Prevalence and Pattern of Third Molar Impaction in Sample of Yemeni Adults

 

Abstract

Background and objectives: Third molar impaction is an important clinical issue because impacted teeth predispose to periodontal disease such as pericoronitis, periodontitis, and other problems such as cystic lesions, neoplasm, root resorption and can cause detrimental effects on adjacent tooth resulting in pain, discomfort and loss of function. The pattern of third molar impaction in Yemeni population has not been described; thus, the aim of this retrospective radiographic study was to determine the prevalence and pattern of third molar impaction, angulation and level of eruption in sample of Yemeni adults.

Materials and methods: The study sample of 609 patients chosen randomly from patients who visited MASS x-ray centers in Sana’a and Ibb cities. The data collected included presence and impaction state, angulation, and depth of impaction of third molars.

Results: Out of total population, 236 (38.8%) showed at least one impacted third molar. The condition was slightly higher in females (40%) than in male (35.1%). The incidence of impacted lower third molars were most frequent (22.8%) than impacted upper third molar (15.9%). The most common level of impacted third molars was level II (43.8%) the most common angulation of impaction in the mandible was the mesioangular (76.8%), the most common level of impaction was level II (43.8%) and position of impaction was B (72.6%). There was no significant difference in the frequency of impaction between the right and left sides of both jaws.

Conclusion: This study found that about 40% of Yemeni adult patients ranging in age from 18-28 years had at least one impacted third molar.

  Authored by  Chaza Kouchaji, Introduction ECC experience is defined as the presence of one or more decayed (noncavitated or cavitated lesions), missing (due to caries) or filled tooth surfaces in any primary tooth in a child aged 71 months or younger [1]. ECC is the most commonly observed chronic disease in children [2]. ECC continues to be pandemic disease according to World Health Organization. The prevalence generally ranges from 27%-48%, with more than 76% reported from the Middle East [3]. While in Syria the burden of ECC amongst Syrian children aged 3-5 years was dmft value of 4.25 ± 4.2 per child [4]. Main risk factors that contribute to the formation of ECC were microbiological, environmental and dietary factors [5]. The clinical appearance of the teeth in S-ECC in a child 2, 3, or 4 years of age is typical and follows a definite pattern. There is early carious involvement of the maxillary anterior teeth, the maxillary and mandibular first primary molars, and sometim...

Oral Pyogenic Granuloma: Case Report of an Atypical Presentation

Abstract “Granulomas seem to be a defensive mechanism that triggers the body to “wall off” foreign invaders such as bacteria or fungi to keep them from spreading” [1]. Pyogenic granuloma is a relatively common benign skin growth that consists of vascular nodules of proliferating capillaries [2]. They grow rapidly and often occur following a minor injury or trauma, most likely as a vascular or fibrous response to injury or irritant [2]. Ultimately, the etiology of pyogenic granuloma is still unknown. Oral pyogenic granuloma is most commonly found on the gingiva, followed by the lips, tongue, buccal mucosa, and hard palate [3]. It often presents as a red, smooth, or lobulated exophytic lesion which can be pedunculated or sessile and often bleeds on provocation [4]. A microscopic evaluation of pyogenic granuloma often reveals that the lesion is fully or partially covered by parakeratotic or non-keratinized stratified squamous epithelium. The majority of the lesion is formed by a lobulated...

Hepatitis B Virus among Dental Clinic Workers and the Risk Factors Contributing for its Infection

Abstract Objectives:  Dental clinic workers (DCWs) in Yemen have an additional risk of getting infected with HBV from their workplace and till now they are not routinely vaccinated against HBV infection. This study aimed to estimate prevalence of hepatitis B virus infection and associated risk factors among DCW in selected dental clinics in Sana’a city. Study design:  Data were acquired from a cross sectional survey conducted among DCWs in 2014 at the Faculty of Dentistry, Sana’a University, in Sana’a city. A proportionate to size random sample was drawn per DCW category. A structured questionnaire was used to collect data about socio-demographic characteristics and risk factors. ELISA was used to test sera for HBV markers. Result:  The study included 246 dentists and 263 dental assistants, the sero-prevalence of current hepatitis B virus infection was 6.1%; while prevalence of life time exposure to hepatitis B virus infection was 18%. Prevalence of needle stick injuries,...
