Introduction
The formation of palatal rugae is completed in the early intrauterine stage, and because of their unique and permanent pattern in each individual, they can be utilized in forensics to identify a person.
Objective
The primary objective of this study was to determine an association between the rugae pattern and the dental malocclusion system described by Angle.
Materials and methods
A prospective cross-sectional, observational study was conducted on pretreatment dental casts of 400 subjects in an age range of 18-40 years. The samples were divided according to Angle’s system of classification of malocclusion into Class I, Class II, and Class III. The number, length, pattern, and orientation of the three anterior-most primary rugae on both sides of the palatal region were studied.
Results
Significant differences were noted in the mean number of palatal rugae and mean lengths of rugae 1 and 2 on the right side (p < 0.001) and rugae 3 on the left (p < 0.001) side among the different malocclusion groups. Curved and wavy patterns were predominant, and significant differences were found among the groups (p < 0.05), whereas non-significant differences were observed in the rugae orientation between the groups on the right and left sides.
Conclusions
The current study showed significant differences in the length, number, and pattern of the palatal rugae among Angle's classes of malocclusion.
Clinical implications
Palatal rugae can be effectively used to identify dental malocclusion at an early stage and can, therefore, help intercept the developing malocclusion.
Aim:
Managing postoperative pain following maxillofacial surgery is an important task. Our study aims to compare this with regional anesthesia or IM diclofenac.
Materials and Methods:
This study included 30 patients who underwent bi-jaw orthognathic surgery between April 2016 and January 2020. Two groups were formed. Group A was administered inferior alveolar nerve block at the surgical site bilaterally using 0.5% ropivacaine and Group B were administered 75 mg intramuscular diclofenac just before extubation. Tramadol HCl 2 mg/kg body wt is used as a rescue analgesic. The pain was evaluated periodically at 2

, and 12 h postoperatively.
Results:
The mean Visual Analog Scale score was 2 in Group A and 5 in Group B. The mean duration of analgesia was 6 h 42 min, whereas in Group B, it was 8 h and 5 min. In 2 patients (13.3%) belonging to Group A and 3 patients (20%) belonging to Group B. There were no local complications in any group.
Conclusion:
It was observed that regional anesthesia in the form of intraoral nerve blocks was efficient than diclofenac (75 mg) administered intramuscularly for the management of immediate postoperative pain.
