periodontal dressing was applied to protect the operated area. After 1 week periodontal dressing was removed and the area was irrigated with saline. Follow up examination was done on 30(th), 60(th) and 90(th) days to evaluate the recurrence of pigmentation, if any.
RESULTS
It was obsereved that, sites operated with conventional (slicing) method, showed higher mean pigmentation than the sites treated with the radioablation during the follow up period of 90 days.
CONCLUSION
When used judiciously, radiofrequency can be clinically valuable, safe and effective method to reduce pigmentation of gingiva.

Bleeding is a common sequela of oral and periodontal surgery. Generally, bleeding is self-limiting. Following traumatic injury or surgical procedures, hemorrhage can range from a minor leakage or oozing at the site, to extensive bleeding leading to complete exsanguinations. Significant postsurgical hemorrhage following periodontal surgery is uncommon due to the primary closure of the soft tissues. This case report describes the unique formation of a "liver clot" or "currant jelly clot" following periodontal flap surgery. The likelihood of this may be attributed to many factors, like infection, intrinsic trauma, presence of foreign bodies like splinter of bone, a fleck of enamel, or a piece of dental restorative dressing material that may cause repeated, delayed organization of blood coagulum.

This paper describes and discusses the multidisciplinary treatment involving a permanent maxillary lateral incisor fused to a supernumerary tooth, both presenting pulp necrosis and periapical lesion. A 15-year-old male patient sought treatment complaining of pain, swelling and mobility on the maxillary right lateral incisor. After clinical and radiographic examination, root canal preparation was performed according to the crown-down technique and a calcium hydroxide dressing was placed for 15 days. The patient returned and the definitive endodontic filling was done with thermomechanical compaction of gutta-percha and sealer. After 18 months, clinical and radiographic examinations were carried out and no pain or swelling was reported. Two years after endodontic treatment, the patient returned for periodontal and cosmetic treatments. Nine months later, a cone-beam computed tomography (CBCT) revealed that the previously detected periodontal defect and periapical lesion were persistent. Apical endodontic surgery was indicated. The supernumerary tooth was removed, the communicating distal surface was filled and the surgical site received bioactive glass and demineralized bovine organic bone. The pathological tissue was submitted to histopathological examination and the diagnosis was periapical cyst. One year after the apical endodontic surgery, CBCT showed bone formation at maxillary lateral incisor apical area. Two years after the surgery, the restoration was replaced due to aesthetic reasons and periapical radiograph showed success after 5 years of treatment. A correct diagnosis and establishment of an adequate treatment plan resulted in a successful management of the case.

By mimicking the native extracellular matrix, electrospun nanofibrous scaffolds (ENSs) can provide both chemical and physical cues to modulate cell adherence and differentiation and to promote tissue regeneration while retaining bioresorbable and biocompatible properties. In this study, ENSs were developed to deliver multiple biomolecules by loading them into the core-sheath structure and/or by conjugating them to the nanofiber surfaces. In this work, poly(L-lactide)-poly(ethylene glycol)-NH(2) and poly(L-lactide) were emulsion electrospun into nanofibers with a core-sheath structure. A model drug, tetracycline hydrochloride, was loaded within the nanofibers. Amino and carboxyl reactive groups were then activated on the fiber surfaces using saturated water vapor exposure and base hydrolysis, respectively. These reactive groups allowed the surface of the ENS to be functionalized with two other bioactive molecules, fluorescein isothiocyanate- and rhodamine-labeled bovine serum albumins, which were used as model proteins. The ENSs were shown to retain their antimicrobial capacity after two functionalization reactions, indicating that multifunctional nanofibers can potentially be developed into functional wound dressings or periodontal membranes or used in more complicated tissue systems where multiple growth factors and anti-infection precautions are critical for the successful implantation and regeneration of tissues.

BACKGROUND
Individuals with human immunodeficiency virus (HIV) have an increased risk of developing health problems, including some that are life threatening. Today, dental treatment for the population with a positive HIV diagnosis (HIV+) is comprehensive. There are limited reports on the outcomes of intraoral surgical therapy in patients with HIV, such as crown lengthening surgery (CLS) with osseous recontouring. This report investigates the outcome of CLS procedures performed at an urban dental school in a population of individuals with HIV. Specifically, this retrospective clinical analysis evaluates the healing response after CLS.
METHODS
Paper and electronic records were examined from the year 2000 to the present. Twenty-one individuals with HIV and immunosuppression, ranging from insignificant to severe, underwent CLS. Pertinent details, including laboratory values, medications, smoking history/status, and postoperative outcomes, were recorded. One such surgery is described in detail with radiographs, photographs, and a videoclip.
RESULTS
Of the 21 patients with HIV examined after CLS, none had postoperative complications, such as delayed healing, infection, or prolonged bleeding. Variations in viral load (<48 to 40,000 copies/mL), CD4 cell count (126 to 1,260 cells/mm(3)), smoking (6 of 21 patients), platelets (130,000 to 369,000 cells/mm(3)), and neutrophils (1.1 to 4.5 × 103 /mm(3)) did not impact surgical healing. In addition, variations in medication regimens (highly active anti-retroviral therapy [18]; on protease inhibitors [1]; no medications [2]) did not have an impact.
CONCLUSIONS
The results of this retrospective analysis show the absence of postoperative complications after CLS in this population with HIV. Additional investigation into this area will help health care practitioners increase the range of surgical services provided to this group of patients.

BACKGROUND
Free gingival grafts have been used extensively for gingival augmentation procedures, but are associated with postoperative morbidity because of the open palatal wound. This study compares the clinical efficiency of two dressing materials, a non-eugenol-based dressing (Coe-Pak™) and a collagen dressing (Colla Cote(®)) on palatal wound healing.
MATERIALS AND METHODS
Thirty-two patients in the age group of 25-50 years, who required gingival augmentation, were selected. Free gingival graft was harvested from the palatal mucosa and the wound was then protected using Coe-pak(®) in control group and Colla Cote(®) in test group. The subjective parameters pain and burning sensation were recorded on the 2(nd) and 7(th) day and the objective parameters colour and consistency were recorded on the 7(th) and 42(nd) day, using a visual analog scale. Thickness of the mucosa was measured using K file at baseline and 42(nd) day. Histological examination was done on 42(nd) day.
RESULTS
The subjective and objective parameters showed significant improvement in the test group when compared to control group. Histologically, there was a greater evidence of collagen formation and turn over in the test group than control group.
CONCLUSIONS
Collagen-based dressing may thus offer significantly greater advantages over the traditional non-eugenol dressings.
