## 4 Discussion
Although there is a limit of subjectivity related to what the patient feels which cannot be avoided, the decrease of pain intensity after irrigation was recorded for all patients with values of one, two, three, to four points on the pain scale. BBE achieved statistically significant values, with most patients reporting a decrease of pain intensity of 4-5 points on the universal pain rating scale. Patients treated with CHX and BBE + CHX had decreases in pain intensity of one, two, and three points each on the pain scale. Compared to other similar studies [6], 68% patients treated with CHX irrigations reported pain relief. Irrigation with BBE resulted in reduction of trismus for 85% of patients. On the other hand, for 25% of the patients, the associated pain was completely relieved. In case of irrigations using the mixed solution of BBE and CHX (ratio 1:1), the decrease of pain was similar to that of the group irrigated with CHX, and the trismus values decreased considerably, although 25% of the patients did not register improvements. This may be due to the fact that BBE has an antibacterial and analgesic effect. In the case of chlorhexidine, the antiseptic effect is well-known in the medical field, the antibacterial and anti-inflammatory effect, and the results obtained after the irrigations were materialized in a decrease of the values with different intensities on all levels, for all patients and all parameters: pain, bleeding, and trismus. Additionally, the mixture of chlorhexidine and BBE proved by the results that it maintained the antiseptic effect of chlorhexidine, and the properties of BBE maintained an antibacterial and anti-gingival inflammation effect. Starting from the already existing evidence [25] supporting the effectiveness of CHX in the control of microbial plaque, gingivitis, and the symptomatic management of some infections of the oral cavity, we observed that in the case of pericoronitis it confirmed both its effectiveness and its limits. In this context, our study aimed to demonstrate the efficacy of BBE in the primary treatment of pericoronitis of the lower third molar and to compare the effects of this extract with chlorhexidine. We highlighted the beneficial effects of the BBE in the pathology of the eruption of third lower molars, more specifically in the case of pericoronitis, obtaining satisfactory results that were slightly superior to the chlorhexidine solution. The results confirmed the effectiveness of BBE used in the treatment of congestive pericoronitis and open prospects for further use in field of dental medicine as a possible primary treatment in pericoronitis with or without the intake of an antiseptic chemical solution such as chlorhexidine and for the treatment of other oral pathologies. Of course, further studies are needed to deepen and characterize the effects on different types of microbial cultures and to establish the limits of effectiveness, and as with CHX, depending on the situation, the benefits should always be weighed against the disadvantages (see anaphylactic reactions to CHX, rare but still present and tooth staining). Even if the effectiveness of CHX in controlling microbial plaque is demonstrated and accepted both in theory and in practice, in areas such as the prevention or treatment of certain conditions such as dental caries, chronic marginal periodontitis, and post-extraction alveolitis, the effectiveness is less proven [14], and a variant of applying an alternative treatment with a natural antiseptic can be a solution. Most of the patients involved in the study had a positive response to the presented treatment options, were cooperative, complied with the indications received during the study, and had a positive and open attitude regarding the availability of participation in this clinical study. Most of them were pleased that no antibiotics were used. Some patients were also not satisfied with the results obtained after the treatment, although they confidently participated in the study.
