Abstract Objective: To test the hypothesis that the amount of buccal corridor has no influence on smile evaluations of Japanese orthodontists and dental students. Materials and Methods: One photograph of a smiling female, displaying first molar to first molar, was constructed. Buccal corridors were modified digitally in 5% increments, from 0% to 25% buccal corridor compared with the inner commissural width. Using a visual analog scale (VAS), 32 Japanese orthodontists and 55 Japanese dental students rated the attractiveness of six smiles with altered buccal corridors. The Wilcoxon rank-sum test was conducted to compare the distributions of the median scores between the male and female raters for each of the rater groups. Differences in the median esthetic scores were analyzed using the Kruskal-Wallis test. We used 15% VAS difference to determine the clinical significance of the esthetic scores. Results: There was no significant difference in judging the effects of buccal corridors on the smile attractiveness between the male and female raters for both the orthodontists and dental students. There were significant differences in the median esthetic scores for both the orthodontists and dental students. The median esthetic score decreased to become clinically significant from 10% to 25% buccal corridor for both the orthodontists and dental students. Conclusions: The hypothesis was rejected. Both the orthodontists and dental students preferred broader smiles to medium or narrow smiles.

Aims of the Study: The aims of the study are: (a) to compare the perceptions of dental specialists and laypeople regarding smile esthetics; (b) to compare male and female smile parameters; (c) to find influence of smile parameters on esthetics of smile. Materials and Methods: The study was conducted on 60 subjects (30 males and 30 females) of age 18 to 25 years. Frontal posed photographs of all subjects were taken using a digital camera and rated on a visual analog scale by 10 dental specialists and 10 laypersons. Measurements made on photographs were used to analyze various parameters of smile, such as buccal corridor space, smile arc, modified smile index, anterior height of smile, most posterior maxillary tooth visible, and midline relationship of central incisors to philtrum. Results: Visual analog scale values showed that 6 photographs were rated as very good (3 males, 3 females), 29 as good (11 males, 18 females), 21 as average (13 males, 8 females), and 4 photographs were rated as bad (3 males, 1 female). A high correlation was observed between ratings of dental specialists and layperson’s ratings for both male and female smiles. Most of the subjects had non-consonant smile arc, and a high correlation was found between buccal corridor space on right and left sides in both males and females. Most of the male and female smiles had an average anterior height of smile; permanent maxillary first molar was the last tooth visible during smile (73.3% females, 66.7 males); and 55% subjects had coincident midline relationship of central incisors to philtrum. Conclusion: There was no significant difference in perception of dental specialists and laypersons regarding esthetics of smile. Smile arc and anterior height of smile influenced the esthetics of smile. No significant difference was found between male and female smile parameters except modified smile index.

OBJECTIVE: To assess the influence of buccal corridor width on smile esthetics of male and female, Caucasian and Afro-descendant subjects by means of digitally manipulated photographs, as well as compare assessments of full-face view (FFV) and close-up view of the mouth (CUVM) images. METHODS: Facial photographs were taken of four adults' smile, two Caucasians and two Afro-descendants of both genders. The resulting images were digitally manipulated with the aim of rendering - from each original smile - three other smiles simulating three different buccal corridor widths, namely, narrow, medium width and wide. The rendered images, 12 of which portraying FFVs and 12 providing CUVMs, were assessed by 60 examiners who rated the attractiveness of each smile by means of a visual analog scale (VAS). The data were treated with ANOVA and Tukey's post test to compare the different buccal corridors, and Student's t test to compare the two image views (FFV and CUVM). RESULTS: Medium width buccal corridors were considered the most attractive in the four individuals investigated, both in the assessment of FFVs and CUVMs (p < 0.05). Comparison between the narrow and wide buccal corridors, in general, showed no statistically significant differences (p > 0.05). Furthermore, no statistically significant difference was found between the analyses of FFVs and CUVMs (p > 0.05). CONCLUSION: The buccal corridor exercised a remarkable influence on smile esthetics, with the medium width group being rated as the most attractive. No influence was exerted by the individuals' face, ethnicity or gender.

