This study aimed to assess the success of pulpotomy in primary molars using Biodentine, new-developed tri-calcium, di-calcium-based silicate cement, at 6 and 12 months. The hypothesis was that stages of root resorption could influence the treatment success. A novel composite score was used based on five clinical and radiographic outcomes: soft-tissue pathology, pain to percussion, pathologic mobility, radiolucency and pathologic root resorption. Patients’ compliance and intraoperative pain experience were recorded using the Frankl scale and the Wong–Baker scale. A total of 22 primary molars, 9 in stage S (stability) and 13 in stage R (resorption) were submitted to pulpotomy using Biodentine and restored with composite resin. The success rate was 92.3% in the R group compared to 100% in the S group at both 6 and 12 months (p = 0.850). There was no statistically significant effect of type of molar, tooth position and type of carious lesions on the composite outcome (all p > 0.05). Overall, 73% of the children experienced no or mild/moderate pain and 77% had a cooperative attitude. Children younger than 7 years old experienced more pain (p = 0.04). Biodentine is a promising biomaterial for pulpotomy of primary teeth regardless of the stage of root resorption.
Aim: To determine the association between dental anomalies and type of facial cleft, gender, ethnicity and timing of hard palate repair surgery. Methods: This observational study comprised a total of 85 non-syndromic cleft children (mean age 9.7 ± 3.2 years) of different ethnicity (68 Caucasians, 7 Asians, 4 Africans, 5 Hispanics and 1 Indian). Sixty-four patients were affected by lip palate cleft, 11 by lip alveolus cleft and 10 by palate cleft. Sixty-one children underwent delayed palate repair at 4.3 years of age, while 21 underwent early palate periosteoplasty at 7.2 months of age. Patients were examined clinically and radiologically to assess dental anomalies. Dental cavities were registered using dmft/DMFT indexes in primary and permanent dentition, while enamel defects were evaluated only in permanent teeth using Aine index. Results: Tooth rotation and agenesis were the most common tooth anomalies affecting 59% and 42.2% of cleft patients, respectively. While a late closure of the cleft palate was associated with a higher number of rotations (P = 0.03), an early surgical correction was associated to a higher frequency of tooth agenesis (P = 0.02), number of carious lesions in primary dentition (P = 0.002) and more severe enamel defects in permanent teeth (P < 0.01). A late palate repair increased 3.5 times the likelihood of having at least one rotated tooth (P = 0.034), while decreased the odds of having agenesis by 70% (P = 0.029) compared to an early surgical repair. Conclusion: Early surgical approaches seem to have more detrimental effects on dental development in both primary and permanent dentition than late surgical protocols. Dental abnormalities in cleft patients have complex etiology combining genetic and external factors and their prevalence can also depend on timing of hard palate surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
