The Relationship

Smile is one of the facial expression that are essential in expressing friendliness, agreement, and appreciation. Most patients that come to dentist to have treatment for an attractive smile. One of the component to make an attractive smile is smile arch. Smile arch have been the interest of the orthodontist in recent years. Smile arch is the relationship between a hypothetical curve drawn along the edges of the maxillary anterior teeth and the inner contour of the lower lip in smile. This study was to differ male and female’s smile type base on smile arch. This study was to evaluate of smile type based on smile arch with gender. A total of 31 females and 31 males were selected among criteria inclusion. Photographs taken with digital camera showing the subjects with a posed smile were used for this study and Adobe photoshop used to determine the smile arch. Student Mann Whitney test were used for statistical analysis. The resulting data showed that significantly difference (p<0,05) between smile arch and gender. The most common female’s smile are parallel smile (64.5) and male’s smile are straight smile (51.6%). In this study concluded that the curvature of the incisal edge anterior maxilla appears to be more pronounced or parallel for woman than for a men.

Objective: To establish soft-tissue cephalometric norms of Kashmiri population and to compare them with European-American norms. Material and Methods: A total of 102 subjects falling in the age group of 19 to 25 years were selected from random and representative sample of 5317. Reference lines were traced according to the definitions given by Holdaway, Rickett, Steiners, Merrifield, and nasiolabial angle. Thirteen linear and 4 angular measurements were analyzed on the lateral cephalogram of the sample. Results: Significant differences were found between male and female subjects in measurements of the soft-tissue facial angle, upper lip thickness, upper lip strain, lower sulcus depth and soft-tissue chin thickness, and upper lip to S line and nasiolabial angle. Soft-tissue cephalometric norms of Kashmiri population that were measured in the present study when compared with the norms set by Holdaway’s parameters, Rickett’s E line, Merrifield Z angle, Steiner’s S line, and nasiolabial angle did not fall within the normal range. The facial angle was found to be greater by 1.36°, upper lip sulcus depth was greater by 0.53 mm, convexity at point A was greater by 2.43 mm, the H angle was greater by 5.64°, upper lip thickness and strain were greater by 2.30 and 2.36 mm, respectively, soft-tissue chin thickness was greater by 0.92 mm, upper lip to S line was greater by 0.60 mm, and lower lip was greater by 0.91 mm when compared with the standard European-American norms. Conclusion: According to the present study, the measured soft-tissue cephalometric norms for Kashmiri population differed from the standard norms. When planning orthodontics treatment, it should be kept in mind that the profile may not necessarily be orthognathic.

Context There has always been a need for nonnumeric facial analyses that would not compare an individual’s facial measurements with the preestablished norms, rather evaluate the facial form individually. This would help in diagnosis and treatment planning, unique to that individual. Aims The purpose of the study was to determine and establish a relation between skeletal, dental and soft tissue structures using centrographic analysis (CGA) in pleasing faces of Western Uttar Pradesh population. Materials and Methods A total of 50 subjects (22 males and 28 females) with “most pleasing faces” were taken up for the study, within the age group of 20-25 years. Frontal facial photographs and lateral cephalograms were taken for all the subjects. Conventional cephalometric analysis and CGA were applied to each lateral cephalogram. Arithmetic mean and standard deviation values were calculated, and an independent t-test was performed for calculating cephalomorphic norms and comparison between the male and female sample. Results The results showed that, the adults in the age group of 20-25 years, belonging to the Western Uttar Pradesh population have protrusive maxillary and mandibular skeletal bases and retrusive upper lip on contrary to a protrusive lower lip, though a sexual dimorphism was observed. The upper centroid and lower centroid values were statistically greater in women (P = 0.05 and P = 0.04 respectively) whereas, upper lip linear value was statistically greater in men. Conclusions The CGA is valid for Western Uttar Pradesh population. The Western Uttar Pradesh adults have protrusive mandible and a retrusive upper lip though there exists a sexual dimorphism. These practical centrographic norms can be used as an adjunct to the conventional cephalometric evaluation of an individual for diagnosis and treatment planning.

Treatment Plans

To conduct a successful orthodontic treatment, we must understand a key concept and fundamental: aesthetics. Despite being a concept extremely subjective and influenced by culture, there are some features we can evaluate. An optimal smile is characterized by an upper lip that reach the gingival margins, with a curve or straight up between the philtrum and the corners, a line coincident with the upper incisal edge of lower lip minimal or absent negative spaces; commissural line and frontal occlusal plane parallel to the pupil, and some gum and dental components harmoniously integrated. Only when individualized and developed treatment plans for each patient, we can obtain acceptable aesthetic results.

