Background and Objectives: Opportunistic oral fungal infections have spread, especially in denture wearers. Denture stomatitis (DS) is a common inflammatory reaction with multifactorial etiology. It is usually associated with Candida species, particularly Candida albicans, due to its high virulence, ability to adhere and form biofilms on oral cavity tissues and denture surfaces. This study highlights the risk factors of Candida albicans-associated denture stomatitis. The study was carried out at Prosthodontics Departments at the Faculty of Dentistry-Sana'a University, Sana'a city -Yemen. Study design:The study group consisted of 288 denture wearers suffering from DS. Data including demographic data of the patients, clinical information, and risk factors of DS recorded in predesigned questionnaire.Result: There was a significance association between male (OR=2.33, p<0.001), older age patients (OR=6.8, p<0.001), denture poor fitness (OR=8.2, p< 0.001), older age denture (OR=14.6, p<0.001), denture manufacturers under supervision of general dentist (OR=2.9, p<0.001), non-ideal denture quality (OR=4.8, p<0.001), irregular denture cleaning (OR=2.1, p<0.001), and often overnight denture wear (OR=1.7, p=0.04). Conclusion:Management of predisposing risk factors is key in order to prevent recurrence of DS. Treatment methods may consist of: treatment of any underlying systemic risk factors, improvement in the fit of existing dentures, replacement of existing dentures, improved denture hygiene.

Objective: Impacted maxillary and mandibular canine is a frequently encountered clinical problem. The objective of the present study was to determine the prevalence of impacted canine in patients visiting an Orthodontic Clinic in Sana'a city, Yemen. Materials and methods: Patients were examined in order to detect the impacted canines by radiographs. This study comprises data from randomly selected 5287 patients. Panoramic radiographs of 5287 were selected irrespective of sex, caste, nutritional and socio-economic status Angulation and depth of impacted canine were also assessed. Results: Out of 5287 surveyed subjects, 188 patients (3.55%) were determined to have canine impactions of whom 123 female and 65 male (Chi-square = 18.667, df = 1, P = 0.00001). Of those determined with canine impaction, 168 presents with impacted maxillary canines, 8 presents with the impacted mandibular canine and 12 present with impacted canine in both maxillary and mandibular arch. The difference was statistically significant (Chi-square = 157.362, df = 1, P = 0.0000). 138 subjects present with unilateral impaction, while the rest of the sample (50 subjects) present with bilateral impaction. Mesioangular impaction was found in 137subjects (68.5 %) and only 3 subjects (1.5 %) demonstrated distoangular impaction. Conclusion: Based on the study results, the canine impaction was reported in (3.55%) of Yemeni population included in the survey. Most of the canine impaction occurs in maxillary arch being more prevalent in female and unilateral in mesioangular direction.

Background Cerebral palsy (CP) represents for children an important problem of health and affects roughly 2 per 1000 live births and is the most common pediatric developmental motor disability. Therefore, the purpose of this study was to determine the prevalence, type and severity of malocclusion and oral habits in children with Cerebral Palsy (CP) and to compare them with a control group of healthy children in Sana’a city. Material and Methods A prospective, case–control study was made of two groups, a cerebral palsy and a control group. The study population consisted of 60 children who had CP, and a control group of 60 matched children who had no known physical or mental handicap. Data were collected using a questionnaire and assessment for malocclusion was done clinically. The patients were compared with equal number of age-matched controls. The inclusion criteria were individuals aged over 6 years; absence of previous orthodontic treatment; no missing permanent first molars Results Results showed an increased prevalence of malocclusion in children with cerebral palsy. Molar class II relationship was statistically higher in cerebral palsy children than healthy control (P = 0.001). Cerebral palsied children are likely to have a significantly increased protrusion of the anterior teeth (P < 0.001) when compared with normal children. Mouth breathing and Tongue thrust. Habits were significantly higher in the CP group (p = 0.0001) when compared with normal children. Conclusion The prevalence of malocclusion was higher in children with Cerebral palsy than in normal children, and the present study concludes that in children with Cerebral Palsy, more oral Habits problems due to oral motor dysfunctions are common and problems of mouth breathing and Tongue thrust produce different malocclusion and poor oral hygiene complications in these children.
