External tooth resorption associated with a peripheral odontogenic fibroma: review and case report.
No full textThe purpose of the study is to document a rare case of a peripheral odontogenic fibroma with associated cervical and coronal tooth resorption in a 38 year old woman. Histopathological features are described, the clinical management outlined and follow-up observations over 27 years detailed. The exophytic firm lesion, coral pink in appearance, located on the labial aspect of a maxillary right lateral incisor was excised, fixed in formalin and prepared for histological evaluation. The resorption cavity and adjacent soft tissue were treated by the topical application of trichloroacetic acid prior to restoration with a glass-ionomer cement and subsequent root canal treatment. Histologically, the body of the lesion was characterized by the presence of odontogenic epithelium embedded in a mature fibrous stroma. Areas of dystrophic calcification could also be identified. The features were consistent with a diagnosis of a peripheral odontogenic fibroma. The clinical result of treatment assessed 27 years postoperatively showed no evidence of recurrence of the peripheral odontogenic fibroma. External cervical and coronal tooth resorption can, on rare occasions, prove to be a clinical feature associated with peripheral odontogenic fibroma. Treatment of the tumour mass and the resorptive lesion can provide a successful outcom
Ultrasound examination with color power Doppler to assess the early response of apical periodontitis to the endodontic treatment
No full textObjectives: The purpose of this study was to assess the possibility to detect early vascular changes in apical periodontitis (AP) using ultrasound examination with color power Doppler (US-CPD) and to establish a correlation between the early response of AP to treatment and its potential healing. Materials and methods: Twenty-one apical lesions were visualized with US-CPD before endodontic treatment, 1 week after the first access to endodontic system and 4 weeks after root canal obturation. A differential diagnosis between cystic lesions (CLs) and granulomatous lesions (GLs) was attempted. The vascular modifications were then correlated with long-term radiographic follow-up using Fisher’s exact test. Results: The decrease or disappearance of vascular flow observed in AP 4 weeks after root canal obturation was significantly related to a healing trend (p = 0.0206) of the lesions. Combining the data with preoperative US-CPD diagnosis showed a reproducibility for GLs only (p = 0.0022). Conclusions: This study showed the possibility to detect early vascular changes in AP using US-CPD, correlating them with a healing trend after endodontic treatment. Future investigations should be conducted and more attention should be dedicated to the potential of this alternative and biologically safe imaging technique. Clinical relevance: US-CPD in endodontics may be a helpful tool to identify healing processes after endodontic treatment and to understand the behavior of different forms of AP
Unconscious Racial Bias May Affect Dentists’ Clinical Decisions on Tooth Restorability:A Randomized Clinical Trial
No full textMethods: In this single-center cross-sectional survey, 57 dentists were given a clinical scenario in combination with a patient’s relevant clinical photographs and radiographs depicting either a Black or White patient presenting with a decayed tooth and associated symptoms of irreversible pulpitis. Explicit bias was measured through a questionnaire, which evaluated participants’ course of treatment, strength of recommendation, and their perception of patients’ dental cooperativeness. Implicit bias was evaluated through brief implicit associate tests. Results: Recommendation for root canal treatment (RCT) in the White patient condition was significantly higher than in the Black patient condition (χ2 = 4.77, P < 0.05). Overall, participants were significantly more likely to recommend root canal treatment to White patients (t = 2.46, P = 0.0172) and significantly more likely to recommend extraction for Black patients (t = 3.03, P = 0.0034). In total, 91.23% and 78.95% of all participants displayed high Brief Implicit Association Test race and cooperation scores, respectively, showing a pro-White bias in both categories. This trend was shown to be irrespective of the patient condition. Conclusions: Dentists’ decision making was affected by the race of the patient, resulting in a greater likelihood of extractions (less RCT) for Black patients presenting with a broken-down tooth and symptoms of irreversible pulpitis. Knowledge Transfer Statement: The results of this study can be used by clinicians to understand the impact that unconscious racial bias may have on their treatment planning decisions. This information can create awareness, thereby reducing the impact that potential biases can have on the treatment patients receive.</p
Valutazione dello stato della salute periapicale in un campione di popolazione sarda.
No full textScopo: scopo del presente lavoro è stato
quello di valutare la prevalenza delle
periodontiti periapicali (AP), la qualità
del trattamento canalare e dei restauri
coronali degli elementi trattati endodonticamente
in un campione di popolazione
sarda adulta.
Metodologia: questo studio è stato effettuato
su 318 radiografie panoramiche
appartenenti a pazienti sottoposti negli
anni 2002-2004 a prima visita odontostomatologica
presso la Clinica Odontoiatrica
dell’Università degli Studi di
Cagliari. I radiogrammi sono stati esaminati
da due osservatori indipendenti, opportunamente
calibrati (Test Kappa di
Cohen), i quali hanno proceduto alla
raccolta dei dati relativi alla presenza di
lesioni periapicali a carico degli elementi
dentali con e senza alcun trattamento
endodontico, alla qualità del riempimento
canalare e dei restauri coronali
dei denti già trattati endodonticamente.
