Comparison between ibuprofen and chewing gum for orthodontic pain control

Pain is common experience in orthodontic patients that begins two hours after force application and reaches peak at 24 hours, then lasts for 5 to 7 days. The objective of this study was to compare the decrease in pain score with ibuprofen and chewing gums in orthodontic pain control during the first week after initial arch wire placement. This study was conducted at de,Montmorency College of Dentistry, Lahore, from April 2014 to October 2014. 250 patients with age range of 12 to 16 years of both sex were selected and divided in to ibuprofen and chewing gum groups [125 each group] using random number table. The patients in each group received pain control 24 hours after initial arch wire insertion and then at 8-hour interval till 7th day. Patients were asked to complete a Visual Analog Scale [VAS] Questionnaire, at 24 hours after arch wire insertion, then at 24 hours, and 7th day. Two-way ANOVA was used for analyzing significance of mean decrease in VAS between two groups. Results showed that decrease in pain score for ibuprofen group; baseline to 24 hours was 2.35 +/- 1.36 which was significantly lower than decrease in pain score for chewing gum group 3.34 +/- 1.34. At 7th day, ibuprofen group showed decrease in pain score as 4.07 +/- 1.43 which was significantly lower than decrease in pain score of 5.86 +/- 1.56 for chewing gum group. This was concluded that chewing gums showed more decrease in pain score for orthodontic patients as compared to ibuprofen

Comparison of Jones JIG and distal jet molar distalizing appliances

The purpose of the present study was to evaluate and compare the effects of Jones jig and distal jet appliance during class-II molar correction with maxillary first molar distalization, its tipping, extrusion, rotation as well as anchorage loss at premolar-incisor unit. Sixty patients were selected from Orthodontics department de,Montmorency College of Dentistry, Lahore, Pakistan and pre and post distalization lateral cephalograms and study casts were used as evaluation tools. Distal jet group showed 3.88 mm space creation during 7.11 months, out of which 2.93 mm [75.52%] was molar distalization while 0.93 mm [24.48%] was premolar mesialization as anchorage loss. There was 3.41§ molar tipping with 0.20 mm extrusion and 7.33 § distal tipping with 0.90 mm second cuspid extrusion whereas incisors had 1.65 § labial tipping. Right and left upper molars showed 1.30° and 1.18° rotation respectively. In the Jones jig group, the maxillary first molars were distalized to 3.30 mm on each side and tipped 6.70° distally. The maxillary second premolars moved mesially 2.00 mm with tipping of 7.48°.Therefore a total space created between first molar and second premolar was 5.30 mm i.e. 62.26% from first molar distalization while 37.74% from second premolar mesialization. In addition maxillary first molar extruded 0.70 mm and second bicuspid extruded 1.58 mm. Both right and left first molars were also disto-palatally rotated by 2.00° and 2.55° respectively though upper incisors showed 2.25° proclination during distalization. Distal jet appliance was found to be a more effective and predictable method for themaxillary first molar distalization through bodily translation with minimum tipping, extrusion, and rotation as well as anchorage loss

Effects of distal jet appliance in class-II molar correction

This study was conducted on a sample of thirty patients selected from Orthodontics department de'Montmorency College of dentistry/ Punjab dental Hospital, Lahore.

Pre and post distalization lateral cephalogram and study cast were used as evaluation tools. Results showed that there was 3.88 mm space created during 7.11 months; out of which 2.93 mm [75.52%] showed molar distalization while 0.93 mm [24.48%] premolar mesialization as anchorage loss. There was 3.41% molar tipping with 0.20 mm extrusion and second premolar showed 7.33% distal tipping, 0.90 mm extrusion whereas Incisors showed 1.65% labial tipping

Prevalence of crossbite in orthodontic patients

The objective of the present study was to evaluate the prevalence of cross bite in patients reporting for orthodontic treatment. Pretreatment study casts of 100 patients were selected from the model store of the Orthodontics Department .Faculty of Dentistry, The University of Lahore. SPSS [10.0] was used to analyze the data. 24% of the patients had cross bite. Of these 25% were male patients while 75% were female patients

Co-relation between ANB angle, Wits value and SNP plane angle

ANB angle and Wits value are used to asses the Sagital pattern of the patient cephalometrically. The two variables are dependent on change in theAntero-posterior and vertical position of Point A. SNP plane angle determines the rotation change in position of Palatal plane with reference to SN plane. This rotational change might have an impact on the position of point A and thus the ANB angle and Wits value. Aim of the study was to establish correlation between ANB, Wits Value and SNP plane angle. Study was conducted on 60 subjects and following conclusions were drawn. 1. Statistically significant correlations was found between ANB angle and Wits Value 2. Statistically insignificant correlation was found between SNP plane angle and ANB and Wits Value suggesting that rotational change in this Palate with reference to SN plane has no impact on the sagital assessment parameters 3. Statistically significant correlations was found between

Orthodontic treatment need at de, Montmorency college of dentistry Lahore, using the aesthetic component of IOTN index

Although work has been done in Pakistan to determine the orthodontic treatment need of patients, but till now no study had been done to evaluate the orthodontic treatment need on aesthetic basis. Aesthetic Component [AC] of Index of Orthodontic Treatment Need [IOTN] was used on a sample of 100 pretreatment study casts of the patients at de'Montmorency College of Dentistry, Lahore Pakistan, to evaluate the aesthetic need for orthodontic treatment. The data was statistically analyzed by SPSS [8.0]. Overall it was found that 41% of the cases needed definite orthodontic treatment. 37% of female patients and 52% of male patients needed definite orthodontic treatment. 41% of the patients were classified as being in need of moderate orthodontic treatment, with 18% having no orthodontic treatment need. Aesthetic Component grade 8 was shown by 26% of cases. Results of the study showed a high number of patients in need of the orthodontic treatment

