简要总结
This study will be conducted to evaluate influence of Facial height, facial width, interpupillary and intercommisural width over the size of buccal corridor on smiling in periodontally healthy males and females.
Total of 200 subjects with age range of 20-40 years including both male and female visiting the Department of Periodontics at VSPM Dental College and Research Centre, Nagpur will be recruited.
Study population will be divided into 2 groups:
Group I – 100 periodontally healthy males in the age range of 20-40 years.
Group II – 100 periodontally healthy females in the age range of 20-40 years.
A written informed consent will be taken from the patients who wish to enroll in the study. The study parameters of the patients will be assessed clinically and on digital photographs. Frontal view photographs of the subjects will be taken while smiling.
Determination of anterior Facial Height (FH):
For the measurement Total facial height (Tr-Me), the distance between Trichion (Tr)—the front line of the hair in the midline and menton (Me)—the lowest soft tissue point of the mandible , will be measured using a digital vernier caliper.
Determination of Facial width (FW):
Facial width will be measured as the bizygomatic width (the distance between the most prominent points on bilateral zygomatic arches)with the help of digital vernier caliper.
Determination of Interpupillary Width(IPW) in mm:
For the measurement of IPW, the midpoint of the pupils will be marked on a wooden tongue spatula which will be measured with a digital vernier caliper.
Determination of Inter-Commisural Width(ICOW) in mm:
The ICOW will be determined by measuring the maxillary lip vermilion from left commissure to right commissure with a digital vernier caliper.
Width of Buccal Corridor at smile: The right and the left buccal corridor spaces will be determined as the distance between the most buccal surface of the visible, posterior most maxillary tooth on either side and the right and the left commisures respectively.