INTRODUCTION: A female patient aged 12 years and 2 months had molars and canines in Class II relationship, severe overjet (12 mm), deep overbite (100%), excessive retroclination and extrusion of the lower incisors, upper incisor proclination, with mild midline diastema. Both dental arches appeared constricted and a lower arch discrepancy of less than -6.5 mm. Facially, she had a significant upper incisors display at rest, interposition and eversion of the lower lip, acute nasolabial angle and convex profile. OBJECTIVE: To report a clinical case consisting of Angle Class I malocclusion with deep overbite and overjet in addition to severe crowding treated with a conservative approach. METHODS: Treatment consisted of slight retraction of the upper incisors and intrusion and protrusion of the lower incisors until all crowding was eliminated. RESULTS: Adequate overbite and overjet were achieved while maintaining the Angle Class I canine and molar relationships and coincident midlines. The facial features were improved, with the emergence of a slightly convex profile and lip competence, achieved through a slight retraction of the upper lip and protrusion of the lower lip, while improving the nasolabial and mentolabial sulcus. CONCLUSIONS: This conservative approach with no extractions proved effective and resulted in a significant improvement of the occlusal relationship as well as in the patient's dental and facial aesthetics.

Speech Articulators

Inferior-superior displacements of the upper lip, lower lip, and jaw were transduced with a strain-gauge system in 4 normal-speaking adults. Movements of the upper and lower lips were compared across conditions in which the jaw was free to move and when bite blocks were used to fix the jaw at four different vertical positions. As jaw-open position was increased with the bite blocks, it was found that: (a) Positions of both lips changed for bilabial closure, but the closing movements did not usually maintain consistent proportions between lips across different bite-block sizes; (b) although the lips maintained fairly consistent maximum interlabial opening across many conditions, this opening was reduced in the small bite-block conditions; and (c) in a few cases there was an increase in the duration of lip-closing movements, but these were small and inconsistent. The findings are discussed relative to possible organizational systems that would produce the observed interactions among speech articulators.

Consonant Voicing

This paper reports two experiments, each designed to clarify different aspects of bilabial stop consonant production. The first one examined events during the labial closure using kinematic recordings in combination with records of oral air pressure and force of labial contact. The results of this experiment suggested that the lips were moving at a high velocity when the oral closure occurred. They also indicated mechanical interactions between the lips during the closure, including tissue compression and the lower lip moving the upper lip upward. The second experiment studied patterns of upper and lower lip interactions, movement variability within and across speakers, and the effects on lip and jaw kinematics of stop consonant voicing and vowel context. Again, the results showed that the lips were moving at a high velocity at the onset of the oral closure. No consistent influences of stop consonant voicing were observed on lip and jaw kinematics in five subjects, nor on a derived measure of lip aperture. The overall results are compatible with the hypothesis that one target for the lips in bilabial stop production is a region of negative lip aperture. A negative lip aperture implies that to reach their virtual target, the lips would have to move beyond each other. Such a control strategy would ensure that the lips will form an air tight seal irrespective of any contextual variability in the onset positions of their closing movements.

The paper aims to describe the articulatory traits of the Baraba-Tatar phoneme o /ʊ̇/ by the somatic methods. The method used is magnetic resonance imaging (MRI). Eighteen Barabian tomograms comprising o-type articulation have been described and analyzed according to the technique adopted in the V. M. Nadelyayev’s Laboratory of Experimental-Phonetic Researches (Institute of Philology SB RAS). The text provides only general observations and conclusions, with a full description of all tomograms given in three tables. The experimentalphonetic analysis of the Baraba-Tatar tomograms of the vowel o allowed the author to draw several conclusions. There is a variability of the o-type tunings in Barabian, the most typical being the central-back narrow labialized ejective realization. Though it is very narrow and is phonetically transcribed as /ʊ̇/, it is acoustically perceived as o. While producing the sound o, the oral and pharyngeal cavities become very small, producing the effect of tension. Additional narrowing occurs between the soft palate and the tongue back as well as between the upper teeth and the lower lip, thus preventing the airflow from free release. The lip position is also unusual: instead of protruding forward, the upper lip moves back, tightly covering the upper teeth to produce an interesting acoustic effect. To sum up, further investigation of all vocal system units of Baraba-Tatar is needed to draw ultimate conclusions about the typological belonging of the language under consideration.

Functional Problems

Double lip or macrocheilitis is a rare facial anomaly, mostly congenital in origin. It commonly involves the upper lip than the lower lip. It may occur in isolation or as part of the Ascher’s syndrome. It results due to deposition of excessive areolar tissue and non-inflammatory hyperplasia of labial mucosa gland of pars villosa. It may be acquired as a result of injury to the lips or lip-biting habit. The double lip becomes conspicuous when the lips are retracted during smiling resulting in the characteristic ‘cupid’s bow’ appearance. This disfigurement can pose aesthetic and functional problems and may result in psychological distress. A surgical intervention is must for restoration of functions and to address the aesthetic concerns. The present article reports a case of non-syndromic double upper lip with triple labial frena and its surgical management with laser on one side and with scalpel on the other side.