Summary Background/Aim: The aim of this study was to investigate in the esthetic perceptions of 2nd grade dental students before and after training. Material and Methods: A total of 16 photographs which contain golden ratio, buccal corridor, midline deviation, incisal embrasure, lip line, midline diastema, dark triangles and smile arc were shown to 78 dental students (33 male, 45 female). Immediately after the training about the smile esthetics, the same photos were shown again. The effect of gender on esthetic perception was also examined, in addition to assessing the effects of education on esthetic perception. Pearson Chi-square, Fisher’s Exact test and McNemar test were used in the analysis of the results. Results: According to the results of the analysis, it was found that the answers of the smile arc before and after the education were statistically significant (p< 0.05). Accordingly, the rate of correct answers of women is statistically higher than that of men. A statistically significant difference was found between the responses to the gingival appearance in the smile before and after the education (p< 0.05). Conclusions: Based on the limited results of this study, professional dental education may affect the esthetic evaluation of smile. There were differences in the esthetic perception of women and men.

Background: Post tonsillectomy pain is one of the surgery side effects that most disturbing for patient’s comfort and will cause dysphagia, low intake, dehydration, secondary infection and bleeding. Ketamine is an anesthetic drug that has strong analgesic effect and easily available in any hospital at relatively cheap price. Objective: To find out the effect of local ketamine infiltration on the post tonsillectomy pain scale. Method: An experimental study during tonsillectomy with a Post Test Control Group on 12 samples without local infiltration of ketamine and 12 samples with local infiltration of ketamine in peritonsillar pillar. The pain was assessed 2 hours and 24 hours post extubation with pain Visual Analog Scale (VAS). Result: The VAS value from patients who were given local infiltration of ketamine in peritonsillar pillar were lower (5.83 ± 0.72 at 2 hours and 2.83 ± 0.58 at 24 hours post extubation) compared to patients without ketamine infiltration (7.83 ± 0.58 at 2 hours and 3.58 ± 0.51 at 24 hours post extubation). The result showed statistically significant difference (p <0.05) at 2 hours and 24 hours post extubation. Conclusion: The VAS score of the ketamine infiltration group is lower at 2 hours and 24 hours post extubation than the group without ketamine infiltration, showing there was a noticeable effect of local ketamine infiltration on the post tonsillectomy pain scale.Keywords : post tonsillectomy pain, ketamine, local infiltration, visual analog scale ABSTRAKLatar belakang: Nyeri pascatonsilektomi adalah salah satu efek samping operasi yang sangat mengganggu kenyamanan pasien, dan dapat menyebabkan gangguan menelan, kurangnya asupan nutrisi, dehidrasi, infeksi sekunder dan perdarahan.

BackgroundPain is a subjective sensation; self-reporting is important for quantifying pain intensity. There are several different validated tools for this, such as Visual Analog Scale and Numeric Rating Scale. In the clinic, these terms are often used as equivalent. The objective of this study was to examine correlation and agreement between the pain registration tools in triage in an emergency department.Materials and MethodsThe study was performed in the Department of Emergency Medicine at Haukeland University Hospital in the period June-August 2019. We registered the pain score with two tools in 200 unselected patients in emergency admission with pain. In addition, we registrered gender, age, triage and general department affiliation.ResultsWe found a strong correlation between the pain registration tools by Spearmans correlation test (rho=0,930, p<0,001). There were no significant difference between the pain registration tools within the subgroups. Bland-Altman analysis show agreement between the two pain registration tools.ConclusionsIn an Emergency Department triage is it acceptable to use Visual Analog Scale and Numeric Rating Scale as equivalent, as long as the correct terminology is used.

Context: Plantar fasciitis (PF) is a common and devastating disease. Despite different treatments, there is no clear evidence for the effect of these treatments on PF. One of the therapy methods used in physiotherapy is dry needling (DN). So the purpose of this study is to investigate the effect of DN on the pain and range of motion of the ankle joint and plantar fascia thickness in subjects with PF who are suffering from the trigger points of the gastrocnemius and soleus muscles. Methods: In this study, 20 volunteer females with PF were randomly assigned into DN treatment and control groups. Measurements were range of motion in dorsiflexion and plantar flexion, plantar fascia thickness, and visual analog scale measured before, immediately, and 1 month after the end of the intervention in both groups. Results: There were significant differences in the plantar fascia thickness and visual analog scale between the 2 groups. Plantar fascia thickness (P = .016) and visual analog scale (P = .03) significantly decreased in the treatment group. However, there was no significant difference in plantar flexion (P = .582) and dorsiflexion range of motion (P = .173) between groups. Conclusion: The result of this study showed that DN can reduce pain and plantar fascia thickness in women with PF who are suffering from trigger points of the gastrocnemius and soleus muscles. Level of evidence: Level 1, randomized controlled trial.

