BACKGROUND
Advances in bonding techniques and materials allow for reliable bracket placement on ectopically positioned teeth. This prospective study evaluates the outcome of forced orthodontic eruption of impacted canine teeth in both palatal and labial positions.
METHODS
Eighty-two impacted maxillary canines in 54 patients were included in the study and were observed for 18 to 30 months after exposure. Following exposure by means of a palatal flap or an apically repositioned buccal flap, an orthodontic traction hook, with a ligation chain attached, was bonded to each impacted tooth using a light cured orthodontic resin cement. A periodontal dressing was placed over the surgical site for a period of time.
RESULTS
All teeth were successfully erupted. Complications consisted of: failure of initial bond, at the time of surgery, which required rebonding; premature debonding at the time of pack removal and; debonding of brackets during orthodontic eruption. There was no infection, eruption failure, ankylosis, resorption or periodontal defect (pocket greater than 3 mm) associated with any of the exposed teeth. Attached gingiva of less than 3 mm was seen in only two of the buccally positioned canines (9%).
CONCLUSION
Forced orthodontic eruption of impacted maxillary canines with a well bonded orthodontic traction hook and ligation chain, used in conjunction with a palatal flap or an apically repositioned labial flap, results in predictable orthodontic eruption with few complications.

Assessment of Regeneration of Bone in the Extracted Third Molar Sockets Augmented Using Xenograft (CollaPlug Zimmer) in Comparison with the Normal Healing on the Contralateral Side.
INTRODUCTION
Alveolar bone resorption is a significant clinical problem. Bone loss in third molar region following extraction or surgical removal not only leads to periodontal problems in second molar region but also it may lead to some serious problems like increased incidence of angle fractures. In order to reduce the risks following third molar surgery, the socket should be augmented with bone grafts. In recent days guided tissue regeneration is the most accepted and successful technique followed many authors and its efficacy has been proved.
MATERIALS AND METHODS
Based upon our clinical experience, the use of bio absorbable collagen wound dressing such as CollaPlug has achieved quick healing and more primary wound coverage. Amongst the graft materials collagen is preferable due to its high biocompatibility and hemostatic ability. This study was done to assess the regeneration of bone in the extracted third molar sockets using xenograft (CollaPlug-Zimmer) which was compared with the normal healing on the contra lateral side. The assessment was done to analyze post-operative healing complications and to compare the bone density formed between control site and implant site radiologically.
CONCLUSION
On this basis of this study, the use of collaplugTN appears to be beneficial to the patient in postoperative wound healing and also for better bone formation. The use of this material was advantageous because of its simplicity of application cost effectiveness and availability. There is enhanced wound healing and early bone formation.

BACKGROUND
Minimally invasive techniques for lumbar discectomy have been recommended as superior to open techniques due to lower blood loss, lower rates of infection and shorter recovery. There are, however, concerns that this approach does not sufficiently remove the herniated nuclear material, thus leaving the patient susceptible to reherniation requiring reoperation. The purpose of this study was to examine the safety and viability of an annular closure device in limiting reherniation and reoperation in a cohort of patients undergoing minimally invasive lumbar discectomy with the assistance of an annular closure device.
METHODS
We retrospectively analysed the results from patients treated by a single surgeon between March 2011 and December 2017. All patients had been diagnosed with a large (≥ 5 mm) defect and were treated via minimally invasive surgical techniques. Outcomes included demographic data, the procedural duration and the rates of symptomatic reherniation and reoperation.
RESULTS
60 patients were included in the study. The mean age was 42 years (range: 19-66); mean BMI was 24.1 (range: 16.7-36.3). Mean surgical duration was 29 min (range: 16-50). Reoperation was required in 5% (3/60) of patients, although only 3% (2/60) experienced symptomatic reherniation at the index level. No other complications were reported.
CONCLUSIONS
In our study, the use of an annular closure device during minimally invasive lumbar discectomy in a population of patients with large herniations was associated with low rates of reherniation and reoperation at the index level. While more research is required, the results of this study demonstrate the safety and viability of the annular closure device as an adjunct to minimally invasive discectomy.

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.

Clinical Trial
INTRODUCTION
Dentin hypersensitivity (DH) is a painful tooth condition affecting a large proportion of the world population. While DH is not a direct cause of tooth loss, it does cause discomfort and stress. DH treatment methods include desensitizers, such as fluoride compounds; polycyanoacrylate coating; low intensity laser therapy; and surgery as a last resort. In Cuba, a fluoride varnish, Profilac, is widely used with acceptable results. Tisuacryl, an N-butyl-2-cyanoacrylate-based tissue adhesive is licensed in Cuba as a medical device used for closing wounds and as a protective covering or dressing for oral tissues. Experimental use of Tisuacryl in DH treatment has begun recently with good results.
OBJECTIVE
Evaluate the effectiveness and safety of Tisuacryl in treating dentin hypersensitivity.
METHODS
An experimental, prospective, longitudinal, multicenter, non-controlled clinical investigation was conducted using the licensed medical device Tisuacryl. The study universe consisted of patients with DH symptoms who sought treatment at three dental clinics in Havana Province between May 2007 and February 2009. The sample consisted of 152 patients who met inclusion and diagnostic criteria for the study. DH was classified as severe, moderate, or mild. Remission of dentinal pain was the principal variable for evaluating effectiveness. Safety variables were mucosal irritation and burning sensation at the treatment site. Treatment was considered successful if DH was cured, defined as remission of pain and relief of discomfort (irritation or burning sensation) with no other adverse events by the final evaluation on day 6 after treatment initiation.
RESULTS
Tisuacryl treatment was successful in 96.7% of patients (81.5% with severe DH and 100% with mild to moderate DH). Mucosal irritation was observed in only 1 patient at first evaluation on day 2 but disappeared by the second evaluation. No other adverse events were reported.
CONCLUSIONS
Tisuacryl was shown to be an effective, safe treatment of dentin hypersensitivity, especially moderate and mild cases.

