The main goal of pulp therapy in primary dentition is to preserve the primary tooth thus protecting future normal occlusion. Routinely, pulp debridement and canal shaping are done by manual H-files, K-files, Broach, etc. Manual instrumentation may be time- consuming, thus impacting the behaviour of the child negatively. Thus arises the need for alternate instrumentation which will reduce the time required for treatment with better treatment outcomes. In 1988, Walia et al. introduced Nickel-Titanium (Ni-Ti), which revolutionized the discipline of Endodontics. These Ni-Ti files have advantage of shape memory and super elasticity thus improving the canal preparation and resulting in better shaped canals. In 2002, for first time Barr et al reported the use of rotary Ni-Ti files for the therapeutic purpose during Pulpectomy procedure in pediatric patient. He observed better acceptance by pediatric patient and good quality obturation. Till 2016, pulpectomy procedures were accomplished by the combination of hand files and adult rotary files. Adult rotary files are designed according to the morphology for permanent teeth and adult jaw size, thus the use of adult rotary files are in primary teeth may result in lateral perforation due to softer dentine of roots of primary teeth and may cause discomfort to the child thus making child unco-operative. But in 2016, Ganesh et al., pioneered the specialization of Paediatric Endodontics with his invention of specially designed rotary files. Their shape was specially designated for application in tortuous canals of primary teeth. Presently, a variety of pediatric rotary files like Kedo-STM (India), Pro AF Baby GoldTM (India),PrimePedoTM (India), DXL-ProPedoTM (India), NeolixTM (France),Denco® Kids files (China) and, Sani® Kid rotary files (China). This review is an album of these newer files and clinical and in-vitro research on them.

Purpose Many novel materials have been developed such as composite resin, ceramic, zircon or metal-supported ceramic for use in aesthetic restoration of primary teeth and permanent teeth with extensive crown damage. The aim of the present study was to compare microtensile bond strengths on materials using the microtensile bond strength test. Materials and methods The microtensile bond strength on the primary tooth dentin was measured on extracted primary teeth using an indirect method and fracture patterns were evaluated. Results The analysis of bond strengths using the Mann-Whitney U-test did not show significant difference between the rank averages of the compomer and composite resin (p = 0.741). The dentin sections, from which test samples were obtained, contributed to the bond strength; dentin samples obtained just above the pulp had lower bond strength, and the difference was statistically significant (p = 0.005). The adhesive type fracture was the most prevalent fracture type for both materials. Conclusions When the chemical, physiological, and micromorphological differences between primary and permanent teeth are taken into consideration, the success of the materials used for restorations can be different between primary and permanent teeth. Therefore, materials used in the dentistry must be evaluated separately for primary teeth.

Background: the main idea behind the pulpotomy of a primary tooth is to remove the infected or inflamed coronal pulp tissues and cover the pulp with a suitable medicament or dressing which promotes healing and preserve the vitality of the teeth especially in young permanent teeth. A medicament should be biologically compatible, have healing capabilities, should be non cytotoxic, or mutagenic and with no carcinogenic potential. Aim: the main aim of the study was to compare and evaluate the efficacy of commonly used two medicaments i.e. formocresol and sodium hypochlorite in pulpotomy of mandibular primary teeth. Material and methodology: a randomized controlled single blinded clinical trial was done on 50 subjects of age ranging from 3 to 6 years with bilateral mandibular first or second molar requiring pulpotomy. The subjects were randomly divided into two groups with 25 subjects in each. Group I, consisted of subjects on which formocresol medicament was used after extirpation of coronal pulp while in Group II, 3% sodium hypochlorite was used. Clinical along with the radiographic signs and symptoms were blindly recorded at an interval of 1, 3, 6 and 12 months respectively. Results: Statistically significant results were obtained in group II, when patients treated with 3% sodium hypochlorite. There was no major difference between the two medicaments used, but to the various adverse effects of formocresol, its usage has been limited. Conclusion: within the limitation of the study, it was concluded that sodium hypochlorite medicament proved to have better prognosis and can be suggested as a pulpotomy agent for primary teeth. Although formocresol was found to have similar significant results can also be used as a medicament. Keywords: Formocresol, Pulpotomy, Primary Teeth, Sodium Hypochlorite

Most studies dealing with the caries preventive action of Nd:YAG laser have been done in permanent teeth and studies on primary teeth are still lacking. The aim of this study was to evaluate in vitro the effect of Nd:YAG laser combined or not with fluoride sources on the acid resistance of primary tooth enamel after artificial caries induction by assessing longitudinal microhardness and demineralization depth. Sixty enamel blocks obtained from the buccal/lingual surface of exfoliated human primary molars were coated with nail polish/wax, leaving only a 9 mm² area exposed on the outer enamel surface, and randomly assigned to 6 groups (n=10) according to the type of treatment: C-control (no treatment); APF: 1.23% acidulated phosphate fluoride gel; FV: 5% fluoride varnish; L: Nd:YAG laser 0.5 W/10 Hz in contact mode; APFL: fluoride gel + laser; FVL: fluoride varnish + laser. After treatment, the specimens were subjected to a des-remineralization cycle for induction of artificial caries lesions. Longitudinal microhardness data (%LMC) were analyzed by the Kruskal-Wallis test and demineralization depth data were analyzed by oneway ANOVA and Fisher’s LSD test (á=0.05). APFL and APF groups presented the lowest percentage of microhardness change (p<0.05). Demineralization depth was smaller in all treated groups compared with the untreated control. In conclusion, Nd:YAG laser combined or not with fluoride gel/varnish was not more effective than fluoride alone to prevent enamel demineralization within the experimental period.

