Minocycline hydrochloride ointment combined with Vitapex paste is effective for middle-aged and elderly patients with combined periodontal-endodontic lesions.

OBJECTIVE: This study was designed to determine the efficacy of minocycline hydrochloride ointment (MHO) combined with Vitapex paste on middle-aged and elderly patients with combined periodontal-endodontic lesions (CPELs) and its effect on the inflammatory factors. METHODS: The data of 88 elderly patients with CPELs treated in the First Affiliated Hospital of Gannan Medical University from March 2020 to March 2022 were analyzed retrospectively. Among them, the patients treated with MHO and iodoform zinc oxide clove oil paste were assigned into the control group (n = 42) and the rest of the patients treated by MHO and Vitapex paste were assigned to the study group (n = 46). The inflammatory factors, periodontal indexes and efficacy were determined and compared between the two groups. The MOS 36-Item Short-Form Health Survey (SF-36) was adopted to evaluate the quality of life (QoL) of patients before and after treatment. Additionally, the adverse reactions of the two groups during treatment were analyzed and compared. The prognosis of the two groups of patients was analysed, and factors impacting their prognosis was analysed through the Logistic regression analysis. RESULTS: Before treatment, the levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) were not significantly different between the two groups (all P > 0.05), while after treatment, these levels in both groups decreased significantly, with notably lower levels in the study group than those in the control group (all P < 0.05). Before treatment, the gingival index (GI), plaque index (PLI), probing depth (PD) and bleeding index (BD) of the two groups were similar (all P > 0.05); however, after treatment, the levels of GI, PD, PLI and BI of both groups decreased significantly (all P < 0.05), with more notable decreases in the study group than those in the control group (all P < 0.05). The study group showed a significantly higher overall response rate than the control group (P < 0.05). Before treatment, the SF-36 scores of the two groups were not significantly different (P > 0.05), while after treatment, both groups had significantly increased SF-36 scores, and the score in study group was significantly higher than the control group (P < 0.05). In addition, the incidence of adverse reactions was not notably different between the two groups (P > 0.05). According to univariate analysis, age, dental lesion grade, course of disease, and persistent dull pain were the risk factors affecting the prognosis of patients. According to multivariate analysis, dental lesion grade was the independent risk factor affecting the prognosis. CONCLUSION: MHO combined with Vitapex paste is effective for middle-aged and elderly patients with CPELs, which can effectively inhibit the patients' inflammatory reaction and improve their periodontal condition and QoL, with a low adverse reaction rate, so it is worthy of clinical promotion.

Effect of conventional needle irrigation, passive ultrasonic irrigation, sonic irrigation and XP-endo finisher in removing intracanal Vitapex paste.

To compare the efficiency of conventional needle irrigation, passive ultrasonic irrigation, sonic irrigation and XP-endo Finisher in removing Vitapex paste from root canals. The root canals of human single-rooted teeth were prepared and obturated with Vitapex paste. After 2 weeks, the 48 teeth were randomly allocated into four groups: conventional needle irrigation (CNI) group, passive ultrasonic irrigation (PUI) group, sonic irrigation (SI) group and XP-endo Finisher (XP) group. The specimens of four groups were scanned using a micro-computed tomography after the Vitapex pastes was removed. The results showed that more residual paste was left in the CNI group than in the other three groups (p < 0.05). There was no significant difference among the PUI, SI and XP group (p > 0.05). And, the majority of the residual Vitapex was found in the apical third, with a small amount in the middle third after using any of the three agitated irrigation techniques.

A retrospective study of iRoot BP Plus pulpotomy compared with Vitapex pulpectomy for irreversible pulpitis of primary molars with the presence of coronal pulp tissue.

