Comparative Evaluation of Nemoceph and Foxit PDF Reader for Steiner’s Cephalometric Analysis

Cephalometry is used to quantify and qualify the type of malocclusion. The digital technology has overcome the limitations of manual method. A high cost of the commercially available software is unaffordable for its wide spread use. Objectives: The aim of this study was to evaluate and compare the values of Steiner’s cephalometric analysis using Nemoceph and Foxit PDF reader. No significant difference between the two methods will result in that Foxit PDF reader can be used as an cost effective alternative. Methods: This study was conducted on 100 digital lateral cephalogram taken from the same machine. The samples were collected by non-probability convenience sampling procedures. These images were analyzed for Steiner’s Cephalometric Analysis using the two software. Results: The skeletal and dental values showed no statistical significant difference in the majority, except for the L1-NA (Linear) and L1-NB (Linear). Conclusion: Results showed that there is a high agreement between the two methods.

Comparative Evaluation of CEPH Ninja for Android and Nemoceph for Computer for Steiner’s Cephalometric Analysis

Orthodontics and Dentofacial Orthopaedics, requires a cautious acquisition and interpretation of a large amount of information to achieve a correct diagnosis and treatment planning. Manual techniques are time consuming and tedious. The digital technology is advantageous but the affordability remains obstacle. Objectives: The main aim of this study was to compare the linear and angular measures between the two methods, Ceph Ninja and Nemoceph. No significant difference between the two methods will result in that Ceph Ninja can be used as an alternative. Methods: This study was conducted on 100 digital lateral cephalogram taken from the same machine. The samples were collected by non-probability convenience sampling procedures. These images were analyzed for Steiner’s Cephalometric Analysis using the two software. Results: The results of this study showed the skeletal and dental values had no statistical significant difference in the majority, except for the linear values of Lower Incisor and Upper Incisor with N-A and N-B respectively. Conclusion: It seems that the two software can be used interchangeably with high confidence.

Is Orthodontic Treatment Fearful?

Objective: To evaluate the anxiety level of prospective orthodontic patients. Methods: Dental Anxiety ScaleRevised (DAS-R) questionnaire was modified and filled by 101 subjects (53 females and 48 males) visiting for their orthodontic treatment. Results: 62.4 % patients had no or low anxiety levels and 9.9% and 5.9% showed high to severe anxiety levels respectively. There was no statistical significant difference seen between the anxiety levels in male and female patients. Conclusions: 37.6 % patients for orthodontic treatment showed moderate to severe anxiety levels with no significant difference seen in the overall anxiety levels between the genders.

Do Braces Causes Caries?

Attaining improved aesthetics and proper occlusion are main reasons for commencing orthodontic treatment in any patient. However it is anticipated that orthodontic treatment increases the risk of carious lesions. Objective: To analyze prevalence of dental caries in relation to gender, age group, duration of orthodontic treatment and malocclusion type; and to assess oral hygiene and food habit practice in young orthodontic patients. Methods: A cross sectional study was done in 212 orthodontic patients (age range 11-30 years) having fixed appliance for at least six months duration. A survey form based on ‘Dentition Status & Treatment Need, WHO’ was used to depict DMFT Index and prevalence of dental caries. A questionnaire was used to assess the practice of oral hygiene measures and food habits of the orthodontic patients. The association between dental caries and gender, age group, duration of orthodontic treatment and malocclusion type were analyzed using chi-square test (p<0.05). Results: The prevalence of dental caries (DMFT) was 79.2% and mean DMFT value was 2.87 among orthodontic patients studied. Occurrence of dental caries among male and female patients was 69.44% and 60% respectively. Caries occurrence was highest in age group 16-20 years (72.22%), in more than 18 months treatment duration group (63.92%) and in Class I malocclusion group (68.38%). Similarly, 30.2% consume sweets foodstuff, 26.9% consume junk food and 14.2% consume snacks in between meals frequently. Conclusions: Fairly good proportion of orthodontic patients practice normal oral hygiene methods but very few use special oral hygiene measures. The study showed no association between dental caries occurrence and gender groups, age groups, duration of orthodontic treatment and malocclusion types.
