The average amount of resorption per root of examined maxillary incisors or anterior teeth is < 1.5 mm during comprehensive orthodontic treatment. About 5% of adults and 2% of adolescents are likely to have at least one tooth with resorption of more than 5 mm during active treatment. Although resorption stops once the active appliances are removed, fortunately, truly severe resorption that threatens the longevity of the tooth or forces a halt to treatment is rare. The fact is, however that orthodontic tooth movement does directly cause irreversible resorption of the root. As the movers of the teeth, it is incumbent for us to know as much as possible about the causes, effects and prevention of this phenomenon.

Aim To compare the quality of obturation using WVC (warm vertical compaction), CLC (cold lateral compaction), injectable (iFill), and Thermafil (GuttaCore) techniques, along with hydraulic condensation of bioceramic (BC) sealer, and evaluating the percentage of gutta-percha (GP), sealer, and voids in simulated internal resorptive lesions, using an advanced stereomicroscope with ImageJ software (National Institutes of Health, Bethesda, MD, USA). Methods and material In this study, 40 freshly extracted maxillary incisors were collected, and endodontic instrumentation was done to working length using hand K-files. Simulated internal resorption cavities were created in the middle-apical third of the roots after horizontal sectioning and were re-cemented.

Background: Hypophosphatasia (HPP) is an inherited disease caused by low activity of tissue-nonspecific alkaline phosphatase. Dental characteristics include premature loss of primary teeth, enlarged pulp chambers, and enamel hypoplasia. Although enzyme replacement therapy with asfotase alfa was approved in 2015, there are few reports about the dental outcomes of this treatment.

Background: The advances in technology have enabled the customization of appliances including mini-screw-assisted rapid palatal expansion (MARPE) appliances for skeletal expansion in young adult patients. The study assessed the short-term effects of customized MARPE appliances on the hard tissues, soft tissues, and airway volume over a period of 6 months.
Methods: A total of 15 patients in the age range of 15 to 25 years were treated for transverse maxillary deficiency using a three-dimensional (3D) printed customized MARPE appliance.

Orthodontic treatment aims to correct malocclusions and ensure the overall health and stability of the periodontium. The relationship between orthodontic therapy and periodontal health is intricate and multifaceted, and a comprehensive approach is often required to achieve optimal outcomes. Firstly, this article delves into the impact of orthodontic mechanics on periodontal tissues, emphasizing the importance of minimizing iatrogenic effects such as root resorption and gingival recession.

Objective: Miniscrews are commonly utilized as temporary anchorage devices (TADs) in cases of maxillary protrusion and premolar extraction. This study aimed to investigate the effects and potential side effects of two conventional miniscrew configurations on the maxillary incisors.
Methods: Eighty-two adult patients with maxillary dentoalveolar protrusion who had undergone bilateral first premolar extraction were retrospectively divided into three groups: non-TAD, two posterior miniscrews only (P-TADs), and two anterior and two posterior miniscrews combined (AP-TADs).
