Recurrence of odontogenic keratocysts and possible prognostic factors : review of 455 patients

To describe epidemiological features of 565 Chinese patients with odontogenic keratocysts (OKC), to investigate possible prognostic factors related to recurrence, and to analyse features of recurrent OKC (rOKC). A retrospective chart review of 565 cases of OKC treated between 2003 and 2015 was undertaken. The probability of recurrence related to prognostic factors including large size, cortical perforation combined with involved teeth in the lumen of the cyst, inflammation, sites of the involved lesion, sex, and daughter cyst variables were analysed. The subsequent relapse of each OKC was compared. Patients ranged in age from 7 to 81 years (mean age, 28.4 years) and, of those affected, 66.9% were male and 33.1% were female. Mandibular OKC occurred in 63.01% and 36.99% occurred in the maxilla, 80.53% of patients had non-rOKC, 10.44% rOKC, and 9.03% had multiple OKC lesions. Enucleation with preservation of the involved teeth in the cystic lesion combined with cortical perforation was statistically associated with high recurrence rate, as were daughter cysts, and multilocular lesions. The number of recurrences and the average time (in years) to relapse decreased from the first relapse of OKC to the third relapse, and the difference was significant (P<.05). Preservation of the involved teeth combined with cortical perforation appeared to be a potential prognostic factor associated with high recurrence. The follow-up evaluation period for rOKC with ? 2 previous treatments should be shorter than for first-time rOKC. The decreasing average duration (years postoperatively) to relapse was related to the number of rOKCs, timing of relapse, and rOKC type

Occurrence des traumatismes alvéolo-dentaires aux cliniques universitaires de Kinshasa: deuxième partie, étude préliminaire de 93 cas

Introduction: L'objectif de cette étude était d'analyser les caractéristiques épidémiologiques cliniques des fractures alvéolo-dentaires aux cliniques universitaires de Kinshasa/RDC. Méthodes: Étude transversale de 7 ans, réalisée dans le département d'odontostomatologie, service de stomatologie et de chirurgie maxillo-faciale/cliniques universitaires de Kinshasa de Janvier 2007 à Décembre 2014. Résultats: Sur les 93 dossiers colligés, le sexe masculin était prédominant (66,7%) et l'âge le plus prévalent se situait entre 20 ans et 29 ans. Les causes les plus fréquentes ont été les agressions/rixes (52,7%) et la luxation dentaire a été le type des lésions la plus fréquente avec 52,7%. La RX retro-alvéolaire été réalisée dans 75,7%, et le blocage mono-maxillaire fut le type de traitement le plus réalisé (60,2%). Conclusion: L'analyse de profil clinique des traumatismes alvéolo-dentaires aux cliniques universitaires de Kinshasa est celui d'un adulte jeune de sexe masculin, présentant des luxations dentaires des maxillaires dont les causes sont les agressions/rixes

A combined nasolabial and infra-nasal bi-lobe flap design with double transposition for reconstruction of the ipsilateral upper and lower lips associated with the commissure defect

Several classical flap variations have been designed to reconstruct lip and commissure defects. Although most of these variations maybe the best option for repairing defects, there is an increasing risk of anatomic distortion and functional disability, mostly in older persons. Herein, we present a combined nasolabial and infra-nasal bi-lobe flap design with double transposition, which was used to concomitantly close the upper and lower lips associated with commissure defects

Epidemiologic analysis of dental cellulitis in Kinshasa city (the Democratic Republic of the Congo)

Introduction: The study aimed to determine the prevalence, describe the sociodemographic profile of individuals with dental cellulitis, and identify its associated factors in a population of Kinshasa. Materials and methods: This was a cross-sectional analytical study conducted in October 2017 in five hospital departments in Kinshasa. The sample population consisted of patients with dental cellulitis. Sociodemographic data and factors associated with dental cellulitis were evaluated. Results: Dental cellulitis was found in 12.5% of the subjects, with a slight female predominance (58.2%). A significant difference between patients with cellulitis and those without cellulitis was observed for the following variables: education level, unemployment, and low socioeconomic status (p < 0.05). Dental carious lesions (93.7%) were the most common causative factor, and self-medication (100%) and poor oral hygiene (83.5%) were risk or contributing factors. Univariate analysis showed that for people of ages 16–59 and ≥60 years, education level, unemployment, sugar consumption, and low socioeconomic status were significantly associated with dental cellulitis. A multivariate logistic regression analysis showed that people of ages ≥60 years [odds ratio (OR) 3.12, 95% confidence interval (CI) 1.169–4.14, p = 0.014], non-university status (OR 2.79, 95% CI 1.68–4.64, p < 0.001), unemployment (OR 2.27, 95% CI 1.73–4.20, p = 0.005), sugar consumption (OR 3.17, 95% CI 1.71–4.94, p = 0.036), and low socioeconomic status (OR 2.60, 95% CI 1.85–3.01, p = 0.014) were independently associated with dental cellulitis in the study population. Conclusion: Dental cellulitis is a public health problem in the city of Kinshasa, the Democratic Republic of Congo
