Introduction: Age estimation is a critical aspect of forensic science, with various methods employed, including skeletal development, dental maturation, and anthropometric measurements. Cervical vertebrae maturation is a reliable biological marker of skeletal maturity, and its use in combination with other techniques can enhance accuracy in age estimation.

Aim: This study aimed to categorize individuals as under or over 18 years of age by evaluating cervical vertebrae and permanent molar maturation in the Dakshina Kannada population.

Materials and methods: A total of 132 individuals were categorized into two groups: under 18 years and over 18 years. Data were collected using orthopantomograms (OPG) and lateral cephalograms (LC). Cervical vertebral age was determined using the McNamara and Franchi technique, while dental age was assessed using Nolla's method.

Results: Age was significantly associated with the shape, inferior border, and stage of cervical vertebrae, as confirmed by Pearson's Chi-square test. Binary logistic regression analysis showed that combining skeletal and dental maturity indices improved the accuracy of age classification.

Conclusion: Cervical vertebrae maturation, in conjunction with dental age estimation, serves as a reliable method for accurately determining age, particularly for distinguishing individuals over and under 18 years. The analysis revealed no significant difference in correlation between males and females, Additionally, the findings indicate that cervical vertebral maturation (CVM) can provide a rough estimate of age, demonstrating its potential utility in age prediction with reasonable accuracy.

Aim: To evaluate the color-retaining ability of three different esthetic restorative materials used in pediatric dentistry with the use of commonly consumed health drinks and beverages.

Materials and method: 180 discs were made using three different restorative materials with each group (Group A) GC Gold Label Type IX GIC, (Group B) Voco Ionolux RMGIC, and (Group C) Shofu Beautifil II GIOMER containing 60 discs per group. Four types of commonly consumed drinks were taken as immersion media, which included Complan Health Drink, Coca-Cola aerated beverage, Cavin's milkshake, and Bisleri mineral water (control). Each disc of restorative material were immersed in the staining solution of commonly consumed drinks at three different frequencies for 15 days. Color changes were measured using a spectrophotometer at pre-immersion and post-immersion levels.

Results: Change in color was evaluated and a comparison was done between the groups. There was a highly significant difference ( P < 0.005) in the color-retaining ability of Shofu Beautifil II GIOMER restorative material followed by GC Gold Label Type IX GIC and Voco Ionolux RMGIC against all immersion media.

Conclusion: The color-retaining ability of the esthetic restorative materials on immersion in various beverages and health drinks depends not only on different immersion media but also on different frequencies of consumption. Shofu Beautifil II GIOMER restorative material showed the most color retention.

Aim: To evaluate the efficacy of propolis and its combination products as an obturating material in comparison to Vitapex.

Materials and methods: Propolis collected from the primary source was extracted using organic solvents and laboratory bio-assayed against Enterococcus faecalis to evaluate its minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). For in-vivo studies, propolis efficacy was investigated in combination with zinc oxide and calcium hydroxide powder. Furthermore, pulpectomies were performed on 68 non-vital primary molars in the children of age group 4-8 years and were assessed both clinically and radiographically.

Statistical analysis: The data were subjected to chi-square test for comparative analysis.

Results and conclusions: Zinc oxide in combination with propolis resorbed at the same pace as that of the roots. MIC and MBC of laboratory-extracted propolis against E. faecalis were 289 and 579 μg/mL, respectively. Efficacies of different obturating materials were observed as ZnOP > ZnO{Ca(OH)2}P > Ca(OH)2P > Vitapex. A novel herbal obturating material with ideal properties for primary teeth has been developed.

Background: Developing methodological approaches and instrumentation in psychological research is critical since the variables and constructs in the field are diverse and must be assessed with appropriate instruments. Each instrument produced or altered must undergo content validation. The content validation method involves a readability test to determine whether the questions or items accurately represent the assessed constructs or variables.

Aim: This study aimed to illustrate the steps involved in content translation, adaptation, and validation of Mindful Attention Instruction Script (MAIS) as a novel behavior management technique during local anesthesia procedures in children 9-12 years old exhibiting dental fear and anxiety.

