Oral Health Assessment of Children with Autism Spectrum Disorder in Special Schools.

Background: Sensory over-responsivity is an important factor influencing the ability of children with an autism spectrum disorder to receive proper oral care. Dental care remains the most prevalent, unmet health care need for children with special health care needs.

Three-dimensional semi-automated volumetric assessment of the pulp space of teeth following regenerative dental procedures.

The volumetric change that occurs in the pulp space over time represents a critical measure when it comes to determining the secondary outcomes of regenerative endodontic procedures (REPs). However, to date, only a few studies have investigated the accuracy of the available domain-specialized medical imaging tools with regard to three-dimensional (3D) volumetric assessment. This study sought to compare the accuracy of two different artificial intelligence-based medical imaging programs namely OsiriX MD (v 9.

Ultrasonography as a diagnostic aid for a neonate with gingival swelling in a COVID-19 neonatal intensive care unit.

COVID-19 pandemic has impacted all the aspects of life and has emerged as the biggest challenge to the health-care sector. Dental fraternity has also taken its significant impact since the transmission of disease is primarily through aerosol droplets. Management of infants with orofacial anomalies such as natal and neonatal teeth born to COVID-19-positive mothers is another challenge due to unavailability of dental facilities in the isolation wards.

Three-dimensional qualitative and quantitative analyses of the effect of periradicular lesions on the outcome of regenerative endodontic procedures: A prospective clinical study.

Objectives: Qualitative and quantitative evaluation of the outcomes of regenerative endodontic procedure (REP) on human immature necrotic teeth with apical periodontitis using cone-beam computed tomography (CBCT) MATERIALS AND METHODS: Immature permanent teeth (n = 50) with necrotic pulp and periradicular pathosis were treated with a cell-homing concept-based REP. Following the procedure, a limited field-of-view CBCT scan was obtained. At each recall session (6, 12, 18 months), clinical tests were performed, and a digital periapical radiograph was taken.

Dental management of a child with Wiskott Aldrich syndrome prior to bone marrow transplant: A case report.

Aim: Orodental manifestations are commonly presented in Wiskott Aldrich Syndrome (WAS). The purpose of this paper is to report a case of dental management of a 5-year-old male child with WAS before Hematopoietic Stem Cell Transplantation (HSCT). Such patients are more prone to infection due to pretransplantation chemotherapy and posttransplantation immunosuppression; thus, it becomes imperative to eliminate all potential sources of infection before transplantation.

Effect of CO Laser and 1.23% Acidulated Phosphate Fluoride on Acid Resistance and Fluoride Uptake of Human Tooth Enamel: An Assessment.

Aim: To evaluate the effectiveness of CO laser treatment before applying 1.23% acidulated phosphate fluoride (APF), through topically applied 1.23% APF solution, and after applying 1.

Scanning electron microscopic observation of primary tooth dentin following final irrigation with 95% ethanol: An in vitro study.

Background: The beneficial effects of irrigants during endodontic treatment are well known; however, it may have some deleterious effects on the internal root canal wall, thereby altering its physical properties.

Aim: The purpose of the study was to assess the effect of 95% ethanol on morphological characteristics of primary root dentin.

Materials And Methods: Biomechanical preparation was done in twenty extracted single-rooted primary anterior teeth using Rotary ProTaper Universal System.

Tamponade effect of resorbable biological barrier in quality of obturation in primary molar.

Aim: Physical properties of obturating materials have a direct effect on the quality of obturation; less viscous material will tend to extrude beyond the apex. We hypothesize that the use of absorbable gelatin sponge (AGS) can prevent the extrusion of these materials. This study aimed to evaluate the quality of obturation in root canals filled with iodoform-calcium hydroxide (Metapex) premixed paste and Metapex with AGS (MAGS) in primary molars.

Prevalence of Traumatic Injuries to Anterior Teeth in 9-14 Year School-going Children in Mumbai, India.

