  • Current Evidence on the Effect of Pre-Orthodontic Trainer in the Early Treatment of Malocclusion
    IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) e-ISSN: 2279-0853, p-ISSN: 2279-0861.Volume 18, Issue 4 Ser. 17 (April. 2019), PP 22-28 www.iosrjournals.org Current Evidence on the Effect of Pre-orthodontic Trainer in the Early Treatment of Malocclusion Dr. Shreya C. Nagda1, Dr. Uma B. Dixit2 1Post-graduate student, Department of Pedodontics and Preventive Dentistry, DY Patil University – School of Dentistry, Navi Mumbai, India 2Professor and Head,Department of Pedodontics and Preventive Dentistry, DY Patil University – School of Dentistry, Navi Mumbai, India Corresponding Author: Dr. Shreya C. Nagda Abstract:Malocclusion poses a great burden worldwide. Persistent oral habits bring about alteration in the activity of orofacial muscles. Non-nutritive sucking habits are shown to cause anterior open bite and posterior crossbite. Abnormal tongue posture and tongue thrust swallow result in proclination of maxillary anterior teeth and openbite. Mouth breathing causes incompetence of lips, lowered position of tongue and clockwise rotation of the mandible. Early diagnosis and treatment of the orofacial myofunctional disorders render great benefits by minimizing related malocclusion and reducing possibility of relapse after orthodontic treatment. Myofunctional appliances or pre orthodontic trainers are new types of prefabricated removable functional appliances claimed to train the orofacial musculature; thereby correcting malocclusion. This review aimed to search literature for studies and case reports on effectiveness of pre-orthodontic trainers on early correction of developing malocclusion. Current literature renders sufficient evidence that these appliances are successful in treating Class II malocclusions especially those due to mandibular retrusion. Case reports on Class I malocclusion have reported alleviation of anterior crowding, alignment of incisors and correction of deep bite with pre-orthodontic trainers.

  • Establishment of a Dental Effects of Hypophosphatasia Registry Thesis
    Establishment of a Dental Effects of Hypophosphatasia Registry Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Jennifer Laura Winslow, DMD Graduate Program in Dentistry The Ohio State University 2018 Thesis Committee Ann Griffen, DDS, MS, Advisor Sasigarn Bowden, MD Brian Foster, PhD Copyrighted by Jennifer Laura Winslow, D.M.D. 2018 Abstract Purpose: Hypophosphatasia (HPP) is a metabolic disease that affects development of mineralized tissues including the dentition. Early loss of primary teeth is a nearly universal finding, and although problems in the permanent dentition have been reported, findings have not been described in detail. In addition, enzyme replacement therapy is now available, but very little is known about its effects on the dentition. HPP is rare and few dental providers see many cases, so a registry is needed to collect an adequate sample to represent the range of manifestations and the dental effects of enzyme replacement therapy. Devising a way to recruit patients nationally while still meeting the IRB requirements for human subjects research presented multiple challenges. Methods: A way to recruit patients nationally while still meeting the local IRB requirements for human subjects research was devised in collaboration with our Office of Human Research. The solution included pathways for obtaining consent and transferring protected information, and required that the clinician providing the clinical data refer the patient to the study and interact with study personnel only after the patient has given permission. Data forms and a custom database application were developed. Results: The registry is established and has been successfully piloted with 2 participants, and we are now initiating wider recruitment.

  • Common Dental Diseases in Children and Malocclusion
    International Journal of Oral Science www.nature.com/ijos REVIEW ARTICLE Common dental diseases in children and malocclusion Jing Zou1, Mingmei Meng1, Clarice S Law2, Yale Rao3 and Xuedong Zhou1 Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition. This article highlights these diseases and their impacts on malocclusion in sequence. Prevention, treatment, and management of these conditions are also illustrated in order to achieve successful oral health for children and adolescents, even for their adult stage.

  • ENDODONTICS EPT – Stimulates Nerve Endings with Low Current And
    ENDODONTICS . EPT – stimulates nerve endings with low current and high potential difference in voltage; stimulates A delta fibers; no gloves should be used because causes false negative. Results from EPT: ‐chronic pulpitis = higher current than normal ‐acute pulpitis = lower current than normal (acute inflammation mediators lower the pain threshold). ‐hyperemia = lower current than normal, but higher than acute pulpitis. False positives – pus‐filled canal or nervous patient. False negatives – trauma, insulating restoration, or wearing gloves. Trauma causing deep intrusion to a permanent tooth causes pulp necrosis and conventional RCT. SLOB Rule – root farther (buccal) from film will move to same direction cone is directed; lingual surface is always closest to the cone so buccal is always farthest. Referred Pain ‐ Forehead: max. incisors Nasolabial: max. canines and PMs. Temporal: max. 2nd PM. Ear: mand. molars Mentalis: mand. Incisors, canines, and PMs. Hemophilia is NOT a contraindication to endo. Special case – trauma with pulp obliteration but PDL normal; asymptomatic and no EPT response; TX= observe as long as tooth asymptomatic and no PA changes. ACCESS: . mand. molar = trapezoidal, most common tooth for RCT; tipped ML so overprepared ML access; in 40% of cases, may have 2 canals in distal root; . max molar = triangular, highest RCT failure, MB root is most complex of all teeth, because under MB cusp and must be accessed from DL position; M→P line is longest; 59% have MB2; the most common curvature of the palatal root is toward the facial.

  • Early Transverse Treatment Steven D
    Early Transverse Treatment Steven D. Marshall, Karin A. Southard, and Thomas E. Southard Expansion of the maxillary arch to improve transverse inter-arch relationships during the primary or mixed dentition stage is considered early transverse treatment as part of a two-phase treatment protocol. Traditionally, early expansion has been used to correct posterior crossbite. More recently, it has been suggested that early transverse treatment may be beneficial, in the absence of posterior crossbite, to improve arch length deficiency, and to facilitate correction of skeletal class II malocclusions. In this article, the rationale for early transverse treatment in the presence and absence of posterior crossbite is reviewed. Semin Orthod 11:130–139 © 2005 Elsevier Inc.

Methods: Sixteen patients with NCS were diagnosed and treated. The oral and radiographic manifestations were assessed. Results: Four (25%) of 16 patients with NCS were affected by nonmalignant diseases (19% by medication-related osteonecrosis of the jaw and 6% by osteopetrosis); yet 12 (75%) patient conditions were caused by malignant metastasis, either in the mandible (62%) or intracranial invasion (13%). NCS was unilateral in 13 cases and bilateral in three cases. Mandibular pain and masticatory weakness often dominate the clinical features in NCS associated with cancer metastasis.

Treatment of such skeletal deformities requires combination of orthodontic and surgical treatment. The treatment does not change only the bony relations of the facial structures, but soft tissues as well, and by doing so, may alter the patient’s appearance. However, longer treatment times and transitional detriment to the facial profile has led to a new approach called “surgery-first,” which eliminates the presurgical orthodontic phase. After the jaws are repositioned, the orthodontist is then able to properly finish the bite into the best possible relationship. Surgery may also be helpful as an adjunct to orthodontic treatment to enhance the long term results of orthodontic treatment, and to shorten the overall time necessary to complete treatment.