BACKGROUND: Pulpotomy has been successfully performed in immature and mature permanent teeth with irreversible pulpitis but rarely in primary teeth. AIM: To evaluate the outcomes of iRoot BP Plus pulpotomy and Vitapex pulpectomy in primary molars with irreversible pulpitis. DESIGN: We selected 130 primary molars of 99 patients, aged 3-7 years, diagnosed with irreversible pulpitis with coronal pulp tissue and treated with iRoot BP Plus pulpotomy or Vitapex pulpectomy (median follow-up period: 18 months). They were divided into the pulpotomy (n = 88) and pulpectomy (n = 42) groups according to treatment procedure. The pulpotomy group was further divided into asymptomatic (n = 46) and symptomatic (n = 42) subgroups according to preoperative symptoms. The chi-squared test and Cox regression were performed to analyze the outcomes. RESULTS: Clinical and radiographic success rates were significantly higher in the pulpotomy group (98.9% and 95.5%) than in the pulpectomy group (88.1% and 54.8%) and did not differ significantly between asymptomatic and symptomatic pulpotomy subgroups. CONCLUSION: Irreversible pulpitis of primary molars with coronal pulp tissue can be successfully treated with iRoot BP Plus pulpotomy. Early intraradicular resorption of materials is the main adverse outcome of Vitapex pulpectomy.

Comparative study of pulpal responses to ProRoot MTA, Vitapex, and Metapex in canine teeth.

BACKGROUND/PURPOSE: ProRoot MTA, Vitapex, and Metapex are widely used for pulp treatment of primary tooth. The aim of this study was to compare the pulpal responses to ProRoot MTA, Vitapex, and Metapex in a canine model of pulpotomy. MATERIALS AND METHODS: Pulpotomy procedure was performed to 34 teeth (21 incisors and 13 premolars) and ProRoot MTA, Vitapex or Metapex was applicated to artificially exposed pulp tissues. After 13 weeks, the teeth were extracted and processed with hematoxylin-eosin staining for histologic evaluation. All specimens were evaluated in several categorys related to calcific barrier, inflammatory responses and the area of calcific barrier formation was measured. RESULTS: Most of the specimens in the ProRoot MTA group developed a calcific barrier at the pulp amputation site and showed a low level of inflammatory response. However, in comparison to ProRoot MTA group, a small amount of calcific barrier formed in Vitapex and Metapex groups. CONCLUSION: This in vivo study found that Vitapex and Metapex induced similar pulpal responses but showed poor outcomes compared with using ProRoot MTA. Vitapex and Metapex are therefore not good substitutes for ProRoot MTA in direct pulp capping and pulpotomy.

Evaluation of Success Rate of Lesion Sterilization and Tissue Repair Compared to Vitapex in Pulpally Involved Primary Teeth: A Systematic Review.

BACKGROUND: Vitapex has been a popular obturating material for several decades. In recent times, lesion sterilization and tissue repair (LSTR) has shown promising results. This technique uses a mixture of 3 antibiotics for sterilization of the root canals and healing of periradicular tissues. OBJECTIVE: The objective of this systematic review was to compile all the literature comparing Vitapex and LSTR for pulpally involved primary teeth and evaluate the success rate in terms of clinical and radiographic outcomes. MATERIALS AND METHODS: This review is based on PRISMA guidelines. The electronic search on MEDLINE via PubMed database and Google scholar, cross-referencing and hand search of journals was carried out for articles from January 1, 2000 to December 31, 2019. Articles only in the English language were selected. Out of the 17 articles, 3 unique articles were identified for the review, of which 2 were randomized controlled trials and 1 was a retrospective study. RESULTS: All the three articles were assessed for their quality and all had a low risk of bias. It was found that LSTR and Vitapex had a high clinical success after 12 months. The radiographic success after 6 months was high but decreased after 12 months in both the groups. CONCLUSION: There is no difference in the success rate of LSTR as compared to Vitapex for the treatment of pulpally involved primary teeth.

Clinical and Radiographic Evaluation of 3Mix and Vitapex as Pulpectomy Medicament in Primary Molars: An In Vivo Study.

