A Comparison of manufacturer tolerance of different performed orthodontic arch wires
No full textObjective: To measure manufacturer tolerance of preformed rectangular orthodontic arch wires in terms of cross sectional, vertical and transverse dimensions.
Materials and Methods: One hundred and twenty preformed archwires were selected from six various brands in both stainless steel and nickel titanium. Transverse dimensions were measured at both intercanine and intermolar area by photocopying the wires and intra brand comparison was done by using portable USB microscope. Cross sectional dimensions were measured with micrometer while vertical discrepancy was measured at anterior and intermolar region with leaf gauges. One sample t test used to evaluate intra-brand tolerance in wires.
Results: Db orthodontics stainless steel wires were the most oversized while Dentaurum nickel titanium wires were the most undersized in terms of wires height. In terms of wire width, Ortho Organizers stainless steel wires were most oversized while Db orthodontics nickel titanium wires were the most under sized wires. Considering transverse dimension, intercanine width within a brand was found uniform while 3M stainless steel and Dentaurum nickel titanium wires showed statistically significant discrepancy at intermolar area in intrabrand comparison. Statistically significant vertical discrepancy at intermolar region was found in four out of six brands of stainless steel wires and only one brand of nickel titanium wires.
Conclusion: Preformed orthodontic wires can be oversized or undersized in cross sectional dimensions with vertical discrepancy mostly present in stainless steel wires. Manufacturer makes uniform intercanine width but intermolar width is usually expanded from the intended arch form

Alignmen of Teeth by Driftodontics: A Case Report
No full textPhysiological tooth movement or driftodontics of teeth in extraction space decrease the amount of mechanotherapy during clinical orthodontics. This is especially helpful in young patients with anterior mandibular crowding. We present a case of 13-year-old girl with severe crowding in the lower arch and moderate crowding in the upper arch. Anterior crowding in mandibular arch was relieved by driftodontics after extraction of first premolars and placement of lingual arch to prevent molar mesialization
Assessment of Body Composition Distribution Based on Cardiometabolic Factors and Physical Activity in HUNT4 Population
No full textObjektiv:
Målet med denne tverrsnittsstudien var å undersøke fordelingen av ulike kroppssammensetningsmål i forhold til kardiometabolske faktorer og nivåer av fysisk aktivitet ved bruk av objektivt målte kroppssammensetningsdata fra det befolkningsbaserte HUNT4-prosjektet.
Metoder:
Vi brukte observasjonsdata fra HUNT4 Trøndelag Helseundersøkelse 2017–2019. Helseundersøkelsen HUNT4 Nord-Trøndelag besto av 56 041 norske personer som var 19 år eller eldre. InBody 770 bioimpedansskanneren ble brukt til å vurdere kroppssammensetningsmålinger i denne studien, inkludert kroppsmasseindeks, kroppsfettmasse, kroppsfettprosent og fettfri masse. Selvrapporterte spørreskjemaer ble brukt for å evaluere fysisk aktivitet og kardiometabolske sykdommer. For å bestemme gjennomsnittlig og gjennomsnittlig forskjell med 95 % CI for målinger av kroppssammensetning basert på kardiometabolske variabler og nivåer av fysisk aktivitet, ble lineær regresjonsanalyse brukt.
Resultater:
Kroppssammensetningsindikatorer, inkludert kroppsmasseindeks, prosent kroppsfett og kroppsfettmasse, var høyere hos deltakere som rapporterte kardiovaskulær sykdom (CVD), hypertensjon, diabetes og de som tok blodtrykksmedisiner sammenlignet med de uten disse tilstandene. Samtidig var deres fettfrie masseverdier lavere. I tillegg viser funnene at lavt fysisk aktivitetsnivå blant de som rapporterte kardiometabolske lidelser var assosiert med mindre gunstig kroppssammensetning, mens høyere nivåer av fysisk aktivitet var knyttet til bedre kroppssammensetningsmålinger.