L’analisi statistica è stata eseguita mediante
applicazione dei test Anova e Chiquadro.
Risultati: sono state esaminate 318 radiografie
panoramiche appartenenti a
136 pazienti di sesso maschile e 192 di
sesso femminile. Rispetto ai 7.287 elementi
esaminati, sono state osservate
579 lesioni periapicali e 180 trattamenti
canalari. La maggior parte dei restauri
coronali a carico dei denti già trattati
endodonticamente è stata considerata
inadeguata. È stata messa in evidenza
una correlazione significativa tra la presenza
di periodontiti apicali e la qualità
del riempimento canalare (P<0,001). Per
quanto riguarda gli elementi trattati endodonticamente,
non è stata stabilita alcuna
correlazione tra la qualità del restauro
coronale e il loro stato di salute
periapicale.
Conclusioni: sulla base dei risultati del
presente lavoro, la prevalenza delle periodontiti
periapicali è risultata elevata
e in stretta correlazione con la qualità
del trattamento endodontico.Aim: the aim of this study was to determine
the prevalence of apical periodontitis
(AP), and the quality of root fillings
and of coronal restorations in an
adult population attending the Dental
Clinic at the University of Cagliari
(Italy) during the years 2002 to 2004.
Methodology: 318 panoramic radiographs
from patients attending the Dental
School Clinic for the first time during
the years 2001-2004 were used in this
study. The radiographs were examined
and evaluated for the presence of periapical
lesions, the presence and quality of
endodontic treatment, and the presence
and quality of coronal restorations in
all present teeth except for the third molars.
The examinations were performed
by two independent observers who were
calibrated using Cohen’s K test. Statistical
analyses were performed using the
Chi –square and ANOVA tests.
Results: a total of 318 radiographs were
examined: 136 from males and 182
from females. Of the 7287 teeth that
were observed, 579 had apical periodontitis
and 180 of these had had endodontic
treatment. The majority of endodontic
obturations were considered inadequate.
There was a significant correlation
between the presence of apical periodontitis
and the poor quality of the
root canal obturation (P < 0.001). No significant
correlation was found
between the quality of coronal restoration
and the periapical status of the
treated teeth.
Conclusions: according to the present
study, the prevalence of apical periodontitis
was high and adequate root canal
fillings were associated with a lower
prevalence of the disease
The management of deep carious lesions and the exposed pulp amongst members of two European endodontic societies: a questionnaire-based study
Full text linkAims: To investigate and compare views on management of deep caries and the exposed pulp by Endodontic Society members in Ireland (Irish Endodontic Society [IES]) and Italy (Accademia Italiana di Endodonzia [AIE]). Further aims were to investigate the influence of patient-related factors (age, symptoms) and operator-related factors (material choice, antibiotics) on management. Methodology: A structured online questionnaire containing two cases (an 18- and 45-year-old) and two scenarios (± mild symptoms), including history and radiograph, was sent to IES and AIE members. The answers were analysed using chi-square and Fisher's exact test (P < 0.05). Results: In total, 120 dentists participated, representing 49% of the AIE and 48% of the IES membership. Age distribution was similar between the societies; however, most AIE members had no further qualifications (63%), while IES respondents generally had a postgraduate endodontic qualification (71%). AIE respondents carried out a larger volume of vital pulp treatment (VPT) per month, with 69% carrying out over five cases, compared with 22% of IES respondents. The presence of patient symptoms significantly altered treatment planning decisions (P < 0.001) with root canal treatment (RCT) more frequently selected in both societies. Patient age significantly influenced treatment choice in the absence (P = 0.043) or presence (P = 0.012) of symptoms with less VPT advocated in older patients. There were no significant differences in the treatment of a young patient in the presence (P = 0.302) or absence of symptoms (P = 0.297); however, older patient management differed between the societies for symptomatic (P = 0.041) and asymptomatic scenarios (P = 0.044) with significantly more RCTs carried out in the AIE than the IES. Hydraulic calcium silicate materials were commonly selected, accounting for 81% of IES and 69% of AIE VPT materials, although younger members of the AIE preferred calcium hydroxide materials. Younger dentists in both societies prescribed less RCT than older age groups. Conclusions: Although VPT is carried out by members of both societies there was no consistency regarding the most appropriate management for the exposed pulp or the VPT material of choice. Patient symptoms and age significantly influence the decision-making process and invasiveness of treatment. Hydraulic calcium silicate materials were the most commonly advocated material in all groups except young AIE members who preferred calcium hydroxide

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
