AIMS AND OBJECTIVES To evaluate the role of prophylactic antibiotics, if any, in the removal of mandibular impacted third molars. PATIENTS AND METHODS A total of 89 patients were randomly allocated in 3 groups (group 1, placebo; group 2, amoxicillin 1 g orally 1 h before surgery; and group 3, metronidazole 800 mg orally 1 h before surgery). RESULTS Of the 89 patients, 5 had surgical wound i...

PURPOSE The purpose of this study was to determine the incidence of Inferior Alveolar Nerve (IAN) damage after surgical removal of lower third molars, to identify the cause and to construct a predictive model to assess the risk of IAN injury. MATERIALS AND METHODS Patients were selected from the out patient department after proper clinical and radiological evaluation of mandibular third molar...

Tooth autotransplantation defines as transition of one tooth from one position to another, in same individual. It is a biological procedure in which teeth have the potential to induce alveolar bone growth. It can be applied in patients before adolescence growth is finished. It significantly reduces time and cost compared to implants. Healing rapidly occurs and function is regained almost immedi...

The third molar development was studied on the basis of 1700 panoramic radiographs analysis of randomly selected individuals in the age ranging between 5-21 years inclusive. Each age group consisted of 100 probands--50 boys and 50 girls. The characteristics of the third molar development were following: time of dental follicle formation--dynamics of development--the most frequent stages of thir...

I start by defining the cosmological parameters H0, Ωm and ΩΛ. Then I show how the age of the universe depends on them, followed by the evolution of the scale parameter of the universe for various values of the density parameters. Then I define strategies for measuring them, and show the results for the recent determination of these parameters from measurements on supernovas of type 1a. Implica...

A number of real-world search tasks (i.e. police search, detection of improvised explosive devices (IEDs)) require searchers to search exhaustively across open ground. In the present study, we simulated this problem by asking individuals (Experiments 1a and 1b) and dyads (Experiment 2) to search for coin targets pseudo-randomly located in a bounded area of open grassland terrain. In Experiment ...

In clinical dentistry third molar have great prevalence. These teeth are commonly found to be impacted and sometimes it’s may absent in the oral cavity. The aim of the study was to evaluate the prevalence of different pattern, angulation of third molar impaction and third molar agenesis between different ages of different races. Several electronic databases such as Google Scholar, PubMed, Web o...

Times of eruption of third molars were studied in rural Nigerian adolescents--125 males and 133 females. Results of this study showed that the average age for the initial eruption of third molars was 15 years in male subjects and 13 years for female subjects. The incidence of eruption showed a steep rise after the age of 16 years for male subjects and 14 years for female subjects. By the age of...
