Oral health findings and comprehensive management of a patient with hypotonic cerebral palsy- a case report with a two-year follow-up

Purpose: The purpose of this clinical trial was to assess and compare the clinical outcomes of Bioflx crowns (BFCs) with stainless steel crowns (SSCs) in primary molars (PMs). Materials and Methods: This prospective split-mouth randomized controlled clinical trial was conducted between March 2022 and June 2023. Thirty-eight patients (17 females and 21 males) with a mean age of 5.21 years participated in this study. Each child ( n = 38) received both SSC and BFC. Clinical and radiographic follow-up was performed at baseline, 3, 6, and 12 months using the modified United States Public Health System scoring criteria to evaluate various parameters. Results: At the 3 and 6 months’ follow-up, no significant difference was observed between the two groups. However, at 1-year follow-up, a statistically significant difference ( P < 0.05) was evident in the frequency between the two groups for the criteria of crown retention after cementation and anatomic form of the crown, indicating a preference for SSC over prototype 1 BFC. Conclusion: The 12-month results indicate that BFC performed similarly to the established SSC for the restoration of PMs providing better esthetics.

Objectives. The main purpose of the study was to assess the material wear, antagonistic natural primary teeth wear, and microhardness of zirconia (ZR), a recently launched novel glass-fiber-reinforced composite crown (GFRC). The research question was, are these aesthetic crowns resulting in antagonistic natural primary tooth wear and the crown material itself? Methods. Forty-five primary canines were divided into three groups (15 per group) and mounted against Zr (Group A), GFRC (Group B), and natural teeth as control (Group C) in the wear test machine. All samples were assessed for surface wear with pre- and post-3-dimensional scanning. In addition, microhardness was assessed for all three groups. Results. The mean microhardness value for the Zr disc was 1157 ± 7 HV; for the GFRC disc, it was 29.35 ± 2 HV; while with natural teeth, it was 105 ± 4 HV. There was a statistically significant difference in teeth wear in the prescan and postscan in the natural tooth ( ) group, highly significant difference ( ) in the ZR group, and no significant difference in the GFRC group. Conclusion. There is more significant wear loss of glass-fiber-reinforced composite discs as compared to zirconia. In addition, the wear of the antagonistic tooth with zirconia and natural teeth is more remarkable than with GFRC. There is a vast difference of microhardness between natural teeth and zirconia (almost 10 times higher) which suggests further scope of study. Clinical Relevance. Pediatric dentistry deals with the transition of dentition from primary to permanent through mixed dentition. Selection of restorative material needs to be done cautiously when we are dealing with primary teeth and young permanent teeth as antagonistic teeth. Wear of the crown material itself and opposing natural teeth are essential factors that should be considered in selecting crowns in clinical practice. The present study results can be extrapolated to clinical practice, and the practitioner can consider various factors in selecting full-coverage crowns for primary teeth. The vast difference in aesthetic crowns and natural teeth microhardness indicates a further need for research. Additionally, there is no literature published for the recently launched GFRCs.

To check the efficacy of decompression technique in children with dentigerous cysts. Most commonly occurring odontogenic cysts in the oral cavity are radicular cysts and dentigerous cysts.1 According to Kramer, a cyst is defined as a pathological cavity having fluid, semi-fluid, or gaseous contents, which is not created by the accumulation of pus. A cyst which is lined by epithelium is known as a true cyst and that which is not lined by epithelium known as a pseudocyst.2 The dictionary meaning of dentigerous is "structures resembling teeth".3 A dentigerous cyst is found enveloping the crown of an unerupted, embedded, or submerged tooth by the expansion of its follicle till the neck of the tooth.1 It is not unusual for a dentigerous cyst to mimic a radicular cyst, especially when the cyst is associated with a pulpectomized or carious primary tooth and its unerupted permanent successor. This article presents two cases of infected dentigerous cysts. The first case was of a female patient associated with tooth 45; and another case was of a male patient associated with tooth 35. The infected dentigerous cyst in both the cases was treated with the most conservative option available, i.e., decompression technique. In this article, two cases of infected dentigerous cysts are discussed, in which one case deals with the female patient associated with tooth 45 and the other case deals with the male patient associated with tooth 35. The infected dentigerous cysts in both the cases were treated conservatively, i.e., with the decompression technique. The present case report states that the decompression technique may be the most conservative method available for managing dentigerous cysts in children. Patil AS, Jathar PN, et al.
