Aim: This study aimed to investigate the correlation between subjective pain threshold (SPT), daily pain recovery (PR) during the first postoperative week, and patient/surgical characteristics, while evaluating changes in SPT across multiple surgeries. Additionally, it assessed how perceived quality of life correlates with SPT and PR in adolescents undergoing lower third molar germectomy.

Methods: A prospective clinical study was conducted at the Paediatric Surgery Unit, Sapienza University of Rome, involving 51 patients aged 10-16 years undergoing lower third molar germectomy. SPT and daily PR were measured using the Visual Analogue Scale (VAS) during the first postoperative week, and quality of life was evaluated using the SF-12 questionnaire at 1-week follow-up.

Results: A total of 87 germectomies were performed, with 36 patients undergoing a second surgery. The mean age was 13.86 ± 1.81 years. Mean VAS scores increased from 4.2 ± 1.5 for Intervention 1 to 4.8 ± 1.6 for Intervention 2. Longer operative times were associated with higher PR scores on postoperative day 3. Higher PR scores correlated with greater limitations in daily activities and emotional well-being, while lower PR scores were linked to better self-perceived health.

Conclusion: SPT and PR are influenced by surgical duration and self-health perception. Shorter procedures and positive self-health perception contribute to faster recovery and improved postoperative quality of life in young patients.

Purpose: This study aimed to determine the prevalence of hypomineralised second primary molars (HSPM) and molar incisor hypomineralisation (MIH) in cleft lip and/or palate (CL/P) patients.

Methods: A retrospective analysis of intraoral photographs of CL/P patients was done. All patients born between 2000 and 2011, and visiting the cleft team of the Erasmus Medical Center in Rotterdam, The Netherlands, were included. Their photos were scored on the presence and severity of HSPM and MIH using criteria formulated by the European Academy of Pediatric Dentistry. The outcomes were compared with data of the general population, extracted from the Generation R study.

Results: The photos of 535 CL/P patients were evaluated. The overall prevalence of HSPM in CL/P patients was 15.2%, of MIH 12.8%. HSPM and MIH prevalence was significantly higher (both p < 0.001) compared to prevalence in the general population. No significant differences were found in prevalence of HSPM nor of MIH in CL/P patients based on gender (p = 0.891 resp. p = 0.405), cleft type (p = 0.282, resp. p = 0.415), Pierre Robin (p = 0.837, resp. p = 0.169) or other comorbidities (p = 0.553, resp. p = 0.617). CL/P patients with HSPM were almost 3 times more likely diagnosed with MIH than CL/P patients without HSPM (OR = 2.57, p = 0.002).

Conclusion: The prevalence of HSPM and MIH is higher in patients with CL/P than in the general population.

Purpose: This systematic review aims to consolidate existing genetic and clinical data on non-syndromic dentinogenesis imperfecta (DI) to enhance understanding of its etiology.

Methods: Electronic databases were searched for genetic familial linkage studies published in English without time restrictions. Genetic familial linkage studies that reported cases of Shield's classifications: DI-II, DI-III or DD-II were included. After removing duplicates and excluding non-eligible articles, two reviewers screened relevant articles independently, followed by data extraction.

Results: The systematic search identified 3475 articles, with 135 suitable for full-text review and a final 41 that met inclusion criteria. Within this set of studies, 10 conducted a histopathologic examination of teeth from affected participants. DSPP mutations were the most frequently reported, with 59 documented mutations. Four studies identified mutations in COL1A1 and COL1A2, revealing non-syndromic DI cases, predominantly in individuals of Asian descent. Histopathological analysis of affected teeth showed variations in pulp chamber size, dentinal tubule irregularities, enamel malformations, and mineral density reductions, depending on DI phenotype.

Conclusions: This review consolidates genetic and clinical data to advance the understanding of non-syndromic DI. It highlights the role of DSPP, COL1A1 and COL1A2 and the potential involvement of other genes, emphasizing the effectiveness of whole-exome sequencing in identifying causative mutations.

Purpose: To assess the impact of the picture exchange communication system (PECS) on oral hygiene motivation and practices in healthy children aged five to seven years.

Methods: A total of 160 healthy children aged five to seven years were included in this study. At the first visit, the participants' guardians were asked to answer a questionnaire focussing on the sociodemographic, and the oral hygiene habits of the participants. All participants received a clinical examination to assess their dental caries experience using the ICDAS score, gingival condition using the gingival index (GI), and the amount of accumulated dental plaque using the Turesky Modification of the Quigley-Hein Plaque Index (TQHI), followed by comprehensive explanation of the proper oral hygiene protocol. The participants were randomly divided into two equal groups; the PECS group and the control group. The participants were re-assessed after 6 months. The collected data were statistically analysed using the Statistical Package for Social Sciences (SPSS) software version 23 at a p-value ≤ 0.05.

Results: By the end of the follow-up period, the PECS group reported significantly greater adherence to regular tooth brushing (p = 0.006) with a frequency higher than twice per day (p < 0.000) and no need for parental motivation (p < 0.001), and had significantly lower mean GI and TQHI scores (p < 0.000). Most of the participants' guardians reported that the PECS cards were useful for use and that they would continue to use them 66/76 (86%).

Conclusion: The PECS was found to be effective in motivating children to adhere to proper tooth-brushing practices, as reflected by improvements in their oral health status and gingival condition.

Purpose: To evaluate and compare the effect of two enzymatic chemo-mechanical caries removal agents with conventional caries removal using rotatory instruments on the adhesion of composite resin to dentin of permanent teeth.

