“…In Europeans, the mandibular second premolar is the most frequently absent tooth, followed by the maxillary lateral incisor and the maxillary second premolars (Bergstrom, 1977;Rolling, 1980;O'Dowling & McNamara, 1990;Aasheim & Øgaard, 1993;Nordgarden et al, 2002). In the Malaysian (Nick-Hussein & Majid, 1996), Israeli (Chosack et al, 1975) and American populations (Muller et al, 1970), the most frequently missing teeth are the maxillary lateral incisors. Focusing on MLIA the prevalence varies between 0.8 and 4.25% (Horowitz, 1966;Muller et al, 1970;Thilander & Myrberg, 1973;Magnusson, 1977;Rolling, 1980;Aasheim & Øgaard, 1993;Johannsdottir et al, 1997;Tavajohi-Kermani et al, 2002).…”
