BiodentineTM versus formocresol pulpotomy technique in primary molars: a 12-month randomized controlled clinical trial.

BACKGROUND: The objective of this clinical study was to prospectively compare the clinical and radiographic success rates of BiodentineTM pulpotomies versus formocresol pulpotomies in children vital primary molars. METHODS: A randomized, split-mouth study design was used with a sample of 37 healthy children aged 4- to 8-year-old. A total of 56 pairs (112 teeth) of carious primary teeth, 1 pair per child, were selected for treatment. One tooth from each pair was randomly assigned to either the BiodentineTM pulpotomy group or the formocresol pulpotomy group. Children were followed-up at 3, 6 and 12 months for clinical evaluation and at 6 and 12 months for radiographic evaluation. Data were collected, tabulated and analyzed using Fisher exact and McNemar tests. The level of significance was set at P < 0.05. RESULTS: At 12 months, the clinical success rates of both BiodentineTM and formocresol groups were 100%, while the radiographic success rates for BiodentineTM and formocresol groups were 100% and 98.1%, respectively. There was no statistically significant difference between both groups (P=1). The only observed radiographic failure was furcal radiolucency in the formocresol group at 12-month interval. Pulp canal obliteration was radiographically observed in 10/56 (17.9%) and 7/56 (12.5%) cases in the BiodentineTM and formocresol groups, respectively. CONCLUSIONS: Both BiodentineTM and formocresol pulpotomy techniques demonstrated favorable clinical and radiographic outcomes over a 12-month period without any significant difference.

Comparison between biodentine and formocresol for pulpotomy of primary teeth: A randomized clinical trial.

OBJECTIVE: To assess and compare the clinical and radiographic success rates of biodentine and formocresol for pulpotomy in human primary teeth. METHOD AND MATERIALS: A randomized, split-mouth, double-blind, controlled clinical trial was carried out in 37 healthy 4- to 8-year-old children with 56 pairs (112 teeth) of contralateral primary molars indicated for pulpotomy. Matched teeth in each pair were randomized to undergo either biodentine (n = 56 teeth) or formocresol (n = 56 teeth) pulpotomy. In both groups, the teeth were restored with stainless steel crowns. The teeth were evaluated clinically and radiographically at 3 and 6 months by two blinded, standardized, and calibrated examiners. The data were analyzed using chi-square and McNemar tests with a P value of < .05 considered significant. RESULTS: At both the 3- and 6-month follow-ups, all the 37 children with 112 treated teeth were evaluated. Clinical and radiographic success was similar for biodentine (100%) and formocresol (100%), without any statistically significant difference (P = 1). Pulp canal obliteration was radiographically observed in 10/56 (17.9%) and 7/56 (12.5%) cases in the biodentine and formocresol groups, respectively. CONCLUSION: Both pulpotomy techniques showed favorable clinical and radiographic outcomes at 3 and 6 months posttreatment without any significant difference. Hence, biodentine has the potential to become a substitute for formocresol in primary molar pulpotomies.

Molar incisor hypomineralization, prevalence, and etiology.

Aim. To evaluate the prevalence and possible etiological factors associated with molar incisor hypomineralization (MIH) among a group of children in Jeddah, Saudi Arabia. Methods. A group of 8-12-year-old children were recruited (n = 267) from the Pediatric Dental Clinics at the Faculty of Dentistry, King Abdulaziz University. Children had at least one first permanent molar (FPM), erupted or partially erupted. Demographic information, children's medical history, and pregnancy-related data were obtained. The crowns of the FPM and permanent incisors were examined for demarcated opacities, posteruptive breakdown (PEB), atypical restorations, and extracted FPMs. Children were considered to have MIH if one or more FPM with or without involvement of incisors met the diagnostic criteria. Results. MIH showed a prevalence of 8.6%. Demarcated opacities were the most common form. Maxillary central incisors were more affected than mandibular (P = 0.01). The condition was more prevalent in children with history of illnesses during the first four years of life including tonsillitis (P = 0.001), adenoiditis (P = 0.001), asthma (P = 0.001), fever (P = 0.014), and antibiotics intake (P = 0.001). Conclusions. The prevalence of MIH is significantly associated with childhood illnesses during the first four years of life including asthma, adenoid infections, tonsillitis, fever, and antibiotics intake.