Methods: The sample comprised 30 permanent molars with caries lesions extending to the dentin, randomly distributed into three groups (n = 10 each): 1-Caries removal with rotary instruments (control group); 2-Caries removal with Papacárie Duo^® (F&A Laboratório Farmacêutico, São Paulo, Brazil); 3-Caries removal with Brix 3000™ (Brix S.R.L., Carcarañá, Argentina). After caries removal, the specimens were rinsed and dried. Scotchbond Universal™ adhesive (3 M, Saint Paul, Minnesota, USA) was actively applied in self-etch mode and light-cured. Resin composite increments were applied using a silicone mold (3 × 3 × 2 mm) and light-cured. Shear bond strength (MPa), work-to-debonding (J/m²), and shear modulus (kPa) were evaluated. For statistical analysis, the level of significance was set at 5%.

Results: The control group presented significantly higher shear bond strength values (8.50 ± 2.69 MPa) compared to the Brix 3000™ group (5.72 ± 1.55 MPa, p = 0.008). There were no significant differences between Papacárie Duo^® (6.66 ± 0.86 MPa) and the other groups (p > 0.05). Regarding work-to-debonding, the Papacárie Duo^® group had a significantly higher result (2944.41 ± 450.21 J/m²) than the Brix 3000™ group (1189.41 ± 504.13 J/m², p < 0.001) and the control group (967.10 ± 270.01 J/m², p < 0.001). Concerning shear modulus, the control group showed a significantly higher result (558.67 ± 168.96 kPa) than the Brix 3000™ group (339.79 ± 143.78 kPa, p = 0.008) and the Papacárie Duo^® group (223.04 ± 127.30 kPa, p < 0.001).

Conclusion: While the application of Papacárie Duo^® did not negatively affect composite resin adhesion to dentin of permanent teeth, the application of Brix 3000™ reduced adhesive forces, potentially limiting its clinical use. Further investigations are warranted to elucidate the effects of these materials on dentin substrate, particularly through clinical studies.

Purpose: The present systematic review aims to summarize the current evidence regarding various treatment modalities and their results when dealing with hypersensitivity in teeth with Molar-Incisor Hypomineralization (MIH).

Methods: Systematic searches were conducted in PubMed and Scopus using the search terms "MIH AND Hypersensitivity AND treatment." Studies involving children aged 6-18 years diagnosed with MIH and exhibiting hypersensitivity were considered for inclusion. The outcomes examined included clinical, behavioral, and psychosocial treatment options for reducing hypersensitivity. A meta-analysis was performed for six of the included articles, and the I² value was calculated to determine heterogeneity.

Results: A total of eight articles met the inclusion criteria for this review, with six eligible for the meta-analysis. Various treatment modalities, such as dental mousse, sealing, laser therapy, and crown therapy, demonstrated significant reductions in hypersensitivity individually (p < 0.05).

Conclusion: The treatment methods that offer the most effective reduction in hypersensitivity are sealing with resin composite or glass ionomer cement for mild cases of MIH, while crown therapy is more effective for severe cases of MIH. However, the small number of participants and short follow-up times limit the strength of these conclusions.

Purpose: Equimolar oxygen-nitrous oxide mixture (EMONO) is considered as a reference for dental care in children. Completion of dental treatment has usually been used as a criterion to assess EMONO treatment. However, other patient-reported outcomes are needed. We sought to assess the prevalence of complete therapeutic effects (analgesia and anxiolysis) experienced by children during dental care under EMONO and identifying associated factors.

Methods: A national prospective observational multicentric study was conducted between September 2018 and June 2020 in 13 French university hospitals. Participants were children between 3 and 15 years of age requiring dental care under EMONO.

Results: 677 children were analyzed. Anxiolysis and analgesia were experienced by a large majority of patients (86.5% and 79.0%, respectively, and 73% experienced both effects). Several factors were associated with both analgesia and anxiolysis effects: the presence of expected effects (no loss of judgment and slight decrease in level of consciousness), the absence of agitation and distress, a positive perception of EMONO and ethnicity.

Conclusion: Most patients benefit from the therapeutic effects (anxiolysis and analgesia) expected by EMONO during dental treatment. It is reassuring to observe that most sociodemographic characteristics and medical history do not seem to influence the effectiveness of care. The study was registered at www.

Introduction: Dental caries is the most common chronic disease worldwide, and various forms of fluoride are considered useful preventive tools. The production of nanoscale materials can significantly improve their mechanical and chemical properties. The present study compared the microhardness of primary tooth enamel after applying sodium fluoride varnish (conventional) and nano-sodium fluoride varnish.

Materials and methods: Sixty-eight sound canine teeth were selected in this experimental study. The teeth were mounted so that the buccal surface was exposed. A 3 × 3 mm square was obtained on the buccal surface of the crown of each tooth. Enamel surfaces were polished using sandpaper in the presence of water as a coolant. The samples were randomly divided into four groups (n = 17): G1, conventional 5% NaF; G2, 1% nano-NaF; G3, 5% nano-NaF; G4, control. The initial microhardness was measured. Before surface treatment with different fluoride compounds, the samples were placed in a demineralizing solution for two days, and the microhardness of all the samples was re-measured. Then G1, G2, and G3 were treated with the fluoride type specified for each group, and G4 was treated as a control (without treatment). Finally, pH cycling was applied, and the microhardness was measured again. Data were analyzed with SPSS 20, using Repeated measure ANOVA and post-hoc Tukey tests. P < 0.05 was considered significant.

Results: Repeated measure ANOVA showed that microharness of G1, G2, G3, and G4 was statistically significant different. Tukey tests showed that the microhardness of G1, G2, and G3 were not significantly different. However, these three groups exhibited significantly more microhardness than the control group (P = 0.024, P = 0.027, and P = 0.010).

Conclusion: There was no significant differences in enamel microhardness of deciduous teeth between conventional 5% NaF,1% nano-NaF and 5% nano-NaF.
