In therapeutically anticoagulated patients tooth extractions can be safely performed without altering the dose of anticoagulant medication if efficient local hemostasis is provided. In most cases; in patients with INR ≤ 3.0 after extraction of one or two teeth postoperative bleeding can be controlled with local pressure, without any additional local hemostatic measures.
Background: Hyaluronic acid is widely used in the medical field. However, there is a lack of research about its effect on patients with certain risks, such as compromised wound healing commonly found in patients with poorly controlled type 2 diabetes. The aim of this study is to investigate the efficacy of hyaluronic acid on the post-extraction wound healing and pain in patients with poorly controlled type 2 diabetes. Material and Methods: The randomized controlled split-mouth study was designed, which included 30 patients with poorly controlled type 2 diabetes with a bilaterally same teeth in the lower jaw for extraction. The sockets treated with 0.8% hyaluronic acid represented the study group, while the sockets where hyaluronic acid was not applied represented the control group. Wound closure rate (WCR), clinical scores in wound healing scale (WHS) and pain intensity in Visual analogue scale (VAS) were recorded. Patients were followed up on 5 th , 10 th , 15 th , 20 th , 25 th day after tooth extraction.
A quality local anesthesia is one of the imperatives of performing dental interventions, and especially oral-surgical interventions, where the success of the oral-surgical intervention is seen through the success of local anesthesia. There is a high number of different local anesthetic solutions (LAS) on the market, holding different levels of vasoconstrictors which are attributed with causing numerous complications during the local anesthesia. The aim of this research is to point out the temperature changes caused by different LAS, depending on the strength and the concentration of LAS, using thermal vision camera. Testing was performed on 70 experimental Wistar rats, aged 4.5 months, with an average weight of 250 grams, male, and divided into seven groups of 10 animals each, depending on the applied anesthetic. After injecting the anesthetic solution into the haunch area, a stopwatch was turned on and control measurements were conducted for a period of two hours. All footage from the thermal camera was later transferred to a computer unit. Occurrence of multiple temperatures in the rats’ examined regions, compared to the control region, was noticed only when applying 2% pure lidocaine (without vasoconstrictors). The highest temperature drop, compared to the control region, was noticed with 2% mepivacaine with adrenaline (1 : 100 000), and 2% mepivacaine with noradrenaline (1 : 100 000), fi ve minutes after applying the local anesthetic. In conclusion: vasoconstricting effects are most expressed in the fi fth minute after applying LAS, and there are minimal differences between the effects of adrenaline and noradrenaline, in the examined combinations together with LAS.
Historical data on closing and suturing of surgical wounds describe a wide range of various suture materials. The choice of the surgical catgut, i.e. the type and diameter, depends on the locality, characteristics and condition of the tissue to be treated. From the standpoint of oral-surgical practice the following clinical parameters are of outstanding importance with respect to the selection of suture material: accumulation of soft deposits on the sutures, score of the adjacent soft tissues and dehiscence of the operative wound. Our prospective clinical study included 150 patients distributed into three groups of 50 subjects. The surgical procedure performed on each patient involved resection (apicotomy) of the tooth root end in the intercanine sector of the upper jaw. The following suture materials were applied: Black Silc 5-0, Nylon 5-0 and Vicryl 5-0. The effects of the selected sutures were evaluated according to the wound dehiscence. The effects of the applied sutures were recorded on Days 2, 5 and 7 after the surgery. The comparison of cited parameters of the investigated materials after suturing the oral mucosa revealed that none of the used material was ideal; however, a certain advantage might be given to the synthetic monofilament suture materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
