Aims: Auriculotherapy is a therapeutic method of traditional Chinese Medicine in which a stimulus is exerted on the ear and activates energy channels throughout the body, helping to control anxiety, stress, pain, inflammation, illnesses chronic, and possibly can be used in patient with Arnold Chiari Malformation type II who have painful symptoms that are difficult to resolve. Thus, the aim of this article is to present a case in a patient with Chiari Malformation II where auriculotherapy and effect of laser therapy were performed, to relieve symptoms of agitation, anxiety and healing of self-mutilation injuries.
Case Report: Data from medical records were used to collect medical and dental history, complaints and treatments performed.
Purpose: To compare the stress distribution through photoelasticity, microhardness and roughness of intact crowns of primary molars (CC) and the preformed crowns of stainless steel (SSC) and zirconia (ZC) used in dental restorations in pediatric dentistry.
Methods: Six healthy primary molars were selected. For the photoelastic models, the teeth were fixed in photoelastic resin.
In this study, we evaluated the knowledge, attitudes, and psychosocial impacts among Brazilian pediatric dentists during the COVID-19 pandemic. A cross-sectional study with primary data collection was carried out using an online structured questionnaire. Data were submitted to descriptive analysis by using absolute and relative frequencies.

Sixty primary teeth were divided according to the beverages and a control group (artificial saliva). Immersion cycles were carried out under agitation (five minutes three times a day over 60 days).
We report a 7-year-old boy who presented with a nodule on the upper lip. A previous clinical history of mechanical trauma in the lesional area had been noted. After surgical excision, microscopy revealed fibrocollagenous fascicles associated with neurovascular bundles and skeletal striated muscle fibers in diffuse subepithelial distribution, suggesting rhabdomyomatous mesenchymal hamartoma.

The most common dental anomalies are oligodontia and anodontia but taurodontism has also been described. These patients present a decrease of alveolar bone volume and alveolar ridge tapering due to congenitally missing teeth.

The characteristics associated with LADD are mainly related with hypoplasia or aplasia of lacrimal and salivary ducts, low cup-shaped ears, sensorineural or conductive hearing loss, abnormalities of teeth, and anomalies of the hands and feet. The purpose of this paper is to describe a 13-year-old female patient with a history of a blocked tear duct, mild hearing loss, congenitally missing teeth, tauro- dontism, and malformation of the fingers who was referred for a dental evaluation.

Healthy fresh human primary and permanent molars (n = 10) were selected, The buccal surfaces facing upwards were stabilized in an acrylic plate, flattened, polished, and submitted to the µ-EDXRF, FT-Raman, and HD analysis. The results of the analysis were subjected to ANOVAs and Mann-Whitney U/Student's t multiple comparisons tests.

Materials And Methods: Seventeen sound third molar crowns were embedded in acrylic resin, and the mesial-distal enamel surfaces were flattened. The enamel sites were irradiated with a 2.
In several countries the most common cause of death in young people is cancer. Patients with head and neck cancer often have complications after cancer treatment. Radiation therapy can cause oral trismus, which is related to high doses of radiation.

The recessive form of EB presents the greatest oral alterations including repeated blistering and scar formation leading to limited oral opening, ankyloglossia, tongue denudation, microstomia, vestibule obliteration and predisposition to oral carcinoma. Routine dental care may cause bullae formation on the lips and oral mucosa.

Seventy-five primary incisors were divided for microhardness test (n=45) or scanning electron microscopy (SEM) analysis (n=30). The specimens were randomly assigned to 3 groups: 1 - artificial saliva (control); 2 - cola-type soft drink; and 3 - soy-based orange juice.

Qualitative and quantitative comparisons of the dental enamel were done.
West syndrome (WS) is a rare, severe form of epilepsy that typically manifests early in infancy. It is considered a malignant condition that combines episodes of spasms that occur in clusters (infantile spasm), hypsarrhythmia on the electroencephalogram, and neuropsychomotor delay. Although WS has been widely investigated from a medical standpoint, few reports have focused on the oral findings in patients with this syndrome.
