简要总结
This study will be conducted to evaluate and correlate facial height, dimensions of anterior teeth, with the shape of a crown with facial esthetics in periodontally healthy males & females.
A total of 200 subjects with an age range of 20-40 years including both males and females visiting the Department of Periodontics at VSPM Dental College and research center Nagpur will be recruited. Study participants will be divided into 2 groups Group I – Will comprise of periodontally and systemically healthy 100 males within an age range of 20-40 years.
Group II – Will comprise of periodontally and systemically healthy 100 females within an age range of 20-40 years.
A brief description of the entire procedure will be given to every patient before starting the procedure. For all subjects following periodontal parameters will be recorded:
1. Plaque index (Silness and Loe 1964)
2. Gingival index (Loe and Silness 1963)
The study parameters of the patients will be assessed clinically and on digital photographs. Frontal view photographs of the subjects that will be fixed in the Frankfort horizontal plane. For the measurement of total facial height (Tr-Me): naso-menton length, These landmarks will be trichion (Tr)—the front line of the hair in the midline and menton (Me)—the lowest soft tissue point of the mandible will be the two-point used to determine the anterior facial height that will be measured with a digital vernier caliper. Crown width will be measured at the junction between the cervical and middle section of the crown. The crown height will be assessed by measuring the distance between the most apical portion of the facial gingival margin and the incisal edge of the crown, parallel to the long axis of the tooth using digital photographs. To determine contact surface height the length of the contact surface will be measured from the most apical portion of the contact area to the most incisal portion on the mesial surface of the central incisor using digital photographs. The value of crown width and length of maxillary anterior teeth will be determined by dividing the values. the shape of crowns in the maxillary anterior region of the jaw will be determined it can be triangular crown shape, tapered squarish crown shape, squarish crown shape.
And then correlation among facial height, height, and width of maxillary anterior teeth, contact surface height, crown width to length ratio, and shape of a crown in periodontally healthy males & females will be done.