Objectives: Patient satisfaction is being increasingly reported in orthopaedic sports medicine and the field of hip preservation surgery. The Visual Analog Scale (VAS) for Satisfaction is most commonly utilized. Currently there is limited understanding for what should be considered as clinically important improvement on the VAS Satisfaction. The purpose of this study is to 1) define Substantial Clinical Benefit (SCB), Patient Acceptable Symptomatic State (PASS), and Minimal Clinically Important Difference (MCID) for the VAS Satisfaction in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS), and 2) identify preoperative predictors of achieving each outcome end-point. Methods: Data from consecutive patients who underwent primary hip arthroscopy between November 2014 and January 2017 were collected and analyzed. Baseline data and postoperative patient-reported outcome (PRO) scores were recorded at 2-years postoperatively. In order to quantify clinical significance of outcome achievement on the VAS Satisfaction we calculated MCID, PASS and SCB for this outcome measure. A multivariate logistic regression analysis was used to identify preoperative predictors of achieving SCB, PASS, and MCID satisfaction. Results: A total of 335 patients were included in the final analysis, with an average age and body mass index (BMI) of 32.8(SD+12.4) years and 25.2(SD+5.3) respectively. The values on the VAS satisfaction were identified to represent MCID, PASS and SCB respectively: 12.3, 80.9 and 89.7. The rates of achieving clinically significant improvement on the VAS Satisfaction was 97.1%, 68.1% and 56.9% for MCID, PASS and SCB respectively. A larger preoperative alpha angle was predictive for achieving SCB (OR:1.076; p =0.046), while lower BMI (OR:0.955; p =0.047) and larger preoperative alpha angle (OR:1.12; p-value=0.025) were predictors for achieving PASS. Conclusions: This study identifies scores on the VAS Satisfaction that can be used to define clinically significant outcome after arthroscopic treatment of FAIS. Specifically, an improvement of 12.3 points is a clinically important improvement in satisfaction, while an absolute score above 89.7 represents the upper threshold of Satisfaction performance. Almost all patients (97.1%) demonstrated a clinically important improvement in satisfaction. Additionally, there are both modifiable and non-modifiable factors that predict achieving a clinically significant level of post-operative satisfaction on the VAS Satisfaction.

Background: Government of Nepal has been conducting Cesarean section under “Safe Motherhood” program all over country. The purpose of this study was to evaluate the efficacy and safety of intrathecal morphine for post cesarean analgesia under spinal anesthesia.  Methods: A total of 300 parturients posted for Cesarean section under spinal anesthesia were divided into two groups of 150 each in this prospective randomized case-control study. Morphine group received 0.15 mg of intrathecal morphine mixed in 12 mg of 0.5% bupivacaine heavy while control group received 12 mg of 0.5% bupivacaine heavy alone, after proper preparation of spinal anesthesia. The parturients were assessed for first request of analgesic as per Visual Analog Scale, frequency of analgesics required within 24 hr, nausea, vomiting, pruritus, sedation and respiratory depression.Results: Postoperative analgesia was significantly greater in morphine group as compare to control group (12.1 ± 7.6 vs 3.7 ± 2.9 hr). Frequency of analgesics requirements was also significantly lower in morphine group (1.7 ± 2.0 vs 3.4 ± 8.1). Visual Analog Scale was below 4 at most of time in morphine group. The incidence of nausea, vomiting and pruritus were more in morphine group as compare to control group but without any respiratory depression. There was no significant difference in APGAR score among fetus.  Conclusion: Mixing low dose of intrathecal morphine in standard dose of spinal anesthesia effectively prolongs the duration of post cesarean analgesia and decreases the frequency of analgesics requirement without any major complication in parturients or fetus.Journal of Society of Anesthesiologists 2014 1(1): 13-17