Aim: The aim of this study is to assess the prevalence and causes of traumatic dental injury (TDI) in 9-14 year school-going children in Mumbai, Maharashtra, India.

Materials And Methods: A cross-sectional study consisting of 2,055 primary and secondary school-going children aged between 9 and 14 years, from 20 municipal corporation schools of Mumbai city, was selected through a stratified random sampling technique. Children were examined clinically for any signs of TDI in the permanent anterior teeth in their respective schools by two examiners trained in using WHO criteria for oral and dental examination.

Assessment of Inhibition of Mineral Loss from Human Tooth Enamel by Carbon Dioxide Laser and 1.23% Acidulated Phosphate Fluoride.

Aims And Objectives: The efficacy of carbon dioxide (CO) laser irradiation combined with fluoride in inhibiting enamel demineralization has been demonstrated by several laboratory investigations. However, there are very few reports about the or caries preventive effect of CO laser combined with topical fluoride on dental enamel. Hence, an study was designed and carried out to assess inhibition of mineral loss from human tooth enamel by CO laser and 1.

Immunohistochemical characterization of stem cell and differentiation markers of the dental pulp of human natal teeth.

Aim: Dental pulp stem cells, which are primarily derived from the pulp tissues of human teeth, have rarely been obtained from natal teeth. This study investigated the stem cell and differentiation markers of the dental pulp of natal teeth using immunohistochemistry.

Materials & Methods: The pulp tissue from extracted natal teeth (n = 2) of a 20-day-old healthy male was examined for immunohistochemical expression of stem cell (Oct-4 and SOX 2) and differentiation markers (Nestin, CD 44, desmin, osteopontin and Ki- 67).

Cone-beam computed tomographic and histological investigation of regenerative endodontic procedure in an immature mandibular second premolar with chronic apical abscess.

Aim: The aim of the present study was to investigate the tissue generated after regenerative endodontic procedure (REP) in the root canal space of an immature mandibular second premolar with pulp necrosis and chronic apical abscess using cone-beam computed tomographic (CBCT) and histological methods.

Methods: REP was performed in an immature mandibular second premolar. At the 3-year follow up, CBCT scans were taken to evaluate the outcome of treatment.

Comparative evaluation of the clonogenic capacity of periodontal ligament fibroblasts in Hank's balanced salt solution and egg albumen: An in vitro study.

Background/aim: The type of storage media for short-term storage of an avulsed tooth is a critical determinant for the success of tooth replantation. If immediate replantation of an avulsed tooth is not possible, it is advised to store the tooth in a suitable storage medium. The viability and clonogenicity of periodontal ligament fibroblasts (PDLF) determines the success of replantation of an avulsed tooth.

Gingival Enlargement Caused by Vitamin C Deficiency (Scurvy) in a Boy.

Localized gingival enlargement associated with vitamin C deficiency (scurvy) is rarely encountered in the modern era. The purpose of this paper is to report a case of extensive inflammatory gingival enlargement in the mandibular anterior region associated with vitamin C deficiency in a 10 year-old boy. There was a significant improvement of the gingival enlargement seven days after starting oral vitamin C supplementation.

An unusual association of extraoral sinus tract with unerupted permanent tooth.

Cases have been reported in the literature in which extraoral sinus tracts of dental origin have been diagnosed and successfully treated. Similarly, the presence of an intracoronal radiolucency in unerupted permanent teeth has been found in the dental literature. The association of one with the other, however, is a rare occurrence.

Management of nasally erupting deciduous canine in operated cleft lip and alveolus patient.

Nasally erupting tooth is a rare finding seen associated with cleft lip and alveolus. It may be diagnosed as a result of symptoms such as difficulty in breathing, pain on sneezing or blowing the nose or may remain asymptomatic. A case of a 4 year old male child operated for bilateral cleft lip and alveolus with unilateral right sided nasally erupting deciduous canine is presented here.
