Independent predictors of satisfaction in impacted third molar surgery patients

Effectiveness of anesthetic solutions for pain control in lower third molar extraction surgeries: a systematic review of randomized clinical trials with network meta-analysis

OBJECTIVE

To assess the effectiveness of different anesthetic solutions for pain control immediately after the extraction of lower third molars.

METHODS

Nine databases were used to identify randomized clinical trials, without restriction of language or year of publication. The "JBI Critical Appraisal Tools for Systematic Reviews" was used to assess the risk of bias in the studies. The network meta-analysis was performed to compare the effectiveness of different anesthetics to control the pain immediately after the surgery of lower third molars, using the standardized mean difference (SMD) as the effect estimate. The GRADE approach was used to assess the certainty of evidence.

RESULTS

The search presented 13,739 initial results, from which 45 met the eligibility criteria and presented low to moderate risk of bias. Thirteen studies were included in the meta-analysis. The 2% lidocaine + clonidine presented the lowest pain scores (SMD = - 1.44; - 2.72 to - 0.16) compared to 4% articaine + adrenaline, followed by 0.5% bupivacaine + adrenaline (SMD = - 1.36; - 2.13 to - 0.59). The certainty of evidence varied between very low to moderate.

CONCLUSION

2% lidocaine + clonidine and 0.5% bupivacaine + adrenaline were the anesthetics with the highest probability for pain control immediately after the surgical procedure of removing impacted lower third molars.

CLINICAL SIGNIFICANCE

The use of an adequate anesthetic with effective pain control can contribute to a more comfortable postoperative period.

Dental School Patient Preferences for Receiving and Returning Patient Satisfaction Surveys

The aims of this study were to investigate dental school patient, parent, and caregiver preferences for receiving and returning patient satisfaction surveys and to determine how modes of receiving and returning surveys impacted return rates. Two studies were conducted, both of which are reported. In Study 1, adult patients, parents of child patients, and caregivers of patients with special needs were asked to indicate their preferred mode of receiving and returning surveys. In Study 2, patients, parents, and caregivers were randomly assigned to different modes of receiving and returning surveys, and return rates were compared between modes and according to whether the individuals had been assigned to their preferred mode or not. The overall response rates were 90.4% for the first study and 48.1% for the second study. In both studies, the preferred mode was receiving and returning the survey in the clinic (chi-square=84.902 and 32.116; df=3; p<0.001). Younger respondents were more likely to prefer receiving and returning the survey by email (K-W statistics=13.406, 10.241; df=3; p=0.004 and 0.017). In Study 2, respondents were significantly more likely to return surveys in the clinic (chi-square=44.994; df=2; p<0.001) and were also significantly more likely to return surveys if they had received them in their preferred mode (binomial test p<0.001). Although receiving and returning the survey in the clinic was the preferred mode, these respondents' preferences were also related to their age. These results suggest that dental school clinics may be able to expect higher return rates if they can follow patients' preferences for receipt and delivery of surveys.

Scales used to rate adult patients' psycho-emotional status in tooth extraction procedures: a systematic review

The aim of this study was to review scales used to assess anxiety, stress, and pain in dental patients undergoing a tooth extraction procedure and to propose a novel psycho-emotional rating scale based on the relevant literature and our own experience. An electronic literature search was conducted of the National Library of Medicine database MEDLINE (Ovid) and EMBASE databases between January 2005 and April 2016. Sequential screening at the title/abstract and full-text levels was performed. The review included all human prospective or retrospective follow-up studies and clinical trials, cohort studies, case-control studies, and case series that demonstrated at least one scale used to measure tooth extraction anxiety, stress, or pain. The search resulted in 32 articles meeting the inclusion criteria. None of the studies were found to be suitable in evaluating patient's stress, pain, and fear at once. Also, no scales were found that included both the doctor's and the patient's rating. In a few studies, vital signs as psycho-emotional status indicators were rated. Guidelines for a suitable questionnaire that could be used for rating the psycho-emotional status of patients undergoing tooth extraction are listed in the present research. Further studies are required for verification and validation of offered scale.

Non surgical predicting factors for patient satisfaction after third molar surgery

Background

In the third molar surgery, it is important to focus not only on surgical skills, but also on patient satisfaction. Classically studies have been focused on surgery and surgeon’s empathy, but there are non-surgical factors that may influence patient satisfaction.

Material and Methods

A cross-sectional study was performed on 100 patients undergoing surgical extractions of impacted mandibular third molars treated from October 2013 to July 2014 in the Oral Surgery Unit of the University of Valencia. A questionnaire (20 questions) with a 10-point Likert scale was provided. The questionnaire assessed the ease to find the center, the ease to get oriented within the center, the burocratic procedures, the time from the first visit to the date of surgical intervention, waiting time in the waiting room, the comfort at the waiting room, the administrative staff (kindness and efficiency to solve formalities), medical staff (kindness, efficiency, reliability, dedication), personal data care, clarity in the information received (about the surgery, postoperative care and resolution of the doubts), available means and state of facilities. Outcome variables were overall satisfaction, and recommendation of the center. Statistical analysis was made using the multiple linear regression analysis.

Results

Significant correlations were found between all variables and overall satisfaction. The multiple regression model showed that the efficiency of the surgeon and the clarity of the information were statistically significant to overall satisfaction and recommendation of the center. The kindness of the administrative staff, available means, the state of facilities and the comfort at the waiting room were statistically significant to the recommendation of the center.

Conclusions

Patient satisfaction directly depends on the efficiency of the surgeon and clarity of the clinical information received about the procedure. Appreciation of these predictive factors may help clinicians to provide optimal care for impacted third molar surgery patients.

Compliance of postoperative instructions following the surgical extraction of impacted lower third molars: a randomized clinical trial

Objectives: The understanding and adherence to postoperative care instructions are factors that influence the recuperation process after any surgical procedure. The aim of this study was to determine the percentage of patients who strictly follow the postoperative instructions after the extraction of an impacted lower third molar in relation to sociocultural level, preoperative anxiety scores and how postoperative information is provided to the patient. Study Design: Patients were randomly assigned to one of three different test groups according to how the postoperative instructions were presented: verbal, written and a group that received additional information. Before surgery, patients were required to complete the Corah Dental Anxiety Scale and personal information (age, gender and educational level) was also collected. P<0.05 was considered significant. Patients were surveyed a week after surgery regarding their adherence to postoperative instructions. Results: 84 patients (45 women and 39 men with an average of 28.23 ± 7.41 years) completed the study. There were no statistically significant differences regarding adherence of postoperative care instructions depending on the manner of instruction presentation, preoperative anxiety level and sociocultural level (p> 0.05). Quitting smoking or drinking of alcoholic/carbonated beverages were the main influential factors for the lack of adherence to postoperative care instructions during the week after surgery. Conclusions: Presentation of postoperative instructions, preoperative anxiety scores and sociocultural level do not appear to be key factors that promote the adherence to postoperative instructions.
