(1) Background: Molar-incisor hypomineralization (MIH) is a common clinical condition with critical negative consequences for dental health. The etiology of MIH is still not completely understood, although several theories have been suggested. (2) Aim: To investigate the etiology of MIH defects in a sample of Saudi school children. (3) Method: A total of 893 school children in the age range of 8–10 years participated in the study. The sample was taken from Riyadh City, Saudi Arabia. The participating children were examined for MIH using the European Academy of Pediatric Dentistry Criteria. The children’s parents were asked about the child’s pre, peri-, and postnatal condition utilizing a structured and validated questionnaire. (4) Results: A total of 362 children (168 males and 194 females) were affected with MIH, for a prevalence of 40.5%. Among all analyzed etiological factors, only jaundice was found to be significantly associated with MIH in children (OR = 1.35, p = 0.047). Multivariate logistic regression analysis confirmed that the only significant etiological factor for MIH was newborn jaundice (p = 0.04). (5) Conclusion: Newborn jaundice was the only etiological factor that showed a significant association with MIH in the studied Saudi school children.

The purpose of the study is to correlate the parenting styles of parents with the oral health of their children, in Riyadh, Saudi Arabia. Two hundred and eighty healthy preschool children, who have never been to the dentist, were recruited. Parenting style was determined by the Parenting Style and Dimensions Questionnaire (PSDQ). World Health Organization (WHO) criteria and simplified debris index (DI-S) were used for the diagnosis of dental caries and oral hygiene of the children respectively. Two parenting styles were identified among Saudi parents; authoritative (94%, n = 265) and permissive (6%, n = 17). The majority of children were brushing by themselves (n = 130, 46.1%) and once per day (n = 130, 46.1%). Significant correlations were detected between parenting style and children’s brushing times (P-value of 0.016) and the number of meals consumed by children (P-value of 0.031). The age of the child and oral hygiene score were significantly correlated to dental caries (P-value < 0.05). Two parenting styles were identified among Saudi parents. Parenting style influenced the child’s oral health but not significantly. Early childhood caries and fair to poor oral hygiene were commonly detected among children. Clinically interesting correlations were identified regarding factors affecting the child’s oral health status.

BioFlx crowns (BFCs) have been introduced in the dental market, combining the flexibility of stainless steel crowns (SSCs) with the esthetic appeal of preformed zirconia crowns. However, the existing literature does not provide adequate insights regarding the retentive strength of various types of luting cement with these newly developed BFCs. Therefore, this study aimed to evaluate and compare the retentive strength of BFCs and SSCs with different types of luting cement (glass ionomer cement [GIC], resin-modified glass ionomer cement [RMGIC], self-adhesive resin cement [SARC], and polycarboxylate cement [PXC]). A total of 160 standardized resin dies were fabricated and divided into two groups based on the type of crown (BFCs or SSCs). Each group was further subdivided into four subgroups (20/group) based on the luting cement used for cementing the crown on the die. A pullout test was performed using a universal testing machine to measure the retentive strength required for crown dislodgement. The residual cement in the crown was scored to determine the cement failure pattern. Data were analyzed using two-way analyses of variance (ANOVAs) to evaluate the interaction between the cement and the type of crown on retentive strength, followed by an independent t-test. Furthermore, Welch’s ANOVA and Dunnett’s T3 test were used to assess the impact of various types of luting cement on the retentive strength of each crown. The CFP was assessed by comparing the scores using descriptive statistics. Statistical significance was set at p < 0.05. The mean retentive strength of SSCs and BFCs was the highest with SARC (560.29 ± 8.74 N; 657.72 ± 20.60 N), followed by RMGIC (534.20 ± 22.84 N; 454.90 ± 7.95 N) and GIC (435.14 ± 8.66 N; 237.68 ± 9.37 N), while the lowest was with PXC (365.67 ± 19.11 N; 131.26 ± 5.37 N). A significant difference in retention was observed between the crowns (p < 0.05). Cement failure primarily manifested as adhesive failures in the SARC and RMGIC groups; however, both adhesive and cohesive failures occurred in the GIC and PXC groups. Thus, SSCs demonstrate significantly higher retention than BFCs across all types of luting cements, except when using SARC. Within the limitations of this in vitro study, SSCs emerge as the preferred choice for full-coverage restorations that require optimal retention and durability. Nevertheless, BFCs with SARC provide a viable alternative when esthetic considerations are prioritized.

Aim: To evaluate the effects of placing short posts made of different restorative materials on the fracture resistance of root canals in primary incisors of primary teeth. Materials and Methods: The root canals of 40 extracted primary incisors were prepared and filled with Vitapex and randomly divided into five groups of 8 each. In Groups 1-4, a post space was created and filled with different restorative materials (Tetric (R) N-Ceram Bulk Fill, AeliteFlo, Filtek Z250 XT, and GC Fuji II LC (R) capsule), while Group 5 was kept filled with Vitapex as a control. Fracture resistance was measured using a universal testing machine at a 0.5-mm/min crosshead speed. The results were statistically analyzed and compared. Results: The highest fracture resistance was recorded for GC Fuji II LC capsules [439.82 N] and control [423.37 N], while the lowest fracture resistance was recorded for Tetric (R) N Ceram Bulk Fill (239.91 N). A multiple comparison test showed that the Tetric (R) N-Ceram Bulk Fill had a significantly lower average value than AeliteFlo (P = 0.030), as well as a significantly lower average value than GC Fuji II LC (R) capsule (P = 0.001), and a significantly lower average value than the control group (P = 0.002). Multiple comparison tests showed no significant difference between Tetric (R) N-Ceram Bulk Fill and Filtek Z250 XT (P = 0.39). Conclusion: The fracture resistance of primary incisor root canals differs according to the material used for the intracanal posts. Three-millimeter intracanal posts in the primary incisors showed the highest fracture resistance for the teeth restored with GC Fuji II LC capsules and the control.

Background: Effective pain management during dental procedures is essential to ensure positive treatment outcomes, particularly for pediatric patients. Intraosseous anesthesia, administered via the QuickSleeper system, has shown promise as an alternative to traditional local anesthesia techniques. Methods: A single-blinded split-mouth randomized controlled clinical trial took place at the dental hospital at King Saud University with 33 healthy patients (aged 4–9 years), who required pulpotomies and stainless steel crown procedures on two mandibular primary molars, to evaluate the effectiveness of two local anesthetic techniques. Each tooth was randomly assigned to receive 4% articaine either delivered via the intraosseous route using QuickSleeper 5 or buccal infiltration. The effectiveness of the anesthesia was evaluated by the number of injections needed and at various stages using the Sounds, Eyes, and Motor (SEM) scale. Postoperative complications, including pain, swelling, and lip numbness, were assessed through follow-up phone calls with the patients’ legal guardians. Results: The techniques demonstrated comparable effectiveness; there were no statistically significant differences in the number of injections and in the SEM scale scores. Minimal postoperative complications were reported: lip biting (two cases) and prolonged numbness (nine cases) were reported only when buccal infiltration was used, and swelling and pain were reported when both techniques were used. Conclusions: Intraosseous anesthesia via the QuickSleeper 5 system is comparable to traditional buccal infiltration anesthesia for pulpotomies and stainless steel crown procedures in pediatric mandibular molars. Intraosseous anesthesia offers the added benefit of reduced soft tissue numbness and associated complications.
