Open bite is the absence of vertical overlap of lower incisors by upper incisors when posterior teeth are in occlusion. An anterior open bite can cause periodontal damage which leads to gingivitis and periodontitis. To assess the gingival health status in patients with anterior open bite and also compares with patients without an anterior open bite. Retrospective data collected from 89,000 case records from June 2019 to March 2020. The present study consisted of 76 patients divided into two groups: patients with anterior open bite and patients without an anterior open bite. In both groups, the following parameters were recorded - Oral Hygiene Index - Simplified (OHI-S) and Plaque Index (Silness and Loe). OHI-S index and plaque index was similar in patients with and without an anterior open bite. Mean Plaque Index for case group (patients with anterior open bite) is 0.76, and Mean Plaque Index for control group (patients without the anterior open bite) is 0.78. Mean OHI-S Index for case group (patients with anterior open bite) is 0.51, and Mean OHI-S Index for the control group (patients without the anterior open bite) is 0.53. The difference was not statistically significant (P-value > 0.05). In this study, gingival health status in patients with and without an anterior open bite is low.

Radiology is one the key cornerstone of investigation in Dentistry. The application of radiology in Dental practice has grown by leaps and bounds in the years gone by. Along with this there is an increase in the number of radiation hazards.  The effect of  radiation  on  human  beings  is  very  negative. This survey was conducted with the intent of studying the awareness and knowledge of radiation protection in practice. The survey consisted of 10 closed ended questions which were circulated among 100 interns of a dental college. The data collected was entered into microsoft excel and the data was analysed for an association between the gender and the responses using Chi-square analysis. The majority of the participants were females and they believed that radiation causes harm to humans and surprisingly they had also believed that ionised radiation remains suspended in the air after making a radiographic exposure where there was no statistically significant difference between the genders(p>0.05). The questions also assessed whether a clinical examination is advised before a radiographic examination and the majority were of the view it is necessary which was statistically significant(p<0.05). From this study we could infer that students are well aware of the adverse effects of radiation but in terms of safety practices being followed in Dental clinics, there are some pitfalls noticeable.

Anterior crossbite is a type of malocclusion involving anteroposterior alignment, which results from an abnormal axial inclination of the anterior maxillary teeth. Dental caries is a chronic disease affecting patients and adults. Due to improper oral hygiene management in individuals with a crossbite, the incidence of caries could be higher. Hence a study was conducted to assess the dental caries status in patients with anterior crossbite and also compare with patients without anterior crossbite. The present study consisted of 56 patients divided into two groups: patients with anterior crossbite and patients without anterior crossbite. 89000 Case sheets were reviewed from the dental treatment records for DMFT index in patients with and without anterior crossbite from June 2019 to March 2020. In both groups, parameters such as Decayed- Missing - Filled (DMFT) score was recorded. Data were subjected to the Mann Whitney U test in SPSS software. Results showed higher DMFT score was seen in patients without anterior crossbite. Mean DMFT Index for case group (patients with anterior crossbite) is 2.04, and Mean DMFT Index for the control group (patients without anterior crossbite) is 2.93. The difference was not statistically significant (P-value - 0.072). Within the limitations of the study, dental caries status in patients with anterior crossbite is good compared with patients without anterior crossbite.
