Background/purpose Tooth extraction is often followed by a number of different complications that demand additional treatment. In order to accelerate healing processes and decrease the complication occurrence various agents, growth factors, natural and synthetic antioxidants (e.g coenzyme Q 10 -CoQ 10 ), are applied. Due to the partially known health-promoting effects of CoQ 10 we decided to assess potential of it's encapsulated in nanoliposomes form on wound healing process following tooth extraction. Materials and methods Effects of free and encapsulated form of CoQ 10 on wound healing processes after tooth extraction in rats, 3 and 7 days following surgical procedure, was studied by means of tissue biochemical (myeloperoxidase activity and nitric oxide (NO) concentrations) and pathohistological analysis. Results The obtained results indicate that the encapsulated form of CoQ 10 compared to control and CoQ 10 treated animals statistically significantly decreases inflammatory process estimated through myeloperoxidase activity and NO concentrations, as well as based on histopathological analysis 3 and 7 days following surgery. Conclusion The results of this study unequivocally prove that the encapsulation of CoQ 10 in nanoliposomes enhances CoQ 10 activity by accelerating wound healing process after tooth extraction.

Background/Aim. Lichen planus is a chronic, immunologic, mucocutaneous disease with a wide range of clinical manifestations. The aim of this retrospective study was to evaluate the most common forms of oral lichen planus (OLP) and its symptoms and to describe treatment responses in patients during 10-year period. Methods. The study was conduced on 163 OLP patients who came in the Department of Oral medicine and Periodontology between 1997 and September 2007. Each case was classified into one of four clinical subtypes: reticular, atrophic, erosive-ulcerative, bullous. Results. There was no significant difference in patients age. Women were found to be significantly more likely to have OLP (p < 0.001). Corticosteroids were effective in reducing symptoms, erythema and healing ulcers. Improvement was shown over a long term in 61.35% patients. Over the long term 38.65% patients maintained the same type of OLP or it became a more severe type. Two patients (1.22%) developed oral carcinoma during the follow-up period. Conclusion. The response of patients with erosive OLP to a short course of systemic corticosteroids often was quite remarkable. However, symptoms and signs tended to recur after this treatment. Periodic examinations, patient education, medical treatment, monitoring of side-effects as well as follow-up biopsies are necessary for management of OLP patients

Background: Perineurally adding dexamethasone to local anesthetics could enable postoperative analgesia. Our aim was to investigate the efficacy of 4 mg dexamethasone and 0.5% ropivacaine on the prolonged duration of mandibular anesthesia for postoperative analgesia during third molar surgery. Materials and method: The patients of both sexes, and in the age range of 17 to 50 yrs of age, received the Gow-Gates anesthesia. Group I received 4 mL of plain 0.5% ropivacaine, with perineurally added 1 mL/4 mg of dexamethasone; group II received 4 mL of plain 0.5% ropivacaine with perineurally added 1 mL of 0.9% saline; group III received 4 mL of plain 0.5 bupivacaine with perineurally added 1 mL of 0.9% saline. The prime anesthesia outcome was the duration of conduction anesthesia (DCA); the secondary outcome was the duration of analgesia (DAN) and analgesia before analgesic intake. Results: In 45 randomly selected subjects (mean age 27.06 ± 8.20), DCA was statistically longest in group I (n = 15) (592.50 ± 161.75 min, p = 0.001), collated with groups II (n = 15) and III (n = 15) (307.40 ± 84.71 and 367.07 ± 170.52 min, respectively). DAN was significantly the longest in group I (mean: 654.9 ± 198.4 min, p = 0.001), compared with group II (345.4 ± 88.0 min) and group III (413.7 ± 152.3 min), with insignificant adverse reactions. One-third of the operated patients absented from the use of analgesics. Conclusion: A amount 0.5% ropivacaine with dexamethasone usefully served as an analgesic with a success rate of 93.4% of the given anesthesia.

This study evaluated the effects of curcumin, a naturally occurring compound with numerous health-beneficial properties, on the wound-healing process of extraction sockets (soft tissue that surrounded the extracted tooth) in rats. The effects of topically applied curcumin were monitored by tracking changes in myeloperoxidase activity and nitric oxide concentrations in soft tissue homogenates 3 and 7 days following surgery. Additionally, pathohistological examination of tissue sections was used to reveal the effects of curcumin on the course of wound healing on a microscopic level. Compared to the untreated control, topically administered curcumin statistically significantly decreased soft-tissue myeloperoxidase activity and nitric oxide concentrations after both 3 and 7 days of application. Microscopic analysis showed a reduced inflammatory infiltrate (subjectively and morphometrically estimated as the number of polymorphonuclear cells/100 μm 2) and an increased collagen deposition in rats treated with curcumin. The obtained results point to the great potential of curcumin in the acceleration of tooth extraction wound-healing processes partially through the reduction of the inflammatory response and increase in collagen deposition. Thus, these results significantly contribute to the previously suggested application of curcumin in the skin wound treatment by potentially broadening its usage in the treatment of mucosal wounds.

Uvod:Lokalni anestetici su najčešće korišćeni lekovi u svakodnevnoj stomatološkoj i medicinskoj, a sve češće i u kozmetičkoj praksi. Danas postoji veliki broj lokalnih anestetika koji su prema strukturi podeljeni na dve grupe: estarske i amidne lokalne anestetike. Iako je njihova primena u svakodnevnom radu uglavnom bezbedna, nije isključena mogućnost pojave negativnih reakcija koje mogu biti psihogene, toksične, imunološke i specifične neželjene reakcije. Cilj: ovog rada je da ukaže na mehanizam nastanka i simptomatologiju mogućih negativnih reakcija na lokalne anestetike. Zaključak:Ukoliko dođe do pojave sistemske neželjene reakcije na lokalni anestetik, najveći problem, u kliničkoj praksi, predstavlja prepoznavanje prirode negativne reakcije i pružanje adekvatne terapije u vezi sa nastalom reakcijom.Brzina i sigurnost u prepoznavanju neželjene reakcije na lokalni anestetik, nekada mogu biti od životnog značaja za bolesnika. AbstractIntroduction: Local anesthetics are the most commonly used drugs in everyday dental and medical and increasingly in cosmetic practice. Today there are a number of local anesthetics that are divided into two groups based on their structure: ester and amide local anesthetics. Although their use in everyday work is generally safe, there is a possibility of adverse reactions that may be psychogenic, toxic, immunologic and specific adverse reactions. The aim of this work is to highlight the mechanism of occurrence and symptoms of possible adverse reactions to local anesthetics. Conclusion: If you experience systemic adverse reactions to the local anesthetic, the biggest problem in clinical practice, is a recognition of the nature of adverse reactions and providing appropriate therapy in conjunction with the resulting reaction. Speed and security to identify adverse reactions to local anesthetic can be of vital importance for the patient.
