Because local anesthetics are vasodilators, they tend to be absorbed into the bloodstream from the operative field as a result of the vasodilation of peripheral arterioles. To counteract this vasodilation, vasoconstrictive agents are often included in local anesthetic solutions to provide a longer duration of anesthesia. Low-level laser therapy (LLLT) has the same benefits, such as microcirculation activation and more-efficient tissue metabolism, analgesic effects, and vasodilatation. If LLLT is used to prevent pain postoperatively, improvements in local circulation and increased vasodilatation may increase the absorption of a local anesthetic agent. This may reduce the duration of the anesthesia, thereby allowing postoperative pain management to begin sooner. The maximal intensity of pain occurs during the first hours after surgery, when the local anesthetic has worn off. Theoretically, postoperative pain control can be increased with the use of a local anesthetic with a more-prolonged action. If a treatment method has both analgesic and antianesthetic effects, then the method may block its own effects. We review whether LLLT applied postoperatively to operated-on areas has an antianesthetic effect, that is, whether pain in the first hours after surgery was greater for patients who received LLLT than for control patients. Not too much evidence supports the antianesthetic effects of LLLT. However, additional experimental and clinical studies must be performed to investigate the effects of LLLT on the duration of anesthesia.

Background The purpose of this study was to explore the effects of coronavirus disease 19 (Covid-19) on the oral cavity by evaluating the oral findings in the patients who recovered after treatment. Material and Methods This study involved confirmed Covid-19 patients whose treatment completed at least two weeks ago. A questionnaire consist of eight parts was applied to explore the oral findings after Covid-19. Also stimulated salivary flow rate was evaluated with a salivary flow test. Results 177 patients reached and 107 of them participate in the study. Regarding gender significant differences were found in terms of the presence of taste impairment after treatment ( p =0.007), the degree of taste ( p =0.021) and smell ( p =0.010) impairment. 18 % (5/27) of the patients evaluated were showed hyposalivation. No significant differences were observed regarding salivary flow between males (mean±SD: 1.14±0.65) and females (mean±SD: 1.12±0.43), ( p =0.928); among the patients having treatment at home (mean±SD: 1.03±0.48) or hospital (mean±SD: 1.33±0.65), ( p =0.187). In some of the patients’ taste [15], smell [23] impairment, and xerostomia [43] still observed at least two weeks after the treatment is completed. Conclusions The most frequent finding in patients after the treatment was xerostomia. Taste and smell impairments were more frequently observed in females. Key words: Saliva, oral findings, hyposalivation, Covid-19.

The aim of this study was to compare the stresses on cylindrical and conical dental implants under heavy bruxing forces, in D1 and D4 bone densities, using three-dimensional finite element analysis (FEA). Eight different stress models were created according to implant design (cylindrical or conical), bone density (D1 or D4) and load (1000 N, vertical or oblique). The von Mises stresses for each model were compared using FEA. The obtained results showed that D1 bone density and vertical force were associated with the least stress on the implant. Bone density was more important than implant design in stress formation. The results from the two implant types were very similar. The von Mises stress values were greater in the neck region of the implant. We suggest that the implant region should be considered firstly for less stress on the implant.

A single session of combined arthrocentesis and prolotherapy to treat symptomatic TMJ safely and significantly improved the subluxation and pain after 1 week and subluxation after 3 months compared to baseline status. The maximum mouth opening significantly decreased at all follow-up time points. Future studies assessing multiple treatment sessions are warranted.

Objective:Foreign bodies can be deposited in the oral cavity either by traumatic or iatrogenic injury. The most common foreign bodies of iatrogenic origin encountered are restorative materials, like amalgam, and root canal fillings. The aim of this study was to determine the prevalence of foreign bodies detected with panoramic radiography in the jawbones, as well as to evaluate the etiology and characteristics of these pathologies.Materials and Methods:From March 2012 to January 2014, 11,144 panoramic radiographs were taken and retrospectively reviewed. The number, characteristics, location of the foreign bodies, age, and gender of the patients were recorded.Results:Of the 11,144 patients reviewed, 62 of them have a foreign body with a frequency of 0.6%. The patients who had a foreign body were between 14 and 81 years old. Female patients showed more foreign bodies than male patients. Among the 62 patients, 63 filling materials, one stapler, and five shrapnel were detected. Only 8 patients had symptoms associated with foreign bodies and these foreign bodies excised surgically.Conclusion:If possible, these pathologies must be removed at the time of detection to prevent further complications; however, in asymptomatic cases, according to location and the characteristic of the foreign body, they can be kept under observation without performing any operations.
