Abstract

Background: The aim of the present study is to evaluate the esthetic smile in sample of Iraqi adults and to assess thegender differences.Materials and Methods: 100 persons (50malesand 50 females had class I normal dental and skeletal selected for thisstudy.Clinical examination and digital photograph with posed smile were performed for each individual. Six linearsoft tissue parameters in each photograph using AutoCAD program 2011.Five visual and four quantitative evaluations of the smile were studied for eachsubject. The smile arch and index,buccal corridor spaces (BCSs) were studied.Descriptive statistics of the measurements were calculated. Independentstudent’s ttestswere used to evaluate the gender differences.Statistics: Descriptive statistics and Standard error of each measurement was calculated. Independent sample t-testswere used to compare the measurements of male and female subjects. Chi square used for visual measurements.Results and conclusion: The average smile, parallelism of the upper incisal curve with the inner curvature of the lowerlip, 1:1 ratio of the widths of nose and upper cuspid were higher in females than males while in smile curve arch linewithout touching the lower lip the opposed and 2nd premolars are the most common display in both groups.Femalesshowed higher than five smile index indicate a constant well balanced smile in females than in males, Femalesshowed a well-balanced expression with posed smile, A medium buccal corridor in both females and males

Abstract

Background: The human face is a living mirror held out to the world. Natural, marked, painted or adorned, it haspower to attract, charm, captivate or brighten. Therefore the subject of the smile and facial animation, as theyrelate to communication and expression of emotion, should be of great interest to orthodontists so the aims of thisstudy were to determine the difference of outer commissure width, inter-labial gap, smile index, modified smile index,visible maxillary interdental width, buccal corridor percentage and maximum incisor show among different smilestyles (Monalisa, Cuspid and complex) during emotion, posed smile and speech. And to determine the differences ofthe same variables for each smile style among emotional smile, posed smile and speech.Materials and methods: The sample consisted of 77 Iraqi adult subjects (18-30) years with skeletal class I occlusion,classified into three categories according to a certain neuromuscular mechanism of smile called smile style, the firstgroup consisted of 34 (24 male, 10 female) subjects with Monalisa smile style, the second consisted of 34 (22 male, 12female) subjects with Cuspid smile style, the last 9 subjects (5 male, 4 female) were the third group with Complexsmile style. Each subject was recorded using digital videographic camera while watching a comical movie to elicitemotional smile, then they asked to say “Chelsea eats cheesecake” to record them during speech. The videographswere imported to the PMB-picture motion browser to capture emotional smile, posed smile and speech frames. Fourlinear measurements were measured for each frame using AutoCAD program 2011.Results: The results of this study showed that all the variables changed significantly when the subject change fromspeech to emotional smile frame in all smile styles. And these changes revealed almost the same behavior when thesubject changed from speech to pose or to emotional smile frames.Conclusion: The result of this study revealed that emotional smile is largely different from posed smile in differentaspects which has an effect on decisions related to orthodontic diagnosis and treatment plan

Abstract

Every now and then, we face the problem of terminally ill patient or what looks incurable lesion, like disseminated malignancy. Certainly, all of us prefer not to face such a bitter reality. But sadly, this is unavoidable. Problems almost always arise from this type of patients if not from their relatives, hence, the importance of proper handling, fine communication, gentle words and precise estimation of the surgeon's sentences. By doing so, the surgeon can spare himself a lot of problems. Sorry to say, some surgeons fall in this trap because they mishandle these peculiar and difficult patients. It is vital to appreciate the psyche of those miserable patients, sympathize with them as much as possible, make them feel that you are serious and keen to help them, and you are a friend rather than a physician.

Abstract

Background: lip lengthening procedure is one of the surgical options for the correction of gummy smile in patients with short upper lip.Methods: A comparative clinical study was conducted on 15 patients requiring lip lengthening procedure for the esthetic correction of excessive gingival exposure with gummy smile. Scalpel was used in seven patients and diode laser in the remaining eight patients. Under infiltration anesthesia, about one cm strip of mucosa was excised at the vestibular depth and the mucosa of the lip was sutured to the alveolar mucosa.Results: The diode laser group demonstrated less postoperative pain and swelling. Regarding postoperative ecchymosis, three patients in the scalpel group developed ecchymosis and no cases were noted in the laser group, the difference was statistically significant. No patient in the laser group developed wound dehiscence and only one patient in the scalpel group had wound dehiscence at third postoperative day. Observed at one month postoperatively, the laser treated groups had less obvious scar than the scalpel group.Conclusion: Diode laser is a valuable tool in performing lip lengthening for gummy smile

Abstract

Our objectives were to evaluate and quantify upper lip soft-tissue changes in the vertical dimensions both at rest and at maximum smile. Methods thirty three volunteers (15 men, 18 women) aged 18 to 23 (mean, 21.5 years) were recruited for this study. For each subject, 8 measurements of upper lip position and maxillary incisor crown height at rest and in maximum smile were recorded. Results: A statistically significant sexual dimorphism was apparent in most of the measured variables. Relaxed external upper lip length was 1.8 mm mm shorter in the women than in the men. The mean maxillary central incisor length was 0.56 mm greater in the men than in the women. A low smile line was more prevalent in the women, The average smile is more prevalent in male than female. Conclusions: Data from this study clearly indicate sexual dimorphisms in upper lip length, maxillary incisor display, and resting external upper lip length. Low smile patterns are more common among female patients, and also common among male patients while high smile are less common among female and male patients. The average smile is more prevalent in male than female.

الهدف من هذه الدراسة هو لتقييم وتحديد تغيرات الشفه العليا في البعد الافقي للوجه خلال كل من الاستراحة والابتسامة. شملت الدراسة ثلاثة وثلاثين متطوع (15 رجال , 18 نساء) تتراوح اعمارهم بين 18 سنه و23 سنه. سُجل لكل شخص 8 قياسات للشفه العليا خلال الاستراحة وخلال الابتسامة وايضا شملت قياس طول القاطع المركزي العلوي. اظهرت النتائج بان هناك فرق معنوي في اغلب القياسات بين الرجال والنساء فطول الشفه العليا عند الاستراحة كان 1.8 ملم اقصر عند النساء من الرجال وكان طول القاطع المركزي حوالي 0.56 ملم اطول عند الرجال من النساء. كانت الابتسامة المنخفضة هي السائدة بين النساء, وكانت
