research _ treatment of maxillary radicular cysts I mainandControl1groups,0.12%chlorhexidinewas prescribed(risingthreetimesperday)forthreeweeks post-operatively for oral hygiene. The treatment of theControl2and3groupswasprovidedinotherclin- ics, and the data collection and details regarding the treatment process were obtained from the archives oftherespectivecityclinics.Theanamnesisandpost- operative description of the soft-tissue condition were done at the Dental Training Centre (DSPMC) at P.L. Shupyk National Medical Academy of Postgrad- uate Education in Kiev. _Results Ourpreliminaryresultsduringobservationshowed that the healing process in the main group was not accompanied by pain, owing to wound stability due to the suturing technique used. Only 33% of pa- tients in the main group experienced pain on Day 1 and 2 post-operatively, compared with 50–60% of patientsinallthreecontrolgroupswhoexperienced painfor1–7days.Alsopost-operativefacialoedema wasobservedinallpatients,butitsdurationwasthe shortest in all three patients in the main group, last- ing1–2days,withasignificantdecreaseonthethird day. In patients in all three control groups, general antibiotic therapy was prescribed; in spite of this, in 25–50% of patients, a slight temperature increase was observed (from 37.0°C to 37.5°C) 1–2 days post-operatively. In the main group, general an- tibiotic therapy was not prescribed and the tem- perature increase was absent in all patients. Pa- tientsinallthreecontrolgroupsreportedslightdis- comfort during eating 1–7 days post-operatively, but this was completely absent in patients in the main group. During examination of post-operative ossifica- tion, the preliminary observation three weeks post- operatively was a decrease in the cystic cavity bone defect due to peripheral defect ossification corre- sponding to physiological mechanisms. Post-oper- ative recession occurred in 40% of patients in the Control 1 group and in 87.5 % of patients in the Control 2 and 3 groups after one month. The rate was20%and87.5%,respectively,aftertwomonths and20%and75%,respectively,afterthreemonths. Inpatientsinthemaingroup,marginalcontoursta- bility was observed and absence of recession after three months post-operatively. Fig. 16_A panoramic radiograph six months post-op. In the area of the defect, new bone formation can be observed. The apical filling with ProRoot MTA can be seen in teeth #11 and 12, and no signs of inflammation can be seen in the surgical area. Fig. 17_A radiograph of teeth #11–13, showing new bone formation and a reduction of the defect contour. Figs. 18a–c_A CT scan of tooth #11 six months post-op in the area of the previous defect (a). The bone density is 135.685 HU (b). In comparison, the cortical bone density in the area of tooth #21 is 716 HU (c). Table 4_Details of post-operative clinical manifestations.
