Background Many public health professionals have expressed concern that regular participation in recreational settings with high noise levels might induce hearing loss. This study measures the noise levels in a baseball stadium and analyzes baseball fans' attitude of effect of recreational noise exposure on their hearing. Methods In the baseball stadium, noise levels from the beginning to the end of four games were measured in four seating sections, the red, blue, navy, and outfield sections using a sound level meter. EHT1864 For the survey sample, 344 randomly selected participants who visited the stadium and/or were baseball fans completed a 16-question survey on their noise exposure during the game and on the potential risk of hearing loss. Results The LAeq average of the 16 measures produced 91.7 dBA, showing a significantly high noise level in the red and navy sections. As a function of frequency by LZeq analysis, the noise levels of low frequencies between 0.05 and 1 kHz were significantly higher than other frequencies except for the outfield section, but the levels abruptly decreased above 1 kHz. Despite the very high noise levels, 70% of the respondents preferred sitting in either the red or the navy section to be closer to the cheerleaders and to obtain a good view. Most respondents reported that they did not consider wearing earplugs, and one-third experienced hearing muffled speech after the game. Notably, they agreed that an information announcement regarding loud noise and hearing protection was needed at the stadium. Conclusions We conclude that the noise levels in baseball stadiums are high enough to cause hearing damage and/or tinnitus later when applying a rule of 85 dB LAeq for 8 hours with a 3-dB exchange rate. We expect these results to improve public education regarding safe noise exposure during popular sports activities.Dandy-Walker syndrome (DWS) is a rare congenital cystic malformation of the posterior cranial fossa. Patients show signs and symptoms of complex clinical manifestations, ranging from cranial nerve and cerebellar dysfunctions to extracranial abnormalities, which may pose challenges in dental management. This article represents a rare case of a 12-year-old girl with DWS along with the involvement of the oral cavity.Oral squamous papillomas are benign proliferating lesions induced by human papillomavirus. These lesions are painless and slowly-growing masses. As an oral lesion, it raises concern because of its clinical appearance. These lesions commonly occur between age 30 and 50 years, and sometimes can occur before the age of 10 years. Oral squamous papilloma accounts for 8% of all oral tumors in children. Common site predilection for the lesion is the tongue and palate and may occur on any other surface of the oral cavity such as the uvula and vermilion of the lip. Here, we are presenting a case of squamous papilloma on the palate in a 9-year-old child.One of the most common clinical challenges encountered with facemask therapy for early correction of skeletal Class III malocclusions is the delivery of appropriate direction of force for effecting the pure translation of maxilla. This technical note describes a novel method involving the use of Begg's auxiliary for achieving efficient and predictable delivery of protraction forces. With this modified assembly, effective vector control for facemask can be achieved without the need to remove the bonded Hyrax assembly. This chairside modification is an effective and invaluable method for predictable force delivery in facemask therapy.Periostitis ossificans (PO) is a type of osteomyelitis stemming from an odontogenic infection, generally found in children and adolescents, and often leads to the loss of the involved tooth. This case presents a less invasive alternative for the treatment of PO. A 10-year-old patient presented with an asymmetrical increase in the left side of the mandible. Tooth 36 exhibited pulp necrosis and incomplete root
