Data obtained was subjected to statistical analysis using SPSS software (Version 20.0). learn more Level of significance was kept at 5%. Intragroup comparison was done using Kruskal-Wallis test followed by Mann-Whitney U-tests for pairwise comparison.

Group 4 showed least mean demineralization in occlusal, middle, and cervical areas as compared to other groups and the results were statistically significant (
< 0.05).

Transillumination can be employed as a method synergistically with conventional curing to achieve minimum amount of demineralization during fixed orthodontic treatment.

To determine the frequency of congenitally missing maxillary lateral incisors (LIs) and to find out its variability in relation to gender.

A retrospective study was carried out between January 2017 and December 2017. Orthopantomographs (OPGs) and lateral cephalographs record search of all orthodontic adolescent patients aged 12 to 18 years were taken from the archival records of the department. Orthopantomographs helped to diagnose the presence of unilateral/bilateral maxillary lateral incisors while the ANB angle was calculated from the lateral cephalographs to divide the subjects into various skeletal malocclusions.

The statistical analysis was done using the Statistical Package for Social Sciences (SPSS version 17.0). The frequencies were compared with the help of the Chi-square test.
<0.05 was considered statistically significant.

The frequency of missing upper laterals among the male patients was 0.9%, however, 2.8% of the female patients were having missing maxillary lateral incisors. Baseas found to be 3.77% in the present study while females were found to have a greater percentage of agenesis of the upper lateral incisors (2.8%) as compared to the males (0.9%).

The study aimed to assess the accuracy and reliability of five cephalometric parameters in diagnosing class III malocclusion in Saudi and Yemeni population.

A cross-sectional, descriptive study in which total 60 lateral cephalograms (30 of Saudi and 30 of Yemeni population) of Class III malocclusion were hand-traced. ANB angle, Wits appraisal, Beta angle, W angle, and Yen angle were measured. The validity, reliability, sensitivity, and positive predictive values (PPVs) of these parameters were calculated.

In Saudi population, a strong correlation was found between ANB angle and Wits appraisal (
= 0.892,
< 0.05), ANB and Beta angle showed highest sensitivity (0.933) followed by Wits appraisal (0.900), and ANB angle showed the highest PPV (0.965) followed by Beta angle (0.933) and Wits appraisal (0.931). In Yemeni population, a strong correlation was found between ANB angle and Wits appraisal (
= 0.887,
< 0.05), ANB angle and W angle showed highest sensitivity (0.966) followed by Wits appraisal (0.933), whereas W angle showed the highest PPV (1.00) followed by ANB angle (0.966) and Wits appraisal (0.933).

In Saudi population, ANB angle and Beta angle, whereas in Yemeni population, ANB angle and W angle are the most valid cephalometric indicators to accurately assess the class III malocclusion. ANB angle in the Saudi population and W angle in the Yemeni population have the highest PPV in correctly diagnosing class III malocclusion.

To evaluate the skeletal, dental and soft tissue cephalometric changes by addition of daytime Class III elastics to the Alternate Rapid Maxillary Expansion-Constriction (AltRAMEC) and Reverse Headgear (RH) protocol in skeletal Class III patients with maxillary retrusion.

54 patients with maxillary retrusion and CVMI (Cervical vertebral maturity index) <CS3 were randomly allocated to an AltRAMEC/RH group (group 1) and AltRAMEC/RH/Class III elastics group (group 2). Each group underwent 5 weeks of AltRAMEC using bonded RME (Rapid Maxillary Expansion) appliance, followed by reverse headgear therapy with a Petit type facemask for 4-5 months. The protraction so obtained was maintained by the use of daytime Class III elastics in group 2. A total of twenty skeletal, dental and soft tissue parameters were evaluated by a blinded examiner. Results were evaluated statistically.

Significant forward movement of the maxilla with counter-clockwise rotation, improved intermaxillary relationships, downward and backward movement of the mandible, and favourable soft tissue changes were observed in both the groups under study. The results were more pronounced in group 2. Increase in vertical dimensions, proclination of maxillary and retroclination of mandibular incisors was also observed. Statistically significant differences were present between the two groups for all of the maxillary and mandibular skeletal, intermaxillary and two of the soft tissue parameters tested; while the differences were not found to be significant for dental parameters.

Addition of Class III elastics to the AltRAMEC/RH protocol yielded more pronounced, favourable and statistically significant results.

To compare airway widths among skeletal Class I malocclusion patients with different vertical facial patterns.

A total of 103 lateral cephalograms of skeletal Class I patients (mean age of 20 ± 2.3 years) with no history of orthodontic treatment, trauma, facial syndromes, or nasopharyngeal dysfunction were included. Based on the Frankfort-mandibular plane angle measurements, the sample was divided into three groups low-angle, high-angle, and normal-angle groups. Upper and lower pharyngeal airway widths were measured as described by McNamara. The analysis of variance test was performed to compare the means of groups. Pairwise comparisons were performed using Tukey's post-hoc test. Differences were considered statistically significant at
< 0.05.

ANOVA showed a significant mean difference between the groups for both the upper and lower airway widths with
values of 0.011 and 0.003, respectively. Tukey Pairwise comparisons showed the upper airway width to be significantly narrower in the high-angle group compared to the normal-angle (
= 0.
