Aim: This study was planned to assess the awareness and use of rubber dam in routine practice among the dental practitioners of Navi Mumbai, India. Materials and methods: A Google document with a self-administered validated questionnaire consisting of 14 items was digitally sent to 300 dental practitioners via WhatsApp/e-mail and their responses were collected. Results: The surveyed responses revealed that 261 (88.2%) dental practitioners do not use rubber dam in their routine practice, whereas only 35 (11.8%) use it.

Background/purpose: The most common developmental dental problem is that of agenesis. It is seen to affect around about 25% of the population. The aim of this study is to determine the prevalence of agenesis of third molars in patients visiting a dental college in the UAE. Materials and methods: Orthopantomograms (OPGs) of 945 dental patients aged 6–30 years were evaluated for bilateral agenesis or congenitally missing teeth. Bilateral agenesis was considered and unilateral missing teeth were excluded from the study. Descriptive statistics were used to describe the percentages and frequencies were calculated using Chi-square test and the level of significance was considered if the p value was <0.05. Results: Eighty-five of the 945 OPGs showed bilateral agenesis. The prevalence of bilateral agenesis or congenitally missing third molars within the selected 85 OPGs was at 31.76%. Conclusions: The prevalence rate of bilateral agenesis or congenitally missing permanent third molars is high at 31.76%.

Introduction: In the recent past, rotary files have been introduced for endodontic treatment of primary teeth. However, there is limited literature available which cite the preference of pediatric dentist toward the usage of the rotary and hand endodontic files. Aims and objectives: To assess the preference and perception of pediatric dentists about hand and rotary endodontic files. Materials and methods: A study tool comprising of 21 point questionnaire about pediatric dentist's preference of endodontic files and their perception about clinical effectiveness, advantages, and limitations of the files was administered to 202 pediatric dentists practicing in a metro city. The response was statistically analyzed. Results: 39.7% preferred to use both files, 34.5% preferred to use hand files, and 25.9% preferred rotary files. A respondent felt rotary files are a better option for pulp removal (37.9%) and uniform root canal preparation (70.7%). However, in patients with limited cooperation hand files (62.1%) are preferred. Conclusion: Pediatric dentists preferred to use both hand and rotary files depending upon the clinical situation. Rotary files were perceived to be more clinically effective and hand files were preferred in a patient with limited cooperation.

Aim and objective: The study aimed to compare the dental fear, dental anxiety, and oral health-related quality of life of students of the faculty of dentistry, medical faculty, and other faculties and to examine the relationship between these variables and the demographic data and habits of individuals. Materials and methods: The study involving 1,230 (725 females, 505 males) students from Faculty of Dentistry (n = 439), medicine (n = 498), and other faculties (n = 293) studying at Kırıkkale University. Individuals have applied a questionnaire consisting of questions on oral hygiene habits, dentist visits, smoking and alcohol use in the first part and Dental Fear Scale (DFS), Modified Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) in the second part. Results: Dental fear scale, MDAS, and OHIP-14 scores showed a statistically significant difference between faculties (p < 0.05). The difference between medical students and other faculty students was not significant. Modified Dental Anxiety Scale scores were found to be significantly higher in females than in males (p = 0.005). There was no significant difference in MDAS, DFS, and OHIP-14 between different education years in medicine and other faculties. Conclusions: Dental anxiety, fear levels of dentistry students were lower than other students of other faculties and their quality of life was higher. Dentistry education and the year of education have been found to have a potential impact on the dental anxiety, fear, and quality of life of the individuals.

White spot lesions (WSLs) are a risk of fixed appliance orthodontic treatment (FAOT) with no consensus with regards to prevalence, risk factors, prevention, and treatment. The aim is to screen current clinical opinion by emailing a questionnaire to all orthodontists-members of the British Orthodontic Society. The response rate was 7.85% (115/1,464) and the fully completed questionnaires were 105/115 (91.30%). There was a big difference between the mean (43%) and median (20%) estimated risk for developing WSLs. For the majority of responders, the key factors related to WSLs are clinical examination, photographic records, fluoride, oral hygiene, diet, and duration of FAOT. Clinical relevance: Questionnaire-based study on current clinical practice and opinion with regards to WSLs developing during FAOT. Objective statement: There is a lack of consensus in the literature with regards to estimated risk, risk factors, prevention, and treatment of WSLs developing during FAOT. The reader will obtain a picture of the current clinical practice and opinion of orthodontists on WSLs.

Relevance of the problem and aim and objective: Massive bone and soft tissue defects are seen after oncological maxillofacial operations. Surgeons and prosthodontists must cooperate and make a basic treatment plan. It is essential to improve the quality of life of the patient after completely removing the tumor, restoring masticatory function, and improving esthetic appearance. The study aims to collect and analyze the data of patients with orofacial malignant tumors during the period from 2010 to 2016 in the Hospital of Lithuanian University of Health Sciences (HLUHS) Department of Otorhinolaryngology and Department of Maxillofacial Surgery, National Cancer Institute (NCI) Department of Head and Neck Surgery, Klaipeda University Hospital and find out the availability and their need for rehabilitation and prosthetic treatment. Materials and methods: Patient disease data analysis was performed using the International classification of diseases (ICD) according to malignant tumors localization of the maxillofacial region. The medical records were arranged by age, sex, origin, profession, tumor localization, stage, type, treatment, and prosthetic needs for the patient. Data analysis was carried out using IBM SPSS 25 and Microsoft Excel 2016 software packages. Results: The study involved 827 men and 699 women, the mean age was 68 years. Defects of the lower jaw were detected in 87 patients, of the ear—52 cases in the whole sample. 11.34% of patients required prosthetics to restore the defects after resection. Conclusion: Among 1,526 analyzed cases, prosthetic treatment of the facial defects is required in 11.34% of patients.

Aim and objective: Report unusual foreign bodies lodged in primary and permanent teeth. Background: Children often insert foreign objects inside the teeth to alleviate tooth pain. Such instances are more often reported for permanent teeth as compared to primary teeth. Case descriptions: This case report presents two cases of foreign bodies lodged within the teeth. The first report is a case of a 7-year-old girl who reported pain and examination revealed a pin impacted tooth 54 (FDI nomenclature). The second case reports a case of a 9-year-old girl who presented with pain and on examination, a pencil lead and the nib of a fountain pen was found lodged in tooth 46. In case 1, 54 was extracted considering the poor prognosis of the tooth. In case 2, retrieval of the foreign object was undertaken followed by endodontic treatment because the tooth was permanent and salvageable. Conclusion: In both cases, foreign bodies lodged in the pulp space were found on clinical examination and subsequently confirmed radiographically. The foreign bodies were retrieved successfully and teeth were treated.