OBJECTIVE: To evaluate the clinical and radiographic success rates of 3Mix and Vitapex in the treatment of necrosed primary teeth. MATERIALS AND METHODS: Seventy teeth of healthy children aged 4-9 years with necrotic primary molar (nonvital) were treated with 3Mix (lesion sterilization tissue repair therapy) and Vitapex before restoration with stainless steel crowns. The participants were followed up clinically and radiographically for 3 months and 6 months, respectively. The outcome was compared using Fisher exact test with a significance level of p < 0.05. RESULTS: Clinical success rate of 3Mix group at 3 months and 6 month follow-up was 100% and 97.14% and that of Vitapex group was 100% and 100%, respectively. The radiographic success rate of 3Mix group at 3 months and 6 months was 74.29% and 77.14% and of Vitapex group was 97.14% and 97.14%, respectively. Considering the clinical success, no statistical difference was found between the two groups at the end of 6 month (p = 1.000). But radiographically statistical significant difference was found between the two groups (p = 0.028). CONCLUSION: Non-instrumentation endodontic treatment using 3Mix has shown a good clinical success of 97.14% but the radiographic success rate at 6 months was lower (77.14%). So it can be suggested that the use of 3Mix antibiotic treatment cannot replace conventional root canal treatment over the long term.

Effect of Calcium Hydroxide Based Intracanal Medicaments on the Apical Sealing Ability of Resin Based Sealer and Guttapercha Obturated Root Canals.

INTRODUCTION: Calcium Hydroxide (CH) is one of the most commonly used intracanal medicaments which can be used with various vehicles. AIM: The aim of this in vitro study was to evaluate the effect of three CH based intracanal medicaments on the apical sealing ability of AH Plus - guttapercha obturation. MATERIALS AND METHODS: Crowns of 100 extracted single rooted human teeth were sectioned at the Cemento-Enamel Junction (CEJ) to a standardized length. The root canals were instrumented upto ISO size 40 using step back technique and the specimens were randomly divided into two control and four experimental groups. The control groups were not medicated. Specimens in positive control group (Group I) were obturated with guttapercha without placing sealer and in negative control group (Group II) were obturated with guttapercha and AH Plus sealer. Among the experimental groups, specimens of Group III were not medicated while groups IV, V and VI were medicated with CH-saline, CH-2% Chlorhexidine (CHX) and Vitapex respectively for a period of 14 days. The medicaments were removed from the specimens and the teeth were obturated with AH Plus sealer and guttapercha using lateral compaction technique. The specimens were immersed in India ink dye, demineralized and diphanized. The extent of dye penetration was assessed using a 10X stereomicroscope. Data obtained was statistically analyzed by one-way ANOVA (p<0.05) followed by Post-hoc Tukey test. RESULTS: Amongst the three CH medicaments, CH-2% CHX when used as an intracanal medicament showed a significantly higher microleakage as compared to the other groups with p<0.001. The microleakage values between the remaining groups were not statistically significant. CONCLUSION: Under the conditions of this study it was concluded that all groups with or without intracanal medicament showed apical leakage. The vehicle used to carry CH may significantly influence the apical sealing ability of guttapercha - AH Plus obturated canals.

Single Versus Multi-visit Endodontic Treatment of Teeth with Apical Periodontitis: An in vivo Study with 1-year Evaluation.

BACKGROUND: Apical periodontitis (AP) is one of the most prevalent diseases of the teeth. Treatment of AP is based on the removal of the cause, i.e., bacteria from the root canals. Achievement of adequate bacterial eradication in one appointment treatment remains a controversy. AIM: This prospective study was conducted with the objective to compare the periapical healing of teeth with AP treated in (a) single visit versus (b) two visits, either with or without Vitapex as an intracanal medicament. SUBJECTS AND METHODS: Patients were selected randomly from the Department of Conservative Dentistry and Endodontics. Forty-three patients (81 teeth) met the inclusion criteria, i.e., AP (both symptomatic and asymptomatic) visible radiographically size ≥2 mm × 2 mm, not suffering from any immune-compromising disease, age between 16 and 65 years and tooth not accessed previously. Patients were randomly divided into three groups, i.e., single-visit group (Group 1), multi-visit group without any intracanal medicament (Group 2), and multi-visit group with Vitapex as interim intracanal medicament (Group 3). Comparison was done radiographically using periapical index (PAI). The primary outcome measure was the change in periapical radiolucency after 1 year assessed by PAI scores. The Mann-Whitney U-test was used to evaluate differences between groups at baseline (immediate postoperative) and at the 12-month follow-up evaluation. Change in PAI score for each group from baseline to 12-month follow-up evaluation was tested with the Wilcoxon signed rank test. The secondary outcome measures, proportion of teeth in each group that could be considered improved (decreased PAI score) or healed (PAI <2), were assessed with the Chi-square test. RESULTS: No statistically significant difference in periapical healing was found between three groups. CONCLUSION: After 1-year evaluation, no difference in periapical healing was found between single-visit treatment and multi-visit treatment groups with the given sample size.

