Prevalence of Malocclusion in Jaipur, India

A study was undertaken to determine the prevalence of malocclusion in Jaipur city, India. A total of 700 subjects, in the age group of 16-26 years were divided into five groups of normal occlusion, Angle’s Class I, Class II Div 1, Class II Div 2 and Class III malocclusion. The results revealed that the prevalence of malocclusion was 66.3%, with the majority of them having Class I malocclusion (57.9%), while the prevalence of Class III malocclusion was found to be the least (1.4%). There was no statistically significant gender difference among the subjects studied.

Applicability of Bolton's Analysis: A Study on Jaipur Population

ABSTRACT This study was undertaken to compare the Boltons anterior and overall ratios among males and females in Jaipur population. One hundred study models (50 males and 50 females) of orthodontic patients were randomly selected from the Department of Orthodontics, Mahatma Gandhi Dental College, Jaipur. The normative data for the mesiodistal widths of males and females were established and the anterior and overall ratios were obtained for both males and females. It was observed that were no significant differences in both the ratios in males and females. Hence, both the ratios were obtained for the sample as a whole. These ratios were found to be similar to the Boltons standard with no significant differences. Therefore, it can be concluded that Boltons standards can be applied to this population irrespective of sex or ethnic background. How to cite this article: Trehan M, Agarwal S, Sharma S.

Comparison of Effectiveness of Manual Orthodontic, Powered and Sonic Toothbrushes on Oral Hygiene of Fixed Orthodontic Patients.

ABSTRACT Introduction: Maintenance of good oral hygiene is important for patients undergoing fixed orthodontic treatment. Aim: The aim of this study was to evaluate the effectiveness of a manual orthodontic toothbrush, powered toothbrush with oscillating head and sonic toothbrush in controlling plaque, gingivitis and interdental bleeding in patients undergoing fixed orthodontic treatment, and to compare their relative efficacy. Materials and methods: Sixty subjects, who were to receive orthodontic treatment with both upper and lower fixed appliances, were randomly divided into three study groups, with 20 patients in each group. Groups I to III were given manual orthodontic, powered and sonic toothbrushes, respectively. Plaque index (PI), gingival index (GI) and interdental bleeding index were scored to assess the level of plaque accumulation, gingival health and interdental bleeding at baseline; 4 and 8 weeks recall visits after fixed appliance bonding. Paired t-tests and one-way analysis of variance (ANOVA) tests were used for intragroup and intergroup comparisons. The level of statistical significance was set at p < 0.05. Results: This study showed that a significant reduction in all the three indices scores was found from baseline to 4 and 8 weeks in group III. On intergroup comparison, no statistically significant differences were detected between the three groups for any of the parameters assessed. Conclusion: On intragroup comparison, sonic brushes performed superiorly in reducing gingivitis, plaque and interdental bleeding as compared to the manual orthodontic and powered brushes. On intergroup comparison, the relative comparative effectiveness was found to be similar for all the three brushes. How to cite this article: Sharma R, Trehan M, Sharma S, Jharwal V, Rathore N.

Submental intubation: A useful adjunct in panfacial trauma.

Complex maxillofacial trauma requires a modification of intubation as it precludes both oral and nasal intubation. Tracheostomy is not preferred due to its associated complications. Submental intubation comes as a rescue in such situations as it provides an uninterrupted access to the operative field with due control over airway and minimal side effects.

Pediatric mandibular fractures: a review.

The pattern of craniomaxillofacial fractures seen in children and adolescents varies with evolving skeletal anatomy and socioenvironmental factors. The general principles of treating mandibular fractures are the same in children and adults: Anatomic reduction is combined with stabilization adequate to maintain it until bone union has occurred. But recognition of some of the differences between children and their adult counterparts is important in long-term esthetic and functional facial rehabilitation as effect of injury, treatment provided has a great influence on their ensuing growth.

Childhood Obesity: Review of a growing Problem.

Abstract The consequences of obesity in adulthood are well known. Obesity has a direct influence on mortality and acts as a risk factor for various diseases and health problems. It is associated with nonfatal but debilitating illnesses, such as respiratory difficulties, musculoskeletal disorders, skin problems and infertility. The association with fatal chronic diseases includes cardiovascular diseases, conditions related to insulin resistance and noninsulin-dependent diabetes. There has been a marked increase in the number of obese children coming for treatment to dentists, thus it is the moral responsibility of the dentists to educate both the patient and the parents of the problems of obesity and its control. A dentist may actually be the first person to inform the patient about this problem thus, a basic knowledge about it is important. How to cite this article: Shivpuri A, Shivpuri A, Sharma S.