Konklusjon:
Den nåværende studien etablerer populasjonsbaserte referanseverdier for kroppssammensetning basert på kardiometabole sykdommer og fysisk aktivitetsnivå. Slike data kan være fordelaktige for å gjenkjenne negative kroppssammensetningsverdier og etablere fokuserte håndteringsstrategier for individer med kardiometabolske lidelser.Aims:
The objective of this cross-sectional study was to examine the distribution of different body composition metrics in connection to cardiometabolic factors and levels of physical activity by using objectively measured body composition data from the population-based HUNT4 project.
Methods:
We used observational data from the 2017–2019 HUNT4 Trøndelag Health Study. The HUNT4 Nord-Trøndelag Health Study consisted of 56,041 Norwegian individuals who were 19 years of age or older. The InBody 770 bioimpedance scanner was utilized to assess body composition metrics in this study, including body mass index, body fat mass, body fat percentage, and fat-free mass. Self-reported questionnaires were used to evaluate physical activity and cardiometabolic diseases. To determine the mean and mean differences with 95% CIs for body composition measurements based on cardiometabolic variables and levels of physical activity, linear regression analysis was used.
Results:
Body composition indicators, including body mass index, percent body fat, and body fat mass, were higher in participants who reported cardiovascular disease (CVD), hypertension, diabetes, and those taking blood pressure medication compared to those without these conditions. At the same time, their fat-free mass values were lower. Additionally, the findings demonstrate that low physical activity levels among those who reported cardiometabolic disorders were associated with less favorable body composition, while greater levels of physical activity were linked to better body composition measurements.
Conclusion:
The current study establishes population-based reference values for body composition based on cardiometabolic diseases and physical activity levels. Such data could be beneficial for recognizing negative body composition values and establishing focused management strategies for individuals with cardiometabolic disorders
A Comparison of Lubricated and Non-lubricated Elastomeric Separators
No full textObjective: To compare lubricated and non-lubricated elastomeric separators in terms of time taken for insertion between contact points, type of contact points encountered and force applied during insertion.
Place of Study: Institute of Dentistry, CMH Lahore Medical College, Lahore
Methodology: Forty patients willing to undergo fixed orthodontic treatment were selected for the study. Elastomeric separators divided into two groups were inserted in molar region. In group A, non-lubricated separators were passed between 106 contact point while in group B, Vaseline lubricated elastics were passed between equal number of contact points. Time taken for insertion of separators, type of force required and type of contact points encountered was noticed. Descriptive statistics were used to evaluate mean and standard deviation of time and age distribution of sample while frequency of force and contact points were also noted. One Way ANOVA was used to analyze time difference and force application across four different contact points in both Vaseline and non-Vaseline group.
Results: The mean time taken for Vaseline lubricated group was 4.76 seconds while in non-lubricated elastics, it was 7.33 seconds. Non Vaseline group encountered 13 % more tight contact points than Vaseline group. One-way ANOVA revealed that there was statistically significant difference between lubricated and non-lubricated separators in terms of time taken for insertion, force required for insertion and types of contact points encountered.
Conclusion: Vaseline lubricated separators take less time to insert and also lesser force was required to insert them. More time and force is required if the contact points are tight as compared to open contact points
A STUDY ON THE EFFECTS OF INTRAUTERINE INSEMINATION OF ATMOSPHERIC TEMPRETURE
No full textObjective: To find out the effects of temperature on the outcome of intrauterine insemination (IUI).
Methodology: This study was conducted at Jinnah Hospital Lahore and the duration of this study was from November 2019 to September 2020. The base and the scope of temperature wide open to the harsh element’s climate were 3°C to 17°C and 13°C to 27°C and in the sweltering, climate was 25°C to 32°Cand 43°C to 50°C separately. The chose fruitless couples were male factor fruitlessness with anomalous parameters of semen, sexual brokenness and strange post coital test and ovulatory factor and unexplained barrenness. Pregnancy was affirmed by serum Beta HCG.
Results: Among 200 cycles exposed to the harsh elements climate, 22 patients got pregnant, (PR/cycle =6.53%) and among 194 cycles in the sweltering climate 16 patients were pregnant, (PR/cycle =4.10%) (P=0.23) There was no noteworthy connection amongst temperature and the result of IUI.
Conclusion: The finding of examination demonstrates that the result of IUI is not affected by temperature and climate is if no significance for IUI.