Pulpectomies in primary mandibular molars: a comparison of outcomes using three root filling materials.

AIM: To evaluate the outcome of root canal treatment in primary teeth using three root canal filling materials - RC Fill, Vitapex and Pulpdent root canal sealer. METHODOLOGY: The study was a single-centre, double-blind, randomized controlled trial carried out on 129 primary mandibular molars with necrotic pulps or irreversible pulpitis in 4- to 9-year-old children. Participants were selected based on specific inclusion and exclusion criteria and were randomly allocated into 3 groups: Group I - RC Fill [zinc oxide-eugenol (ZOE) with iodoform]; Group II - Vitapex (calcium hydroxide with iodoform); and Group III - Pulpdent root canal sealer (ZOE). The outcome measures were evaluated both clinically and radiographically at 6, 12 and 30 months according to modified American Association of Endodontists (AAE) criteria. The radiographic outcomes were assessed by two blinded and calibrated evaluators. Pearson's chi-square analysis was performed for both intention-to-treat (ITT) and per-protocol population. RESULT: The success rates of RC Fill, Vitapex and Pulpdent were 94%, 90% and 97%, respectively, at 30 months and the differences were not significant (P = 0.137). CONCLUSION: All three materials were found to be equally effective root filling materials for primary molars with necrotic pulps and irreversible pulpitis at 30 months. However, long-term follow-up until the eruption of the permanent successor teeth is needed for more definitive assessments.

Influence of calcium hydroxide-loaded microcapsules on osteoprotegerin and receptor activator of nuclear factor kappa B ligand activity.

INTRODUCTION: Calcium hydroxide (Ca[OH]2) microcapsules were synthesized to allow controlled release of Ca(OH)2. The aim of this study was to evaluate the influence of Ca(OH)2 microcapsules on osteoprotegerin (OPG) activity, receptor activator of nuclear factor kappa B ligand (RANKL) activity, and the OPG/RANKL ratio compared with pure Ca(OH)2 powder and Vitapex (Neo Dental Chemical Products Co Ltd, Tokyo, Japan). METHODS: One formula of Ca(OH)2 microcapsules was evaluated, and pure Ca(OH)2 powder was used as a control. A commonly used Ca(OH)2 medication containing an oily vehicle (Vitapex) was also evaluated, and the in vitro release profile of Vitapex was studied. The human osteosarcoma cell line MG63 was used to evaluate the influence of Ca(OH)2 microcapsules, pure Ca(OH)2 powder, and Vitapex on OPG and RANKL activity. The relative messenger RNA (mRNA) expression of OPG and RANKL was determined by real-time polymerase chain reaction. The protein expression of OPG and RANKL in supernatants was measured using enzyme-linked immunosorbent assay. RESULTS: Vitapex prolonged the release of Ca(OH)2 compared with pure Ca(OH)2 powder, and the release rate of Vitapex was faster than that of the microcapsules. The OPG/RANKL ratio in the microcapsules group was up-regulated at both the mRNA and protein levels compared with the negative control group and the pure Ca(OH)2 powder group. The ratio in the Vitapex group was lower than the microcapsule group both at the mRNA and protein levels. CONCLUSIONS: Ca(OH)2 microcapsules increased the expression of OPG although they did not increase the expression of RANKL compared with pure Ca(OH)2 powder and Vitapex. This increase in expression led to an increase in the OPG/RANKL ratio and eventual inhibition of osteoclast activity.
