RESUMEN

Emergence of soft tissue paradigm in clinical orthodontics has made smile analysis and designing key elements in treatment planning. Smile is an integral constituent of the facial attractiveness of a person. Various factors influence smile. The smile frame work is influenced by gingival display during smiling, incisors display and the buccal corridor space. Buccal corridor area show according to many influences smile immensely. Lateral cephalograms were taken with patient's Frankfort Horizontal plane parallel to the floor, unstrained lips and teeth in centric occlusion. Radiographs were traced. Ratio between lower anterior facial heights to total anterior facial heights were recorded on the patient's data form to establish the vertical skeletal relationship of the patients. This ratio was correlated with the increased or decreased buccal corridor show during posed smile by applying the Pearson correlation coefficient. Data was analyzed on statistical package for social sciences [SPSS version 10]. Descriptive statistics were used. Mean +/- S.D was calculated for age [in years], vertical skeletal pattern value and the buccal corridor area of subjects. The range of ratio of lower anterior facial height to total anterior facial height [in degrees] was 48[degree sign] to 67[degree sign] with a mean of 56.357[degree sign] and standard deviation of 3.59[degree sign]. The relationship of ratio of lower anterior facial height to total anterior facial height [in degrees] with buccal corridor area show [mm] was significant [P-value < 0.05]. The results show that as ratio of lower anterior facial height to total anterior facial height [in degrees] increases the mean buccal corridor area show decreases. Factors effecting buccal corridor area show must be kept in mind since it has an influence in the outcome of treatment. It is paramount to do so since most patients assess the outcome of their treatment by the attractiveness of their smile

RESUMEN

Orthodontic diagnosis and treatment planning is in a period of remarkable change, away from a previous focus on dental occlusion and hard tissue relationship and towards a greater emphasis on soft tissue adaptation and proportions. The re-emergence of the soft tissue paradigm in clinical orthodontics has made smile analysis and designing, key elements in treatment planning. Hence the purpose of this study was to establish the correlation between one of the many variables effecting smile; the inter-premolar width with the buccal corridor area show of a patient during posed smile. 147 dental casts and frontal photographs were obtained and measured for the inter-premolar width and buccal corridor area show. SPSS version 10 was used to calculate mean and SD for age [in years], inter-premolar width and the inter-commissure width of subjects. Frequencies and percentages were calculated for gender. Pearson correlation coefficient was determined for the inter-premolar width with the buccal corridor area show. r value was determined between -1.0 and +1.0The p value for inter-premolar width and buccal corridor area show during posed smile was < 0.05 being significant. It was concluded from the study that there is a statistically significant relationship between inter-premolar width and the buccal corridor area show during posed smile

RESUMEN

The aim of the study was to determine the frequency and distribution of carious lesions in patients seeking orthodontic treatment. A total of 100 patients including both males and females were recruited consecutively during a one year period. Patients' pretreatment orthodontic records including charts, radiographs and photographs were examined carefully for the presence of carious lesions. Descriptive statistics were used to analyze data. Prevalence of caries was high in the maxilla as compared to mandible. Most frequently involved teeth in both the arches were first molars followed by second molars. An assessment of caries risk of the patients is mandatory before initiating orthodontic treatment in order to gain favorable outcomes of the treatment
