Permanent First Mandibular Molar: Loss Prevalence and Pattern among Saudis in Al-Ahsa

Abstract

Objectives The permanent first mandibular molar (PFMM) is the first tooth to erupt, usually at the age of 6 years. It is the most effective oral masticatory unit due to its wide occlusal surface and its role in favorable occlusion. This study describes the prevalence of PFMM loss and the reasons for extraction in a group of King Faisal Dental Complex Clinics (KFUDC) Saudi attendees. In addition, to report postextraction complications, consider the gender, age, and the time elapsed from the moment of the extraction. Materials and Methods A cross-sectional study was performed in January to April 2020, focusing on the loss of PFMM among a group of Saudis attending KFUDC in Al Hofuf, Saudi Arabia. A total of 417 participants were recruited. The inclusion criteria were adults aged ≥ 18 years. The principal investigator performed all the necessary measures for calibration in the forms of training on clinical examination and interviews. Statistical Analysis Data were analyzed using the Statistical Package for the Social Science, version 25 (SPSS Inc., Illinois, United States). Result Four hundred seventeen attendees participated in the present study. Majority were males 73.9% (308), and 26.1% (109) females. A third, 30% (125), reported missing PFMM; the overwhelming majority reported the reason for extraction as caries 93.6% (117).On clinical examination, 80.8% (101) had complications; drifting of adjacent teeth was the most common complication, 57.6% (72), followed by supraeruption in 23.2% (29).More males than females reported missing PFMM (22.8 and 7.2%, respectively), and those ≥ 25 years reported more missing PFMM than younger (17.5 and 12.5%, p ≤ 0.000). Those confirmed with systemic diseases reported more missing PFMM than their counterpart (23.3 and 6.7%, p ≤ 0.01).Those with good oral hygiene reported less missing PFMM than their poor oral hygiene counterparts (27.8 and 34%). Those who had good knowledge about the complications of early extraction of PFMM stated less missing PFMM than their counterparts (15.6 and 14.4%, p ≤ 0.01). Conclusion This study indicated that PFMM were the most common extracted tooth. Caries is the principal reason for tooth extraction among the studied population, followed by periodontal diseases. Emphasis on preventing dental caries is essential to maintain a socially and economically productive life and reduce the burden of oral disease.

Timing for extraction of permanent first molars in school aged children: a pilot study

“…Recent epidemiological studies exhibited that 60-90% carious lesions occurred in the pits and fissures of permanent first molars, despite the preventive ongoing programs [15]. More than 50% children over 11 years age had been reported for caries in the permanent first molars [7]. The preferred therapy in severely compromised permanent first molar with poor prognosis might be extraction, although being non-restorable.…”

“…The most effective extraction time is the childhood as suggested by previous studies, however with limited scientific evidence [2,7,8]. Eichenberger et al [9] finds better clinical outcomes after P1Ms extraction in younger children (8-11.5 years) compared to older age [10].…”

Radiographic Assessment of Permanent First Molars Among Adults in Riyadh: A Retrospective Study

“…Our study was focused on adults (>18 years old). To the best of our knowledge, no studies primarily focused on adult populations except for a recent clinical study [ 5 ]. However, their study focused on mandibular first permanent molars only.…”

“…Unfortunately, first permanent molars are the highest susceptible teeth to caries due to their early eruption [ 3 ]. Caries was found to be the main reason for permanent tooth extraction [ 4 , 5 ]. Previous studies in Saudi Arabia have found an 83% prevalence of caries among children, and the prevalence of missing FPMs was higher with mandibular FPMs than the maxillary FPMs [ 6 , 7 ].…”

Comparative Assessment of Oral Health Attitudes and Behaviors of First-Time and Previous Dental Patients Undergoing Exodontia Treatment During the COVID-19 Pandemic in Private Dental Clinics in Riyadh City, Saudi Arabia

“…This finding agrees with past studies conducted in Saudi Arabia. 39 , 40 Caries and periodontal disease are mostly avoidable causes of tooth loss if detected early during routine dental visits. However, first-time and previous attendees visited dental clinics at a late stage of the disease that required teeth extraction either due to the high cost of the treatment or because there was no other treatment option left.…”