Methods: MAIS was subjected to various steps to assess its content validity which included, obtaining consensus from the panel of experts, back translation of the script by a subject matter expert, adaptation of the MAIS, preliminary pilot testing for the target group, and conducting content validation.

Results: MAIS achieved a satisfactory content validity score of 0.9 and interrater agreement of 0.8.

Conclusion: This study showed acceptable levels of validity in the Kannada and Hindi translated versions, illustrating a valid and reliable tool to be used for the evaluation of MAIS that applies to the Indian population.

Abstract: While performing any prosthodontic rehabilitation, the accuracy of diagnostic wax-up is proportional to the predictability of end treatment result, as it forms a template for the provisional as well as final restorations. The most common challenge faced by dental clinicians in severely worn dentition patients is the difficulty to program the condylar guidance on an articulator using eccentric bite records, due to loss of anterior guidance and interferences in the posterior teeth. Conventionally, in such cases, an arbitrary diagnostic wax-up followed by an intraoral temporization is done to obtain the incisal guidance first, and the condylar guidance is later programmed in the presence of posterior disocclusion using eccentric bite records. However, this increases the chairside time and clinical visits. Therefore, this article describes the use of a customized bifunctional incisal jig to record centric relation at the desired occlusal vertical dimension along with programming the condylar guidance before a diagnostic wax-up is performed.

Background and aim: Myofascial pain dysfunction syndrome (MPDS) is one of the most important facial muscle disorders comprising signs and symptoms including pain during function, tenderness in the muscles of mastication and restricted jaw movement. The purpose of this study was to assess and compare the effectiveness of low-level laser therapy (LLLT) and combination therapy of LLLT and pharmacotherapy in the treatment of myofascial pain with or without other TMD (temporomandibular disorders).

Materials and methods: Forty patients with MPDS were randomly divided into two groups. Group 1 received LLLT (Biolase™; GA-Al-As; 940 nm) in 12 sessions. Group 2 received a combination of LLLT with the drug Aceclofenac 200 mg till the end of the 12 th session. Following each session and after two months, the pain intensity, maximum mouth opening, clicking sound and jaw deviation were evaluated in both groups. Data were collected and analysed using the independent t test, Mann-Whitney U test and Friedman test ( a = 0.05).

Results: Both group 1 and group 2 showed a significant reduction in pain and a significant increase in mouth opening, which was faster in group 2 compared to group 1.

Conclusion: Both LLLT and a combination of LLLT and drug therapy are effective in the management of myofascial pain. LLLT + pharmacotherapy combination is more efficient at improving pain and mouth opening.

Background: During pregnancy, an interim increase in estrogen and progesterone levels is found responsible for the enhanced frequency and intensity of gingival inflammation. The risk of various complications such as an increase in preterm low birth weight and preeclampsia raises a serious concern about the knowledge and awareness of pregnant women regarding periodontal health.

Aim: To evaluate periodontal status and assess knowledge and awareness of poor oral health and its effect among pregnant women.

Materials and methods: A total of 240 pregnant women underwent a questionnaire and observational evaluation. Socioeconomic demographic data based on the revised Kuppuswamy Socioeconomic Status Scale, age, gender, and medical & dental history were recorded using structural proforma. The Community Periodontal Index and Treatment Need (CPITN) index was used to evaluate the periodontal status of pregnant women in different trimesters.

Result: A statistically significant association was observed between the CPITN score and trimesters. Out of 50 subjects with a CPITN score of 2, 46.0% were in the third trimester. On the evaluation of 240 subjects, 63.3% visited the dentist when a problem arose and 57.5% used interdental aids. Also, 45.4% of pregnant women encountered oral health problems during pregnancy. Furthermore, 81.3% of pregnant women were unaware of the adverse effects of poor oral health on a growing fetus.

Conclusion: In the current study, it has been discovered that only a small percentage of pregnant women are conscious of their periodontal health and that their beliefs vary depending on their degree of education. When compared to the first trimester, the patients in the third trimester have impaired periodontal conditions.
