The primary dentition plays a very important role not only in the child's growth and development but also in the guidance and eruption of permanent teeth. Premature loss of a deciduous tooth or a group of teeth will lead to a wide range of implications in the permanent dentition. The best way to avoid these problems is to preserve the primary teeth in the arch until their normal time of exfoliation. However, in cases where extraction of teeth is unavoidable due to extensive caries, the safest option to maintain arch space is by placing a space maintainer. The present case report is about a 4-year-old male patient with bilaterally decayed, nonrestorable primary maxillary first molars. After examination and radiographic investigations, it was decided to extract teeth 54 and 64. Since the permanent successors were still in Nolla's stage 4, a space maintainer was planned to prevent any migration and space loss. To encourage a positive outcome, it was decided to carry out prosthetic intervention using a Nance appliance with functional components. After the replacement of the missing teeth, a marked improvement in function, along with space maintenance, was seen.

Nasal breathing protects the upper airway and is responsible for adequate craniofacial development. It is believed that long-standing obstruction causes mouth breathing, which has a negative impact on the craniofacial complex.

Aim: The study aimed to verify the effects of mouth breathing on the dentofacial structure by employing cephalometric analysis.

Materials and methods: The present study was conducted on 68 patients (34 mouth-breathing group or study group and 34 nasal-breathing group or control group) aged 6-14 years. Study subjects were screened based on the inclusion and exclusion criteria. Clinical assessment of nasal function was done to select the mouth breathing patients and referred for ear, nose, and throat (ENT) clearance. Lateral cephalograms were taken for the study subjects, including both nasal and mouth breathers, over which selected landmarks were marked to evaluate linear, skeletal, and dental angular variables for comparison with cephalometric variables of a normal child.

Results: The mean values of facial height (N-Me, ANS-Me) and mandibular plane angle (SN-GoGn) were significantly higher for mouth breathers. The gonial angle (Ar-GoMe) for ages 6-14 years was significantly lower in the nasal breathing group.

Conclusion: The study led to the conclusion that all subjects with a history of mouth breathing showed an increase in facial height, gonial angle, and mandibular plane angle.

Clinical significance: Evaluating dentoskeletal changes in a patient with a mouth-breathing habit helps discern the importance of early identification and interception at an early age, thereby ensuring a functional environment adequate for physiological growth and dentofacial esthetics.

Introduction: Early childhood caries (ECC) is a major common problem seen in children and is the most prevalent chronic disease that leads to discomfort, pain, and poor quality of life, affecting the health of children. Alkaline phosphatase (ALP) is a nonspecific phosphomonoesterase that functions through a phosphoery 1 intermediate to produce free inorganic phosphate. It has different isoenzymes produced by different cell types such as polymorphonuclear leukocytes, osteoblasts, macrophages, and fibroblasts within alveolar bone and/or salivary glands. Various studies show that higher ALP activity is related to periodontal disease and dental caries.

Aim: This study aims to estimate and correlate salivary Alkaline Phosphatase enzyme activity in the saliva of children with and without ECC.

Materials and methods: A total of 50 children were included in the study, divided into two groups-caries-active and caries-free, each consisting of 25 participants. Unstimulated saliva samples were collected and subjected to a spectrophotometer for analysis. ALP enzyme activity levels were estimated and correlated between caries-active and caries-free children.

Results: The correlation between caries score and ALP activity was statistically significant, with a moderate correlation. The comparison of mean ALP activity between caries-active and caries-free groups was statistically significant. However, the comparison of ALP based on different age-groups and gender was not statistically significant. There was a statistically significant correlation between caries scores and the caries-active group.

Conclusion: In conclusion, there is a substantial correlation between ALP enzyme levels and the severity of dental caries. An increase in ALP enzyme level is linked to a considerable rise in caries severity. Therefore, prevention may be possible with early detection.

Background: Dental caries is the most common disease in childhood and has an impact on general health status. The topical application of fluoride varnishes has been used for the prevention and control of dental caries due to their high fluoride content, adhesion capacity, and safety. Silver has a varied application in medicine as well as in dentistry due to its anticaries, antimicrobial, and antirheumatic potentials. The introduction of nanosilver fluoride (NSF) was made with advancements in technology to overcome the drawbacks of silver diamine fluoride (SDF).

Aim: To compare and evaluate the microhardness and microleakage of NSF varnish and sodium fluoride (NaF) varnish.

Materials and methods: An in vitro comparative experimental study was carried out between synthesized NSF and commercially available NaF, with 20 samples in each group. The specimens were sectioned and subjected to microhardness evaluation using Vickers microhardness testing and the dye penetration method to evaluate the microleakage.

Results: The average microhardness was found to be 230.7218 VMH for NSF (group I), 198.9841 VMH for NaF (group II), and 91.6120 VMH for group III. These differences were statistically significant when compared with each other (p = 0.002). In 50% of the samples, no dye penetration was seen in the NSF group, compared to the NaF varnish group, where 75% of the samples exhibited penetration onto the varnish interface or the varnish and tooth interface.

Conclusion: Nanosilver fluoride proves to be an effective alternative to commercially available topical fluoride agents such as NaF. It has greater microhardness and lower microleakage than NaF and the control teeth.

Clinical significance: Nanosilver fluoride varnish can be used as a cost-effective alternative to NaF varnish and SDF. It can be applied with minimal training by healthcare workers or general practitioners.

Objective: To evaluate the reduction of microbial loading using Morinda citrifolia (M. citrifolia), Triphala, and Camellia sinensis (C. sinensis) as irrigating agents in deciduous molars after pulpectomy.

Materials and methods: A controlled, randomized clinical trial involving 150 multirooted deciduous molars from both genders between 6 and 9 years old children were included, 30 molars irrigated with M. citrifolia (group I), Triphala (group II), C. sinensis (group III), chlorhexidine (CHX) (group IV), and saline (group V) each. In all cases, two microbiological samples from within the canal were taken with sterile paper points, one before the first irrigation and the other immediately after pulp extirpation. Cleaning and shaping were completed with intermittent irrigation with 10 mL of experimental irrigants in the initial visit. After 3 days, reentry to the root canal was obtained, rinsed with 5 mL of the test irrigants, and the second microbial sample was collected. All the microbial samples obtained were cultured under anaerobic conditions on blood agar. The colony-forming units (CFUs) were counted using a colony counter. Data was analyzed using paired student t-test and Tukey's post hoc test.

Results: After analysis of the pre- and postsamples in all groups, a strong significant decrease in bacterial load (p ≤ 0.001) was found with CHX, M. citrifolia, and Triphala.

Conclusion: Morinda citrifolia (M. citrifolia) and Triphala, with effective antimicrobial efficacy, can be suggested as an alternative root canal irrigant as CHX, while C. sinensis was found ineffective in reducing microbial count as normal saline.

Aim and background: The management of avulsed immature teeth poses a significant challenge to clinicians, as prolonged dry time before reimplantation may lead to replacement resorption or ankylosis.

Case description: Recent studies have shown promising results with the use of an intracanal proprietary pharmaceutical preparation, followed by sealing of the orifice with mineral trioxide aggregate (MTA). Angiography suggested the presence of vascularized tissue after 1 year, indicating successful regeneration of pulpal tissue in the radicular area.

Conclusion: Despite an unfavorable crown-root fracture leading to tooth extraction after 9 months, histological examination revealed regular root dentin formation, indicating a favorable outcome.

Clinical significance: These findings offer hope for the management of avulsed immature teeth and underscore the importance of early intervention and appropriate treatment selection.
