Obstructive sleep apnea (OSA) is a representative SRBD that involves a significant decrease in or cessation of airflow despite the presence of respiratory effort. While snoring is considered a normal condition, it can cause serious noise disturbance to sleep partners and is considered a predictor of OSA. Snoring and OSA are highly correlated with obesity. SRBDs can lead to cardiovascular disease, hypertension, decreased quality of life, decreased work efficiency, daytime sleepiness, decreased neurocognitive activity, and psychological impairments. In dentistry, research on sleep problems has focused on temporomandibular disorder (TMD)/orofacial pain. The relationship between OSA and TMD/orofacial pain has been reported, but it is not clear whether it is a simple correlation or a causal relationship. Therefore, we aimed to review the causes of SRBDs including snoring and OSA and to review and infer the relationship between these SRBDs and TMD/orofacial pain.

This survey aimed to document the early effect of the pandemic on dental and oral health care workers, their response to combat the COVID-19 outbreak, the evolution of practices, and learn lessons for future health policies in similar situations in the future. Methods A descriptive cross-sectional study was designed and conducted via Google form from 24 June 2020 to 13 July 2020 among Nepal's dental and oral healthcare workers after getting ethical approval from Nepal Health Research Council (Reg 445/2020P / Ref No 2710). The study questionnaire was developed in 4 domains: first, general demographics; second, personal impact; third, professional impact and fourth, the academic impact of COVID-19. In addition, Chi-square test was used to show the relationship between variables. Results Of 133 respondents, 18.8% exposure risk and 14.3% infection rate were found among dental and oral health care workers of Nepal; a higher exposure rate was unmarried (ER, 21.4%), senior residents (ER, 50%), female (ER, 19.6%), 20-29 years (ER, 16%), the Lumbini province (ER, 50%).

All maxillary front teeth were present in all the cases. The distance between the cementoenamel junction (CEJ) and the facial bone crest and the thickness of the labial alveolar bone wall at distances of 1, 3, and 5 mm apical to the facial bone crest were measured.RESULTS: The distance between the CEJ and the facial bone crest ranged from 2.24 mm and 3.08 mm. No significant differences were found between the thickness of the bone wall at 1, 3, and 5 mm apical to the crest. A significant difference was found between the U-shaped arch on one side and the V-shaped and square-shaped arches on the other side. The U-shaped arch and labial bone wall thickness were correlated at the 1-mm distance (F = (8, 276) = 3.24, p = 0.002).

Currently, the longlasting efficacy of the induced immunity from SARSCoV-2 vaccination is largely unknown. Our aim is to study the RDB-IgG response after 1, 4, and 7 months from complete vaccination with BNT6112b2 in an Italian dental team. All 13 dental health care workers (3 men and 10 women) working in a private dental office were enrolled in the frame of scheduled controls for occupational safety. All dental health care workers were aged less than 60 yrs old; the mean age (±DS) was 41.23±9.63 yrs; 2/13 had one medical condition associated with a higher risk of developing severe illness from COVID-19, but none of DHCW were affected with the disease.

Root canal therapy and tooth extraction are the two most common procedures carried out for treatment of toothache. The aim of this study was to find out the most common causes of root canal treated teeth failure and its frequency in different age and gender population. Methodology: Sixty patients with root canal treated teeth who presented for extractions to the minor oral surgery were included in the present study. Names of the patients were replaced by their OPD numbers for the sake of privacy. The subjects were selected regardless from where they had received the treatment, properly examined and their histories recorded after taking written consent. Information was collected using a detailed questionnaire, and questions regarding symptoms/causes for extraction of root canal treated teeth were asked. The data so collected was analysed through SPSS version 26. Results: There were total 60 patients out of which 28 (46.67%) were female and 32 (53.33%) were male. These patients belonged to various age groups out of which 46-55 (26%) age group was the most prevalent followed by 15-25 (25%) and 36-45 (25%) age groups.

The oral hygiene maintenance of these patients was such that 33 (55%) patients were maintaining oral hygiene. The most prevalent method of oral hygiene maintenance was found to be the tooth brushing, used by 42 (70%) patients. Brushing frequency was once a day for 23 (38%) patients and twice per day for 16 (26%) patients. Most of the patients 40 (61%) presented with pain in mandibular teeth as compared to maxillary (20 patients, 33%). The most common tooth involved in these patients was molar 36 (60%), followed by premolar in 13 (22%) patients. The RCT time elapsed varied from only days (1.7%) to years in 36 (60%) patients. Twenty patients (33%) had months elapsed since RCT while 3 (5%) had weeks elapsed. In 45 (75%) patients, RCT was followed by crowning while 15 (25%) didn’t get benefited by any prosthesis.
