Caries Risk Assessment of 12-13-year-old Government and Private School Going Children of Mysore City Using Cariogram: A Comparative Study.

AIM: The aim of this study is to assess the caries risk assessment of 12-13-year-old government and private school going children of Mysore city using Cariogram. MATERIALS AND METHODS: A cross-sectional examination was carried out on a total of 104 government and private schoolchildren aged 12-13 years. Ten factors from the Cariogram software(D Bratthall, Computer software, Malmo, Sweden) were included from study participant's records to complete the Cariogram. The percentage of "chances of avoiding new lesions" (caries risk) among government and private school study participants were obtained from Cariogram, and the participants were classified into five risk groups. Statistical analysis was performed using the software program Statistical Package of Social Science (version 17.0, SPSS Inc., Chicago IL, USA). RESULTS: Findings revealed that there is slight difference in caries risk among government and private schoolchildren, where 48% caries risk development and 52% chance to avoid dental caries were showed in government schoolchildren, and 51% caries risk development and 49% chance to avoid dental caries were showed in private schoolchildren, according to Cariogram. Decayed, missing, and filled teeth component, mutans streptococci, and Lactobacillus counts were slightly higher in private schoolchildren compared with government schoolchildren. CONCLUSION: The private schoolchildren had less favorable values than government schoolchildren for most of the caries-related factors. Cariogram can be the most modest and reliable tool for caries prediction, thus aiding in identifying different risk groups in a community so that appropriate preventive strategies can be provided to overcome new carious lesion formation.

Platelet-rich Plasma and Incidence of Alveolar Osteitis in High-risk Patients Undergoing Extractions of Mandibular Molars: A Case-control Study.

BACKGROUND: To evaluate the efficiency of platelet-rich plasma (PRP) on the incidence of alveolar osteitis (AO) in patients with potential risk factors for the development of AO. MATERIALS AND METHODS: This study was conducted in 150 patients visiting the outpatient department of oral and maxillofacial surgery. Patients with potential risk factors for the development of AO which included smokers, alcoholics, postmenopausal women, patients on oral contraceptives, pericoronitis, and bruxism were included for the study. Patients were randomly divided into two groups. Group A consisted of 75 patients in which PRP was placed in the socket after extraction. Group B consisted of 75 patients in which sockets were left for normal healing without the placement of PRP. The patients were assessed for pain and dry socket on the 3rd and 5th postoperative day. RESULTS: All the local signs and symptoms of inflammation were mild to moderate and subsided in normal course of time. Pain was less in Group A where the extraction sockets were treated with PRP. Soft-tissue healing was also statistically significant on the PRP treated site when compared to the other group where PRP was not placed into the socket after extraction. The incidence of AO among the patients who have the potential risk factor for the development of the same was significantly reduced in Group A. CONCLUSION: The study showed that autologous PRP is a biocompatible material and has significantly improved the process of soft-tissue healing, reduced pain, and decreased the incidence of AO in the extraction socket when treated with PRP.

Comparative Evaluation of Neem Mouthwash on Plaque and Gingivitis: A Double-blind Crossover Study.

AIM: The present study aimed at evaluating the impact of neem-containing mouthwash on plaque and gingivitis. MATERIALS AND METHODS: This randomized, double-blinded, crossover clinical trial included 40 participants aged 18 to 35 years with washout period of 1 week between the crossover phases. A total of 20 participants, each randomly allocated into groups I and II, wherein in the first phase, group I was provided with 0.2% chlorhexidine gluconate and group II with 2% neem mouthwash. After the scores were recorded, 1-week time period was given to the participants to carry over the effects of the mouthwashes and then the second phase of the test was performed. The participants were instructed to use the other mouthwash through the second test phase. RESULTS: There was a slight reduction of plaque level in the first phase as well as in the second phase. When comparison was made between the groups, no statistically significant difference was seen. Both the groups showed reduction in the gingival index (GI) scores in the first phase, and there was a statistically significant difference in both groups at baseline and after intervention (0.005 and 0.01 respectively). In the second phase, GI scores were reduced in both groups, but there was a statistically significant difference between the groups only at baseline scores (0.01). CONCLUSION: In the present study, it has been concluded that neem mouthwash can be used as an alternative to chlorhexidine mouthwash based on the reduced scores in both the groups. CLINICAL SIGNIFICANCE: Using neem mouthwash in maintaining oral hygiene might have a better impact in prevention as well as pervasiveness of oral diseases as it is cost-effective and easily available.

Association between Cheiloscopic Patterns and ABO Blood Groups among South Indian Population.

BACKGROUND: Human beings have few characteristics that are unique from others. Lip prints are one of such feature. They are not changed throughout the life and are not influenced by injuries, diseases, or environmental changes. According to the various antigen-antibody reactions in the bloodstream, different individuals have specific blood groups. AIM: To study the distribution of lip print patterns among individuals with different ABO and Rh blood groups and also to know the relation between their characters and blood groups. MATERIALS AND METHODS: In the present study, lip prints were collected randomly from 85 individuals, and their blood group matching was performed. This is to identify the most common lip print type and to know any association between lip print types and blood groups. Tsuchihashi's classification of lip prints was used to compare with the ABO and Rh blood grouping systems. RESULTS: It was observed that in individuals with B+, A+, and O- blood groups, predominant pattern was Type IV and individuals having blood group O+ and AB+ common lip print pattern was Type II. CONCLUSION: This study showed strong association between lip print patterns and ABO blood groups as some blood groups were not included in statistical analysis; further studies including larger sample are essential to substantiate the results. CLINICAL SIGNIFICANCE: Correlating lip print with blood group helps in identification of the suspects. Along with lip prints, another biological record that remains unchanged throughout the lifetime of a person is the blood group. Determining the blood group of a person from the samples obtained at the site of crime and also recovering lip prints from site can help identify a person.
