This paper reports the nonsurgical endodontic therapy using calcium hydroxide intracanal dressing and prosthetic treatment of 9 teeth with periapical lesions in a 16-year-old female patient. The periodontal treatment plan included oral hygiene instructions, mechanical debridement and gingivectomy in the maxillary incisors to improve gingival contouring. Root canal treatment was indicated for teeth 11-13, 21, 22, 42-45. After successive changes of a calcium hydroxide intracanal dressing during 6 weeks, the size of the periapical radiolucencies decreased and lesion remission occurred after root canal obturation. The endodontically treated teeth received a bondable polyethylene reinforcement fiber (Ribbond) in the prepared canal space and crown buildup was done with composite resin. Prosthetic rehabilitation was planned with single-unit metal-ceramic crowns and fixed partial dentures. Clinical and radiographic evaluation after 6 months showed successful results. The outcomes of this case showed that chronic periapical lesions can respond favorably to nonsurgical endodontic treatment in adolescent patients and that, with proper indication, polyethylene fibers can provide an effective conservative and esthetic option for reinforcing endodontically treated teeth undergoing prosthetic rehabilitation.

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.

Although the use of periodontal dressings is currently limited, there are some indications for their use. Selection of any material that will have direct contact with live tissues, such as periodontal dressings, should be careful in order to allow surgical wound healing. The aim of this study was to evaluate the intensity of inflammatory response and bone formation in tooth sockets of rats after implantation of three periodontal dressings. After removal of the right maxillary incisors of 84 male rats, each tooth socket received implantation of a polyethylene tube, 63 of which were filled with non-eugenol periodontal dressing and the remaining 21 tubes remained empty (control group). Histological evaluation assessed the intensity of inflammatory response and presence and location of bone tissue formation at postoperative periods of 7, 14 and 28 days. Statistical analysis was performed by the Kruskal-Wallis test at 5% significance level. Regarding the inflammatory infiltrate, at 28 days, there was statistically significant difference between one of periodontal dressings and control group (p<0.05). Analysis of postoperative periods, showed that the control group presented statistically significant reduction in the inflammatory infiltrate comparing the 14- and 28-day periods (p<0.05). Regarding bone tissue formation, there was difference in control group between the 7- and 28-day periods (p<0.05). Within the experimental conditions, it may be concluded that no differences were found in the inflammatory response among the groups at 7 and 14 days and that Voco pac dressing induced a more intensive inflammatory reaction at 28 days.

INTRODUCTION
Complicated crown- root fractures, extended caries and iatrogenic destruction often result in insufficient sound tooth structures and compromise the biologic width. Two common options for re-establishing flap with osseous surgery. Although some advantages are related to these two options, but coronal movement of gingival and alveolar bone in orthodontic extrusion, esthetic problem and inconsistent topography between the involved tooth and the adjacent teeth following osseous surgery are the involved tooth and the adjacent teeth following osseous surgery are the major disadvantages of these two approaches. The purpose of this investigation was to evaluate clinically as well as radiographically the effect of surgical extrusion upon the surrounding root structures.
MATERIALS AND METHODS
The material consisted of 21 developed single roots (1 upper and 3 lower) surgically extruded in 17 patients (15 male and 2 female mean age 26 years, ranging 10-40). The indication for surgical extrusion was in 15 cases complicated crown root fracture and in 6 cases early loss of the crown due to an extensive decay. The roots were used where there were completed root developments and the apical fragments were long enough to accommodate a post retained crown. Preoperative radiograph as well as photograph was taken and the clinical and radiographic findings were monitored. The roots were transplanted in their socket in order to reestablish the biologic width. Fixation was carried out with a suture splint and/ or periodontal dressing for 7 days. Recall radiographs were taken at 1 and 4 weeks and at 3 month internals over a 12- month period.
RESULTS
Clinically none of the material of 21 teeth demonstrated ankylosis, abnormal mobility and sensibility to percussion or palpation radiographically, PDL healing at 12- month follow up was found in 20 teeth (95.2%).
CONCLUSION
successful results up to the time of evaluation encouraged further use of surgical extrusion. Long term evaluation is recommended.

This report presents a case of a completely intrusive luxation of an immature permanent central incisor in a 7 years 9 months-old girl. Because there are severe intrusive trauma and cortical alveolar bone fracture, it was impossible to reposition with orthodontic or surgical method alone. The intruded tooth was repositioned to healthy alveolar bone level by using surgical extrusion and stabilization with sutures and periodontal pack. After healing of adjacent bone, the intruded maxillary central incisor erupted orthodontically by removable orthodontic appliance. It was moved from a high position to level of adjacent tooth in about 7 months. A radiograph was taken 6 months after ceasing forced eruption, which demonstrated minor root resorption, but the alveolar bone height had increased.

A selected population of children with disabilities in Melbourne, Australia, was studied with reference to their oral disease and treatment needs. A total of 300 children (aged 9-13 years), 150 attending special developmental schools (SDS) and 150 attending special schools (SS), received an oral examination and the parent/guardian completed a questionnaire. Six levels of function were defined, based on the child's independence for five self-care activities (brushing teeth, feeding self, dressing self, walking and performing toilet). The caries experience of children in the SS was lower than in SDS (d + D: 1.3 +/- 1.6 versus 1.5 +/- 2.4; dmft + DMFT: 2.0 +/- 2.3 versus 2.5 +/- 3.1); those attending SDS had higher unmet preventive and restorative needs. Significant associations were seen between the number of decayed teeth, the dmft + DMFT index, and the level of function (p < 0.005). Periodontal disease was prevalent; significant associations were seen between periodontal status, the need for periodontal therapy, and the level of function (p < 0.005). Assessment of the level of function by staff could assist in triaging individuals for urgent dental examination. Despite 41 per cent of children requiring simple treatment, the preventive and treatment needs of many remained unmet. Following examination, diagnosis and treatment planning by a dentist, much of the preventive, simple treatment and oral health promotion could be performed by trained dental auxiliaries. An epidemiological survey followed by the implementation and evaluation of a long-range public dental health care plan for children and adolescents with disabilities is needed urgently.

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.
