    Do the various interceptive interventions improve the position of palatally displaced permanent canines? A meta-analysis
    (2021) Habib, Ahlam
    Background: Extraction of maxillary primary canines (Cs) and other interceptive interventions in the mixed dentition have been suggested to increase the rate of normal eruption of palatally displaced permanent canines (PDCs). However, the information on the overall effect on PDCs position has not been yet summarized in an evidencebased manner. Objective: To assess whether this practice improves the position of PDCs and to investigate the quality of the evidence. Search methods: Unrestricted searches in 8 databases and manual searching of the reference lists in relevant studies were performed up to March 2021 (Medline via PubMed, CENTRAL, Cochrane Database of Systematic Reviews, Scopus, Web of Science, Arab World Research, ClinicalTrials.gov, ProQuest Dissertations and Theses Global). Selection criteria: We looked for data on the positional changes of PDCs (mesial ii inclination, vertical position, canine crown cusp tip to midline) from randomized controlled trials, assessing the various interceptive interventions. Data collection and analysis: Following study retrieval and selection, relevant data were extracted, and the risk of bias was assessed using the Cochrane Risk of Bias 2 Tool. Exploratory synthesis and meta-regression were carried out using the random effects model, and the overall quality of the available evidence was assessed with the Grades of Recommendation, Assessment, Development, and Evaluation approach. Results: Five studies (3 at low risk of bias) were identified, involving 238 individuals, followed for up to 18 months post-intervention with orthopantomograms or cone beam computed tomography. Exploratory data synthesis showed that PDCs’ position improved more in the extraction sites compared to non-extraction. Analysis of the studies at low risk confirmed the above observations (6 and 12 months). Improvements were observed in patients using headgear after extraction of the Cs compared to extraction alone, but not in patients with double extraction of Cs and first molars. The quality of available evidence was rated as moderate at best. Conclusions: Interceptive interventions in the mixed dentition may improve the position of PDCs. However, further studies are warranted in order to determine the clinical significance of the changes.

    Management of mandibular incisors crowding by using passive lower lingual holding arch: a case series and literature review
    (2023) Habib, Ahlam; Ghoneima, Ahmed; Diar-Bakirly, Samira
    Abstract: Mandibular incisor crowding is a frequently encountered problem in daily orthodontic treatment. Success of the treatment greatly depends on the orthodontist’s ability to manage the factors contributing to the existing crowding and implementing the proper interceptive means. The passive lower lingual holding arch (LLHA) helps maintain the position of the permanent first molars after the exfoliation of primary molars and canines. Thus, relieving the mandibular incisor crowding during transitional dentition. Four case reports age ranged from 11–13.5 years old were used to report the effect of using LLHA on mandibular incisor crowding. Little’s Irregularity Index (LII) was used to assess the severity of mandibular incisors crowding as well as to compare the severity of the crowding before and after the use of LLHA. Passive LLHA could be considered the appliance of choice for space maintenance during the mixed dentition. Mandibular incisor crowding was reduced as measured by LII after the use of the passive LLHA over a duration of twenty months.
