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.

Abstract: Periodontal disease is a common condition caused by bacterial plaque that damages the supporting structures of teeth. Therefore, to manage periodontal disease, probiotic supplementation has emerged as a potential adjunct therapy. This umbrella review aims to summarize the primary findings, conclusions, and recommendations of systematic reviews and meta-analyses published on the effect of probiotics in treating periodontal disease. A systematic review of the literature was undertaken in four databases, i.e., MEDLINE, Embase, Cochrane Central, and Google Scholar using MeSH terms like 'Probiotic*,' 'Prebiotic*,' 'Bifidobacterium,' 'Lactobacillus,' and 'Periodontitis,' along with keywords like 'synbiotic*,' 'Systematic review*,' or Meta-analysis. The AMSTAR-2 tool was used to assess the quality of the included reviews once data were retrieved. A total of 22 systematic reviews and meta-analyses published in the last decade were reviewed, and probiotics were found to have potential benefits in reducing Bleeding on Probing (BOP), Probing Pocket Depth (PPD), and gaining Clinical Attachment Level (CAL) in individuals with periodontal disease. However, there is mixed evidence on the effectiveness of probiotics in reducing gingival inflammation (GI) and dental plaque, and further research is needed to understand the mechanisms of action and potential health benefits of probiotics. The findings of this review suggest that probiotics as an adjunct treatment approach may have potential benefits for managing periodontal disease specially in terms of BOP, PPD, and CAL. However, they should not replace conventional treatments like scaling, root planing, and regular dental hygiene, which are essential for effective care.

Abstract: The maxillary anteriors play the most prominent role in an individual's aesthetics, speech, and majorly psychology. The impaction of maxillary anterior teeth can be a challenging orthodontic problem that can be managed by interceptive orthodontics in early mixed dentition. In this particular case report, interceptive orthodontics alone may not bring desirable results because two problems need to be dealt simultaneously, namely, intraosseous crowding and midline shift due to impaction on the affected quadrant. In the article, a novel approach is being discussed, where aesthetics of the child was compromised due to impacted rotated maxillary anteriors that were exposed using soft tissue laser and allowed to erupt by selective removal of primary and permanent first premolar teeth on the affected side alone, leading to spontaneous alignment of arch discrepancy and relative correction of midline shift. A unilateral serial extraction sequence (D-4-C) would be effective treatment of choice. This approach adds psychological benefit to the child by using soft tissue lasers and unilateral serial extraction.

Context: Dental caries is a multifactorial disease that affects large segment of population worldwide.

Aim: To evaluate the detailed relationship between carious status of primary molars and permanent first molars among 8.5-10 years old children.

Methods and materials: Two-hundred and seven children were included in this cross-sectional study. The permanent incisors were fully erupted, the primary canines had no caries experience, and premolars were not erupted. The dentition status of the primary molars and permanent first molars was examined according to the World Health Organization criteria.

Statistical analysis used: Pearson correlation, independent sample t-test, and linear and logistic regression analysis were used. The significance level was set at 0.05.

Results: The mean (standard deviation) of decay, missing and filled teeth/surface for primary molars and permanent first molar (dmfs&dmft/DMFS&DMFT) were 4.12 (2.53), 8.40 (7.43), 0.77 (1.16) and 1.01 (1.81), respectively. Weak and medium correlations were found between d-component and D-component (r < 0.5), though statistically significant (P value < 0.001). Moreover, there was a relationship between the number of primary molars caries and the presence of caries on the permanent first molar located in the same side and jaw of these primary molars and those located in the opposite side and jaw of the primary molars.

Conclusion: Nearly one-fifth of the caries on the permanent molars might be attributed to caries on the primary molars among 8.5-10 years-old children. The odds ratio of developing caries on the permanent first molars was 1.5 for children with primary molars caries in comparison to children with no primary caries.

Abstract: Oligodontia is a severe type of tooth agenesis involving six or more congenitally missing teeth, excluding the third molars. It is a rare condition and has a low prevalence in deciduous dentition. It can occur either as a part of syndromes or as a separate entity. This is a rare case report of a 3-year-old child with congenitally missing bilateral anterior and posterior deciduous teeth and its aesthetic and functional rehabilitation using a fixed appliance known as modified Hollywood bridge. In this appliance, molars are banded and acrylic teeth were secured to the stainless steel palatal wire with the help of heat cure acrylic resin. Modified Hollywood bridge provides a reasonable treatment option for the replacement of the missing deciduous teeth in children. It is more suitable for younger paediatric patients and also for physically or mentally handicapped patients.

Background: India launched the National Oral Health Program (NOHP) in the year 2014-15 to support the states for improved oral healthcare delivery and reduce the burden of oral diseases. The toll-free Interactive Voice Response System (IVRS) with contact number 1800112032, was initiated to deliver oral health-related information to users and guide them for proper treatment on World Oral Health Day on 20th March 2017. There is scarcity of data regarding the utility and perception of users about IVRS. This study will try to underpin the factors, which can be useful in further improvement in the helpline operation.

Aims: To assess the perception of patients regarding the use of the existing IVRS helpline under NOHP for oral health-related information.

Methods and material: The present cross-sectional nonclinical dental survey was carried out among 980 adults aged 18 years and above visiting SCB Dental College and Hospital, Cuttack, Odisha.

Statistical analysis: Descriptive statistics with proportions were calculated and Chi-square was computed, P < 0.05 was considered significant for all statistical inferences.

Results: None of the participants were aware of the existence of the toll-free helpline number of NOHP. A significantly higher proportion of female participants responded that IVRS was useful in getting unassisted oral health-related information (P < 0.001).

Conclusions: The services of IVRS remains underutilised by the general population due to lack of awareness regarding its existence. The IVRS helpline can be readily accessed for information regarding common oral diseases, immediate home-based care and when to approach for professional help for the common oral health issues.
