    It is suggested that the analgesic effect of viscosupplementation may occur by blocking receptors and endogenous algic substances in the synovial tissues. A strictly mechanic mechanism by the interruption of trauma caused by mechanic block of the disk or of both adherence zones was also suggested [55], what could explain the effects of therapy in medium and long term, because although the injected HA is kept on the joint only for a few days the results last for months [56,57]. The study results of Yakan et al. [58] were in agreement with the present study as he estimated the efficacy of arthrocentesis and hyaluronic order (RS)-CPP injections for the treatment of temporomandibular joint osteoarthritis. Regarding mandibular functions, the present study results showed higher mouth opening values, lateral excursion movements and protrusive mandibular movement records in fentanyl group through different postoperative intervals. In accordance to current study, Hamed T [33]. compared arthrocentesis followed by COX-2 inhibitor versus tramadol in management of internal derangements of the tempromandibular joint. He concluded that intra-articular injection of tramadol which is one of opioids is effective in management of clinical symptoms as he found statistically significant increase in both the maximum mouth opening and the lateral excursion through all periods in COX-2 inhibitor and tramadol groups, as well as significant decrease in mean VAS however, tramadol showed a significant improvement in VSA, maximum mouth opening and lateral excursion superior to those of COX-2 inhibitor group.
    Conclusion
    Introduction Philipsen and Birn [1] proposed the designation of adenomatoid odontogenic tumor (AOT) which was, two years later, promoted by the World Health Organization. Adenomatoid odontogenic tumor (AOT), both in nature and in designation, is now questioned. Based on clinical and immunohistochemical findings, AOT was suggested to be a hamartomatous entity emanating from the reduced enamel epithelium [2]. Owing to its benign behavior, slow growth and clear delineation, as well as its low tendency to recur (0.2%), the treatment of choice is conservative surgical enucleation and simple curettage [3]. Later, AOT has eschewed the very usual pathway by appearing in collision with ameloblastic elements [4] and by integrating into the so-called adenoid ameloblastoma (AA) [5]. Moreover, AA trails a new pathway by its representation, as reported in this paper, peripherally in the retromolar pad area.
    Case presentation Histologically, atypical AOT areas with rosettes and duct-like structures were observed in a pool of ameloblastomatous lesion. Both were interspersing the salivary tissue of the retromolar pad. The lesion was unecapsulated and was surrounded by a normal histological architecture of the retromolar pad: fibrous, adipose and salivary tissues (Fig. 1). Both the ameloblast-like cells and duct-like structures manifested tall columnar epithelial cells. Interestingly, the lesion evinced occasional nuclear atypia, even some mitotic figures, and hyperchromatic tumor cells. Less significant, washed-out nuclei were conspicuous (Fig. 2). Although induction materials and cystic changes were evident in the atypical arrangements which recapitulated the appearance of AOT, the order (RS)-CPP classical eosinophilic materials, which are typically seen in AOT, were unremarkable (Fig. 3). Moreover, the tumoral cells were observed, intermittently and sporadically, interfering with the salivary architecture (Fig. 4). No necrosis was obvious. The cellular atypia could not prove to promote a malignancy. The specimen margins were negative for any micro-invasions. Sonographically, all lymph nodes were oval in shape and were preserving the sinus fat. The largest lymph node revealed a reactive enlargement, yet subcentimeteric (0.08 × 0.04 in the largest dimensions). Immunohitsochemically, the tumoral cells were strongly positive both for Calretinin and for Wt-1 but were negative for Ber-EP4. Therefore, the lesion was signed out as a benign adenoid variant of peripheral ameloblastoma.