Recurrent Unicystic Ameloblastoma of the Infratemporal and Temporal Fossa

The ameloblastoma has been described as benign but locally invasive; benign and locally invasive with strong tendency to recur; and locally malignant. Recurrence of this lesion in to the infratemporal and temporal region are rarely reported cases. Complete excision of lesion was done with the help of the advance imaging modalities and possible cause of recurrence in this case is discussed.

Assessment of Skeletal Maturity by Correlating Insulin Like Growth Factor-1 with Hand-Wrist Radiographs: An in vivo Study

Introduction: Hand-wrist radiography have been the method of choice for assessment of skeletal maturity. However, additional radiographic exposure and subjectivity of staging makes the use of hand-wrist radiographs questionable. Insulin-like Growth factor 1 (IGF-1) is a circulating growth hormone dependent factor whose levels correlate with growth spurt. Study evaluates use of IGF-1 levels as skeletal maturity indicator. Aims and objectives: To compare mean IGF-1 levels at different stages of skeletal maturity using hand wrist radios and to assess whether serum IGF-1 levels can be used as skeletal maturity indicator. Materials and methods: Hand-wrist radiographs and blood samples of 45 subjects were collected. Staging of hand-wrist radiographs was done according to Bjork, Grave and Brown method. The IGF-1 serum levels in different stages of skeletal maturity were compared. Results: ANOVA and post hoc Tukey test showed that IGF-1 levels at pubertal stage were significantly higher than the prepubertal and postpubertal phases. Conclusion: IGF-1 levels were significantly higher in pubertal stage as compared to prepubertal and postpubertal stages. IGF-1 levels might prove to be a valuable skeletal maturity indicator.

Comparison of Shear Bond Strength and Estimation of Adhesive Remnant Index between Light-cure Composite and Dual-cure Composite: An in vitro Study.

ABSTRACT Aims and objectives: To measure and compare the shear bond strength and adhesive remnant index of light-cure composite. (Enlight, Ormco.) and dual-cure composite (Phase II dual cure, Reliance Ortho). Materials and methods: Sixty extracted human premolar teeth were divided into two groups: group I (blue): conventional light cure composite resin. (Enlight, Ormco.) and group II (green): dual cure composite resin. (Phase II dual cure, Reliance Ortho.) with 30 teeth in each group. These samples were tested on the universal testing machine to measure the shear bond strength. Results: Student t-test showed that the mean shear bond strength of the conventional light cure group (8.54 MPa - 10.42 MPa) was significantly lower than dual cure group (10.45 MPa -12.17 MPa). Conclusion: These findings indicate that the shear bond strength of dual-cure composite resin (Phase II dual cure, Reliance Ortho) is comparatively higher than conventional light-cure composite resin (Enlight, Ormco). In the majority of the samples, adhesive remnant index (ARI) scores were 4 and 5 in both the groups whereas score 1 is attained by the least number of samples in both the groups.

Perception of Facial Profile: How You Feel About Yourself

Objective The aim of this study was to determine how aware the individuals were of their own profile and to compare the orthodontist’s perception of an attractive facial profile with those of laypeople, dental students and orthodontic patients. Materials and methods The study comprised of a total of 200 subjects divided into four groups of 50 subjects each: Laypeople, first-year dental students, final-year dental students and orthodontic patients. Participants answered a questionnaire regarding facial profile and their expectations from orthodontic treatment. The facial profile photographs of participants were analyzed by two orthodontists separately who matched the individual to the depicted silhouettes. Agreement between participants and orthodontists was evaluated by using the statistic χ2 test. Results Dental students and orthodontic patients were more aware of their facial profile as compared to the laypeople. The four groups were different in their abilities to recognize their own profiles. The difference in profile perception between orthodontists and subjects was statistically significant (p < 0.05). Conclusions Class I profiles were perceived to be the most attractive by all the groups and profiles with a protrusive mandible were perceived to be the least attractive. Final-year dental students and orthodontic patients were more accurate in identifying their own profile.
