A Comparative Evaluation of the Periodontal Ligament Cell Viability Using Placentrex, Propolis, and Hanks' Balanced Salt Solution: An In-Vitro Study

BACKGROUND AND OBJECTIVES

Most of the dento-alveolar trauma that occurs frequently in childhood is often linked to avulsion injuries. Two considerable elements influencing the prognosis of tooth avulsion after replantation are extraoral dry duration and the characteristics of the storage media to support the viability of cells. The study aimed to compare and assess the effectiveness of Hanks' balanced salt solution (HBSS) (HiMedia Laboratories, Thane, India) and Placentrex (Albert David Limited, Kolkata, India) against propolis (5% and 10%) as storage media in preserving the vitality of periodontal ligament (PDL) cells.

MATERIALS AND METHODS

Four groups with 15 samples each were selected for the study. Sixty recently extracted premolars were left to incubate for 30 minutes in 15-ml falcon tubes containing 2.5 ml of collagenase 0.2 mg/ml in phosphate-buffered saline and 2.4 mg/ml of dispase in HBSS, Placentex, propolis 5%, and propolis 10%. After the addition of bovine serum, it was centrifuged for 4 minutes. Trypan blue 0.4% was utilized to recognize the cells, and a hemocytometer was employed for counting the live PDL cells under a light microscope.

RESULTS

Propolis 5% and 10%, HBSS, and Placentrex all showed statistically significant differences in PDL cell viability; however, HBSS was significantly outperformed by Placentrex and propolis.

CONCLUSION

Placentrex is a superior substitute storage medium in cases of tooth avulsion as opposed to alternatives such as propolis 5% and 10%.

Anticipatory Guidance through Online Motivational Interviewing for Mothers on Early Childhood Caries among Young Children of Age 9-24 Months amidst Pandemics: A Nonrandomized Clinical Trial

Early childhood caries (ECC) is a multifactorial disease with known etiologic factors and can be very devastating to the oral and general well-being of a child, including psychological impact on a growing child. The irony is among the different factors responsible for milk that is wholesome nutrition, if fed in a wrong pattern, can be the main factor that helps this type of rampant caries spread within no time, leading to pulp exposures and complicating proceedings. Awareness is the mainstay in prevention, and creating it becomes our sole responsibility as a pediatric dentists. A multidisciplinary approach with the involvement of mothers as a main stakeholder in this front becomes a very promising move, so this project is phase two of interprofessional collaboration involving mothers in prevention; the aim of the study is to create awareness among mothers during COVID lockdown so as to prevent ECC in this covid pandemic.

Materials and methods

A total of 222 mothers with 9-24 months old children were selected and added to the e-groups. The allocated mothers were given a pretest questionnaire and collected back with a photo of their child's oral health, and anticipatory guidance and in-depth interviewing were given to them. Follow-up is done in 2, 4, and 6 months. Awareness is evaluated by pre- and posttest questionnaires. Reversal of the white spot is evaluated through indices, and progression is noted.

Statistical analysis

The data was analyzed using Statistical Package for the Social Sciences 13.

Result

Pretest and postquestionnaire analysis were done using the Chi-squared test. The test shows the marked raise in knowledge, attitude, and practice of mothers on their children after postintervention, which was given through motivational interviewing (MI).

Conclusion

In summary, the MI intervention appeared to improve maternal knowledge but had no effect on oral health behaviors or on the progression of early childhood caries (ECC).

Comparative Evaluation of Fixed Functional Cantilever Space Maintainer and Fixed Nonfunctional Space Maintainer: A Randomized Controlled Trial

Background and objectives

Effective way to prevent mesial drift after the early loss of primary first molars is by inserting a durable space maintainer. Several space maintainers are available; fixed nonfunctional (FNF) space maintainer (crown and loop) is commonly used when abutment teeth need full-coronal restoration. Disadvantages of crown and loop space maintainer are nonfunctional, nonesthetic, and fracture of solder loop. To overcome this drawback, new design of fixed functional cantilever (FFC) space maintainer (crown and pontic) using bis-acrly composite resin. The study evaluated the longevity and acceptance of an FFC and compared it with a FNF space maintainer.

Materials and methods

A total of 20 healthy children, aged 6-9 years, were selected having bilateral premature loss of lower deciduous first molars. FFC space maintainer in one quadrant and FNF space maintainer in the other was cemented. The subject's acceptance of treatment was checked using a visual analog scale after the treatment completion. Criteria for complication leading to the failure was assessed in both the designs in the 3rd, 6th, and 9th month. Cumulative success longevity was obtained at a 9 month evaluation.

Results

Patient acceptability was greater in group I (FFC) in comparison to group II (FNF). In group I, fracture of the crown and pontic was the common complication leading to failure, followed by attrition of the crown and loss of material due to abrasion. In group II, fracture of the solder joint was the common complication leading to failure, followed by slippage of the loop gingivally and cement loss. The longevity of groups I and II were 70 and 85%, respectively.

Conclusion

FFC can be considered a viable alternative to conventional FNF space maintainers.

Gingival, oral hygiene and periodontal status of the teeth restored with stainless steel crown: A prospective study

AIM

To compare the gingival health and periodontal status in primary molars restored with stainless steel crowns with unrestored contralateral teeth.

MATERIALS AND METHODS

A split mouth design study was conducted on 60 children aged 5- 10 years who required stainless steel crown restoration on deciduous molars. The molar teeth restored with stainless steel crown were selected for study and healthy unrestored contralateral teeth were selected as controls. Bitewing radiograph of study and control tooth was taken at initial, three months and at six months. The gingival status, oral hygiene status was evaluated at three months and six month intervals using gingival index and oral hygiene index respectively.

RESULT

On evaluating the oral hygiene status at three months study group showed the mean value of 0.7±0.700 whereas in control group it was 1±0.368. At six months it was 1.183±0.390 in study group and 1.5±0.504 in control group. Chi square test shows that the crown marginal adaptation produced statistically significant difference at six months. Crown marginal extension did not produce any difference on gingival index and oral hygiene index.

CONCLUSION

When compared to control teeth, the teeth restored with stainless steel crown showed lesser plaque and debris accumulation at three months and six months. Radiographic bone level the control teeth showed higher level of bone resorption compared to the teeth restored with stainless steel crown.