INTRODUCTION
The objective of this study was to investigate the expression of matrix metalloproteinases (MMPs) in apical periodontitis and during the periapical healing phase after root canal treatment.
METHODS
Apical periodontitis was induced in dog teeth, and root canal treatment was performed in a single visit or by using an additional calcium hydroxide root canal dressing. One hundred eighty days after treatment the presence of inflammation was examined, and tissues were stained to detect bacteria. Bacterial status was correlated to the degree of tissue organization, and to further investigate molecules involved in this process, tissues were stained for MMP-1, MMP-2, MMP-8, and MMP-9. Data were analyzed by using one-way analysis of variance followed by Tukey test or Kruskal-Wallis followed by Dunn test.
RESULTS
Teeth with apical periodontitis that had root canal therapy performed in a single visit presented an intense inflammatory cell infiltrate. Periapical tissue was extremely disorganized, and this was correlated with the presence of bacteria. Higher MMP expression was evident, similar to teeth with untreated apical periodontitis. In contrast, teeth with apical periodontitis submitted to root canal treatment with calcium hydroxide presented a lower inflammatory cell infiltrate. This group had moderately organized connective tissue, lower prevalence of bacteria, and lower number of MMP-positive cells, similar to healthy teeth submitted to treatment.
CONCLUSIONS
Teeth treated with calcium hydroxide root canal dressing exhibited a lower percentage of bacterial contamination, a lower MMP expression, and a more organized extracellular matrix, unlike those treated in a single visit. This suggests that calcium hydroxide might be beneficial in tissue repair processes.

INTRODUCTION
The aim of this study was to compare the antibacterial effects of two gels containing zinc oxide and zinc oxide/silver nanoparticles and a mixture of calcium hydroxide and 0.12% chlorhexidine as intracanal medicaments in root canals contaminated with () at different time intervals.
METHODS AND MATERIALS
After preparation and culturing of in 132 single root teeth, the initial count of bacteria was performed. Then, different materials as intracanal medicaments were used in periods of 3, 7 and 14 days (group 1: calcium hydroxide with 0.12% CHX paste; group 2 zinc oxide nanoparticles gel; group 3: zinc oxide/silver nanoparticles gel; group 4: normal saline as the control group). After the specified time, intracanal medicament was removed and the final count of bacteria was performed. Antibacterial effect of materials was counted by measuring the percentage reduction in the colony counts (RCC). Data were analyzed using the descriptive statistics (Mean±SD) and multi-factorial analysis of variance (by taking into account the effect of the time factor on the dependent variable).
RESULTS
There were no statistically significant differences among mean RCC of different time intervals in each group (=0.09). However, the differences in mean RCC of different dressing materials were significant (<0.001). The effect of interaction between time and materials was significant (=0.015). Comparison of the antibacterial effects of experimental agents at different time intervals showed that the mean RCC in group 1 was higher than other groups (<0.001). The difference in antibacterial effect between groups 2 and 3 was not significant (>0.05). The minimum antibacterial effect was observed in group 4 (<0.0001).
CONCLUSIONS
The mixture of calcium hydroxide/chlorhexidine as an intracanal medicament was more effective than zinc oxide and zinc oxide/silver nanoparticles gels.

Periodontal plastic surgery often involves palatal donor site, thereby creating an open wound that is prone to postoperative complications such as bleeding, pain, and slow healing process. To prevent the same, platelet-rich fibrin (PRF) and gelatin sponge (GS) were utilized equally at the donor site in six patients. Patients were monitored at the 1, 2, 3, and 4 weeks after surgery for postoperative discomfort (D), consumption of analgesics during first postoperative week, alteration of sensitivity (AS), change in feeding habits (CFH), complete wound epithelialization (CWE), and healing index (Landry 1998). Two patients in the GS group showed significantly early CWE, higher healing index score, and less D, AS, and CFH postoperatively in comparison to the PRF group. It was suggested that GS can also be considered as an effective, economical, and biocompatible dressing material of choice to enhance wound healing and to minimize postoperative complications associated with the donor site.

BACKGROUND
Owing to its stimulatory effect on angiogenesis and epithelialization, platelet-rich fibrin (PRF) is an excellent material for enhancing wound healing. The use of PRF dressings may be a simple and effective method of reducing the morbidity associated with donor sites of autogenous free gingival grafts (FGGs). The purpose of this case series is to document the beneficial role of PRF in the healing of FGG donor sites.
MATERIALS AND METHODS
A total of 18 patients treated with FGGs could be classified into two groups. PRF was prepared, compressed and used to dress the palatal wound followed by a periodontal pack in one group (10 patients) and only a periodontal pack was used in the other group (8 patients). Post-operative healing was assessed clinically at 7, 14 and 21 days and the morbidity was assessed qualitatively by an interview.
RESULTS
Sites where PRF was used showed complete wound closure by 14 days and these patients reported lesser post-operative morbidity than patients in whom PRF was not used.
CONCLUSIONS
PRF as a dressing is an effective method of enhancing the healing of the palatal donor site and consequently reducing the post-operative morbidity.