Prevalence of deep bite in orthodontic patients

The aim of the present study was to evaluate the deep bite status of orthodontic patients. Sample consisted of 100 pre-treatment study casts of patients at the Orthodontics department de, Mantmorency College of Dentistry, Lahore. The data was statistically analyzed by SPSS [8.0]. Overall, it was found that 7% patients had open bite. 17% showed normal value of incisor over bite, while 76% patients showed varying values of deep bite. Out of these 76 patients [76%], 28% were male and 72% were female patients. As far as the distribution of these 76 patients in different categories of deep bite is concerned. Maximum number of patients; 92% of these were having mild to moderate degree of deep bite while only 8% showed full coverage of lower incisor crowns

Effectiveness of an oral hygiene program for patients undergoing fixed orthodontic treatment

The aim of the present study was to assess the effectiveness of an oral hygiene program for patients undergoing fixed orthodontic treatment. Main sample consisted of one hundred patients with an age range of 12-25 years, having a full complement of permanent dentition, reporting to the orthodontic department of the de, Montmorency College of Dentistry, Lahore. Community Periodontal Index was used to assess the periodontal status of these patients. From these 100 patients, 20 patients having good oral hygiene and in need of fixed orthodontic treatment were divided into experimental and control groups, and their periodontal status was assessed before and during fixed orthodontic treatment. Modified Bass toothbrushing technique and the relation between the fixed orthodontic appliances, plaque accumulation and gingival inflammation were explained to the experimental group. Data was analyzed by using SPSS [Version 8.0] in personal computer. Results showed although no significant differences were noted in the periodontal status of experimental and control groups, but as a group, control group patients showed more statistically significant deterioration of periodontal health as compared to the experimental group

Class- III - malocclusion: a cephalometric study in a Pakistani population sample

This study was carried out to evaluate the Cephalometric characteristics of class-III malocclusion in a sample of Pakistani population with age range 18-25 years visiting Orthodontics department, de' Montmorency college of Dentistry / Punjab dental hospital, Lahore. Lateral Cephalometric radiographs, Orthopentomograms, Study casts, extra oral and intra oral photographs were taken for every patient. Results indicate that regarding the Cephalometric characteristics of Pakistani patients with class III malocclusion, the Maxilla showed retrognathism in relation to cranial base both for angular and linear parameters in antero-posterior relationship while the Mandible showed prognathism in relation to cranial base both for angular and linear parameters in antero-posterior relationship. However the Dento-alveolar measurements showed maxillary incisors proclination and mandibular incisors retroclination, suggestive of dental compensation to skeletal discrepancy. Males showed comparatively horizontal while females exhibited vertical growth tendency

Effects of jones jig appliance in maxillary first molar distalization

The purpose of this study was to evaluate treatment effects of Jones jig appliance during class-II molar correction with a focus on the magnitude of maxillary first molar distalization, its tipping, extrusion and rotation as well as anchorage loss at premolar- incisor unit. A complete set of pre and post distalization records including history, clinical examination, Lateral cephalometric radiograph, Orthopentomogram, study casts and photographs was taken for each patient. Pre and post distalization lateral cephalometric radiographs were traced for evaluation of molar, premolar and incisors movements while models were used to find out molars rotation. Results showed that there was 5.30 mm space created between molar and premolar during 5.65 months; out of which 3.30 mm [62.26%] showed molar distalization and 2.00mm [37.74%] anchorage loss. There was 6.70° molar tipping with 0.70 mm extrusion while second premolar showed 7.58° tipping and 1.58 mm extrusion. Incisors exhibited an insignificant labial tipping of 0.75°. Both right and left molars showed 2.00° and 2.55° highly significant disto palatal rotation

Dental crowding and its relationship to tooth size and arch dimensions

Tooth size arch length discrepancy [TSALD] is a well defined means of assessing dental crowding. In previous literature conflicting evidence exists regarding the part played by tooth size and arch dimension in causing dental crowding. The objective of present study were to; examine the relationship between tooth size and arch dimension in crowded and non crowded arches, and to find out the major contributing factor in dental crowding of each. Eighty patients, 20 males and 20 female in crowded and non crowded group comprising of 40 patients each, with an age range of 14-18 years, reporting to outdoor of orthodontic department, was selected. All subject met the following criteria; 1] No cast with missing or impacted teeth. 2] No history of previous orthodontic treatment, 3] No cast showing any dental anomalies. The study included on clinical examination, crowding was assessed clinically in crowded arches with gross mal-alignment of teeth and non crowded arches showing no or mild crowding. Arch dimensions was measured from left to right First permanent molar at the inter section point of lingual groove with gingival margin on the dental cast and tooth size measurement were taken from the anatomatical contact points with the help of Vernier caliper. Similarly inter premolar width was measured. Inter canine width was recorded from canine tips. Arch length was taken with the help of Brass wire directly from the dental cast following the curve of occlusion from mesial marginal ridge of first permanent molar. Data was analyzed by using SPSS [version 10] in personal computer. Paired and independent t-test was used to find out the group differences in crowded and non crowded arches. Results showed that overall no significant differences [p>0.05] were found in tooth size between the non crowded and crowded arches, regardless of whether the tooth size was compared individually or collectively. Statistically significant differences [p<0.05] were observed when arch dimension of crowded and non crowded groups were measured particularly lingual arch width at the inter molar and inter premolar area. No statistically differences were found between the males and females comparison except that female showed smaller values as compared to males in every aspect of measurement
