The aim of this study was to compare in vitro the micro hardness of enamel exposed to the erosive effects of three pre-workout drinks. Forty blocks (4mmx4mm) of bovine enamel were randomly selected and divided among the following pre-workout drinks (n=10): G1: Universal Shock Therapy®, G2: 1.M.R Vortex™, G3: Jack3Dmicro™, G4: Control (distilled water). The enamel microhardness was evaluated before (T1) and after (T2) the in vitro erosive test (5 min/3 times/5 days) using a Vickers digital microduremeter (load 100g/penetration 15s). The data was analyzed using descriptive statistics (mean, ±sd) and for comparison testing, using the Kruskall Wallis test and the t Student test (p≤ 0.05). All groups showed a reduction in micro hardness after the erosive test (p =0.001).1.M.R Vortex™ drink showed a large decrease in micro hardness (%SMH:34,92%). Pre-workout drinks significantly decreased the superficial micro hardness of enamel

Tooth Size Discrepancy (TSD) forms part of the initial diagnosis and is considered when formulating a treatment plan for the individual patient. The present research aimed at determining the extent and prevalence in a representative orthodontic population in Libya, to determine the prevalence of tooth size discrepancies (TSDs) in orthodontic population among different malocclusion groups.

In this in-vitro study, teeth were imaged using photoacoustic tomography (PAT), cone-beam computed tomography (CBCT), and micro-computed tomography (µ-CT). The study had the following aims: to identify the best wavelength for imaging teeth when using PAT, to determine the accuracy of the three imaging methods, and to determine whether PAT images of teeth can achieve acceptable reconstruction quality.

The wind instruments are the musical instruments most likely to cause oral lesions, because their use involves the involvement of anatomical structures of the oral and perioral cavity. The purpose of this literature review was to assess the impact of wind instruments on the oral condition of musicians. Scientific articles indexed in the databases Pubmed, Lilacs, Scielo, Cochrane and also in Google Scholar were evaluated. Publications from 1935 to 2020 were included and the following descriptors were applied: wind musicians and oral conditions, wind musicians and periodontal conditions, wind musicians and occlusal disorders.

Foreign body ingestion is a common occurrence among children and adults with certain risk factors including advanced age and psychiatric diseases. However, in clinical practice we encounter healthy adults who are diagnosed with unintentional foreign body ingestion and are not able to remember it. These cases may be complicated by gastrointestinal perforations in case of ingesting sharp objects. Only clinical suspicion would help clinicians for prompt diagnosis in such cases.

This study aimed to determine whether a relationship exists between gingival stimulation and the levels of leptin, ghrelin, insulin and glucose, which are important regulators of energy homeostasis. Blood samples for ghrelin, leptin, glucose and insulin were taken from 15 male volunteers (mean age 25.5±2.3 years; mean body mass index 24.4±2.79 kg/m2), who did not brush their teeth for one day, after a 12 h-long overnight fasting and before standard breakfast (0 min) and thereafter at 30, 60, 120 and 180 min after breakfast. After toothbrushing after dinner and after a 12 h-long overnight fasting, blood samples were taken again before standard breakfast (0 min) and then after at the same time points following tooth brushing.A significant reduction was found in the leptin levels measured at 0, 30, 60, 120 and 180 min after tooth brushing (p < 0.005). The ghrelin levels also declined at these time points but were significant at 0, 30 and 120 min (p < 0.05). Despite the reduced insulin levels at 120 and 180 min after tooth brushing (p < 0.05), no significant change was observed in the glucose levels.

An ectopic tooth in a nasal cavity is a rare phenomenon. In most cases, no etiological explanation of teeth in that location has been suggested or found. We report the case of a 26-year-old man, who discovered, 5 years ago, an induration inside his right nasal pit, which caused an unilateral nasal obstruction, without rhinorrhea, with epistaxis, revealing an ectopic in intra-nasal tooth.

This study aimed to investigate the existence of the golden proportion between the widths of the maxillary anterior teeth in individuals with an aesthetic smile. This study was conducted on 120 subjects (60 women and 60 men), with ages ranging from 18 to 25 years. Those subjects whose natural smile did not show any visual tension with regards to the study and their own criteria were selected as having aesthetic smile. An image measurement program was used to measure the apparent mesio-distal widths of six maxillary anterior teeth on the scanned photographs of these subjects. Individual measurements of each maxillary anterior tooth were taken and the golden proportion was compared. The existence of the golden proportion was investigated in the width ratios of maxillary anterior teeth.

Subcutaneous emphysema and pneumomediastinum following extraction of mandibular third molars are rare. These complications are caused by forceful injection of air into the connective tissue. The symptoms may vary depending on the quantity of air, its location and the presence or absence of infection. In most cases, the subcutaneous emphysema will begin to disappear in 3-5 days. This report presents a case of subcutaneous emphysema and pneumomediastinum after wisdom extraction.

Cellulites of dental origin are extensive polymicrobial infections of the face and neck cell-adipose tissues. Management of infections of this nature presents significant challenges. The key to this is the identification of the causative organisms and determination of their susceptibility to antibiotics.

Supernumerary ectopic teeth are not uncommon; they present in abnormal location in oral cavity or may occupy a more unusual position, such as Maxillary Antrum. They are often diagnosed as incidental finding on routine Radiography; however, few may be symptomatic. Treatment options vary from endoscopic removal to conventional extraction by dental surgeon.
