OBJECTIVE: To determine Oral Health Related Quality of Life (OHRQoL) in patients receiving fixed orthodontic treatment METHODS: This study was conducted at department of Orthodontics, Khyber College of Dentistry, Peshawar from 24th March 2022 to 30th June 2022. One hundred and seventy-five patients, undergoing fixed orthodontic therapy for at least three months were included in the study. Patients with oral diseases that directly or indirectly affect OHRQoL, any previous orthodontic treatment, cognitive impairment and craniofacial anomalies were excluded. The OHRQoL was recorded using Oral Health Impact Profile-14 (OHIP-14) questionnaire. Independent samples t-test was used to examine the relationship between age and gender with total OHIP-14 score. Comparison of OHIP-14 score among socioeconomic levels and educational level was done using one way ANOVA. RESULTS: The mean age of the participants was 23.13±5.25 years, OHIP-14 score was 29.48±7.36 and 56% (n=98) were females. No significant difference was found between gender, age of the participants, socioeconomic status (SES) and the OHIP-14 score (p=0.05). Highest mean OHIP-14 score was found in 'higher educational level' followed by intermediate then secondary school and least in primary education level and it was very highly statistically significant (ANOVA test, p<0.001). Participants had negative effect on pronouncing words (47%), physical pain (88%), and psychological discomfort and social disability (94%). CONCLUSION: Fixed orthodontic appliances significantly impact participants' QoL, with educational level varying, while gender, age, and SES showed no significant effect on OHIP-14 scores. Functional limitations, physical pain, psychological discomfort, and social challenges were prominent domains affected by orthodontic treatment. [ABSTRACT FROM AUTHOR]

Objective: To determine the relationship of palatally impacted canine with skeletal and dental anomalies in orthodontic patients. Material and Methods: This retrospective study involved a total of 94 participants, with 47 cases with PICs and 47 controls. The inclusion criteria were high-quality orthodontic radiographs includ-ing lateral cephalograms and panoramic radiographs and dental casts. Exclusion criteria involved patients with incomplete orthodontic records, medical pathologies, syndromes, history of head and neck radiotherapy or surgery, and previous orthodontic treatment. The dental anomalies investigat-ed in this study focused on upper lateral incisor anomalies, while skeletal anomalies included sella turcica bridging and ponticulus posticus. The extent of sella turcica bridging and ponticulus posticus was evaluated using a standardized scoring system developed by Leonardi et al. Association was determined using the Chi-square test. Results: The mean age of the participants in this study was 27.30±7.14 years. Among the cases, there were 28 females (59.57%), while among the controls, there were 27 females (57.45%). Significant associations were found between sella turcica bridging and maxillary impacted canine (p = 0.005), indicating a strong relationship. Additionally, there was a marginally significant association between ponticulus posticus and maxillary impacted canine (p = 0.042), suggesting a weaker but still notewor-thy association. On the other hand, the association between anomalous lateral incisors and palatally impacted canine did not reach statistical significance. Conclusion: There is a significant association of the bridging of sella turcica and ponticulus posticus with palatal canine impaction. However, no statistical association was found between anomalous lateral incisor and palatal impaction of canine. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study was to compare the palatal vault depth on the digital scanned models versus plaster models. Methodology: In this Cross-sectional comparative study, thirty plaster models were selected for recording measurements. Palatal depth was recorded manually on plaster models with digital calipers and the same measurements were repeated on their scanned digital versions obtained with Carestream Scan Flow, using distance measuring tool. Two examiners independently recorded the measurements. Results: The difference between the manual and digital methods was statistically insignificant (p=.074), for palatal vault depth measurement at the molar region. Although statistically significant (p=.001), palatal vault depth difference between the two methods, at the inter canine area was of small magnitude to have any clinical significance. Inter observer and intra observer reliability was reason-ably good (r>.75). The gender wise differences between the all the measurements were insignificant. For palatal vault depth on digital models at the intermolar region the difference was insignificant (p=.83) and similarly on plaster models, palatal vault depth at the intermolar region was also sta-tistically insignificant (p=.92). Conclusion: The reliability and reproducibility of digital models was good enough to provide a satisfactory alternate for plaster models in recording measurements like palatal vault depth in clinical settings.

To determine the correlation between the width of permanent maxillary anterior teeth and the horizontal facial dimensions. This cross-sectional descriptive study included 82 participants. The inclusion criteria were adult patients of both genders, with complete set and good alignment of maxil-lary anterior teeth. Data were collected for age, gender, facial dimensions, and dental widths. Vernier calliper was used to measure the mesiodistal width [MDW] of the maxillary anterior teeth and facial dimensions (inter-pupillary distance [IPD], inter-canthal distance [ICD], and bi-zygomatic width [BZW]). The student t-test was used to compare facial and dental measurements between genders, while the Pearson correlation test was used to determine the relationship between dental and facial dimensions. The mean age of the participants was 24.54±4.94 years, with 44 (53.66%) of them being females. Statistically, dental and facial dimensions were larger in males than in females (p<0.05). Th re was a moderately positive and significant correlation between the central incisor and IPD (r=0.54, p<0.001), as well as the lateral incisor with IPD (r=0.4, p<0.001), and the canine with IPD (r=0.54, p<0.001). The correlation between the central incisor and ICD was high, positive, and sig-nificant (r=0.71, p<0.001), and similar results were found for the canine with IPD (r=0.71, p<0.001). The correlation between dental widths and BZW was moderately positive and statistically significant. Facial parameters can be used to predict the maxillary anterior tooth sizes.

Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of the study was to evaluate the degree of correlation between a dental parameter (overjet) and a skeletal (ANB) angle. Eighty nine patients fulfilled the inclusion criteria for the study ( 22 males and 69 females, aged 12- 35). Overjet was measured on casts with a standard ruler. Lateral cephalograph was taken to measure the ANB angle. The correlation analysis of overjet with ANB angle in the three malocclusion classes showed, that there was a weak correlation of overjet with ANB angle in all three groups of malocclusion with "r" value of 0.257 whereas P value was statistical insignificance (P-value > 0.05). This study concluded that overjet is not a good predictor for sagittal skeletal relationship and therefore could not be used for better assessment of sagittal jaw relation which is critical in orthodontic diagnosis and treatment planning.

Esthetic features are different from one race to another, and this should be considered during the treatment planning. The great variance in soft tissue drape of the human face complicates accurate assessment. The nose--lip--chin relationships are exceedingly important in determining the facial esthetics. One important soft tissue parameter in orthodontic diagnosis is the nasolabial angle. The purpose of this study was to establish norms for nasolabial angle in the local population. Normative data for the nasolabial angle was produced from a sample of 50 (25 male and 25 female) adults (18-25 yrs) with well-balanced faces. Mean and standard deviation values from this pooled sample demonstrated a nasolabial angle of 105.8° ± 3.95°. No statistically significant difference was demonstrated between the values for men and women in this study, but men did have a slightly larger nasolabial angle. [ABSTRACT FROM AUTHOR]
