ABSTRACT
Aim: Determination of the plane of occlusion in completely edentulous patients with the help of the ala‑tragus line (Camper’s plane) may be questioned. An attempt to devise an alternative method to determine the orientation of the plane of occlusion was made. Materials and Methods: Cephalometric analysis was used to identify whether a correlation exists between the plane of occlusion of dentulous Indian individuals and other stable cranial landmarks. Results: A negative correlation was found to exist between the occlusal Plane–FH plane angle and the porion–nasion–anterior nasal spine (PoNANS) angle. Conclusions: From the derived mathematical correlation, it was concluded that the angulation of the occlusal plane in completely edentulous subjects may be determined by taking a cephalogram at the diagnostic stage. Further, the clinical applicability of the derived mathematical formula (while determining the plane of occlusion) was tested on completely edentulous patients.
ABSTRACT
Purpose: The purpose of this study was to find the correlation between vertical dimension of occlusion (VDO) and length of fingers. Materials and Methods: A cross-sectional study was conducted on 400 dentate subjects comprising of 200 males and 200 females. Anthropometric measurements of VDO, length of index finger, length of little finger, and distance from tip of thumb to tip of index finger of right hand were recorded clinically using modified digital vernier caliper. Correlation between VDO and length of fingers was studied using Spearman's coefficient. For the execution of regression command and preparation of prediction equations to estimate VDO, Statistical Package for Social Sciences Software Version 11.5 was used. Results: VDO was significantly and positively correlated with all the parameters studied. In males, correlation of VDO was strongest for length of index finger (r-0.406) whereas in females, it was strongest for length of little finger (r-0.385). VDO estimation using regression equation had a standard error of ± 3.76 in males and ± 2.86 in females for length of index finger, ±3.81 and ± 2.74 in males and females respectively for length of little finger, ±3.99 and ± 2.89 in males and females respectively for distance from tip of thumb to tip of index finger. Conclusions: Since the variations between VDO and finger lengths are within the range of 2-4 mm, VDO prediction through this method is reliable, and reproducible. Also the method is simple, economic, and non-invasive; hence, it could be recommended for everyday practice.
ABSTRACT
Background : Office hysteroscopy with endometrial biopsy is usually the first investigation for abnormal uterine bleeding and other uterine diseases. Aims: To evaluate the effect of oral drotaverine with mefenamic acid on pain perception during hysteroscopy and endometrial biopsy and to compare it with that of paracervical block using 1% lignocaine and with that of intravenous sedation using diazepam with pentazocine. Settings and Design : Outpatient gynecological department and open randomized trial. Materials and Methods : One hundred twenty women undergoing hysteroscopy and endometrial biopsy were randomized into 3 groups. Group I received tablet containing drotaverine hydrochloride (80 mg) + mefenamic acid (250 mg), group II received lignocaine paracervically and group III received intravenous diazepam. The intensity of pain during the procedure, 30 and 60 minutes later on visual analog scale (VAS) was assessed. Statistical Analysis : Statistical analysis was performed using Kruskal-Wallis test, with the Bonferroni correction, the t test, and the χ2 test. Results: Groups were similar in age, parity, vaginal birth or relevant medical history. A statistically significant difference in pain scores was noted among the 3 groups during the procedure (group I, 4.13± 1.28; group II, 5.93± 1.26; group III, 5.58± 1.51), (P< 0.001); as well as 30 minutes later (group I, 1.78± 0.89; group II, 2.53± 0.81; group III, 2.23± 0.94), (P< 0.001) and 60 minutes later (group I, 1.2± 0.46; group II, 1.98± 0.83; group III, 1.68± 0.75), (P< 0.001). VAS at different time intervals among the groups was also statistically significant. No adverse effects were observed. Conclusions : Oral drotaverine with mefenamic acid is effective in women undergoing hysteroscopy and endometrial biopsy.