Developmental Defects Of Enamel

The notion that caries in primary teeth causes developmental defects of enamel in permanent teeth has been recently revived. The research objective was to test this hypothesis through analysis of data from the Dunedin Multidisciplinary Health and Development Study, a longstanding prospective cohort study. The maxillary incisors of 663 children were assessed for existing restorations and dental caries at age five and for developmental defects of enamel at age nine. Where a primary tooth had been carious, the permanent successor was more likely to have a demarcated opacity after adjustment for gender, family socio-economic status, years of exposure to water fluoridation, trauma to primary teeth, and early loss of primary teeth (unadjusted OR = 2.3, 95% CI 1.3, 4.1; adjusted OR = 2.2, 95% CI 1.1, 4.3). These findings support a time-ordered association between dental caries in primary maxillary incisors and demarcated opacities in their permanent successors.

Avulsion of a primary tooth is a disturbing type of traumatic injury occurring in children. Paediatric dentists are likely to encounter a child with an avulsed primary tooth routinely in their clinical practice. Tooth avulsions are common in permanent teeth. However, avulsions can be seen even in primary teeth. The question of replantation of the avulsed tooth has been a focus of debate and controversy since years. The primary and most important factor in these injuries is to calculate the riskbenefit ratio keeping the underlying permanent tooth in mind. Utmost importance has to be given on the care of development and normal eruptive movements of the succedaneous tooth. This is mandatory if any treatment like replantation is to be done. The amount of primary root resorption, stage of development of the underlying permanent tooth, type of splinting to be done etc. needs a lot of attention. Many authors have given their opinions regarding the replantation of primary teeth based on the type of tooth avulsed. Moreover, the evidence might differ as to whether or not replantation might alter the difficulty levels for the eruption process of succedaneous tooth. There is not much evidence regarding the benefits and risks of replantation post avulsion of primary teeth. However, individual authors have reported a successful outcome in their case reports. This article reports a review on avulsed primary teeth replantation. This would enable the dentists to analyze the risks and benefits associated with replantation, thereby guiding them to arrive at the best clinical decision.

Bonding dental materials to dentinal surface, demineralised in particular, still poses a challenge for contemporary dentistry. Adhesion of filling materials to primary tooth tissue poses a greater difficulty compared to permanent teeth due to poorer enamel and intertubular dentin mineralisation and wider dentinal tubules. The bonding strength of dental materials to tooth surfaces depends on, among other things, surface development, the depth of cavity, as well as the associated degree of tissue mineralisation, the content of organic components and water, as well as the number and width of dentinal tubules. The quality of bonding of dental materials to dental tissues is also determined by the mode of substrate preparation, e.g. conventional drilling or air abrasion, and the type of adhesive system used - etch and rinse or self-etch approach. The choice of material that will ensure optimal bonding to the tooth surface under given conditions, i.e. microretention or chemical adhesion, is also important. The aim of the paper was to assess the effects of different methods for primary tooth dentinal surface modification on the adhesion of light-cured materials in experimental studies, based on literature data. The subject of adhesion of light-curing materials to the dentinal surfaces in primary teeth is current and worth further exploration. Self-etching systems are a good solution for filling carious cavities in primary teeth due to less aggressive demineralising effects on dentin compared to phosphoric acid. Demineralised surface is a difficult substrate for adhesive materials, especially in primary teeth; therefore, there is a need for procedures that will improve the retention of light-cured materials in these teeth. The use of air abrasion – mechanical development of the surface combined with chemical modification using self-etching systems may be one of solutions.

Abstract Children are vulnerable to dental trauma, especially in the first two year of life.The objective was to determine whether trauma in temporary teething causes alterations in the development of permanent teething. Searches were made in May 2020 using PubMed, MEDLINE, MEDES, Scopus, Lilacs, and Embase. Papers in English, German, and Spanish, without restrictions in the year of publication, were included. The quality of the studies was analyzed using the NOS Scale.The search retrieved 537 references, and 7 studies were included for a qualitative analysis. The results showed that trauma to a deciduous tooth can damage the bud of the permanent tooth. Enamel discoloration and/or hypoplasia were the most common sequelae in the permanent teeth after trauma to the primary predecessor. The type and severity of sequelae in the permanent tooth are associated with the development phase of the bud. Children with trauma of their primary teeth should receive check-ups until the eruption of the permanent teeth for the early diagnosis and treatment of possible sequelae. Intrusion of the primary tooth was the trauma that caused the most damage and enamel alterations the most frequent sequelae.
