The present study was undertaken to assess the skeletal craniofacial asymmetry in South Indian population by a posteroanterior cephalometric radiographic method. The skeletal craniofacial structures on one side of the face were compared with that of the other, by drawing various triangles representing different craniofacial regions.
The sample consisted of 60 subjects (30 males and 30 females) aged between 18 to 25 years, who were mainly dental college students from South India. Overall 52 X-rays were obtained, with four errors each in the male and the female groups.
The results revealed that the total facial structures in the South Indian population were larger on the left side (statistically insignificant). The cranial base area exhibited a greater degree of asymmetry than any other component area of the face, which might be due to the inaccuracy at the condylar point.

Aim:The aims of this study were to evaluate the dental changes brought about by activator and activator headgear combination (ACHG) and to determine whether we can achieve control over the lower incisor proclination which is a side effect of using functional appliances; or not, while treating cases of skeletal class II malocclusions.Methods: Lateral cephalograms of 45 skeletal class II division 1 patients were selected for the study. Fifteen of them were successfully treated with an Andresen activator and the other 15 with an activator headgear combination. Fifteen class II subjects who had declined treatment served as the control group. Cephalometric landmarks were marked by one author to avoid interobserver variability.
Results:The results revealed that both the activator and the activator headgear combination significantly (p < 0.001) affected dental variables measured. The mandibular incisor proclination was effectively controlled in the activator headgear combination group.
Conclusion:An activator headgear combination would offer itself as a better option compared with activator alone in the treatment of skeletal class II malocclusions especially in cases with proclined mandibular incisors.Clinical significance: When one of the treatment goals is to achieve a greater control over mandibular incisor proclination in the treatment of Skeletal Class II malocclusions, employing a combination of activator and headgear may substantially improve clinical outcomes.
In forensic, odontologic, genetic, and anthropological aspects, odontometric and osteologic features have long been a valuable source. The goal of this research was to correlate both the osteologic and odontometric characteristics to determine the most accurate approach for determining gender. A retrospective study involving 1000 adults, with equal gender distribution, was carried out utilizing digital panoramic radiography. The archives were searched for radiographic images of the subjects that were procured for the various procedures that ranged from implantations to rehabilitations. The measurement process was carried out with Image-Pro. There was a noticeable gender difference in the mesodistal breadth, which ranged from 17 to 47. Asymmetry of the lower jaw was considerable in both genders, as was gender variance in osseologic characteristics including ramus diameter and gonial angle. The two groups of attributes exhibited a substantial positive predictive value and thus can be used indetermining gender.
