“…This study was conducted from July 2020 to February This study recorded low SBP (SBP1) in the waiting room. It contrasted with some studies where the highest SBP values were taken in the waiting room [15][16][17]. The low SBP1 values throughout the surgical extraction, with a statistically significant difference of (p < 0.001) (Table 5).…”

Objective: This study assesses the changes in the haemodynamic parameters of normotensive patients that underwent surgical extraction of impacted mandibular third molars following the administration of Lidocaine Hydrochloride (HCl) 2% with Adrenaline 1:80,000. Materials and methods:This prospective cohort study was conducted on 168 patients who presented at the outpatient clinic with the indication(s) for surgical extraction. Patients aged 18 years and above, whose SBP was between 90 mmHg -120 mmHg and whose DBP was between 60 mmHg -80 mmHg, were included in the study. The patients' HP was taken at four different time points, namely T1, T2, T3, and T4, using a pre-calibrated non-invasive electronic BP machine (ANDON BPM) and Pulse oximeter (CA-MI).Statistical analysis was done using the Statistical Package for Social Sciences (IBM) 25.0 version. The significant level was set at a p-value of < 0.05 at a 95% confidence interval.Results: All the SBP and DBP readings showed a gradual increase in values from SBP1 and DBP1 to SBP4 and DBP4, respectively, with a statistically significant difference (p < 0.001). The highest elevation was recorded between SBP1 and SBP4 at 12.2 mmHg change as well as between DBP1 and DBP4 at 11 mmHg change. There was an increase in the values of HR throughout the surgery, showing a statistically significant difference (P < 0.001). There was a decrease in the SPO2 values throughout the surgical extraction, with a statistically significant difference of (p < 0.001). Conclusion:This study revealed an increase in systolic blood pressure, diastolic blood pressure and heart rate but a decrease in the oxygen saturation level of the patients. There was a statistically significant change in the haemodynamic parameters across all four points studied.

“…Most of the studies used the operative time (measured from the incision to the last suture) as a post-operative variable indicating the degree of difficulty ( 17 , 18 - 21 , 24 - 28 ). Others used scales that evaluate the type of surgical technique ( 16 , 18 , 20 , 24 , 25 ) and only 1 registered a score reported by the surgeon after the surgery to subjectively classify difficulty ( 23 ). Few studies reported on the experience of the surgeon(s) operating the cases included in the studies.…”

“…All studies showed an improvement on the prediction of the surgical difficulty when using the new indices/scales or the proposed modifications of the pre-existing ones in comparison with pre-existing indices. Only 1 study failed to demonstrate improvement of a new index with respect to the modified Parant scale ( 24 ).…”

Background The main objective of this systematic review was to collect the pre-existing scales for assessing the difficulty of third molar extraction. The secondary objective was to design a proposal for a preoperative evaluation protocol for the difficulty of third molar extraction. Material and Methods Two independent researchers conducted an electronic search in Pubmed (MEDLINE), Cochrane, and Scopus databases during March 2021. Included studies evaluated the prediction of the difficulty of surgical removal of impacted upper or lower third molars using new indices/scales or pre-existing scales with or without modifications. Articles referring to coronectomies or assessing pre-surgical difficulty using other tools were excluded. Neither language nor publication date restrictions were applied. Results Out of 242 articles, 13 prospective cohort studies were finally selected. Seven developed new indices/scales, and 6 assessed the predictive ability of some pre-existing scales. Most of the indices/scales contained radiological variables and few added any patient-related variables. We proposed a preoperative assessment protocol of the difficulty of third molar extraction to facilitate treatment planning and/or considerate referral in cases of high difficulty. This proposal used patient-related, radiological and surgical variables. Conclusions Using a preoperative protocol to evaluate the surgical difficulty, including different patient-specific, radiological and surgical variables, could facilitate treatment planning, help clinicians prevent complications and assess the possibility of referral. Key words: Wisdom teeth, patient characteristics, radiological variables, surgeon experience, assessment form.

“…Although indices based on clinical and radiographic parameters are comprehensive, they tend to be time-consuming. Most radiography-based indices being used currently in dentistry are based on conventional radiographic techniques [19][20][21]. The index used in the present study evaluated surgical difficulty on the basis of CBCT findings.…”

Objectives. Radiography-based indices can help surgeons perform detailed examinations of the surgical site and predict the surgical difficulty of cases. We aimed to develop and validate a novel CBCT-based index that can predict the surgical difficulty of sinus-augmentation procedures. Materials and Methods. In the first stage, five experienced dental specialists performed a review of the literature and closed group discussions and designed the novel index. In the next stage, the index was validated. CBCT scans of 30 patients scheduled for sinus-augmentation procedures were evaluated and assigned presurgical CBCT evaluation scores (PSCESs) by five examiners. Subsequently, one oral surgeon performed sinus augmentation using the lateral antrostomy technique and assigned surgical difficulty scores (SDSs) to each of the 30 cases along with 2 observers. The PSCESs and SDSs were statistically analysed to determine the interrater reliability and validity of the index. Results. The interrater agreement of the PSCES among the five presurgical evaluators was 0.85. The PSCES of the five evaluators had highly significant correlation ( P < 0.001 , r = 0.68 to 0.76 ) with the SDS. Regression analysis revealed that for every unit increase in the PSCES, there is 0.46 to 0.57 increase in the SDS value. Conclusion. The results of this pilot study revealed that a novel CBCT-based index can be used as a reliable tool for predicting the surgical difficulty of sinus-augmentation procedures. However, the novel index needs to be tested on a larger sample of patients and evaluators for a more concrete validity and reliability.
